How to calculate
Find the sale price and your savings.
Saving = price × discount ÷ 100; sale price = price − saving

Sale price: 90 ; You save: 30 .
Assumptions and limits
Tax is not included unless already part of the original price.

Understanding the result
The sale price is the original price after one percentage reduction. The savings amount is the difference between the two prices.
When this tool is useful
Check a sale label before tax or compare a percentage-off offer with a fixed saving.

Frequently asked questions
Can I add two discount percentages together?
Usually not. Sequential discounts apply to different bases: 20% off followed by 10% off gives 28% off overall, not 30%.
Does this add sales tax?
No. Apply the relevant tax separately to the appropriate taxable amount.
