Frequently asked questions
- How do I calculate a discount percentage?
- Divide the amount you save by the original price, then multiply by 100. For example, saving 25 on a 100 item is a 25% discount.
- What if I have a stacked discount?
- Apply them sequentially, not additively. A 20% off then 10% off is not 30% off — it's 28% off (100 → 80 → 72).
- Can I use this to find the original price from the sale price?
- Yes — enter the original price field as the unknown and work backwards, or rearrange: original = final ÷ (1 − discount/100).
