Is a balance transfer worth it? The break-even math
A balance transfer is not free money. It saves you the interest you would have paid at the old rate, and it costs you a fee to move. It is worth doing when the first number beats the second — and the honest way to know is the break-even point, not the advertised rate.

What a balance transfer actually is
You owe money on a credit card at a high rate. Another lender offers to pay off that card and carry the debt for you at a lower rate. Your balance does not shrink — it moves. What changes is the rate that applies to it from that day forward, and you pay a fee for the move.
The same mechanism applies to loans. A home loan or personal loan can be transferred to a lender offering a lower rate, and the arithmetic below is identical.
When transferring saves money
Three things decide it:
- The size of the rate gap. Moving from 42% to 14% is transformative. Moving from 42% to 38% usually is not.
- How much time is left. Interest accrues over the remaining months. A big rate cut with two months to run saves very little.
- What the switch costs. Typically a processing fee as a percentage of the balance, plus 18% GST on that fee, plus any fixed charges.
The break-even calculation
This is the whole decision in one line:
If your EMI falls by ₹2,139 a month and the switch costs ₹2,655, you are even after two months. Every month after that is real saving. If the break-even lands near the end of your remaining tenure, the transfer largely pays for itself and not much more.
Two rate quotes alone cannot tell you this. You need the balance, the remaining tenure and the fee as well — which is what the calculator asks for.
A worked example
₹1,50,000 sitting on a credit card at 42% p.a., cleared over 24 months, moved to a 14% offer with a 1.5% processing fee plus GST:
| Stay put | Transfer | |
|---|---|---|
| Rate | 42% p.a. | 14% p.a. |
| Monthly EMI | ₹9,341 | ₹7,202 |
| Total interest over 24 months | ₹74,182 | ₹22,846 |
| Cost to switch (1.5% + 18% GST) | — | ₹2,655 |
| Net saving | — | ₹48,681 |
| Break-even | — | 2 months |
The EMI falls ₹2,139 a month and the fee is recovered in the second month. On these inputs the transfer is clearly worth it.
When a transfer is the wrong move
Change two inputs and the same balance tells a different story. ₹1,50,000 at 42% moved to 38% with a 3% fee plus GST:
| Value | |
|---|---|
| EMI reduction | ₹324/month |
| Gross interest saved | ₹7,777 |
| Cost to switch | ₹5,310 |
| Net saving | ₹2,467 |
| Break-even | 17 of 24 months |
₹2,467 over two years, and you carry the balance for seventeen months before you are even. A narrow rate gap and a high fee cancel each other out. That is the case to walk away from.
Other situations where transferring rarely pays:
- You are close to clearing the balance anyway. Little interest remains to be saved, but the full fee still applies.
- A 0% promotional period you will not beat. If the balance is still there when the promotion ends, the rate that follows may be no better than what you left.
- The new EMI does not fit your budget. A lower rate over a shorter tenure can raise the monthly payment. Missing it costs more than the transfer saves.
- You keep spending on the old card. Moving the balance frees up a limit. Filling it again leaves you with two debts instead of one.
How to use the calculator
- Outstanding balance — what you owe today, not the original amount.
- Current rate — the annual rate on that balance. Indian credit cards commonly sit between 36% and 48% p.a.
- Remaining tenure — how long you realistically need to clear it. This drives the result more than most people expect.
- New rate — the rate actually offered to you, not the headline advertised rate.
- Processing fee and GST — the quoted percentage, with the GST toggle on unless the lender has confirmed otherwise.
- Other charges — foreclosure charges on the old account, documentation or legal fees.
The verdict it shows is a comparison of costs on the figures you entered. It is not an assessment of whether a lender will approve you, and it does not account for your credit score, income or existing obligations.
Common questions
Is a balance transfer worth it?
Only when the interest you avoid is larger than the fee you pay to move the balance. Divide the total switching cost by the monthly EMI reduction to get the break-even month. Early in the tenure means real savings; late means the transfer mostly pays for itself.
What does a balance transfer actually cost?
Usually a processing fee as a percentage of the transferred balance, plus 18% GST on that fee, plus any fixed charges. A 1.5% fee on ₹1,50,000 is ₹2,250 — ₹2,655 once GST is added.
Does a balance transfer hurt my credit score?
Opening a new account and closing an old one can move your score for a while, and a hard enquiry is usually recorded. Paying the new balance on time is what matters over the following months. This page models cost, not score impact.
Is a 0% promotional balance transfer always the best option?
No. A 0% promotional period still carries a transfer fee, and the rate afterwards can be higher than the one you left. Work out whether you will clear the balance inside the promotional window first.
Can I transfer a credit card balance to a loan?
Many lenders offer this, and it is often the larger saving because card rates are far above personal loan rates. The arithmetic does not change: compare total interest before and after, then subtract what the switch costs.
