EMI Calculator

All Indian banks use the reducing-balance formula: EMI = P × r × (1+r)ⁿ ÷ [(1+r)ⁿ − 1], where P is the principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the number of monthly instalments. Interest is recalculated each month on the outstanding balance — not the original loan amount. As a result, the interest component shrinks every month while the principal component grows, keeping the total EMI constant.

For a plain loan at a constant rate with no additional fees, an EMI calculator matches your bank's figure to the rupee. Minor differences can arise because processing fees and GST are not included, some loans have a partial-month first EMI, and floating-rate loans will have future rate revisions that cannot be predicted. Use a calculator for planning and comparison — confirm the exact figure with your bank's loan sanction letter before signing.

Longer tenure reduces the monthly EMI but significantly increases total interest paid. The trade-off is linear in one direction — the EMI falls — but exponential in the other — total interest rises steeply. Choosing the longest available tenure to minimize monthly outflow can result in paying substantially more than the original loan amount in interest alone. Always calculate total payment (EMI × months) alongside the monthly figure when evaluating tenure options.

The interest rate has a compounding effect on total loan cost — even a small rate difference magnifies across a long tenure. On a large, long-tenure loan, a 0.5% rate difference can mean several lakh rupees in additional interest over the loan's life. This is why comparing offers from multiple lenders and negotiating the rate before signing is one of the most impactful steps a borrower can take.

An amortization schedule is a complete payment-by-payment breakdown of a loan, showing how each EMI is split between principal repayment and interest. Because interest is calculated on the outstanding balance, this split shifts every month — the interest share is highest in Month 1 and lowest in the final month. The schedule reveals the true cost of different tenure choices and, for home loan borrowers on the old tax regime, gives the annual interest figure needed for Section 24(b) deductions.

Every prepayment reduces the outstanding principal, which immediately lowers the interest charged for every remaining month. The earlier a prepayment is made, the more months it saves interest on — a ₹1 lakh prepayment in the third month of a 20-year loan removes interest on that amount for approximately 237 months. The same amount prepaid in Month 200 saves interest for only 40 months. This compounding effect is why early prepayment is significantly more effective than later prepayment.

Reducing tenure saves significantly more money. When tenure reduces, the balance clears faster and interest savings compound over fewer remaining months. With EMI reduction, the tenure stays the same — you pay less monthly but the loan does not close earlier and total interest saved is lower. The only valid reason to choose EMI reduction is if the current monthly payment is genuinely straining your cash flow.

For floating-rate loans linked to the repo rate or EBLR, your bank adjusts either the EMI or the tenure when rates change. Banks often prefer to extend tenure rather than raise EMI, which can quietly add months — and significant interest — to your loan without changing your monthly outflow. Always clarify with your lender which variable will be adjusted when rates move, and check your loan statement periodically if you are on a floating rate.

No — for floating-rate home loans, banks are prohibited from charging prepayment or foreclosure penalties under RBI circular DBOD.No.Dir.BC.56/13.03.00/2011-12. Most home loans are on floating rates linked to the repo rate, so this protection applies to the majority of borrowers. Fixed-rate loans are not covered by this rule and may carry foreclosure charges. Always check your specific loan agreement's foreclosure clause before making a large prepayment.

Under the flat-rate method, interest is calculated on the original loan amount throughout the tenure — even as you repay principal. Under the reducing-balance method, interest is recalculated each month on the outstanding balance only. A flat rate of 12% is roughly equivalent to 21–22% on a reducing-balance basis for typical multi-year tenures, though the exact gap narrows for shorter tenures. All RBI-regulated bank loans use the reducing-balance method. Always ask for the reducing-balance APR when comparing loan offers from different sources.

The EMI calculation itself — based on principal, rate, and tenure — is identical for both. What differs is eligibility and the rate offered: lenders typically assess self-employed applicants using income tax returns and bank statements over 2–3 years rather than a salary slip, and may apply a marginally higher rate or lower loan-to-value to account for income variability. The EMI figure this calculator produces is accurate for either borrower type once the loan is sanctioned.
