Drake Equation Calculator

Estimates the number of advanced Milky Way galaxy civilizations we potentially could communicate with.

Dr. Drake's original estimates are already inputted; type in your own values:

where:

N = number of civilizations
R = ave. star formation rate
fp = % with planetary systems
ne = ave. number of planets that can possibly support life per system
fl = % of the above planets where life actually begins
fi = % of inhabited planets where intelligent life evolves
fc = % of intelligent life that develop technology capable of interstellar communication
L = Lifetime of all fc civilizations on a particular planet
