How the Weight Loss Percentage Is Calculated
The formula for weight loss percentage is simple:
Weight loss percentage = (Weight lost ÷ Starting weight) × 100
For example, if you started at 200 lbs and now weigh 185 lbs, you’ve lost 15 lbs.
(15 ÷ 200) × 100 = 7.5% weight loss.
What Does My Weight Loss Percentage Mean?
Percentage lost helps you see progress in a way that’s easier to compare over time or between people of different sizes.
Common Ways People Use This Number
- Tracking progress in a medical or supervised weight loss program.
- Setting milestones such as “lose 5% of my starting weight.”
- Seeing long-term progress even when weekly changes are small.
Many programs consider a loss of around 5–10% of starting body weight to be a meaningful improvement in health markers for many people. The exact number that’s right for you depends on your health history, current weight, and goals.
