Meet the Team Behind Weight Loss Percentage
Weight Loss Percentage was founded with a simple mission: to provide free, accurate, dietitian-reviewed health and fitness calculators. We believe that tracking your health should be scientific, accessible, and easy to understand.
Our team is composed of registered dietitians, clinical nutritionists, and exercise physiologists who review our tools, formulas, and articles to ensure they reflect the latest medical guidelines and evidence-based research.
We do not sell fad diets or unverified supplements. Our tools are designed to empower you with objective calculations to help you take control of your health and weight loss journey safely.

Frequently asked questions
Is this calculator free to use?
Yes. Every calculator on Weight Loss Percentage is free, with no sign-up or account required.
How accurate is the result?
Results depend on the accuracy of what you enter and the published formulas the tool uses, which follow standard guidance from national health authorities. Track the trend over weeks rather than relying on a single reading.
How often should I check it?
Check whenever your weight, activity or goals change — for most people once a week is enough to see a reliable trend.
