Mortgage Payment Calculator computes the monthly P&I payment for any loan amount using a standard PMT formula, compares 30- and 15-year terms, and shows how your rate and down payment affect the payment.
Mortgage Payment Calculator is a high-performance utility designed to help users streamline their workflow. Built with modern web technologies, it ensures fast processing times and high-quality outputs directly in your browser.
Monthly P&I uses the standard PMT annuity formula: loan × r × (1+r)^n / ((1+r)^n − 1), where r = monthly rate and n = term in months. Loan = purchase price × (1 − down%). Property tax and insurance are not included. Rate assumptions are illustrative; actual rates vary by credit score and lender.
PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a full monthly mortgage payment. Lenders use your total PITI to calculate your debt-to-income ratio.
Using the 28% rule, your monthly PITI should not exceed 28% of your gross monthly income. For a $5,000/month income, that's $1,400/month max for housing costs.
As of 2026, average 30-year fixed rates are around 6.5–7.5%. A rate below the current average is generally considered good. Rates vary by credit score, down payment, and lender.
A 15-year mortgage has ~40% higher monthly payments than a 30-year but saves roughly half the total interest. A 30-year offers lower payments and more cash flow flexibility.
