Frequently Asked Questions
Multiply the original price by the discount percentage, then subtract from the original. Example: 25% off $120 = $120 × 0.25 = $30 savings, so the sale price is $90.
Subtract the sale price from the original price to get the savings amount, then divide by the original price and multiply by 100. Example: ($120−$90)/$120 × 100 = 25% off.
A double discount (or stacked discount) applies two percentage discounts sequentially, not additively. 20% off then 10% off is NOT 30% off — it's 28% off total. Use our discount calculator for each step.
