CPTR Calculator helps Marines quickly calculate body composition and circumference measurement results in accordance with MCO 6110.3A, the Marine Corps Body Composition and Military Appearance Program order. Enter your height and circumference measurements to instantly calculate your body fat percentage using the official male or female circumference tables. If a measurement appears to be an outlier, the app flags it and asks you to verify the entry before calculating. If your body fat percentage exceeds the standard, enter your PFT and CFT scores to determine whether you qualify for a performance-based exception, including the 285 PFT/CFT exemption and the 1% high-performer allowance. FEATURES • Fast, accurate body composition calculations based on MCO 6110.3A • Complete PFT/CFT exception handling, including the 285 exemption and 1% allowance • Male and female circumference tables • Automatic outlier detection • Dark mode support • Works entirely offline—no account or internet connection required • No advertisements, data collection, or tracking CPTR Calculator is a simple, focused tool designed to reduce manual calculations and table lookups.
