How Does Cash App Make Money? The Business Model Explained

How does Cash App make money when sending a friend $20 for pizza costs you nothing? In the second quarter of 2026, about $87 billion flowed into the app, and roughly 59 million people used it in June alone.

So where does the money come from?

It’s a fair question, yet it’s the one most “how does Cash App make money” articles answer badly. Instead, they list a few fees, mention Bitcoin, and stop. But the real story of the Cash App business model is more interesting. Cash App gives away the one thing everybody uses it for, then earns its living on everything that happens around it: cashing out fast, spending on the card, borrowing against your next paycheck, buying something now and paying later. In fact, each of those is a separate business with its own economics.

We went through Block’s own numbers (Q2 2026 shareholder letter), Cash App’s published fee pages and terms, and the regulatory record to put this together. Where a number comes from a source, we say so. Likewise, where it’s our own arithmetic, we say that too. By the end you’ll know exactly how each revenue stream works, which ones matter most, which ones are smaller than people think, and what a founder building a payments app can borrow from the playbook.

How does Cash App make money? The short version in one table

So if you only have a minute, this is the map. We’ll walk through each row properly below.

Revenue stream	Who pays	How it works
Instant transfers	The person cashing out	A percentage fee to get money in your bank in seconds instead of days.
Cash App Card	Merchants, through the card network	A slice of the swipe fee (interchange) every time you tap or swipe.
Cash App Borrow	The borrower	Short-term loans with a flat fee, repaid from deposits.
Afterpay and Cash App Pay	Merchants	Retailers pay to offer buy-now-pay-later and one-tap checkout.
Bitcoin and stocks	The trader	Fees and spreads on buying and selling.
Business accounts	The business	2.75% taken from each payment received.

First, what Cash App actually is (and isn’t)

Cash App is not a bank. Block, the company behind it, says so directly in its own filings: it’s a financial services platform, and the banking products run through third-party partner banks. That detail matters later, because it shapes both the costs and the regulation.

In fact, the app started life in 2013 as Square Cash, a way to email someone money. Square, the card-reader company, built it. The name changed to Cash App, the features multiplied, and in December 2021 Square renamed itself Block so the Square brand could belong to the seller business it was built for. Then, a month later, in January 2022, Block closed its purchase of Afterpay, the buy-now-pay-later company. In fact, that one deal is a big part of why Cash App makes money from shopping today.

Today Cash App is a bundle of things: peer-to-peer payments, a bank-style balance, a debit card, direct deposit, loans, stock and bitcoin trading, even a phone plan. Block’s Q2 2026 letter mentions a $40-a-month unlimited 5G plan called Cash App Mobile, and says nearly 4 million monthly actives already pay their phone bills through the app.

Here’s the number that explains the whole strategy. Still, of those 59 million monthly users, 9.4 million are what Block calls “primary banking actives”: people who bring in paychecks or spend at least $500 a month across the app. That’s about one in six. They’re the customers Cash App is really built for, because they’re the ones who use the profitable features.

Stream 1: How Cash App makes money from instant transfers

First up is the one you’ve probably paid for without noticing.

When someone sends you money on Cash App, it lands in your Cash App balance instantly. That part is free. But if you want it in your actual bank account, you have a choice. A standard transfer is also free, but takes one to three business days. An instant transfer, on the other hand, takes seconds and costs a percentage.

However, the exact percentage depends on where you look, which is a small trap in itself. Cash App’s help pages list a range of 0.5% to 1.75%, with a $0.25 minimum. The Terms of Service, which are the document that actually binds you, allow up to 2.5%, with a cap of $75 on any single fee. So our advice: trust the fee screen in the app at the moment you confirm. It shows the real number.

Why does this work as a business? Because impatience is a reliable product. In fact, most people who cash out instantly aren’t in a position to wait. For example, it’s a Friday, rent is due, and the standard transfer would land on Tuesday. They’ll pay 1% to avoid that. Cash App doesn’t publish what an instant transfer costs it to run, but a percentage fee on a small transfer clearly leaves room.

The honest limit is size. Instant-transfer fees are a steady earner, but they aren’t what’s driving Cash App’s growth. After all, they’re a fee on the way out, and Cash App would rather you didn’t leave at all. Which brings us to the card.

Stream 2: How Cash App makes money from the Cash App Card

The Cash App Card is a free Visa debit card linked to your balance. So every time you use it, the merchant pays a fee to accept the payment. That fee is called interchange, and it’s split between the card network, the bank that issued the card, and a few others. Finally, a slice of it ends up with Cash App.

However, Cash App doesn’t publish the exact cut, and it varies by transaction type. But Block does publish something useful: a monetization rate for what it calls Commerce Enablement. That’s gross profit divided by volume across Cash App Card, Cash App Pay, buy-now-pay-later and business payments. In Q2 2026, the rate was 1.65% on $56.5 billion of volume.

So in plain terms, for every $100 flowing through those products, Block kept about $1.65 as gross profit. Not revenue. Profit, after the direct costs of processing. Also, the rate has crept up from 1.53% a year earlier, and Block credits that mostly to Afterpay’s post-purchase product.

Besides swipe fees, the card does something that doesn’t show up as a line item: it makes Cash App sticky. Once your money lives in an app and you spend it with that app’s card, you stop moving it back to the bank. Therefore, every dollar that stays is a dollar that can earn swipe fees later.

The paycheck is the prize

The most valuable thing a Cash App customer can do is switch their paycheck to direct deposit into the app. Why? Because someone who gets paid there tends to spend from there, borrow from there, and rarely leaves. Block’s letter says “inflows per transacting active”, meaning how much money each active user brings in, reached $1,469 in Q2 2026, up 9% year over year. It also credits part of that rise to more customers bringing their paychecks into Cash App.

Look at that again. But monthly users barely grew in the last year (57 million to 59 million, or 3%). But the money each user brings in rose 9%. Cash App isn’t mainly finding new people. Instead, it’s getting more from the ones it has.

The small card fees

The card also generates a few direct fees, none of them large. For instance, ATM withdrawals cost $2.50 each, and the ATM operator may add its own charge. That said, Cash App reimburses its own fee if you get $300 or more in qualifying deposits or spend $500 or more in a month. Likewise, purchases in a foreign currency carry a 3% fee, which the same thresholds can waive for in-person spending. Finally, depositing paper cash at a retail partner costs $1.

These are friction fees. In short, they push you toward the free path, which is: get paid by direct deposit, spend by card, stay in the app.

Cash App Borrow: the fastest-growing source of Cash App revenue

If you want to know where Cash App’s growth is coming from right now, look here.

Cash App Borrow is a short-term loan, taken inside the app, repaid from the money you deposit. Instead of charging interest in the usual way, Cash App shows you a flat fee up front. Third-party guides commonly put that fee around 5% of the amount borrowed, so $100 out means $105 back, but treat that as a ballpark. The binding number is the one in your Summary of Loan Terms, shown before you accept.

Eligibility is the clever part. For example, Cash App’s own Borrow page says most people qualify by direct depositing $300 or more in paychecks each month, or by linking an outside account that shows $500 or more in monthly deposits. In other words, the loan is underwritten by how you use Cash App, not by a traditional credit file.

Repayment, meanwhile, is flexible: pay as cash comes in, in weekly installments, or in full on the due date. Anything still outstanding on the final due date is pulled automatically from your Cash balance or linked account. However, if you miss it, the loan agreement describes a one-time outstanding-balance fee and weekly overdue interest on what’s left.

How big is it?

Big, and it’s accelerating. So here’s the data: Block reports that consumer lending originations, which cover Cash App Borrow and its buy-now-pay-later products, hit $18.9 billion in Q2 2026. That’s up 59% from a year earlier, and the letter says the growth was driven largely by Borrow. A year before that, the quarterly figure was $11.9 billion.

Likewise, Block’s Financial Solutions segment, the home of lending, grew gross profit 43% year over year in the quarter to $1.29 billion. Block’s own explanation: Cash App consumer lending.

Here’s why this stream matters so much to the model. A loan fee, however, earns far more per customer than a swipe fee. But it only works if people repay. Block says its loan cohorts have had loss rates below 4% in every cycle it has seen, and it has built a near real-time credit score called Cash App Score from account activity. That’s management’s claim, and it’s worth reading with some care, but it explains the confidence. If the risk model holds, then each additional dollar of paycheck that moves into Cash App becomes the raw material for a loan.

It’s also the stream with the most scrutiny, which we’ll come back to in the risks section. (Our look at P2P lending apps covers the lender’s side of the same idea.)

Stream 4: How Cash App makes money from Afterpay and Cash App Pay

This is the stream that comes from the Afterpay deal. Afterpay lets shoppers split a purchase into installments with no interest. The shopper pays nothing extra, as long as they pay on time. The merchant pays Afterpay a fee, because it sells more when shoppers can spread the cost.

Meanwhile, Cash App Pay is the other half of the checkout story. It lets someone pay online or in a store using their Cash App balance, card or bank, with one tap. Also, Block’s Q2 letter says Cash App Pay is growing strongly, partly through bigger partners such as Instacart and Uber.

Together with the card, these two sit inside the Commerce Enablement number we met earlier: $56.5 billion of volume at a 1.65% monetization rate. Block’s letter says Commerce Enablement gross profit grew broadly across the buy-now-pay-later products and the Cash App Card. It also says the rise in the rate came from higher attach rates on Afterpay Post-Purchase, the option to turn a purchase you’ve already made into installments.

The business logic is straightforward. A merchant will pay a fee on each order because installments can lift its checkout conversion and basket size. Block doesn’t publish the merchant rates. Still, Cash App’s advantage is that it owns the shopper on the other side. After all, it already knows the person, their balance and their spending.

Stream 5: How Cash App makes money from bitcoin and stocks (big revenue, thin profit)

This is the section where most explainers mislead you, so it’s worth slowing down.

Cash App is a popular way for ordinary people to buy bitcoin. Block’s bitcoin ecosystem generated $1.89 billion of revenue in Q2 2026. That sounds enormous next to Cash App’s total gross profit of $1.97 billion. Add them up and you might conclude bitcoin is a huge slice of the Cash App business model.

It isn’t. In fact, that same quarter, bitcoin revenue produced only $72 million of gross profit. That’s 3.8 cents on every dollar.

Why the gap? When you buy $100 of bitcoin, Cash App’s revenue counts the full $100 you paid, because it sold you the coin. But the cost of acquiring that bitcoin is almost the same $100. What’s left, then, is a small fee or spread. It’s a pass-through business. So the headline number is large and the margin is tiny.

This is why Block reports gross profit as its main metric, and why you should too whenever you read a fintech’s numbers. Revenue tells you how much money touched the company. Gross profit, by contrast, tells you how much it kept.

It’s getting thinner, too. Block says bitcoin gross profit fell 31% year over year, and it blames two things: market conditions, and “a strategic decision to reduce the fee we charge on certain bitcoin transactions on Cash App.” Cash App chose to make less on bitcoin. That’s a deliberate trade. After all, cheaper trading keeps people active in the app, and active people are the ones who take the cards and loans that do earn real money.

What about stocks?

Cash App Investing lets you buy stocks, including fractional shares, from inside the same app. We couldn’t find a clear, current breakdown of stock-trading income in Block’s letter, so we won’t guess a figure. Instead, what we can say is the strategy mirrors bitcoin: low prices, easy access, and a reason to keep your money in one place. The Q2 letter also notes that Cash App has launched stablecoins, so a USDC balance and an ordinary dollar balance are interchangeable in the app. Expect more of this: crypto and investing as engagement tools first, earners second.

Stream 6: How Cash App makes money from business accounts

Anyone can open a free Cash App business account to take payments from customers. It’s popular with sole traders, market stalls, tutors, freelancers and small side businesses. Cash App’s help center says a 2.75% processing fee is taken from each payment a business account receives.

For a business, that’s in the same range as other payment processors. For Cash App, meanwhile, it’s a straightforward percentage on volume. It also does something quieter: every customer who pays a business through Cash App needs an account too, which pulls more people into the network.

There’s a rule worth knowing if you’ve ever wondered why a friend charged you a “fee” for a sale. Cash App’s terms say personal accounts are for personal use. The business account, instead, is the one built to take payments, and it’s the one that pays.

The small stuff and the new bets

Besides those six, add up the smaller items and you find a few other earners:

• Credit card funding. Sending money from a credit card carries a 3% fee. A bank account or debit card is free.
• Cash App Mobile. A $40-a-month unlimited wireless plan, with nearly 4 million monthly actives paying phone bills through the app.
• Cash App Tags. Tap-to-pay chips that link physical objects to your Cash Card. They’re a hardware product with a marketing edge: Block says each drop sold out within hours and drew over 3 million requests for future drops.
• Cash App Score. A credit score built from account activity. It’s an asset more than a product, because it feeds Borrow.

Still, none of these will rival Borrow or the card. But they do point to where the company is heading: a full financial life in one app, where each new feature adds another reason to stay.

Cash App revenue and profit: the numbers behind the business model

So it’s time to put the pieces on one page. These figures come straight from Block’s Q2 2026 shareholder letter (also filed with the SEC as an 8-K exhibit), unless marked as our own calculation.

Metric (Q2 2026)	Figure	Change vs a year earlier
Cash App gross profit	$1,973 million	Up 31%
Monthly transacting actives	59 million	Up 3%
Primary banking actives	9.4 million	Up 17%
Inflows per transacting active	$1,469	Up 9%
Commerce Enablement volume	$56.5 billion	Up 17%
Commerce Enablement monetization rate	1.65%	Up from 1.53%
Consumer lending originations (Borrow and BNPL)	$18.9 billion	Up 59%
Total inflows	$87 billion	Up 13%

Look at the first two rows together. Gross profit up 31%. Users up 3%. That gap is the entire story.

Next, here’s a quick bit of arithmetic of our own. Divide gross profit by monthly actives and you get roughly $26 per user for Q2 2025 and roughly $33 for Q2 2026. (That’s a simple average across all 59 million users, not a figure Block publishes, and plenty of those users are barely active.) Even so, it’s a rise of about a quarter in twelve months, from a user base that hardly grew.

It’s worth noticing what’s slowing, too. Coverage of Block’s earnings call says growth faces tougher comparisons in the second half, as Cash App laps the rapid rise of Borrow, and that management expects only low single-digit growth in actives. So a model built on deepening, not widening, has to keep finding new things to sell to the same people. For wider context on where that spending is happening, see these mobile payment statistics.

Want to read the numbers yourself?

Block publishes a shareholder letter each quarter on its investor site, and the Cash App table is on one page. Start there. Three habits will save you from misreading it:

1. Look at gross profit, not revenue. Revenue includes bitcoin sold at full price, so it inflates the headline.
2. Check the definitions in the footnotes. A “transacting active” is an account with at least one transaction in the month. That’s a low bar, so gross profit per active looks modest.
3. Compare growth in profit with growth in users. If profit grows far faster than users, then the company is monetizing harder, not just getting bigger.

The Cash App business model: free sending is the funnel

This is the part we’d tape to the wall if we were pitching a payments startup.

Peer-to-peer payments are the cheapest customer acquisition tool in fintech. After all, you can’t pay a friend through Cash App unless the friend has Cash App. So every payment is a small invitation.

But sending money itself earns almost nothing. So the product design is built around a staircase:

1. Send money free. Friends invite friends. Nobody has a reason to say no.
2. Keep a balance. The money lands in the app, so it tends to stay.
3. Get the Cash Card. Spending that balance earns swipe fees.
4. Move the paycheck in. Direct deposit makes Cash App the main account.
5. Borrow and buy later. Loans and installments turn that trust into revenue.

Notice that each step makes the next one easier. Someone who has a balance gets a card. Next, someone with a card gets their paycheck sent there. Finally, someone whose paycheck lands in the app has the deposit history that makes them eligible for a loan. The sequence isn’t an accident, since the eligibility rules for Borrow are literally written around paycheck deposits.

If you’re building something similar, the lesson is blunt: the free feature isn’t the product. It’s the front door. We’ve covered that pattern more widely in our guide to how free apps make money.

A worked example: what one engaged customer is worth

Numbers in a table only go so far. So here’s an illustration. It’s hypothetical, built from published fees and Block’s own ratios, so treat it as a sketch of how the pieces add up, not as data.

Meet Maya. She’s paid $1,800 every two weeks, and she has it direct deposited into Cash App. In a typical month she does this:

• Spends $1,200 on the Cash App Card. Block’s blended Commerce Enablement rate is 1.65%, so that’s roughly $19.80 of gross profit. (That blend includes Afterpay, so it overstates what a plain debit swipe earns. Read it as a loose guide.)
• Cashes out $400 instantly, once. At 1.5%, which sits inside the published 0.5% to 1.75% range, that’s $6.00.
• Borrows $100 to cover a gap. At a flat fee of about 5% (the third-party ballpark), that’s $5.00.
• Buys $50 of bitcoin. At Block’s overall bitcoin margin of 3.8%, about $1.90.

Add it up: about $32.70 a month, or roughly $390 a year.

Now compare that with the average. Block’s gross profit of $1.973 billion across 59 million monthly users works out to about $33 per user per quarter, or about $134 a year. So Maya is worth nearly three times the average user. In fact, she’s exactly the kind of person Cash App’s whole product is designed to produce: paycheck in, card out, small loan when needed.

That’s the real answer to “how does Cash App make money?” It doesn’t earn much from most of its users. But it earns a lot from a smaller group who use the app as their main account. Meanwhile, primary banking actives grew 17% last year to 9.4 million. In fact, they’re the people the whole product is built around.

How this differs from how a bank makes money

So if you’ve ever wondered why Cash App can skip fees that banks charge, the answer is in how each one earns.

A traditional bank, for example, mostly earns the gap between what it pays on deposits and what it charges on loans, plus fees for things like overdrafts. By contrast, Cash App’s card agreement says there are no monthly fees and no overdraft fees on the Cash App Card. It makes its money on activity instead: swipe fees from merchants, fees for speed, fees on loans and trades.

That shift has consequences. A bank wants you to keep balances high. Cash App wants you to keep moving money, because movement is what it earns on. It’s also why Cash App spends so much on features that nudge you to use it for everyday purchases rather than just holding cash.

One small wrinkle: Cash App itself is not a bank, although Block says it has now chartered its own bank, with the aim of leaning less on partner banks over time.

The uncomfortable part: risks and regulation

A fair look at how Cash App makes money has to include what it costs the company when things go wrong. Three areas stand out.

Fraud and customer service

In January 2025, the US Consumer Financial Protection Bureau ordered Block to refund consumers up to $120 million and pay a $55 million penalty, $175 million in total. The CFPB said Block’s investigations of unauthorized transactions were incomplete, so it ordered changes, including 24-hour live-person customer service. Block publicly disagreed with the CFPB’s characterization, but agreed to the settlement.

Anti-money-laundering compliance

A day before, state regulators separately ordered Block to pay $80 million over violations of Bank Secrecy Act and anti-money-laundering rules. That’s a different matter from the CFPB order, so the two amounts shouldn’t be added together as one settlement.

Lending risk

Borrow is the engine of growth, but it carries real credit risk. Block says its loss rates have stayed low, and it has chartered its own bank so it doesn’t have to rely only on partner banks. But a small-dollar lender that grows loan originations 59% in a year is a company that has to keep proving its underwriting. A downturn that hits paychecks hits Borrow first.

There’s a plain takeaway for anyone building in this space. Compliance, fraud tooling and support are not things you add later. Instead, for a money app they’re part of the product, and they show up in the cost line. Our banking and finance page explains how we approach that.

Cash App vs Venmo vs Zelle: three different ways to make money

People compare these three as if they were the same product with different logos. They’re not, and the business models are the clearest way to see it.

	Cash App	Venmo	Zelle
Owned by	Block	PayPal	Early Warning Services, a company owned by major US banks
Core idea	A full financial app built around a balance and card	Social payments that grew into a wallet and card	Bank-to-bank transfers inside your existing banking app
Where the money comes from	Instant transfers, card swipe fees, lending, BNPL, bitcoin, business fees	Instant transfers, business payments, card interchange, crypto fees (see our Venmo breakdown)	Little direct revenue. Banks use it to keep customers (see our Zelle breakdown)
Lending	Yes, a major driver	Not a core business	No

The pattern, in short: Zelle is a feature that protects a bank. Meanwhile, Venmo is a social network that learned to monetize payments. Cash App is the most aggressive of the three at turning the payment relationship into an entire financial relationship, which is also why it carries the most risk.

Five myths about how Cash App makes money

After reading enough forum threads and half-right explainers, a few wrong ideas keep coming up. Here’s each one, and what the numbers actually say.

Myth 1: “Cash App earns its money from sending payments.”

It doesn’t. Sending from a bank account or debit card is free, and that’s most of what people do on the app. Instead, the money comes from the things around it: cashing out fast, spending on the card, borrowing, and buying later.

Myth 2: “Bitcoin is the big money-maker.”

Bitcoin is the big revenue line. As we saw, $1.89 billion of revenue turned into $72 million of gross profit in the quarter. For comparison, Cash App’s overall gross profit was $1.97 billion. Bitcoin matters for attracting and keeping users. It doesn’t pay the bills.

Myth 3: “More users automatically means more profit.”

Not here. Monthly users grew 3% in the latest quarter while gross profit grew 31%. Instead, the growth came from earning more per customer, not from adding customers. That’s a different business to run, and a riskier one if the extra earnings depend on lending.

Myth 4: “Cash App is basically a bank.”

It looks like one and behaves like one in a lot of ways, but Block says plainly that Cash App is a financial services platform and that its banking services run through partner banks. Also, the distinction affects who regulates what, and who holds your money.

Myth 5: “Free means there’s no catch.”

There’s no catch in sending $20 to a friend. But the app is built to move you along: faster transfers cost something, the card earns on your spending, and Borrow charges a flat fee. None of that is hidden. The fees are published, and the app shows the fee before you confirm. It’s still worth knowing which of your habits are the ones paying for the free ones.

What founders can learn from Cash App

You don’t need 59 million users to use this playbook. Instead, you need to understand the shape of it. Here’s what we’d take away if we were advising a team starting a payments product tomorrow.

1. Give away the thing everybody wants

Free transfers get people in the door. Charging for them would otherwise have killed the growth that everything else depends on.

2. Charge for speed, not for access

Instant transfers are the clearest example. Nobody feels cheated by paying to go faster. But they’d feel cheated by paying to join.

3. Make the default path profitable

The card, direct deposit and in-app spending are the free options Cash App wants you to choose, and they’re also the ones that earn interchange. Design your fee structure so that the easy choice is also the profitable one.

4. Use your own data to underwrite

Borrow works because Cash App can see paycheck deposits and spending. Data from your own product beats a generic credit file for the right customers. It also means you have to earn that data first.

5. Measure gross profit, not revenue

Bitcoin showed why. If your product passes money through, then revenue will flatter you. Track what’s left after the direct costs.

6. Budget for compliance from day one

The $175 million CFPB order and the $80 million state action are what the cost of treating compliance as an afterthought looks like. It’s cheaper to build the controls early.

What it takes to build a Cash App-style product

Here’s where we should be straight with you. The screens in an app like this are the easy part. Any decent mobile team can build a clean send-money flow, a transaction history and a card screen. But what decides whether the product ever launches is everything underneath.

Start with one wedge, not the whole app

Cash App didn’t launch with loans and bitcoin. It launched with sending money. Pick the one job your first users hire you for (splitting rent, paying freelancers, remittances to one country) and do it better than the alternatives. Add the profitable layers later.

The ledger is the heart

Every balance, every transfer, every fee has to be recorded in a way that adds up, every time, even when a payment fails halfway. A proper double-entry ledger isn’t glamorous, but a bug here is a financial bug, not a UI bug. Get this reviewed by someone who has built one before. If you don’t have that person in-house, then a dedicated development team is one way to add them.

Partners you plug in

Almost no startup holds money on its own balance sheet on day one. So you’ll typically work with a sponsor or partner bank, a card issuing and processing partner, an identity-verification (KYC) provider, and, for lending or crypto, credit-data and exchange partners. Also, many of these connections run through APIs between fintechs and banks. Choosing the partners is a product decision, because they set your fees, your limits and your launch timeline.

Compliance and fraud aren’t phase two

Depending on where you operate, you’ll need money-transmitter licences or a partner that holds them, anti-money-laundering (AML) and sanctions screening, PCI DSS for card data, and a clear process for disputes and unauthorised transactions. The Cash App enforcement actions above are the cautionary tale. Build monitoring, limits and a support process into the first release, and test every money flow before launch with proper quality engineering.

Add monetization in the order users earn it

The Cash App staircase works because each step follows naturally from the last. Free transfers, then a balance, then a card, then direct deposit, then credit. If you try to launch lending before people trust you with their paycheck, you’ll have nobody eligible to lend to.

Stage	What you launch	How it earns
1. Acquire	Free peer-to-peer payments	Nothing yet. Growth and trust.
2. Retain	Balance, instant transfer	Fees on speed
3. Engage	Debit card, direct deposit	Interchange
4. Deepen	Savings, bill pay, rewards	Interchange, partner fees
5. Lend	Small loans, buy now pay later	Loan fees, merchant fees

Frequently asked questions about how Cash App makes money

The bottom line: how does Cash App make money?

Cash App is a free app for sending money that earns billions by being useful in the dozen ways you need money between payday and the next payday. Instant transfers charge for speed. The card earns on spending. Afterpay and Cash App Pay, meanwhile, earn from merchants. Borrow earns on the gap between paychecks. Bitcoin brings people in at razor-thin margins. And the 59 million users aren’t growing much, but each one is worth more every quarter.

It’s a smart model. It’s also a hard one to copy, because the part you see (the app) is the small part. The parts you don’t see, however, are the licences, partners, ledger and risk model. And launch is only the start, because fees, limits and partner connections need ongoing product maintenance.

If you’re thinking about building something in this space, start small, get one job right, and plan the staircase with a clear product roadmap before you build the first stair.
