Calculate monthly mortgage payments including principal, interest, property tax, and insurance (PITI). View full amortization schedule and total interest paid over loan life.
Follow these simple steps to get instant, accurate results directly in your browser:
Input the total home price and your down payment amount or percentage.
Specify the loan duration (e.g. 30 years, 15 years) and the annual fixed interest rate.
Review your estimated monthly payment, total interest paid over life of loan, and amortization chart.
The Mortgage Calculator computes monthly mortgage payments, loan amortization schedules, total interest costs, and payoff timelines for home purchases, refinancing, and real estate investments.
The calculator uses standard fixed-rate monthly compounding amortization formulas. It computes principal and interest (P&I) alongside property taxes, home insurance, and private mortgage insurance (PMI). Users can inspect detailed month-by-month and year-by-year amortization schedules showing how the loan balance shifts from interest-heavy to principal reduction over time.
All mortgage modeling runs client-side in your browser. Your confidential home purchase budgets, income projections, and down payment figures are never transmitted to any bank or server.

M = P * [r(1 + r)^n] / [(1 + r)^n - 1]Where M is the monthly payment, P is the principal loan balance, r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments (years multiplied by 12).
Home Loan Principal P = $300,000 Annual Rate = 6.0% -> Monthly rate r = 0.06 / 12 = 0.005 Term = 30 Years -> n = 360 payments M = 300,000 * [0.005(1 + 0.005)^360] / [(1 + 0.005)^360 - 1] M = 300,000 * [0.005 * 6.022575] / [5.022575] = $1,798.65 per month Total payments over 30 years: $647,514.57 (Total Interest: $347,514.57).
