Finding Discount Percentage

An item originally $200 is now $140: ($200 - $140) / $200 x 100 = 30% off. You save $60.

Frequently Asked Questions

How do I find the original price if I know the sale price and discount?
Divide the sale price by (1 - discount/100). For example, $75 at 25% off means the original was $75 / 0.75 = $100.
What is the difference between percent off and dollars off?
Percent off is relative to the original price (e.g., 20% off $100 = $20 savings). Dollars off is an absolute amount (e.g., $20 off regardless of the price).
How do I compare two different discounts?
Calculate the final price for each deal and compare. A 40% discount on a $50 item ($30 final) is less savings than a 20% discount on a $200 item ($160 final) in absolute terms, but more in relative terms.
