How it works

Percentage increase shows how much a value grew relative to where it started. Divide the difference by the original value, multiply by 100.

Formula: Percentage increase = ((New value - Original value) / Original value) x 100. For example, going from 100 to 150 gives ((150 - 100) / 100) x 100 = 50%.

Common uses: salary raises, price changes, population growth, investment returns. A negative result means the value actually fell.
