Informational only — not a diagnosis. Estimated maximum heart rate is a general guide, not a medical assessment. See a doctor before starting intense exercise, especially if you have any heart concerns.
- 220 − age
- 190 bpm
- Tanaka (208 − 0.7 × age)
- 187 bpm
The simple 220 − age formula is widely used but has a wide error margin (±10–12 bpm). The Tanaka equation is often more accurate, especially for older adults.

How maximum heart rate is estimated
The best-known formula is simply 220 minus your age. It is easy to remember and widely used, which is why most gym equipment relies on it. However, research has shown it can be off by 10–12 beats per minute for any individual.
The Tanaka equation — 208 − (0.7 × age) — was developed from a large review of studies and tends to be more accurate, particularly for people over 40, where 220 − age increasingly underestimates the true maximum. This calculator shows both so you can compare.
Why it matters
Maximum heart rate is the anchor for heart-rate training. Your zones — from easy recovery to all-out effort — are all calculated as percentages of this number, so a more accurate estimate gives you more useful zones.
It is not a measure of fitness: a higher or lower maximum heart rate does not mean you are fitter. Maximum heart rate is largely determined by age and genetics and naturally declines as you get older, which is normal and expected.
Measuring it accurately
Formulas are estimates. The only way to find your true maximum is a monitored maximal effort test — and that should only be done when you are healthy and, ideally, under professional supervision, as it pushes your heart to its limit.
For everyday training, the formula estimate is perfectly adequate. If you are returning to exercise after a break, are over 40, or have any cardiovascular risk factors, check with your doctor before attempting high-intensity work near your maximum.
Frequently asked questions
Is 220 minus age accurate?
It is a useful rule of thumb but can be off by 10–12 bpm for any individual. The Tanaka formula (208 − 0.7 × age) is generally more accurate, especially for people over 40.
Does a higher maximum heart rate mean I am fitter?
No. Maximum heart rate is set mainly by age and genetics, not fitness. A higher or lower number does not indicate better or worse cardiovascular fitness.
Why does maximum heart rate fall with age?
Age-related changes in the heart’s electrical system gradually lower the maximum rate it can reach. This decline is normal and is why both formulas subtract from a baseline using your age.
