Depends on the species. Most species that live in surface waters may live for 5 to 7 years. but cave-adapted species may live for many decades.
The common species of crayfish (crawfish) live about 2 or 3 years, but individuals may live to be as old as 8 years. Some rare species can live as long as 20 years.

After reaching 2 years of age, they have usually grown fairly large and have difficulty creating larger shells beyond a certain size. Each new molting makes them more vulnerable to predators.
they usually live for 20 years (If you take care of them very well)
Crayfish usually live 2-3 years. Some crayfish can live longer than 2-3 years. It depends on their species. :)
