Does Loan Prepayment Reduce EMI or Tenure? Which Option Saves More?
By Pradipta Ray · Published
When you make a lump-sum prepayment against your home loan or personal loan, banks ask you a crucial question: do you want to reduce your monthly EMI or reduce your loan tenure? Here is the mathematical truth.
Making a partial prepayment directly reduces the outstanding principal balance on your loan. Because future interest is computed strictly on the remaining principal, you can either keep your monthly EMI unchanged to end the loan years earlier, or keep the original tenure and enjoy a lower monthly instalment.
Direct Answer: Reducing tenure saves substantially more interest. On a ₹30 Lakh home loan at 8.5% over 20 years, a ₹2 Lakh prepayment in Year 3 saves approximately ₹5.72 Lakh if you reduce tenure (shortening the loan by 32 months), versus only ₹3.14 Lakh if you reduce monthly EMI.
Worked Example: ₹2 Lakh Prepayment on ₹30 Lakh Loan
| Metric | Original Loan | Prepay & Reduce Tenure | Prepay & Reduce EMI |
|---|---|---|---|
| Monthly EMI | ₹26,035 | ₹26,035 | ₹24,115 |
| Loan Tenure Remaining | 204 months | 172 months | 204 months |
| Total Interest Paid | ₹32,48,322 | ₹26,76,140 | ₹29,34,580 |
| Total Interest Saved | ₹0 | ₹5,72,182 | ₹3,13,742 |
| Time Saved | 0 months | 32 months (2.6 yrs) | 0 months |
The Hybrid Prepayment Strategy
If you want the best of both worlds, ask the bank to reduce your EMI to provide breathing room in your monthly budget, but continue manually transferring the difference into a recurring deposit or mutual fund SIP. Alternatively, prepay small sums annually to steadily reduce tenure while keeping your lifestyle untouched.
Checklist for Submitting a Prepayment
Explicitly select 'Tenure Reduction' on your bank's net banking portal or prepayment request form.
Verify that the funds are credited directly against the principal account, not parked in advance EMI buffers.
Download an updated amortization schedule immediately to confirm the revised loan maturity date.
