Payment math for everything else you finance.

You enter the rate your lender quoted. We give back the payment, the total interest and the full amortization schedule for the loans the big banks bury. No login, no email, no ads on top of your answer.

Today’s benchmark. The U.S. Prime Rate is 6.75% per annum in the Federal Reserve H.15 release as of 2026-09-09, which describes Prime as one of several base rates used by banks to price short-term business loans. Enter the actual rate your lender offered. Prime is context only, not your rate, and is not used in any calculation.
