How We Calculate This
Total beats = age × 365.2425 × 24 × 60 × (restingHR × activityMultiplier). Multipliers: sedentary=1.0, average=1.05, active=1.10.

Frequently Asked Questions
How many times does a heart beat in a lifetime?
On average, the human heart beats about 2.5 to 3 billion times in a typical 70-80 year lifespan, at an average rate of 60-100 beats per minute.
Does resting heart rate affect lifespan?
Studies suggest that a lower resting heart rate is associated with better cardiovascular fitness and potentially longer life. Athletes often have resting rates of 40-60 bpm.
Why include an activity multiplier?
While resting, your heart beats at base rate. During activity, it beats faster. Active people spend more time with elevated heart rates, increasing their daily average.
How much does a heart weigh?
An adult human heart weighs about 250-350 grams (8-12 oz) and pumps about 5 liters of blood per minute at rest.
