Home Loan Affordability Calculator
Affordability Results
Tip: Include all recurring debts for an accurate estimate. Local taxes and insurance vary by region.
How to Use This Tool
Enter your annual gross income, monthly debts, down payment amount, and other relevant costs. Select your preferred loan term and input the current interest rate. The calculator will estimate your maximum affordable loan amount, home price, and monthly payment. Use the Reset button to clear all fields and start over.
Formula and Logic
The tool uses standard lending guidelines: your total monthly housing payment (including principal, interest, taxes, insurance, and HOA) should not exceed 28% of your gross monthly income. Your total debt-to-income ratio (including all debts) should stay below 43%. The loan amount is calculated using the present value of an annuity formula based on the term, interest rate, and available monthly payment.
Practical Notes
- Local market variation: Property taxes and insurance costs vary significantly by location—always verify with local estimates.
- Closing cost components: Budget 2-5% of the home price for closing costs, including appraisal, title fees, and legal charges.
- Rental yield benchmarks: If considering investment properties, compare the estimated mortgage payment to local rental rates.
- Financing options: Explore FHA, VA, or conventional loans based on your eligibility and down payment capability.
Why This Tool Is Useful
