The minimum due is a product, and you are what it sells

Paying 5% of the balance on a card charging 42% a year takes over a decade to clear and costs more than the original purchase. The mechanics, and how to get out.

A credit card statement shows two figures prominently. The Total Amount Due, and the Minimum Amount Due — usually smaller, often bolder, and positioned to be the one your eye lands on.

That placement is deliberate. The minimum due is not a concession to people having a hard month. It is the mechanism by which a card becomes profitable, and it is engineered to be affordable enough that you keep paying it and small enough that you never finish.

The arithmetic

The minimum is typically 5% of the outstanding balance, subject to a floor of a few hundred rupees. Card interest runs 3% to 3.5% a month — 42% a year, compounded monthly.

Owe ₹1,00,000 and pay the ₹5,000 minimum:

• Interest for the month, at 3.5%: ₹3,500
• Principal repaid: ₹1,500

You paid ₹5,000 and reduced the debt by ₹1,500. Seventy per cent of the payment was rent on money you already spent.

Keep paying the minimum, which shrinks as the balance does, and the ₹1,00,000 takes more than fifteen years to clear. Total interest paid: comfortably more than the original ₹1,00,000. The dinner, the phone, the flight — you paid for all of it twice, and waited fifteen years to finish.

The clause that makes it worse

There is a detail in the terms that most cardholders discover only after it has cost them.

The interest-free period — the 45-to-50-day grace between a purchase and its due date — applies only if you pay the statement in full. Miss that by a single rupee and the grace period is revoked. Not just for the unpaid balance: for everything.

Which means:

• Existing balances start accruing interest from each original transaction date, retroactively.
• New purchases accrue interest from day one. No grace, no float.
• The grace period does not return until you have cleared the entire balance and the next statement cycle completes.

So a person carrying ₹1,00,000 who then buys ₹5,000 of groceries is charged interest on those groceries from the moment they were bought. This is why balances grow even when people believe they are paying them down: the minimum reduces the old debt slowly while every new spend starts compounding immediately.

What ₹42,000 a year actually means

Sitting between a 12% equity return and a 42% card rate is a 30-point gap.

Somebody carrying ₹2,00,000 on a card while running a ₹15,000 monthly SIP is paying roughly ₹84,000 a year in card interest to earn roughly ₹21,600 in expected investment return. Net loss: ₹62,000 a year, plus a large amount of anxiety.

There is no investment, no side income and no tax strategy that outruns 42%. Clearing card debt is the highest-return financial act available to almost anyone who has it.

Getting out

Stop using the card. Not "use it less" — stop. Remove it from every saved payment method, every subscription and every wallet. Debt cannot be cleared while new charges are landing without a grace period. Use a debit card until the balance is zero.

Pay far more than the minimum. The relationship is dramatic. On ₹1,00,000 at 42%:

Doubling the payment does not halve the time; it cuts it by more than two thirds, because the proportion going to principal rises with every rupee above the interest charge.

Refinance if the balance is large. A personal loan at 14% to 16% to clear a card at 42% cuts the interest cost by roughly two thirds and imposes a fixed end date, which the card deliberately lacks. A balance transfer to another card at 0% to 12% for three to six months works if — and only if — you clear it within the promotional window, since the reverting rate is usually as bad as the original.

Both carry the same danger: the card now has an empty limit on it. Refinancing and then re-spending is the sequence that turns one problem into two, and it is extremely common. If you are not prepared to close the card or freeze it, do not refinance it.

Attack the highest rate first if you hold several. And if you also have a savings balance earning 3%, use it. Holding ₹50,000 at 3% while paying 42% on ₹50,000 costs you about ₹19,500 a year for the comfort of seeing a balance.

The one rule that prevents all of this

Pay the statement in full, every month, without exception. Used that way, a credit card is genuinely good: 45 days of free credit, purchase protection, rewards, and a clean credit history.

The instant it is not paid in full, it becomes the most expensive borrowing an ordinary person has access to — considerably worse than a personal loan, and worse than most things people would describe as predatory.

The card is not the problem. The minimum due is.
