Free Mortgage Calculator for Monthly House Payments
ToolsMint Mortgage Calculator estimates your monthly mortgage payment with principal, interest, property taxes, homeowners insurance, HOA fees, and PMI. It is built for home buyers, first-time buyers, refinance research, and anyone comparing loan terms before talking to a lender.
Mortgage Payment Calculator With Taxes, Insurance, and PMI
A basic mortgage calculator can understate the real monthly cost of owning a home. This calculator separates principal and interest from taxes, insurance, HOA, and private mortgage insurance so you can see the full estimated house payment.
Affordability Assistant With DTI Checks
The affordability assistant compares your payment against common front-end and back-end debt-to-income guidelines. It explains when PMI applies, when the payment looks stretched, and how rate changes or a larger down payment can affect the estimate.
Rate Stress Test and Extra Payment Impact
Mortgage rates change quickly. The built-in stress test shows the estimated payment if the rate rises by one percentage point. You can also add an extra monthly payment to estimate how much sooner the loan may be paid off.
Amortization Schedule Download
Review year-end balance snapshots on the page, then download a full monthly amortization CSV with payment, principal, interest, and remaining balance. It is useful for planning, spreadsheets, and comparing loan scenarios.
