Microsoft Excel is a powerful tool that is used in almost every industry. From finance to marketing, the ability to work with data and calculate percentages is a valuable skill. In this blog post, we will explore how to master Excel percentage formulas and become an Excel expert.
Percentages as fractions or decimals:
To convert a percentage to a decimal or a fraction, you can use the following formulas:
Decimal: divide the percentage by 100. For example, to convert 25% to a decimal, divide 25 by 100: 25/100 = 0.25
Fraction: divide the percentage by 100 and format the result as a fraction. For example, to convert 25% to a fraction, divide 25 by 100 and format as a fraction: 25/100 formatted as a fraction is 1/4.
Increase or decrease a number by a percentage:
To calculate the new value after adding or subtracting a percentage from a number, use the following formulas:
Increase: multiply the original value by 1 plus the percentage. For example, to increase a value by 20%, multiply the original value by 1.2: = original value * 1.2
Decrease: multiply the original value by 1 minus the percentage. For example, to decrease a value by 20%, multiply the original value by 0.8: = original value * 0.8
Percentage change:
To calculate the percentage change between two numbers, use the following formula:
Percentage change: divide the difference between the two numbers by the original number, and then multiply by 100. For example, if the original number is 100 and the new number is 125, the percentage change would be: = ((125-100)/100)*100 = 25%
Formatting percentages:
You can format cells in Excel to display percentages. To do this, select the cells you want to format, right-click, and choose "Format Cells." In the Format Cells dialog box, select "Percentage" under the Number tab.
Calculating percentage of total:
To calculate the percentage of a total value, use the following formula:
Percentage of total: divide the value you want to calculate by the total value, and then multiply by 100. For example, if you want to calculate the percentage of sales for a particular product, divide the sales for that product by the total sales, and then multiply by 100.
In conclusion, mastering Excel percentage formulas is a valuable skill that can help you work with data and make informed decisions. By understanding these formulas and how to use them, you can become an Excel expert and increase your productivity and efficiency.
