Maximum Heart Rate (MHR) is the highest number of times your heart can beat per minute (bpm) during maximal physical exertion. It’s an important value for determining exercise intensity zones.

Note: MHR is highly individual and the formulas provided are estimations. A medically supervised stress test is the most accurate way to determine your true MHR.

Common MHR Estimation Formulas:

• Fox (Most Common): MHR = 220 – Age
• Tanaka, Monahan, & Seals: MHR = 208 – (0.7 × Age)
• Gellish: MHR = 207 – (0.7 × Age)
• Gulati (for women): MHR = 206 – (0.88 × Age)
• Londeree and Moeschberger: MHR = 206.3 – (0.711 × Age)
• Miller et al.: MHR = 217 – (0.85 × Age)

This calculator will show results from several of these formulas. If a formula is gender-specific (like Gulati), it will only be applied if the corresponding gender is selected.

Knowing your estimated MHR helps in setting up Target Heart Rate (THR) zones for different types of training (e.g., endurance, fat burning, high-intensity).

Disclaimer: These formulas provide estimates. Individual MHR can vary significantly. Always consult a healthcare professional before starting any new exercise program or if you have concerns about your heart rate during exercise.
