You filled fuel or bought an IRCTC / railway ticket on the card, paid the Total Amount Due, and still saw an extra ₹10–₹25 or 1–2.5%. That line is a surcharge (sometimes called a convenience or acquiring surcharge). It is not interest, not the 3.5% forex markup, and not a cash-advance fee.
Banks print it in the same tariff table, so statements mix all four ideas. This article keeps them apart.

Surcharge in one sentence
A surcharge is an extra amount added because of the merchant category (fuel pump, railway) and the acquiring bank’s rules — billed to you as part of the transaction or as a follow-on line.
Public MITC language that still shows up on many inserts:
- Railway: ₹25 or 2.5% of the transaction, whichever is higher
- Petrol: ₹10 or 1% of the transaction, whichever is higher
- The rate may vary depending on the acquiring bank
Your card’s welcome brochure may waive or cap these. The acquirer (the pump’s or IRCTC’s bank) can still levy something. Always read the current schedule.
Why “whichever is higher” hurts small tickets
| Spend | Petrol rule (₹10 or 1%) | You pay (fee only) | Effective % |
|---|---|---|---|
| ₹200 fuel | max(10, 2) | ₹10 | 5.0% |
| ₹500 fuel | max(10, 5) | ₹10 | 2.0% |
| ₹1,000 fuel | max(10, 10) | ₹10 | 1.0% |
| ₹3,000 fuel | max(10, 30) | ₹30 | 1.0% |
| Spend | Railway rule (₹25 or 2.5%) | You pay (fee only) | Effective % |
|---|---|---|---|
| ₹400 ticket | max(25, 10) | ₹25 | 6.3% |
| ₹1,000 ticket | max(25, 25) | ₹25 | 2.5% |
| ₹4,000 ticket | max(25, 100) | ₹100 | 2.5% |
Small top-ups and short-haul tickets are where the floor (₹10 / ₹25) is worse than the percentage.
GST may apply on the surcharge line depending how it is billed.
Petrol vs railway vs everything else
| Petrol surcharge | Railway surcharge | Forex markup | Cash advance | |
|---|---|---|---|---|
| Typical public figure | ₹10 or 1% | ₹25 or 2.5% | about 3.5% overseas | about 3% (min ~₹300) |
| Interest-free if you pay in full? | Usually yes on the fuel purchase | Usually yes on the ticket purchase | Markup stays; interest can still be 0 | No — interest from day one |
| Why it exists | Fuel MCC / acquirer cost | Rail / IRCTC MCC | Currency conversion | You took cash |
| Waivers | Some cards refund surcharge as points or statement credit, often with a monthly cap | Some cards waive IRCTC convenience fee; not all | Forex cards cut this | Almost never waived |
A surcharge waiver card does not automatically waive forex or cash. Those are other rows in the same tariff.
Does paying in full remove the surcharge?
No.
Same logic as forex:
- Total Amount Due on time → you keep purchase grace (no APR on that fuel or ticket).
- The ₹10 / 1% or ₹25 / 2.5% is still a merchant-category fee.
If you pay only MAD, you can get surcharge + revolving interest. That is the expensive stack. MAD · APR · Grace.
How it looks on the statement
Common patterns:
- One inflated fuel line — surcharge baked into the pump amount.
- Two lines —
IOCL / HPCL / BPCL …plusFUEL SURCHARGEorCONVENIENCE FEE. - IRCTC — ticket amount + IRCTC convenience fee + sometimes a card surcharge.
- Reversal / waiver a few days later if your card has a fuel-surcharge refund (points or credit), often capped per month.
If you expected a waiver and none posted by the next cycle, check the cap, MCC (some “fuel” shops code as grocery or fleet), and whether the card was a corporate / add-on excluded from the offer.
Acquiring bank: why two pumps charge differently
The MITC line “the rate of surcharge may vary depending on acquiring bank” means:
- Pump A’s bank may add 1%.
- Pump B may add a flat rupee fee.
- A third may pass through a different fuel-surcharge programme.
You cannot see the acquirer on the receipt easily. If one pump is consistently cheaper on the same card, that is why.
Worked example: ₹2,200 petrol + ₹1,800 IRCTC, full pay
Using the public floors:
- Petrol fee = max(10, 1% × 2,200) = ₹22
- Railway fee = max(25, 2.5% × 1,800) = ₹45
- Finance charge if TAD paid on time = ₹0
Extra cost ≈ ₹67 (+ GST if levied). Annoying, not an APR event.
If the same ₹4,000 instead revolved for a month at 3.49%: interest ≈ ₹140 plus those surcharges.
Short FAQ
Why is there a charge on petrol if credit cards are “interest free”?
Interest-free is about APR. Fuel often has a category surcharge. Different fee.
Is petrol surcharge 1% or ₹10?
In many older public tariffs, whichever is higher. Tiny fillings pay the ₹10 floor.
Is IRCTC convenience fee the same as the bank’s railway surcharge?
Not always. You can see IRCTC’s own convenience fee and a card/acquirer surcharge. Read both lines.
Will this hurt CIBIL?
The surcharge itself is just a billed amount. Missing MAD is what gets reported. Late fees.
Do UPI or debit cards avoid this?
Often cheaper on fuel and rail. Some credit products refund the surcharge; compare the net after waiver caps, not the sticker 1%.
I was charged 3.5% on a railway booking from a foreign site.
That is likely forex / overseas merchant, not the domestic rail slab. Forex article.
What you should do
- For routine fuel, prefer a card with a real surcharge waiver (and know the monthly cap) or pay UPI/debit.
- Avoid ₹200–₹300 credit-card top-ups — the ₹10 floor is a terrible rate.
- On IRCTC, check the break-up before you confirm.
- Still pay Total Amount Due so you do not add APR.
- If a waiver is missing, wait one cycle, then raise a dispute with the receipt inside the MITC window (often ~21 days).
Educational explainer, not a live tariff. Floors of ₹10 / ₹25 and rates of 1% / 2.5% come from widely circulated MITC language and change by issuer, acquirer, and year. Confirm your schedule of charges.
