How Do Neobanks Actually Make Money?

If neobanks don't charge monthly fees, don't have branches, and offer free ATM withdrawals, how do they make money? It's a question we hear constantly, and the answer reveals the fundamental difference between traditional and digital banking business models.

The short answer is that somebody else is paying — usually merchants, sometimes the central bank, and increasingly you, in a way that is not itemised as a fee. Here are the five revenue lines behind the neobanks we track, and then the one regulatory quirk that explains why American and European neobanks behave so differently.

The revenue streams

Interchange — the merchant pays for your free account

Every card payment carries a fee paid by the merchant, and a share flows back to the card issuer. Multiply a small amount by every coffee, weekly shop and subscription across millions of customers and it becomes the foundation of the free-account model.

This is why every free banking app pushes so hard to become your primary spending card and to receive your salary. A customer who parks £50 and never uses the card is a pure cost.

Premium subscriptions — small share of users, large share of profit

Paid tiers — metal cards, travel insurance, higher allowances, lounge access — cost very little more to serve than free ones, so the margin is high. N26's plans, for instance, run from a free Standard to Metal at €16.90 a month. A minority of customers upgrading is enough to matter, because almost all of that revenue drops through.

Net interest income — the line that quietly changed everything

A neobank holding your balance earns a return on it, and pays you less than it earns. That spread is the net interest margin, and when policy rates rose from near zero it turned from a rounding error into the largest profit line at several of these companies.

It is also the honest answer to "why does my account pay no interest?" The balance sitting there is the product.

Lending — where the real money is, and the real risk

Personal loans, credit cards, overdrafts and buy-now-pay-later generate the highest margins of anything on this list. Lending is also the only line that can lose money in size: interchange revenue cannot go negative, and a loan book can. This is why a young neobank's growth in lending is watched more closely by investors than its growth in customers.

Partner commissions and marketplaces

Insurance, investments, savings from third parties, mortgages and currency services referred to partners, all paying a commission. Marketplace models — Starling's being the well-known example — turn the app into a distribution channel for other people's products.

The regulatory quirk that explains almost everything

Interchange is capped very differently on each side of the Atlantic, and this single fact explains most of the strategic difference between US and European neobanks.

In the EU and UK, the Interchange Fee Regulation caps consumer card interchange at 0.2% for debit and 0.3% for credit. That is deliberately low, and it means a European neobank cannot fund itself on card fees alone. So European challengers monetise through subscriptions, foreign exchange and lending — which is exactly what Revolut, N26 and Monzo do.

In the United States, the Durbin amendment caps debit interchange — but exempts banks with under $10 billion in assets. A fintech partnered with a small bank therefore earns several times more per debit swipe than a large bank does on the same transaction.

That exemption is the economic engine of US neobanking. It explains why so many American fintechs partner with small, unfamiliar banks rather than large ones, why the free-account model works there and not in Europe, and why direct deposit is the single metric those companies optimise for. It is also why the partner-bank structure — with all the consequences set out in embedded finance — is so common in the US and comparatively rare in Europe.

Are neobanks profitable?

Several of the largest reached profitability, and the sector's path is typically long — often the better part of a decade — because acquiring customers costs money immediately while lending and deposit revenue arrive later.

Two things are worth separating when you read a profitability headline:

• Profitable overall is not profitable per customer. A company can be in profit because a minority of engaged customers subsidise a long tail of dormant ones.

• Rate-driven profit is not the same as durable profit. A great deal of recent profitability across the sector came from higher policy rates lifting net interest income. That is real money, and it is not evidence that the underlying model works at low rates.

What this means for you

• The free account is paid for by merchants, so expect pressure to make it your main card. If it suits you, that trade is fine.

• Your balance is revenue. If you keep meaningful savings there, compare what you are being paid against what is available elsewhere — see best high-yield savings accounts.

• Read the premium tier as a product, not a loyalty reward. Price the perks you would actually use against the annual cost.

• Free FX usually has an allowance. The allowance is where the model pays for itself; the cost begins where it ends. Wise vs Revolut for transfers covers how that works in practice.

• Watch the licence. A US provider earning enhanced interchange is doing so via a partner bank, which changes who holds your deposit — see the neobank safety guide.

The bottom line

The model is genuinely better aligned than fee-heavy traditional banking: a neobank mostly earns when you use it, not when you slip up. That is a real improvement and worth saying plainly.

But "free" is a pricing decision, not a gift. The revenue comes from merchant fees on your spending, the spread on your balance, and interest on what you borrow. Knowing which of those you personally supply tells you exactly how good a deal you are getting.
