American Express Credit Card Minimum Payment: How It's Calculated
American Express has a more complex product structure than most US issuers because of its mix of traditional charge cards (pay in full, no revolving balance) and revolving credit cards. Understanding which type your Amex card is, and which of its programs apply, is the first step before calculating any minimum payment. We are not affiliated with American Express.
Updated May 2026 · Per Regulation Z all consumer credit card minimum-payment formulas are disclosed in the cardmember agreement; this page is a methodology guide, not a substitute.
Section I · Charge Card vs Revolving Card
The single most important distinction within the Amex portfolio
Amex historically built its brand around charge cards (the original Green, Gold, and Platinum products), which require payment of the full statement balance every month and do not carry a revolving balance with monthly minimum payments. This is a fundamentally different product structure from a traditional revolving credit card, where you can carry a balance and pay a monthly minimum at an APR.
Amex has expanded its product portfolio in two directions over the past two decades. First, it added traditional revolving credit cards (Blue Cash, EveryDay, Cash Magnet, plus a wide co-branded portfolio with Delta, Hilton, Marriott Bonvoy, and others), which behave like other major-issuer credit cards: revolving balance, monthly minimum payment, APR. Second, it added Pay Over Time as an opt-in feature on many charge cards, allowing eligible charges (typically over $100) to be moved to a revolving balance with a monthly minimum and an APR.
Which structure applies to your Amex card is disclosed in your cardmember agreement and visible on your monthly statement. If your statement shows a "Minimum Payment Due" line and a "Minimum Payment Warning" box, you are looking at a revolving balance subject to standard credit-card minimum-payment math. If your statement shows only "Please Pay By" with the full balance, you are looking at a charge card without a Pay Over Time balance.
Section II · Where Amex Publishes Formulas
The cardmember agreement is the only authoritative source
For revolving Amex consumer credit cards, the minimum-payment formula is in the Cardmember Agreement available as a PDF in your Amex online account under the card's account services. Amex also publishes agreements at americanexpress.com/us/credit-cards/cardmember-agreement.
Amex's revolving consumer card minimum-payment formulas, per agreements published at the disclosure site, sit within the same industry tiers as other major US bank issuers: either a flat percentage of balance (typically 1% to 2%) or interest plus 1% of principal, with a $25 to $40 floor. The exact percentage, floor, and treatment of fees varies by individual card product. For a $5,000 balance at the 2026 average APR of 22%, an Amex card using the interest-plus-1% formula would produce a first-month minimum near $142.
For Pay Over Time programs on charge cards, the program-specific terms (the minimum payment formula, the APR, eligibility rules for which charges can be moved to revolving) are in the Pay Over Time program disclosure that comes with the underlying charge card agreement. Same authority structure: the disclosure document is the only binding source.
Section III · Verifying Your Number
Three places to cross-check the Amex minimum-payment math
- The cardmember agreement. The legally binding source. Open the PDF, find the minimum-payment section, read the formula. The agreement also discloses the floor amount, late-fee schedule, penalty APR triggers (if applicable), and grace-period rules. Worth a careful one-time read.
- The Minimum Payment Warning box on every monthly statement. Federal regulation, codified at 12 CFR Section 1026.7(b)(12), requires this box on every revolving credit card statement. Cross-check the alternate 36-month payment against the calculator on the homepage; the numbers should match within a few dollars.
- The Schumer Box at card application. Required on every credit card application under 12 CFR Part 1026 Subpart B. Discloses APR ranges, fees, and grace-period terms. The minimum-payment formula itself is in the longer cardmember agreement.
Section IV · The Amex Card Universe
Where to find the right document for your specific Amex product
Amex's consumer card portfolio includes the charge cards (Green, Gold, Platinum, Centurion), the revolving credit cards (Blue Cash Everyday, Blue Cash Preferred, EveryDay, Cash Magnet), and a large co-branded portfolio (Delta SkyMiles family, Hilton Honors family, Marriott Bonvoy family, Schwab Investor Card, plus retail and travel partners). Each card has its own cardmember agreement.
For an existing cardholder, the fastest route is to log in to your Amex online account, navigate to the card detail page, and download the cardmember agreement PDF. The agreement is typically 10 to 18 pages and the minimum-payment section is usually near the front under "How We Calculate Your Minimum Payment". Pay Over Time program terms, if applicable, are in a separate program disclosure linked from the same account services area.
For new applicants, the Schumer Box on each application page shows the APR ranges, fees, and grace-period terms. The full agreement is delivered with the physical card or via email shortly after approval.
Section V · Worked Math at Common Balances
What Amex-style minimum-payment math produces at common balances
Using the industry-standard interest-plus-1% formula at the 2026 average APR of 22%, with a typical $25 floor, the first-month minimum payments at common balances on a revolving Amex card would be: $1,000 → about $28, $2,500 → about $71, $5,000 → about $142, $10,000 → about $283, $15,000 → about $425. These are illustrative figures using the industry-tier formula; verify your specific Amex card's terms in your cardmember agreement.
