EMI Calculator India — How Loan EMI Is Calculated (FY 2025-26)
EMI (Equated Monthly Instalment) is the fixed amount you pay your lender every month until the loan is fully repaid. Each payment covers the interest on your outstanding principal plus a portion of the principal itself. As you repay, the interest component shrinks each month and the principal component grows — this is the reducing balance method used by all Indian banks.
The EMI Formula Explained
The standard formula is: EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the loan principal, r is the monthly interest rate (annual rate ÷ 1200), and n is the tenure in months. A ₹50 lakh home loan at 8.5% for 20 years gives a monthly EMI of approximately ₹43,391 — and total interest of over ₹54 lakh, nearly matching the principal itself. This is why tenure matters as much as rate.
Home Loan Tax Deductions (Old Tax Regime Only)
If you have a home loan, the Old Tax Regime offers two powerful deductions. Under Section 24(b), you can deduct up to ₹2 lakh per year on home loan interest for a self-occupied property. Under Section 80C, the principal repayment amount counts within the ₹1.5 lakh overall limit. Neither deduction is available under the New Regime. Use our Tax Calculator to compare both regimes and see if your home loan justifies staying on the Old Regime.
| Loan Type | Typical Rate (FY 2025-26) | Usual Tenure | Tax Benefit |
|---|---|---|---|
| Home Loan | 8.35% – 9.5% | 15–30 years | Sec 24(b) + 80C (Old Regime) |
| Car Loan | 8.5% – 11% | 3–7 years | None |
| Personal Loan | 11% – 18% | 1–5 years | None |
| Education Loan | 9% – 13% | 5–15 years | Sec 80E — both regimes, no ceiling |
Prepayment — Should You Do It?
Prepayments in the early years of a loan save the most money — because the outstanding principal is highest when you begin, and interest is calculated on that balance. Even a single extra EMI per year can cut 2–4 years off a 20-year home loan. Most Indian banks allow prepayment without penalty on floating rate loans (mandated by RBI since 2012). Use our SIP Calculator to model the invest-vs-prepay comparison.
Frequently Asked Questions
Common questions about EMI calculation, home loans, and loan amortization.
EMI = P × r × (1+r)^n / ((1+r)^n − 1), where P = principal, r = monthly interest rate (annual rate ÷ 1200), and n = tenure in months. The reducing balance method means interest is charged only on the outstanding principal each month — so your interest component shrinks with every payment, while the principal component grows.
Home loan rates in India range from 8.35% to 9.5% p.a. in FY 2025-26, depending on the lender, your credit score, and whether the rate is fixed or floating. Most banks offer floating rates linked to EBLR or RLLR benchmarks that move with RBI repo rate changes. Fixed rates run about 1–2% higher.
Yes, under the Old Tax Regime only. Section 24(b) allows up to ₹2L per year on home loan interest for a self-occupied property. Section 80C allows the principal repayment amount within the ₹1.5L overall limit. Neither is available under the New Regime. Education loan interest is deductible under Section 80E with no ceiling for up to 8 years — and this works in both regimes.
For floating rate home loans, most Indian banks keep the EMI amount constant and adjust the tenure instead when rates change. A 0.5% rate hike on a ₹50L, 20-year loan can silently add 2–3 years to your repayment timeline without changing the monthly amount. Ask your bank which method they use — some do increase the EMI instead.
Generally yes, especially in the first half of the tenure when the interest component is highest. Even one extra EMI annually can save 2–4 years on a 20-year loan. Most banks allow prepayment without penalty on floating rate home loans (RBI mandated). Compare your loan rate against potential investment returns — if investments earn more, invest the surplus instead of prepaying.
