Calculate your estimated monthly principal and interest payment.
This Mortgage Calculator is designed for home buyers, homeowners, real estate shoppers, first-time buyers, mortgage comparison researchers, and anyone planning a housing budget. A mortgage payment calculator helps estimate the monthly principal and interest portion of a home loan by using the home price, down payment, annual interest rate, and loan term. Instead of guessing whether a home is affordable, you can quickly test different purchase prices, down payment amounts, interest rates, and repayment periods.
Mortgage planning is important because a home loan is often the largest long-term financial obligation a household will take on. Even a small change in mortgage rate, loan amount, or amortization length can change the monthly payment and total interest cost significantly. This home loan calculator provides a clear estimate of your monthly mortgage payment, total interest paid, loan amount, down payment percentage, and total estimated payment over the life of the mortgage.
A standard fixed-rate mortgage payment is based on the loan principal, monthly interest rate, and total number of payments. The principal is the amount borrowed after subtracting your down payment from the home price. The interest is the cost charged by the lender for borrowing money. This calculator uses a common amortized loan formula to estimate the monthly principal and interest payment.
A larger down payment reduces the mortgage loan amount and can lower the monthly payment. It may also reduce total interest paid over the life of the loan. In some markets, a lower down payment may require mortgage insurance, which can increase the real monthly housing cost. Comparing several down payment amounts can help you find a more realistic home buying budget.
A 30-year mortgage usually offers a lower monthly payment because the loan is spread over a longer period. However, the total interest cost is often higher. A 15-year mortgage usually has a higher monthly payment, but it can reduce total interest and build home equity faster. This mortgage calculator lets you compare shorter and longer loan terms quickly.
Mortgage interest rates have a major effect on affordability. A small difference in rate can change the monthly payment and lifetime interest cost by thousands of dollars. Buyers often use a mortgage interest calculator to compare different lender quotes, fixed-rate options, and possible future refinancing scenarios before committing to a loan.
Start by entering the expected home price. Then enter your planned down payment, annual mortgage interest rate, and preferred loan term. The calculator will estimate your monthly mortgage payment for principal and interest only. It will also show the estimated loan amount, down payment percentage, interest rate, total interest paid, and total estimated payment over the selected loan term.
You can use this tool repeatedly to compare different buying scenarios. For example, you can test how a larger down payment changes your monthly payment, how a 15-year loan compares with a 30-year loan, or how a higher mortgage rate changes total interest. This makes the tool useful for home affordability planning, mortgage pre-approval preparation, refinancing research, and real estate decision making.

This calculator focuses on principal and interest. A real monthly housing payment may include property taxes, homeowners insurance, mortgage insurance, HOA fees, utilities, maintenance, repairs, closing costs, and local assessments. When building a complete housing budget, these additional costs should be considered separately from the basic mortgage payment estimate.
Buyers should also consider emergency savings, moving expenses, furniture, renovation costs, inspection fees, appraisal fees, legal fees, title costs, and ongoing maintenance. A mortgage payment that looks affordable on paper may become difficult if the full cost of homeownership is not included in the budget.
When comparing mortgage offers, review more than the monthly payment. Compare the interest rate, APR, lender fees, points, closing costs, prepayment rules, fixed versus variable terms, renewal conditions, and total interest. A lower monthly payment may not always mean a cheaper mortgage if the loan term is longer or fees are higher. Use this mortgage payment estimator as a starting point, then confirm exact numbers with a qualified mortgage professional.
This calculator estimates principal and interest based on home price, down payment, interest rate, and loan term. It does not include taxes, insurance, HOA fees, or mortgage insurance.
A 15-year mortgage usually has higher monthly payments but may reduce total interest. A 30-year mortgage usually has lower monthly payments but may cost more in interest over time.
A larger down payment reduces the loan amount, which can lower monthly payments and total interest. It may also reduce or eliminate mortgage insurance depending on lender rules and local requirements.
The interest rate determines the cost of borrowing. Even a small rate difference can significantly change the monthly payment and total interest paid over a long mortgage term.
Yes. You can enter your expected refinance loan amount as the home price and use zero as the down payment, or adjust the inputs to match your refinancing scenario.
