Home Loan Affordability Calculator — Find the Maximum Home Loan You Can Realistically Afford

Before visiting a bank or shortlisting a property, the most important question is: how much home loan can you actually afford — not just qualify for? There's a meaningful difference. Banks may approve a loan up to 6–7 times your annual income, but whether you can comfortably service that EMI while covering living expenses, emergencies, investments, and future goals is a separate question entirely. This Home Loan Affordability Calculator answers that question honestly. Enter your monthly income, monthly expenses, expected interest rate, loan tenure, and down payment — and instantly see the maximum loan amount you can take without stretching your finances dangerously thin.

The result is an affordability-based estimate — grounded in the 40–50% FOIR (Fixed Obligation to Income Ratio) standard that Indian banks use — not just a maximum eligibility number. It tells you what you can manage, not just what a lender will sanction.

The Affordability Formula — How It Works

The calculator first determines your maximum affordable EMI based on your net income (income minus expenses), applying the 40–50% FOIR standard. It then reverse-calculates the loan principal using the standard EMI formula: 

Loan Amount = [EMI × ((1 + r)^n − 1)] ÷ [r × (1 + r)^n]

Where: EMI = maximum affordable monthly payment (net income × 50%), r = monthly interest rate (annual rate ÷ 12 ÷ 100), n = total months (tenure × 12).

Example 1 — Ramesh: Monthly income ₹60,000, expenses ₹20,000 → net income ₹40,000. Max EMI (50%) = ₹20,000. At 8% for 20 years: r = 0.00667, n = 240. Maximum Affordable Loan ≈ ₹23,96,000. Add down payment ₹4,00,000 → Total home budget ≈ ₹27,96,000.

Example 2 — Priya: Monthly income ₹85,000, expenses ₹25,000 → net income ₹60,000. Max EMI (50%) = ₹30,000. At 8.5% for 20 years: r = 0.00708, n = 240. Maximum Affordable Loan ≈ ₹34,75,000. Add down payment ₹10,00,000 → Total home budget ≈ ₹44,75,000.

FOIR — The Single Most Important Number in Loan Eligibility

FOIR (Fixed Obligation to Income Ratio) is the percentage of your net monthly income committed to all fixed EMI obligations — existing loan EMIs plus the proposed home loan EMI. Most Indian banks cap FOIR at 40–50% for salaried applicants (lower for self-employed). Understanding FOIR explains why:

  • A person with ₹1 lakh salary and ₹40,000 existing EMIs will get a much smaller home loan than someone with ₹1 lakh salary and zero existing loans
  • Closing a car loan or personal loan before applying for a home loan directly increases your maximum affordable home loan amount
  • Adding a co-applicant (spouse, parent) increases total qualifying income, raising the FOIR ceiling and therefore the loan amount

Practical tip: If you have existing EMIs, subtract them from your ₹40–50% FOIR allocation when using this calculator. Enter only the remaining available budget as your effective affordability ceiling.

LTV Ratio — How Much Will the Bank Actually Lend?

Banks don't lend 100% of the property value — RBI guidelines cap home loan LTV (Loan-to-Value) ratios as follows:

  • Property value up to ₹30 lakh: Maximum LTV = 90% (minimum 10% down payment)
  • Property value ₹30 lakh to ₹75 lakh: Maximum LTV = 80% (minimum 20% down payment)
  • Property value above ₹75 lakh: Maximum LTV = 75% (minimum 25% down payment)

This means a ₹80 lakh property requires at least ₹20 lakh down payment — the bank lends a maximum of ₹60 lakh regardless of your affordability calculation. Always validate your affordability estimate against the required minimum down payment for your target property bracket.

Hidden Costs That Affect True Affordability

The loan amount is only one part of the home-buying cost. Factor in these additional expenses when planning your budget:

  • Stamp duty and registration: 3–7% of property value depending on state and gender of buyer (Maharashtra: 5–6%; Karnataka: 5.6%; Delhi: 4–6%)
  • GST on under-construction property: 5% on property value (affordable housing at 1%); nil for ready-to-move properties with OC
  • Processing fee: 0.25–1% of loan amount charged by lenders at disbursement
  • Interior/renovation: ₹5–25 lakh for a new home depending on size and finish level
  • Maintenance deposit and society charges: Common in new housing societies — can be ₹50,000–₹5,00,000

A realistic budget should account for: down payment + stamp duty + registration + GST (if applicable) + processing fees + emergency renovation buffer. For a ₹60 lakh property, total initial outgo before you move in could reach ₹20–25 lakh including loan costs.

Frequently Asked Questions About Home Loan Affordability

A bank's eligibility calculator tells you the maximum they will sanction based on their credit policies, CIBIL score, and income verification. This affordability calculator tells you the maximum you should borrow to remain financially comfortable — based on your net income after expenses and the standard 40–50% FOIR guideline. Banks can sometimes approve more than you can comfortably repay; this calculator provides a more conservative, practical ceiling. Use it as your personal benchmark before engaging with lenders.
Yes — adding a co-applicant (spouse, parent, or adult child) increases combined qualifying income, directly raising the affordable EMI ceiling and therefore the loan amount. Banks require the co-applicant to be a co-owner of the property. Additional benefit: both co-applicants can independently claim income tax deductions on the home loan — ₹1.5 lakh each under 80C (principal) and ₹2 lakh each under Section 24(b) (interest) under the old regime, effectively doubling the tax benefit. For this calculator, add both incomes and both expense totals to get the joint affordability figure.
Use 40% FOIR as your personal safety threshold and 50% as the absolute maximum. At 50% FOIR, half your take-home is committed to EMIs — any income disruption (job loss, medical emergency) immediately threatens repayment. At 40%, you have a meaningful cushion. As a rule: if you have young children with high education costs ahead, existing car/personal loans, or a variable-income job, target 35–40% FOIR. If you have stable dual income, no other loans, and strong emergency savings, 45–50% FOIR is manageable.
Financially yes — a larger down payment reduces the loan principal, saving total interest paid and reducing monthly EMI. However, it only makes sense if: (1) you won't drain your emergency fund (keep 6 months of expenses liquid), and (2) the funds aren't better deployed in higher-return investments. If your home loan rate is 8.5% and you can earn 10–12% in equity mutual funds, mathematically investing is better. But home loan repayment provides a guaranteed, risk-free "return" equal to the interest rate. The right balance depends on your risk profile and financial security.
Under-construction: typically lower price, but you pay GST (5%), pre-EMI interest during construction phase (2–3 years), and bear delivery and quality risk (RERA has improved but not eliminated this). Ready-to-move: no GST, immediate possession, no pre-EMI period — but higher sticker price and limited new inventory in prime areas. From an affordability perspective, under-construction properties have a lower base price but higher total outgo when GST and carrying costs are factored in. For first-time buyers with tight budgets, ready-to-move often provides better financial predictability.
Banks cap the loan tenure such that the last EMI falls before (or at) the borrower's retirement age — typically 60 for salaried and 65 for self-employed. A 25-year-old applying for a home loan can get up to a 35-year tenure; a 45-year-old is typically restricted to 15–20 years. Shorter available tenure means higher mandatory EMI for the same loan amount — reducing affordability for older applicants. Adding a younger co-applicant (child or spouse) can help extend the tenure and improve affordability in such cases.
PMAY (Pradhan Mantri Awas Yojana) is a government subsidy scheme for affordable housing. Under the Credit Linked Subsidy Scheme (CLSS), eligible first-time homebuyers receive an upfront interest subsidy credited directly to the loan account — effectively reducing the principal. Under PMAY 2.0 (announced in the 2024 Union Budget), new categories and subsidy amounts apply. The subsidy can reduce effective loan cost by ₹2–6 lakh depending on income category, meaningfully improving affordability for EWS, LIG, and MIG households. Check PMAY eligibility at the official PMAY portal before finalising your home purchase.
