How American Express Company Makes Money

While Visa and Mastercard operate as open-loop networks — earning thin transaction fees while leaving the actual card issuance and consumer credit risk to banks — American Express functions as both the network and the bank simultaneously. In FY2024, card fee revenues reached 8.0 billion dollars, a 18 percent increase year-over-year, reflecting the company's successful strategy of packaging card benefits so richly that the annual fee itself feels like a bargain to the target customer. The Consumer Financial Protection Bureau has intensified scrutiny of credit card late fees. The company's competitive differentiation rests on its ability to attract high-spending, affluent cardholders, charge premium annual fees, and extract superior merchant discount rates by delivering higher-value customers to merchants. The irony is, unlike Visa and Mastercard, which function as pure network intermediaries and earn thin per-transaction fees while banks bear the credit risk and customer relationships, American Express is vertically integrated. Discount revenue — the merchant fees collected on card transactions — remained the single largest revenue line, generating approximately 25.1 billion dollars in 2024. Net card fees represented the fastest-growing and strategically most important revenue stream, reaching 8.0 billion dollars in FY2024, an 18 percent increase from the prior year. American Express has systematically invested in card benefits — particularly for its premium Platinum and Centurion products — to make annual fees feel like exceptional value to high-income consumers. The Platinum Card's 695-dollar annual fee, for instance, comes bundled with 200 dollars in airline fee credits, 200 dollars in hotel credits through Fine Hotels + Resorts, access to over 1,400 airport lounges globally through the Centurion Lounge and Priority Pass networks, 240 dollars in digital entertainment credits, and a suite of travel and lifestyle perquisites. For a frequent traveler, these benefits demonstrably exceed the fee cost, creating a rational economic case for card renewal that drives exceptional retention rates. In fact, service fees and other revenue — encompassing travel services, foreign exchange margins, loyalty redemption economics, and fee income from various ancillary products — added several billion dollars more to the revenue mix, completing a diversified income architecture that reduces dependence on any single line. The company makes money every time a card member swipes, earns more when card members carry balances, collects a growing stream of annual fees for membership privileges, and compounds all of these streams on top of a customer base that self-selects for wealth, travel intensity, and spending ambition. Its discount revenue per dollar of billed business exceeds that of Visa or Mastercard, its card fee revenue per card is multiples of what any bank issuing a Visa or Mastercard product earns in net interchange, and its write-off rates are structurally lower due to its affluent cardholder base. The Sapphire Reserve card, introduced at a 550-dollar annual fee with a 300-dollar travel credit and Priority Pass lounge access, attracted enormous market attention and temporarily put American Express on the defensive. Rather than competing on price or reducing its annual fees, the company doubled down on benefits enhancement. Card fee revenue of 8.0 billion dollars was the standout growth metric, growing 18 percent year-over-year and reflecting the company's successful strategy of enriching card benefits sufficiently to justify sustained premium pricing. Regulatory pressure on credit card fees represents another material headwind. The Consumer Financial Protection Bureau, under various administrations, has scrutinized late fees, foreign transaction fees, and balance transfer fees across the credit card industry. While American Express's affluent card member base results in relatively low late-fee revenue concentration compared to mass-market issuers, any broad regulatory caps on card fees would disproportionately affect the premium pricing architecture that supports the company's economics. American Express's most durable competitive advantage is its closed-loop network architecture, which creates structural information asymmetries and pricing power unavailable to its principal competitors. The affluent cardholder base creates a virtuous cycle: premium card members attract premium merchants eager to reach high-spending customers; premium merchant acceptance makes the card more valuable to premium card members; premium card member spending generates sufficient fee income to fund premium benefits; and premium benefits attract more affluent card members.

It issues the cards, underwrites the credit, acquires the merchant relationships, and owns every data point in the transaction chain. And global merchant acceptance, long a weakness for the American Express network, remains an ongoing investment priority. Net interest income — the spread earned on revolving credit card balances — contributed approximately 14.0 billion dollars in FY2024, reflecting the company's growing credit card portfolio as it expanded beyond its traditional charge-card roots. In FY2024, this cost line approached 15 billion dollars, reflecting the company's significant investment in its Membership Rewards program, co-branded card partnerships with Delta Air Lines, Hilton Hotels, Marriott, and others, and the direct cost of Centurion Lounge operations. Marketing and business development expenses represent another substantial cost, typically running 4 to 5 billion dollars annually as American Express continuously invests in acquiring new card members, particularly younger demographics who represent the company's long-term growth engine. ICS, serving card members outside the United States, was the segment with the most geographic growth runway, particularly in markets like India, Mexico, Australia, and the United Kingdom where affluent consumer segments are expanding rapidly. Points can be transferred to over 20 airline and hotel partners at attractive ratios, used to book travel through the American Express Travel portal, or redeemed for statement credits and merchandise. Surprisingly, when interest rates rose in 2022 through 2024, net interest income expanded to offset any compression in merchant fee growth. The Platinum Card was progressively enriched with new credits, new lounge access tiers, and expanded lifestyle benefits. And critically, American Express accelerated investment in its own Centurion Lounge network, opening new locations in major U.S. Airports to provide a proprietary lounge experience that no Priority Pass competitor could replicate — because Priority Pass lounges are shared infrastructure, while Centurion Lounges are exclusively American Express. The strategy worked. American Express's premium card acquisition accelerated post-2020, with the company adding over 12 million new cards in several consecutive years. The new cohorts skewed younger — millennials and Gen Z now represent over 60 percent of new consumer card acquisitions — and their spending behavior has proven more resilient and more digitally engaged than older cohorts, validating the investment in next-generation card member acquisition. American Express has responded by investing heavily in its own mobile application, which now allows card members to manage rewards, browse and book travel, access card benefits, and communicate with customer service in a unified digital environment. Perhaps the most underappreciated dimension of the competitive landscape is American Express's growing role as a small business financial services platform. Revenue growth of approximately 9 percent year-over-year was driven by three converging forces: the continued expansion of card fee income as premium card adoption accelerated, growth in net interest income as the revolving credit portfolio matured, and steady increases in discount revenue as billed business grew in both consumer and commercial segments. Operating expense growth was held below revenue growth, producing positive operating use and driving return on equity above 32 percent. The most immediate competitive threat comes from the accelerating adoption of buy-now-pay-later products — led by companies like Affirm, Klarna, and Afterpay — among younger consumers who represent American Express's most critical growth demographic. Here's why: while American Express has introduced its own Plan It installment feature, the structural economics of BNPL differ from traditional revolving credit in ways that compress interest income, a growing revenue contributor for the company. Despite decades of investment, American Express is still not accepted at every merchant that accepts Visa and Mastercard. Apple's expanding financial services footprint presents perhaps the longest-term structural challenge. American Express's growth strategy under CEO Stephen Squeri rests on four mutually reinforcing pillars that collectively aim to sustain the revenue and earnings growth rates achieved between 2022 and 2024 across a full economic cycle. American Express has accelerated investment in digital acquisition channels, social media marketing, and campus ambassador programs to intercept younger consumers at formative stages of their financial journeys. The second pillar is expanding the core offering of existing card relationships by continuously enriching benefits, adding new merchant partnerships, and deepening digital engagement through the American Express application and network. The company has systematically added dining, entertainment, and lifestyle credits to its premium cards to make them relevant to urban professionals who may not travel frequently enough to justify a travel-focused card on that basis alone. The fourth pillar is international revenue growth, with particular focus on markets where premium card penetration remains nascent relative to the size of the addressable affluent population. American Express has been investing in local merchant acquisition, co-branded card partnerships with regional airlines and hotels, and digital marketing capabilities in priority international markets to accelerate what has historically been a slower-growing segment of the business. The company's most important near-term growth driver is the continued maturation of its younger card member cohorts. Millennials and Gen Z card members acquired over the past five years have spending trajectories that historically increase substantially as cardholders age into peak earning years. International expansion represents the most underpenetrated long-term growth opportunity. Markets like India — where a rapidly expanding middle and upper-middle class, combined with government-promoted digital payments infrastructure, creates a natural addressable market for premium card products — represent decade-long growth opportunities. Wells operated Wells & Company; Fargo ran Livingston, Fargo & Company with partner Johnston Livingston. A third major player, John Butterfield, operated Butterfield & Wasson, focused primarily on upstate New York routes. Wells and Fargo had both hoped to expand their express business westward to serve the California gold rush markets — a vast, rapidly growing opportunity created by the 1848 discovery of gold at Sutter's Mill.
