How Fintech Companies Make Money

Start with the financial activity, not the app

A fintech company may look like a bank on a phone, a checkout button or a budgeting dashboard. Its economics depend on what happens underneath: moving money, extending credit, managing investments or selling software to other businesses.

“Fintech” is not a regulatory licence or a single business model. A company might hold a banking licence, operate as a payment institution, distribute products supplied by regulated partners, or provide technology without handling customer funds.

To understand how it makes money, ask three questions:

• Who pays? The customer, a merchant, a financial institution or another business?
• What triggers revenue? A transaction, subscription, outstanding loan or asset balance?
• What must the company pay out? Processing costs, partner fees, funding costs, losses and compliance expenses?

Customer balances and transaction volumes are not revenue. A profitable-looking fee can also conceal substantial costs.

1. Payments and card revenue

Merchant fees and processing charges

When a merchant accepts an electronic payment, it usually pays a payment provider. Charges may include a transaction percentage, a fixed processing fee and fees for services such as fraud screening or currency conversion.

The provider does not necessarily retain the whole amount. In a typical card payment, the merchant service charge helps cover:

• Interchange paid to the card issuer.
• Card-network fees.
• Acquiring and processing costs.
• The payment provider’s own margin.

A fintech can earn more by supplying additional services, such as reconciliation software, subscription billing or dispute management. These services can generate recurring revenue alongside transaction fees.

Payment volume alone says little about profitability. A provider processing large payments at a thin margin may retain less than one serving a smaller, more specialised customer base.

Interchange for card issuers

A fintech offering debit or credit cards may receive interchange directly as an issuer or share it with a licensed issuing partner. The merchant funds this indirectly through its acceptance charges.

Interchange income helps explain why some accounts offer free everyday spending. But it must support costs such as card production, fraud losses, customer service and any rewards.

Rules differ materially. The EU and UK cap interchange for specified categories of consumer card transactions. US debit-card rules distinguish between covered issuers and exempt institutions. Card type, issuer status and transaction geography affect the economics; one country’s model should not be assumed to work elsewhere.

2. Subscriptions and service fees

Subscriptions turn occasional usage into recurring revenue. Individuals may pay for additional account features, budgeting tools or investment services. Businesses may pay for expense management, invoicing, payroll integrations or multi-user controls.

Other charges are usage-based: cash withdrawals, expedited transfers, replacement cards or transactions above an included allowance.

The commercial calculation is straightforward: recurring income must exceed the cost of providing the package and attracting and retaining its users. Benefits such as insurance or airport access are not free to the provider; they involve supplier contracts and eligibility conditions.

For readers comparing products, the useful measure is the total cost of their expected usage, not simply the headline monthly fee. Check whether a paid plan reduces other charges or merely bundles features that would otherwise go unused.

3. Lending and credit

Interest income and funding costs

A lender earns interest on outstanding credit. Its funding might come from deposits, institutional borrowing, investors or securitisation structures that finance pools of loans.

The difference between interest earned and funding costs is only the starting point. Lending income must also cover:

• Borrower defaults and recoveries.
• Underwriting and servicing.
• Fraud and collections.
• Regulatory compliance and, where applicable, capital requirements.

A high lending rate therefore does not automatically mean a high profit margin. Expensive funding or weak repayment performance can consume the apparent spread.

Some fintechs originate loans for partner lenders rather than keeping them on their own balance sheets. They may receive origination or servicing fees. Contracts determine whether they also retain credit exposure or obligations to repurchase certain loans.

Buy now, pay later

Buy now, pay later providers often charge merchants for offering instalments at checkout. Merchants accept that cost in the hope of improving sales or order completion.

Depending on the product and local law, borrowers may also pay interest or permitted fees. An interest-free offer for the shopper is not necessarily a revenue-free transaction for the provider.

The provider still needs to fund the purchase and manage defaults, fraud, refunds and disputes. Consumer-credit treatment varies and continues to evolve, so local regulatory guidance matters.

4. Foreign exchange and international transfers

Cross-border providers commonly earn revenue through a transfer fee, a foreign-exchange margin or both.

The margin is the difference between the exchange rate offered to the customer and the provider’s relevant reference or execution rate. A transfer advertised without a separate fee can still generate revenue through that margin.

Behind the interface, the provider may use local bank accounts and payment systems to collect money in one country and pay it out in another. This can reduce reliance on a separate international bank transfer for every customer instruction. It does not eliminate liquidity, settlement or compliance costs.

Profit depends on payment-rail charges, banking partners, currency hedging and maintaining funds where payouts are needed. Compare the amount ultimately received, as well as timing and any intermediary charges.

5. Investment and wealth services

Investment platforms can combine several revenue sources:

• Asset-based fees: charges linked to the value of assets managed or administered.
• Dealing fees: charges for executing transactions.
• Subscriptions: payments for tools, research or additional functionality.
• Currency conversion: charges when investments settle in another currency.
• Securities lending: income from lending eligible securities under the applicable arrangements.

Some also receive revenue connected with customers’ uninvested cash. The amount retained depends on the account structure, interest paid to customers and payments to banking or custody partners.

“Commission-free” describes one charge, not the entire business model. Order-routing payments are restricted or prohibited in some jurisdictions and permitted subject to requirements in others. Execution, custody and conflicts-of-interest disclosures explain more than the marketing label.

6. Financial software, infrastructure and referrals

Many fintechs sell to businesses rather than consumers. Customers may buy identity verification, fraud detection, payment connectivity, regulatory reporting or account infrastructure through application programming interfaces, or APIs.

Revenue can come from implementation fees, monthly minimums, per-check charges or usage-based contracts. A software provider can earn money without holding customer funds, although outsourcing, security and data-protection requirements still matter.

Banking-as-a-service arrangements combine technology with regulated banking or payment services. Revenue is divided among the platform, licensed institution and sometimes other intermediaries. The customer-facing company may retain only part of the overall fee.

Referral models are different again. An app may receive a commission when a user opens a partner account, buys insurance or takes a loan. This creates potential conflicts: the product paying the largest commission is not necessarily the best match for the user. Clear disclosures should distinguish paid distribution from independent comparison.

7. Interest on balances and digital-money reserves

Holding funds can generate income, but the legal structure determines what is permitted and who receives it.

A bank generally records customer deposits as liabilities and uses its balance sheet to make loans and hold investments, subject to prudential and liquidity rules.

A payment or electronic-money institution is different. It generally must safeguard relevant customer funds rather than treat them as unrestricted funding for its own lending. Permitted safeguarding arrangements may generate interest, but whether the firm can retain it depends on law, contracts and the arrangement used.

Some stablecoin issuers similarly seek income from permitted reserve assets. That income must support custody, liquidity management, redemption and compliance. Reserve assets are backing obligations, not freely available profit.

In the EU, MiCA imposes distinct requirements on asset-referenced and e-money tokens, including restrictions on granting interest. Readers should not assume that holding a payment token creates an entitlement to reserve income or bank-deposit protection.

How regulation shapes the business model

Licensing determines which activities a fintech can perform itself and which need a regulated partner.

European Union and United Kingdom

The EU’s PSD2 and EMD2 frameworks distinguish payment institutions and electronic-money institutions from banks. MiCA provides a separate framework for relevant cryptoassets and service providers. Legislative changes and national implementation should be checked with the relevant authority.

In the UK, check the FCA register for the precise entity and permissions; deposit-taking also involves prudential authorisation. Funds held as payment or e-money balances are generally safeguarded rather than protected as bank deposits under the Financial Services Compensation Scheme. Safeguarding is not an equivalent guarantee of immediate repayment.

United States

A fintech may combine state money-transmitter licences, lending permissions and bank partnerships. Federal and state requirements depend on the activity.

A non-bank app is not itself FDIC-insured. Eligible deposits placed at an insured partner bank may qualify for pass-through coverage if applicable conditions are met. This does not insure the fintech against business failure or guarantee uninterrupted access.

Switzerland, UAE and Singapore

Switzerland distinguishes banking authorisation from FINMA’s more limited FinTech licence. The latter is not a general permission to use public deposits for lending or to pay interest on them.

In the UAE, the applicable authority depends on the activity and location. The Central Bank regulates important banking and payment activities, while financial free zones and virtual-asset activities can involve other regulators.

Singapore’s Payment Services Act establishes licensing categories for specified payment services. A payment licence is not a banking licence. Check MAS guidance for the relevant activity, restrictions and customer-money requirements.

Revenue is not profit

A durable fintech must cover more than its visible transaction costs. Customer acquisition, engineering, cybersecurity, complaints, regulatory reporting and partner oversight all consume revenue.

Three distinctions make any model easier to assess:

• Gross versus retained revenue: how much passes to networks, banks and other partners?
• Recurring versus variable income: does revenue depend on subscriptions, spending, borrowing or interest rates?
• Fee income versus risk-taking: is the company selling a service, or earning a return for accepting credit, liquidity or market risk?

The clearest business models make these flows understandable. Follow the money from the payer through the intermediaries, identify the obligations attached to customer funds, and examine the costs and risks left with the fintech.
