How to calculate a percentage increase

 To calculate a percentage increase, you can use the following formula:

Percentage Increase =

[(New Value - Old Value) / Old Value] x 100

Here's a step-by-step guide:

1. Determine the old value (the initial value or starting point).

1. Determine the new value (the final value or ending point).

1. Subtract the old value from the new value.

1. Divide the result from step 3 by the old value.

1. Multiply the result from step 4 by 100 to get the percentage increase.

For example, if the old value is 50 and the new value is 75:

Percentage Increase = [(75 - 50) / 50] x 100
Percentage Increase = (25 / 50) x 100
Percentage Increase = 0.5 x 100
Percentage Increase = 50%
So, the percentage increase from 50 to 75 is 50%.
