Principal
Principal is the amount borrowed for the home. Each principal payment reduces the outstanding loan balance.
Estimate your monthly mortgage payment, compare different loan scenarios, and understand how your home price, down payment, interest rate and loan term can affect your housing budget.
Enter your actual loan assumptions to estimate your monthly principal and interest payment. You can also include property taxes, homeowners insurance, PMI and HOA fees for a broader housing-cost estimate.
Optional costs are not required to calculate principal and interest. Add them when you have reliable estimates for the property.
Enter the required loan details to calculate your estimated monthly payment and total interest.
Results are estimates for educational and planning purposes. Actual mortgage payments, rates, taxes, insurance and other costs may differ.
A home loan calculator gives you a practical way to estimate borrowing costs before you begin comparing actual mortgage offers. At its core, a mortgage payment calculation uses the amount borrowed, interest rate and repayment period to estimate the principal-and-interest payment.
Your starting loan amount is influenced by the home's purchase price and the amount you pay upfront. A larger down payment generally means a smaller amount needs to be financed.
Your monthly housing cost can extend beyond principal and interest. Property taxes, homeowners insurance, mortgage insurance and HOA fees may all affect the amount you need to budget each month.
Using a calculator to test different scenarios can help you understand these relationships before you move forward with a lender or make an offer on a property.
Your principal-and-interest payment is important, but your overall housing budget can include several other recurring costs.
Principal is the amount borrowed for the home. Each principal payment reduces the outstanding loan balance.
Interest is the cost of borrowing. The rate and outstanding loan balance affect how much interest accrues.
Property taxes are determined locally and can vary significantly depending on the property's location.
Homeowners insurance premiums depend on the property, location, coverage and insurer.
Your down payment is the portion of the home's purchase price that you pay upfront. The remaining amount is generally financed through a mortgage.
A larger down payment means you borrow less. A smaller loan balance can reduce the scheduled principal-and-interest payment and may also reduce total interest over the life of the mortgage.
Your down payment can also affect mortgage insurance requirements. The rules depend on the mortgage program, lender and borrower circumstances.
It is also important to consider how much cash you want to keep available for closing costs, emergency savings, moving expenses, maintenance and other financial needs.
Your interest rate affects the cost of borrowing and the amount of interest that can accumulate throughout the mortgage term.
The loan term determines how long you have to repay the balance. A longer term can reduce the scheduled monthly principal-and-interest payment, while a shorter term can increase the monthly payment but reduce the repayment period.
Comparing different combinations of rates and terms can help you understand the trade-off between monthly affordability and total borrowing cost.
A fixed-rate mortgage uses an amortization schedule to divide each scheduled principal-and-interest payment between interest and principal.
Early in the mortgage, the outstanding balance is relatively high, so a larger portion of the scheduled payment generally goes toward interest. As the balance declines, the interest portion can fall while the principal portion increases.
The scheduled principal-and-interest payment on a typical fixed-rate mortgage can remain level even though the internal split changes from payment to payment.
The loan balance is highest near the beginning of the repayment period.
As the balance falls, less interest accrues against the remaining balance.
A basic mortgage calculation may show only principal and interest. Your actual monthly housing budget can be broader.
Depending on the property and mortgage, you may also need to account for property taxes, homeowners insurance, mortgage insurance and HOA or condominium fees.
These costs can vary considerably between properties, even when two homes have similar purchase prices.
When you have actual figures from your lender, insurer, local tax authority or homeowners association, use those numbers instead of broad estimates.
Start by entering the purchase price of the home you are considering and the amount you expect to put down. The calculator uses these figures to determine the amount that would need to be financed.
Next, enter an interest rate and loan term that match the mortgage scenario you are researching. If you are comparing several mortgage options, test different rates and terms rather than relying on one estimate.
The optional fields let you include property taxes, homeowners insurance, PMI and HOA fees. Adding reliable estimates can make your monthly housing budget more useful for planning.
The calculator is especially useful for comparing scenarios. You can see how changing the down payment, interest rate or repayment term affects your estimated monthly payment and total interest.

Understand your numbers before comparing home loan options.
A mortgage calculator can estimate the principal-and-interest payment using the loan amount, interest rate and repayment term. Additional fields can be used to estimate broader monthly housing costs.
For a typical fixed-rate mortgage, the principal-and-interest payment is calculated from the loan balance, interest rate and repayment term. Taxes, insurance and other costs can then be added separately.
Generally, a larger down payment means a smaller amount needs to be financed. A smaller loan balance can reduce the scheduled principal-and-interest payment and may also reduce total interest.
Yes. You can enter an estimated annual property tax amount. The calculator converts that annual figure into an estimated monthly cost.
PMI stands for private mortgage insurance. It may apply to certain conventional mortgages depending on the down payment, lender and loan circumstances.
A longer repayment term generally lowers the scheduled monthly principal-and-interest payment, but it can increase the total interest paid over the life of the mortgage.
No. Calculator results are estimates. Actual mortgage terms depend on the borrower, property, loan program, lender, interest rate and other factors.
It can be useful for planning. Comparing different purchase prices, down payments, interest rates and loan terms can help you prepare for actual mortgage discussions.
Test different home prices, down payments, interest rates and loan terms to build a clearer picture of your potential housing cost.
