Experience will tell you how much.
I use about 5 cord/year with an old airtight stove. Some here with newer stoves use a similar amount.
Some however, use about 3.
It's actually a big mystery until you've gotten a couple seasons under your belt.
How big the house is, how well it's insulated, do you burn 24/7 or just nights and weekends, do you like it 68 or 75 in the house are all factors. There are more, but that should give you an idea how tough it is to answer the question.
Knowing what you have is the only way to know how much you've used, and how much to get ready for next year.
I never kept track on how much wood I used but it would be nice how much so I can plan ahead.
