Interest Rate Calculator

Our interest rate calculator works backwards from a loan's monthly payment to find the implied interest rate. This is useful when you have been quoted a monthly payment and want to know the actual APR, or when comparing loan offers where the interest rate is not clearly stated. Enter the loan amount, monthly payment, and term to calculate the annual interest rate. You can also use this tool to find the interest rate needed to grow a savings pot to a target amount over a given period.
