Frequently asked questions
How do I calculate a sale price from a discount percentage?
Multiply the original price by the discount percentage as a decimal to get the amount saved, then subtract that from the original price. For $80 at 25% off: $80 × 0.25 = $20 saved, for a sale price of $60.
How do I stack multiple discounts?
Apply each discount to the price remaining after the previous one, not to the original price - two 20% discounts stacked equal a 36% total discount, not 40%.
Is a 50% off then an additional 20% off the same as 70% off?
No - stacked discounts multiply, they don't add. 50% off leaves 50%, then another 20% off that leaves 40% of the original price, which is a 60% total discount, not 70%.
How do I calculate the percentage saved if I know the original and sale price?
Subtract the sale price from the original price, divide by the original price, then multiply by 100. A $50 item marked down to $35 saved you $15, and 15/50*100 = 30% off.
How do I find the discount percentage if I know both the original and sale price?
Subtract the sale price from the original price to get the savings amount, divide that by the original price, then multiply by 100. An item marked down from $120 to $90 saved $30, and 30/120 × 100 = 25% off.
Does a coupon for a fixed dollar amount work the same way as a percentage discount here?
Not directly - this calculator is built for percentage-off discounts. For a flat dollar-amount coupon (like $10 off), just subtract that fixed amount from the price yourself rather than entering it as a percentage, since a $10 coupon represents a different percentage off depending on the item's price.
Is 'percent off calculator' the same tool as a discount calculator?
Yes - both describe the same calculation: applying a percentage reduction to an original price to find the sale price and the amount saved, which is exactly what this tool does.
