Not necessarily. Battery performance depends on several things. Apple recommends that you "keep the electrons moving". The battery system is ideally designed for a commuter type situation: run on battery for a few times a week and recalibrate every two months. If you leave your MacBook plugged in all the time then you should recalibrate once a month.
Its a balance between load cycles and battery-only usage.
If you completely drain daily, your battery will probably last 18 months or about 500 load cycles before it drops below 50% capacity.
