Is a card with a higher cashback rate worth its annual fee? The answer depends on how much you spend each month. A 3% card can lose to a 2% card when spending is low.
The Cashback Calculator shows what a credit card really pays you in a year. Enter your monthly spending, the cashback rate, and the annual card fee. You get monthly rewards, gross yearly cashback, and net yearly earnings after the fee.

What the Calculator Does
The tool runs once on page load with sample numbers. Press the button after any change to refresh the three cards.
- Annual Net Earnings (After Fee): yearly cashback minus the card's annual fee.
- Monthly Rewards Earned: cashback from one month of spending.
- Gross Annual Cashback: twelve months of rewards before the fee.
- One flat rate: the same percent applies to all your spending.
How to Use It, Step by Step
- Enter your usual card spending in Monthly Spending ($). Use 0 or more, and the sample is $2,500.
- Enter the card's reward rate in Cashback Rate (%). Use 0 to 100, and the sample is 3.0.
- Enter the yearly fee in Annual Card Fee ($). Enter 0 for a no-fee card. The sample is $95.
- Press Calculate Rewards to see the results.
- Run it again with a second card's rate and fee to compare.
Only count spending you would make anyway. Extra purchases made just to earn rewards cost more than they return.
The Cashback Formula
The math has three short steps. Find the monthly reward, scale it to a year, then subtract the fee.
Monthly Spending × Rate×12-Annual Fee=Net Earnings
- Monthly Rewards = Monthly Spending × (Cashback Rate ÷ 100).
- Gross Annual Cashback = Monthly Rewards × 12.
- Annual Net Earnings = Gross Annual Cashback - Annual Card Fee.
Worked Example
Hannah puts about $1,800 a month on a card for groceries, gas, and bills. She is choosing between two example cards.
| Result | Card A: 2%, $0 Fee | Card B: 3%, $95 Fee |
|---|
| Monthly Rewards Earned | $36.00 | $54.00 |
| Gross Annual Cashback | $432.00 | $648.00 |
| Annual Net Earnings (After Fee) | $432.00 | $553.00 |
Card B wins by $121.00 a year at Hannah's spending level. Card A's math is $1,800 × 0.02 × 12 = $432.00.
Now picture her brother Leo, who spends only $200 a month. A 1.5% card with a $95 fee earns him $36.00 gross. His net result is -$59.00, so the card costs him money.
How to Read the Results
Annual Net Earnings (After Fee) is the number to compare between cards. A negative value means the fee is larger than your rewards.
Monthly Rewards Earned shows the steady trickle you can expect on your statement. It helps you see rewards as part of your monthly budget.
Gross Annual Cashback is the total before the fee. The gap between gross and net shows how much the fee takes.
Getting More From Cashback Cards
A quick break-even check helps: divide the fee by the extra reward rate. For Card B, $95 ÷ 1% = $9,500 a year, or about $792 a month. Spend more than that and the fee card pays off.
Tiered cards pay different rates on different purchases. Say you earn 3% on $600 of groceries and 1% on $1,200 of other spending.
That is $18 plus $12, or $30 a month. Divide $30 by $1,800 to get a blended rate of about 1.67%, then enter that.
Cashback only helps if you pay in full each month, since card interest usually wipes out rewards fast. If you carry a balance, the credit card payoff calculator shows how to clear it. High balances can also hurt your score, which the credit utilization calculator helps you track.
Some stores offer an upfront discount instead of cashback. The cashback vs discount calculator compares both.

Limitations and Assumptions
- One flat rate covers all spending. Bonus categories, rotating rates, and spending caps are not modeled.
- Sign-up bonuses, points values, and redemption rules are not included.
- Spending is assumed to be the same every month.
- Interest charges are ignored. The results assume you pay the full balance each month.
- A blank box, a negative spend or fee, or a rate above 100% shows a message and N/A.
- Spending of 0 still runs, so the net line simply shows minus the fee, such as -$95.00.
FAQs About the Cashback Calculator
How is cashback calculated?
Multiply your spending by the cashback rate. At 2%, every $100 you spend earns $2.00 back.
Is an annual fee card ever worth it?
Yes, when your extra rewards beat the fee. Run both cards in the tool and compare the net earnings line.
Why is my net earnings result negative?
Your yearly rewards are smaller than the annual fee. A no-fee card would likely serve you better at that spending level.
Does the calculator handle bonus categories?
No. It uses one rate for all spending. For a tiered card, enter a blended rate that reflects your usual mix.
Is cashback taxable?
Card rewards earned on purchases are generally treated as a rebate, not income. Bonuses paid without spending may differ, so check with a tax professional.
How do I compare two cashback cards?
Run the tool once for each card with the same monthly spending. The card with the higher Annual Net Earnings pays you more.
