Body Fat Calculator
Estimate body fat percentage using a simple US Navy style measurement setup.
Why this calculator is useful
Body fat percentage helps you think about composition instead of just total weight, which can be more useful when training or changing habits.
It is still an estimate, but it gives you a more nuanced view than BMI alone.
Use it to watch direction over time, not to obsess over a single reading.

What is my estimated body fat percentage?
These calculators provide practical estimates, not medical advice. Use them as a starting point, then adjust based on how you feel, your routine, and your goals.
How the calculation works
The calculator applies a common Navy-style formula using waist, neck, height, and hip for female measurements.
Because tape measurements can vary, repeat them the same way each time to keep the trend more meaningful.
Practical tips
- Measure at the same time of day whenever possible.
- Keep the tape level and consistent.
- Use monthly checks, not daily checks.
- Combine this with fitness and nutrition trends for a fuller picture.
Recommended next step
Use the result for a few days, notice what feels hard, and make one small adjustment. That keeps the plan useful instead of turning it into another task you have to manage.
