Ollivander is the primary wand maker for the United Kingdom. JK Rowling is on record as saying there are 1,000 students at Hogwarts at any given time. If you believe there are roughly 36 new students per house per year that means he needs to supply around 144 wands per year to new students. The cited article says there are likely significantly less students per year, and Rowling has admitted to being poor at math, but she is on the record...

Now some poorer families don't necessarily buy a new wand right away (such as Ron Weasley), but they probably buy a new one at some point. And wands can be damaged and destroyed (such as Harry's), so that probably evens out.

The other consideration is that the "wand chooses the wizard." Other than when specifically directed to make a wand for a person (such as the replacement wand for Peter Petigrew) he needs to manufacture lots of wands hoping that one of them will choose each prospective customer.

Now he probably spends most of the year constructing wands, builds up a huge inventory before the start of a new school year, and subsequently has it depleted.

So if you count the incoming students for Hogwarts and assume some kind of 0.5% wand loss / replacement for the UK wizard population at large (3000) you'd be looking at Ollivander needing 160 odd wands in stock for the start of term each year.
