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.

Machine hour cost vs labor rate, what's the difference?

Labor rate is just the operator portion ($55/hr here). Machine-hour cost is the full burden including the machine, overhead, and upkeep, $153 total. Quoting on labor alone ignores two-thirds of what running the spindle actually costs.

CNC Machining calculator

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 Jul 2026, average hourly earnings in U.S. manufacturing are $30.35 (BLS), up 4.2% 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 374.203 (BLS, Jul 2026), up 22.5% 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).
