Interest on a card purchase can exceed its reward.
One fictional purchase
A fictional $1,000 U.S. consumer credit-card purchase earns a usable one-time 2% reward: $20. Assume 24% APR, no purchase grace period, a 365-day divisor and no payments or compounding during this simplified illustration. No fees or other transactions.
For 30 days, $1,000 × 0.24 ÷ 365 × 30 gives about $19.73 interest. Reward less interest is $0.27. For 45 days, interest is about $29.59, exceeding the reward by $9.59. Scenarios are separate. Round only final dollar results. This is not a profit calculation.
The CFPB explains that many issuers calculate interest daily. Actual terms and payments change results. Do not miss required payments.
