Max Heart Rate for a 40-Year-Old Woman
The Gulati formula estimates a maximum heart rate of about 171 bpm for a 40-year-old woman. Population variability is roughly ±10–12 bpm, so your true HRmax could sit anywhere between 161 and 181. This page compares the five main formulas at your age and shows how the difference propagates into your training zones.
