How to use this house affordability calculator
House affordability is not just the purchase price. A safer estimate looks at monthly income, existing debts, housing costs, down payment, interest rate, and a debt-to-income limit.
Steps
- Enter income, monthly debts, and available down payment.
- Add interest rate, loan term, tax, and insurance assumptions.
- Choose a debt-to-income target.
- Compare the estimate with the mortgage payment calculator.
Calculation method
The calculator estimates a maximum housing payment from income and DTI, subtracts debts and housing expenses, then estimates a price range supported by the remaining payment.
Example scenario
Two buyers with the same income can afford very different homes if one has a large car payment, student loan, or credit card minimums.
Tips for a better estimate
- Keep room for repairs and utilities.
- Use a lower DTI if income is uncertain.
- Run the mortgage calculator for any specific house price.
