Discount calculator

Price after the discount, stacked discounts done right, and what % off a sale really is.

Whether you are pricing a sale or checking one, the sums are quick but easy to get wrong. This gives the sale price, the saving, and the honest total when two discounts are stacked.

Why use it

Set sale prices with confidence and see exactly how much you are giving away.
Stack two discounts correctly: 20% off then 10% off is 28% off, not 30%.
Check a shop's "was and now" price to see what the discount really is.

How it works

Enter the original price.
Enter the percentage off, and an extra discount if there is a second one.
Or enter the sale price instead to find out what percentage off it is.
Read the sale price, the amount saved and the combined discount.

Good to know

Two discounts multiply, they do not add. 20% then 10% leaves you paying 0.8 times 0.9, which is 72% of the price: a 28% discount.
Prices ending in 9 or 99 are known as charm pricing. A sale that ends in a round number can feel more honest to some buyers.
For sellers: a 20% discount on an item with a 40% margin halves your profit on that sale. Check your margin before you shout "sale".

Questions

How do I work out a percentage discount?

Multiply the price by the percentage and divide by 100 to get the saving, then take that from the price. 25% off 8,000 is 2,000 off, so you pay 6,000.

Is 20% off and then another 10% off the same as 30% off?

No. The second discount comes off the reduced price, so you get 28% off in total. On 10,000 that is 7,200, not 7,000.

How do I find what percentage off a sale price is?

Take the sale price from the original, divide by the original and multiply by 100. From 15,000 down to 12,000 is 3,000 off, which is 20%.
