What this mortgage estimator covers
This calculator uses a standard fixed-rate amortization formula for principal and interest. It can also layer in annual property tax, annual insurance, and monthly HOA dues so you can see a more realistic monthly housing payment instead of principal and interest alone.
What the result does not replace
It does not replace a lender's Loan Estimate, underwriting review, closing disclosure, PMI calculation, escrow setup, or rate lock. Treat it as a planning tool for scenario comparison, not as a final borrowing quote.
Practical ways to use it
Compare 15-year vs 30-year terms, test a different down payment, or see how taxes and insurance change the payment. That helps you separate the house price from the total monthly obligation before you commit to a range.
Assumptions behind the number
The estimate assumes a fixed rate for the full term. If you are evaluating an adjustable-rate mortgage, lender credits, points, PMI, or unusually high closing costs, those need to be reviewed separately.
Key features
- Complete monthly picture: See principal + interest (P&I) plus estimates for taxes and insurance to gauge the true monthly cost.
- Long-term impact: View total interest over 15 or 30 years to understand how rates and down payments affect the lifetime cost.
- Fast scenario testing: Tweak down payment, term, or tax estimates to compare multiple homes or offers instantly.
Frequently asked questions
Does it include PMI or HOA fees?
PMI and HOA fees are not included by default. Add them to the insurance field or note them separately.
What is PITI?
PITI stands for Principal, Interest, Taxes, and Insurance. It represents your total monthly housing cost, not just the loan repayment.
Why is the payment higher than the car loan calculator?
Mortgages often include property taxes and homeowner’s insurance, which are added on top of principal and interest.
How does amortization work?
In the early years, most of your payment goes toward interest. Over time, more goes toward the principal. Check the "Total Interest" stat to see the long-term cost.
Can I save my inputs?
Values stay in the fields during your current session. Refreshing the page resets the calculator.
