A Bengaluru couple with a 50 lakh home loan received a 5 lakh bonus in early 2026 and hesitated between parking it in a mutual fund and throwing it at the loan. Put toward the loan a year in, that single lump sum would knock roughly four years off their tenure and save close to 16 lakh in interest. Understanding why one part-payment can do that, and when it is the right move, is one of the highest value pieces of financial literacy a home buyer can have.

The short answer. Part-payment means paying a lump sum toward your outstanding principal while continuing the loan, and prepayment or foreclosure means closing the loan entirely ahead of schedule. Both cut your interest because interest is charged on the outstanding balance, and both are now free of penalty on floating rate home loans. Under the RBI Pre-payment Charges on Loans Directions, which apply to loans sanctioned or renewed on or after 1 January 2026, regulated lenders cannot levy prepayment or foreclosure charges on floating rate loans taken by individuals for non-business purposes. The trade-off is not the fee, which is gone, but the opportunity cost. Money used to prepay is money not invested elsewhere, so the right call depends on your loan rate versus your alternative returns and your need for liquidity.

This is a buyer-side playbook for Bengaluru borrowers. It explains the difference between part-payment and prepayment, the math that makes early lump sums so powerful, the new no penalty rule, and the honest case for and against paying down early.

What is the difference between part-payment and prepayment?

Part-payment, sometimes called part-prepayment, is when you pay a lump sum toward the principal but keep the loan running. It reduces your outstanding balance, and you then choose whether to keep your EMI the same and shorten the tenure, or keep the tenure and lower the EMI. Prepayment or foreclosure is when you close the entire loan early by paying off the full outstanding amount in one go. Both attack the same thing, the principal on which interest is charged, but they suit different situations. Part-payment fits a borrower with periodic surpluses like bonuses, while foreclosure fits one who has accumulated enough to clear the loan outright.

The key mechanic to internalise is that interest accrues on the outstanding balance every month, so reducing that balance earlier in the loan, when it is largest, removes the most future interest. Timing matters as much as amount.

Why does an early part-payment save so much?

Because of how amortisation works. In the early years of a home loan, most of your EMI goes toward interest and only a little toward principal, so the balance falls slowly and interest keeps piling on a large number. A lump sum in those early years cuts straight into that large balance and erases years of future interest. The same lump sum in the final years saves comparatively little, because the balance is already small.

The 50 lakh example makes this concrete. On a 50 lakh loan at about 8.5 percent over 20 years, the EMI is roughly 43,400 rupees. A 5 lakh part-payment made after the first year, with the EMI kept unchanged, shortens the remaining tenure by close to four years and saves on the order of 16 lakh in interest across the life of the loan. That is a return on your 5 lakh that few safe investments can match, which is exactly why early part-payment is so powerful.

Do prepayment charges still apply in 2026?

For floating rate home loans to individuals, no. Under the RBI Pre-payment Charges on Loans Directions, which apply to loans sanctioned or renewed on or after 1 January 2026, regulated lenders are barred from levying any prepayment or foreclosure charge on floating rate loans taken by individuals for purposes other than business, and this holds regardless of the loan amount, the source of the repayment funds, or whether there is a co borrower. The rule expressly covers part-payments too. The RBI introduced these directions to stop inconsistent charges that had discouraged borrowers from foreclosing or refinancing.

The practical effect for a Bengaluru borrower is that the old excuse for not prepaying, a stiff penalty, is gone for floating rate home loans. That removes a real barrier, but it does not by itself make prepayment the right choice in every case, because the opportunity cost of the money remains.

Should you prepay or invest the surplus?

This is the real decision now that fees are off the table, and it comes down to a comparison of returns and a judgement about liquidity.

1. Compare your loan rate with the after tax return you could reliably earn elsewhere.
2. If your loan rate is higher than your safe return, prepaying usually wins.
3. If you can consistently earn more than your loan rate, investing may build more wealth.
4. Keep an emergency fund intact before prepaying, since prepaid money is hard to pull back.
5. Prefer cutting tenure over cutting EMI when you want maximum interest saving.
6. Prepay earlier rather than later, since early lump sums save far more interest.
7. Factor in any tax deduction you claim on interest before deciding to clear the loan.

Because prepaying principal interacts with the deductions you claim, read our guide to home loan tax benefits under Section 24B and 80C before you decide to clear a loan that is also saving you tax. And since your rate type shapes whether these no penalty rules apply, see our comparison of fixed versus floating home loan rates. When you plan the loan against a specific home, such as Birla Ojasvi, model a couple of part-payment scenarios up front.

Tenure reduction or EMI reduction, which should you pick?

When you make a part-payment, most lenders let you choose whether to keep the EMI and shorten the tenure, or keep the tenure and reduce the EMI. For pure interest saving, cutting the tenure wins, because you keep paying the same amount while the loan closes years earlier, removing a large chunk of interest. Cutting the EMI saves less interest but frees up monthly cash, which is the right choice if your budget is tight or your income is uncertain. There is no universally correct answer, only the one that fits your situation. A comfortable earner chasing an early payoff should shorten the tenure, while a stretched household that needs breathing room should lower the EMI.

What is the honest case against prepaying?

Prepaying is not always the smart move, and it is worth being honest about that. Money you put into the loan is gone from your hands, so aggressive prepayment can leave you cash poor and unable to handle an emergency without fresh, costlier borrowing. If your home loan rate is modest and you can earn more elsewhere after tax, investing the surplus can build more wealth than the interest you would save. And if the interest deduction you claim materially cuts your tax, clearing the loan early forfeits that benefit. The disciplined approach is to keep a solid emergency fund, prepay surpluses you genuinely do not need for liquidity, and prefer early tenure cutting part-payments over a rushed full foreclosure that drains your reserves.

When is the best time to make a part-payment?

Timing changes the payoff dramatically, so it is worth planning rather than paying whenever cash happens to arrive. The single most valuable rule is to prepay as early in the loan as you can, because that is when your outstanding balance is largest and the interest you erase is greatest. A lump sum in year two does far more work than the same amount in year twelve. Within a year, aim to part-pay when you have a genuine surplus that you will not need for near term goals, typically after an annual bonus or the sale of another asset, and only once your emergency fund is intact. It also helps to make part-payments in the same window each year so the habit compounds. A borrower who routes even a modest annual surplus into the loan for the first few years can shorten a 20 year loan into something much shorter, without ever straining a single month's budget. That combination, early and regular, is what turns ordinary savings into extraordinary interest savings.

Are there prepayment charges on a Bengaluru home loan in 2026?

Not on floating rate home loans to individuals. Under the RBI Pre-payment Charges on Loans Directions, applying to loans sanctioned or renewed on or after 1 January 2026, lenders cannot levy prepayment or foreclosure charges on floating rate loans taken by individuals for non-business purposes, and this covers part-payments too, regardless of the loan amount or source of funds.

Is part-payment or full prepayment better?

It depends on your surplus. Part-payment suits periodic amounts like a bonus and lets the loan continue, while full foreclosure suits a large surplus and a goal of being debt free. Both cut interest by reducing the principal. Making the payment early in the loan, when the balance is largest, saves the most interest either way.

Should I reduce my tenure or my EMI when I part-pay?

For maximum interest saving, keep the EMI the same and reduce the tenure, since you keep paying the same amount while the loan ends years earlier. Reduce the EMI instead if your monthly budget is tight and you value lower outgo over the largest possible interest saving. The choice depends on your cashflow, not a single rule.

Should I prepay my home loan or invest the money?

Compare your loan rate with the after tax return you could reliably earn elsewhere. If the loan rate is higher, prepaying usually wins. If you can consistently earn more, investing may build more wealth. Either way, keep an emergency fund intact first, and account for any tax deduction the loan interest gives you.
