Navy BCA Calculator
Calculate your Body Composition Assessment using Navy taping standards. SeaBag's BCA calculator walks you through circumference measurements step-by-step and computes body fat percentage against current thresholds.
BCA math is where small mistakes turn into big problems: height and weight screening, body fat tape measurements, BMI rules, age, and gender all matter. Miss the math and you can walk into tape test day thinking you're fine, then leave flagged for a fitness failure. SeaBag removes the guesswork before you stand on the scale, without depending on a Navy website loading at the worst possible time.
