Buyer's guide

How to choose a body fat calculator

When picking a body fat calculator, decide whether you want a quick height/weight-only estimate or a more accurate method that uses waist, neck, and hip measurements. If you have a tape measure and want the U.S. Navy method, Calculator.net gives you the full picture including how many pounds you need to lose. If you don’t want any data leaving your browser and you’re okay with fewer unit choices, MyFatCalc keeps everything local.

Questions

Body Fat Calculator FAQ

Can I use these calculators without measuring my waist and neck?
The U.S. Navy method is widely used and considered more accurate than BMI alone because it accounts for fat distribution, but it is not a medical diagnosis. Results are estimates and should be discussed with a healthcare provider.
Do these tools store my measurements?
MyFatCalc guarantees that your inputs stay local and are not uploaded, while the other tools do not make that claim in the provided excerpts.
Which method is most accurate for tracking fitness progress?
The U.S. Navy method is more precise than BMI for tracking fitness progress because it uses multiple body dimensions rather than just height and weight.
Can I switch between metric and imperial units?
Calculator.net and MyFatCalc both support switching between metric and imperial units without losing context.
