Acceptance of Terms
Welcome to Fitness Calculator! By accessing or using our website and calculators, you agree to be bound by these Terms of Use. If you don't agree with any part of these terms, please don't use our site.
In plain English: By using our calculators, you're agreeing to these terms. If you don't like them, that's okay—just don't use the site.

- BMI (Body Mass Index) Calculator
- Body Fat Percentage Calculator
- Calorie Needs Calculator
- Ideal Weight Calculator
- Macro Calculator (macronutrients)
- Protein Intake Calculator

Educational Purpose Only
IMPORTANT: Our calculators are for educational and informational purposes only. They are NOT medical advice.
The results provided by our calculators are estimates based on standard formulas and general population data. They should not be used as:
- A substitute for professional medical advice
- A diagnosis of any health condition
- A personalized health or fitness plan
- Guidance for specific medical treatments or interventions
Always consult with qualified healthcare professionals (doctors, nutritionists, personal trainers, etc.) before making significant changes to your diet, exercise routine, or lifestyle based on calculator results.
No Warranties
We provide our calculators "as is" and make no guarantees about:
- The accuracy of calculations
- The suitability of results for your specific situation
- The website being available 24/7 without interruptions
- Results being appropriate for everyone
While we strive for accuracy using well-established formulas (like the Harris-Benedict equation for calories or the U.S. Navy method for body fat), individual results can vary significantly based on factors we can't account for in simple online calculators.
Limitation of Liability
To the maximum extent permitted by law, Fitness Calculator and its creators are not liable for:
- Any health problems or injuries arising from using our calculators
- Decisions made based on calculator results (dietary changes, exercise routines, etc.)
- Errors or inaccuracies in calculations
- Lost data or interrupted service
- Any indirect, incidental, or consequential damages
Use our calculators at your own risk. We're providing helpful tools, but you're responsible for how you use the information.

- Attempt to hack, disrupt, or damage the website or its infrastructure

Normal use of the calculators, even heavy use, is perfectly fine. We just ask that you don't try to break things or steal content.

Bottom Line (Not Legal Advice)
