Home Loan Prepayment, Foreclosure & Part-Payment Calculator
You have a running loan and some spare money. Should you prepay it, close it entirely, spread it out, or invest it instead? Enter your loan once below โ every calculator on this page works from it and answers one of those questions.
Prepaying a loan is one of the highest-certainty financial moves available to an Indian borrower โ a guaranteed, tax-free return equal to your loan rate. But "should I?" has more than one answer, and the right one depends on where you are in the loan and what else the money could do.
Where You Stand Today
Before deciding what to do with extra cash, see your real position โ how much principal you've actually cleared, how much of what you've paid so far was pure interest, and how much loan is still ahead of you. Every calculator below acts from this outstanding balance, not your original loan amount.
โ You know your balance โ here's what adding a little extra each month does to it.
How Much Can I Save by Prepaying?
Adding a fixed amount to every EMI attacks the principal directly. Because interest is charged only on the outstanding balance, every extra rupee today removes many rupees of interest across the rest of the loan.
โ Have a lump sum instead of a monthly surplus? Then a bigger choice opens up.
Should I Reduce EMI or Loan Tenure?
After a lump-sum part-payment, your lender lets you choose: keep the EMI the same and finish the loan early, or keep the tenure the same and pay less each month. They are not equivalent โ one saves far more interest than the other.
Keep the EMI, cut the tenure. It clears the expensive early-interest years faster.
โ But is one big payment even the best way to deploy that money? Compare structures.
What Is the Best Part-Payment Strategy?
A given amount can be deployed several ways: all at once today, spread as annual payments, or trickled in monthly. This compares three strategies of equal total value so you can see which structure saves the most interest.
โ If the lump sum could clear the loan entirely, should you just close it?
Should I Foreclose My Loan?
Three honest scenarios laid side by side: keep paying as you are, use the lump sum to reduce or close the loan now, or keep the money invested instead. There's no universal winner โ just the consequence of each under your own numbers.
โ That last scenario deserves its own proper look โ prepay versus invest, with tax.
Should I Prepay or Invest the Money?
Prepaying earns a guaranteed, tax-free return equal to your loan rate. Investing might beat that โ but the return is uncertain and usually taxed. This finds the break-even return your investment must reliably clear just to match prepaying.
โ One more thing that changes all of this: your rate isn't fixed forever.
What Happens If Interest Rates Change?
Floating-rate loans move with the RBI's repo rate. When it rises, most banks quietly stretch your tenure instead of raising your EMI โ so the cost hides in years, not rupees, unless you ask otherwise. Prepaying is one way to blunt that.
How Much Does Prepayment Timing Matter?
The single most important thing about prepaying is when you do it. Because interest is charged on the outstanding balance, a prepayment early in the loan removes years of future interest, while the same amount late in the loan removes very little. Here's the same โน5 lakh one-time prepayment on a โน50 lakh, 8.75%, 20-year loan โ made at three different points, keeping the EMI the same and cutting the tenure:
| Prepay โน5L atโฆ | Interest saved | Loan ends sooner by |
|---|---|---|
| Year 3 (early) | โ โน13.9 lakh | โ 3.6 years |
| Year 10 (midway) | โ โน5.9 lakh | โ 2.1 years |
| Year 15 (late) | โ โน2.3 lakh | โ 1.4 years |
The same โน5 lakh works six times harder in year 3 than in year 15. This is the core logic behind prepaying: the earlier the rupee lands on the principal, the more interest it erases. Use the calculators above with your actual EMIs-paid figure to see your own numbers โ and if you have a choice, prepay sooner rather than saving up for a bigger payment later.
Balance Transfer vs Prepayment
Prepaying attacks the principal; a balance transfer attacks the rate โ moving your outstanding loan to a lender offering a lower one. When your rate is well above what's currently available, switching can save more than a modest prepayment, because it lowers every remaining EMI rather than shortening the loan once.
๐ฐ Prepay whenโฆ
- Your rate is already competitive
- You have surplus cash and want a guaranteed, tax-free return equal to your rate
- You're early in the loan, where principal reduction bites hardest
- You want to be debt-free faster without ongoing paperwork
๐ Transfer whenโฆ
- Another lender's rate is materially lower โ roughly 0.5% or more
- Significant tenure remains for the lower rate to compound
- The new lender's processing fee is small next to the interest saved
- You don't have a lump sum to prepay but want to cut cost
After You Close the Loan: Documents & NOC
Closing a loan isn't done when the last rupee is paid โ it's done when the paperwork is clean. Run through this checklist so the closure is properly recorded and your property and credit file are clear:
- Get the No-Dues Certificate (NOC). This is the lender's written confirmation that nothing remains outstanding โ your single most important proof of closure.
- Collect your original property documents. The lender must return them within 30 days of full repayment, with compensation of โน5,000 per day of delay under RBI rules. Check every page is present before you leave.
- Ensure the lien / charge is removed. For a home loan, confirm the bank files to remove its charge with the sub-registrar (and updates the CERSAI record), so the title is unencumbered.
- Reclaim security cheques & cancel the ECS mandate. Collect any post-dated or security cheques and stop the auto-debit so no stray EMI is pulled.
- Check your credit report in 30โ45 days. The loan should show as "closed" on CIBIL. A loan left showing "active" can hurt future eligibility โ raise it with the lender if it hasn't updated.
What to Do With a Year-End Bonus
Say you're three years into a โน40 lakh, 8.75%, 20-year home loan โ an EMI of about โน35,350 โ and a โน3 lakh bonus lands. You have three honest choices, and the calculators above quantify each on your real balance:
- Prepay it against the loan. At year 3, โน3 lakh knocked off the principal (keeping the EMI, cutting the tenure) removes well over โน7 lakh of future interest and shortens the loan by roughly two years โ a guaranteed, tax-free return equal to your 8.75% rate.
- Invest it instead. At a 12% expected return the โน3 lakh could grow larger over the same horizon โ but that return is uncertain and, for equity, taxed, while the prepayment's return is locked in. The prepay-vs-invest section above finds the exact break-even.
- Keep it as an emergency buffer. If you don't already hold 6 months of expenses in reserve, that comes first. Prepaying is irreversible โ money that's gone into the loan can't be pulled back out in a crisis.
Prepayment and Your Tax Benefit
There's one wrinkle worth understanding before you prepay a home loan under the old tax regime. The interest you pay is partly deductible โ up to โน2 lakh a year under Section 24(b) โ so a rupee of interest doesn't cost you a full rupee. For someone in the 30% slab claiming the full deduction, the effective interest rate on the loan is lower than the headline rate, because the taxman is subsidising part of it.
When you prepay, you lose some of that interest โ and therefore some of that deduction. It doesn't make prepaying a bad idea; prepaying still saves real money. But it slightly narrows prepayment's edge over investing, because the loan you're clearing was a little cheaper, after tax, than its sticker rate suggested.
Common Prepayment Mistakes
Prepaying is almost always smart โ but a few avoidable errors blunt the benefit:
- Emptying your emergency fund to prepay. Prepaid money is locked in the loan. Keep 6 months of expenses liquid before you touch the principal.
- Breaking a higher-returning investment to prepay a cheap loan. If an investment reliably out-earns your post-tax loan rate, redirecting it to prepayment can cost you โ run the break-even first.
- Choosing "reduce EMI" when you meant to save interest. After a part-payment, cutting the tenure (keeping the EMI) saves far more than cutting the EMI. Only pick the lower EMI if you specifically need the monthly relief.
- Prepaying a fixed-rate loan without checking the charge. The RBI no-penalty rule covers floating individual loans; a fixed-rate loan may still levy a foreclosure charge, which can eat into the saving.
- Forgetting the paperwork. After a full closure, chase the NOC, your original documents and the credit-bureau update โ an unclosed record on CIBIL can quietly hurt your next loan.
