Variable Interest Rate Definition
Variable interest rate is an amount on top of a given loan or security. It changes over time because it is based on a standard interest rate that changes from time to time. For example, if you borrow a loan from a bank, and the standard rate decrease, the interest at which you borrowed loan at also decrease. But, if the benchmark interest rate increases, the rate at which you borrowed a loan also increases. Generally, the variable interest rate works best for banks. For instance, if you borrow money from a bank at a variable interest rate of seven percent with an additional index rate which might be five percent. Therefore, one will pay the loan with an interest rate of 12%. However, if the index rate appreciates from five percent to let's say seven percent, then the interest on the loaned amount becomes fourteen percent as a result.
