VO2 Max Calculator estimates your maximum oxygen consumption (VO₂ max), which is the gold standard for measuring cardiovascular fitness and endurance. It is widely used in running, cycling, sports training, and health assessments.
This tool provides VO₂ max using heart rate–based estimation or performance tests like the Cooper 12-minute run and Rockport 1-mile walk. Enter your numbers to get your VO₂ max instantly.
VO2 Max Calculator – Estimate Your Aerobic Fitness Level
How This VO2 Max Calculator Works
This calculator uses the validated heart-rate–based formula to estimate your aerobic capacity. VO₂ max represents the maximum amount of oxygen your body can use during intense exercise.
Formulas Used
- HR Method: VO₂ max = 15 × (HRmax / HRrest)
- Cooper 12-Minute Test: Based on total running distance
- Rockport Walk Test: Based on time, heart rate, and weight
Why VO2 Max Matters
VO₂ max is one of the best predictors of endurance performance, cardiovascular health, and overall fitness level.
VO₂ Max Categories
- Poor: < 30
- Average: 35–45
- Good: 45–55
- Excellent: 55+

Is HR-based VO₂ max accurate?
It gives a good estimate but lab tests are more precise.
What is a good VO2 Max score?
Above 45 is considered good for most adults.
How can I improve my VO2 Max?
High-intensity interval training (HIIT) is the most effective method.
