How Discount Calculations Work
A discount is calculated by multiplying the original price by the discount percentage, then subtracting that amount from the original price. For example, a 25% discount on a $150 item means you save $37.50, paying $112.50. To reverse-calculate the discount percentage, divide the savings by the original price and multiply by 100.
When stacking multiple discounts (e.g., 20% off plus an additional 10% off), the discounts are applied sequentially, not added together. A 20% discount followed by 10% off results in a 28% total discount, not 30%.
Frequently Asked Questions
How do I calculate a discount percentage from two prices?
Subtract the sale price from the original price to get the savings. Then divide the savings by the original price and multiply by 100. For example, if an item drops from $80 to $60, the savings is $20. Divide $20 by $80 to get 0.25, which is a 25% discount.
Do stacking discounts add up?
No. When you apply one discount after another, each discount applies to the already-reduced price. A 30% discount plus a 20% discount does not equal 50% off. Instead, you pay 70% of the original price, then 80% of that, which is 56% of the original price, for a total discount of 44%.
Is it better to get a flat dollar discount or a percentage discount?
It depends on the item price. A general rule of thumb: for items under $100, a dollar-off coupon tends to look and feel like a better deal; for items over $100, a percentage discount is often more impactful. Use this calculator to compare which option saves you more money in each case.
