A raise comes through, or a bonus lands, and the question that follows for most home loan borrowers is the same: put it toward the loan as a lump sum, or use it to permanently raise the monthly instalment. Both routes reduce what you eventually pay in interest, but they work differently, and picking the wrong one for your situation can leave you either short on liquidity or paying less than you comfortably could.
Individual borrowers with a floating-rate Bajaj Finance Home Loan can part-prepay or foreclose the loan without an additional charge, which is worth knowing before you weigh a lump sum against a permanent EMI increase.
Should you prepay your home loan or opt for a higher EMI?
It depends on whether the money you’re putting toward the loan is a one-time amount or a lasting increase in your income. A bonus, a maturing investment, or an inheritance is a one-time event, and a candidate for a lump sum prepayment. A confirmed salary hike or a new source of steady income is recurring, and better suited to a permanent EMI increase, since it doesn’t require you to hand over a large sum all at once.
How does a lump sum prepayment actually reduce your loan cost?
A prepayment reduces your outstanding principal directly. You can typically choose whether the lender applies it to shorten your tenure or lower your EMI going forward, while keeping the other constant. Shortening the tenure while keeping the EMI unchanged saves more in total interest, because the loan is repaid faster and less interest accrues over time.
Using a home loan calculator with prepayment shows you the impact of a lump sum on your monthly EMI. Add your outstanding balance, interest rate, remaining tenure, and the prepayment amount to see your revised EMI. You can then choose to pay the revised EMI for the remaining tenure, or pay your current EMI for a shorter tenure and save on total interest.
How does increasing your EMI achieve a similar result gradually?
Raising your EMI means you commit to a higher fixed monthly outflow for the rest of the loan, without a large upfront amount. Each higher instalment chips away at the principal faster than your original EMI would have, so you finish repaying sooner and pay less total interest. This is similar in effect to a tenure-reduction prepayment, but spread gradually instead of applied all at once.
Lump sum prepayment vs higher EMI: which trade-offs matter most?
| Factor | Lump sum prepayment | Increased EMI |
| Source of funds | One-time amount (bonus, maturity proceeds) | Recurring income increase |
| Impact on liquidity | Reduces available cash immediately | Reduces monthly disposable income going forward |
| Flexibility | One-time decision, doesn’t recur automatically | Ongoing commitment across the remaining tenure |
| Best suited for | Windfalls you don’t need to hold as reserves | A confirmed, sustainable rise in income |
| Charge for individual floating-rate borrowers | No additional charge | Not applicable — EMI increases don’t carry a separate charge |
What should you verify before choosing either option?
Before committing to a lump sum prepayment, confirm your emergency fund is intact and that you don’t have costlier debt, such as a credit card balance, that should be cleared first. Before committing to a higher EMI, be reasonably certain the income increase behind it is sustainable, not a one-off bonus mistaken for a raise. An EMI increase that later strains your budget is harder to reverse than deciding not to prepay a lump sum.
Does the timing of your loan change which option works better?
Yes. Earlier in a loan’s tenure, a larger portion of each EMI goes toward interest, so both prepayment and EMI increases have a bigger effect on total interest saved. Later in the tenure, when principal is already substantially repaid, the interest-saving benefit of either approach is smaller relative to the amount involved. If you’re early in your loan and can sustain a higher EMI, that route compounds its benefit over more remaining years than the same decision made a decade in.
How do rate type and tenure affect the decision?
The Bajaj Finance Home Loan carries interest rates starting from 7.25%* p.a. for salaried applicants and 7.70%* p.a. for self-employed applicants, with a repayment tenure of up to 32 years*, based on eligibility. Floating rates linked to an external benchmark, such as the repo rate, are available, alongside fixed-rate options. If you’re on a floating rate and the benchmark moves down, an EMI that already went up due to your own choice earlier can end up being managed more comfortably; if you’re on a fixed rate, your instalment stays predictable regardless of what the benchmark does, which changes how confident you’d need to be before committing to a higher fixed monthly amount.
Can you combine both approaches?
There’s no rule against doing some of each: using part of a windfall for a lump sum prepayment while also increasing your EMI modestly if your income has genuinely grown. In practice, most borrowers pick one primarily because managing two separate changes at once adds complexity without a proportionate benefit, but if you have both a one-time amount and a durable income increase available to you, splitting the benefit between the two isn’t unreasonable. What matters more than which single option you pick is that whichever you choose is sized to something real — an actual windfall amount or an actual, sustained income change — rather than an aspirational figure.
What mistakes do borrowers make with this decision?
A common one is treating a bonus as guaranteed and future bonuses as a source for an ongoing higher EMI, when bonuses by nature vary year to year and aren’t a reliable base for a permanent commitment. Another is prepaying with funds that were actually earmarked for a different near-term goal, only to realise later that they’re needed elsewhere and can’t easily be pulled back out of the loan. A third is increasing the EMI without first confirming the increase alongside other financial commitments that may also grow over time, such as rent if you’re servicing two properties, or school fees that rise annually.
How do you actually request a prepayment or EMI change?
Both prepayment and EMI adjustment are requests you make to your existing lender once the loan is disbursed — they aren’t decisions you can make unilaterally without informing your lender. Keep your KYC documents (identity and address proof) current with your lender, since outdated records are a common reason these requests get delayed. Servicing requests for the Bajaj Finance Home Loan, including prepayment, can be initiated online, without requiring a branch visit.
Making the call: what should guide your final decision?
If the money in question is a one-time amount and your reserves can spare it, a lump sum prepayment applied toward reducing your tenure typically delivers the larger interest saving. If it’s a genuine, ongoing rise in income, a higher EMI achieves a similar effect gradually, without asking you to part with a large sum at once. Either way, the decision is easier to reverse if you start smaller and confirm the impact on your monthly finances before going further.
