What this free online India home loan refinance calculator does
Home loans in India are long, large and often floating, so a small difference in the interest rate becomes a large sum of money over time. Many borrowers pay a higher rate than a new customer would be offered. A home loan balance transfer, which moves your outstanding principal to a lender with a lower rate, can cut the cost, but it also has a processing fee, GST and other charges. This free online home loan refinance calculator for India shows whether the saving is worth the cost.
Enter your outstanding principal, your current rate and the years left, then the new rate, the processing fee and other charges. The calculator shows the new EMI, the monthly saving, the break-even month, the total interest saved and the effect of keeping your current EMI so that the loan ends sooner. Amounts are in rupees and shown in the Indian number system. Everything runs in your browser, so your figures stay private.
How to use the home loan refinance calculator
- Enter your current loan. Use the outstanding principal, the interest rate and the years left, from your latest statement.
- Add any prepayment charge. For many floating-rate loans to individuals this is zero. Enter the percentage if your loan has one.
- Enter the new loan. Add the new rate, the tenure, the processing fee percentage and GST.
- Add other charges. Include legal, technical, stamp and document charges as a single amount.
- Read the results. Check the break-even and the interest saved, and try keeping your current EMI to see the tenure you could cut.
The costs of a balance transfer
| Cost | Typical form |
|---|---|
| Processing fee | A percentage of the loan, often with a minimum and maximum |
| GST | Charged on the fee at the rate in force |
| Legal and technical | Valuation and title checks |
| Stamp duty and documents | Charges for mortgage documents |
| Prepayment charge | Often nil on floating-rate loans to individuals |
These costs are small against a large loan but not trivial. On a 40 lakh loan, a 0.5% fee with GST is about 23,600, and other charges can add 15,000 or more. The calculator treats them as one cost and finds the month when the saving repays them.
Worked example
A borrower owes 40 lakh at 9.25% with 15 years left, which gives an EMI of about 41,170. A new lender offers 8.5% over 15 years with a 0.5% processing fee plus 18% GST and 15,000 of other charges. The new EMI is about 39,390, a saving of about 1,780 a month. The cost of the transfer is about 38,600, so the break-even is about 22 months. Over an eight-year stay the borrower saves a considerable sum after costs. If the borrower keeps paying the old EMI, the loan ends more than a year earlier. Change the rate gap and the picture changes: at a gap of 0.25 points the break-even stretches to several years.
Alternatives to a balance transfer
- Ask for a rate reduction. Your lender may lower your rate, sometimes for a small fee.
- Switch to a different benchmark. Some floating-rate loans can be moved to a newer benchmark-linked rate.
- Prepay. Extra payments reduce the principal and the interest.
- Part-prepay and keep the EMI. This shortens the tenure.
How the EMI and the tenure work
Your EMI, or equated monthly instalment, is fixed for a given balance, rate and tenure, but its make-up changes over time. In the early years most of the EMI is interest, and the share that repays principal grows slowly. Because the interest is front-loaded, a balance transfer saves the most early in the loan. After many years, little interest remains to save and the fee may not be worth paying.
On a floating-rate loan, the lender may keep your EMI the same and change the tenure when the rate moves, or change the EMI. Check what your loan does, because it changes how a transfer compares. The calculator assumes a fixed rate for the rest of the tenure for both loans, which keeps the comparison simple and fair. If your rate is linked to a benchmark, it can move after the transfer, so test a range of new rates in the rate table.
Finally, decide what you want from the saving. A lower EMI eases your monthly budget. Keeping your current EMI on the new, lower rate pays the loan off sooner and saves more interest in total. The calculator lets you see both, so you can choose the one that matches your plans.
Common mistakes
- Looking at the rate alone. Fees and GST count.
- Forgetting the effect on tenure. A longer tenure lowers the EMI but raises interest.
- Transferring late in the loan. Most of the interest is paid early, so there is less to save.
- Ignoring floating-rate changes. The new rate can also change.
- Using example figures.

Frequently asked questions
What is a home loan balance transfer?
It is moving the outstanding principal of your home loan from your current bank or housing finance company to another lender that offers a lower interest rate. The new lender pays off the old loan, and you repay the new lender.
Is it worth transferring my home loan?
It usually pays when the rate gap is meaningful, you have many years left, and the processing fee and other charges are small compared with the interest you save. The break-even month tells you when the savings repay the cost.
How much rate difference makes a balance transfer worthwhile?
There is no fixed rule, but a gap of around half a percentage point or more on a large balance with a long tenure is often cited as worth examining. Enter your own numbers to see the break-even.
What fees does a balance transfer involve?
Typically a processing fee, which is a percentage of the loan with GST added, plus legal, technical valuation, stamp and document charges. Some lenders waive or reduce the fee as an offer.
Is there a prepayment penalty on my current loan?
For floating-rate home loans to individuals, the Reserve Bank of India has directed lenders not to charge prepayment or foreclosure penalties, and recent directions have widened this. Fixed-rate loans or loans to other borrowers may differ. Check your sanction letter and the current rules.
How is GST applied to the processing fee?
GST is generally charged on the processing and other service fees, at the rate in force, which is 18% at the time of writing for such services. Enter the rate shown on your quote.
Will my EMI go down or will my tenure go down?
You can choose. Taking the new EMI lowers your payment. Keeping your current EMI on the lower rate shortens the tenure and saves more interest overall. The calculator shows both.
Can I ask my existing bank to cut my rate first?
Yes. Many lenders offer a rate reduction or a conversion to a lower floating rate for a small fee. This can be cheaper than a transfer, so ask before you move.
Can I get a top-up loan with the transfer?
Some lenders offer a top-up on a balance transfer. This calculator compares the same outstanding principal. A top-up is extra borrowing and should be compared separately.
Does a transfer affect my credit score?
A new application involves a credit check, and a record of the new loan will appear in your credit history. Ask your lender about the effect on your score.
What about tax benefits?
Deductions for home loan interest and principal depend on the tax regime you choose and the rules in force. A balance transfer does not usually remove them, but check with a tax adviser. The tool ignores tax.
Should I roll the charges into the loan?
Some lenders allow it. It avoids a cash payment but increases the loan, so you pay interest on the charges. Choose that option in the calculator to see the effect.
What happens to my property documents during the transfer?
The new lender takes the property documents from the old lender once it pays off the loan. Follow the process the lender describes, and keep records of the closure.
Can I use the tool for a loan against property?
It works for any amortising loan with a fixed tenure. Rates and charges differ for a loan against property, so enter your own.
How accurate are the default figures?
They are examples only. Replace every field with the figures in your loan statement and the new lender's offer.
Is my information private?
Yes. The calculator runs in your browser. Nothing you enter is sent to a server, saved or shared, and reloading the page resets it.
Is this India home loan refinance calculator free?
Yes. It is a free online calculator with no sign-up, trial or limit. You can print or download the results.
