Business Loan Calculator Guide: Check EMI, Interest and Total Cost
A business loan can help you expand operations, purchase equipment, manage working capital or invest in new opportunities. However, before applying, it is important to understand how much you will repay every month and how much the loan will cost over its entire tenure. A business loan calculator helps you estimate your monthly EMI, total interest payable and overall repayment amount based on the loan amount, interest rate and repayment period. By calculating these costs in advance, you can plan your business finances more effectively, compare loan options and choose a repayment plan that fits your budget.
How to use the business loan calculator
Use LoanQuantum's free business loan EMI calculator to see your monthly instalment, the total interest and the true cost of the loan once fees are included, before you apply. Enter the loan amount, interest rate and tenure. You'll see your EMI schedule instantly.
Quick example: A ₹10 lakh business loan at 15% p.a. for 3 years has an EMI of ₹34,665. You pay ₹2,47,952 in interest and ₹12,47,952 in total.
- Enter the loan amount: Type or slide to the amount you need, from ₹50,000 up to ₹2 crore.
- Enter the interest rate: Use the rate quoted by your lender. If you don't have a quote yet, see the indicative rates below.
- Choose the tenure: Pick the repayment period in months (12–60 months is typical for unsecured business loans).
You'll instantly see your monthly EMI, total interest, total amount payable and a month-by-month amortisation schedule.
How is business loan EMI calculated?
Business loan EMIs in India are calculated on a reducing-balance basis using this formula:
EMI = P × R × (1 + R)ⁿ ÷ [(1 + R)ⁿ − 1]
- P = principal (loan amount)
- R = monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = tenure in months
Example: ₹10,00,000 at 15% p.a. for 36 months
- R = 15 ÷ 12 ÷ 100 = 0.0125
- n = 36
- EMI = 10,00,000 × 0.0125 × (1.0125)³⁶ ÷ [(1.0125)³⁶ − 1] = ₹34,665
- Total payable = ₹34,665 × 36 = ₹12,47,952, so total interest = ₹2,47,952
Doing this by hand or in Excel (=PMT(15%/12,36,-1000000)) is easy to get wrong. The calculator does it instantly and accurately.

Example of Business loan EMI per ₹1 lakh Rupees
| Interest rate | 1 year | 2 years | 3 years | 4 years | 5 years |
|---|---|---|---|---|---|
| 12% | ₹8,885 | ₹4,707 | ₹3,321 | ₹2,633 | ₹2,224 |
| 14% | ₹8,979 | ₹4,801 | ₹3,418 | ₹2,733 | ₹2,327 |
| 16% | ₹9,073 | ₹4,896 | ₹3,516 | ₹2,834 | ₹2,432 |
| 18% | ₹9,168 | ₹4,992 | ₹3,615 | ₹2,937 | ₹2,539 |
| 20% | ₹9,263 | ₹5,090 | ₹3,716 | ₹3,043 | ₹2,649 |
Multiply by your loan size in lakhs. For example, ₹15 lakh at 16% for 3 years ≈ 15 × ₹3,516 = ₹52,740/month.
What affects your business loan EMI?
1. Loan amount: EMI rises in direct proportion to the amount. Borrow what the business needs, not the maximum offered.
2. Loan Interest rate: Every 2 percentage points adds roughly ₹1,000/month on a ₹10 lakh, 3-year loan:
| Rate (₹10 lakh, 3 yrs) | EMI | Total interest |
|---|---|---|
| 12% | ₹33,214 | ₹1,95,715 |
| 14% | ₹34,178 | ₹2,30,395 |
| 16% | ₹35,157 | ₹2,65,653 |
| 18% | ₹36,152 | ₹3,01,486 |
| 20% | ₹37,164 | ₹3,37,889 |
3. Loan Tenure: An extended loan duration reduces the monthly installment amount; however, it correspondingly elevates the aggregate interest expense incurred over the loan's lifetime.
| Tenure (₹10 lakh @ 15%) | EMI | Total interest | Total payable |
|---|---|---|---|
| 12 months | ₹90,258 | ₹83,100 | ₹10,83,100 |
| 24 months | ₹48,487 | ₹1,63,680 | ₹11,63,680 |
| 36 months | ₹34,665 | ₹2,47,952 | ₹12,47,952 |
| 48 months | ₹27,831 | ₹3,35,876 | ₹13,35,876 |
| 60 months | ₹23,790 | ₹4,27,396 | ₹14,27,396 |
Indirect factors set the rate you're offered: your CIBIL score, business vintage, turnover and GST filing history, existing debt, and whether the loan is secured or unsecured.
Business loan amortisation schedule
An amortisation schedule shows how each EMI splits between interest and principal, and what you still owe after every payment. Interest is charged on the outstanding balance, so early EMIs are mostly interest, and later EMIs are mostly principal.
Yearly schedule: ₹10 lakh at 15% for 3 years (EMI ₹34,665)
| Year | Principal paid | Interest paid | Balance at year-end |
|---|---|---|---|
| 1 | ₹2,85,054 | ₹1,30,930 | ₹7,14,946 |
| 2 | ₹3,30,878 | ₹85,106 | ₹3,84,068 |
| 3 | ₹3,84,068 | ₹31,916 | ₹0 |
In excess of fifty percent of the aggregate interest accrues during the initial year. That's why prepaying your loan early saves the most. Use the calculator to view and download the full month-by-month schedule.
Interest rate vs the true cost of a business loan
The headline interest rate isn't the full cost. Indian lenders typically charge:
- Processing fee: usually 1–4% of the loan amount, often deducted from the disbursal
- 18% GST on the processing fee and other charges
- Other charges: documentation/stamp duty, late-payment penalties, and foreclosure/part-payment fees (commonly 2–5% of the outstanding balance on unsecured loans, depending on the lender)
Example: On ₹10 lakh at 15% for 3 years with a 2% processing fee, you pay ₹20,000 + ₹3,600 GST = ₹23,600 upfront. You receive ₹9,76,400 but repay EMIs on ₹10 lakh, so your effective annual rate is about 16.7%, not 15%. It is advisable to consistently evaluate all available offers based on their annual percentage rate (APR), which serves as the most reliable metric for comparison.
Flat rate vs reducing balance rate
Some lenders and DSAs quote a flat rate, where interest is charged on the full original amount for the whole tenure. That makes the rate look much lower than it really is.
- 10% flat on ₹10 lakh for 3 years = EMI of ₹36,111
- The same EMI on a reducing balance works out to about 17.9% p.a.
If you're quoted a flat rate, ask for the reducing-balance equivalent. This calculator uses the reducing-balance method, which is the standard regulated lenders use.
Indicative business loan interest rates in India (2026)
| Lender type | Typical rate (p.a.) | Typical processing fee | Best for |
|---|---|---|---|
| Public & private sector banks | ~10% – 20% | 0.5% – 2% | Established businesses, strong CIBIL, secured loans |
| NBFCs | ~14% – 26% | 1% – 3% | Faster approval, moderate documentation |
| Fintech / digital lenders | ~16% – 30%+ | 2% – 4% | Small-ticket, quick, collateral-free loans |
| Government schemes (e.g. CGTMSE-backed, MUDRA) | Linked to bank rates | Low / nil | Micro & small enterprises |
Rates are indicative and change frequently. Your rate depends on your profile. Compare the loan offers on LoanQuantum.
How your EMI affects loan approval (FOIR)
Lenders check your Fixed Obligation to Income Ratio (FOIR):
FOIR = (all monthly EMIs, including the new one ÷ net monthly income) × 100
Most lenders want FOIR at or below 50–65%.
Example: Your business's net monthly income is ₹2,00,000, and you already pay ₹40,000 in EMIs. At a 50% FOIR limit, you have room for ₹60,000 more in EMIs. At 15% for 3 years, that supports a loan of about ₹17.3 lakh.
Use a calculator in reverse: determine the equated monthly installment that aligns with your financial capacity, subsequently modifying the principal amount and loan duration to ensure the installment remains within your comfortable payment range. For a turnover-based estimate, see how much business loan you can get on your monthly turnover.
Prepayment and foreclosure: how much can you save?
Paying part of the loan early reduces your outstanding principal, and therefore the interest charged on it.
Example: On the ₹10 lakh, 15%, 3-year loan, you prepay ₹2 lakh after 12 EMIs and keep the same EMI:
- Loan closes in 29 months instead of 36
- Total interest falls from ₹2,47,952 to about ₹1,89,232, a saving of ₹58,719 (before any part-payment fee)
Check your lender's part-payment and foreclosure terms first. Some unsecured business loans charge a fee or lock prepayment for the first 6–12 months.

7 ways to lower your business loan EMI
- Improve your CIBIL score to 750+ before applying. This is your rate's largest lever.
- Compare at least 3 offers on the effective rate (APR), not the headline rate.
- Borrow only what you need. Calculate the loan's size based on its purpose.
- Choose the tenure carefully. A longer tenure lowers the EMI but raises the total interest, so pick the shortest tenure your cash flow can handle.
- Offer collateral if you can. Secured loans normally have a lower rate.
- Prepay early when you have surplus cash, because early EMIs are interest-heavy.
- Consider a balance transfer if another lender offers a meaningfully lower rate, after accounting for fees.
Loan Eligibility and Documents Checklist
Typical eligibility: applicant aged 21–65, business vintage of 1–3 years, stable turnover with regular GST filings, and a CIBIL score of around 700+ (some NBFCs accept 650–675). Requirements vary by lender.
Common required documents: PAN and Aadhaar of the owners, GST registration and returns (6–12 months), bank statements (6–12 months), business proof (Udyam/MSME certificate, Shop Act or partnership deed), and ITR with financials for the last 1–2 years for larger loans.
