Most credit cards in the United States carry a variable APR, which means the rate you pay is tied to a benchmark, usually the Prime Rate. The Prime Rate follows the Federal Reserve’s target for the federal funds rate, so a decision made in Washington can show up on your statement a month or two later. This guide explains that chain, shows what current data says about card rates, and puts numbers on what a change costs. For the most recent decision, see our article on the Fed’s September rate increase.
Where card rates stand now
According to the Federal Reserve’s G.19 Consumer Credit report, the average APR on credit card accounts that were assessed interest was 22.15% in the second quarter of 2026, up from 21.52% in the first quarter. Across all accounts, including those that do not carry a balance, the average stated APR was 20.94%. Balances are large as well: the New York Fed reported that credit card balances reached $1.263 trillion at the end of June 2026, up $21 billion in the quarter. These figures predate the Fed’s September 16 rate increase, so they do not yet reflect it.
How a Fed decision becomes your APR
- The Fed sets a target range for the federal funds rate, the rate banks charge each other for overnight loans. On September 16, 2026, the range moved to 3.75% to 4.00%.
- Banks set the Prime Rate in response, typically about three percentage points above the top of that range. A 4.00% upper bound therefore points to a Prime Rate of about 7%.
- Card issuers price a variable APR as the Prime Rate plus a margin that depends on your credit profile and the card. When Prime moves, your APR moves by the same amount, usually within one or two billing cycles.
- Fixed-rate cards and promotional 0% offers generally do not change with Prime. A promotional rate ends on the date in your agreement, and the standard rate that follows is usually variable.
What a rate change costs, in dollars
The extra interest is simple arithmetic: the balance multiplied by the change in APR, if you carry that balance for a full year. The table shows the added annual interest at three balances.
| Balance carried all year | APR up 0.25 point | APR up 0.50 point | APR up 1.00 point |
|---|---|---|---|
| $2,000 | $5.00 | $10.00 | $20.00 |
| $5,000 | $12.50 | $25.00 | $50.00 |
| $10,000 | $25.00 | $50.00 | $100.00 |
A quarter-point move looks small, and for a single increase it is. The cost builds when several increases arrive in a row or when a balance sits for years, which is why the average APR for accounts paying interest matters more than any single decision.
Why your APR can differ from the averages
The G.19 figure is an average across banks. Your own APR depends on your credit profile, the type of card, and the margin your issuer set when you opened the account. Averages also blend very different products, from premium rewards cards to store cards. Treat the number as a benchmark for comparison, not as a prediction of your rate.
What to do when rates rise
- Check the APR on your latest statement and compare it with your cardholder agreement to see which index your card follows.
- Pay down the balance with the highest APR first, while making at least the minimum payment on the others.
- If you carry a balance, compare 0% balance transfer offers, and weigh the transfer fee (commonly 3% to 5%) against the interest you would save.
- Avoid adding new purchases to a card that carries a balance, since you typically lose the interest-free grace period on new purchases when you do not pay in full.
Bottom line
Fed decisions reach your card through a short and predictable chain: the federal funds target, then the Prime Rate, then your variable APR. You cannot control the Fed, but you can control the size of the balance that carries the rate. Knowing where your own APR comes from, and what each quarter point costs, turns a news headline into a number you can plan around.
