Frequently Asked Questions

What formula does this use?

This calculator uses the standard fixed-rate 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.

Does this include taxes, insurance, or fees?

No — this calculates principal and interest only. Real-world loans (especially mortgages) often include additional costs like taxes, insurance, or origination fees.
