How to Compare Credit Cards: A Practical Framework
Updated 23 July 2026
The advertised reward rate is the number every issuer leads with, and it's the least reliable way to compare cards, because it ignores caps, category restrictions, and fees. Here's a sturdier framework.
1. Start from your actual spend, not the card's marketing
Estimate your monthly spend by category (dining, groceries, fuel, travel, online shopping, everything else) before looking at any card. A card's headline rate only matters on the categories it actually rewards — a 5% dining card is worthless to you if you rarely eat out.
2. Net out the annual fee, not just the reward rate
Multiply your realistic spend by the card's reward rate (watching for category caps) to estimate annual reward value, then subtract the annual fee (net of any waiver you'll actually clear). Compare that net number across cards, not the raw reward percentage.
3. Check eligibility before you fall in love with a card
Minimum income, credit score band, employment type, and age requirements vary a lot between cards at the same tier. Confirming eligibility first avoids wasting a hard credit inquiry on an application that was never going to be approved.
4. Weigh benefits you'll actually use
Lounge access, insurance covers, and fuel surcharge waivers only add value if they match your life — count them, but don't let a long benefits list distract from the reward-rate-minus-fee math above for a card you'd otherwise skip.
