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
- Subtract the old value from the new value to find the increase amount.
- Divide the increase amount by the old (original) value.
- 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.
