Credit Card Minimum Due: A 28-Year Contract You Never Signed

The SMS is gentle: “Minimum amount due: ₹5,000. Pay now to stay stress-free.” Anita Bhatt, who runs a boutique in Surat, pays it, feels responsible, and moves on. Nobody tells her what she just signed up for: at this pace, her ₹1 lakh balance will take 28 years to clear, and she will hand the bank about ₹4.7 lakh — for money she has already spent. The minimum due is not a payment plan. It is a subscription to interest.

Anita is a composite character based on patterns common among small-business owners carrying revolving card balances in India — the SMS-driven minimum payment, the balance that never quite falls. She is not a real person, but the warning RBI requires her bank to print on every single statement she has ever received is real, and she has never once read it.

The machinery: a number engineered to almost fail

Credit card interest runs at 36–48% a year — call it 3.5% a month. The minimum due is typically 5% of the balance. Watch what happens in month one: on ₹1,00,000, interest is ₹3,500. GST at 18% on that interest adds ₹630. So ₹4,130 of Anita’s ₹5,000 payment evaporates into charges, and her balance drops by ₹870. The minimum is not sized to walk you out of debt; it is sized to keep the debt alive while technically not defaulting. That is not an accident of arithmetic. Someone chose 5%.

The state has a seat at this table

Notice the second charge: GST on the interest. When a lakh of card debt compounds at 42%, the government collects 18% of every interest charge, month after month, for 28 years. The most punishing consumer interest rate in the mainstream system is also a tax base. Nobody in that chain is in a hurry for Anita to be free.

The revolver is the business model

Card companies have a name for people who pay in full: “transactors” — tolerated, barely profitable. People like Anita are “revolvers”, and they are the profit centre. The reward points, the limit increases that arrive unasked, the EMI-conversion offers on large purchases — all are instruments tuned to one goal: keep the balance revolving. The interest-free period you think you have vanishes entirely the moment you carry any balance; interest then runs from each transaction’s date.

The warning that is on Anita’s statement right now

Here is what makes this story different from a simple case of a bank exploiting a customer: RBI does not leave this to the card issuer’s discretion. The Master Direction — Credit Card and Debit Card — Issuance and Conduct Directions, 2022 requires a specific sentence, close to verbatim, on every single billing statement issued in India: “Making only the minimum payment every month would result in the repayment stretching over months/years with consequential compounded interest payment on your outstanding balance.” The same direction requires the same warning in the Welcome Kit handed over when the card is first issued. Anita’s bank has been printing this sentence on her statement every month for years. She has never read it.

The same Master Direction goes further than a warning sentence. It requires that “the terms and conditions for payment of credit card dues, including the minimum amount due, shall be stipulated so as to ensure there is no negative amortization” — in plain language, the minimum due is not allowed to be set so low that unpaid interest and charges quietly get added to next month’s principal, growing the balance even while the cardholder keeps paying. RBI’s own worked illustration in the annex to the direction sets a floor: if the total unpaid interest and charges for a cycle come to roughly ₹250, the minimum due cannot be set lower than that ₹250, precisely so the “minimum” cannot mathematically shrink the debt-servicing floor below what is already accruing.

What the calculator settles for Anita: enter her real outstanding balance, her card’s actual interest rate and her bank’s minimum-due percentage, and it tells you the payoff year and total interest — the same arithmetic the RBI warning gestures at in one sentence, made concrete with her own number instead of a generic caution.

How to protect yourself

Treat the minimum due as what it is: the bank’s preferred outcome. Pay in full, always; if you cannot, pay the absolute maximum you can and stop using the card until clear. Already deep? A personal loan at 12–16% to retire a 42% balance is not more debt — it is a two-thirds pay cut for your creditor. Run the calculator above with your real balance: seeing “28 years” printed against your own number does more than any lecture.

Frequently asked questions

Does paying the minimum protect my credit score?

It avoids a default mark, yes — while your utilisation stays maxed, which itself drags the score down. You are preserving the score’s floor, not its health.

Why does my bank keep raising my limit?

Because your behaviour marks you as profitable. A higher limit for a revolver is not a compliment; it is inventory expansion.

If RBI already requires a warning, why doesn’t it stop people like Anita?

Because a mandated sentence in small print at the bottom of a statement is a disclosure requirement, not a behavioural nudge sized to be noticed. RBI’s rule guarantees the information exists somewhere on the page; it does not guarantee anyone reads it before tapping “pay minimum due” in an app. The warning satisfies the regulation. It does not, on its own, change what most cardholders actually do.

What this does not mean

None of this means Anita’s bank broke any rule, or that minimum-due billing is illegal predation. It is a regulated, disclosed product feature, operating exactly as RBI’s own framework allows, with the warning sentence and the negative-amortization floor both present exactly as required. It also does not mean paying the minimum due is always the wrong call: in a genuine short-term cash crunch, paying the minimum rather than missing a payment protects your credit history, and that is a real, narrow use case the mechanism is not designed to punish. What it means is narrower and more useful: “compliant” and “in your interest” are two different tests, and a statement can pass the first while working against the second. Anita’s real protection was never the RBI warning sitting in small print — it was noticing what her own number, run through an actual calculation, was going to cost her.

Anita eventually paid off the balance in fourteen months using a personal loan at a lower rate, and now pays her card in full every cycle by design, not memory — an auto-debit set for the statement total, not the minimum due box the app defaults to.

Regulatory source: RBI’s Master Direction — Credit Card and Debit Card — Issuance and Conduct Directions, 2022 (published on rbi.org.in) sets the mandated warning legend and the no-negative-amortization requirement for minimum amount due. The GST-on-interest arithmetic, the revolver framing and the character of Anita are this article’s own.
