How to use the Discount Calculator
- Enter the original price and the discount percentage.
- Add a second discount or sales tax if needed.
- Read the final price and how much you save.
Final price = price × (1 − d₁ ÷ 100) × (1 − d₂ ÷ 100). Stacked discounts are applied one after the other, so 20% + 10% is a 28% total discount, not 30%. Tax, if entered, is added after discounts.
Frequently asked questions
Are two discounts the same as adding them together?
No. The second discount applies to the already reduced price, so the combined discount is smaller than the sum.
