Use Bonus to Prepay Personal Loan: A Worked Example

By BillCut
Last updated: 5 November 2026

Many people ask whether they should use bonus to prepay personal loan dues. A part payment cuts the balance on which interest is charged, so it usually lowers the total interest. Whether it is right for you depends on the loan terms, your emergency savings and your other debts. This post walks through an illustrative example with real arithmetic.

How does a part prepayment work?

Your EMI is split between interest and principal. When you pay a lump sum towards principal, the outstanding balance falls. Interest in later months is then charged on a smaller amount. You usually choose between two outcomes: keep the EMI and finish sooner, or keep the tenure and pay a smaller EMI.

RBI’s directions on floating rate EMI personal loans say borrowers can prepay in part or in full at any time, with foreclosure or prepayment charges subject to existing rules. You can read them in the RBI directions on reset of floating interest rate. They also ask lenders to send a quarterly statement showing the principal and interest recovered, the EMI and the EMIs remaining.

Are there charges for prepaying?

This is the first thing to check. RBI’s Pre-payment Charges on Loans Directions, 2025 took effect on 1 January 2026. As summarised by RBI, they stop regulated entities from levying pre-payment charges on floating rate loans to individuals for non-business purposes, with some conditions. The summary does not give rules for fixed rate loans, and many personal loans are fixed rate, so read your own agreement. Pre-payment terms must be stated in the sanction letter, the loan agreement and, where applicable, the Key Facts Statement, and charges not disclosed upfront cannot be imposed later. See the RBI review of the pre-payment directions. Our guide on avoiding foreclosure penalties covers this in more detail.

What does a worked example look like?

This example is illustrative and does not reflect any BillCut offer. Assume a personal loan of Rs 5,00,000 at 14 percent a year for 36 months. The EMI is about Rs 17,089. Over the full term, interest would be about Rs 1,15,197.

After 12 EMIs, the outstanding balance is about Rs 3,55,921. You receive a bonus and prepay Rs 1,00,000, which leaves about Rs 2,55,921.

Path	Remaining months	EMI	Total paid from now, including the Rs 1,00,000
No prepayment	24	Rs 17,089	About Rs 4,10,132
Prepay, keep EMI	17	Rs 17,089	About Rs 3,82,942
Prepay, keep tenure	24	About Rs 12,288	About Rs 3,94,901

Keeping the EMI saves about Rs 27,190 in interest. Keeping the tenure saves about Rs 15,231 but frees up about Rs 4,800 each month. The first path costs less overall. The second path eases your monthly budget. Neither figure includes any prepayment fee, so subtract that if your loan has one. The EMI calculators guide shows how to run your own numbers.

When may prepaying not be the right move?

• You have no emergency fund. Keep a cushion before you part with a lump sum.
• You carry credit card dues at a higher rate. Clear the costliest debt first.
• The loan has a prepayment charge that wipes out the saving.
• You may need the cash soon for a planned expense.

Compare the loan rate with every other debt you hold. The highest rate is the first target. See why a longer tenure for a lower EMI can cost more for the other side of this trade off.

What is a simple step by step plan?

1. Ask the lender for a foreclosure or part payment statement and note any charge.
2. Check whether your loan is fixed or floating.
3. Decide between a lower EMI and a shorter tenure, and ask the lender to apply your choice in writing.
4. Pay through the lender’s official channel and keep the receipt.
5. Check the next statement to confirm the balance has fallen. Later, look at your credit report. RBI’s credit information direction gives you one free full report each calendar year.

If the lender does not respond or applies an undisclosed charge, complain to it first. The RBI Integrated Ombudsman FAQ says you can approach the Ombudsman if there is no reply within 30 days or you are unhappy with the reply, within 90 days after that. See the RBI Integrated Ombudsman FAQs.
