Determining % of Weight Loss

For the life of me, I could not figure out how to calculate the percentage so I googled it:

First of all you'll need to remember your initial weight. Secondly, you'll need your actual weight at this point. Now, the formula goes like this: ((IW-AW)/IW) * 100= weight loss percentage In this formula IW is your initial weight and AW is your actual weight at this point. It's not as complicated as it initially seems: practically all you do is subtract the actual weight from the initial weight and divide the number obtained by your initial weight. Multiply the result with 100 and you'll get the exact percent. To date I have lost 8.57%. Until next time...
