House affordability calculator.

How much home your income supports — with the max price shown at several down payments.

This is a planning estimate, not financial advice or a pre-approval. Actual borrowing limits also depend on your credit, assets and each lender's own rules.

The 28/36 rule

Lenders size a mortgage using two debt-to-income limits: the "front-end" ratio caps housing costs at about 28% of your gross monthly income, and the "back-end" ratio caps all your debt payments (housing plus car, student and credit-card minimums) at around 36%. This calculator applies both and uses whichever is more restrictive, then subtracts your estimated taxes and insurance to find the loan your income supports. Because the down payment simply adds to the price you can pay, the table shows the maximum home price at several down-payment levels. It's a planning estimate — actual approval also weighs your credit score, assets and the lender's own limits. Once you have a target price, the mortgage calculator shows the payment and the cash-to-close estimator the upfront cost.

FAQ

How much house can I afford on my salary?
A common guideline is that total housing costs stay under 28% of gross monthly income and all debt under 36%. Enter your income, debts and down payment above and the calculator works out the maximum loan and home price those limits allow.
Does a bigger down payment let me buy a more expensive house?
Yes — your income sets the loan you can carry, and the down payment adds directly on top. The table shows how the maximum price rises as the down payment increases, with the loan amount staying the same.
