What Is a Mortgage Affordability Calculator?

This tool estimates a home-price range from income, recurring debt, down payment, assumed interest rate, taxes, insurance, and a target housing ratio. It is a planning estimate, not a lender pre-approval.

Who Should Use This Tool?

Prospective buyers can use it before speaking with a lender to understand how payment assumptions and existing debts affect a potential budget.

Examples

Income and Debt Check

Example Input

$120,000 gross household income, $800 monthly debt, 20% down payment, 6.5% assumed rate.

Sample Output

Estimates a target home-price range using the entered income, debt, rate, taxes, insurance, and affordability assumptions.

Conservative Budget

Example Input

$90,000 income, $500 monthly debt, 10% down payment, and a lower target housing ratio.

Sample Output

Shows how a more conservative housing budget changes the estimated price range and required cash.

Common Use Cases

Test a larger down payment, a different rate, or a more conservative housing ratio. Compare the output with our mortgage calculator and debt-to-income calculator.

How to Get a Better Estimate

Use gross monthly income and minimum recurring debt payments, then add realistic property tax, insurance, HOA, and mortgage-insurance assumptions. Ask lenders which ratios and documentation they use.

Common Mistakes

Do not treat the highest modeled price as a recommendation. It may exclude maintenance, utilities, childcare, variable income, reserves, and lender-specific underwriting rules.

FAQ

How much house can I afford?

It depends on income, debts, down payment, rate, taxes, insurance, reserves, and lender rules. Use the result as a range to discuss with a lender, not as an official loan approval amount.

What is the 28/36 rule?

The 28/36 rule is a common budgeting guideline involving housing and total debt ratios, but lenders and loan programs use their own criteria and may apply different limits.

Does this replace mortgage pre-approval?

No. A lender must verify income, assets, debts, credit history, property details, and program requirements before issuing approval terms.

Why is the affordable home price lower than I expected?

Affordability is constrained by income, existing debt, interest rate, down payment, property taxes, insurance, HOA costs, and the debt-to-income limit. Test the result with the actual monthly housing costs and avoid treating a lender maximum as a comfortable budget.

Why Use This Calculator?

The calculator keeps your assumptions visible and runs in your browser, helping you compare a few planning scenarios before sharing documents with a lender.
