Forex markup decoded: why your 5% cashback card pays 1.5% on USD spend

You signed up for the SBI Cashback because the 5% online rate on Amazon was unbeatable. Now you're paying ChatGPT $20/month, Anthropic $50/month, Vercel $20/month, and Notion $16/month. Total USD spend: $106/month ≈ ₹8,840.

You assume you're earning 5% on it. You aren't.

You're earning roughly 1.5%. The other 3.5% is forex markup — the bank's hidden tax on every USD transaction. It is the single biggest leak in Indian cardholders' SaaS spend, and almost nobody talks about it because banks don't itemize it on statements.

This post is the actual markup of every major India card, the 4 cards that don't charge it, and how to think about USD subscriptions for the rest of 2026.

What is forex markup?

When you swipe an Indian rupee credit card on a USD merchant, the bank does two things:

1. Currency conversion at the Visa/Mastercard interbank rate (call it ₹83.20/USD on a given day).
2. Adds a forex markup of 1.5% to 3.5% on top of the converted amount, then bills you in rupees.

A $50 charge at ₹83.20 interbank converts to ₹4,160. With a 3.5% markup, you actually pay ₹4,305.60. The ₹145.60 difference is the bank's profit, and you never see it itemized — it just appears in your statement as a slightly-higher-than-expected rupee figure.

The reward calculation then runs on the post-markup amount:

• 5% cashback × ₹4,305.60 = ₹215.28 earned.
• Net cost: ₹4,305.60 − ₹215.28 = ₹4,090.32 for a $50 transaction.
• Effective rate vs interbank: (4,160 − 4,090.32) / 4,160 = 1.67% net benefit.

The "5% cashback" card delivered 1.67% net on this USD spend. The forex markup ate the rest.

Actual markup of every major India card (2026)

This data is from issuer disclosure documents + verified by our editorial team. Markup is on USD; INR transactions have no markup but EUR/GBP/SGD may differ slightly.

| Card | Annual fee | Forex markup | Effective rate for $50 spend | |---|---|---|---| | HDFC Pixel Play | ₹0 (lifetime free) | 0.00% | 0% (no rewards either, but 0% cost) | | NiyoX Visa Signature (Equitas Bank co-brand) | ₹0 | 0.00% | 0% (debit + no rewards) | | IDFC First Wealth | ₹0 (LTF) | 1.99% | 1.0% (10X on intl spend = 3.3% gross, 1.31% net of markup) | | HSBC Premier | ₹12,000 | 1.99% | 1.6% (3X miles = 3.5% gross, 1.51% net) | | HDFC Infinia | ₹12,500 | 2.00% | 2.0% (general rate 3.3X = 3.3% gross, 1.3% net; on Smartbuy USD: 5%+ via 10X cap) | | HDFC Regalia Gold | ₹2,500 | 2.00% | 1.5% | | Axis Magnus / Reserve | ₹12,500 | 2.00% | 4.0% (24X EDGE on intl is uncapped = 4.8% gross, 2.8% net) | | ICICI Sapphiro | ₹3,500 | 1.99% | 1.5% | | SBI Cashback | ₹999 | 3.50% | 1.5% (5% cashback − 3.5% markup) | | HDFC Millennia | ₹1,000 | 3.50% | 1.5% (5% on intl is also 5% gross, 1.5% net) | | HDFC Diners Club Black | ₹10,000 | 2.00% | 3.5% (10X on Smartbuy USD = 10% gross, 8% net minus annual fee) | | Amex Platinum (India) | ₹66,000 | 3.50% | 2.0% (5X intl spend = 5% gross, 1.5% net minus ₹66K fee) | | Standard Chartered Ultimate | ₹5,000 | 3.50% | 0.5% (the worst common combo) |

The headline pattern: 3.5% markup is the default at SBI, HDFC mid-tier, and most legacy cards. 2% is the premium-tier ceiling. 0-2% is achievable but requires the right card.

The 4 zero/near-zero markup cards for SaaS spend

1. HDFC Pixel Play (0% markup, ₹0 annual fee)

The honest winner for pure USD spend. Launched in 2024, refreshed in 2026.

• 0% forex markup on USD merchant transactions
• 0.5% cashback on UPI transactions in INR
• No annual fee, ever
• No income gate, easy to qualify

The catch: it earns ~0% on the USD spend itself (no reward rate). Use it as a dedicated USD-paying card alongside another card for INR rewards.

For a SaaS founder paying $200/month in tools, Pixel Play saves you ₹100/month vs a 3.5% markup card, with zero cost. Over a year: ₹1,200 saved.

2. IDFC First Wealth (1.99% markup, ₹0 LTF)

The all-rounder with USD support. Lifetime free, no income gate, decent rewards everywhere.

• 1.99% forex markup
• 10X reward points on international spend (~3.3% gross → 1.31% net)
• 0% surcharge on UPI
• Concierge + lounge access on a free card (unusual)

Best for founders who want one card that handles both INR and USD reasonably well, without the Pixel-Play approach of needing two cards.

3. NiyoX Equitas Visa Signature (0% markup, debit-only)

The traveler's debit card. Technically a debit linked to an Equitas savings account, but works as a Visa Signature internationally.

• 0% markup on USD/EUR/GBP swipes and ATM withdrawals
• Up to ₹1L/month FX-free withdrawals abroad
• No annual fee

The catch: debit, not credit. Won't help with credit-card welcome bonuses or reward earn, but for "I just want to buy in USD without paying markup," it is the cleanest option.

4. Axis Magnus / Reserve (2% markup, premium income gate)

The premium-tier USD spender's pick. ₹15L+ income required.

• 2% markup (vs 3.5% standard)
• 24X EDGE Reward points on international spend, uncapped
• Marriott Bonvoy 5:4 transfer for redemption upside
• Effective rate post-markup: ~3-4% net on USD via transfer-partner redemptions

This is the only card where USD spend genuinely earns competitive rewards (3-4% net), not just "less of a haircut."

The optimization

For a typical SaaS founder ($200/month USD spend = $2,400/year):

| Setup | Forex markup paid | Net cost vs interbank | |---|---|---| | SBI Cashback (default) | $84 | $84 lost to markup | | HDFC Pixel Play (no rewards) | $0 | $0 lost | | IDFC First Wealth | $48 | $16 lost (markup minus 1.31% earn) | | Axis Reserve | $48 | $48 net earn (markup minus 2.8% earn) |

The annual delta between SBI Cashback and Pixel Play is $84 (~₹7,000/year) on $2,400 USD spend. That's the cost of using the wrong card for SaaS subscriptions.

For Indian founders running on $5K-15K/year of USD tooling spend, the delta scales to ₹15-30K/year — significant money.

What to do today

1. Check your last 3 months of statements. Add up your USD line items. If it's > $50/month, you have a markup problem worth solving.
2. Apply for HDFC Pixel Play if you don't have it. Lifetime free, no income gate, takes 5 minutes online. Use it exclusively for USD merchants.
3. Use your primary rewards card for INR. Pixel Play earns nothing on rewards; you only use it to dodge the markup.
4. For premium spenders ($500+/month USD): Apply for Axis Reserve. The 2% markup + 24X EDGE earn on USD is currently unmatched.
5. Skip the "international fee waiver" trap. Some premium cards offer "international fee waiver on ₹10L+ annual spend" — this waives a fixed annual fee, NOT the per-transaction markup. The markup still applies.

The CardPolo position

We have a separate forex calculator that takes your monthly USD spend + card and shows the actual markup paid. Polo Brain will recommend the right card for any specific USD merchant transaction in plain English.

The 3.5% forex markup is the single biggest hidden cost in Indian credit-card use. Fix it once and you stop bleeding $1-2K/year on routine SaaS subscriptions.
