How to Calculate Percentage in Google Sheet?

Calculating percentages in Google Sheets can be simple and straightforward.

Whether you’re working on a personal budget, school project, or business report, knowing how to calculate percentages can make your data more meaningful.

This guide will walk you through the process step-by-step, using plain language and practical examples.

Basics of Percentage Calculation

Before diving into Google Sheets, let’s review the basics of percentage calculations. A percentage represents a number or ratio as a fraction of 100. The formula for calculating a percentage is:

[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]

For example, if you have 20 apples out of 50 apples, the percentage is:

[ \left( \frac{20}{50} \right) \times 100 = 40% ]

Setting Up Google Sheets

To start, open Google Sheets and create a new spreadsheet or open an existing one.

Step-by-Step Instructions

• Input Your Data: Enter your data into the cells. For instance, let’s say you have the following data:
  • Column A: Names of studentsColumn B: Scores obtainedColumn C: Total possible scores
  | A | B | C | |-------|---------|-------| | Name | Score | Total | | John | 45 | 50 | | Jane | 38 | 50 | | Bob | 42 | 50 |

• Calculate the Percentage:
  • Click on cell D2 (assuming you want to calculate the percentage for John first).
  • Enter the formula: =B2/C2*100
  • Press Enter. The result should display 90 in cell D2, which means John scored 90%.

• Apply the Formula to Other Cells:
  • Click on the cell D2 where you entered the formula.
  • Hover over the bottom-right corner of the cell until you see a small square (fill handle).
  • Click and drag the fill handle down to apply the formula to other cells (D3 and D4).

Your updated table should look like this:

|   A   |    B    |   C   |    D    |
|-------|---------|-------|---------|
| Name  | Score   | Total | Percent |
| John  |   45    |  50   |   90%   |
| Jane  |   38    |  50   |   76%   |
| Bob   |   42    |  50   |   84%   |

Formatting Percentages

Google Sheets allows you to format numbers as percentages easily:

1. Select the cells that contain your percentage calculations (D2 to D4 in this example).
2. Click on the “Format” menu at the top.
3. Select “Number”.
4. Choose “Percent”.

This will format the numbers as percentages, making your data more readable.

Practical Examples

Example 1: Budget Tracking

Suppose you want to track your monthly expenses and calculate what percentage of your income each expense represents. Here’s how you can do it:

• Set Up Your Data: | A | B | |--------------|------------| | Expense Type | Amount ($) | | Rent | 1200 | | Food | 600 | | Utilities | 150 |
• Add Total Income:
  • Set cell B5 to your total income, e.g., 4000.

• Calculate Percentages:
  • In cell C2, enter =B2/$B$5*100 to calculate the percentage for rent.
  • Drag the fill handle down to apply the formula to other cells (C3 and C4).

• Format as Percentages:
  • Select cells C2 to C4.
  • Format them as percentages using the steps mentioned above.

Your table should look like this:

|      A       |     B      |     C     |
|--------------|------------|-----------|
| Expense Type | Amount ($) | Percent % |
| Rent         | 1200       |   30%     |
| Food         | 600        |   15%     |
| Utilities    | 150        |  3.75%    |

Example 2: Exam Scores

You can also use percentage calculations for exam scores:

1. Input Data:| Student Name | Score Obtained | Total Possible Score |
2. Use Formula:
   • Use =B2/C2*100 for each student.
3. Format:
   • Format the results as percentages.
