Frequently asked questions
Do 30% then 20% equal 50%?
No: successive 30% and 20% discounts give a real 44% reduction.
How do I calculate a sale price?
Final price = price × (1 − discount ÷ 100). 200 at 30% off = 140.

Apply the first discount, then the second on the new price; the tool does it automatically.
