Calculate Navy Physical Readiness Test scores for push-ups, plank, 1.5-mile run, and body composition assessment with age/sex-specific standards.
The Navy Physical Readiness Test (PRT) is the semi-annual fitness assessment required for all active-duty and reserve Navy personnel. The PRT consists of two components: the Body Composition Assessment (BCA) and the Physical Readiness Test proper, which includes a muscular strength/endurance event (push-ups or forearm plank), and a cardiorespiratory event (1.5-mile run, 500-yard swim, 2,000-meter row, or stationary bike).
This calculator computes body fat percentage using the official US Navy circumference method, evaluates push-up and forearm plank performance, and scores the 1.5-mile run against age- and sex-specific standards. Each event is categorized as Outstanding, Excellent, Good, Satisfactory, or Fail, with the overall PRT score determined by the lowest individual event score. All events and BCA must be passed for an overall passing PRT cycle.
The Navy updated PRT standards in 2022, replacing curl-ups with the forearm plank as the core strength event and adding alternative cardio options. Standards are calibrated by age group (17-19 through 65+) and sex, with separate tables for each combination. Sailors who fail the PRT face administrative consequences including fitness enhancement program enrollment and potential separation after consecutive failures.
This calculator helps active-duty and reserve Navy personnel prepare for the PRT by understanding exactly where their performance falls relative to official standards. It also helps fitness leaders quickly assess sailor readiness and identify areas needing improvement. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.
Navy BF% (male) = 86.010 × log₁₀(waist − neck) − 70.041 × log₁₀(height) + 36.76. Navy BF% (female) = 163.205 × log₁₀(waist + hips − neck) − 97.684 × log₁₀(height) − 78.387.
Result: BF 16.3% (Excellent), Push-ups Good, Plank Excellent, Run Excellent — Overall: Good (PASS)
A 25-29 male with body fat 16.3% (Excellent), 55 push-ups (Good), 150-second plank (Excellent), and 11:30 run (Excellent) receives an overall Good score since the lowest event determines the overall category.
The Navy has used the circumference-based body fat estimation method since the 1980s, based on research conducted at the Naval Health Research Center. The original Hodgdon-Beckett equations remain the core of the BCA. While more sophisticated body composition methods exist (DEXA, BodPod, bioelectrical impedance), the circumference method was selected for its practicality — it requires only a tape measure and can be administered anywhere, including shipboard. The Navy periodically reviews BCA standards and has adjusted maximum body fat allowances several times, most recently in 2023.
Successful PRT preparation requires a structured training program addressing all three components. For push-ups, progressive overload through incline push-ups, weighted push-ups, and time-under-tension variations builds the muscular endurance needed for the 2-minute event. For the plank, core training should include both static holds and dynamic movements (dead bugs, bird dogs, Pallof presses). For the 1.5-mile run, a combination of easy aerobic base runs, tempo runs, and short interval work (200-400m repeats) produces optimal improvement.
The circumference-based BCA has been criticized for potentially penalizing muscular individuals whose waist measurements fail despite low body fat. Conversely, it may pass individuals with dangerous visceral fat distribution who happen to have favorable circumference ratios. The Navy has explored alternatives including DEXA scanning, but logistical constraints of testing thousands of sailors make circumference measurement the only practical large-scale option. Sailors who fail BCA screening by tape can request a command-funded DEXA scan as an alternative.
The Navy circumference method uses a regression equation based on height, waist, and neck measurements (plus hips for females) validated against hydrostatic weighing. While less accurate than DEXA or hydrostatic weighing for individuals, it provides a standardized, equipment-free method suitable for mass screening. It tends to underestimate body fat in very muscular individuals and overestimate in those with high visceral fat but low subcutaneous fat.
The Navy replaced the 2-minute curl-up with the forearm plank in 2022 because the curl-up had higher injury rates (neck strain, lower back aggravation), poor correlation with actual core stability needed for Navy operations, and did not align with current exercise science evidence. The forearm plank better assesses isometric core endurance and has a much lower injury rate while testing the same fitness domain.
After a first PRT failure, sailors are enrolled in the Fitness Enhancement Program (FEP) and given a remedial PRT. Consecutive PRT failures lead to progressively serious administrative actions: adverse fitness reports/evaluations, loss of advancement eligibility, and ultimately, processing for administrative separation. Three or more consecutive PRT failures constitute a basis for separation. The Navy emphasizes that PRT readiness is a year-round responsibility.
Yes. The 2022 PRT update allows alternative cardiorespiratory events: 500-yard swim, 2,000-meter row on a Concept2 rower, or 12-minute stationary bike test. Each alternative has its own scoring tables. The 1.5-mile run remains the most common. Alternative events were introduced to reduce running injuries and accommodate sailors with running limitations while still assessing cardiorespiratory fitness.
Measurements must be taken by a certified Command Fitness Leader (CFL). Waist is measured at the navel level, standing naturally with arms at sides. Neck is measured just below the laryngeal prominence (Adam's apple), perpendicular to the long axis of the neck. Hips (females only) are measured at the widest point. All measurements are taken to the nearest ½ inch. Two rounds of measurements are taken; if they differ by more than 1 inch, a third round is performed.
For normal duty, Satisfactory or above is passing. However, competitive programs and advancement may require higher scores. For example, some special warfare programs require Outstanding or Excellent in all events. High PRT scores are reflected in evaluation/fitness report grades and can influence advancement recommendations. Some commands set local standards above the Navy minimum for their personnel.
