How to Calculate EMI on a Home Loan in India (2026)
Buying a home is one of the biggest financial decisions of your life — and your monthly EMI will stay with you for 10 to 30 years. Before you sign anything, you need to know exactly how much you'll pay every month, how much of it is interest, and how your tenure choice changes everything.
This guide breaks it all down in plain language, with the formula, a worked example, and a free calculator you can use right now.
What is an EMI?
EMI stands for Equated Monthly Instalment. It is the fixed amount you pay your bank or housing finance company every month until your loan is fully repaid. Each EMI contains two parts: a portion that repays the principal (the actual loan amount) and a portion that pays the interest.
In the early months of a loan, most of your EMI goes toward interest. As years pass, more and more of it goes toward the principal. This is called an amortising loan.
The EMI Formula
Where:
P = Principal loan amount
r = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
n = Loan tenure in months
This looks complex but your bank uses this exact formula for every home loan in India. Let's walk through a real example.
Worked Example
Say you take a home loan of ₹50 lakhs at an interest rate of 8.5% per annum for a tenure of 20 years.
- P = ₹50,00,000
- Annual rate = 8.5%, so monthly rate r = 8.5 ÷ 12 ÷ 100 = 0.007083
- n = 20 × 12 = 240 months
Plugging into the formula: EMI ≈ ₹43,391 per month
Over 20 years, you pay ₹43,391 × 240 = ₹1,04,13,840 total. Your interest payout alone is ₹54,13,840 — more than the original loan amount.
How Tenure Affects Your EMI
One of the most powerful decisions you make is choosing your loan tenure. Here's how EMI changes for a ₹50 lakh loan at 8.5%:
| Tenure | Monthly EMI | Total Interest Paid |
|---|---|---|
| 10 years | ₹61,993 | ₹24,39,160 |
| 15 years | ₹49,239 | ₹38,63,020 |
| 20 years | ₹43,391 | ₹54,13,840 |
| 25 years | ₹40,260 | ₹70,78,000 |
| 30 years | ₹38,446 | ₹88,40,560 |
A longer tenure lowers your monthly burden but massively increases total interest. A 30-year loan costs you ₹64 lakh more in interest than a 10-year loan on the same principal.
How Interest Rate Affects Your EMI
Even a small rate change can add up to lakhs over the life of a loan. Here's the impact on a ₹50 lakh, 20-year loan:
| Interest Rate | Monthly EMI | Total Interest |
|---|---|---|
| 7.5% | ₹40,280 | ₹46,67,200 |
| 8.0% | ₹41,822 | ₹50,37,280 |
| 8.5% | ₹43,391 | ₹54,13,840 |
| 9.0% | ₹44,986 | ₹57,96,640 |
| 9.5% | ₹46,607 | ₹61,85,680 |
Negotiating even 0.5% off your interest rate on a ₹50 lakh loan saves you over ₹3.7 lakh across 20 years.

Frequently Asked Questions
Does my EMI change if the RBI changes interest rates?
If you have a floating rate home loan (most home loans in India are floating), your EMI or tenure can change when your bank revises its benchmark rate (EBLR or MCLR). Your bank will notify you of any change.
Can I reduce my EMI mid-loan?
Yes. You can make a part-prepayment to reduce your outstanding principal, after which your bank will either reduce your EMI or reduce your remaining tenure. Most banks allow prepayment without charges on floating rate home loans.
Is home loan EMI tax deductible in India?
Yes. Under Section 24(b) of the Income Tax Act, you can claim a deduction of up to ₹2 lakh per year on the interest portion of your home loan EMI. The principal portion is eligible for deduction under Section 80C up to ₹1.5 lakh annually.
