Calculating your estimated vo₂ max is straightforward once you know the VO2 Max formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the VO2 Max Calculator.
What is VO2 Max?
The VO2 Max calculation tells you your estimated vo₂ max from a few simple inputs. The figure you are solving for here is the estimated vo₂ max.
The VO2 Max formula
The core formula is:
Estimated VO₂ max = 15.3 × ((220 - Age) ÷ Resting heart rate)Here is what each input means:
- Age — a value measured in years. Example: 30 years.
- Resting heart rate — a value measured in bpm. Example: 60 bpm.
How to calculate it step by step
- Write down the age (for example, 30 years).
- Write down the resting heart rate (for example, 60 bpm).
- Apply the formula above to get your estimated vo₂ max.
- Double-check the result with the VO2 Max Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Age | 30 years |
| Resting heart rate | 60 bpm |
| Estimated VO₂ max | 48.5 |
| Estimated max heart rate | 190 |
With age of 30 years and resting heart rate of 60 bpm, the estimated vo₂ max works out to 48.5.
Example 2
With age of 60 years and resting heart rate of 60 bpm, the estimated vo₂ max works out to 40.8.
| Result | Value |
|---|---|
| Estimated VO₂ max | 40.8 |
| Estimated max heart rate | 160 |
Example 3
With age of 15 years and resting heart rate of 60 bpm, the estimated vo₂ max works out to 52.3.
| Result | Value |
|---|---|
| Estimated VO₂ max | 52.3 |
| Estimated max heart rate | 205 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- These figures are general estimates, not medical advice — check with a qualified professional before acting on them.
