Home Loan EMI Calculator — EMI, Total Interest & Prepayment Savings
A ₹60 lakh loan at 8.5% for 20 years costs ₹65 lakh in interest — more than the principal. The same loan with a modest extra payment each month ends years earlier and lakhs cheaper. This calculator shows your EMI, the true total cost, and exactly what prepayment saves — the number banks don't advertise.

EMI = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1), monthly rate r = annual ÷ 12. Floating-rate loans from banks have no prepayment penalty for individuals.

What an EMI Is Made Of
Every EMI is part interest, part principal — but the mix changes over time. In year one of a 20-year loan at 8.5%, roughly 70% of each EMI is interest; by year 15 it flips. This is why prepaying early in the tenure is so powerful: every rupee of early prepayment kills 20 years of compounding interest on that rupee.

No penalty: RBI rules prohibit prepayment penalties on floating-rate loans to individuals — every Indian bank home loan qualifies.
Ask for tenure reduction, not EMI reduction, when you prepay a lump sum — it saves far more interest.
Tax angle (old regime): §24(b) gives up to ₹2L deduction on interest and §80C covers principal within ₹1.5L. Heavy prepayment reduces these deductions — usually still worth it, but run both regimes in our income tax calculator.
Frequently Asked Questions
At 8.5% for 20 years: ₹43,391/month, with total interest of about ₹54.1 lakh. At 15 years the EMI rises to ₹49,237 but total interest drops to ₹38.6 lakh — shorter tenures cost more monthly but far less overall.
No — the RBI bars banks and NBFCs from charging prepayment penalties on floating-rate loans to individual borrowers, and nearly all Indian home loans are floating-rate. Fixed-rate loans may carry charges of about 2–3%.
Reduce tenure. Keeping the same EMI and shortening the loan saves several times more interest than lowering the monthly payment. Reduce the EMI only if you genuinely need monthly cash-flow relief.
A 30-year loan lowers the EMI (improving eligibility) but can double your total interest. If you can afford the 20-year EMI, take it — or take 30 years for safety and prepay aggressively, which mimics a shorter tenure with flexibility.
Old regime: up to ₹2 lakh/year deduction on interest (§24(b)) for self-occupied property, plus principal repayment within the ₹1.5 lakh §80C limit, plus stamp duty in the purchase year. New regime: none of these for self-occupied homes — which is why heavy-deduction borrowers should compare regimes before defaulting to the new one.
