Commercial Bank Credit Card Interest Rate

Primary source

All values come directly from Federal Reserve G.19 via FRED (TERMCBCCALLNS). We do not modify, smooth, or interpolate published values.

The average interest rate on credit card plans at commercial banks, all accounts. Published quarterly by the Federal Reserve in the G.19 Consumer Credit release. Key input for credit card payoff planning and balance transfer decisions.

Update schedule

Quarterly — we refresh daily; upstream publishes four times per year.

We gate dateModified updates to actual value changes (threshold: 0.01% absolute or 0.5% relative) to prevent freshness spoofing. If the upstream value hasn't moved, we don't claim we updated the page.
