Business Loan EMI Calculator: Formula, Examples and Hidden Costs

A business loan EMI calculator works out your monthly instalment from three inputs: the loan amount, the annual interest rate and the tenure. A ₹10 lakh business loan at 16% for 3 years costs ₹35,157 a month, and you pay ₹2,65,653 in interest over the term. You can run your own numbers on our business loan EMI calculator.

Key facts

How the business loan EMI formula works

Every EMI calculator, whether on a bank’s site or ours, uses the same reducing-balance formula. Each instalment pays the interest due for that month first, and the rest goes towards principal.

1. Take the loan amount (P). For a ₹10 lakh loan, P is 10,00,000.
2. Divide the annual rate by 12 and by 100 to get the monthly rate (r). At 16% a year, r is 0.013333.
3. Convert the tenure into months (n). Three years is 36 months.
4. Put the three values into EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1).
5. Multiply the EMI by n and subtract P to get the total interest.

In the early months most of each EMI is interest. As the balance falls, the interest part shrinks and more of the EMI repays principal. A loan amortisation table shows this month by month; you can build one with the amortisation calculator.

Business loan EMI examples

The figures below use the standard formula with a fixed rate for the whole term. They are illustrations, not offers from any lender.

How tenure changes your EMI and total cost

A longer tenure lowers the monthly EMI but raises the interest you pay. On a ₹10 lakh loan at 16%:

Stretching from 2 to 4 years cuts the EMI by ₹20,623 a month but adds ₹1,85,218 of interest. Pick the shortest tenure your monthly cash flow can carry, keeping a margin for slow months. RBI sets no fixed EMI-to-income ratio for business loans; each lender applies its own test to your bank statements, returns and turnover.

Using a lender’s calculator, such as Credit Saison’s

Lender calculators use the same formula but often open with a preset rate. Credit Saison India is the brand of Kisetsu Saison Finance (India) Private Limited, an NBFC registered with the RBI. Its business loan page lists rates starting at 16%, amounts up to ₹50 lakh and tenures of 12 to 48 months. Its small business loan page starts at 21%, and its loan calculator opens at 21% for 12 months.

“Starts at” is the lowest rate the lender offers. Your own rate depends on your credit score, business vintage, turnover and existing debt. Enter the rate in your sanction letter or Key Facts Statement, not the headline rate, to get your real EMI. Our business loan interest rates page compares lenders’ published ranges.

Costs the EMI figure leaves out

The calculator shows interest only. Before you sign, add these to the cost:

The Key Facts Statement must show the annual percentage rate, which folds these charges into one figure. Compare that number across offers rather than the interest rate alone.

Floating rates, repo changes and prepayment

Floating-rate bank loans to micro and small enterprises have been linked to an external benchmark, usually the repo rate, since 1 October 2019. The repo rate is 5.25%, and the RBI’s next decision follows its 5–7 October 2026 meeting. If your benchmark moves, your lender will change either the EMI or the tenure at the next reset.

RBI’s Pre-payment Charges Directions, 2025 cover loans sanctioned or renewed on or after 1 January 2026. Commercial banks (other than small finance, regional rural and local area banks), large NBFCs and all-India financial institutions cannot charge for prepaying a floating-rate business loan taken by an individual or a micro or small enterprise. Small finance banks, regional rural banks, some co-operative banks and middle-layer NBFCs cannot charge on such loans sanctioned up to ₹50 lakh. Fixed-rate loans follow the lender’s policy, which must be disclosed upfront.

Since 1 April 2026, banks cannot ask for collateral on micro and small enterprise loans up to ₹20 lakh. For larger unsecured needs, government-backed routes are listed in our guide to government business loan schemes.

Is business loan interest tax-deductible?

Interest on money borrowed for your business is generally allowed as an expense when you compute business income. The principal part of the EMI is not an expense. From tax year 2026-27 the Income-tax Act, 2025 applies; returns for FY 2025-26 are still filed under the Income-tax Act, 1961. A chartered accountant can confirm how this applies to your accounts.
