How EMI is actually calculated

Every lender in India uses the same reducing-balance formula. Only the inputs differ:

EMI = P × r × (1+r)ⁿ ÷ [(1+r)ⁿ − 1]

where P is the principal, r is the monthly rate (annual rate ÷ 12 ÷ 100) and n is the tenure in months. On a ₹50,00,000 loan at 8.5% for 20 years, r = 0.00708 and n = 240, giving an EMI of roughly ₹43,391 — and total interest of about ₹54.1 lakh, more than the loan itself.

That last number is the one worth sitting with. Over a long tenure at Indian rates, total interest routinely exceeds the amount borrowed.

Why your early EMIs are almost all interest

The EMI stays constant but its split does not. Interest is charged on the outstanding balance, so at the start — when the balance is highest — most of the payment services interest. On the ₹50 lakh example above, the first EMI splits into ₹35,417 interest and just ₹7,974 principal. The crossover, where principal finally exceeds interest, arrives around year 12 of 20.

This is why prepaying early is worth far more than prepaying late, and why a balance transfer in year 15 saves much less than the headline rate difference suggests.

Prepayment: cut the tenure or cut the EMI?

When you prepay, most lenders let you choose. The two are not equivalent:

• Reduce tenure, keep the EMI. Saves dramatically more interest, because you stop paying it sooner. Choose this unless the monthly outflow is genuinely straining you.
• Reduce the EMI, keep the tenure. Improves monthly cash flow but you keep paying interest for the full term, so lifetime savings are much smaller.

Under RBI rules, floating-rate home loans to individual borrowers carry no prepayment or foreclosure penalty. Fixed-rate loans can, so check which you actually hold before planning a lump sum.

Tax benefits — and the regime that decides whether you get any

This is the single most misunderstood part of an Indian home loan, and most EMI calculators ignore it entirely.

• Old regime. Interest on a self-occupied property is deductible under Section 24(b) up to ₹2,00,000 a year. Principal repayment qualifies under Section 80C, within the combined ₹1,50,000 ceiling shared with EPF, PPF, life insurance and the rest.
• New regime (Section 115BAC — the default). Neither applies to a self-occupied home. Section 80C is unavailable, and the Section 24(b) interest deduction is restricted to let-out property only.

So if you are on the new regime and the property is your own residence, the tax saving people routinely factor into affordability is zero. Work out your effective cost both ways before assuming a deduction you may not be entitled to, and treat this as a starting point for a conversation with a chartered accountant rather than advice.

What actually sets your rate

Since October 2019 the RBI has required banks to link floating-rate retail loans to an external benchmark — for most lenders, the repo rate. Your rate is that benchmark plus a spread, and the spread is where lenders differ. It is driven by your credit score, income stability, the loan-to-value ratio, and whether you are salaried or self-employed.

Because the benchmark moves, a floating EMI is not fixed for the life of the loan. Most lenders absorb repo changes by extending tenure rather than raising the EMI, which quietly increases total interest — worth checking on your own statement rather than assuming.
