Calculate discounts, sale prices, and savings easily. Find the final price after a discount, calculate how much you'll save, and more.
The concept of discounting dates back to ancient marketplaces, but modern retail discounting began with department stores in the 19th century. JCPenney introduced the concept of "fair and square" pricing in 1902.
Studies show that consumers prefer getting something "extra" for free rather than an equivalent discount. For example, "Buy One Get One Free" is often perceived as more valuable than "50% off when you buy two."
When multiple discounts are applied, consecutive discounts (one after another) result in a greater total discount than if the percentages were simply added together. For example, two 20% consecutive discounts equals a 36% total discount, not 40%.
To quickly calculate a 10% discount, simply move the decimal point one place to the left. For 20%, double that amount. For 5%, halve the 10% amount. For example, 10% of $75 is $7.50, so 20% is $15 and 5% is $3.75.
