The average credit card now charges 20.94 percent across all accounts, and 22.15 percent on accounts that carry a balance. Those are second-quarter 2026 figures from the Federal Reserve’s G.19 consumer credit release. Only a slice of that rate comes from the Fed.
The bottom line: your card rate is a moving benchmark plus a fixed markup, and the Fed controls only the benchmark.
The chain from the Fed to your statement
The Fed does not set card rates. It sets a target range for the federal funds rate, the overnight rate banks charge one another. Banks then post the prime rate by convention: the top of that range plus 3 percentage points. In July the range stood at 3.50 to 3.75 percent, so prime sat at 6.75 percent, where it had been since December.
Your card agreement adds a margin on top of prime. On the average account that margin works out to roughly 14 points, and it depends on your credit profile and the card. Prime floats. The margin mostly stays put.
Markets had priced about an 87 percent chance of a hold at the July 29 meeting. Then came September 16, when the Fed raised its target range by a quarter point, to 3.75 to 4 percent. By the same convention, prime moves to 7.00 percent.
Why your APR may not budge the same day
Banks lift prime within a day of a Fed move. Issuers typically pass the change to variable accounts within one or two billing cycles. But two cycles is not a rule. Card agreements differ: one filed with the Consumer Financial Protection Bureau reads the prime rate shortly before the statement closes and applies the new APR at the start of the relevant cycle, while another uses a different number of business days before closing. Some customers see a change quickly, and others wait.
The statement date can matter more than the meeting date. The place to check is the cardholder agreement, which spells out the index, the margin and the timing. Issuers are slower in the other direction, too. Rate hikes reach cardholders fast, and cuts can take much longer to trickle down.
One rule surprises people. The Credit CARD Act of 2009 and Regulation Z require 45 days of notice before most rate increases, but not when the increase comes from a change in the index. Prime is that index, so a Fed-driven rise can hit an existing balance and new purchases with no separate warning letter. It simply shows up on the next statement. A card can also carry different rates for purchases, balance transfers and cash advances, and promotional rates follow their own terms.
What a quarter point costs
Not much per move. A quarter-point increase adds about $2.08 a month, or roughly $25 a year, for every $10,000 you carry from cycle to cycle. Two hikes would double that.
The base rate does the real damage. At 20.94 percent, a $6,000 balance carried for a year costs well over $1,200 in interest.
