The real cost of paying only the credit card minimum due

A ₹50,000 balance paid at the minimum due, at a typical 42% annual rate, takes almost 17 years to clear and costs over ₹1.1 lakh in interest — more than double the original balance. Here is exactly why, and what changes it.

Why the minimum due is a trap, not just a slow path

RBI does not set a minimum-due percentage; each issuer sets its own formula in its Most Important Terms and Conditions. A common pattern is the higher of a small percentage of your outstanding balance — often around 5% — or a fixed floor amount, often ₹200-500, and issuers typically also include that month's interest, taxes and fees and any EMI instalments due. That structure means the minimum due shrinks every month as your balance shrinks, unlike a loan EMI, which stays fixed.

This is the actual trap: because both the payment and the balance keep falling together, a huge share of every payment keeps going to interest rather than principal, for years. Card interest rates in India commonly run 30-45% p.a. — many multiples of even a personal loan rate — so the interest owed each month stays large relative to a shrinking minimum payment.

The worked example

Take a ₹50,000 outstanding balance at 42% p.a., with a 5% minimum due and a ₹200 floor, and no new spending added:

Two things stand out. First, paying the minimum only takes over five times longer than paying a fixed amount equal to that very first minimum payment — because the minimum keeps shrinking while a fixed payment does not. Second, adding just ₹1,000 a month on top of the minimum cuts the payoff time by roughly 82% and saves about ₹80,000 in interest.

This is not a fringe risk regulators ignore: RBI's Credit Cards and Debit Cards: Issuance and Conduct Directions, 2025 require every billing statement to carry a warning that making only the minimum payment stretches repayment over months or years with compounded interest (para 23(3)), and require issuers to publish illustrative examples in the welcome kit and on their website (para 23(4)). Your own card's minimum-due formula is in the Most Important Terms and Conditions your issuer gave you.

A smaller balance is not automatically a small problem

Even a ₹20,000 balance at the same 42% rate, paid at the minimum only, takes almost 12 years and costs roughly ₹40,333 in interest — double the original balance again. The mechanism does not depend on the balance being large; it depends on the gap between the interest rate and the shrinking payment.

Can paying the minimum due ever make the balance grow?

Not on a card that follows RBI's current rules. The card Directions (para 23(2)) require issuers to set the minimum amount due so that there is no negative amortisation — paying it should never let the balance grow — and forbid charging interest on unpaid taxes, levies or charges. So on a real statement, paying the minimum should not, by itself, make the balance grow. It can still reduce the balance very slowly — or, if the minimum only just covers interest and charges, barely at all — and new spending or new fees (annual fee, forex markup) can still add to it.

Our calculator will still show a "never clears" result if you enter a minimum percentage too low to cover the monthly interest. Treat that as a hypothetical that a compliant card should not produce. If your actual statement shows the balance rising while you pay the full minimum due and add no new spending or new fees, ask your card issuer to explain it in writing.

What actually changes the outcome

• Add a fixed amount every month, however small. The example above shows ₹1,000 extra cutting the payoff time by more than 80%. Consistency matters more than the size of the extra amount.
• Stop new spending on the card while paying it down. Every rupee of fresh spending resets and extends the calculation above.
• Consider a balance transfer to a lower rate if one is genuinely available to you, factoring in the processing fee and any charges — the calculator shows whether the switch pays off net of costs.
• Consider converting to a fixed-tenure EMI if your issuer offers it — see the credit card EMI calculator for the real cost including fees, since a fixed EMI behaves like the "fixed ₹2,500/month" row above rather than the ever-shrinking minimum.

Common questions

Does paying only the minimum due hurt my credit score?

Not directly, as long as you pay it on time — a minimum-due payment counts as "paid on time" for reporting purposes. The damage here is financial, not to your score: a persistently high outstanding balance and utilisation can affect your score through other measures, but the minimum-due mechanic itself is a cost problem, not a reporting problem.

Is 42% p.a. a realistic credit card rate in India?

It is within the commonly quoted range of roughly 30-45% p.a. for revolving credit card balances in India, though your specific card's rate can differ — check your card's Most Important Terms and Conditions document or your statement for the exact rate.

Why does the minimum shrink instead of staying fixed like an EMI?

Because it is defined as a percentage of the current outstanding balance (subject to a floor), not as a fixed instalment calculated up front the way a loan EMI is. That design is exactly what makes the minimum-only path so slow.

Is there a point where paying extra stops mattering?

No — every extra rupee reduces the principal balance that the next month's interest is calculated on, so it always helps, though the marginal benefit is largest early, before compounding has had years to work against you.
