    Maximum Heart Rate: 220−Age & Tanaka

    Compare age-predicted maximum heart-rate equations and explain individual variability.

    How to use the Maximum Heart Rate Calculator

    1. Enter age.
    2. Select any method, activity level or option shown on this page, then choose Calculate.
    3. Read the main result together with the supporting values, method, assumptions and limitations below before using the estimate.

    How this calculation works

    Heart-rate tools use transparent age-predicted maximum-heart-rate equations and, where selected, heart-rate reserve (Karvonen) arithmetic.

    Method transparency: Results are calculated from the values you enter. Health estimates are educational reference values, not diagnoses or treatment advice.

    Example calculation

    The sample values loaded into the calculator produce 185 bpm. This example exists to show how the output is structured; replace the sample values with your own inputs for your calculation.

    Assumptions and limitations

    • Energy, fitness and heart-rate outputs are estimates and vary by individual and device.
    • Stop exercise and seek appropriate care if you have concerning symptoms; this tool does not provide medical clearance.

    Questions people ask about Maximum Heart Rate Calculator

    Is 220 minus age my exact maximum heart rate?

    No. It is an age-predicted estimate. The page also shows a Tanaka comparison because individual maximum heart rate can differ substantially from either equation.
