A question about the effects of cutting.

I started consistently lifting at the beginning of summer after not having really lifted since high school, and then got a better routine around the beginning of September and started bulking in October.

I currently try to get in 3000-3500 calories a day, most of it pretty clean, no cardio. On my cut, I'll be eating 2000 calories with quite a bit of cardio on top of weightlifting every day. I'm 5'7" and weigh about 160 and I'm 20 years old.

My plan is to bulk until March, do a 2 week recomp, and then start cutting until the end of August. What I want to know is how much muscle will I lose on a 5 month cut? Obviously my lifts will stall, but I'd like to know what it does to my gains.
