VO2 Max Calculator
A VO₂ Max Calculator estimates how much oxygen your body can use during exercise, giving you an idea of your heart and lung fitness; the higher your VO₂ max, the better your endurance and cardiovascular health, and it can be calculated using your 12-minute running distance or your resting heart rate, age, and gender.

VO₂ Max Calculator – Estimate Your Aerobic Fitness Easily
The VO₂ Max Calculator is a simple and effective tool that helps you estimate your aerobic fitness level and cardiovascular endurance. VO₂ max, or maximal oxygen consumption, is the maximum amount of oxygen your body can utilize during intense physical activity. It’s widely regarded as one of the best indicators of heart and lung health, especially for athletes and fitness-conscious individuals.
What Is VO₂ Max?
VO₂ max stands for “Volume of Oxygen” and refers to the amount of oxygen your body can use per minute, per kilogram of body weight. A higher VO₂ max indicates better aerobic capacity, endurance, and overall health. It is commonly used by athletes, coaches, and healthcare professionals to measure and monitor cardiorespiratory fitness.
What Is a Good VO₂ Max Score?
VO₂ max scores vary based on age and gender. For example, a VO₂ max of 40–50 ml/kg/min is considered average for men, while 35–45 ml/kg/min is average for women. Higher numbers indicate better endurance and fitness.
How Does the VO₂ Max Calculator Work?
This calculator estimates your VO₂ max using two scientifically proven methods:
1. Cooper Test (Distance-Based Method)
This method is based on how far you can run or walk in 12 minutes. The formula used is:
VO₂ Max = (Distance in meters − 504.9) ÷ 44.73
It’s simple and suitable for anyone who can perform a basic running or walking test.
2. Heart Rate–Based Method (Uth & HUNT Formulas)
This method calculates VO₂ max using your age, resting heart rate, and gender. It combines two reliable formulas:
- Uth Formula: VO₂ Max = 15 × (HRmax / HRrest)
- HUNT Formula: VO₂ Max = 211 − (0.64 × age) − (0.75 × resting heart rate) + (12.1 × gender)
These methods are ideal if you don't want to perform a running test and have access to your resting heart rate.
Why Should You Measure VO₂ Max?
Measuring VO₂ max helps you:
- Track your fitness level over time
- Set realistic training goals
- Understand your cardiovascular health
- Personalize your workout intensity

Frequently Asked Questions – VO₂ Max Calculator
What is VO₂ max?
VO₂ max is the maximum amount of oxygen your body can use during intense exercise. It’s a key measure of your aerobic fitness and cardiovascular endurance.
How do I calculate my VO₂ max?
You can calculate VO₂ max using the 12-minute Cooper test (based on distance covered) or using your resting heart rate, age, and gender with formulas like Uth and HUNT.
What is a good VO₂ max score?
VO₂ max varies by age and gender. For example, 40–50 ml/kg/min is considered average for adult men, and 35–45 ml/kg/min is average for women. Higher values indicate better cardiovascular fitness.
Can I improve my VO₂ max?
Yes! Regular aerobic exercises like running, cycling, swimming, and high-intensity interval training (HIIT) can significantly improve your VO₂ max over time.
Do I need special equipment to calculate VO₂ max?
No special equipment is needed. You only need to know your running distance (for the Cooper test) or your resting heart rate, age, and gender (for heart-rate methods).
Is VO₂ max the only way to measure fitness?
While VO₂ max is a strong indicator of aerobic fitness, it should be combined with other metrics like body composition, endurance, strength, and flexibility for a complete picture of your health.
