FitCalcs provides free fitness and nutrition calculators for informational and educational purposes only. The calculators that use age-based adult formulas are intended for people age 18 or older. If you are under 18, do not use their results for diet, health, or training decisions; ask a parent or guardian and a qualified professional for guidance instead.

2. Not medical advice

The results produced by our calculators are estimates based on standard formulas. They are not medical advice, diagnoses, or treatment recommendations. Always consult a qualified healthcare professional before making significant changes to your diet or exercise routine, especially if you have a medical condition.

3. No warranties

The site and its calculators are provided "as is" without any warranties of accuracy, completeness, or fitness for a particular purpose. We do not guarantee that the results will be correct for your individual circumstances.

4. Limitation of liability

To the fullest extent permitted by applicable law, FitCalcs and its operators shall not be liable for any direct, indirect, incidental, or consequential damages arising from your use of, or inability to use, this site or its calculators. Your use of the site is entirely at your own risk.
