Find the effective interest rate of multiple mortgages, loans or lines of credit at the same time.
This more detailed calculator derives the blended rate of up to four loans or lines of credit at any given month and then averages those blended rates over the total length of all loans to calculate an average blended rate. Buttons are included to calculate 5, 10, 15, 20, 25 and 30 year loan or interest only payments based on a given balance and rate. Otherwise you must enter your own known monthly payment.
