About the Max Heart Rate
Your maximum heart rate is the ceiling your heart can reach during all-out effort, and it anchors every heart-rate training zone. Knowing it lets you set accurate targets instead of guessing how hard to push.
This Max Heart Rate calculator estimates yours using both the classic 220-minus-age formula and the more modern Tanaka equation, so you can compare the two and pick a sensible figure.

How the Max Heart Rate works
This calculator applies standard, peer-reviewed formulas used by health professionals and public-health bodies worldwide. Depending on the metric, that includes the World Health Organization (WHO) classification, NHS and CDC guidance, the Mifflin-St Jeor equation for metabolic rate, and the U.S. Navy method for body composition. Inputs are converted between metric and imperial units using exact factors so results are consistent whichever system you use.
All calculations are performed in your browser, so the health information you enter is never sent anywhere.
Tips & best practices
- These are population estimates — individual maximums vary, so a proper field or lab test is more accurate if you train seriously.
- The Tanaka formula tends to fit older adults better than the classic 220-minus-age rule.
- Never push to true maximum effort without medical clearance if you have any heart condition or risk factors.

Frequently asked questions
