What is Mortgage Payment Calculator?

A home mortgage payment consists of principal repayment, interest charges, local property taxes, and homeowners insurance (often abbreviated as PITI). Our Mortgage Calculator estimates total monthly home loan costs based on purchase price, down payment (amount or percentage), loan term, interest rate, and escrow expenses directly in your browser.

Designed for accuracy, speed, and privacy, this tool runs entirely on your local device with zero network latency.

Formula & Calculation Logic

Computes fixed-rate mortgage principal and interest amortization combined with linear monthly escrow allocations for property tax and hazard insurance.

Monthly P&I: M = P * [r(1 + r)^n] / [(1 + r)^n - 1] + (Annual Taxes / 12) + (Annual Insurance / 12)
