House Affordability Calculator: Determine How Much Home You Can Afford
A house affordability calculator helps you determine the maximum home price you can afford based on your income, monthly debts, down payment, interest rate, and loan term. Lenders typically use the 28/36 rule: your monthly housing costs (PITI: Principal, Interest, Taxes, Insurance) should not exceed 28% of your gross monthly income, and your total monthly debts (including housing) should not exceed 36% of your gross monthly income. However, these ratios can vary based on credit score, location, and lender requirements. Understanding your affordability helps you set realistic home-buying goals and avoid overextending your finances.
Debt-to-Income (DTI) Ratio: Your DTI ratio is calculated as (Total Monthly Debts ÷ Gross Monthly Income) × 100. Lenders prefer DTI below 36%, with housing costs (front-end ratio) below 28%. For example, if your gross monthly income is ₹1,00,000 and your monthly debts (including estimated housing costs) total ₹35,000, your DTI is 35%, which is acceptable. However, if your debts total ₹40,000, your DTI is 40%, which may disqualify you or require a larger down payment. Factors affecting affordability include: income stability, credit score, existing debts, down payment amount, interest rates, property taxes, insurance costs, and HOA fees (if applicable).
Example: If your gross monthly income is ₹1,00,000, monthly debts (car loan, credit cards) are ₹15,000, and you have ₹10 lakh for a down payment: Maximum monthly housing payment (28% rule) = ₹1,00,000 × 0.28 = ₹28,000. Maximum total monthly payment (36% rule) = ₹1,00,000 × 0.36 = ₹36,000, so maximum housing = ₹36,000 - ₹15,000 = ₹21,000. At 8.5% interest for 20 years, a ₹21,000 EMI allows a loan of approximately ₹24.5 lakh. With a ₹10 lakh down payment, you can afford a home worth approximately ₹34.5 lakh. Our calculator factors in all these variables, shows you multiple scenarios, and helps you understand how different factors affect your home affordability.
