Free home-finance planning tool
Home loan affordability calculator
Build an indicative property budget from income, existing obligations and the finance assumptions you enter. A lender must separately assess eligibility and sanction.
Illustrative obligation comparison
Existing monthly debt reduces new EMI room
Each example uses ₹60,000 net income, a 40% entered ratio, 8.5% annual interest and 20 years. These are planning assumptions, not lender rules.
How to use the calculator
Build one transparent affordability scenario
- 01Enter stable net monthly income
Use the monthly income figure relevant to the borrower or joint-borrower scenario being tested.
- 02Add existing monthly obligations
Include the recurring debt payments you want the affordability estimate to account for.
- 03Set the planning assumptions
Enter the obligation ratio, annual interest rate and tenure for the scenario you want to compare.
- 04Review the estimate cautiously
Compare the indicative loan and maximum new EMI, then confirm real eligibility with the lender.
Calculation method
How the affordability estimate works
The calculator first limits total monthly obligations using the ratio you enter, then converts the remaining EMI room into an indicative loan amount.
Show the formula and assumptions
- Total monthly debt allowance = net monthly income × entered obligation ratio
- Maximum new EMI = greater of zero or debt allowance - existing monthly obligations
- Indicative loan = present value of the new EMI across the entered tenure and interest rate
- At 0% interest, indicative loan = maximum new EMI × number of months
Common questions
Home loan affordability calculator FAQs
Clear answers about income, obligations, FOIR assumptions and the limits of an indicative loan estimate.
What does FOIR mean in this calculator?
FOIR is the obligation ratio you choose for the estimate. It limits total monthly debt obligations to a percentage of the entered net income. Lenders may define income, obligations and acceptable ratios differently.
Why do existing obligations reduce the indicative loan?
The calculation first reserves room for the monthly obligations you enter. Only the remaining amount within the chosen ratio is used as the possible EMI for a new loan.
Is the indicative loan amount a lender approval?
No. It is a mathematical planning estimate from your inputs. A lender decides eligibility, sanctioned amount, rate, tenure, conditions and property acceptability.
What income should I enter?
Use a stable monthly net-income figure relevant to the lender scenario you are testing. Confirm what income components and co-applicant income the lender will actually accept.
Can I include a co-applicant income?
Only include it when you are intentionally testing a joint-income scenario. A lender still decides whether that income is eligible and how it is assessed.
What happens when obligations use all the entered ratio?
The calculator shows zero room for a new EMI and an indicative loan of zero. That is a result of the entered assumptions, not a lender decision.
