Max Heart Rate Calculator
Estimate HRmax and training zones from age, sex and optional beta-blocker status.
Hit Calculate to see your heart-rate zones

Age formulas are population estimates. A supervised exercise test is more precise, especially with cardiovascular conditions or medications.

Test how your zones change at a different age or resting heart rate.
Calculate your baseline first
The default is Tanaka: 208 − 0.7 × age. You can switch to Fox, Gulati or HUNT to compare common population formulas.
No. Zones are practical estimates based on HRmax and heart-rate reserve. Fitness level, heat, fatigue, caffeine and medications can change real exercise heart rate.
Beta blockers can blunt heart-rate response. Use perceived effort and medical guidance rather than chasing formula-based zones.
Results are estimates generated locally in your browser from common age-based HRmax equations. They are for informational purposes only and are not medical advice, diagnosis, exercise clearance or treatment. Consult a qualified clinician before intense exercise, especially if you have symptoms, cardiovascular disease, pregnancy, or use heart-rate-altering medication.
