Personalized next steps
Enable a 5% Step-Up EMI every year
Your income typically rises each year. Increasing your EMI by 5% annually stays affordable while cutting interest significantly.
Increase Monthly EMI by Rs 2,500
Adding Rs 2,500 to your EMI reduces total interest by Rs 7.29 L and closes your loan 3y 10m earlier.
Reduce tenure by 2 years
EMI increases by only Rs 1,129, but you avoid two full years of interest at the tail end of the loan.
Make a Rs 90.0 K prepayment in Year 1
A lump-sum prepayment in the early years hits interest hardest, because your outstanding principal is at its peak. Year 1 gives the biggest saving among the first five years for this loan.
About the Prepayment Calculator
Prepayment is the only lever on an existing loan that works without asking anyone's permission. You cannot change the rate you were sanctioned or the tenure already elapsed, but you can attack the outstanding principal — and because interest is charged on that balance, every rupee you prepay removes all the future interest that rupee would have generated.
The catch is timing. A prepayment in year two is worth many times the same amount in year fifteen, because early in a loan the balance is large and almost the entire EMI is interest. This calculator rebuilds the full amortization both ways so you see the exact months saved and the exact interest removed, rather than a rule of thumb.
Worked example: ₹30 L at 9% for 20 years — before and after
- Baseline EMI
- ₹26,992
- Baseline tenure
- 240 months (20y)
- Baseline interest
- ₹34,78,027
- With ₹5,000/month extra
- 163 months (13y 7m)
- Plus ₹2 L lump sum at month 24
- 147 months (12y 3m)
- Interest saved
- ₹16,06,904
Baseline first: ₹30 L at 9% over 20 years. EMI ₹26,992, total interest ₹34,78,027, loan closes in month 240. That is the 'do nothing' scenario every comparison should start from.
Now add ₹5,000 a month from the first instalment — an 18% increase in outflow. The loan closes in month 163 instead of 240: six years and five months earlier. Total interest falls from ₹34,78,027 to ₹22,02,334, a saving of ₹12,75,693. You spent roughly ₹8.15 L in extra payments to remove ₹12.76 L of interest.
Add one ₹2 L lump sum at month 24 — a bonus, a maturing FD — on top of that monthly top-up, and the loan closes in month 147: twelve years three months, nearly eight years early. Interest drops to ₹18,71,123. Total saving against baseline: ₹16,06,904.
The asymmetry is the point. That same ₹2 L applied at month 180 instead of month 24 would save well under ₹50,000, because by then the remaining balance generates very little interest. Prepayment is a front-loaded strategy — the value decays every year you wait.
How it’s calculated
Each month: interest = balance × r; balance −= (EMI − interest) + extra payment
The calculator runs the amortization month by month rather than using a closed-form shortcut, because lump sums and recurring top-ups change the balance path in ways a formula can't capture. Extra payments are applied directly to principal after that month's interest is charged, and the schedule ends when the balance reaches zero — which is why the output is a real month count, not an estimate.
One structural choice matters when you actually make the prepayment: ask the lender to reduce the tenure, not the EMI. Reducing the tenure keeps your outflow the same and removes the maximum interest. Reducing the EMI feels better monthly and gives back most of the benefit. Banks frequently default to the second option unless you instruct otherwise in writing.
On charges: RBI prohibits prepayment and foreclosure penalties on floating-rate home loans taken by individuals, so for most home borrowers this is free. Fixed-rate loans and most personal loans do carry 2–5% foreclosure charges — check the sanction letter before making a large lump sum.
Factors that affect your prepayment savings
How early you start
The dominant variable. ₹2 L at month 24 saves lakhs; the same ₹2 L at month 180 saves tens of thousands. The interest you can remove only exists while the balance is large.
Tenure reduction vs EMI reduction
Always ask for tenure reduction in writing. EMI reduction returns the monthly comfort but surrenders most of the interest saving.
Interest rate on the loan
Prepayment is a guaranteed, tax-free return equal to your loan rate. At 9% that beats most debt instruments after tax; at 14% on a personal loan it beats almost anything.
Prepayment charges
Zero on individual floating-rate home loans by RBI mandate. Typically 2–5% on fixed-rate and personal loans, which can erase the benefit of a small lump sum.
Section 24(b) tax relief
Home loan interest is deductible up to ₹2 L a year under the old regime. If you are claiming it fully, your effective loan rate is lower — which narrows, but rarely reverses, the case for prepaying.
Emergency fund first
Prepaid money is gone; you cannot withdraw it. Keep six months of expenses liquid before diverting anything to the principal.
Next: decide whether that money should prepay or invest
Prepaying at 9% is a guaranteed 9% tax-free return. An equity SIP might average more over a decade — but 'might' is doing real work in that sentence, and the two options have completely different risk profiles.
The Smart Money Planner runs both paths on your actual numbers: interest saved by prepaying versus projected corpus from investing the same amount, adjusted for your tax slab and the deduction you would lose. It won't tell you what to feel; it will tell you what the numbers say.
Common mistakes
- Letting the bank reduce the EMI instead of the tenure, which gives back most of the saving.
- Waiting for a large round sum instead of starting a small monthly top-up immediately.
- Prepaying a 9% home loan while carrying a 14% personal loan or revolving card debt.
- Emptying the emergency fund into a prepayment and then borrowing at a higher rate three months later.
- Making a big lump sum on a fixed-rate or personal loan without checking the 2–5% foreclosure charge.
- Not getting written confirmation of the revised schedule — always ask for the updated amortization statement.

How does loan prepayment work?
Every rupee you pay above the scheduled EMI is applied entirely to the outstanding principal. Because interest is charged monthly on that balance, cutting the balance early cuts every future interest calculation — which is why small extras in year one save far more than the same amount in year fifteen.
Reduce EMI vs reduce tenure
Indian lenders default to 'reduce tenure' — you keep paying the same EMI, but the loan closes earlier. That saves the most interest. 'Reduce EMI' keeps the tenure the same and drops the monthly outflow — useful only when cash flow tightens. You can usually ask your lender to switch modes any time.
Prepay vs invest
Prepay when the loan rate exceeds your realistic after-tax investment return. On a 9% floating home loan, prepayment is effectively a guaranteed 9% tax-free return — hard for equity SIPs to beat after tax. On a 7% home loan with active 80C/24(b) deductions, disciplined equity investing may edge ahead over 15+ years.
Extra EMI vs lump sum — which lever matters more?
Depends on tenure and amount. On a long home loan (20+ years), a modest recurring extra EMI usually beats a one-off lump sum by year 8–10 because it compounds. On a short personal loan (2–3 years), a well-timed lump sum in month 3–6 wins outright. This calculator ranks all three levers on YOUR numbers so you can see which one to focus on.
What is step-up EMI?
You raise the EMI by a fixed percentage — typically 5% — every 12 months to match salary hikes. On a 20-year home loan at 8.5%, a 5% annual step-up closes the loan roughly 7–8 years earlier and cuts total interest by 30–40%. Shorter loans see smaller but still meaningful savings.

Frequently asked
Almost always, if the loan rate is higher than your realistic after-tax investment return. A 9% floating home loan prepaid early gives you a guaranteed 9% tax-free saving on future interest — very hard to beat. The main exceptions: (a) you have no emergency fund yet, (b) you're already using the full ₹2 L Section 24(b) interest deduction and equity SIPs beat the after-tax rate for you, or (c) the lender charges a foreclosure penalty that eats the saving.
Reduce tenure. Keeping the EMI constant means every extra rupee compounds against a shrinking balance for the full remaining tenure, which saves the most interest. Reduce EMI is a cash-flow tool, not a savings tool — the interest cut is real but roughly 40–60% smaller on identical prepayments.
Depends on the loan type. Floating-rate home loans: zero, by RBI mandate. Fixed-rate home loans: typically 2% on the outstanding. Car and personal loans: usually 2–5% for the first 12–24 months, dropping to nil after. Education loans: most Indian lenders (SBI, PNB, Axis, HDFC Credila) charge nothing. Always read the sanction letter.
Most Indian lenders accept any partial prepayment above ₹5,000–₹10,000, though some limit you to 2–4 prepayments per year. There is no maximum — you can foreclose the entire outstanding at any time. Some banks require a prepayment request 24–48 hours in advance so the amortization is recomputed correctly.
As early as possible. In the first 20% of the tenure, roughly 70–80% of every EMI goes to interest — a rupee prepaid then eliminates far more future interest than the same rupee prepaid in the last 20%. Late-tenure prepayments barely move the needle because you're already paying mostly principal.
Compare the loan rate to your realistic after-tax equity return. Home loan at 8.5% floating with 80C/24(b) benefits fully used → equity SIPs at 12% long-term historical returns may edge ahead. Personal loan at 14% → prepay first, always. Car loan at 9.5% fixed → prepay, because there's no tax benefit. Never SIP with borrowed money at 12%+.
No. Full foreclosure closes the loan account, which briefly reduces your credit mix score by 5–15 points, but the drop is temporary and small. Partial prepayments have no negative impact — some lenders even report them as positive account activity. Never avoid prepaying to 'protect' your credit score.
Yes at almost every major Indian lender — SBI, HDFC, ICICI, Axis, Kotak, Bajaj Finserv all support partial prepayment via their app or netbanking. Full foreclosure still requires a written request in some cases so the NOC and lien-release can be processed.
By default your EMI stays the same and the tenure shrinks. You can request 'reduce EMI' mode instead — the lender recomputes the EMI on the reduced balance for the same remaining tenure. Reducing tenure saves more interest; reducing EMI helps cash flow. You can switch modes on subsequent prepayments.
Neither is strictly better. Step-up is automatic and compounds with your income, which suits salaried borrowers on a predictable hike cycle. Manual lump sums are more flexible and let you time prepayment around bonuses. Combining both — 5% annual step-up plus a lump sum from the yearly bonus — beats either lever alone by a wide margin, which this calculator shows directly.
For partial prepayments via the app or netbanking, no — the system handles it. For large prepayments above ₹10 L or full foreclosure, most lenders require a prepayment / foreclosure request 3–5 working days in advance so the interest calculation and NOC are correct. Always ask for a fresh amortization schedule after every partial prepayment.
