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.
