About the Credit Card Rewards Calculator
This credit card rewards calculator compares two cards side by side using your own spending. Enter how much you spend each month in bonus categories (such as groceries, dining or gas) and on everything else, then add each card’s earn rates, the value of a point, the annual fee and any sign-up bonus. The tool shows the rewards each card earns per year, what is left after the fee, and the total value over the number of years you expect to keep the card.
It is built for the most common question about premium cards: is the annual fee worth it? A card with a $95 or $250 fee only wins if its higher earn rates on your real spending beat a no-fee flat-rate card by more than the fee. The calculator also finds the monthly bonus-category spend at which the fee card starts to come out ahead.
Rates are entered as points (or percent cash back) per dollar, and point value in cents, so 1 cent per point means plain cash back. The sign-up bonus is counted once; fees and ongoing rewards repeat every year. Rewards are only worth it if you pay the balance in full — interest at typical card APRs wipes out any rewards quickly.
How to use the credit card rewards calculator
- 1Split your typical monthly card spending into bonus categories and everything else.
- 2Enter Card A’s earn rates, point value, annual fee and sign-up bonus.
- 3Enter the same details for Card B — often a no-fee flat-rate card.
- 4Set how many years you expect to keep the card.
- 5Compare the net values and check the break-even spend for the fee card.
Formula and method
Each card’s yearly rewards are your monthly spend in each bucket multiplied by the points (or percent) earned per dollar, times 12, converted to dollars with the point value in cents. Subtracting the annual fee gives the net value per year; adding the one-time sign-up bonus and multiplying by the years you plan to keep the card gives the total.
The break-even spend solves for the monthly bonus-category spend at which both cards have the same yearly net value, holding your other spend fixed. It ignores sign-up bonuses because those are one-off. The model assumes you pay in full every month and redeem points at the value you enter.

Worked examples
3% grocery card with $95 fee vs 1.5% no-fee card
Card A earns 12 × (800 × 3% + 1,200 × 1%) = $432 a year, or $337 after the $95 fee. The flat 1.5% card earns 12 × 2,000 × 1.5% = $360 with no fee. Over three years including the $200 bonuses, the no-fee card wins by $69 — the fee card needs about $928 a month of bonus spend to pull ahead.
Heavy grocery and dining spender
With $1,500 a month in bonus categories, Card A earns 12 × (1,500 × 3% + 800 × 1%) = $636, or $541 after the fee. The flat card earns $414. Over three years Card A is ahead by $381, so the $95 fee is easily worth it.
Premium travel card valued at 1.5¢ per point
Card A earns 12 × (1,200 × 4 + 1,000 × 1) = 69,600 points a year, worth $1,044 at 1.5¢ each, or $794 after the $250 fee. A 2% cash back card earns $528. Over three years plus the $750 welcome bonus, the travel card is ahead by $1,548 — but only if you really redeem at 1.5¢.
Frequently asked questions
Is a credit card annual fee worth it?+
It is worth it when the extra rewards you earn over a no-fee card, at your actual spending, exceed the fee. Compare the net yearly value of both cards; if the fee card only wins because of its sign-up bonus, consider downgrading after the first year.
How much is a credit card point worth?+
Cash back points are usually worth 1 cent. Airline and hotel points vary widely: transferable bank points are often redeemed at 1.25–2 cents, while statement credits or gift cards may give less than 1 cent. Use the value you realistically redeem at.
Is 2% cash back better than 3% in categories?+
Only if your category spend is small. A 3% category card beats a flat 2% card on the bonus spend but usually earns just 1% on everything else, so the flat card wins when most of your spending falls outside the bonus categories.
Are credit card rewards taxable?+
In the US, rewards earned from spending are generally treated as a rebate on purchases and are not taxable income. Bonuses paid without a spending requirement, such as for opening a bank account, may be reported as income.
Do rewards make sense if I carry a balance?+
Rarely. Paying 20%–30% APR on a balance costs far more than the 1%–5% you earn back in rewards. Pay the card in full each month, or focus on a low-rate or 0% balance transfer card while you pay the debt down.
