What Is the Navy PRT Calculator?

This Navy PRT Calculator estimates your U.S. Navy Physical Readiness Test (PRT) score. It is specific to the United States Navy and uses a simplified, illustrative scoring model for the three standard events: the forearm plank, push-ups, and the 1.5-mile cardio run. Because the official Physical Readiness Information Management System (PRIMS) tables change periodically and vary by exact age band and gender, this tool gives a clear, easy-to-understand estimate rather than an official score.

How to Use It

Select your gender and enter your age. Then enter your plank hold time in seconds, your total push-ups in 2 minutes, and your 1.5-mile run time in minutes. The calculator converts each event to a 0–100 score and averages them for an overall PRT score and category.

The Formula Explained

Each event is scored on a linear scale between a minimum (passing) threshold and a maximum (Outstanding) threshold:

$$S = 50 + 50 \cdot \frac{x - x_{min}}{x_{max} - x_{min}}$$, clamped to 0–100.

For timed events (plank, run) better means more time held / less time run, so the run is inverted. The overall score is the simple average of the three event scores: $$\text{Overall} = \frac{S_{plank} + S_{pushups} + S_{run}}{3}$$.

Each event earns a score; the three are averaged into the overall PRT score.

Worked Example

A sailor holds a 2:00 (120 s) plank, does 60 push-ups, and runs 1.5 miles in 11:00. With plank min 90 s / max 230 s → score \(\approx 50 + 50 \times \frac{120 - 90}{140} \approx 60.7\); push-ups min 30 / max 80 → \(50 + 50 \times \frac{60 - 30}{50} = 80\); run (inverted) min 14 min / max 9 min → \(50 + 50 \times \frac{14 - 11}{14 - 9} = 80\). Overall \(\approx \frac{60.7 + 80 + 80}{3} \approx 73.6\) — a solid "Good" result.

Overall scores map to fitness categories ranging from Probationary to Outstanding.

FAQ

Is this the official Navy score? No. It is an estimate to help you train. Always check current PRIMS standards for your exact age/gender band.

What passes the PRT? Generally each event must meet at least the Satisfactory minimum; this tool maps the minimum to a score of 50.

Can I use curl-ups instead of plank? The Navy replaced curl-ups with the forearm plank; this calculator uses plank seconds.
