1. The break-even calculation
The formula is simple:
Break-even months = Total upfront costs ÷ Monthly EMI savings
For example: if you pay ₹45,000 in closing costs and save ₹3,500/month, your
break-even is about 13 months. If you plan to keep the loan for at least 13 more
months, refinancing saves you money.
2. What counts as closing costs
- Processing fee: 0.5–2% of the new loan amount
- Legal & documentation: ₹5,000–25,000
- Valuation fee: ₹2,000–10,000 (for secured loans)
- Stamp duty: varies by state; can be significant
- Prepayment penalty on old loan: 0–4% of outstanding balance
- New insurance / registration: if required
⚠️ Stamp duty on a new loan can add 0.1–0.5% of the loan amount — often the largest single closing cost. Always confirm the exact amount with your lender before proceeding.
3. Lower rate vs. shorter tenure
You can refinance for either — or both:
- Lower rate, same tenure: reduces your EMI and total interest. The simplest win.
- Lower rate, shorter tenure: keeps your EMI roughly the same but dramatically reduces total interest. Best for maximizing savings.
- Lower rate, longer tenure: lowers your EMI but may not reduce total interest. Watch this carefully — the lower EMI can be deceptive.
4. When refinancing doesn't make sense
- Rate difference is small. If you're saving less than 0.5%, closing costs may eat the benefit.
- You plan to move or sell soon. If you'll repay the loan within the break-even period, you'll lose money.
- Your credit has worsened. You might not qualify for a lower rate.
- Prepayment penalty is high. A 3–4% penalty can wipe out years of savings.
- You're extending the tenure significantly. A lower EMI with a much longer tenure often costs more overall.
5. Refinancing a home loan
Home loan refinancing (balance transfer) is common in India. Floating-rate home
loans usually have no prepayment penalty, making it easier to switch. The main
considerations are:
- New lender's rate and reset frequency
- Processing fees and legal charges
- Whether the new lender offers better service
- Time and effort involved in switching
6. Refinancing a personal, car, or business loan
These are also refinanceable, but:
- Personal loans: often unsecured, so prepayment penalties are common. Check first.
- Car loans: secured; refinancing usually involves a balance transfer to another lender.
- Business loans: refinancing can significantly reduce cost if your business has grown and qualifies for a lower rate now.
7. Common mistakes to avoid
- Focusing on EMI alone. A lower EMI with a longer tenure can cost more overall.
- Forgetting closing costs. They can be 1–3% of the loan amount.
- Ignoring the prepayment penalty. It's often the biggest single cost.
- Refinancing too often. Each refinance resets your loan clock and adds costs.
- Not negotiating. Lenders will often match a competing offer if you ask.
8. How to use this calculator
- Enter your current loan's outstanding balance, rate, and remaining tenure.
- Enter the refinancing offer's rate, tenure, and closing costs.
- Add any prepayment penalty on the old loan.
- See your monthly EMI savings, break-even time, and lifetime savings.
- Check the verdict banner: does refinancing make sense for you?
- Adjust the numbers to test different scenarios.
9. Final thoughts
Refinancing can be one of the most powerful financial moves available — a 2% rate
reduction on a ₹30 lakh loan over 15 years saves over ₹6 lakh in interest. But it
only works if you stay long enough to recover the costs. Run the numbers, negotiate
hard, and make sure the math works for your timeline.
