Question 1

How do I calculate a discount?

Accepted Answer

Sale price = Original price x Discount rate. For example, if the original price is 100 and the discount is 20% off, the sale price = 100 x 0.8 = 80, saving 20.

Question 2

What is the difference between 80% and 20% off?

Accepted Answer

80% means the price is 80% of the original, which is a 20% reduction. 20% off also means a 20% reduction. They are two different ways of expressing the same thing.

Question 3

How do I calculate multi-item discounts?

Accepted Answer

For multi-item discounts, calculate the total price. For example, 'buy 2 get 1 half off' means the total for 3 items is 2.5 times the original price, so each item averages 83.3% of the original price. Use the multi-item comparison feature to quickly compare different discount plans.

Question 4

How do I reverse-calculate a discount?

Accepted Answer

Given the sale price and original price, the discount rate = Sale price / Original price. Savings percentage = (Original price - Sale price) / Original price x 100%. For example, an original price of 200 and sale price of 150 means a 75% rate (25% off).
