Start with the card you could keep for free
An annual-fee card should be compared with a realistic alternative, not with earning no rewards at all. Set your expected eligible monthly spending, the effective reward rate you can actually redeem, the annual fee, and a no-fee card's effective reward rate. Use the same spending for both.
Our calculator uses hypothetical flat cash-back rates. It does not model a specific issuer offer, category caps, points transfers, statement credits, welcome bonuses, or interest. It is a way to inspect one tradeoff before checking the full terms.
A $95 fee and a small reward-rate difference
Suppose normal eligible spending is $1,000 a month. A hypothetical 2% card earns $240 annually before its $95 fee, leaving $145. A hypothetical no-fee 1.5% card earns $180. The annual-fee card is $35 behind on these assumptions.
The additional reward rate is 0.5 percentage points, or 0.005 as a decimal. Dividing $95 by 0.005 gives $19,000 of annual eligible spending to break even. This is a comparison threshold, not a reason to increase spending.
If you carry a balance, change the question
The CFPB explains that a purchase grace period can let you avoid interest when its conditions are met and you pay in full by the due date. Carrying a balance can change that treatment. Read the card's own agreement rather than assuming every transaction has the same grace period.
If you expect interest charges, the reward-only result is incomplete. Compare borrowing costs and repayment options before treating rewards as a net benefit. The calculator makes no prediction about credit approval or score changes.
Value only what you would otherwise buy
Keep a separate note of benefits you cannot yet value. A blank value is more useful than a made-up saving.
- Count eligible spending you already expect, not spending induced by a bonus.
- Value a credit at the amount it would actually save you, with restrictions considered.
- Separate first-year bonuses from recurring years.
- If the fee card earns no more per dollar, there is no positive-spending break-even on rewards alone.
