Percentages are a way of expressing a proportion or ratio as a fraction of 100. They're incredibly versatile and used in countless scenarios. Here are just a few examples:
The core formula for calculating a percentage is:
(Part / Whole) x 100 = Percentage
Let's break this down:
In this case, the "Part" is unknown (what we're trying to find), and the "Whole" is 50. We know the "Percentage" is 20%.
(X / 50) x 100 = 20
Solving for X:
X = (20 / 100) x 50
X = 0.20 x 50
X = 10
Therefore, 20% of 50 is 10.
A common calculation is determining the percentage change between two numbers. This is useful for tracking growth or decline over time. The formula is:
((New Value - Old Value) / Old Value) x 100 = Percentage Change
Let's say your sales were $10,000 last month and $12,000 this month. To calculate the percentage increase:
((12,000 - 10,000) / 10,000) x 100 = Percentage Change
(2,000 / 10,000) x 100 = Percentage Change
0.20 x 100 = Percentage Change
Percentage Change = 20%
This means your sales increased by 20%.
Sometimes you need to convert a decimal or fraction to a percentage, or vice versa.
To convert a decimal to a percentage, simply multiply the decimal by 100.
Example: 0.75 x 100 = 75%
To convert a fraction to a percentage, divide the numerator by the denominator and then multiply by 100.
Example: 1/4 = (1 / 4) x 100 = 0.25 x 100 = 25%
To convert a percentage to a number, divide the percentage by 100.
Example: 30% = 30 / 100 = 0.30
Spreadsheets like Google Sheets and Excel offer powerful functions for calculating percentages. Here are a few common formulas:
To calculate the percentage of a value within a total, use the following formula:
=(Value / Total)
100
For example, if "Value" is in cell B2 and "Total" is in cell B3, the formula would be =(B2/B3). You can then format the cell as a percentage.
100
Google Sheets has a built-in PERCENT function, although it's less commonly used for basic percentage calculations. The more common approach is the formula above. You can also use the FORMAT cell as percentage option.
Excel uses the same basic formulas as Google Sheets. The syntax is identical: =(Value / Total) . Excel also allows you to format cells as percentages.

Beyond the basics, here are a few more advanced scenarios:
This is essentially the same as finding a percentage of a number, using the formula (Part / Whole) x 100.
Again, this refers to the basic percentage formula: (Part / Whole) x 100.
To add a percentage to a number, first convert the percentage to a decimal (divide by 100), then multiply the decimal by the number and add the result to the original number.
Example: Add 10% to 100.
10% = 0.10
0.10
100 = 10
100 + 10 = 110
