Mortgage Payment Guide: Estimate Monthly House Payments

A mortgage calculator estimates how much you may pay each month based on home price, down payment, interest rate, and loan term.

The Main Inputs

• Home price: The purchase price of the property.
• Down payment: Money paid upfront, which reduces the loan amount.
• Interest rate: The yearly rate charged by the lender.
• Loan term: Common terms are 15, 20, or 30 years.

Principal and Interest

The monthly mortgage payment is mainly made of principal and interest. Principal reduces your loan balance. Interest is the cost of borrowing money. Early in a mortgage, more of the payment usually goes toward interest. Later, more goes toward principal.

Example

If a home costs $400,000 and the down payment is $80,000, the loan amount is $320,000. The monthly payment then depends on the interest rate and term. A higher rate or shorter term usually increases the monthly payment, but a shorter term can reduce total interest paid over the life of the loan.

What a Basic Mortgage Calculator May Not Include

Property taxes, homeowners insurance, HOA fees, closing costs, private mortgage insurance, and local fees can change the real monthly housing cost. Use the calculator for a principal-and-interest estimate, then add those costs for a fuller budget.

FAQ

Does a bigger down payment lower monthly payments?

Yes. A larger down payment reduces the loan amount, which usually lowers the monthly payment.

Does a 15-year mortgage cost less overall?

Often yes, because interest is paid over fewer years, but monthly payments are usually higher.
