A discount reduces a price by a percentage of itself. To find the sale price you multiply the original by one minus the discount rate, which is the calculation this tool runs on every keystroke.
Knowing the saving in money rather than percent makes it easier to compare offers — a 40% discount on a small item can save far less than 15% off a large one.
There is nothing to submit or wait for — the result updates as soon as you change something.
