What Is Cap-Adjusted Cashback (And Why Advertised Rates Lie)

That 5% card? It's probably earning you 1.8%. Here's the math banks don't want you to do.

Every credit card in India advertises a headline reward rate. '5% cashback!' '10x reward points!' '33% savings!' These numbers aren't lies exactly. They're just not the numbers you'll actually experience. The real number — what we call the cap-adjusted rate — is almost always lower. Sometimes dramatically lower.

Why Headline Rates Are Misleading

Credit cards use caps, minimum transaction amounts, category exclusions, and redemption friction to limit what you actually earn. A card advertising 5% cashback might cap that at ₹500/month. A card offering 10x points might exclude fuel, rent, and insurance. A card promising ₹5,000 in annual rewards might require you to jump through redemption hoops that make ₹3,000 of those points expire before you use them.

A Real Example

SBI Cashback Card: 5% on online transactions. Cap: ₹5,000 per quarter in cashback (dropping to ₹2,000 from April 2026). After cap: 0%. So if you spend ₹50,000 online in a month, your first ₹1 lakh equivalent earns 5%, and everything after earns nothing. Your actual effective rate on ₹50,000 online spend: 5% (since you're under the cap). But if you spend ₹1.5 lakh online: you earn ₹5,000 cashback on ₹1.5 lakh. That's 3.3% — not 5%.

Spend ₹2 lakh online? ₹5,000 on ₹2 lakh = 2.5%. The more you spend, the lower your effective rate drops. The headline said 5%. Reality says something very different for heavy spenders.

What Cap-Adjusted Rate Actually Measures

Cap-adjusted cashback is your total rewards earned divided by your total spend, after accounting for every cap, exclusion, minimum transaction, and redemption condition. It's the number that tells you how much you actually kept. Not how much the bank said you'd earn. Not the theoretical maximum. The actual, real, in-your-pocket return.

How to Calculate Yours

Step 1: Check your last 3 months of credit card statements. Step 2: Add up total cashback or reward value received. Step 3: Add up total spend. Step 4: Divide. If your card advertises 5% and your actual rate is 1.8%, you're not doing anything wrong — that's what the card actually delivers for your spending pattern.

Why This Matters for Card Choices

When comparing cards, never compare headline rates. Compare cap-adjusted rates for YOUR spending pattern. A card offering 2% with no cap often beats a card offering 5% with aggressive caps — depending on how much you spend and where. Our Compare tool calculates cap-adjusted returns automatically when you enter your real spending. That's the number you should compare. Everything else is marketing.
