About US Mortgage Calculator

Free, accurate mortgage calculations to help you understand the true cost of homeownership.

What We Do

Our mission is to provide accurate, easy-to-use tools that help you understand the true cost of homeownership — not just the principal and interest, but all associated costs including property taxes, homeowners insurance, PMI, and HOA fees.

How Our Calculations Work

We use the standard amortization formula: M = P x [r(1+r)^n] / [(1+r)^n - 1], where P is the loan amount, r is the monthly interest rate, and n is the total number of payments. This is the same formula used by banks and lenders.
