Assumptions
- Assumes the flat reward rate you enter applies to all spend entered, with no caps or category exclusions.
- Does not account for milestone bonuses, welcome offers, or point-value redemption differences.
- Real cards often earn different rates per category — enter your card's blended or dominant rate for a rough estimate.
Formula Used
Annual reward = (monthly spend × 12) × reward rate; Net benefit = annual reward − annual fee
Applies one flat reward rate across your total monthly spend, then subtracts the annual fee to show what you would actually keep.
Example reward calculation
- Enter your monthly spend across each category.
- Enter the card's stated reward rate, e.g. 2%.
- Enter the card's annual fee.
- Review the estimated annual reward, fee, and net benefit.
Common Mistakes and Limitations
Common mistakes
- Treating an estimate as a guaranteed outcome.
- Ignoring fees, taxes, penalties, or changing rates.
- Using annual and monthly rates interchangeably.
- Forgetting that a calculator is only as reliable as the inputs entered.
Limitations
- Does not model caps, exclusions, or milestone rewards — see the card's own detail page for those.
- Point-based rewards with no stated rupee value cannot be estimated here.

What is a credit card rewards calculator?
A credit card rewards calculator estimates a card's estimated annual reward value from the inputs you provide. It shows the formula and the assumptions so you can check the working, rather than predicting a guaranteed outcome.
Are the results guaranteed?
No. The results are estimates based on the stated formula, your input values, and the assumptions listed on this page. Interest rates, tax rules, market returns, and inflation all change.
Why is my real card's reward lower than this estimate?
Most cards cap reward value on some categories, exclude others entirely (rent, fuel, utilities, wallet loads, and EMI conversions are common exclusions), and some rewards are catalogue points with no fixed rupee value. Check the card's own page for its exact rules.
