What is the Percentage Discount Calculator?
Find the percentage discount between an original and a sale price. To use the Percentage Discount Calculator, enter original price, sale price; it returns percentage discount, amount saved, and shows them instantly as you type.
Where the Percentage Discount Calculator fits
Find the percentage discount between an original and a sale price. The main figure it returns is the Percentage discount, worked out from the values you enter.
It belongs with the other sales, discounts & pricing tools. If you are comparing options or checking a result from another angle, try the Double Discount Calculator, Margin With Discount Calculator or the Markdown Calculator.
How to use the Percentage Discount Calculator
- Enter your numbers. The inputs are Original price ($), Sale price ($). Use real figures from your own records where you can. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Percentage discount, and the cards below show Amount saved. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Percentage Discount Calculator using the default values shown in the calculator above:
Inputs
| Original price ($) | 80 |
|---|---|
| Sale price ($) | 56 |
Results
| Percentage discount | 30% |
|---|---|
| Amount saved | $24.00 |
With these inputs the calculator returns Percentage discount: 30%. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Original price ($) from 80 to 96 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Percentage discount | 30% | 41.67% | +38.9% |
| Amount saved | $24.00 | $40.00 | +66.7% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
