Mortgage Calculators
Mortgage calculators for PITI payments, PMI, ARM rates, discount points, biweekly schedules, extra payments, refinance break-even, and amortization.
PITI Calculator (Principal, Interest, Taxes, Insurance)
Calculate full monthly mortgage payment including principal, interest, property tax, homeowners insurance, and PMI. The number lenders use for affordability.
ARM Mortgage Calculator
Compare fixed-rate and adjusted-rate payments for a 5/1, 7/1, or 10/1 ARM. See how rate caps affect your monthly payment after the fixed-rate period ends.
Interest-Only Mortgage Calculator
Calculate interest-only mortgage payments and the higher amortizing payment after the IO period. Compare total interest cost vs a standard amortizing mortgage.
PMI Calculator — Private Mortgage Insurance
Calculate your monthly PMI cost and when it drops off. Enter loan amount, home value, and PMI rate to see your annual and monthly insurance cost.
Extra Mortgage Payment Payoff Calculator
Calculate how many months and how much interest you save by paying extra principal monthly. Enter loan, rate, term, and extra payment for new payoff.
Biweekly vs Monthly Mortgage Payment Calculator
Compare biweekly and monthly mortgage payments. Biweekly pays one extra month per year — calculate years and interest saved over a 30-year loan.
Mortgage Discount Points Buy-Down Calculator
Calculate break-even time and savings from buying mortgage discount points. Each point typically costs 1% of loan and cuts the rate by 0.25%.
