Calculating percentages is a fundamental task in data analysis and can help you understand the relative size or contribution of different values in a dataset. Google Sheets, a popular and widely-used spreadsheet program, provides various functions that make it easy to calculate percentages. This guide will provide a step-by-step explanation of how to use these functions to calculate percentages in Google Sheets, helping you to gain valuable insights from your data.
Why Learn How to Calculate Percentages in Google Sheets?
Calculating percentages is an essential skill for anyone working with data, whether you’re a student, a business professional, or a data analyst. With Google Sheets, you can quickly and easily calculate percentages to:
- Compare the size of different groups or categories
- Determine the proportion of a total
- Analyze changes over time
- Identify trends and patterns
Overview of Calculating Percentages in Google Sheets
This guide covers the following topics related to calculating percentages in Google Sheets:
1. Basic Percentage Calculation
Learn how to calculate the percentage of a value relative to a total using the % symbol and simple arithmetic operations.
2. Using the SUM Function
Discover how to use the SUM function to calculate the total of a range of cells, making it easier to find the percentage of a specific value within that range.
3. Using the COUNT Function
Understand how to use the COUNT function to count the number of cells in a range that meet specific criteria, allowing you to calculate percentages based on these counts.
4. Using the AVERAGE Function
Learn how to use the AVERAGE function to calculate the average value of a range of cells and then determine the percentage that a specific value represents within that average.
5. Conditional Percentage Calculation

How to Make Google Sheets Calculate Percentage
Google Sheets is a powerful tool for data analysis and calculation. One of the most common calculations that users need to perform is calculating percentages. In this article, we will discuss how to make Google Sheets calculate percentage with detailed steps and illustrative examples.
Understanding Percentage Calculation
Before we dive into the steps to calculate percentage in Google Sheets, it is important to understand what a percentage is. A percentage is a number that represents a fraction of 100. It is often used to express a proportion or a ratio of a part to a whole. For example, if a pizza is cut into 8 slices and you eat 2 slices, you have eaten 25% of the pizza.
Calculating Percentage of a Number
To calculate the percentage of a number in Google Sheets, you need to use the following formula:
% of a number = (part ÷ whole) × 100
For example, if you want to calculate the percentage of 15 out of 50, you would use the following formula:
= (15 ÷ 50) × 100
Here are the steps to calculate the percentage of a number in Google Sheets: (See Also: How To Assign A Color To A Value In Google Sheets)
- Enter the whole number in a cell.
- Enter the part number in another cell.
- Select the cell where you want the percentage to be displayed.
- Type = (part_cell ÷ whole_cell) × 100 and press Enter.
- Replace part_cell and whole_cell with the cell references that contain the part and whole numbers.
Calculating Percentage Change
To calculate the percentage change between two numbers in Google Sheets, you need to use the following formula:
% change = [(new_value – old_value) ÷ old_value] × 100
For example, if you want to calculate the percentage change between 25 and 35, you would use the following formula:
= [(35 – 25) ÷ 25] × 100
Here are the steps to calculate the percentage change in Google Sheets:
- Enter the old value in a cell.
- Enter the new value in another cell.
- Select the cell where you want the percentage change to be displayed.
- Type = [(new_value_cell – old_value_cell) ÷ old_value_cell] × 100 and press Enter.
- Replace new_value_cell and old_value_cell with the cell references that contain the new and old values.
Calculating Cumulative Percentage
To calculate the cumulative percentage of a data set in Google Sheets, you need to use the following formula:
= SUMIF(range, “<=current_cell", criteria_range) ÷ SUM(range)
For example, if you want to calculate the cumulative percentage of sales by region, you would use the following formula:
| Region | Sales | Cumulative % |
|---|---|---|
| North | 1000 | 1000 ÷ 5000 = 0.2 |
| South | 2000 | = SUMIF(B2:B3, “<=B3", A2:A3) ÷ SUM(B2:B3) = (1000 + 2000) ÷ 5000 = 0.6 |
| East | 1500 | = SUMIF(B2:B4, “<=B4", A2:A4) ÷ SUM(B2:B4) = (1000 + 2000 + 1500) ÷ 5000 = 0.9 |
| West | 500 | = SUMIF(B2:B5, “<=B5", A2:A5) ÷ SUM(B2:B5) = (1000 + 2000 + 1500 + 500) ÷ 5000 = 1 |
Here are the steps to calculate the cumulative percentage in Google Sheets:
- Enter the data set in two columns (e.g., region and sales).
- Select the cell where you want the cumulative percentage to be displayed.
- Type = SUMIF(range, “<=current_cell", criteria_range) ÷ SUM(range) and press Enter.
- Replace range with the column that contains the cumulative percentage values.
- Replace current_cell with the cell reference that contains the current cumulative percentage value.
- Replace criteria_range with the column that contains the data set values.
Recap
