Frequently Asked Questions

  1. How is monthly payment calculated?

    Monthly payment = P × [r(1+r)^n] / [(1+r)^n - 1], where P = principal, r = monthly interest rate, n = number of payments. We calculate this instantly in your browser.

  2. Is this calculator accurate for real mortgages?

    This tool provides estimates based on the inputs you provide. Actual mortgage payments may include PMI, property tax, insurance, and HOA fees not captured here.

  3. Are my calculations saved?

    No. All calculations happen in your browser. We do not store or log any loan data you enter.
