Enter your total monthly income from all sources after tax - salary, rent, freelance, interest, and any other regular inflows. This is the base on which your affordable EMI is calculated.
Rs
Your rent, food, utilities, transport, insurance, and other month-to-month costs. Subtract these from your income to get the surplus you can responsibly pledge to a home loan EMI.

Most affordability calculators ignore your current loans - a bank never does. Add the EMIs of any car, personal, or education loans you already pay. These consume a share of your FOIR, so they directly reduce the home loan you can take.
%
Most banks cap FOIR at 40-50% of net income. This is the percentage of your income-after-expenses that goes to all EMIs together. Unlike other calculators, you can set your own target - use 40% for a comfort buffer or 50% as the absolute ceiling.

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 is 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, existing loan EMIs, 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. A bank might happily sanction a Rs 60 lakh loan on an Rs 80,000 monthly salary - but that does not mean paying Rs 52,000 in EMI while managing rent, food, and commute on Rs 28,000 is wise.

The New Features - What You Get Here That Other Home Loan Affordability Calculators Don't

Most affordability calculators take your income, a fixed ratio, rate, and tenure, and return a single loan number. This calculator layers on five extras that turn that simple answer into a realistic borrowing plan:

1. Adjustable FOIR. Most tools hardcode a 50% ratio you cannot change. This calculator lets you slide your FOIR from 25% to 60%, with presets for 35%, 40%, 45%, and 50%. Target 40% for a safety buffer or 50% as the absolute ceiling - you decide how aggressive to be, and the loan amount changes instantly.

2. Existing EMI Input. If you already pay a car, personal, or education loan, a bank deducts it from your FOIR - but most affordability calculators ignore it entirely and overstate what you can borrow. Add your existing EMIs here and the calculator subtracts them from your available budget, mirroring how a lender really evaluates you.

3. RBI Loan-to-Value (LTV) Down Payment Check. The maximum loan you can take is not only limited by income - it is also limited by the property price and the minimum down payment the RBI rules require. This calculator checks your down payment against the 90%, 80%, or 75% LTV bracket for your property price and shows the exact shortfall if you do not have enough cash saved.

4. EMI and Total Interest Preview. Beyond the loan amount, it shows the monthly EMI on your maximum loan and the total interest you will pay over the full tenure - so you never sign up for a loan without knowing the true lifetime cost.

5. Net-Income Donut, Insights, and Tenure Comparison. A donut shows how much of your net income goes to the home loan EMI, insights translate the numbers into decisions, and a breakdown compares EMI and total interest at different tenures.

The Affordability Formula - How It Works

The calculator first works out your net monthly surplus (income minus expenses), then sets your maximum affordable EMI as that surplus multiplied by your FOIR, less any existing EMIs. It then reverse-calculates the loan principal using the standard EMI formula: 

Loan Amount = [EMI x ((1 + r)^n - 1)] / [r x (1 + r)^n]

Where: EMI = your affordable monthly payment (surplus x FOIR - existing EMIs), r = monthly interest rate (annual rate / 12 / 100), n = total months (tenure x 12).

Example 1 - Ramesh: Monthly income Rs 60,000, expenses Rs 20,000, no existing EMIs, FOIR 50% - net income Rs 40,000, max EMI Rs 20,000. At 8% for 20 years: r = 0.00667, n = 240. Maximum Affordable Loan about Rs 23,96,000. Add Rs 4,00,000 down payment - Total home budget about Rs 27,96,000.

Example 2 - Priya with an existing loan: Monthly income Rs 85,000, expenses Rs 25,000, an existing Rs 8,000 car EMI, FOIR 50% - net income Rs 60,000, total FOIR budget Rs 30,000, available for the home loan Rs 22,000. At 8.5% for 20 years the maximum home loan is far lower than if she had no car loan. This is exactly the existing-EMI adjustment most calculators miss.

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 a Rs 1 lakh salary and Rs 40,000 existing EMIs will get a much smaller home loan than someone with a Rs 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: The existing-EMI input in this calculator does this subtraction automatically. On an Rs 1,00,000 salary with an Rs 12,000 car loan EMI and 50% FOIR: maximum total EMIs = Rs 50,000. Available for the home loan = Rs 50,000 - Rs 12,000 = Rs 38,000.

LTV Ratio - How Much Will the Bank Actually Lend?

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

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

This means an Rs 80 lakh property requires at least Rs 20 lakh down payment - the bank lends a maximum of Rs 60 lakh regardless of your affordability calculation. Always validate your affordability estimate against the required minimum down payment for your target property bracket. The Required Min Down Payment insight in this calculator shows the exact amount you must save for the property you can afford, and flags the shortfall if your current down payment is too low.

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%). Women buyers get a 1-2% concession in several states.
  • 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. On a Rs 40 lakh loan, that is Rs 10,000-40,000
  • Interior or renovation: Rs 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 Rs 50,000 to Rs 5,00,000
  • Legal and conveyance charges: Rs 10,000-30,000 for title verification, property evaluation, and documentation

A realistic budget should account for: down payment + stamp duty + registration + GST (if applicable) + processing fees + interior renovation buffer. For a Rs 60 lakh property, total initial outgo before you move in could reach Rs 20-25 lakh including loan costs. Do not commit your entire savings to the down payment and have nothing left for these essential expenses.

Understanding the Insights and Breakdown

Beyond the headline numbers, this calculator gives you a few quick-read figures:

  • Net Monthly Surplus: Your income minus expenses - the money you have each month before EMIs. This is the pool from which your home loan EMI is drawn.
  • EMI Is of Gross Income: The percentage of your full monthly income that the home loan EMI takes. A lower figure means the EMI is easy to manage; a figure near 30% or more is a heavy load on your gross earnings.
  • Home Loan vs Annual Income: How many times your annual income your maximum home loan represents - commonly 3 to 7 times. This is a quick sanity check against typical bank eligibility multiples.
  • Property vs Annual Income: The same multiple but for the full property price including your down payment.
  • Required Min Down Payment: The least cash you must put down for the property you can afford, based on the RBI LTV bracket for that price.
  • Down Payment Shortfall: Shown only when your down payment is below the required minimum - the extra cash you need to save before buying.
  • Tenure Comparison: A table showing how the EMI, total interest, and total payment on your maximum loan change at 10, 15, 20, 25, and 30-year tenures.

Frequently Asked Questions About Home Loan Affordability

A bank's eligibility calculator tells you the maximum it will sanction based on its 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, any existing EMIs, and the adjustable 40-50% FOIR guideline. Banks can sometimes approve more than you can comfortably repay; this calculator provides a more conservative, practical ceiling. The gap between what a bank will lend and what you should borrow can be 20-30% - that is the financial safety margin this tool helps you maintain.
Because a bank counts all your fixed EMI obligations together against the FOIR ceiling. If your net income is Rs 60,000 and FOIR is 50%, the total of all your EMIs cannot comfortably exceed Rs 30,000. If you already pay an Rs 8,000 car EMI, only Rs 22,000 is left for the home loan. Most affordability calculators ignore this and overstate your loan by exactly the amount of your existing EMIs, then divided across the loan. Enter your existing EMIs here to get a number a bank would actually approve.
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 under the old regime. 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%, half your net income is committed to EMIs - any income disruption (job loss, medical emergency) immediately threatens repayment. At 40%, you have a meaningful cushion. If you have young children with high education costs ahead, existing car or personal loans, or a variable-income job, target 35-40%. If you have stable dual income, no other loans, and strong emergency savings, 45-50% is manageable. This calculator lets you slide the FOIR and see exactly how much loan each target supports.
LTV (Loan-to-Value) caps how much of a property a bank will lend you. Under RBI rules, up to Rs 30 lakh the bank can lend 90%; from Rs 30-75 lakh, 80%; above Rs 75 lakh, 75%. The rest must come from your down payment. If your income allows you to afford a Rs 40 lakh property but your down payment is only Rs 4 lakh (10%), you are below the 20% minimum for that bracket. The calculator shows the exact required minimum and the shortfall, so you know how much more to save before you buy.
Financially yes - a larger down payment reduces the loan principal, saving total interest and reducing the monthly EMI. However, it only makes sense if: (1) you will not drain your emergency fund (keep 6 months of expenses liquid), and (2) the funds are not 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.
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 can get up to a 35-year tenure; a 45-year-old is typically restricted to 15-20 years. Shorter available tenure means a higher mandatory EMI for the same loan amount - reducing affordability for older applicants. Adding a younger co-applicant can extend the tenure and improve affordability. Adjust the tenure slider in this calculator to see how a shorter tenure lowers your maximum loan.
Start by identifying the property price range you are targeting and calculating the required down payment (20-25% based on LTV rules). Factor in stamp duty, registration, and other upfront costs - typically an additional 7-10% of property value. If you need Rs 15 lakh for down payment and registration on a Rs 60 lakh property and you currently save Rs 25,000 a month, you need approximately 60 months (5 years). Running this calculator at different down payment amounts helps you see the EMI trade-off and decide your target savings timeline. Starting a dedicated home fund SIP 3-4 years before your planned purchase is one of the most effective strategies.

Always confirm the exact FOIR cap, LTV rules, interest rates, and down payment requirement with your lender, since these vary between banks and change with RBI policy. This calculator gives financial projections for planning and is not a substitute for professional financial advice.
