## Introduction

In order to calculate percent loss of weight, you need to know the initial and final weight of the object or person. The formula to calculate percent loss of weight is:

((initial weight – final weight)/initial weight) x 100 = percent loss of weight

For example, let’s say that you start a diet and your initial weight is 200 pounds. After one month on the diet, you weigh 175 pounds. To calculate your percent loss of weight, you would use the following formula:

((200 – 175)/200) x 100 = 12.5%

This means that you have lost 12.5% of your body weight.

## The Formula

To calculate the percent loss of weight, you will need to use the following formula:

Percent Loss of Weight = (Initial weight – Final weight)/Initial weight

For example, if you weigh 200 pounds and lose 10 pounds, your percent loss of weight will be:

(200-10)/200 = 0.05 = 5%

You can also use this formula to calculate the percent gain of weight. For example, if you weigh 200 pounds and gain 10 pounds, your percent gain of weight will be:

(10/200) * 100 = 0.05 * 100 = 5%

## An Example

To calculate the percentage of weight loss, simply take the difference in weight (in pounds) and divide by the starting weight. Multiply that number by 100 to get a percentage. This method is most accurate when you weigh yourself nude or in light clothing on a set of scales that are properly calibrated.

For example, let’s say you started out at 200 pounds and you’ve lost 10 pounds. To calculate the percentage of weight loss, simply take the 10 pounds you’ve lost and divide it by 200. That gives you 0.05 (5%). To turn that into a percentage, simply multiply it by 100: 0.05 x 100 = 5%. So in this example, you’ve lost 5% of your body weight.

## Conclusion

To calculate percent loss of weight, divide the weight loss by the starting weight and multiply by 100. Percentages are often used to show how much something has changed compared to the original amount. Weight loss programs often use percent loss of weight as a way to measure progress. For example, a person might have lost 10 pounds (4.5 kg) out of a starting weight of 200 pounds (90.7 kg). To calculate percent loss of weight, divide 10 by 200 and multiply by 100, which gives you a 5 percent loss of weight.
