A loan advert leads with one number, the interest rate. That number is real, but it is only the largest part of the bill. A first-time borrower can compare two offers on rate alone and end up with the more expensive one.
The fix is simple arithmetic. You need the amount you will receive, the amount you will pay back, and the time in between.
What goes into the bill
| Cost | When you pay it | Where to find it |
|---|---|---|
| Interest | Inside every EMI | Sanction letter, repayment schedule |
| Processing fee | Usually deducted before the money is paid out | Key Facts Statement |
| GST on fees | With the fee. Commonly 18% as of November 2026, but check your statement | Key Facts Statement or fee receipt |
| Insurance or other third-party costs | Often at the start, if you agree to them | Key Facts Statement, shown separately |
| Late payment and bounce charges | Only if an EMI is missed | Key Facts Statement |
| Early closure charges | Only if you prepay, and only if they apply | Sanction letter, loan agreement |
The first four are known on the day you sign. The last two depend on what happens later, so they do not belong in your comparison sum, but you should still read them.
A worked illustration
Suppose you are offered ₹2,00,000 for three years at 14% a year on a reducing balance. The figures below are for illustration only, not a real offer.
- EMI: about ₹6,836
- Total of 36 EMIs: about ₹2,46,079
- Interest: about ₹46,079
Now add the upfront deductions, assuming a 2% processing fee and ₹3,000 of insurance you agreed to:
- Processing fee: ₹4,000
- GST at 18% on the fee: ₹720
- Insurance: ₹3,000
- Amount reaching your account: ₹1,92,280
So you receive ₹1,92,280 and repay about ₹2,46,079. Your total cost of borrowing is about ₹53,799, not ₹46,079. Measured against the money you actually received, the annual cost works out to roughly 16.8%, not 14%.
That gap is why the APR matters. We explain how it is calculated in our guide to processing fees and APR. Also check whether a quoted rate is flat or reducing, because the difference is large: see flat vs reducing interest rates.
The document that shows all of this
RBI rules require lenders to give you a Key Facts Statement (KFS) before you sign a retail term loan. As of November 2026, it should be in a language you understand, and it should include the APR calculation and a repayment schedule.
For loans of seven days or longer, the KFS terms must stay valid for at least three working days. Use that time. You don’t have to decide while an agent is waiting on the phone.
Read it with a pen and find these answers:
- How much money will actually reach your bank account?
- What is the total repaid by the last EMI?
- Is the insurance optional, and what happens if you decline it?
- What exactly is charged if an EMI bounces or is late?
- Is the rate fixed or floating, and can you close the loan early without a charge?
If the agent’s verbal promise differs from the KFS, trust the KFS and ask for any correction in writing.
The costs that arrive later
Missed payments. Suppose a bounced EMI attracts a ₹500 charge plus 18% GST. That is ₹590 for one slip, and a missed instalment is often more expensive than that, because interest keeps running and the late payment may be reported to the credit bureaus. A lower credit score can make your next loan dearer or harder to get. RBI’s 2023 rules say penal charges should not themselves earn further interest, but they still cost you money.
Closing early. Paying off a loan ahead of time usually saves interest, though a fixed-rate loan may carry a charge. Our guide to prepayment and foreclosure sets out the rules as of November 2026.
Longer tenors. A longer tenor lowers the EMI and raises the total interest. A comfortable EMI is not the same as a cheap loan. Always look at the total repayable as well.
Before you borrow at all
A personal loan is usually unsecured, which means no collateral, but also that the lender is pricing in more risk. A few honest checks:
- Could you wait or save? Interest on a holiday or a gadget keeps running long after the purchase is over.
- Can you afford the EMI in a bad month? Test it against a month with a medical bill or a salary delay, not an average month.
- Are you borrowing to repay another loan? This can make sense only if the new loan is truly cheaper after all fees and you stop adding to the old debt. Otherwise it can become a cycle that is hard to leave. If you are struggling, talk to your existing lender before you miss a payment.
- Is the offer real? An unsolicited offer through a link or an app needs checking first. Our guide on how to spot fake loan apps walks you through it.
If something goes wrong, for example a fee you never agreed to, complain to the lender’s grievance officer first. If it does not reply within 30 days or you are unhappy with the reply, you may escalate to the Reserve Bank - Integrated Ombudsman Scheme through cms.rbi.org.in, if the lender is covered. Check the current terms with the lender, as rules and charges change.
Bottom line
Don’t ask only what the rate is. Ask how much reaches your account, how much you will repay in total, and what the APR is. Then ask whether you need the loan at all. If the numbers still work in a bad month, you are borrowing with your eyes open.
Frequently asked questions
Is the EMI the total cost of a personal loan?
No. The EMI covers principal and interest. Fees deducted at the start, GST on those fees, any insurance you agree to, and later charges for late payment or closing early can all add to what the loan costs you.
Which single number should I compare between two loan offers?
Compare the Annual Percentage Rate (APR) in the Key Facts Statement, and check it against the total amount you will repay. RBI rules require lenders to give a Key Facts Statement for retail term loans, and the APR in it includes the interest rate and other charges.
Can a lender add a charge later that was not in the Key Facts Statement?
As of November 2026, RBI rules say a lender cannot charge a fee that is not mentioned in the Key Facts Statement without your explicit consent. If you find one, ask the lender in writing to explain it, then use its grievance process.
Should I take a personal loan to clear my credit card bill or another loan?
Be very careful. It may lower your interest rate if the new loan is genuinely cheaper and you stop using the card, but borrowing to repay other loans can also start a debt cycle. Add up the full cost first, and if you are already missing payments, speak to your existing lender early.
