VO2 Max Calculator
Estimates VO2 max from the distance you cover in a 12-minute Cooper run test, using the Cooper formula: distance in metres minus 504.9, divided by 44.73.
What this calculator does
The VO2 Max Calculator estimates your result instantly from the values you enter, using standard health & fitness formulas. Estimates VO2 max from the distance you cover in a 12-minute Cooper run test, using the Cooper formula: distance in metres minus 504.9, divided by 44.73. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate rather than a certified or official figure.

About VO2 Max Calculator
The VO2 Max Calculator uses the Cooper 12-minute run test. You enter the distance in metres you cover in 12 minutes, and it estimates your maximal oxygen uptake in millilitres per kilogram per minute.
The estimate applies the Cooper formula: (distance − 504.9) ÷ 44.73. Distances of 505 metres or less are rejected.
Formula & Mathematical Calculation
VO2 Max (mL/kg/min) = f(Distance in 12-min Cooper Test (m))
Calculated according to standard health formulas implemented in the calculator core.
Calculation Example
Covering 2400 metres in the 12-minute test gives (2400 − 504.9) ÷ 44.73 = 1895.1 ÷ 44.73.
The tool reports a VO2 Max of about 42.4 mL/kg/min.
Key Benefits
- Estimates VO2 max from a single field test you can run yourself
- Uses the well-known Cooper 12-minute test formula
- Reports the result in mL/kg/min
- Needs only the distance you covered, with no lab equipment
How to Use this Calculator
-
Run the 12-minute Cooper test
Measure how many metres you cover running for 12 minutes. -
Enter the distance
Type that distance in metres into the Distance in 12-min Cooper Test field. -
Calculate
Select Calculate to see your estimated VO2 max in mL/kg/min.
Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
- Results use standard published formulas and account only for the values entered above.
- Rounding is applied for display; the underlying calculation uses your full precision.
- Results are returned in the same units you enter, unless the tool states the output unit.
What it does not cover
- VO2 Max Calculator produces a calculated result for reference and learning, not a certified or official measurement.
- Real-world outcomes differ when tolerances, rounding rules or local standards apply.
- Definitions and standards vary by region and change over time; verify the convention that applies to your case.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For work where the result carries real consequences, confirm it against an authoritative source.
