VO2 Max Calculator

Estimate VO2 max using the Cooper test or the resting heart rate formula.

How the VO2 Max Calculator Works

This calculator provides two ways to estimate VO2 max. The Cooper test uses the total distance you can run in twelve minutes. The resting heart rate method uses a simple equation based on the ratio of your maximum and resting heart rates. Both are commonly used by runners, cyclists, athletes, and trainers.

The Cooper test formula converts your distance to meters and plugs it into a known equation. The heart rate method uses a general maximum heart rate model. All calculations here are performed in your browser only.

Use this tool to estimate cardio fitness, compare training progress, or combine with other tools such as TDEE and BMR for performance planning.
