How Credit Card Issuers Make Money on $0-Annual-Fee Cards

The recurring question from cardholders new to no-annual-fee cards: if Wells Fargo and Capital One and Discover give me a card with no annual fee, no monthly fee, and pay me 1.5-2% cash back on everything, how do they make money? The answer is that issuers have five major revenue streams, only one of which (annual fees) is removed when you hold a no-AF card. The others continue, and together they are far more lucrative than the annual fees from premium cards. Below: the math of the credit card business, with data from the Federal Reserve and the Nilson Report.

Revenue Stream 1: Interchange (The Big One)

Every time you swipe, tap, or use a credit card online, the merchant pays a fee called interchange to your card's issuing bank. Interchange is the largest single revenue stream in the credit card business, the engine that makes no-AF cards economically viable.

Typical US credit card interchange rates:

  • Visa/Mastercard standard credit card: 1.5-2.5% of transaction value plus a per-transaction fee of $0.10-$0.15
  • Visa/Mastercard rewards card: 2-2.5%, slightly higher than standard
  • Visa Signature/World Mastercard (mid-tier): 2.3-2.8%
  • Visa Infinite/World Elite (premium): 2.5-3.0%
  • American Express (proprietary card): 2.5-3.5%, historically higher than Visa/Mastercard

Per the Federal Reserve's biennial Regulation II report on payment card interchange, US merchants paid $172 billion in interchange fees in 2023, with credit card interchange representing roughly $130 billion of that. The Nilson Report's 2024 industry totals showed US credit cards processed approximately $5.5 trillion in purchase volume in 2024.

The math from the issuer's perspective: a household spending $30,000 per year on a no-AF rewards card generates roughly $600-$750 in interchange revenue (2-2.5% blended rate). The issuer pays the cardholder back about $450-$600 in cash back rewards (1.5-2%). Net interchange margin: $150-$250 per cardholder per year. Multiply by tens of millions of cardholders.

Revenue Stream 2: Interest on Revolving Balances

For the roughly 47% of US credit card accounts that carry a balance month-to-month (Fed G.19 data), interest income is the issuer's second-largest revenue stream and possibly the most profitable single component.

The Federal Reserve's G.19 Consumer Credit report as of late 2024 showed roughly $1.2 trillion of revolving credit card debt outstanding, at an average APR on accounts assessed interest of around 22-23%.

Rough math: $1.2 trillion of revolving debt at 22% APR generates roughly $264 billion in interest income per year for the credit card industry. After deducting funding costs (issuers borrow at lower rates and lend at credit card rates; the spread is the profit), the net interest margin is enormous.

From the issuer's perspective, the dynamics:

  • Cardholders who pay in full each month generate interchange but no interest. Issuers earn maybe $150-$250/year net on these "transactors."
  • Cardholders who carry a balance generate interchange PLUS interest. A cardholder with a $5,000 average balance at 22% generates $1,100/year in interest alone, plus interchange. Net contribution: $1,200-$1,400/year.
  • Revolvers are roughly 5-10x more profitable than transactors per cardholder.

This is why issuers happily offer no-AF rewards cards to high-credit-score applicants: a percentage of them will eventually carry a balance during a life event (job loss, medical bill, divorce, home repair), at which point that cardholder becomes hugely profitable. The economics work out even if 80% of cardholders never carry a balance, because the 20% who do generate enough revenue to cover the whole portfolio.

Revenue Stream 3: Late Fees, Cash Advance Fees, FX Fees

The miscellaneous fees that get less attention than interest and interchange add up to a substantial revenue stream. The CFPB estimated total US credit card late fees alone at approximately $14 billion per year as of 2023, the figure that motivated the CFPB's 2024 rule capping late fees at $8 (currently in litigation; see our late fees page).

Other fee streams:

  • Cash advance fees: 3-5% of cash advanced, minimum $10. Combined with the elevated cash-advance APR (typically 27-30%), the cash-advance product is one of the highest-margin offerings for issuers. Estimated industry-wide revenue: $4-$6 billion/year.
  • Balance transfer fees: 3-5% of transfer amount. Charged on the receiving card. Industry-wide revenue: $3-$5 billion/year.
  • Foreign transaction fees: 1-3% on foreign-currency transactions. Industry-wide revenue: $2-$4 billion/year.
  • Returned payment fees: Up to $40 per returned payment (e.g. bounced check or ACH return). Modest in total but pure margin.
  • Over-limit fees: Largely eliminated by CARD Act 2009 opt-in requirements but still exist for cardholders who opt in to over-limit transactions.

Combined miscellaneous fee revenue across the US credit card industry: roughly $25-$30 billion per year. A meaningful share, even if dwarfed by interest and interchange.

Revenue Stream 4: Co-Brand Partnership Revenue

Many no-AF cards are co-brands. The Chase Freedom Unlimited shares branding with Chase Travel and Doordash. The Amex Blue Cash Everyday is tied to Amex Offers. The Discover it integrates with Discover Deals. These co-brand relationships generate revenue for the issuer beyond what you see on the card.

How co-brand economics work:

  • The partnered merchant (e.g. Doordash for Chase's DashPass benefit) pays the issuer for cardholder access. The issuer typically receives a per-cardholder annual fee from the merchant for the audience.
  • The issuer's shopping portal (Chase Shop Through Chase, Amex Offers Shopping) generates affiliate revenue from merchants. Merchants pay the issuer a percentage of cardholder spending routed through the portal.
  • Loyalty programme integrations (United MileagePlus on the Chase Sapphire line, Delta SkyMiles on Amex cards) involve large cash payments from the airline to the issuer for the right to be the "default" transfer programme.
  • Banking-on relationships: many credit card customers also open checking, savings, mortgage, or investment products with the same bank. The cross-sell economics make the credit card portfolio a customer acquisition tool for higher-margin products.

Revenue Stream 5: Card-Linked Offers and Data

The newest and fastest-growing revenue stream. Issuers monetise the transaction-level data they collect through targeted offers, attribution networks, and merchant analytics.

How it works:

  • Issuer aggregates cardholder spending data (anonymised and de-identified at the merchant level, but rich with category, time, geography, and amount detail).
  • Merchants pay issuers to push targeted offers to cardholders likely to spend at the merchant. Amex Offers, Chase Offers, Capital One Offers, Discover Deals all operate this way.
  • Merchants pay issuers to measure ad campaign effectiveness through card-linked attribution. If a merchant ran a Facebook ad campaign and wants to know which ad caused which cardholder to swipe at the merchant, the issuer's data can answer that.
  • Anonymised aggregate data is sold to investment banks, hedge funds, and consumer-trends researchers for billions per year industry-wide.

This is the newest revenue stream and the one that most concerns privacy advocates. The data is legally permitted under the cardholder agreement you accepted at signup. The aggregate revenue from these activities is estimated at $5-$10 billion/year across the US credit card industry as of 2024 and growing.

Why Issue No-Annual-Fee Cards At All?

The strategic logic from the issuer perspective:

  1. Customer acquisition. A no-AF card is the lowest-friction way to acquire a cardholder. Once acquired, the customer has lifetime value: years of interchange, possible future balance carrying, cross-sell potential into mortgage or banking products.
  2. Portfolio diversification. Issuers want a mix of customer types. High-end premium cardholders are valuable but volatile (they switch frequently for sign-up bonuses). No-AF cardholders are sticky; they rarely close cards because there is no recurring fee to evaluate.
  3. Defensive product. If Chase did not offer a Freedom Unlimited, customers shopping for a no-AF card would go to Citi or Capital One. Holding the no-AF customer in the Chase ecosystem prevents them from forming a relationship with a competing issuer.
  4. Upsell funnel. A cardholder who opens a Chase Freedom Unlimited and uses it for 2-3 years is a prime candidate to upgrade to a Sapphire Preferred ($95 AF) later, especially after marketing nudges. The Freedom Unlimited is essentially a prospecting tool for the Sapphire customer base.
  5. Risk learning. Issuers use the no-AF cardholder relationship to learn the customer's payment behaviour, credit usage, and risk profile. That data informs future credit limit increases, product offerings, and (occasionally) the decision to extend a larger loan product like a home equity line.

FAQ

How does my credit card company make money on a no-annual-fee card?
Five revenue streams: interchange fees from merchants (1.5-3% of every transaction you make), interest on revolving balances if you carry one (around 22-23% APR average per Federal Reserve G.19 data), miscellaneous fees (late fees, cash advance fees, foreign transaction fees, returned payment fees), co-brand partnership revenue, and the sale of anonymised transaction data. Of these, interchange and interest are by far the largest. Annual fees are a meaningful revenue stream for premium cards but represent a small share of total industry profit. As of 2026-05-15.
What is interchange?
A fee paid by merchants to credit card issuing banks each time a credit card is used at the merchant's point of sale (in-person or online). Interchange rates in the US run 1.5-3% of transaction value plus a small per-transaction fee. Visa and Mastercard set the rates; the rates flow from merchant to acquirer to network to issuer. Interchange is the single largest revenue stream in the US credit card business, generating roughly $130 billion per year across all credit cards.
Why is interest so much higher on credit cards than on other loans?
Credit cards are unsecured (no collateral backing the loan), can be drawn at will (creating uncertain cash flow for the issuer), and have higher default rates than secured loans. The credit card APR has to cover defaults, operational costs, capital requirements, and profit margin. Even at 22% APR, credit card portfolios' net return on assets after defaults and costs is competitive with but not dramatically higher than other consumer lending. The headline rate hides the loss rates.
Do credit card companies want me to carry a balance?
Yes, from a profitability perspective. A cardholder who pays in full each month generates interchange but no interest. A cardholder carrying a balance generates interchange PLUS interest income, making them 5-10x more profitable per year. That said, issuers also want responsible borrowers; they do not want defaults. The sweet spot for issuers is borrowers with high credit scores who occasionally carry balances (e.g. during life events) but reliably pay them down. Aspirational marketing tends to target this customer profile.
Are credit card companies selling my data?
Aggregated and anonymised transaction data is sold by issuers to investment researchers, market analysts, and hedge funds, generating roughly $5-$10 billion/year industry-wide. The data is typically de-identified at the cardholder level (no "Jane Doe" transactions identified) but rich with merchant, category, time, and amount detail. The sales are legal under the cardholder agreement you accept at signup. Individual cardholders generally cannot opt out of this aggregation, though card-linked offer programmes (Amex Offers, etc.) sometimes can be opted out of in account settings.
Why do issuers offer such generous welcome bonuses?
Customer acquisition cost in financial services is high; a $200-$1,000 welcome bonus is cheap compared to traditional marketing channels for the customer lifetime value generated. A cardholder acquired with a $500 welcome bonus who then spends $30K/year for 10 years generates $30K-$50K in interchange and (if they carry balances) potentially $50K-$100K in interest income. The welcome bonus is excellent ROI even after subtracting churners who close cards after capturing the bonus.
Are co-brand cards (like the Amazon Prime Visa) more profitable for issuers?
Co-brand cards are typically less profitable per cardholder for the issuer than proprietary cards, because the merchant partner takes a share of the economics. Chase shares interchange revenue with Amazon on the Amazon Prime Visa. United pays Chase to be the airline partner on the Sapphire line. The co-brand structure trades issuer margin for customer acquisition (the merchant's marketing channel brings cardholders the issuer might not reach independently). The economics work out for both sides because the marketing leverage and lifetime customer value are strong.
