How to Calculate Weight Loss Percentage

You probably have a goal weight in mind, but you may wonder how to calculate your progress. Here’s the equation for figuring out your weight loss percentage, the difference between your current weight and your original weight divided by the original weight multiplied by 100%. This is also known as a person’s BMI (body mass index). Using this formula will help you keep track of if you’re getting closer to or farther away from reaching that goal.

What is weight loss percentage

Weight loss percentage calculates how much you have lost since you started. It is a percentage and not a weight in pounds or kilograms, which makes it easier to calculate. The easiest way to calculate your weight loss percentage is to divide the difference between your current weight and your original weight by your original weight multiplied by 100%.

Let’s use an example. Fred is 215 pounds, and he wants to lose weight. He starts by eating healthy and doing workouts at the gym. After 3 months, he has lost 10 pounds because of his alternative lifestyle, so now his weight is 205 pounds. How much did Fred lose, exactly? Well, you can quickly calculate that by dividing the difference between his current weight (205) and his original weight (215) by 215 multiplied by 100%. So .0833 x 215 = 17.90 or just 18%. Fred lost 19% of his original weight in 3 months, knowing that it would take more than a couple of years to reach his target goal weight, which would be around 150-160 pounds in this case.

Why it’s important to track your progress?

Tracking your progress is a great way to stay on track. It’s really easy to forget or slack off if you don’t know how much you’ve done so far. It can also help with motivation, and it’s much easier to achieve your goals if you know what they are. The progress tracker can also let you know when you have achieved specific milestones or rewards. If you’re concerned about weight gain, the tracker can be a great way to make sure that, so far, things are going as well as desired and that there is no need for concern.

What is successful weight management?

Successful weight management is achieved when the individual’s target goal is reached. This may be a number on a scale, or it could be their target clothing size. Successful weight management also means keeping to your diet plan and taking great care of yourself in order to maintain an active lifestyle where you can continue to enjoy life without feeling guilty about every morsel that passes your lips.


Calculating weight loss percentage is a great way to track your progress and stay motivated.
