## How to calculate 15 percent of an amount

If you are interested in learning more and you want to learn more about how to calculate the 15% of a quantityWe are going to explain how to do it.

For calculate the percentage of a number always te have to apply a rule of three very simple. In this case, below you have represented how it would look like to get the 15% from a number:

If you notice, we have two unknowns in the formula:

• B is the amount or number from which you want to get your 15 percent.
• And it is the result you are looking for, i.e., the 15% of the number

In short, if you are going to calculate 15 percent of an amount you have to apply the following mathematical formula:

Y = quantity x 15 / 100 = quantity x 0.15

In the end, to get the percentage of any number we only have to apply a simple multiplication that you can easily solve with any calculator.

Here is an example of the theory we have just seen by calculating 15 percent of 100, an operation that can be done from memory

### 15 percent of 100

Based on the theory seen in the previous point, we are going to calculate the 15% of 100 applying the mathematical formula:

Y = amount x 0.15 = 100 x 0.15 = 15

In this case it is very easy since multiplying by 100 implies moving the decimal point two positions to the right so there is no need to use the calculator.

## Calculate 15% in Excel

If you want to use Excel to extract 15% of a number, the Microsoft program also makes the calculation immediately with a simple formula that you must type in an empty cell:

=cell*15%

Cuando ponemos 'celda' debes tener en cuenta que hay dos posibles escenarios:

• You have written the amount from which you want to get its 15% in Excel in an empty cell, so you must write its coordinates. (Ex: =A1*15%)
• You have written the number directly in the formula itself (e.g. =100*15%).

In either case, both methods are valid for calculate 15 percent in Excel.
