Frequently Asked Questions
How is the sale price calculated?
Sale price = original price × (1 − discount / 100). For example, a 20% discount on $80 gives a sale price of $64.
What is the effective discount percentage?
The effective discount percentage is the proportion of the original price you save. It equals (savings ÷ original price) × 100 and matches the discount you entered unless you override the sale price directly.
Can I calculate the original price from a sale price?
Yes — divide the sale price by (1 − discount / 100). For example, if the sale price is $64 and the discount is 20%, the original price is 64 ÷ 0.8 = $80.
