How to Calculate Weight Percentage Lost

You can determine the percentage of weight that you have lost.

According to Medline Plus, "Sixty-six percent of adults in the U.S. are overweight or obese." A prevalence of obesity has also led to a greater focus on weight loss. If you are one of the many individuals who has been working on achieving a healthier weight, you might want to figure the percentage of weight that you have already lost. You can determine this information by applying a simple mathematical formula.

1. Subtract your new current weight from your previous weight. For instance, if you used to weigh 200 pounds, but you now weigh 175, subtract 175 from 200 to get 25.

2. Divide your answer from step one by your original weight. In this example, you would divide 25 by 200 to get 0.125.

3. Multiply the answer you found in step two by 100 to calculate the weight percent lost. For instance, you would multiply 0.125 by 100 to get a weight loss percentage of 12.5%.
