We read 50 credit card statements. Here’s where ₹8,000 a month disappears.
We asked fifty people — friends, colleagues, a few readers — if we could look at one credit card statement each. Most paid on time. A few paid the minimum. A handful had “no-cost EMIs” running. None of them thought they had a problem.
Across those fifty statements, the average leak came to around ₹8,000 a month. Most people couldn’t say where it was going if asked. Here are the four lines where it actually leaves.
The industry got big while nobody was looking
India had roughly 11.1 crore credit cards outstanding by mid-2025, climbing to about 11.5 crore by November. Indians spent ₹11.1 lakh crore on credit cards in the first half of 2025 alone; September 2025 set an all-time monthly high of ₹2.17 lakh crore. The card base has grown from 78 million cards to around 115 million.
That’s a lot of money moving through a product most people don’t fully read the terms of. Statistically, that includes you.
Leak 1: the minimum-due trap
Find the “Minimum Amount Due” line on your statement. That’s leak one, and nobody at the bank explains it when you sign up: pay only the minimum, and interest is charged on the full original balance, from the date of purchase, until it’s paid off completely — not on whatever’s left after your payment.
| Metric | Figure |
|---|---|
| Monthly rate (typical Indian card) | 3–3.5% |
| Effective annual rate | 36–48% |
| Interest paid over 12 months | ~₹16,600 |
| Principal actually reduced | ~₹5,000 |
₹16,600 paid. The debt moved by ₹5,000. Check next month’s statement for a “Finance Charges” line — that’s this leak, in real time.
Leak 2: the “no-cost” EMI lie
A ₹1 lakh phone on a 12-month no-cost EMI reads as ₹8,333 a month and feels free. Read the statement line by line and it isn’t — the same mechanics show up across ordinary EMI stacking generally.
| Line item | Amount |
|---|---|
| 12 EMIs | ₹1,00,000 |
| GST on the bank’s notional interest | ~₹1,467 |
| Processing fee | ~₹199 |
| GST on the processing fee | ~₹36 |
| True extra paid, on a “zero cost” purchase | ~₹1,702 |
The mechanism: the retailer absorbs the headline interest as a marketing cost, and recoups it by selling more units. You still pay the fees, and you still take on a 12-month liability. “No-cost EMI” is a discount traded for a debt — a fine trade, if you knew you were making it.
Leak 3: cash advances, late fees, annual fees
Pulling cash out on a credit card carries a fee of 2.5–3% of the withdrawal, minimum ₹300–500 — and interest starts the second the cash leaves the ATM, with no grace period at all. A ₹200 late-night withdrawal can easily cost ₹500 in fees before any interest is counted.
Late payment fees run ₹400–1,300 depending on the outstanding amount; RBI data points to Indians paying upwards of ₹5,000 crore a year in credit card interest in aggregate, a meaningful share of it late fees. And annual fees have a habit of showing up after a telecaller promised “zero charges” on a call with no paper trail to point back to — the same way a forgotten subscription renews for months before anyone notices.
Three small leaks that look accidental. They’re the business model.
Leak 4: the rewards you never actually use
A typical card earns 4 points per ₹150 spent. On ₹1 lakh of spending, that’s roughly 2,000 points; at about ₹0.50 per point in redemption value, that’s ₹1,000 — a 1% rebate, and only if you actually redeem before the points expire or the program devalues. Most people don’t.
Merchants fund those rewards through interchange fees of roughly 1.5–3% per swipe, which get passed back into prices for everyone. Even someone who never carries a card is partly funding someone else’s reward points. Rewards are worth using if you’re disciplined about paying in full — not a reason to spend more.
What ₹8,000 a month actually looks like
| Source | Monthly |
|---|---|
| Finance charges from carrying a balance | ~₹2,500 |
| “No-cost” EMI overhead and processing | ~₹1,700 |
| Late fees and cash advances | ~₹1,200 |
| FX markups and reward-driven overspend | ~₹2,600 |
| Total | ~₹8,000 |
The fix is boring on purpose:
- Pay the full statement balance, every month. Never the minimum, unless carrying a balance is a conscious choice.
- Avoid cash advances entirely — there's no interest-free window on them at all.
- Read the no-cost EMI screen line by line before confirming, GST and processing fee included.
- Treat rewards as a small bonus, never a strategy for spending more.
All four depend on noticing a charge in the month it lands, which is why most people delegate the watching to an app. An app that reads your card alerts out of the SMS inbox is asking for the whole inbox, not the bank's messages, and whether that is safe to grant deserves a deliberate answer rather than a reflex tap.
Discipline only works when you can actually see what’s happening. TLDR Money will read every line on your statement, flag finance charges the moment they hit, separate “no-cost” EMI overhead from real spending, and catch cash advance fees — one screen, showing exactly what your card cost you this month.

FAQ
Why does paying only the minimum due cost so much?
Because your bank charges interest on the full original balance, from the date of purchase, until it’s paid off completely — not on whatever’s left after your payment. On a ₹30,000 balance with only minimum payments, a typical 12 months looks like ₹16,600 paid in interest while the principal moves by only about ₹5,000. Indian credit cards generally charge 3–3.5% a month, an effective 36–48% a year.
Is a no-cost EMI on a credit card actually free?
No. On a ₹1 lakh purchase over 12 no-cost EMIs, the real extra cost — GST on the interest the bank notionally charges, the processing fee, and GST on that fee — comes to roughly ₹1,702. Cancel it early and a foreclosure fee plus another month of interest and GST can add close to ₹900 more. The retailer absorbs the headline interest as a marketing cost; you still pay the fees and take on a 12-month liability.
How much do credit card rewards actually save you?
Around 1% of spend, and only if you actually redeem the points before they expire or the program devalues. On a typical card earning 4 points per ₹150 spent at roughly ₹0.50 per point, ₹1 lakh of spending returns about ₹1,000. That reward pool is funded by interchange fees of 1.5–3% per swipe that merchants pass into prices for everyone — so even people who never use a card are partly funding it.
What’s the safest way to use a credit card?
Pay the full statement balance every month, never just the minimum. Avoid cash advances entirely — the fee and interest start immediately, with no grace period. Read a no-cost EMI screen line by line before confirming. And treat rewards as a small bonus on spending you were already doing, not a reason to spend more.
