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 รท Gross Monthly Income) ร— 100. Lenders prefer DTI below 36%, with housing costs (front-end ratio) below 28%. For example, if your gross monthly income is โ‚น1,00,000 and your monthly debts (including estimated housing costs) total โ‚น35,000, your DTI is 35%, which is acceptable. However, if your debts total โ‚น40,000, 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 โ‚น1,00,000, monthly debts (car loan, credit cards) are โ‚น15,000, and you have โ‚น10 lakh for a down payment: Maximum monthly housing payment (28% rule) = โ‚น1,00,000 ร— 0.28 = โ‚น28,000. Maximum total monthly payment (36% rule) = โ‚น1,00,000 ร— 0.36 = โ‚น36,000, so maximum housing = โ‚น36,000 - โ‚น15,000 = โ‚น21,000. At 8.5% interest for 20 years, a โ‚น21,000 EMI allows a loan of approximately โ‚น24.5 lakh. With a โ‚น10 lakh down payment, you can afford a home worth approximately โ‚น34.5 lakh. Our calculator factors in all these variables, shows you multiple scenarios, and helps you understand how different factors affect your home affordability.
