Frequently Asked Questions

How is the monthly payment calculated?
Using the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is principal, r is monthly rate, and n is number of payments.
Does it account for variable rates?
This calculator assumes a fixed interest rate. For variable rate loans, the payment may change over time as the rate adjusts.
