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 interest rate, and n is total months.

What is an amortization schedule?

It shows each monthly payment broken down into principal and interest portions, plus the remaining balance after each payment.

Does this include fees or insurance?

No. This calculator only estimates principal and interest. Actual loans may include origination fees, insurance, or other costs.
