Cashback Calculator
Calculate your cashback reward, effective purchase cost, monthly cashback, and estimated annual reward in seconds.
Cashback = Purchase Amount × Cashback Rate ÷ 100
Effective Cost:
Effective Cost = Purchase Amount − Total Reward
How to Calculate Cashback (Step by Step)
Cashback is a small part of your money that comes back to you after you buy something. To find out how much you will get, you only need two numbers: how much you spent, and the cashback percentage.
Example: You buy something for $500 and your card gives 5% cashback. So $500 × 5 ÷ 100 = $25. Your real cost is $500 − $25 = $475.
It works the same in any currency. If you spend 7,600 and get 10% cashback, you get 7,600 × 10 ÷ 100 = 760.
Quick Cashback Table
| You Spend | 1% Cashback | 2% Cashback | 5% Cashback | 10% Cashback |
|---|---|---|---|---|
| 100 | 1 | 2 | 5 | 10 |
| 500 | 5 | 10 | 25 | 50 |
| 1,000 | 10 | 20 | 50 | 100 |
| 5,000 | 50 | 100 | 250 | 500 |
| 10,000 | 100 | 200 | 500 | 1,000 |
These numbers are in your own currency. Always read the offer’s rules too, because some offers have a maximum cashback limit.
How to Calculate Cashback Percentage
Sometimes you already know how much cashback you got, and you want to know the percentage. Divide the cashback by the amount you spent, then multiply by 100.
Example: You spent $200 and got $10 back. So $10 ÷ $200 × 100 = 5%.

Cashback vs Discount: What Is the Difference?
A discount makes the price lower right away, when you pay. Cashback is money that comes back to you after you have paid the full price, sometimes days or weeks later. That is why cashback offers often come with rules, like a maximum limit or a list of eligible shops.

Not all cashback cards work the same way. Card issuers generally use three different reward structures, and knowing which type you hold changes how you should calculate your expected reward.
| Card Type | How It Works | Typical Rate | Best For |
|---|---|---|---|
| Flat-rate | Same cashback percentage on every purchase, no categories to track. | 1.5% – 2% | Simplicity, predictable rewards |
| Rotating category | A higher rate on categories that change every quarter (e.g. groceries, gas, dining), often after activation. | 5% on activated categories, 1% elsewhere | Shoppers who track and activate categories |
| Fixed tiered | Set higher rates on specific categories like dining and travel year-round. | 2%–4% on bonus categories, 1% elsewhere | Consistent spending in the same categories |
To estimate your real-world reward on a tiered or rotating card, calculate each category separately using the standard cashback formula, then add the results together. For example, if you spend $300 on groceries at 5% and $700 on everything else at 1%:
Your blended effective cashback rate on the full $1,000 spent would be 2.2%, even though the advertised headline rate was 5%. This is why the “effective cashback rate” figure from the calculator above is more useful for comparing offers than the advertised percentage alone.
Cashback vs Points vs Miles
Cashback is only one type of reward. Points and travel miles are the other two common formats, and comparing them requires converting everything to a common unit – typically an estimated cents-per-point value.
| Reward Type | Typical Value | Flexibility | Best For |
|---|---|---|---|
| Cashback | Fixed, 1 point = 1 cent (typically) | Highest – usable anywhere | Simplicity and guaranteed value |
| Points | Variable, often 1–2 cents per point | Medium – gift cards, statement credit, travel | Flexible redemption options |
| Airline miles | Variable, can exceed 2 cents per mile with premium redemptions | Low – mainly travel | Frequent flyers who redeem for premium cabins |
If you are unsure which is better for you, calculate the cashback equivalent of a points or miles offer and compare it directly against a flat-rate cashback card using the calculator above.
Frequently Asked Questions
What is a Cashback Calculator?
A Cashback Calculator is an online tool that estimates the cashback reward from an eligible purchase using the purchase amount and cashback percentage.
How do I calculate cashback?
Multiply your purchase amount by the cashback percentage and divide the result by 100. For example, a $500 purchase with 5% cashback produces an estimated $25 reward.
How do I calculate cashback percentage?
Divide the cashback amount by the purchase amount and multiply the result by 100. This gives you the percentage rate of the cashback reward.
What is the difference between a cashback calculator and a cash back calculator?
Both terms generally refer to the same type of calculator. The tool calculates the estimated reward based on your purchase amount and cashback percentage.
What is the Cashback Calculator formula?
The basic formula is Cashback = Purchase Amount x Cashback Percentage / 100.
How much cashback can I get on a $1,000 purchase?
It depends on the cashback percentage and offer conditions. At 5% cashback, the basic calculation would be $50 before considering any maximum cashback limit.
What is a maximum cashback limit?
A maximum cashback limit is the highest reward an offer allows. If your calculated cashback exceeds the limit, the actual reward may be restricted to the stated maximum.
Is cashback the same as a discount?
No. A discount usually reduces the purchase price immediately, while cashback is generally received after an eligible transaction.
Can I calculate monthly cashback?
Yes. Enter your typical monthly spending and cashback percentage to estimate your monthly reward, then multiply by 12 for a yearly projection.
Does cashback apply to shipping and taxes?
Not necessarily. Each cashback program has its own rules, and some offers exclude taxes, shipping, fees, or other charges.
What is the difference between a flat-rate and a rotating category cashback card?
A flat-rate card pays the same percentage on every purchase. A rotating category card pays a higher percentage, often 5%, on categories that change every quarter and usually require activation, with a lower rate on everything else.
