The percentage increase is calculated by finding the difference between the new value and the original value, dividing that difference by the original value, and then multiplying the result by 100 to convert it into a percentage. The formula is:
Percentage Increase=(New Value−Original ValueOriginal Value)×100\text{Percentage Increase}=\left(\frac{\text{New Value}-\text{Original Value}}{\text{Original Value}}\right)\times 100Percentage Increase=(Original ValueNew Value−Original Value)×100
Steps to calculate percentage increase:
- Subtract the original value from the new value to find the increase.
- Divide the increase by the original value.
- Multiply the result by 100 to express it as a percentage.
For example, if a stock price increases from $5 to $50:
- Increase = 50−5=4550-5=4550−5=45
- Divide increase by original value: 45/5=945/5=945/5=9
- Multiply by 100 to get percentage: 9×100=900%9\times 100=900%9×100=900%
So, the percentage increase is 900%.
