Index
An index is a benchmark rate, such as the prime rate or LIBOR, to which a margin is applied to calculate a variable interest rate. For example, if your credit card agreement says your interest rate is prime plus 10 percent, and the prime rate is at 5 percent, your credit card's interest rate will be 15 percent.
