Frequently Asked Questions
How do I calculate a percentage discount?
Multiply the original price by the discount percentage divided by 100. For example a 25% discount on a $200 item is $200 times 0.25 which equals $50. Subtract this from the original price to get the sale price of $150. This calculator does this automatically for any price and discount combination.
How do I find the original price from a discounted price?
Divide the sale price by 1 minus the discount percentage divided by 100. For example if an item is on sale for $150 after a 25% discount the original price is $150 divided by 0.75 which equals $200. Use the Find Original Price tab in this calculator to do this instantly.
Is a 50% off sale better than buying one get one free?
Mathematically they are equivalent if you need two of the same item. Both result in paying 50 cents per dollar of original value. However buy one get one free requires you to take two items. If you only need one item 50% off is better value because you are not paying for something you do not need. For different items or if one item is more expensive than the other the calculations differ.
How do I calculate multiple discounts applied together?
Multiple discounts are not simply added together. A 20% discount followed by an additional 10% discount is not 30% off. First apply 20% to get 80% of the price then apply 10% to get 90% of that. So $100 becomes $80 then $72 which is a combined discount of 28% not 30%. This calculator handles single discounts — for stacked discounts apply each one separately.
What does percent off mean on a price tag?
Percent off means the discount is that percentage of the original price. A 30% off tag on a $50 item means you save $15 (30% of $50) and pay $35. Some stores show the sale price directly while others show the percentage reduction. This calculator helps you quickly verify whether a sale price matches the advertised percentage off.
