Learn How American Express Credit Cards Work

Understanding How American Express Credit Cards Function

American Express, commonly called Amex, operates as both a credit card company and a payment processor. Unlike most credit card issuers that partner with Visa or Mastercard networks, American Express runs its own payment system. This means when you use an American Express card, the transaction flows directly through American Express rather than through a separate network.

American Express cards work on a charge-pay model, though this has evolved over the decades. Historically, American Express required cardholders to pay their full balance monthly, making it different from traditional revolving credit cards. Today, most American Express cards function similarly to standard credit cards—you can carry a balance and pay interest on what you owe, or you can pay in full each month to avoid interest charges.

The company issues several card types, each designed for different spending patterns and financial situations. These range from basic cards for building credit history to premium cards with annual fees that offer extensive rewards programs and travel perks. Understanding the structure of your specific card type helps you maximize its features and avoid unexpected costs.

American Express generates revenue through three main channels: annual fees charged to cardholders, interest payments on carried balances, and merchant fees. When a store accepts your American Express card, they pay a processing fee to American Express—typically higher than Visa or Mastercard fees. This is one reason some smaller merchants don't accept American Express. The company uses this revenue to fund rewards programs, customer service, and fraud protection.

Practical takeaway: Before obtaining an American Express card, verify that the merchants you frequent accept American Express. While acceptance is widespread among major retailers and restaurants, smaller independent businesses may not participate in the American Express network. Checking acceptance rates in your area prevents card activation disappointments.

The Application Process and Card Approval Timeline

When you decide to pursue an American Express card, you'll begin by providing personal financial information. The company uses this data to assess creditworthiness. American Express reviews your credit score, credit history, income, employment status, and existing debts. These factors help American Express determine whether to issue you a card and what credit limit to offer.

The approval decision typically comes within seconds or minutes for online submissions. American Express uses automated systems that instantly review your information against their lending criteria. Some applications may be flagged for manual review, which can take several business days. If American Express needs clarification about your financial situation, they may contact you by phone or email.

Your credit score significantly influences approval odds. American Express generally prefers applicants with credit scores of 670 or higher, though some cards may be available to those with lower scores. The company also examines your payment history—they want to see that you've paid previous obligations on time. Recent negative items like late payments, collections, or bankruptcy filings can result in denial.

Income requirements vary by card type. American Express publishes that some cards require minimum annual incomes ranging from $25,000 to over $250,000, depending on the card's tier. However, the company considers household income, which may include spousal earnings, investment income, or retirement benefits. There's no official minimum income for basic American Express cards, though the company does verify that your stated income is reasonable.

The approval process also includes fraud prevention screening. American Express verifies that you're the person submitting the information by checking identification details against databases. If something seems suspicious—such as an application from an unusual geographic location or multiple applications in a short timeframe—American Express may deny the application or request additional verification.

Practical takeaway: Gather your recent financial documents before submitting an American Express application. Having your Social Security number, current income figures, employment information, and housing costs readily available speeds up the process. If denied, you can typically reapply after addressing the specific reason for denial, such as building your credit score or reducing existing debt.

How Credit Limits Work and What They Mean

Your credit limit represents the maximum amount American Express will allow you to charge on your card during a billing period. When you receive approval, American Express assigns an initial credit limit based on your creditworthiness and income. These limits typically range from $1,000 for new cardholders with limited credit history to $25,000 or more for established cardholders with excellent credit.

The credit limit functions as a safety mechanism for both you and American Express. For American Express, it manages their risk by capping exposure to any single cardholder. For you, it prevents overspending beyond what the company has determined you can reasonably manage. Your credit limit doesn't change automatically based on spending—it remains fixed unless you request an increase or American Express adjusts it based on account performance.

Several factors influence the credit limit amount you receive. Your credit score is primary—higher scores typically receive higher limits. Income level also matters significantly; American Express assumes higher-income individuals can manage larger balances. Your employment stability and length of time with current employment also factor into calculations. Additionally, American Express considers your existing debt levels. Someone carrying $50,000 in other debt won't receive as high a limit as someone carrying minimal debt, even with the same credit score.

You can request credit limit increases through the American Express website or by calling customer service. These requests may be reviewed with or without a hard credit inquiry. A soft inquiry doesn't affect your credit score and is used when American Express reviews your existing account history. A hard inquiry pulls your full credit report and may slightly reduce your credit score temporarily. American Express generally considers limit increase requests favorably if your account shows good payment history over several months.

Important to understand: your credit limit and available credit are different. Your available credit is your limit minus your current balance. If you have a $5,000 limit and currently carry a $2,000 balance, you have $3,000 in available credit. As you pay down your balance, your available credit increases. This available credit is what matters when making purchases—if you try to charge beyond your available credit, the transaction will be declined.

Practical takeaway: Monitor your credit utilization—the percentage of your limit you're using. Keeping your balance below 30% of your limit helps maintain good credit scores. For example, with a $5,000 limit, keeping your balance under $1,500 positively impacts your credit. This demonstrates responsible credit management to potential lenders and credit bureaus.

Understanding Billing Cycles and Payment Requirements

American Express operates on a monthly billing cycle. Your billing cycle typically lasts about 30 days and runs on a date assigned to your account—for example, the 5th through the 5th of the following month, or the 15th through the 15th. During your billing cycle, all purchases you make are recorded. At the end of the cycle, American Express generates your monthly statement showing everything you charged.

Your statement includes several important dates. The statement closing date marks the end of your billing period—this is when American Express finalizes what you owe. The due date typically falls about 21 days after the closing date, giving you time to pay. The payment due date is critical; making at least the minimum payment by this date keeps your account in good standing. Payments made after the due date are considered late and can trigger fees and credit score damage.

American Express requires a minimum payment each month when you carry a balance. This minimum is typically calculated as either a fixed percentage of your balance or a small fixed dollar amount plus interest and fees—whichever is higher. For example, if your balance is $2,000 and the minimum payment percentage is 1%, your minimum payment would be at least $20, plus any interest charges that have accumulated. Making only the minimum payment means you're paying mostly interest and very little toward your principal balance, so your debt decreases slowly.

Understanding interest works is essential. If you pay your full statement balance by the due date, you pay zero interest. American Express offers an interest-free grace period from the statement closing date until the due date. However, if you carry any balance into the next month, interest accrues on that balance from the purchase date forward—there's no grace period for new purchases once you're carrying a balance. Interest rates on American Express cards vary by card type and your creditworthiness, typically ranging from 16% to 26% annually.

Your statement also shows fees you may have incurred. Annual fees, if applicable to your card type, appear once yearly. Late payment fees typically range from $25 to $39 for first offenses. Foreign transaction fees, usually 2-3%, appear if you made purchases in foreign currencies. Other fees might include over-limit fees if you exceeded your credit limit,
