How This Mortgage Calculator Works
The calculator uses the transparent method shown on this page: Monthly P&I = P × r ÷ [1 − (1 + r)^−n]. The calculation is performed locally in your browser. Inputs are not sent to a remote calculation service simply to produce the answer.
Before relying on any result, confirm that the inputs use the same units, time period and definition. A calculator can make arithmetic repeatable, but it cannot verify whether the source values were entered correctly. For important financial decisions, compare the result with lender, bank, investment-provider or professional documentation that applies to your situation.
A useful check is to change one input by a small amount and confirm that the answer moves in the direction you expect. This sensitivity check can reveal typing errors and also shows which assumptions have the greatest effect on the result.
How to Use It

- Select Calculate.
- Review the main result and supporting details together.
- On smaller screens, the result opens immediately as a compact bottom panel, so you do not need to scroll down to find it.
- Use Copy, Share or Save Result Image when you want to keep the answer.
Worked Example
For a 300,000 mortgage at 6.5% for 30 years, the principal-and-interest payment is calculated from 360 monthly payments. Adding annual property tax and insurance as monthly amounts gives a more useful household cash-flow estimate than showing principal and interest alone.
Common Uses
- Compare different mortgage amounts and terms before requesting quotes.
- Estimate how a rate change affects monthly cash flow.
- Separate loan principal and interest from recurring housing costs.
- Review total interest over the selected repayment period.
How to Interpret the Result
Use the principal-and-interest figure to compare loan structures, then use the total monthly estimate for budgeting. The total monthly amount is not necessarily the lender’s final escrow figure because local tax, insurance, mortgage insurance and lender-specific charges can differ.

Frequently Asked Questions
Does this mortgage calculator include property tax and insurance?
Yes. Enter annual property tax and annual home insurance and the calculator adds one-twelfth of each to the monthly estimate.
Is HOA included in the mortgage payment?
HOA is not part of principal and interest, but you can enter a monthly HOA amount so the total housing-payment estimate includes it.
Is this a lender quote?
No. It is an independent planning estimate based on the values you enter. Actual lender payments and disclosures may include additional items.
