Floor

An interest rate floor is set by the issuer of a variable rate credit card as the minimum annual percentage rate it will charge. Usually, variable credit card interest rates are pegged to the prime rate, which moves up and down in accord with the federal funds rate set by the Federal Reserve. However, when the Fed cuts rates severely, cards with floors will not pass those rate cuts along.
