Percentage Change Between Two Numbers

The percentage change between two numbers depends on whether we are considering a reduction in value or an increase.

A reduction in value will always result in a higher percentage change than will an addition in value. That's because the higher the base, the lower the percentage for any given change.

For example: Reduction from 25 to 20 will result in a 20% reduction (25-20=5/25x100).
Whereas: Increase from 20 to 25 will result in a 25% increase (25-20=5/20x100).

Below input the 'start' number and the 'end' number and the result automatically emerges.
