Exactly. (Purchase price - salvage value) / years = depreciation expense per year. This is standard cost accounting. Any accounting class, review and advice by a CPA, federal purchasing standards etc will include this cost in any analysis. (BTDT, 20 years reviewing purchase contracts for reasonableness). Accelerated, front-loaded depreciation allowed for tax reporting will give different numbers and may or may not be relevant for a purchase decision.No offense meant or intended, but consult https://www.extension.iastate.edu/agdm/crops/html/a3-29.html to see the way economists compute annual ownership costs.
Also in making a decision to purchase, 'Opportunity Cost' must be considered. Assuming you pay cash for the tractor then this is what that same investment could earn if you invested it in some other income-producing activity; the other income that you are giving up in order to make this purchase. Interest cost if you finance the tractor will approximate this number.
Most of us have some intuitive feel for these numbers without getting all formal about it, and can afford our toys. But any small business starting out needs to carefully analyze, and understand, these concepts. Lots of failed businesses had no idea what their costs ... were.
