About this calculator
Fixed-rate loan: the monthly payment is computed with the standard amortization formula and the schedule shows how each payment splits between interest and principal. Extra payments reduce the term and the total interest.
How to use
- 1
Enter the loan amount, annual interest rate and term in years.
- 2
Optionally add an extra monthly payment to see how it shortens the payoff.
- 3
Review the monthly payment, total interest, total paid and payoff time.
Frequently asked questions
How is the monthly payment calculated?
With the standard amortization formula PMT = P·r·(1+r)ⁿ / ((1+r)ⁿ − 1), where P is the principal, r the monthly rate and n the number of payments.
Do extra payments reduce the total interest?
Yes — extra payments reduce the outstanding principal faster, which lowers total interest and shortens the payoff time.
