BUILT FOR
PRECISION.
BUILT FOR
EVERYONE.
We built PFTCalculator.app with one goal: give Marines, recruits, healthcare professionals, and fitness-driven individuals a fast, reliable tool to understand their fitness and lung health — no fluff, no guesswork.
WHY WE EXIST
The Physical Fitness Test (PFT) and Combat Fitness Test (CFT) are cornerstones of Marine Corps readiness. Yet calculating scores — and understanding what those scores actually mean — has always been more complicated than it needs to be.
We built this platform so that no Marine spends time hunting through tables or doing mental math when they should be focused on training. Whether you’re preparing for your first PFT or tracking improvement over a career, accurate information should be immediate and free.
We also serve healthcare providers and patients who need a fast, clinically-aligned Pulmonary Function Test (PFT) calculator — grounded in established spirometry reference values and designed to complement professional medical care.
THREE TOOLS.
ONE PLATFORM.
USMC PFT Calculator
Score pull-ups/push-ups, crunches, and the 3-mile run in seconds. Instantly see your performance class for your age group and gender.
USMC CFT Calculator
Calculate your Combat Fitness Test score across Movement to Contact, Ammunition Lift, and Maneuver Under Fire events — the way the Corps measures combat readiness.
Pulmonary Function Test
Enter FEV1 and FVC measurements to receive predicted values, percentage comparisons, and airway obstruction interpretation — based on clinical reference equations.
WHAT DRIVES US
Every calculator is built on verified scoring tables and reference equations. We don’t approximate — we compute the same way official graders do.
All calculations happen locally in your browser. Your age, gender, fitness data — none of it ever leaves your device or touches our servers.
Free, forever. No accounts, no subscriptions, no pop-ups. If you need a score, you get a score.
Input your numbers, get your results. We strip out everything that isn’t essential so you can focus on what matters: your performance.
We don’t just return a number — we explain what it means. Understanding your score is as important as knowing it.
