Max Heart Rate for a 64-Year-Old Woman
The Gulati formula estimates a maximum heart rate of about 150 bpm for a 64-year-old woman. Population variability is roughly ±10–12 bpm, so your true HRmax could sit anywhere between 140 and 160. This page compares the five main formulas at your age and shows how the difference propagates into your training zones.
Gulati estimate: 150 bpm. Likely range 140–160 bpm. The five formulas differ by up to 15 bpm at your age — the comparison table below shows exactly how much.

All Five Formulas at Age 64
| Formula | Equation | HRmax at age 64 |
|---|---|---|
| Fox | 220 − age | 156 |
| Tanaka | 208 − 0.7 × age | 163 |
| Gellish | 207 − 0.7 × age | 162 |
| Nes / HUNT | 211 − 0.64 × age | 170 |
| Gulati | 206 − 0.88 × age | 150 |
Gulati (2010) is generally the most representative for women — it was derived from 5,437 female participants and corrects the systematic overestimation the male-derived formulas produce.

Frequently Asked Questions
What is the maximum heart rate for a 64-year-old woman?
The Gulati formula estimates a maximum heart rate of about 150 bpm for a 64-year-old woman. Your true HRmax is likely between 140 and 160 bpm.
Which formula is most accurate for a 64-year-old woman?
Gulati (2010) is generally recommended for women. It was derived from 5,437 female participants and corrects the systematic overestimation seen with male-derived formulas like Fox and Tanaka.
Why do the five formulas give different results?
Each formula was derived from a different study population. Genetics account for roughly 50% of individual variation in HRmax, so no single equation fits everyone. A supervised maximal effort test is the only way to know your true HRmax.
Can I measure my real HRmax at home?
Yes, if you are healthy and cleared for vigorous exercise. Warm up thoroughly, then perform a 3–5 minute all-out effort finishing with a 30–60 second sprint. Record the peak value on a chest strap monitor. Do not attempt this if you have a heart condition or are on rate-limiting medication.
