How it works
When to use it
- Find the sale price after a discount.
- Work back to the original price from a sale price.
Formula
Sale price = original × (1 − discount %)Original = sale price ÷ (1 − discount %)Worked example
Given: $80 item, 25% off
- Sale price = 80 × 0.75 = $60.
- You save $20.
Result: $60, saving $20.
Reading the result
- Stacked discounts multiply: 20% off then 10% off is 28% off, not 30%.
Limitations

FAQ
How do I calculate 20% off?
Multiply the price by 0.8. For example, 20% off $50 is $50 × 0.8 = $40, saving $10.
How do I find the original price?
Original price = sale price ÷ (1 − discount). If an item costs $40 after 20% off, the original was $40 ÷ 0.8 = $50.
