Percentage & Discount Calculator

The first panel answers the classic question: what is X percent of Y. Type a percentage and a value and the answer appears instantly, which is useful for tips, commissions and quick shares of a total. The second panel measures change between two numbers and tells you whether it is an increase or a decrease, ideal for salary revisions, price rises and month-on-month growth.

The third panel handles shopping maths end to end. Enter the list price, the discount percentage and optionally a tax or GST rate, and you immediately see the amount saved, the price after discount, the tax added and the final amount payable. Every figure recalculates as you type, so you can compare offers side by side while standing in a shop.
