How do you calculate percent achieved of a weight loss goal Example Start weight - 220 Goal weight - 180 Current weight 205 What percentage is you current weight to goal 180 goal being 100?

If you want to lose 40 pounds, then divide: 100/40=2.5 So 1 pound is 2.5% of your goal. For every pound you lose (under 220) multiply it by 2.5. EXAMPLES IF YOU NOW WEIGH-- 210 POUNDS YOU ARE 25% of the way to your goal. 205 POUNDS YOU ARE AT 37.5% 200 POUNDS YOU ARE AT 50% 190 POUNDS YOU ARE AT 75% If you wanted to calculate how much of your total body weight you've lost, then take your staring weight (220), subtract your current weight (220-205=15). Take that number and divide by your starting weight. (15/220=.068) In this case, you've lost 6.8% of your body weight and you want to lose 18.2% of your body weight.
