Business Loan Calculator
A business loan has three different rates and most calculators show you one. This shows all three: what the lender quotes, what the fees make it, and what it costs after the tax deduction that makes business debt different from personal debt.
The loan
What the lender takes off the top
Charged on the loan amount, and 18% GST applies on the fee itself.
Legal, valuation, stamping. Anything charged as a flat amount.
Your tax position
This is the part no other business loan calculator asks for, and it is the part that decides what the loan actually costs you.
Interest is a deductible expense, so every rupee of interest cuts your taxable profit.
Leave at 0 for working capital. If you are financing machinery, section 32(b)(i) denies the deduction until the asset is first put to use.
What it really costs you

- Monthly payment

- With fees inside it

- You actually receive
- ₹19,47,800
| Rate | Figure | Who shows it |
|---|---|---|
| Quoted by the lender | 14.00% | Everyone |
| With fees inside it | 15.19% | Better US tools |
| After the tax deduction | 10.58% | Nobody |
Fees add 1.19 points to the rate you were quoted, because you pay interest on ₹20,00,000 while only receiving ₹19,47,800. The deduction then takes 4.62 points back off, because interest and fees both reduce your taxable profit. The net of those two is the number in the result box, and it is the only one of the three that tells you what the borrowing actually costs.
| Interest over 5 years | ₹7,92,190 |
|---|---|
| Fees, including 18% GST on the processing fee | ₹52,200 |
| Total cost before tax | ₹8,44,390 |
| Tax saved on interest and fees | ₹2,53,317 |
| Cost after tax | ₹5,91,073 |
Deductibility is under section 32(b) of the Income-tax Act 2025, which replaced section 36(1)(iii) of the 1961 Act when that was repealed on 1 April 2026.
The after-tax figure assumes the business is profitable enough to use the deduction. A business making a loss carries it forward instead, so the relief arrives later or not at all, and the honest cost that year is the middle number rather than the bottom one. This also does not model a moratorium, a floating rate, prepayment charges, or any guarantee fee on a collateral-free scheme. A chartered accountant in India or a CPA in the US is the right person to confirm your own position.

Three rates, and only one matters
The rate a lender quotes, the rate including fees, and the rate after tax relief are three different numbers describing the same loan. Only the last one tells you what the borrowing costs.
On the figures this page opens with, a Rs 20,00,000 loan at a quoted 14% over five years, the rate including fees is 15.19% and the rate after tax is 10.58%. Fees add 1.19 points because you pay interest on the full amount while receiving about Rs 19,47,800. The deduction then takes 4.62 points back off.
The field splits neatly by country, and neither half arrives. The better American tools reach the middle number: calculator.net takes an origination fee, a documentation fee and other charges, then computes an effective rate properly. The Indian tools mostly take a rate and a tenure and stop, so they never leave the first number. Neither reaches the third.
The deduction nobody calculates
Interest on money borrowed for business is a deductible expense, so every rupee of interest reduces your taxable profit. That is the single largest difference between business debt and personal debt, and it is missing from every calculator we could find.
Nine calculator pages were fetched and read across both countries in August 2026, six Indian and three American. Every one returned zero mentions of after-tax cost, zero of tax shield, zero of interest deductibility. One of the six Indian pages belongs to a tax filing company.
In India the authority is section 32(b) of the Income-tax Act 2025, which replaced section 36(1)(iii) of the 1961 Act on 1 April 2026. In the United States business interest is deductible subject to the section 163(j) limitation, which exempts small businesses under a gross receipts test the IRS sets at $32 million of average annual gross receipts for 2026. Almost anyone reading this page sits well below that.
The exception that catches equipment buyers
Interest on money borrowed to buy an asset is not deductible until that asset is first put to use. Section 32(b)(i) excludes it for the whole period between drawdown and commissioning.
That is a real cost for anyone financing machinery. Shipping, installation, trial runs and certification can take months, and the interest running through them buys no tax relief at all.
On the figures here, a twelve month gap before the asset goes into use moves the after-tax rate from 10.58% to 12.20% and forfeits about Rs 78,000 of relief. At twenty-four months it reaches 13.42%, and Rs 1,43,545 of relief is gone. The calculator takes those months as an input, which nothing else does, for the straightforward reason that nothing else models the deduction in the first place.
What this calculator does not do
The after-tax figure assumes the business is profitable enough to use the deduction. A loss-making business carries the loss forward, so relief arrives later or not at all, and the honest cost for that year is the middle number rather than the bottom one.
It does not model a moratorium, which is common on Indian term loans, nor a floating rate, nor prepayment charges, nor any guarantee fee on a collateral-free scheme. On that last one, we could confirm that the CGTMSE guarantee ceiling has risen to Rs 10 crore and that the fee was reduced to a minimum of 0.37%, but not the full slab structure, so it is left out rather than guessed at.
It also takes your tax rate as an input rather than computing it. Company, LLP and proprietorship rates differ, and a proprietor's business income sits inside their personal slab. A chartered accountant in India or a CPA in the United States is the right person to confirm yours.
Pair this with the guide
For the repayment side of any loan, the loan calculator compares the same borrowing across three tenures, and the prepayment calculator shows what paying extra actually saves. If you are working out whether the business can support the repayment at all, the break-even calculator counts the fixed costs, including what you need to pay yourself.
Frequently asked questions
What does a business loan actually cost?
Less than the rate you were quoted, because interest is a deductible business expense. On a Rs 20,00,000 loan at a quoted 14% over five years, with a 2% processing fee and 18% GST on that fee, the rate including fees works out at 15.19%. After the tax deduction at a 30% business tax rate, the real cost is 10.58%. Those are three different numbers describing the same loan, and most calculators show only the first.
Is business loan interest tax deductible in India?
Yes. Interest paid on capital borrowed for the purposes of business or profession is deductible under section 32(b) of the Income-tax Act 2025, which replaced section 36(1)(iii) of the 1961 Act when that was repealed on 1 April 2026. There is one important exception: interest on money borrowed to acquire an asset is not deductible for the period between drawing the loan and the date the asset is first put to use.
Can a US business deduct loan interest?
Yes, subject to the limitation in section 163(j), which caps the deduction for business interest expense. That limitation does not apply to a small business meeting the gross receipts test in section 448(c), and the IRS puts the inflation-adjusted threshold at $32 million of average annual gross receipts for 2026. Almost anyone using a small business loan calculator sits well below that, so the deduction applies without restriction.
Why is the rate with fees higher than the rate quoted?
Because you pay interest on the full loan amount while receiving less than that. A 2% processing fee on a Rs 20,00,000 loan is Rs 40,000, plus Rs 7,200 of GST on the fee itself, plus any documentation charge. You receive about Rs 19,47,800 and repay as though you had borrowed Rs 20,00,000. On these figures that adds 1.19 percentage points to the effective rate, and the shorter the loan, the larger that effect.
Does GST apply to a loan processing fee in India?
Yes, at 18%, and it applies to the fee rather than to the loan. A 2% processing fee on Rs 20,00,000 is Rs 40,000, and the GST on it is Rs 7,200, so the real deduction from your drawdown is Rs 47,200 before any documentation charge. Business loan calculators routinely omit this, though it is small relative to the two larger omissions on this page.
What if my business is making a loss?
Then the after-tax figure overstates your benefit. A deduction is only worth anything against profit you actually have. A loss-making business carries the loss forward instead, so the relief arrives in a later year or not at all, and the honest cost for the current year is the middle number, the rate including fees, rather than the after-tax one.
How many business loan calculators show the after-tax cost?
None that we could find. Nine calculator pages were fetched and read across both countries in August 2026, six Indian and three American, and every one returned zero mentions of after-tax cost, tax shield or interest deductibility. One of the six Indian pages belongs to a tax filing company. The better American tools do reach an effective rate including fees, which the Indian ones mostly do not, but neither field takes the next step.
