About Discounts

Discounts are one of the most common calculations in everyday shopping. A simple percentage discount reduces the original price by that fraction — for example, 25% off a $80 item saves you $20, giving a final price of $60. Things get more interesting with stacked (double) discounts: if a store offers 50% off and then an extra 20% off the sale price, the second discount applies to the already-reduced price, not the original. So you pay 80% of 50%, which is 40% of the original — a total effective discount of 60%, not 70%. This calculator handles both single and double discounts so you always know exactly what you will pay.

FAQ

How do I calculate a discount manually?
Multiply the original price by the discount percentage divided by 100. For example, 25% off $80: $80 x 0.25 = $20 savings. The final price is $80 - $20 = $60.
What is a double (stacked) discount?
A stacked discount applies a second percentage reduction on top of the first. The second discount is calculated on the already-reduced price, not the original. For example, 30% off then 10% off: the item is first reduced by 30%, and then the sale price is reduced by another 10%.
Does 50% + 20% off equal 70% off?
No. A 50% discount followed by a 20% discount does not equal 70% off. After 50% off, you pay half. Then 20% off that half means you pay 80% of 50% = 40% of the original price. The effective total discount is 60%, not 70%.
How do I find the original price from a sale price?
Divide the sale price by (1 - discount/100). For example, if an item costs $60 after a 25% discount: $60 / (1 - 0.25) = $60 / 0.75 = $80 original price.
