Calculate Percentage

How to calculate percentage?

To calculate a certain percentage of a number, follow these steps:

1. Divide the percentage by 100
2. Multiply the result by the number

Example: What is 25% of 56?

1. 25 / 100 = 0.25
2. 0.25 * 56 = 14

25% of 56 is equal to 14.

To calculate how much percent a number (A) is of another number (B), follow these steps:

1. Divide number (A) by number (B)
2. Multiply the result by 100

Example: What percentage is 14 of 56?

1. 14 / 56 = 0.25
2. 0.25 * 100 = 25%

14 is 25% of 56.

To calculate a percentage increase, follow these steps:

1. New value - Old value
2. Divide the result by the old value
3. Multiply the result by 100

Example: What is the percentage increase from 56 to 84?

1. 84 - 56 = 28
2. 28 / 56 = 0.5
3. 0.5 * 100 = 50%

The percentage increase from 56 to 84 is 50%.

If the result is negative, it means you have a percentage decrease.

To calculate a percentage decrease, follow these steps:

1. Old value - New value
2. Divide the result by the new value
3. Multiply the result by 100

Example: What is the percentage decrease from 84 to 56?

1. 56 - 84 = -28
2. -28 / 84 = -0.33
3. -0.33 * 100 = -33%

The percentage decrease from 84 to 56 is 33%.

If the result is positive, it means you have a percentage increase.
