Max Heart Rate Calculator
Estimate maximum heart rate with the classic 220 − age formula and the Tanaka formula (208 − 0.7 × age). An estimate with a typical error of ±10–12 bpm — a lab or field test is the only precise measure.
Your estimated maximum heart rate
187 bpm (Tanaka) · 190 bpm (220 − age)
The two formulas differ by 3.0 bpm at your age. A reasonable working figure is about 189 bpm — but the true value varies by ±10–12 bpm between people of the same age.
| Tanaka (2001) | 187.0 bpm |
| Classic 220 − age (Fox, 1971) | 190 bpm |
| Typical error of either formula | ±10–12 bpm |
A lab test (or a hard all-out field test with a chest strap) is the only precise measure of HRmax. If you have a heart condition, do not do a max test without medical clearance.
Formula & source — HRmax formulas — Fox et al. (1971); Tanaka et al. (2001)
Classic: HRmax = 220 − age (Fox, Naughton & Haskell, 1971). Tanaka: HRmax = 208 − 0.7 × age (Tanaka, Monahan & Seals, Journal of the American College of Cardiology, 2001). Tanaka's meta-analysis of 351 studies found 208 − 0.7 × age predicts HRmax better across the lifespan. Both have a typical error of ±10–12 bpm.
