How the calculation works
Fixed ownership cost = initial setup + other ownership costs − estimated resale. Cost per use = fixed ownership cost ÷ planned uses + consumables per use.
Use the result with care
Use the same definition of a use throughout: one project, session or working day. Do not include consumables in both the fixed costs and per-use field. Resale is your assumption, not guaranteed proceeds. This does not measure performance, suitability or the value of your time.
