What is VO2 Max Calculator?
The VO2 Max Calculator estimates your aerobic fitness from three field tests: the Cooper 12-minute run, any race distance and time via the Daniels model, or resting heart rate via the Uth-Sovold formula. Your result lands in one of five fitness classes with an approximate percentile standing.
Key Benefits
- Lab-style fitness number without the lab
- Three methods fit whatever data you already have
- Sex-based classes put your score in real context
- Track training progress month over month
- Instant, private math with nothing stored
Common Use Cases
- •Baseline testing before starting a running plan

How to Estimate Your VO2 Max
- Choose a method: Pick the Cooper 12-minute run, a recent race result, or resting heart rate - whichever data you have.
- Enter your numbers: Cooper needs total meters covered in 12 minutes; race mode needs distance and finish time; the HR method needs age and resting heart rate.
- Select sex for context: Fitness classes use sex-based thresholds, so pick male or female for a meaningful class.
- Read and track: Note your VO2 max, class, and percentile - retest monthly under similar conditions to track progress.
