Well, if you're using with 5lb increases a session for bench and OHP, and 10lb increases for squat and deadlift...
Every 2 weeks: Bench and OHP should go up 15lbs; Deadlift and Squat should go up 30lbs
Every 3 months: Bench and OHP should go up 90lbs; Deadlift and Squat should go up 180lbs
You could, theoretically, set that as a goal. I don't think it's a good idea. Especially since eventually you'll move to taking smaller jumps, and deloads, and all sorts of things.
Realistically, just focus on beating your numbers week in, week out. If you're not beating your numbers, you're not getting stronger. Whatever it takes to continually beat your numbers is the thing you should be doing... whether that's more recovery, more/less volume, better nutrition, deloads.
And also, log your workouts if you're not already doing it. Log your workouts, how you're feeling that day, if anything is hurting (or feeling better), stuff like that. If you have a bad day in the gym, it helps to know what factors might have affected it. If you keep getting a twinge in your knee when squatting, it helps to track that.
