01

Fixed-payment estimate

This calculator assumes a fixed interest rate and equal monthly payments for the life of the loan.

02

Test extra payments

Even a modest additional payment can reduce the principal faster, shortening the payoff period and lowering interest.

03

Check your lender terms

Origination fees, prepayment penalties, variable rates, and payment timing can change the real cost of a loan.
