10. Credit Cards and CIBIL
Indian card mechanics, and how a credit record is actually built.
10.1 What a credit card is
An unsecured revolving loan on a roughly 30-day cycle. Unsecured means nothing is pledged, which is why the rate is the highest of any mainstream borrowing in India. Revolving means the balance carries forward and re-borrows automatically unless you clear it.
Two independent things are bundled into one product:
- A payment instrument with a free credit period, genuinely useful and free if used correctly.
- A very expensive loan facility: activated the moment you fail to pay the full statement amount.
Most of the harm comes from people using (1) and unintentionally activating (2).
10.2 Starting with no credit history
New borrowers (including new graduates and people returning from abroad) have no credit history, so lenders will not lend, so no history forms. Entry products that solve this:
- Secured credit card against a fixed deposit. Limit is typically 80%–90% of the FD; the FD continues to earn interest. Approval is near-automatic since the bank holds the collateral
- Student credit card
- Consumer durable loan: a small, short EMI on an appliance or phone
- Being reported as a co-applicant on a family loan, which does build your record (and your liability)
10.3 The billing cycle and the grace period
Statement cycle │←──────── ~30 days ────────→│
Purchases posted │ ▲ ▲ ▲ │
Statement generated │ │ ← statement date
Payment due │ │←── ~15–20 days ──→│ due date
- A purchase made the day after a statement date sits for the whole next cycle plus the payment window, up to about 45–50 interest-free days.
- A purchase made the day before a statement date gets only the payment window, about 15–20 days.
The grace period is conditional and all-or-nothing. It applies only if you pay the total amount due in full by the due date. Pay ₹1 less than the full amount, and:
- Interest is charged retrospectively from each transaction date, not from the due date
- New purchases lose the grace period entirely and start accruing interest immediately
- The grace period does not return until the balance is cleared in full
This is the mechanism people mean when they say credit card debt is hard to escape. It is not a penalty rate; it is the withdrawal of a subsidy.
10.4 The arithmetic
Indian card finance charges run 2.5%–4.0% per month.
| Monthly rate | Nominal APR | Effective annual rate |
|---|---|---|
| 2.5% | 30.0% | 34.5% |
| 3.0% | 36.0% | 42.6% |
| 3.5% | 42.0% | 51.1% |
| 4.0% | 48.0% | 60.1% |
Plus 18% GST on the interest and on every fee.
The minimum due
The minimum amount due is typically 5% of the outstanding balance. Paying it keeps your account current and protects your credit score, and does close to nothing to the debt.
₹1,00,000 outstanding at 3.5% per month, paying only the 5% minimum each month, with no new spending:
| After | Balance |
|---|---|
| 12 months | ~₹81,700 |
| 24 months | ~₹66,700 |
| 36 months | ~₹54,400 |
Three years, roughly ₹1,40,800 paid, and ₹54,400 still owing. The minimum due is engineered so that interest consumes most of the payment.
Cash withdrawal
Withdrawing cash on a credit card is the single most expensive routine transaction available to a retail customer in India:
- No grace period. Interest accrues from the withdrawal date.
- Cash advance fee of 2.5%–3% of the amount, minimum ₹300–₹500.
- GST at 18% on the fee.
Other charges
| Charge | Typical |
|---|---|
| Annual fee | ₹0–₹10,000, often waived on a spending threshold |
| Late payment fee | Slab-based, ₹100–₹1,300 |
| Over-limit fee | 2.5% of the excess |
| Foreign currency markup | 3.5% of the transaction, plus GST. Significant for engineers paying for cloud services, SaaS subscriptions or foreign travel |
| Dynamic currency conversion | If a foreign merchant offers to bill you in INR, the exchange rate applied is usually poor. Decline it |
| Rent payment via card | 1%–2% platform fee, frequently exceeding the reward earned |
| EMI conversion | Interest of 13%–18% p.a. plus a processing fee. Cheaper than revolving, still expensive |
10.5 Rewards, and when they are real
Reward rates in India typically run 0.5%–3.3% in value terms, higher on co-branded and travel cards.
The arithmetic is unambiguous: any reward rate is dwarfed by any interest rate.
Reward on ₹1,00,000 of spending at 2% = ₹2,000 gained
Interest on ₹1,00,000 revolved for 1 year = ₹51,100 lost
A card earns you money only if the balance is cleared in full, every cycle, without exception. Rewards are a rebate on money you were going to spend; they are never a reason to spend.
Points worth checking before optimising for rewards:
- Redemption value per point varies enormously; 1 point is not 1 rupee
- Points expire
- Categories are frequently excluded: rent, fuel, wallet loads, insurance, education, government payments, EMI conversions
- Milestone benefits require reaching a spending threshold, which distorts behaviour
- The annual fee must be netted off
10.6 The Indian credit bureau system
India has four RBI-licensed credit information companies:
- TransUnion CIBIL: the most widely referenced; "CIBIL score" is used colloquially for credit score generally
- Experian
- Equifax
- CRIF High Mark
Lenders report to them when you apply for credit, when credit is sanctioned, and on each payment. Different lenders report to different bureaus, so your scores will differ across bureaus.
The score
Range: 300–900. Broadly:
| Band | Reading |
|---|---|
| 750–900 | Strong; best rates and quickest approvals |
| 700–749 | Good |
| 650–699 | Fair; approval likely, rate less favourable |
| 550–649 | Weak |
| 300–549 | Poor |
| NA / NH | No history: a new borrower with no credit record |
What builds it
Published weightings vary between sources; the ordering is consistent even where the percentages are not:
| Factor | Approximate weight | What it measures |
|---|---|---|
| Payment history | 30%–35% | On-time payment across all accounts. The dominant factor |
| Credit utilisation | 25%–30% | Balance used as a proportion of total limit. Below 30% is the conventional guidance |
| Credit age and mix | ~25% | Length of history; a mix of secured (loans) and unsecured (cards) credit |
| New enquiries | ~20% | Hard enquiries from fresh applications. Several in a short period reads as distress |
Mechanics worth knowing
- Utilisation is measured on the statement date, not on the due date. Paying in full every month still shows high utilisation if you routinely spend near your limit before the statement generates. Making a mid-cycle part payment reduces the reported figure.
- Do not close your oldest card. Closing it shortens your credit age and reduces total available limit, raising utilisation on both counts.
- Accepting a limit increase lowers utilisation at the same spending level.
- Hard vs soft enquiry: applying for credit is a hard enquiry and affects the score. Checking your own report is a soft enquiry and does not.
- You are entitled to one free full credit report per bureau per calendar year under RBI rules. Four bureaus, four free reports.
- Errors are common: closed loans still showing open, accounts that are not yours, incorrect defaults. Both the bureau and the reporting lender have defined timelines to investigate disputes.
- Being an add-on cardholder on someone else's card does not build your own history. A secured card against a fixed deposit does.
Three rules cover most of it: do not pay interest, do not miss a payment, do not spend too much of your limit.
10.7 Credit card debt as a financial position
Placed against the alternatives:
Guaranteed return from clearing card debt at 3.5%/month ≈ 51.1% effective, risk-free, tax-free
Long-run historical equity return, annualised ≈ 12%, volatile, taxed
EPF declared rate = 8.25%
No legitimate Indian investment returns 51% with certainty. Repaying a revolving card balance therefore dominates every other use of the same rupee, with one qualification: the emergency fund may take precedence, because being without liquidity is what causes people to revolve a balance in the first place.
The behavioural failure mode is mental accounting (see §1.8): maintaining a ₹2 lakh "travel fund" earning 3% while revolving ₹80,000 at 51%. Money is fungible. The buckets are in your head, not in the arithmetic.
10.8 What the 2026 rules give the cardholder
The Reserve Bank amended the credit card framework with effect from 2026. Two changes materially improve the borrower's position:
Three-day grace period before penalty
Banks must allow at least three days past the due date before:
- reporting the account as past due to credit bureaus, and
- levying late payment charges
Clear the dues within that window and the late fee is waived and the bureau is not informed.
No interest on unpaid fees and taxes
Previously, an unpaid late fee (and the GST on it) was added to the outstanding balance and itself began accruing interest at card rates. Under the amended rules, unpaid charges, levies and taxes cannot be added to the balance on which interest is computed.
This removes a compounding-on-penalties mechanism that could turn a ₹500 late fee into a materially larger sum.
Also in force
- Late payment charges apply only to the unpaid amount, not the whole bill.
- Card network choice: customers must be offered a choice of card network (Visa, Mastercard, RuPay, Diners) rather than having one imposed, for eligible portfolios.
- Card closure within 7 working days of a valid request, with ₹500/day compensation for delay.
- Unsolicited cards and unrequested limit increases are prohibited: explicit consent is required.
- Tokenisation of card-on-file data at merchants is mandatory; merchants may not store raw card numbers.
10.9 Checklist
- Pay the total amount due, never the minimum; set an auto-debit for the full statement amount
- Know your statement date and your due date; they are different
- Keep reported utilisation below 30%; make a mid-cycle payment if your spend is close to the limit
- Never withdraw cash on a credit card
- Pull your free credit report from all four bureaus once a year and dispute errors
- Do not close your oldest card
- Decline dynamic currency conversion abroad; check the 3.5% forex markup
- Treat any revolving balance as the highest-priority claim on spare cash after the emergency fund
