About this tool
A percentage discount takes that share off the original price. A 20% discount on 100 leaves 80, so you save 20.
When a second discount is applied after the first, it comes off the already reduced price. So 20% off followed by 10% off is a total of 28% off, not 30%.
How it is calculated
Final price = original price × (1 − discount ÷ 100).
With two discounts: final = original × (1 − d1 ÷ 100) × (1 − d2 ÷ 100).
You save = original price − final price.
Worked examples
- 20% off 100: final 80.00, you save 20.00.
- 20% then 10% off 100: final 72.00, total discount 28.000000000000004%.
- 35% off 250: final 162.50.
Tips for better results
- Compare the final price, not just the percentage, when two offers differ.
- Check whether tax is added after the discount.
Frequently asked questions
How do I calculate a percentage discount?
Multiply the price by the discount percentage divided by 100 to get the saving, then subtract it from the price.
Is 20% plus 10% the same as 30% off?
No. The second discount applies to the reduced price, so the total is 28%.
