What is Weight Loss Percentage?

Weight loss percentage is a measurement of how much body weight you have lost relative to your initial weight. Unlike simply tracking pounds or kilograms lost, the percentage gives a relative scale that is easy to understand and compare over time.

Why Percentage is Important

  • Motivation: Seeing progress in percentages can encourage continued effort.
  • Comparison: It allows for fair comparison between individuals of different body sizes.
  • Health Tracking: Helps assess whether weight loss is within a safe and healthy range.

Formula for Percentage of Weight Loss

The calculation of weight loss percentage is based on a simple formula:

Weight Loss Percentage (%) = [(Starting Weight − Current Weight) ÷ Starting Weight] × 100

Where:

  • Starting Weight = your initial weight before any weight loss
  • Current Weight = your weight at the current time

This formula provides a precise percentage of weight lost relative to your starting weight.


Example Calculation

Let’s calculate the weight loss percentage for a user:

  • Starting Weight: 90 kg
  • Current Weight: 78 kg

Step 1: Subtract current weight from starting weight:

90 − 78 = 12 kg

Step 2: Divide by starting weight:

12 ÷ 90 = 0.1333

Step 3: Multiply by 100 to get percentage:

0.1333 × 100 ≈ 13.33%

So, the user has lost approximately 13.33% of their body weight.
