Mortgage calculator FAQ
How is a mortgage loan payment calculated?
Enter the home price, down payment, interest rate and loan term, and the calculator returns your monthly principal-and-interest payment plus a full amortization schedule. It uses the standard PMT (time-value-of-money) formula lenders rely on, and recalculates instantly as you change any field.
What is included in a monthly mortgage payment?
The core payment is principal and interest. Your true monthly cost — PITI — also adds property taxes and homeowners insurance, plus PMI if your down payment is under 20% and any HOA dues. Use the mortgage calculator with taxes and insurance for the full figure.
Is the mortgage loans calculator free?
Yes. Every calculator on MortgageLoansCalculator is completely free, with no sign-up. The math runs entirely in your browser, so nothing you enter is stored, transmitted or sold.
How much house can I afford?
A common guideline keeps your housing payment under 28% of gross monthly income and total debts under 36%. The home affordability calculator works backward from your income, debts and down payment to a price you can comfortably carry.
How much can I save by making extra payments?
Adding even a small amount to principal each month shortens the loan and cuts total interest, because interest is charged on the remaining balance. Enter an extra monthly payment to see the new payoff date and the interest you would save.
What interest rate should I use?
Start with today’s average and adjust for your credit, down payment and loan type. The mortgage rates page shows current 30- and 15-year averages from official Freddie Mac data, updated weekly.
