Mortgage Affordability Calculator guide

The mortgage affordability calculator helps you estimate how much home you can afford based on your down payment, interest rate, and monthly budget. We prefill $400,000, 10% down, and a 6.9% rate—adjust these to see how different scenarios change your payment. Lenders typically use a debt-to-income (DTI) ratio; use our DTI calculator to see how your income and debts affect what you qualify for.

Property taxes, insurance, and PMI all affect affordability. The calculator includes them in the total monthly payment so you see the full picture, not just principal and interest. Add extra payments to model accelerated payoff, or switch to biweekly to see interest savings. The amortization table shows how your balance declines over time.

All calculations run client-side. No data is sent to servers. Install the PWA for offline use.

FAQs

Mortgage Affordability Calculator — frequently asked questions

Straight answers about taxes, PMI, extra payments, and biweekly schedules.

How do lenders determine how much I can afford?+

Lenders use debt-to-income (DTI) ratios—typically your total monthly debt payments divided by gross monthly income. Front-end DTI focuses on housing; back-end includes all debts. Use our DTI calculator for details.

Does the calculator include property taxes and insurance?+

Yes. Property tax, homeowners insurance, and PMI (when applicable) are included in the total monthly payment. Adjust the rates to match your area.

How does my down payment affect affordability?+

A larger down payment reduces your loan amount, monthly payment, and PMI duration. It can also help you qualify for better rates. Try different down payment percentages to compare.

What is a good DTI ratio for mortgage approval?+

Many lenders prefer a back-end DTI below 43%, with some flexibility for strong credit. Front-end housing DTI is often capped around 28–31%.

Can I use this with the home affordability calculator?+

Yes. The home affordability calculator focuses on max purchase price. This calculator shows the monthly payment breakdown. Use both together to plan your budget.
