Weight loss percentage calculator
Put weight change in context. See the percentage of your starting weight, plus reference weights for common milestones.
How this tool works
Percentage lost = (starting weight − current weight) ÷ starting weight × 100. Use the same unit for both weights. A negative result means weight gain.A worked example
Going from 200 lb to 180 lb is a 10% change. Going from 150 lb to 135 lb is also 10%, even though the number of pounds is different.Before you use the result
Reference weights are arithmetic checkpoints, not recommended goals. Unintentional weight loss deserves medical attention. This tool does not assess whether you should lose weight.Is percentage lost the same as body fat percentage?
No. This measures change in total body weight. It cannot separate fat, muscle, and water.Why show 5%?
CDC notes that modest weight loss can improve some health measures for adults above a healthy weight. Whether weight loss is appropriate is an individual decision.Sources
