Online Mortgage Calculator

What Is an Online Mortgage Calculator?

An Online Mortgage Calculator is a free financial tool that helps you estimate the monthly principal and interest payment for a potential home loan. By entering the home price, down payment, interest rate, and loan term, you can quickly estimate your monthly mortgage payment and total interest.

Using an Online Mortgage Calculator before shopping for a home can help you compare different mortgage scenarios. You can change the numbers to see how a larger down payment, different interest rate, or shorter loan term may affect your estimated costs.

How Does an Online Mortgage Calculator Work?

The calculator estimates the mortgage loan amount by subtracting the down payment from the home price. It then uses the interest rate and loan term to estimate the monthly principal and interest payment.

The calculator also creates an amortization schedule showing how the balance can decrease over time. This makes it easier to understand how payments may be divided between principal and interest.

How Your Down Payment Affects a Mortgage

The down payment is the amount you pay toward the home at the beginning of the purchase. A larger down payment generally reduces the amount you need to borrow when the purchase price remains unchanged.

For example, if a home costs $400,000 and the down payment is $80,000, the estimated mortgage loan is $320,000 before other costs.

How Interest Rate Affects Your Mortgage Payment

The interest rate represents the annual cost of borrowing money. A higher rate can increase the monthly principal-and-interest payment and can also increase total interest over the life of the loan.

The rate available to an individual borrower depends on many factors. The rate entered into this calculator should therefore be treated as an estimate rather than a guaranteed mortgage offer.

Mortgage Loan Term Explained

The loan term is the number of years used to repay the mortgage. Common mortgage terms include 30 years and 15 years, although other options may be available.

Changing the loan term can change both the estimated monthly payment and total interest. Use the calculator to compare different terms based on your own financial planning assumptions.

Use Your Mortgage Estimate With Your Budget

A mortgage payment is only one part of your overall monthly housing cost. Your budget may also need to account for property taxes, homeowners insurance, mortgage insurance, HOA fees, utilities, maintenance, and other expenses.

After estimating your mortgage payment, use our Budget Calculator to organize your monthly income and expenses.

You can also use our Free Expense Tracking tool to monitor spending and our Savings Goal Calculator to plan future savings.
