To find the percentage increase, you calculate the change in value relative to the original value, expressed as a percentage. Here's how:
Steps to Calculate Percentage Increase
-
Calculate the Difference: Subtract the initial (original) value from the final (new) value.
Difference = Final Value - Initial Value
-
Divide by the Initial Value: Divide the difference you calculated in step 1 by the initial (original) value.
Ratio = Difference / Initial Value
-
Multiply by 100%: Multiply the result from step 2 by 100% to express the change as a percentage.
Percentage Increase = Ratio * 100%
Formula Summarized
The complete formula for percentage increase is:
Percentage Increase = [(Final Value - Initial Value) / Initial Value] * 100%
Example
Let's say the initial value is 50, and the final value is 75.
- Difference: 75 - 50 = 25
- Ratio: 25 / 50 = 0.5
- Percentage Increase: 0.5 * 100% = 50%
Therefore, the percentage increase is 50%.
Key Considerations
- A positive percentage indicates an increase.
- A negative percentage (if the final value is less than the initial value) indicates a percentage decrease.
In summary, finding the percentage increase involves determining the change between two values relative to the original value, expressed as a percentage, using the formula [(Final Value - Initial Value) / Initial Value] * 100%
