Weight Loss Percentage Calculator
It is often a real challenge to lose weight. It can take a huge amount of effort and entail a great deal of commitment. You can use this calculator as an important tracking tool on your weight loss journey.
Total Weight Loss: 20 lbs
|#||Start Weight||Current Weight||Loss / Gain|
|1||220 lbs||99.79 kg||200 lbs||90.72 kg||-9.091%||-20 lbs|
How the Calculator Works
To calculate your weight loss percentage, your current weight is subtracted from the weight you were at when you first began your efforts to lose weight. This figure is then divided by your starting weight and the resulting number is multiplied by 100. This will give you your weight loss percentage. This formula can be presented as follows:
Weight Loss Percentage (%) = [ (Starting Weight − Current Weight) / Starting Weight ] × 100
If the calculator returns a positive figure, this shows that you have gained weight, while a negative figure shows that you have lost weight.
Let's take an example. You now weigh 180 pounds but began at 200 pounds. So, 180, your current weight, is subtracted from 200, your starting weight, resulting in 20. You've lost 20 pounds. The number 20 then needs to be divided by your starting weight, the result of which is 0.10. Finally, multiply 0.10 by 100 and you get 10. You have lost 10% of your starting weight.
Take another look:
Starting weight: 200 pounds
Current weight: 180 pounds
200 − 180 = 20
20 / 200 = 0.10
0.10 × 100 = 10%
What is Weight Loss Percentage Calculator
A weight loss percentage calculator is a tool used to determine the percentage of weight lost during a weight loss journey. It helps individuals track their progress and measure the effectiveness of their weight loss efforts. Here's how a weight loss percentage calculator typically works:
Input Variables: To calculate weight loss percentage, the calculator requires two main inputs: the starting weight and the current weight. These values are usually measured in pounds or kilograms.
Calculation Method: The weight loss percentage is calculated by taking the difference between the starting weight and the current weight, dividing it by the starting weight, and then multiplying by 100 to express the result as a percentage.
Weight Loss Percentage = ((Starting Weight - Current Weight) / Starting Weight) × 100
Interpretation: The calculated weight loss percentage indicates the proportion of weight lost relative to the starting weight. This percentage is often used as a motivational tool and benchmark to monitor progress throughout a weight loss journey.
For example, if someone started at 200 pounds and currently weighs 180 pounds, the weight loss calculation would be as follows:
Weight Loss Percentage = ((200 - 180) / 200) × 100 = (20 / 200) × 100 = 10%
This means that the person has lost 10% of their initial body weight.
It's important to note that weight loss percentage is just one metric to consider when evaluating progress. Other factors like body composition, health markers, and overall well-being should also be taken into account. Additionally, consulting with a healthcare professional or registered dietitian can provide personalized guidance and support for weight loss goals.
Weight Loss Percentage Calculator Example
Sure! Here's an example of using a weight loss percentage calculator to calculate the percentage of weight lost:
Assume the following information for an individual:
Starting weight: 200 lbs Current weight: 180 lbs
To calculate the weight loss percentage, we can use the following formula:
Weight Loss Percentage = ((Starting Weight - Current Weight) / Starting Weight) * 100
Using the given values:
Weight Loss Percentage = ((200 lbs - 180 lbs) / 200 lbs) * 100 = (20 lbs / 200 lbs) * 100 = 0.1 * 100 = 10%
Therefore, the weight loss percentage for this individual would be 10%.
The weight loss percentage is a useful measure to track progress in a weight loss journey. It represents the proportion of weight lost relative to the starting weight and can serve as a motivating factor to achieve weight loss goals.
