What ₹2 lakh prepaid in year 2 saves on a ₹10 lakh personal loan
A ₹10 lakh personal loan at 13.5% over 5 years runs an EMI of ₹23,010 and ₹3.81 lakh of interest if you simply let it run. Pay an extra ₹2 lakh at the end of year 2 and keep the EMI where it is, and you save ₹80,772 — the loan closes 12 months early. Every rupee you prepaid came back as 0.4 rupees of interest you never had to pay.

The same ₹2 lakh prepaid at different points
| Prepaid at | Interest saved | Tenure cut by | |
|---|---|---|---|
| Year 1 | ₹1.18L | 13 months | |
| Year 3 | ₹47,530 | 10 months |
Timing is the whole game. The earlier the lump lands, the more future interest it deletes.
Two ways to take the benefit
| Route | EMI after | Loan ends | What you gain |
|---|---|---|---|
| Reduce the tenure | ₹23,010 | 12 months early | ₹80,772 of interest saved |
| Reduce the EMI | ₹16,223 | On the original date | ₹6,787 a month back in cashflow |
Cutting the tenure saves more money. Cutting the EMI buys breathing room now. Neither is wrong — they answer different questions.
Why year 2 matters more than the amount
Prepayment does not just reduce your balance — it deletes every future interest charge that balance would have generated. In year 2 of a 5-year loan the remaining balance is still about ₹6.78L, so the interest riding on it is enormous. The same ₹2 lakh paid in the final years would save a fraction of this, because there is barely any interest left to cancel.
Prepay or invest?
Prepaying a personal loan at 13.5% is a guaranteed, tax-free return of 13.5% — you cannot lose it in a bad market. An equity fund might beat that over ten years, and might not over three. The honest rule: clear anything above roughly 10% before investing, and treat a cheap home loan as a genuine toss-up that depends on how much certainty you want.
Check the fine print first
On floating-rate loans to individuals, the RBI bars lenders from charging a foreclosure or prepayment penalty — but fixed-rate loans and loans to a business can still carry one. Some lenders also cap the number of part-payments a year or the amount per payment. A quick call before you transfer the money is worth it.

How much does prepaying ₹2 lakh save?
About ₹80,772 in interest, and it ends the loan 12 months early, if you keep paying the same EMI of ₹23,010.
Should I reduce the EMI or the tenure?
Reducing the tenure saves ₹80,772. Reducing the EMI frees up ₹6,787 a month instead but saves far less overall. Choose the tenure cut unless your monthly cashflow is genuinely tight.
Is there a penalty for prepaying?
Not on floating-rate loans taken by an individual — the RBI does not allow lenders to charge one. Fixed-rate loans may carry a charge, so check your sanction letter.
Is prepaying better than investing the money?
Prepaying earns a certain 13.5%, tax-free. Investing might earn more but might not. At 13.5% the maths is clear — clear the debt first.
