Mortgage Calculator

How to use this calculator

Enter the loan amount, interest rate, and term to get your principal-and-interest payment instantly. Add property taxes, insurance, and HOA for a full PITI figure, or an extra monthly payment to see how much faster you’d pay off the loan and how much interest you’d save.

What the metrics mean

• P&I — principal and interest — the core monthly loan payment.
• PITI — P&I plus escrowed taxes, insurance, and HOA: your true monthly cost.
• Total interest — everything you pay the lender beyond the amount borrowed.
• Amortization — how each payment splits between interest and principal as the balance falls.

Frequently asked questions

How is a monthly mortgage payment calculated?

Principal and interest are computed with the standard amortization formula from the loan amount, interest rate, and term. Add property taxes, insurance, and HOA to get your full PITI payment.

What is the difference between P&I and PITI?

P&I is principal and interest — the loan payment itself. PITI adds Taxes and Insurance (and HOA) escrowed each month, so it reflects your true monthly housing cost.

How much do extra payments save?

Paying extra principal each month shortens the loan and cuts total interest. Enter an extra amount and this calculator shows your new payoff time, the interest saved, and the time saved.
