Body Fat Calculator

Estimate your body fat percentage using circumference measurements and a practical formula.

Why estimate body fat percentage?

Body fat percentage can provide more context than scale weight alone because it helps you understand how much of your body is fat mass versus lean mass.

No formula-based body fat calculator is perfect, but it can still be a useful tracking tool when you use the same method consistently over time.

For the best practical use, combine body fat estimates with weight trend, waist measurements, photos, and performance markers.
