Why this page exists

Affordability calculators are most helpful when they connect income, debts, and housing costs in the same place. This version estimates the monthly housing budget first and then works backward into a target home price.

Home affordability calculator

Estimate a target home price from income and debts.

Result

$427,509

Estimated target home price based on income, debt, and housing-cost assumptions.

Estimated home price$427,509

Target monthly housing budget$2,800

Estimated loan amount$367,509

Principal and interest budget$2,275

Your target housing budget is based on keeping total debt near 36.0% of monthly income.
Taxes and insurance absorb about $525 of the monthly housing budget.
Reducing monthly debt or increasing the down payment can move this number significantly.

This is an estimate, not a lending decision or preapproval. Lenders apply their own underwriting rules.

How it works

What the calculator is doing

Enter annual income, monthly debts, and a debt-to-income limit to estimate how much room is available for housing each month.

Use rate, term, tax rate, and insurance inputs to turn that monthly target into an estimated home price and loan amount.

Review the resulting housing budget as a planning number, then compare it against your savings strategy and local market conditions.

Understanding your result

The target home price is only as useful as the assumptions behind it. Debt load, tax rate, insurance, and down payment can move the estimate just as much as interest rate changes do.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Budget around rising rates

Change the mortgage rate to see how quickly buying power moves when financing gets more expensive.

Reduce monthly debt first

Lowering car payments or credit card minimums may increase the housing budget enough to change the range of homes that fit.

Test a larger down payment

A bigger down payment can improve affordability by reducing the loan amount and shrinking the financed portion of the purchase.

FAQ

Common questions

Is this the same as lender preapproval?

No. This tool is an estimate for planning. Lenders apply their own underwriting rules, reserves, credit requirements, and documentation standards.

Why do taxes and insurance matter so much?

They count toward the monthly housing payment, so higher assumptions leave less room for principal and interest.

Can paying off debt improve affordability?

Yes. Lower recurring debt can increase the monthly room available for housing under common debt-to-income guidelines.
