Discount Percentage Calculator

Work out what percentage discount you are actually getting when a retailer advertises a dollar saving rather than a percentage off. Enter the original sticker price and the dollar amount you are saving (or have been told you will save), and the calculator returns the implied discount rate. Useful for comparing a "$20 off" deal against a "15% off" deal on differently priced items, for verifying that the discount you see at checkout matches what was advertised, and for spotting inflated "original price" claims that turn modest savings into impressive-sounding percentages.
