How to Use

3. Press Calculate. The result shows the percentage amount, the increased value and the decreased value.

Worked Example

A jacket costs 200 and is reduced by 15%. 15% of 200 is 30, so the saving is 30. The jacket costs 170 after the discount, and it would cost 230 if the price rose by 15% instead.
