With a total shoot count of about 5000 to 8000 shots a years shooting target and 3D and practice, plus about 1 or 2 shots every five years while hunting a dozen arrows may last me about 5 years give or take a year.

Heck, I've still got 9 of the original dozen ACC's I bought ten years ago. That's partly because I'm constantly changing equipment to see what else works and how well.

Let's see. Last year I got a dozen GT Pro 22's. Have had them about 1 1/2 years total. I've wrecked one and robin-hooded one. So got 10 left, so I should be good for another five years.
