Blood Pumped in a Lifetime Calculator
Your heart is an incredible pump that works nonstop throughout your life. Calculate the total volume of blood your heart has pumped since birth and see the result in various units for perspective.
How We Calculate This
Total liters = age × 365.2425 × 24 × 60 × (cardiacOutput × activityMultiplier). Bathtubs = liters/150. Olympic pools = liters/2,500,000.
Frequently Asked Questions
What is cardiac output?
Cardiac output is the volume of blood your heart pumps per minute. At rest, this is about 5 liters per minute for adults. During intense exercise, it can increase to 20-25 liters per minute.
How much blood does the heart pump in a day?
At an average resting cardiac output of 5 L/min, the heart pumps about 7,200 liters (1,900 gallons) of blood per day. That's enough to fill a small swimming pool.
How much blood is in the human body?
Adults have about 4.5-5.5 liters of blood. This means your entire blood volume is pumped through your heart about once every minute at rest.
Does the heart ever rest?
Between beats, the heart relaxes briefly (diastole), but it never truly rests. Over a lifetime, it beats about 2.5-3 billion times without stopping.
