payment = P × r ÷ (1 − (1 + r)^−n), where r is the monthly rate (annual rate ÷ 12) and n is the number of payments.

what do extra payments do?

extra money each month goes straight to principal, which shortens the loan and cuts total interest. the table shows the shorter payoff.

are the results exact?
