Calculate your mortgage payment, total housing costs, and amortization schedule. See monthly payments, interest paid, equity built, and the true cost of homeownership over time—including property tax, insurance, HOA, and maintenance.
Our mortgage calculator estimates your monthly payment, total housing costs, and amortization schedule. It models property appreciation, tax, insurance, HOA, maintenance, PMI, rate buydowns, and other real costs of homeownership.
We use real amortization schedules to track how your mortgage balance declines. Early payments are mostly interest; over time, more goes toward principal. Accumulated equity offsets your total cost of ownership.
Monthly principal and interest use the standard amortization formula:
PMT = P × [r(1+r)n] / [(1+r)n − 1]
Where P = loan principal, r = monthly interest rate (annual ÷ 12), n = total number of payments.
The calculator includes mortgage P&I, property tax, home insurance, HOA, PMI, maintenance, closing costs, permanent and temporary rate buydowns, and optional tax deduction. Tax benefit is modeled as itemized mortgage interest (first $750k debt) + property tax (up to $10k SALT cap), above the 2026 standard deduction for your selected filing status.
