Max Heart Rate Calculator
Your maximum heart rate (MHR) is the highest number of beats per minute your heart can achieve during all-out effort. This calculator estimates your MHR using three scientifically validated formulas and shows you which is most appropriate for your situation.

How It Works
Three formulas are compared: (1) The Standard formula (220 - age) is the most widely known but least accurate. (2) The Tanaka formula (208 - 0.7 x age) was developed from a meta-analysis of 351 studies and is more accurate for older adults. (3) The Gulati formula (206 - 0.88 x age) was derived from research on women specifically and is recommended for female users.
Quick Reference
| Age | Standard (220-age) | Tanaka | Gulati (Women) |
|---|---|---|---|
| 20 | 200 | 194 | 188 |
| 25 | 195 | 191 | 184 |
| 30 | 190 | 187 | 180 |
| 35 | 185 | 184 | 175 |
| 40 | 180 | 180 | 171 |
| 45 | 175 | 177 | 166 |
| 50 | 170 | 173 | 162 |
| 55 | 165 | 170 | 158 |
| 60 | 160 | 166 | 153 |
| 65 | 155 | 163 | 149 |
| 70 | 150 | 159 | 144 |
Tanaka is recommended for men and older adults. Gulati is recommended for women. Values are estimates with a standard deviation of ~10 bpm.
Frequently Asked Questions
- Which max heart rate formula is most accurate?
- The Tanaka formula (208 - 0.7 x age) is considered more accurate than the traditional 220 - age for most adults, especially those over 40. For women, the Gulati formula (206 - 0.88 x age) may be more appropriate as it was developed from female-specific research.
- Can I exceed my calculated max heart rate?
- Yes. These formulas provide estimates with a standard deviation of 10-12 bpm. Some people naturally have a higher or lower max HR than predicted. If you consistently see higher numbers during all-out effort, your true MHR is likely higher than the formula suggests.
- Does max heart rate decrease with age?
- Yes, maximum heart rate naturally declines with age at roughly 0.7-1 beat per year. This is a normal physiological change and does not necessarily indicate declining fitness. Your training zones should be recalculated periodically as you age.
- How can I find my true max heart rate?
- The most accurate method is a graded exercise test (GXT) supervised by an exercise physiologist. This involves progressively increasing intensity on a treadmill or bike until exhaustion. Many sports medicine clinics in Australia offer this test.
Max Heart Rate Formulas
- MHR
- = estimated maximum heart rate in beats per minute
- age
- = your age in years
The Standard formula (220 - age) is the simplest but tends to overestimate MHR in younger adults and underestimate it in older adults. The Tanaka formula (2001) is based on a meta-analysis of 351 studies with 18,712 subjects. The Gulati formula (2010) was derived from a study of 5,437 women.
