What is Mortgage Calculator?

A mortgage calculator estimates your monthly home loan payment from the loan amount, interest rate, and term.

Definition: Mortgage Calculator estimates the principal-and-interest payment for a fixed-rate home loan.

Formula

PMT = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1] where r = APR/12, n = months

Calculation steps

  1. The core formula: PMT = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1] where r = APR/12, n = months
  2. Enter your values in the fields above — units and assumptions are under your control.
  3. The Daily Tools computes the result instantly in your browser using JavaScript.
  4. Review the result panel for the primary output and supporting breakdown values.

Worked example

Example: $320,000 mortgage at 6.5% for 30 years

Inputs: Principal = $320,000, APR = 6.5%, Term = 30 years

  1. Monthly rate = 6.5% ÷ 12 = 0.5417%
  2. Number of payments = 30 × 12 = 360
  3. Apply standard amortization (PMT) formula

Estimated monthly payment ≈ $2,022 (excluding taxes and insurance).
