Maximum Heart Rate Calculator
Estimates maximum heart rate from age with two formulas: the classic 220 minus age and the Tanaka formula, 208 minus 0.7 times age.
What this calculator does
The Maximum Heart Rate Calculator estimates your result instantly from the values you enter, using standard health & fitness formulas. Estimates maximum heart rate from age with two formulas: the classic 220 minus age and the Tanaka formula, 208 minus 0.7 times age. 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 Maximum Heart Rate Calculator
The Maximum Heart Rate Calculator estimates your peak heart rate from age alone. It shows two figures: the classic 220 − age, and the Tanaka formula, 208 − 0.7 × age.
Both are reported in beats per minute.
Formula & Mathematical Calculation
Max HR (220 - age) = f(Age (years))
Calculated according to standard health formulas implemented in the calculator core.
Calculation Example
At age 30, the classic formula gives 220 − 30 = 190 bpm, and the Tanaka formula gives 208 − 0.7 × 30 = 208 − 21 = 187 bpm.
The tool reports Max HR (220 - age) of 190 bpm and Max HR (Tanaka) of 187 bpm.
Key Benefits
- Shows two widely used maximum heart rate estimates side by side
- Needs only your age
- Includes the more modern Tanaka formula
- Gives results in beats per minute for training zones

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
- Maximum Heart Rate 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.
