Navy PRT Bike Calculator
Your 12-minute bike test
Estimate only: Guide-5A publishes no bike table, so this calculator estimates your score from the published calories-per-pound method. Your official score comes from the Navy PFA app and is recorded in PRIMS.
Example: a 20–24-year-old man weighing 200 lb who burns 143 calories in 12 minutes scores about 62 points — Good Low, a pass.
Behind the numbers
How the Navy PRT bike score is estimated
The Navy’s 12-minute stationary bike test records the calories on the bike console at 12 minutes. The official Navy PFA app converts that calorie total into an equivalent 1.5-mile run time using your body weight, your sex and the bike model, then scores the run time against the Guide-5A run table for your age group. Guide-5A itself publishes no bike table, so this calculator estimates your score with the published calories-per-pound method from Naval Health Research Center research: the more calories you burn per pound of body weight, the higher your score. Scores above the published anchor points are a straight-line extension of the same scale, and the official app is the only exact source.
Example: 143 ÷ 200 = 0.715 calories per pound, which maps to 62 points (Good Low) on the male 20–24 scale. Older age groups need fewer calories per pound for the same score, matching how the published run tables get slower with age.
Score anchors (calories per pound, age 20–24)
| Points | Category | Male | Female |
|---|---|---|---|
| 45 | Probationary | 0.570 | 0.550 |
| 55 | Satisfactory Medium | 0.590 | 0.573 |
| 62 | Good Low | 0.715 | 0.661 |
| 75 | Excellent Low | 0.950 | 0.820 |
| 90 | Outstanding Low | 1.200 | 1.000 |
The 45, 55 and 62 anchors come from published Official Navy PFA app outputs (a 21-year-old man at 200 lb: 114, 118 and 143 calories; a 21-year-old woman at 171 lb: 94, 98 and 113 calories). The 75 and 90 anchors are a straight-line extension of the same scale.
A few comparisons
Example bike scores
| Sailor | Calories (12 min) | Cal / lb | Score | Result |
|---|---|---|---|---|
| Male, 20–24, 200 lb | 100 | 0.500 | 20 | Fail |
| Male, 20–24, 200 lb | 114 | 0.570 | 45 | Pass — Probationary |
| Male, 20–24, 200 lb | 118 | 0.590 | 55 | Pass — Satisfactory |
| Male, 20–24, 200 lb | 143 | 0.715 | 62 | Pass — Good Low |
| Male, 20–24, 200 lb | 190 | 0.950 | 75 | Pass — Excellent Low |
| Female, 20–24, 171 lb | 94 | 0.550 | 45 | Pass — Probationary |
| Female, 20–24, 171 lb | 113 | 0.661 | 62 | Pass — Good Low |
| Female, 20–24, 171 lb | 140 | 0.819 | 75 | Pass — Excellent Low |
All values are computed with this calculator’s formula. The 20-point floor matches the automatic 20 points given to anyone who stops, rests or stands on the bike during the test.
Burn more calories in 12 minutes.
Your score comes from calories per pound, so the two levers are pedalling harder and weighing less. A steady, hard pace for the full 12 minutes beats sprinting early and fading.
Do not stand up, stop pedalling or rest during the test — that is an automatic 20 points, whatever your calorie total says.
Practice on the same Life Fitness model you will test on. Each console reports calories on its own scale, so a practice number from another bike will not match test day.
Remember the pass rule: 45 points or better on every event. A great bike score cannot rescue a failed push-up or plank event.
Good to know
Your Navy PRT questions, answered.
What is the Navy PRT bike test?
The 12-minute stationary bike is an approved alternate cardio event for the Navy Physical Readiness Test. You ride an approved Life Fitness bike for 12 minutes, and the calories shown on the console at 12 minutes are recorded. A 2-minute cooldown follows, but calories burned during the cooldown do not count.
What score do I need to pass the Navy PRT bike?
You need Probationary, 45 points, or better on every event to pass the PRT, including the bike. For the periodic PRT your overall average across all three events must be at least 50 points (Satisfactory). One event below 45 fails the whole test, no matter how strong the other events are.
How are bike calories turned into a PRT score?
The official Navy PFA app converts your 12-minute calorie total into an equivalent 1.5-mile run time using your body weight, your sex and the bike model, then scores that time against the run table for your age group. Guide-5A publishes no bike table, so this calculator estimates your score from the published calories-per-pound method instead, and the official app is the only exact source.
Which stationary bikes are approved for the Navy PRT?
Only Life Fitness stationary bikes are authorized: the 95CI, the 95C Inspire, the Classic Series and the Integrity Series. Other bikes and ellipticals are not authorized for official PRT testing.
