Calculating your Body Mass Index (BMI) in Excel can be a game-changer for anyone looking to keep track of their health.

It’s incredibly easy to do using Excel! 📊
In this guide, we’ll walk you through a step-by-step tutorial on how to create a simple formula to calculate your BMI in Excel. Plus, we’ll share some helpful tips, common mistakes to avoid, and troubleshooting advice to ensure everything runs smoothly. Let’s dive in!
What is BMI?
BMI is a number calculated from a person's weight and height. It's defined as the individual's body mass divided by the square of their height. The resulting number can help categorize individuals into different weight categories:
- Underweight: BMI < 18.5
- Normal weight: BMI 18.5–24.9
- Overweight: BMI 25–29.9
- Obesity: BMI ≥ 30
How to Calculate BMI in Excel
Step 1: Open Excel and Set Up Your Worksheet
Start by opening a new Excel workbook. In your worksheet, create headers in the first row to keep your data organized.
- A1: "Weight (kg)"
- B1: "Height (m)"
- C1: "BMI"
Step 2: Input Your Data
In the next rows, enter the weights and heights for the individuals whose BMI you want to calculate. Here’s an example of how your worksheet may look:
<table> <tr> <th>Weight (kg)</th> <th>Height (m)</th> <th>BMI</th> </tr> <tr> <td>70</td> <td>1.75</td> <td></td> </tr> <tr> <td>85</td> <td>1.80</td> <td></td> </tr> </table>
Step 3: Enter the BMI Formula
Now, it’s time to calculate the BMI. Click on cell C2 (the first cell under the BMI header) and enter the following formula:
=A2/(B2^2)
This formula divides the weight by the square of the height, which gives you the BMI value. Once you’ve entered the formula, hit Enter.
Step 4: Copy the Formula
To calculate BMI for additional individuals, simply drag the fill handle (a small square at the bottom-right corner of the cell) down to copy the formula to the cells below. Excel will automatically adjust the cell references accordingly.
Step 5: Format Your BMI Results
For better readability, you might want to format the BMI results. Select the BMI cells, right-click, choose Format Cells, and select Number with 1 or 2 decimal places. This will give your results a neater appearance.
Understanding the Result
Once you have calculated the BMI, you can interpret the results based on the classification mentioned earlier. This allows you to quickly understand if someone is underweight, at a healthy weight, overweight, or obese based on their BMI number.
Common Mistakes to Avoid
While calculating BMI in Excel is straightforward, here are a few mistakes to avoid:
-
Incorrect Units: Ensure that you are using weight in kilograms and height in meters. Using pounds and inches will require converting them to the correct units, which can complicate the calculation.
-
Forgetting to Square the Height: A common mistake is not squaring the height in the formula. Double-check your formula to ensure it includes the exponent.
-
Entering Data Incorrectly: Always double-check the data entered in the weight and height columns for accuracy.
Troubleshooting Issues
If your calculations don’t seem right, here are some troubleshooting tips:
-
Check Your Formula: Ensure you have entered the formula correctly without any typos. The correct formula should read
=A2/(B2^2)
. -
Review Data Input: Make sure the data in the weight and height columns are numbers and not text. You can spot issues by checking for any alignment inconsistencies.
-
Excel Settings: Occasionally, Excel might be set to a different regional format, which can affect decimal points. Check your regional settings if you notice unexpected results.
