What is the Home Loan Affordability Calculator?
This calculator estimates an income-supported home-loan amount from the monthly take-home income, existing EMIs, annual interest rate, tenure and EMI-to-income percentage you enter. It is a planning illustration, not a lender eligibility or approval result.
The output does not model a target property price, down payment, stamp duty, registration, lender-specific underwriting, credit score, loan-to-value limits or scheme eligibility. Review those items separately before making a purchase decision.
How does it work?
The calculator first multiplies monthly take-home income by the entered EMI percentage and subtracts existing EMIs. It then reverses the standard EMI formula to estimate the loan principal supported by the remaining monthly EMI amount at the entered rate and tenure.
The EMI percentage is your scenario input. It is not a universal FOIR limit and does not represent any lender's policy. A lender may use different income definitions, obligations, credit checks and underwriting rules.
Worked example
For an illustrative take-home income of ₹80,000, existing EMIs of ₹10,000 and an entered EMI percentage of 45%, the available monthly amount is ₹26,000. The calculator converts that amount into an estimated loan principal using the entered interest rate and tenure. Change one input at a time to compare scenarios; the result remains a mathematical estimate, not a property budget or sanction amount.
When to use this calculator
- 1Compare the loan estimate produced by different EMI-percentage assumptions.
- 2See how an existing EMI changes the monthly amount available in the illustration.
- 3Compare interest-rate or tenure scenarios using the same income assumptions.
Common mistakes to avoid
- ✕Reading the estimate as lender eligibility, approval or a guaranteed sanction amount.
- ✕Treating the estimated loan amount as a complete property budget when down payment and purchase costs are not inputs.
- ✕Using a single rate or tenure scenario without testing how the estimate changes.
Frequently asked questions
- Does this show whether a lender will approve my loan?
- No. It is an income-supported mathematical estimate. Each lender applies its own underwriting, income, obligation, credit and property rules.
- Does this calculate the property price or down payment?
- No. Property price, down payment, loan-to-value limits and purchase costs are outside this calculator.
- What does the EMI percentage mean?
- It is the share of take-home income you choose for this scenario before existing EMIs are subtracted. It is not a lender-specific FOIR decision or a recommendation.
