Measure percentage change between an earlier and later office supply value.
The change between the original value and the new value is divided by the original value, then multiplied by 100.
For example, a value that rises from 80 to 100 has increased by 25%.
The result is a percentage. A higher or lower percentage has different meaning depending on the calculator, so compare it with the goal, limit, benchmark, or historical value relevant to your situation.
