How does the home affordability calculator work?

It uses your income and debts to estimate a comfortable home price range, typically by applying a debt-to-income ratio and down payment assumptions.

What inputs do I need to use this calculator?

You'll need your gross annual income, monthly debt payments, down payment amount, and possibly interest rate and loan term to get an estimate.

Is the result a guaranteed loan approval amount?

No, it's an estimate. Lenders consider additional factors like credit score, assets, and exact debt ratios, so final approval may differ.

Tips & Common Mistakes

Tips

Enter your gross annual income (before taxes) for accuracy.
Include all monthly debt payments like car loans, student loans, and credit card minimums.
Consider a down payment of at least 20% to avoid private mortgage insurance (PMI).
Use the result as a starting point, then get pre-approved by a lender.

Common Mistakes to Avoid

Forgetting to include all monthly debts, which can overestimate affordability.
Using net income instead of gross income, leading to a lower estimate.
Ignoring additional homeownership costs like property taxes, insurance, and maintenance.
