Discount percentage between two prices calculator
How to calculate it
Subtract the sale price from the original price, divide the saving by the original, and multiply by 100.
- Insert the values in the formula, perform the division first, and round only the final answer.
- The original price is the reference; the calculator also returns the cash saving.
Applied example
If a price falls from €100 to €80, the discount is 20% and the saving is €20.
Subtract the sale price from the original price, divide the saving by the original, and multiply by 100. The original price is the reference; the calculator also returns the cash saving.
Practical use

For discounts and sales, use “original price” as the reference. It must represent the full set or the starting point of the comparison.
Checks that matter
- Subtract the discount from the original price; do not add it.
- Do not swap the part and total; reversing them changes the meaning of the result.
- Keep full precision during the calculation and round only the final answer to match the accuracy of the source data.
