How American Express Makes its Money: Revenue Breakdown (2024)

How Does American Express Make its Money?

American Express Company (NYSE: AXP) generated $65.9 billion in total revenue in fiscal year 2024 — up +8.9% from $60.5 billion in 2023 — driven by $1.55 trillion in cardholder spending on its network, 15% growth in card fee revenue, and a premium card strategy that has consistently attracted higher-spending customers than any competing card issuer. Net income reached $10.1 billion (15.3% net margin), return on equity was approximately 33%, and the company raised its dividend for the fourth consecutive year.

American Express is structurally different from every other major card company. Visa and Mastercard are payment networks — they process transactions between bank card issuers and merchants, collecting a small network fee, but they never own the customer relationship, never extend credit, and never take credit risk. American Express is a closed-loop integrated payments company: it simultaneously operates the card network, issues cards directly to consumers and businesses, extends credit, and owns the merchant acquiring relationship. This means Amex collects revenue at three points in every transaction — a merchant discount fee when the purchase is made, a card fee from the cardholder annually, and interest income if the cardholder carries a balance. Visa and Mastercard collect only the network fee.

This closed-loop model was invented by American Express in 1958 when it issued its first charge card — a green cardboard card that required full payment monthly, with no preset spending limit, targeted at business travelers who needed a trusted payment credential when traveling away from home. The model has evolved dramatically over 65+ years but the core logic persists: by owning the full relationship, Amex can offer premium cardholders richer rewards, exclusive experiences, and superior customer service than any bank-issued Visa or Mastercard can match, because Amex captures more revenue per transaction and therefore has more economics to reinvest in the cardholder value proposition.

Under CEO Stephen Squeri (CEO since 2018), American Express has successfully repositioned from a card brand associated with affluent Baby Boomers to a premium card brand genuinely adopted by Millennials and Gen Z — over 60% of new Platinum Card members in 2024 were Millennials or Gen Z. This demographic shift, combined with the secular growth of card spending globally and the ongoing expansion of Amex’s merchant acceptance network (now essentially universal in the U.S.), positions Amex as both a durable franchise and a meaningful growth story.

Key Takeaways

• $65.9B in total revenue (+8.9% YoY) — consistent high-single-digit revenue growth has been a hallmark of Amex’s post-pandemic expansion; from 2021 through 2024, Amex has compounded revenue at approximately 17% annually as pandemic-suppressed travel and dining spending recovered and then grew; the +8.9% growth in 2024 represents a normalization to a more sustainable pace but remains well above Visa’s (+10% constant currency) and Mastercard’s (+11%) overall revenue growth rates when adjusted for their different revenue recognition models; Amex’s revenue growth is direct volume growth while Visa/Mastercard report net revenue after rebates to issuing banks
• $1.55 trillion in billed business — total spending by Amex cardholders on Amex-branded cards globally; this is the fundamental volume driver for the entire business; $1.55T grew approximately +6% in 2024; Amex cardholders spend on average 3–4x more per card per year than holders of Visa or Mastercard consumer credit cards — a function of Amex’s premium customer base (higher income, higher spending propensity) and the rewards structure (generous rewards on spending incentivize using the card for more categories); the $1.55T base at a blended discount rate of approximately 2.35% generates the $36.3B in discount revenue that is Amex’s largest single revenue stream
• Net card fees of $8.4B (+15.1%) — the fastest-growing major revenue line; annual card fees (Platinum Card at $695/year, Gold Card at $325/year, Green Card at $150/year, Delta Reserve at $650/year, and dozens of co-brand variations) grew 15% as new card acquisitions exceeded card cancellations and as Amex raised fees on flagship products while adding new benefits to justify the increases; card fee revenue is essentially pure gross profit — once the card is issued, there is no marginal cost to collect the annual fee; growth in this line signals the health of Amex’s premium brand positioning and its ability to retain cardholders who are paying increasingly large annual fees
• Net income of $10.1B (+20.2% YoY) — net income growth of +20% on +9% revenue growth demonstrates operating leverage and below-revenue-growth credit loss provisions; the difference is explained by efficient expense management and the premium credit quality of Amex’s cardholders (who default at materially lower rates than mass-market credit card borrowers)
• Return on equity of ~33% — exceptional for a financial services company of this size; Visa’s ROE is ~35–40% but Visa takes no credit risk and is capital-light; Amex’s 33% ROE while carrying a $130B+ loan portfolio (with associated credit risk and capital requirements) reflects the pricing power and spending volume of its premium cardholder base; JPMorgan Chase’s ROE is approximately 17%; Capital One’s is approximately 12%; Amex’s ROE is structurally higher because its customers generate more revenue per dollar of credit extended
• Younger cardholder mix accelerating — over 60% of new Platinum Card members and Gold Card members in 2024 were Millennials or Gen Z; this demographic achievement is critical for Amex’s 20–30 year growth outlook; a 28-year-old who becomes an Amex Platinum member in 2024 represents potentially 40+ years of growing card spending as income rises, career advances, and family spending grows; the conventional wisdom that premium credit cards were exclusively for established professionals has been disrupted by social media marketing (the “unboxing” culture around Amex Platinum) and by the genuine value of travel benefits for younger high-earning professionals
• Merchant acceptance now near-universal in the U.S. — historically, Amex’s higher merchant fees meant many small businesses refused to accept it, limiting cardholder utility; through renegotiated acceptance agreements, OptBlue (a program allowing small merchants to accept Amex through their payment processor at competitive rates), and years of acceptance expansion, Amex now achieves ~99% U.S. merchant acceptance; this removes the primary practical objection to carrying an Amex card and is a prerequisite for the Gen Z acquisition strategy to succeed (a 28-year-old won’t carry a card they can’t use everywhere)

American Express (AXP) Business Model

American Express operates through the Transaction Fee Business Model and the Spread-Based Business Model simultaneously — a unique dual-engine revenue structure within the Financial Services sector.

The closed-loop advantage explained:

In an open-loop network (Visa or Mastercard), four parties participate in every transaction:

1. The cardholder (e.g., Chase Sapphire cardholder)
2. The issuing bank (Chase, which issued the card, extends credit, and collects most of the merchant fee)
3. The card network (Visa, which processes the transaction and collects ~0.10–0.15% network fee)
4. The merchant’s bank / acquirer (e.g., Square, Stripe — collects a small acquiring fee)

In Amex’s closed-loop model, Amex simultaneously plays the role of issuing bank, card network, and historically its own acquirer — collecting the full merchant discount (2.35% average blended rate) rather than just the network fee. The “discount” flows to Amex, which then uses it to fund rewards, benefits, and the cost of cardholder acquisition — rather than splitting it among banks as open-loop networks must.

Revenue per transaction comparison:

Amex’s higher merchant discount (~2.35% blended vs. ~1.8–2.0% for premium Visa/Mastercard) is justified to merchants because Amex cardholders have measurably higher average transaction values and higher annual spending. A restaurant that accepts Amex pays a higher merchant fee but its Amex customers spend more per meal and tip more generously on average — the incremental merchant fee is offset by incremental revenue from premium spenders.

The rewards flywheel:

More discount revenue → More money to fund rich rewards → Better rewards attract higher-spending cardholders → Higher cardholder spending generates more discount revenue → Repeat. This self-reinforcing dynamic is why Amex’s market position has proven durable against Visa/Mastercard premium products (Chase Sapphire Reserve, Capital One Venture X) that attempt to replicate Amex’s rewards richness — those products are funded by a portion of the network fee that flows to the issuing bank, which is structurally smaller than Amex’s full discount capture.

The three-revenue-stream model:

Amex generates revenue at three points in the customer lifecycle:

1. Acquisition: (no direct revenue) — customer acquisition costs are a marketing expense
2. Card fee: collected annually (Platinum $695, Gold $325, etc.) — high margin revenue
3. Transaction: 2.35% of every purchase made on the card — discount revenue
4. Carry: if the cardholder carries a balance (rather than paying in full), interest income at rates typically 20–29% APR — net interest income

Most Amex cardholders generate all three ongoing revenue streams (annual fee + transaction + some carry); the premium customer base generates significantly more per cardholder than comparable open-loop card holders because of higher spending volumes, willingness to pay premium annual fees, and (increasingly) revolving balance behavior among younger cardholders building credit.

American Express Competitors

American Express competes across several intersecting competitive dimensions:

Card network competition:

• Visa and Mastercard — the duopoly that controls open-loop payment network infrastructure globally; Visa and Mastercard don’t compete with Amex as card issuers (they partner with banks who issue the cards), but they do compete indirectly because premium bank-issued Visa/Mastercard products (Chase Sapphire, Capital One Venture X) compete for the same premium cardholder wallet; see Visa vs Mastercard for the network-level comparison

Premium credit card competition:

• JPMorgan Chase (Chase Sapphire Reserve) — the most direct competitive product to Amex Platinum; Chase Sapphire Reserve ($550/year fee) offers Priority Pass airport lounge access, 3x points on travel and dining, and transferable Ultimate Rewards points; it directly targets the affluent traveler that Amex Platinum targets; Chase’s advantage is universal acceptance (issued on Visa network) and the absence of Amex’s premium merchant fee; Amex’s advantage is richer specific benefits (Centurion lounges, Fine Hotels & Resorts, dining credits) and the brand prestige that Amex has built over 65+ years; see JPMorgan vs Bank of America for broader banking competitive context
• Capital One (Venture X) — the newest entrant in the ultra-premium card segment ($395/year), targeting younger affluent consumers with simple 2x miles on all spending and airport lounge access; Capital One’s marketing is aggressive and has demonstrated success in capturing Millennial consideration; the simpler earn-everywhere structure appeals to cardholders who find Amex’s category-based rewards complex

Co-brand card competition:

• Major airlines (Delta, United, Southwest) and hotels (Marriott, Hilton) issue co-branded cards on both Visa/Mastercard networks (through Chase and others) and the Amex network; Delta exclusively with Amex (SkyMiles cards are Amex-only), which is a significant competitive differentiator — Delta’s loyalty program and Amex’s card program have a deeply intertwined co-brand relationship that generates hundreds of millions in Delta SkyMiles purchases annually

Revenue Breakdown

Financial data sourced from American Express 2024 Annual Report (10-K).

Discount Revenue — 55% of Total

Discount revenue of $36.3 billion is generated when merchants pay Amex a percentage of each purchase made by Amex cardholders at their businesses. The average blended discount rate is approximately 2.35% — the highest in the industry, justified by the premium spending characteristics of Amex cardholders. The discount rate varies by merchant category (higher for travel and restaurants, lower for large retail and grocery) and by merchant size (large merchants negotiate lower rates).

Billed business volume drives discount revenue:

The U.S. Consumer and Small Business segments are the core — together accounting for approximately 63% of billed business. Small Business (Amex OPEN) is a particularly important segment: American Express has historically had the strongest relationships with small business owners among all card issuers, offering corporate cards, expense management tools, and working capital solutions. Small business cardholders tend to have higher discount rates (smaller merchants negotiate less) and higher annual card fees (business cards carry premium fees).

Net Card Fees — 13% of Total, Fastest-Growing Line

Card fee revenue of $8.4 billion growing +15.1% is the clearest indicator of Amex’s brand strength and cardholder value proposition health. Card fees are earned when Amex collects the annual membership fee from each cardholder — a fee that is deferred and recognized ratably over the card year. If a Platinum cardholder pays $695 in February, Amex recognizes approximately $58/month in card fee revenue for 12 months.

Why 15% growth is remarkable: Card fee growth = (net new card adds) × (average fee per new card) + (fee increases on existing cards) - (cancellations × lost fee). Growing at 15% requires either adding many new premium cards, successfully raising fees without proportional cancellation increases, or both. Amex has achieved both: it added millions of new cards (particularly international) and raised fees (Platinum went from $550 to $695 over several years) while demonstrating that cardholders continue to value the benefits sufficiently to maintain cards despite the higher cost.

Net Interest Income — 21% of Total

Interest income of $14.2 billion comes from Amex cardholders who carry revolving balances — i.e., who do not pay their statement in full each month and are therefore charged interest on the outstanding balance. Amex’s net interest income is after subtracting the cost of funding (interest paid on deposits and debt used to fund the loan portfolio).

American Express has historically positioned as a “pay-in-full” or “charge card” company — the original charge card required full monthly payment. Today, many Amex products (particularly consumer credit cards like Gold and Blue Cash) allow revolving balances. The loan portfolio has grown as younger cardholders (who are more comfortable carrying balances than older cohorts) increasingly adopt Amex products. Rising interest rates from 2022–2024 benefited net interest income as Amex’s variable-rate receivables repriced upward while some funding costs lagged.

Other Revenue — 11% of Total

Other revenue of $7.0 billion (+8.1%) includes:

• Amex Travel — travel booking commissions, hotel program revenue, cruise bookings; Amex Travel is the third-largest U.S. travel agency by volume; Platinum and Centurion cardholders frequently book through Amex to access guaranteed rates and dedicated travel consultants
• Foreign exchange revenue — fees on international transactions when currency conversion occurs
• Insurance — travel insurance and purchase protection products sold to cardholders
• Miscellaneous fees — late fees, cash advance fees, other card-related fees

American Express (AXP) Income Statement

Card Member Rewards ($17.2B) is the largest single expense — Amex spends more on cardholder rewards than on salaries, marketing, or credit losses combined; this is the direct cost of the rewards flywheel; Amex’s rewards expense as a percentage of discount revenue is approximately 47% (every $100 of discount revenue generates ~$47 in rewards cost); this rewards cost is structurally embedded in the business model — it is what makes the premium cardholder experience possible and what differentiates Amex from lower-margin card products; rewards cost growing +10.7% (slightly above discount revenue growth of +10.0%) reflects a modest increase in rewards richness/redemption rates.

Provision for Credit Losses ($5.3B, +4.3%) — credit loss provisions grew modestly below revenue growth, confirming that Amex’s premium cardholder base maintains credit quality even as the loan portfolio grows; compare to mass-market credit card issuers (Capital One, Synchrony) where provision growth often runs at or above revenue growth during normal periods; Amex’s below-revenue provision growth rate is a direct consequence of the income demographics of its cardholder base — higher-income cardholders default at substantially lower rates.

EPS grew +25.0% — faster than net income (+20.6%) due to share buybacks reducing diluted share count; Amex has been consistently repurchasing shares, which mechanically amplifies EPS growth relative to net income growth.

American Express (AXP) Key Financial Metrics

• Gross Margin on Discount Revenue: ~53% — after card member rewards of ~$17B, discount revenue gross profit is approximately $19B on $36.3B of discount revenue; this is the relevant profitability metric for the core transaction business; the remaining gross profit funds all other operating expenses and profit

• Operating Margin — Amex doesn’t report operating margin in a traditional sense due to financial services accounting, but pre-provision operating income (revenue minus operating expenses before credit loss provision) implies strong operating efficiency; pre-tax income margin of 20.0% ($13.2B on $65.9B) is exceptional for a company carrying full credit risk

• Return on Equity: ~33% — one of the highest ROEs among large financial services companies; Amex’s ROE is structurally elevated because its premium cardholder base generates high revenue per dollar of credit extended, its closed-loop model captures more revenue per transaction than open-loop competitors, and its capital requirements (while material due to the loan book) are lower than commercial banks that hold illiquid loans

• Free Cash Flow — Amex generated approximately $9–10B in free cash flow in 2024, deployed primarily into share buybacks (~$6.7B in 2024) and dividends ($1.7B), with excess retained for loan portfolio growth; the FCF yield to shareholders (buybacks + dividends as % of market cap) was approximately 4–5% at year-end 2024 prices

• Net Write-Off Rate: ~2.2% — the percentage of the outstanding loan portfolio written off as uncollectable annually; this is meaningfully below the industry average for credit card issuers (~3.0–3.5% for mass-market issuers) and reflects the income composition of Amex’s cardholders; Amex targets affluent and mass-affluent consumers whose debt-to-income ratios and emergency fund reserves provide substantially better credit resilience than average

• Card Member Acquisition: 13M+ new cards in 2024 — a record; new card acquisitions demonstrate that the premium card value proposition continues to attract new customers despite annual fee levels that have risen 25–30% over five years; acquisition is particularly strong internationally (markets like India, Mexico, and the UK) and among younger demographics in the U.S.

The Delta Co-Brand Partnership

One of American Express’s most strategic relationships is its exclusive co-brand partnership with Delta Air Lines — one of the most valuable co-brand agreements in the U.S. credit card industry. Delta SkyMiles American Express cards are issued exclusively by Amex on its network; there are no Delta Visa or Delta Mastercard products.

The economics: Amex pays Delta for SkyMiles (miles that Amex awards to cardholders as rewards), typically at $0.010–0.012 per mile. When Amex cardholders redeem miles for Delta flights, the airline has already been paid. Delta disclosed in 2020 that it receives approximately $3–4 billion annually from Amex through this partnership — making Amex one of Delta’s largest revenue sources. In return, Amex gets exclusive marketing rights at Delta gates, co-marketing in Delta emails, preferred boarding privileges for Delta Amex cardholders, and access to Delta’s loyal customer base as prospects for Amex card acquisition.

The Delta partnership is a significant competitive moat: it took decades to build, cannot be easily replicated by Visa or Mastercard without a competing airline relationship, and creates a flywheel where Delta’s most loyal customers (who fly most frequently) are also the highest-spending Amex cardholders.

Is American Express Profitable?

Yes. American Express generated $10.1 billion in net income on $65.9 billion in revenue in fiscal year 2024 — a 15.4% net margin — and approximately $9–10 billion in free cash flow. Return on equity of approximately 33% is among the highest in financial services at this scale. EPS of $14.01 grew +25.0% year-over-year, supported by share count reduction through buybacks. Amex has been consistently profitable for decades and significantly increased profitability post-pandemic as travel and dining spending recovered and as the premium card strategy generated operating leverage.

What to Watch

1. Billed business growth trajectory — the single most important leading indicator; discount revenue (55% of total) is directly proportional to billed business; watch quarterly billed business growth rate (has been +6–8% in 2024) versus management guidance of mid-single-digit growth; any acceleration above +8% suggests ARPU growth or premium customer spending strength; deceleration below +4% signals macro pressure on consumer spending

2. Card fee revenue sustainability at 15%+ growth — the 15.1% growth rate in 2024 reflects strong new card acquisitions and fee increases; this rate is unlikely to sustain perpetually; watch whether growth decelerates toward 8–10% as the Millennial/Gen Z acquisition wave matures; card fee revenue growth above 10% for multiple years is a signal that Amex has permanently expanded its premium cardholder base

3. Gen Z retention through the economic cycle — Amex has successfully acquired Gen Z premium cardholders, but this cohort has never experienced a severe recession as Amex cardholders; watch write-off rate trends specifically for new/younger cardholders; a spike in write-offs for recent vintages would signal that the Gen Z acquisition strategy is attracting cardholders with less credit resilience than Amex’s historical profile

4. Net interest income and credit loss rates — with a growing revolving loan portfolio, credit quality is increasingly important; watch the net write-off rate (currently ~2.2%) for any upward trend; if consumer financial stress builds, Amex’s premium cardholder base provides a buffer but is not immune; provisions growing faster than revenue would signal deteriorating credit conditions

5. International expansion progress — Amex is underpenetrated internationally vs. Visa and Mastercard, which have effectively universal global acceptance; Amex is investing in acceptance expansion in India, Latin America, and Southeast Asia; watch international billed business growth (which has been growing faster than U.S. at +7–9%) as a signal of the international opportunity realizing; each 1 percentage point of international card fee and discount revenue growth represents a significant revenue contribution over time

6. Competition from Chase Sapphire and Capital One Venture X — the premium card competitive set has intensified since 2016 (Chase Sapphire Reserve launch) and 2021 (Capital One Venture X); watch Amex’s new card acquisition costs, cancel rates on Platinum and Gold, and whether Amex needs to increase benefits spending to remain competitive; the rewards expense growing faster than discount revenue (as in 2024: +10.7% vs +10.0%) is an early warning sign to monitor

American Express (AXP) Financial Summary

American Express Company (NYSE: AXP) generated $65.9 billion in total revenue (+9.5%) in fiscal year 2024, with net income of $10.1 billion (+20.6%) and diluted EPS of $14.01 (+25.0%). The closed-loop payment network model — collecting merchant discount revenue (~2.35% on $1.55 trillion in billed business), card membership fees ($8.4B, +15.1%), and net interest income ($14.2B) simultaneously — produces a return on equity of approximately 33% that is exceptional among financial services companies at this scale. The strategic pillars — premium cardholder brand, exclusive Delta co-brand partnership, 99% U.S. merchant acceptance, and successful Millennial/Gen Z acquisition — sustain a competitive position that has proven durable against open-loop network competitors for over 65 years. Key risks: macroeconomic deceleration compressing consumer spending, credit quality deterioration in younger cardholder cohorts, and sustained competitive intensity from Chase Sapphire and Capital One Venture X.
