### What It Does

The Weight Loss Percentage Calculator measures the change in your weight as a percentage rather than as a raw number. It allows you to compare your weight loss to others’ with a like to like comparison.

The Weight Loss Percentage Calculator gives you the option to compare weight loss between multiple users regardless of starting weight.

It gives you the option to create and share leader boards and determine who is “winning” when it comes to weight loss. It’s a great tool for competition, motivation and community and can be used for membership sites or group training.

### Why Weight Loss Percentage?

It seems counter intuitive that someone who has lost 50lb may not be the “biggest loser” when compared to someone who loses 20lb, but by using the Weight Loss Percentage Calculator, you can see the amount of weight a person is losing compared to their initial body weight.

It may be that the person who is losing 20lb doesn’t actually have 50lb to lose, and the person who has lost 50lb needs to lose 100lb more. By using the Weight Loss Percentage Calculator, you can compare where each person on their weight loss journey is, relative to their starting point.

Everyone, even those with only 5lb to lose, can compete, or just compare, on a level playing field.

### Weight Loss Percentage Formula

If you would like to work out the numbers behind the Weight Loss Percentage Calculator you can use the formula below. Be careful when you’re making comparisons to ensure that you’re comparing negative (weight loss) to negative results and positive (weight gain) to positive results.

Weight Loss Percentage = ((Current weight/Starting weight) - 1) * 100

• Negative answers indicates Weight loss
• Positive answers indicates Weight Gain

Harness enthusiasm and healthy competitive spirit by using the weight loss percentage calculator. It will help you on your weight loss journey and give you a quick and easy tool for group, community and competitive comparisons when weighing in.
