About the Cash Back Calculator

The Cash Back Calculator turns a credit card's reward rate into a real dollar figure so you can see exactly what a purchase or a month of spending earns you. You enter the amount you spent and the cash back percentage your card advertises, and it returns the reward you'll receive, usually credited as a statement credit, direct deposit, or gift card. It works for a single item, a category total, or your projected annual spending. Because the math is identical whether the figure is a sneaker purchase or a quarter of grocery bills, the tool is just as handy for comparing two cards as it is for double-checking a posted reward.

Reach for this calculator whenever a card quotes a rate and you want the number behind it. It is most useful when you are choosing between a flat-rate card and a tiered or rotating-category card, deciding whether an annual fee is worth paying off through rewards, or confirming that the cash back on your statement matches what was promised. Shoppers also use it before a large purchase, like an appliance or flight, to see whether putting it on a 3% card instead of a 1% card is worth the effort. Running a few quick scenarios takes seconds and prevents over-estimating what a rewards card actually pays.

Under the hood the formula is deliberately simple: cash back equals the purchase amount multiplied by the rate expressed as a decimal. A $75 purchase at 1.5% returns $75 times 0.015, or about $1.13; the same purchase at 3% returns $2.25. To work the other direction and find the rate you actually received, divide the reward by the amount spent and multiply by 100, so $30 earned on $1,000 spent is 3%. The calculator handles the decimal conversion for you, which is where manual math most often slips. For tiered cards, calculate each category separately, since a card may pay 5% on one type of spending and 1% on everything else.

Every calculation runs entirely in your browser, so the amounts and rates you type are never sent to a server, stored, or shared. The results are a precise reflection of the inputs you provide, but real-world earnings can differ for reasons the tool cannot see: many cards cap bonus rates after a spending threshold (often $1,500 per quarter on rotating cards, equal to about $75 back), some round rewards down, and a few exclude certain transactions. Treat the figure as an accurate reward estimate based on the advertised rate, and always confirm caps, exclusions, and current bonus categories in your card's terms before relying on it.

Frequently asked questions

How is cash back calculated?

Multiply your purchase amount by the cash back rate written as a decimal. For example, 2% on a $500 purchase is $500 x 0.02 = $10. The calculator converts the percentage to a decimal for you so you don't have to.

How do I find out what cash back percentage I actually earned?

Divide the reward you received by the amount you spent, then multiply by 100. If you got $30 back on $1,000 of spending, that's (30 / 1000) x 100 = 3%. This is useful for checking whether a card paid the rate it advertised.

Does the calculator account for spending caps or bonus category limits?

No. It applies the rate you enter to the full amount. Many rotating-category cards pay the bonus rate only up to a quarterly cap, such as $1,500 in spending, then drop to 1%. To model this, calculate the capped portion and the remainder separately.

How do I calculate cash back on a card with tiered or category rates?

Run a separate calculation for each category and add the results. If a card pays 5% on groceries and 1% on everything else, compute the 5% on your grocery total and the 1% on the rest, then total the two rewards.

Is cash back the same as a discount on my purchase?

Not exactly. Cash back is paid after the fact as a statement credit, deposit, or gift card, so you still pay the full price up front. It also only delivers real value if you pay your balance in full, since interest charges can quickly exceed any rewards earned.

How to Evaluate a Pay Raise: From Percentage to Real Take-Home

By the Super Simple Digital Tools Team · Updated June 2026

When a raise lands in your inbox it usually arrives as a single number, either a percentage or a new salary figure, and that lone number hides a lot. The first move is to translate it into the same units you actually spend money in. A 3% bump on $65,000 sounds modest, but it's $1,950 a year, about $162 a month, and roughly $0.94 more an hour. Seeing all four views at once is the difference between a vague 'okay' and a real decision, and it's exactly what a pay raise calculator is built to surface in a single step.

The second step is benchmarking. A raise only means something relative to two things: inflation and the market. With cost-of-living adjustments running around 2 to 3 percent and the 2026 Social Security COLA set at 2.8%, a raise below that range is effectively a pay cut in buying power. Average employer salary budgets for 2026 sit near 3.5%, so anything meaningfully under that may signal you're being undervalued. Use the calculator to express your raise as a clean percentage, then hold it up against these reference points before you celebrate or negotiate.

Third, separate gross from net. The headline number on your offer letter is pre-tax, and a raise can quietly push part of your income into a higher marginal bracket. Only the dollars above the threshold are taxed at the higher rate, so a raise never reduces your overall take-home, but it does mean you keep less of each new dollar than of your base pay. Federal income tax plus Social Security and Medicare alone trim 7.65% off the top before income tax even applies, so plan around the net figure, not the gross.

Fourth, think in compounding terms for anything long-running. Raises stack on top of each other, so the base you start from matters more than any single year's percentage. Two years of 4% beats one year of 5% followed by a flat year, because the second 4% is calculated on an already-higher number. If you're weighing a job change, calculate the new annual figure and project a couple of years forward; a higher starting salary often outruns a slightly bigger one-time percentage at your current employer.

Finally, use the numbers to negotiate concretely. Walking into a review saying 'I'd like more' is weak; saying 'a 6% increase would bring me to $68,900, which aligns with market data for this role' is specific and hard to dismiss. Run the figures first so you can name an exact target salary, an exact percentage, and what it means per paycheck. The calculator removes the mental math, leaving you free to focus on the case you're making rather than the arithmetic behind it.

  • Enter both your current and proposed salary to get the exact raise percentage, then compare it directly against the 2.8% COLA and the ~3.5% average employer budget for 2026.
  • Always read the per-paycheck number, not just the annual one. A $1,800 raise feels large until you see it's about $69 per biweekly check before tax.
  • Estimate your net by keeping roughly 65 to 80 percent of the gross raise, since FICA alone takes 7.65% before income tax is applied.
  • When comparing a salaried offer to an hourly one, divide annual pay by 2,080 to get a true apples-to-apples hourly rate before deciding.
