About This Calculator

This calculator breaks down your monthly principal and interest payment based on the loan amount, rate, and term. It doesn't include taxes, insurance, or HOA fees — but the P&I figure is the foundation of every mortgage comparison and affordability analysis.

Estimates only — not financial, tax, legal, or investment advice. Verify important results with a qualified professional before making decisions.

PMT = P × r / (1 − (1+r)^−N); total paid = PMT × N; total interest = total paid − P — where r = annual rate ÷ payments/year, N = years × payments/year
