What is the Loan Affordability?
Affordability starts from your budget, not the bank's formula. A lender may approve an EMI of 50% of your income; whether you can live on the other half — while still saving — is a different question entirely.
This calculator subtracts your real living costs and the savings you intend to protect, then converts the genuine surplus into a loan amount. The result is usually smaller than your eligibility, and that gap is your safety margin.
Formula & worked example
Work forward from surplus, then discount it back into a loan:
Loan = Surplus × ((1 + i)N − 1) / (i × (1 + i)N)
Worked example: ₹90,000 income, ₹40,000 expenses, ₹15,000 savings you refuse to give up → surplus ₹35,000. At 9% over 15 years that supports about ₹34.5 lakh, with the EMI at 38.9% of income — manageable, but not comfortable.
How to use this loan affordability calculator
- Use your actual take-home, averaged over 3 months if it varies.
- Be honest about living expenses — check 3 months of statements rather than guessing.
- Set the savings you want to protect; treating savings as optional is how budgets break.
- Aim for the "Comfortable" verdict — an EMI under 30% of income survives job changes and rate rises.
Smart tips
- Keep total EMIs under 30% of take-home for genuine comfort; 40% is the outer limit before stress sets in.
- Stress-test at +2% interest. Floating loans reprice, and a comfortable EMI today can become tight in two years.
- Never count bonuses or variable pay as EMI-servicing income — they disappear exactly when you need them.
- Build a 6-month emergency fund before taking a big loan, not after. It is what prevents a missed EMI.
- The gap between eligibility and affordability is your margin of safety. Borrowing into that gap is the most common money mistake.
Frequently asked questions
How much EMI is too much?
Above 40% of take-home pay you have almost no room for emergencies, a rate rise or an income gap. Under 30% is genuinely comfortable.
Why is my affordable loan lower than my eligible loan?
Eligibility only subtracts existing EMIs. Affordability subtracts your real living costs and savings too, so it reflects what you can actually sustain.
Should I include my spouse's income?
Only if that income is stable and genuinely committed to the EMI. Adding it raises both eligibility and risk if either job changes.
What if my income is irregular?
Use the lowest of your last 6–12 months, not the average. Freelancers and business owners should also keep a larger emergency fund before borrowing.
Does the tenure change what I can afford?
It changes the loan size, not the monthly strain. A longer tenure buys a bigger loan for the same EMI but costs far more interest overall.
How much loan can I afford on my salary?
A common rule is to keep total EMIs within about 40–50% of net monthly income. On ₹40,000 that's roughly a ₹16,000–20,000 EMI — about ₹18–22 lakh over 20 years at ~9%, before counting any existing loans.
What costs should I budget before taking a loan?
Beyond the EMI, allow for the down payment, processing fees, insurance and running costs, and keep an emergency fund of 3–6 months' expenses so one lean month doesn't put repayment at risk.
