CNC Machine Hour Cost Calculator

The CNC machine-hour cost is the fully-burdened dollar cost of running a machining center for one hour — the number you multiply cycle time by to quote a job. It rolls up four buckets every shop pays whether the spindle is cutting or not: the machine's ownership cost, the operator, general shop overhead, and the maintenance and software that keep it running. Estimators, owners, and continuous-improvement engineers use it to price work, compare machines, and justify capital purchases. Quote it too low and you subsidize customers; too high and you lose bids — which is why building it from real components beats guessing a flat rate.

What this calculator does

  • Estimate CNC machine-hour cost by adding machine depreciation, labor, overhead, maintenance, energy, and other hourly burden components.
  • building or checking the hourly CNC rate used in quoting, routing, capacity planning, or make-versus-buy decisions
  • It sums the four hourly cost buckets — depreciation, labor, overhead, and maintenance/software — into a single fully-burdened machine-hour rate.

Formula used

  • CNC machine-hour cost = machine ownership and depreciation + operator labor and supervision + shop overhead, energy, and floor space + maintenance, tooling support, and software
  • Use the same available-hour basis for every hourly component.

Inputs explained

  • Machine ownership and depreciation:
  • Operator labor and supervision:
  • Shop overhead, energy, and floor space:
  • Maintenance, tooling support, and software:

How to use the result

  • Use it when setting or auditing a shop rate, comparing the true cost of two machines, or building a quote from cycle time.
  • The rate is only as honest as your assumed annual available hours — spreading fixed cost over an optimistic utilization makes the rate look artificially cheap.

Current U.S. benchmarks

  • As of Jun 2026, average hourly earnings in U.S. manufacturing are $30.27 (BLS), up 4.4% from a year earlier. Burdened shop rates typically run 1.3 to 1.8 times earnings once benefits and overhead are loaded.
  • The producer price index for steel mill products stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • The U.S. has 17,154 machine shops establishments employing about 223,303 workers (Census County Business Patterns, 2023).

Common questions

  • How do you calculate CNC machine hour cost? Add the four hourly buckets on a common available-hour basis: machine ownership/depreciation, operator labor, shop overhead and energy, and maintenance/tooling/software. Here $42 + $55 + $38 + $18 gives a fully-burdened $153 per hour.
  • What is a typical CNC machine hour rate? It varies widely — small 3-axis mills often land $60 to $120/hr, while large 5-axis or mill-turn centers run $150 to $250+/hr fully burdened. The $153 in this example reflects a mid-to-large machine with a dedicated operator.
  • Does machine hour cost include profit? No. This is cost only — the floor below which you lose money. Add your target margin on top to get the quoted shop rate. Confusing the two is a common way shops quietly under-price.
  • Why use available hours instead of all hours? Fixed costs like depreciation and floor space accrue 8,760 hours a year, but the machine only earns during available production hours. Spreading fixed cost over realistic available hours — not calendar hours — gives an honest rate. Mixing bases is the most common error.
  • Should I use one rate for all my machines? No. A blanket rate over-charges cheap machines and under-charges expensive ones, so you win the wrong work and lose the profitable jobs. Calculate a separate machine-hour cost per machine or machine class.
