Is Weight Loss Percentage Calculator Worth It? FAQ & Reviews
The calculator uses a simple formula: (Starting Weight - Current Weight) ÷ Starting Weight × 100. You just need to input your starting and current weights, and it instantly computes both the pounds/kilos lost and the percentage of total body weight reduced.
Weight loss percentage accounts for your starting size, making it a fairer comparison between individuals. Medically, specific percentage milestones (5%, 10%, 15%) correlate with significant health improvements, regardless of absolute pounds lost.
Currently, the calculator is only available as a web tool that works on all devices through browsers. There is no dedicated mobile app, but the website is mobile-friendly and functions like an app when saved to your home screen.
For meaningful tracking, experts recommend weighing yourself no more than once per week at the same time of day. Calculating your percentage weekly helps track progress without becoming obsessive about daily fluctuations.
A safe, sustainable rate is typically 0.5-1% of your body weight per week. This translates to 1-2 pounds per week for most people. Rapid weight loss beyond this can be unhealthy and difficult to maintain long-term.
