Weight loss percentage calculator
Turn a starting and current weight into your percentage lost and weekly pace.
Enter your starting and current weight to see the percentage. Add dates for your average weekly pace.
Weight-loss percentage is your total change divided by your starting weight. A steady pace of roughly 0.5 to 1% of body weight per week is the commonly cited healthy target, and GLP-1 trials reported their headline results as a percentage of body weight over many months. See realistic ranges in the weight loss calculator or read how much you can lose.
