Pricing flight hours

My question: How do you decide what it costs to fly for an hour?

I know the basic idea is to accumulate all the variable costs and fit this
into the price somehow. But, as far as I can tell, this makes an
assumption: that each hour costs the same.

Each hour costs the same for only a certain period of time (usually one year).
You add up all the costs and divide by the number of hours flown that year.
