Home-loan EMI & the Repo Rate

Most Indian home loans track the RBI repo rate (currently 5.25%): your rate is the repo rate plus your bank’s margin. Drag the sliders to see your EMI — and exactly what one RBI rate move (±0.25%) would do to it.

How your home loan EMI is calculated

Your EMI (Equated Monthly Instalment) is the fixed monthly payment that clears your loan over its tenure. It is computed with the standard reducing-balance formula:

EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)

P — the loan amount (principal).
r — the monthly interest rate = annual rate ÷ 12 ÷ 100.
n — the tenure in months (years × 12).

Early EMIs are mostly interest; as the outstanding balance shrinks, a larger share of each payment goes towards principal. The breakdown bar above shows how much of your total outgo over the full loan is principal versus interest.

Why the RBI repo rate moves your EMI

Since October 2019, new floating-rate home loans must be linked to an external benchmark, and for most banks that benchmark is the RBI repo rate (currently 5.25%). Your loan rate is simply the repo rate plus your bank’s margin. So when the RBI’s Monetary Policy Committee changes the repo rate, your rate — and your EMI — resets to match, typically within one to three months.

That is why the calculator shows your EMI at the current rate and at ±0.25%: one repo move is usually a quarter-point. To track the repo rate itself, the MPC meeting calendar and the full rate history, see our RBI policy rates page.

Frequently Asked Questions

What is a home loan EMI?

EMI stands for Equated Monthly Instalment — the fixed amount you pay your lender every month until the loan is repaid. Each EMI has two parts: interest on the outstanding balance and repayment of principal. In the early years most of the EMI is interest; as the balance falls, more of each EMI goes towards principal.

How is home loan EMI calculated?

EMI is calculated with the formula EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount (principal), r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the tenure in months. The calculator on this page applies this formula instantly as you change the loan amount, tenure or interest rate.

How does the RBI repo rate affect my home loan EMI?

Since October 2019, new floating-rate retail loans from banks are linked to an external benchmark — for most home loans that benchmark is the RBI repo rate. Your loan rate is the repo rate plus a fixed margin set by your bank, so your effective rate is roughly 5.25% (today's repo) plus about 2% to 3%. When the RBI changes the repo rate, your rate — and therefore your EMI or tenure — is reset to match, usually within one to three months.

How much does a 0.25% (25 bps) rate change affect my EMI?

A 25 basis-point (0.25%) move in your rate changes the EMI by roughly ₹190 to ₹230 per month for every ₹10 lakh of outstanding loan on a 20-year tenure. On a ₹50 lakh, 20-year loan that is about ₹750 a month either way. Use the "If the RBI moves the repo rate once" panel above to see the effect on your own numbers.

When rates fall (or I prepay), should I reduce my EMI or my tenure?

Keeping the EMI the same and reducing the tenure saves you far more interest overall, because you clear the principal faster. Reducing the EMI eases monthly cash flow but stretches the loan and costs more interest in total. Most borrowers who can afford the existing EMI are better off shortening the tenure.

Is this EMI calculator exact?

It gives an accurate estimate using the standard reducing-balance formula. Your actual EMI can differ slightly because of your bank's exact spread, how often your rate resets, processing fees, insurance, and any part-prepayments. Treat the figures as a close guide, not a quote.
