Understanding the Concept of Percentage in Excel
Calculating percentages is a common task in both business and personal settings and Excel offers several formulas to facilitate this process. In general, the percentage calculation is done by dividing the partial number by the total number and multiplying it by 100 to obtain the result in percentage form. Excel provides a wide range of formulas to calculate percentages, whether changes, increases, discounts, percentages of totals, among other areas.
To calculate percentages in Excel, we must first write the base figure in one cell and in the next cell, the value that represents the percentage of said base figure. Once this is done, we can use the Excel formula for percentage, which is = (percent cell / base figure cell) * 100. It is important to note that Excel automatically converts the result to percentage format, so it is not necessary to multiply by 100 in the formula. Below are some examples of how to apply this formula:
- Percentage of a total: = (B2/A2) * 100
- Percent increase or decrease: = ((B2-A2)/A2) * 100
- Percentage of a partial: = (B2/sum(A2:B2)) * 100
These percent formulas can be applied to both individual figures and ranges of cells. Depending on the case, it will be necessary to adjust the formula.
Detailed Steps to Calculate Percentage in Excel
The process of calculating the percentage in Excel is simple and useful for a variety of applications, whether for business, finance, academic research, among others. First of all, you must enter the numbers in the corresponding cells. For example, the total number could go in cell A1 and the partial number in cell B1. The main thing is the formula that you must write in the cell where you want the percentage to appear. The formula needed to calculate the percentage is simply the partial number divided by the total number, followed by multiplication by 100.
To illustrate this procedure, let's consider a practical example. If you have a class with 30 students, and 18 of them are women, we might want to know what percentage of the total class are women. In this case, you would put 30 in cell A1 (the total number) and 18 in cell B1 (the partial number). Next, to calculate the percentage you must write the following formula in cell C1: =B1/A1*100. After pressing enter, Excel will show you that 60% of the class is made up of women. Remember that although the number that Excel displays after calculating may have decimals, you can change the cell format to display the number as a percentage. This is done by selecting the cell, and then choosing the “Percent” cell format option from the Excel menu.
Ways to Apply Percentage in Real Situations Using Excel
The application of percentages in Excel has wide applications in real life. It is frequently used to calculate discounts, interest rates, price increases, among many other situations. Therefore, it is essential to understand how to calculate percentage in Excel. First, to calculate a simple percentage, you must divide the total number by 100 using the formula = (number / total) * 100. Then, place the formatted percentage to the desired cell. For example, if you have a total of 10 and you want to know what percentage 3 represents, you would simply put the formula “= (3/10) * 100” in the cell where you want the result.
On the other hand, the percentage increase calculation It is done using the formula = ((end value – start value) / start value) * 100. This formula is useful to know how much a value has increased or decreased compared to its original number. For example, if a product cost $100 and now costs $120, the formula to know the percentage increase would be "= ((120-100) / 100) * 100." This calculation would result in 20%, indicating that the product has suffered an increase of 20% compared to its original price.
In summary, with these formulas Excel can help you calculate:
- Simple percentages: = (number / total) * 100.
- Percentage increase: = ((final value – initial value) / initial value) * 100.
Common Errors When Calculating Percentage in Excel and How to Avoid Them
A common pitfall in Excel is incorrect use of the percentage function. Many people make the mistake of simply multiplying by the decimal value of the percentage. For example, to calculate 20% of 100, you might think of simply multiplying 100 by 0.20. But in reality, Excel will calculate this as '20', not '20%'. To avoid this error, you should always use the formula =A1*A2/100 to perform these percentage calculations.
You should always use the formula =A1*A2/100 to perform percentage calculations.
Another common error occurs when calculating the percentage of change. Many users try to subtract the start value from the end value and then divide it by the start value. But this will not always give the correct result. In fact, you should use the formula =(A2-A1)/A1 for this calculation in Excel.
To calculate the percentage of change, the formula =(A2-A1)/A1 must be used.
These are just two of the most common ways Excel users calculate percentages incorrectly. By familiarizing yourself with the correct formulas and being consistent in your application, you can avoid these errors and obtain the most accurate results.
