How to Calculate Percentage Increase

Percentage increase represents the rate of growth from an old value to a new value. It is widely used in finance, stock market analysis, and sales tracking to measure growth.

The Percentage Increase Formula

Percentage Increase = ((New Value - Old Value) / Old Value) × 100

Step-by-Step Calculation

  1. Subtract the old value from the new value to find the increase amount.
  2. Divide the increase amount by the old (original) value.
  3. Multiply the result by 100 to convert it to a percentage.

For example, if a price increases from $100 to $125: the difference is 125 - 100 = 25. Divide 25 by 100 to get 0.25. Multiply by 100 to get a 25% increase.
