Fitness Progress Calculator
Compare your starting and current body measurements and estimate progress toward your selected goal.
Calculation methodology
Weight change = current weight minus starting weight. Percentage weight change = weight change divided by starting weight, multiplied by 100. Average weekly change = weight change multiplied by 7, divided by elapsed days. Waist change = current waist minus starting waist. Goal progress = (current weight minus starting weight) divided by (target weight minus starting weight), multiplied by 100 for loss or gain goals.
Measurements may fluctuate due to hydration, timing, food intake and other factors. This calculator is for general tracking, not medical advice.
