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.
