Understanding Percentages in Excel
Ready to explore Excel’s % world? It may be confusing, but no worries! We’ll define key terms like % and percent.
Then, we’ll learn the basic formula for calculating percentages in Excel. Mastering %’s in Excel is easy with this guide!
Defining key terms: percentage and percent
Percentage is a term used to show a portion of a certain quantity as a fraction of 100. It is represented with ‘%’. Percent means any value that can be turned into a percentage – like a decimal, fraction or ratio.
Here is a guide on how to understand percentage and percent:
 Describe what percentage is.
 Explain how to work it out with fractions and decimals.
 Introduce the ‘%’ symbol for percentages.
 Define percent as a value that can be expressed as a percentage.
 Show how percent values are converted into percentages.
 Give examples of percent values.
Knowing the difference between percentage and percent is important when using Excel. It recognises percentages by putting a ‘%’ at the end of the number. You can do this manually too by dividing the value by 100.
Percentages have been around for many years. Ancient people, such as Egyptians, used hieroglyphics to keep track of taxes. As trade and commerce developed, so did ways of calculating proportions and percentages.
The next step is understanding the formula for percentage calculation. We will look at this with examples that are easy to understand.
Understanding the basic formula for percentage calculation
 Here is a 5step guide to help understand basic percentage calculation.
 Step 1 – Choose two numbers. For example, the increase in sales figures from last year to this year.
 Step 2 – Identify which number is the whole or original amount (base). In our example, last year’s sales figures.
 Step 3 – Determine which number is the part or new amount (rate). This year’s sales figures.
 Step 4 – Subtract the original amount from the new amount.
 Step 5 – Divide the result by the original amount and multiply by 100 to get the answer.
Remember, Excel uses decimals instead of fractions or percentages. So be careful when rounding off the result. Also, label the base and rate for accuracy.
Now let’s move on to more complex percentage calculations in Excel.
Simple Percentage Calculations in Excel
I often use spreadsheets, so I know how important it is to know Excel. One helpful part of Excel is doing percentage calculations. In this section, I’ll teach you how to:
