BodyWeightCalculator.org provides general body composition estimates only. It is not a substitute for medical advice or clinical body composition assessment (such as a DEXA scan).
1. General Information Only
All calculators and content on this website (Quick Estimate body fat, Navy Method body fat, lean/fat mass, Weight Trend Tracker) are provided for general informational purposes only, based on published formulas and general population data.
2. Estimation Accuracy Limits
The Navy Method typically carries an error margin of approximately 3-4% body fat compared to clinical DEXA scans. The Quick Estimate (Deurenberg formula) is less precise still, since it relies only on BMI, age, and gender. Neither method should be treated as a clinical measurement.
3. Not Suitable for Diagnosing Medical Conditions
This calculator does not account for medical conditions (such as thyroid disorders, PCOS, or eating disorders), medications, or pregnancy. If you have any relevant condition, follow your doctor's specific guidance instead of this calculator.
4. Weight Trend Tracker Is Not a Medical Record
The Weight Trend Tracker and its moving average calculation are a personal tracking convenience only, stored temporarily in your browser. It is not a substitute for medical records or professional health monitoring.
5. Consult a Professional
Before making significant changes to your diet, exercise, or weight goals based on any result from this site, consult a qualified doctor or registered dietitian who can assess your full health picture.
6. No Liability
BodyWeightCalculator.org, its owners, and contributors accept no liability for any loss, injury, or damage — direct or indirect — arising from reliance on information or calculator results provided on this site. Use of this website and its tools is entirely at your own risk.
7. External Content
Where this site references external sources or links to third-party calculators and articles, we do so for informational convenience only and do not endorse or guarantee the accuracy of that external content.
