How to Calculate Weight Loss Percentage in Excel

Using Excel, I can set up a straightforward formula to calculate the weight loss percentage. I will show you how to set this up quickly in your own workbook.

Key Takeaways:

• Use the formula =(Starting Weight – Current Weight) / Starting Weight * 100 provides an accurate weight loss percentage.
• Organize data with columns for “Starting Weight,” “Current Weight,” and “Weight Loss Percentage” to keep track of measurements.
• Formatting results as percentages with appropriate decimal points makes it easier to read.

Calculate Weight Loss Percentage in Excel

Setting Up the Spreadsheet

First, I start by creating a simple layout in Excel with columns for “Starting Weight,” “Current Weight,” and “Weight Loss Percentage.” Here’s how I set up the cells:

• Starting Weight is my initial weight at the start of my weight loss journey.
• Current Weight is my weight at a given point in time that I want to compare to my starting weight.
• Weight Loss Percentage will display the percentage of weight I’ve lost from my starting weight.

I typically enter these labels in cells A1, B1, and C1, respectively, and then begin entering data in the rows below.

Entering Starting and Current Weight

Next, I input my weights:

In cell A2, I enter my starting weight. For example, if I started at 180 pounds, I type 180 in cell A2.

In cell B2, I enter my current weight. Suppose I now weigh 170 pounds; I enter 170 in cell B2.

Applying the Weight Loss Percentage Formula

Now, I need to calculate the percentage of weight I’ve lost. Here’s the formula I use:

Weight Loss Percentage = (Starting Weight−Current Weight)/Starting Weight×100

STEP 1: Click on cell C2 (where I want the percentage to display).

STEP 2: Type in the formula:

=(A2 – B2) / A2 * 100

STEP 3: Press Enter.

This shows that I’ve lost 5.56% of my starting weight.

Formatting the Percentage

STEP 1: Go to the Home tab on the Excel ribbon. In the Number group, I click on the Percentage icon.

STEP 2: I may adjust the decimal points by clicking the Increase Decimal or Decrease Decimal icons to show the percentage to my preferred precision.
