Formula Explained
Sale Price = Original Price × (1 − Discount % / 100)
- Original Price
- = Pre-discount list price shown to the customer
- Discount %
- = Percentage off the original price (e.g. 25 for 25% off)
Worked example: A $200 jacket marked 25% off: discount = $200 × 0.25 = $50. Sale price = $200 − $50 = $150.
