Frequently asked questions

How is the monthly payment calculated?

We use the standard amortization formula M = P × r(1+r)^n / ((1+r)^n - 1), where P is principal, r is the monthly interest rate, and n is the number of payments.

What if my loan has 0% interest?

For zero-interest loans, the calculator simply divides the principal evenly across the number of payments.

What does the amortization table show?

It shows a year-by-year breakdown of how much principal and interest you pay, and your remaining loan balance at the end of each year.
