Calculate Your Maximum Heart Rate by Age
Reference values in health come from large population studies (NHANES, WHO). They provide a framework for interpreting your results, but your personal context matters most. We calculate maximum heart rate using the more accurate Tanaka formula: Maximum HR = 208 − 0.7×age (more precise than the traditional 220-age formula). Values are current as of 2026 and reviewed regularly.

How it works
1 min readWhat is Maximum Heart Rate?
Maximum heart rate (Max HR) is the highest number of beats per minute your heart can safely reach during intense physical activity. It's an essential metric for setting proper exercise intensity zones and training safely.
How We Calculate It
We use the Tanaka formula, which is more accurate than the traditional method:
Maximum HR = 208 − 0.7 × Age
This evidence-based formula, developed through research on large population samples, provides better accuracy across different age groups than the older 220-age formula.
Reference Values for Adults
| Measure | Normal Range |
|---|---|
| Resting Heart Rate | 60–100 bpm |
| Blood Pressure | <120/80 mmHg |
| Body Temperature | 98.6°F (36–37.2°C) |
| Blood Oxygen (SpO2) | 95–100% |
| Fasting Blood Glucose | 70–100 mg/dL |
| HbA1c | <5.7% |
| Total Cholesterol | <200 mg/dL |
| LDL Cholesterol | <100 mg/dL |
| HDL Cholesterol | >40 (men) / >50 (women) |

Frequently asked questions
What is maximum heart rate?
Maximum heart rate (Max HR) is the highest number of heartbeats per minute your heart can safely reach during intense exercise. It naturally decreases with age.
How is maximum heart rate calculated?
The Tanaka formula (208 − 0.7×age) estimates your max HR. It's more accurate than the traditional 220-age formula, especially for older adults and those over 40.
Is the Tanaka formula accurate?
The Tanaka formula is more accurate than 220-age for most people. However, it's still an estimate—individual max heart rates vary based on fitness level, genetics, and health conditions.
Do men and women have different maximum heart rates?
The Tanaka formula is the same for both sexes. However, resting heart rate and fitness level vary by individual, affecting how you experience your maximum heart rate.
How do I use maximum heart rate for training?
Calculate your training zones as percentages of max HR: moderate intensity is 50–70% of max HR, vigorous intensity is 70–85%. Multiply your max HR by these percentages.
What are heart rate training zones?
Training zones based on max HR percentages: Zone 1 (50–60%, easy), Zone 2 (60–70%, moderate), Zone 3 (70–80%, hard), Zone 4 (80–90%, very hard), Zone 5 (90–100%, max effort).
When should I see a doctor about my heart rate?
Consult a doctor if you have a resting heart rate consistently above 100 bpm, dizziness, chest pain, shortness of breath, or family history of heart disease.
Can medications affect my heart rate?
Yes. Beta-blockers, stimulants, decongestants, and certain antidepressants can lower or raise your heart rate. Inform your doctor about all medications.
