Mortgage Calculator
Calculate monthly mortgage payments, total interest, and the true cost of a home with adjustable down payment, rate, and term.
About Mortgage Calculator
The mortgage calculator estimates your monthly payment from loan amount, interest rate, and term, breaking it into principal and interest.
Knowing your real monthly payment before you commit to a home loan reveals how much house you can actually afford. This tool includes property tax and insurance fields for a complete picture of the true monthly cost.
When to Use Mortgage Calculator
Use it to compare mortgage offers, to size how large a loan your budget supports, or to see the impact of a higher down payment.
Pro Tip
The largest lever on total cost is the interest rate — a 0.5% difference on a 30-year loan is often tens of thousands of dollars.
