PERCENTAGE TRICK

To calculate a percentage, you need to know the total value and value you want to express as a percentage.

Formula for calculating a percentage

The formula for calculating a percentage is:

Percentage = (partial value / total value) x 100

Example

Suppose you want to calculate the percentage of a partial value of 25 with respect to a total value of 100.

Percentage = (25 /100) x 100 = 25%

How to calculate a percentage of increase or decrease

To calculate a increase in increase or decrease, you can use the following formula:

Increase percentage = (new value - old value) / old value) x 100

Decrease percentage = ((old value - new value) / old value) x 100

Example

Suppose you want to calculate the percentage of increase of a value that went from 100 to 120.

Increase percentage = ((120 - 100) / 100) x 100 = 20%

How to calculate a percentage of a total value

To calculate a percentage of a total value, you can use the following formula:

Partial value = (percentage / 100) x Total value

Example

Suppose you want to calculate the partial value that represents 25% of a total value of 1000.

Partial value = (25 /100) x 1000 = 250
