Using BF % to Determine Max Weight Loss

My gym is having a weight loss competition and I am debating entering. I don’t consider myself fat but like most people could probably stand to shed 10 lbs or so. I am going to get my bf tested tomorrow to see if it is even worth it to enter as the contest is based on percentage of weight lost. Does anyone know if there is an equation or a way to figure out how much fat weight you can possibly lose? I.E. If my body fat % is 15%, how much fat would I lose to get to 7% if my muscle weight remained the same? Thanks.

Nevermind, I figured it out. I feel like an idiot. Basic multiplication :slight_smile:
