Compare flat 2% vs category 5%

Use rough annual spend. The calculator assumes the category card earns 5% up to a cap, then a fallback rate on the remaining spend.

Flat 2% wins by $0

How to use / 使用方法

Start with real spend.

Use annual credit-card spend and isolate the portion that truly fits the 5% categories.

Apply caps and activation misses.

Enter the annual cap and a miss percentage for quarters you forget to activate or cannot use naturally.

Subtract fees and travel friction.

Annual fees and foreign transaction fees can erase rewards, especially if a card is not a travel card.

Verify issuer terms.

Check category calendars, merchant coding, exclusions, redemption minimums and APR before applying.

Official verification box / 官方验证盒

  • Confirm current reward rates, category calendars, activation deadlines, quarterly/annual caps and eligible merchants from the issuer’s official page.
  • Verify annual fee, foreign transaction fee, redemption minimums, welcome-offer eligibility, APR and balance-transfer terms before applying.
  • Merchant category coding can vary; do not assume every grocery, wholesale, PayPal, dining, gas or travel purchase qualifies.
  • Omellody is not a card issuer or financial advisor. Issuer terms and card agreements control.

Formula and interpretation

Flat card: total annual spend × flat reward rate − annual fee. Category card: eligible active category spend up to cap × category rate + remaining spend × fallback rate − annual fee − estimated foreign transaction fee.

FAQ

Is 5% cash back always better than 2%?
No. Caps, activation rules, eligible categories, fallback rates, annual fees and unused categories can make a simple 2% card better.
Does this use current issuer category calendars?
No. Enter the current categories and caps after verifying them on the issuer’s official site. This tool does not fetch live offer data.
Should I include a welcome bonus?
Use this calculator for ongoing rewards. If a welcome offer matters, verify official terms and use a separate signup-bonus or annual-fee calculator.
Is this credit-card advice?
No. It is educational math support, not personalized credit, financial, tax or legal advice. Avoid carrying balances for rewards.
