How do you calculate direct labor cost?

Multiply direct labor hours by the loaded hourly wage and by the productive time share, then add any fixed shift premium. With 320 hours, a $34 loaded wage, 88% productive time and an $800 premium you get 320 × 34 × 0.88 + 800 = $10,374.40.

What is a loaded wage vs. base wage?

Base wage is the operator's stated hourly pay. Loaded (or fully burdened) wage adds payroll taxes, benefits, PTO accrual and workers' comp — typically 25-45% on top of base — which is why the $34/hr used here is higher than a posted pay rate.

Why include a productive time share?

Because paid hours are not all value-adding hours. At 88%, 12% of the paid time is absorbed by breaks, meetings, waiting and material handling. Costing at 100% understates the true labor content of each good part.

What is the direct labor cost per unit here?

Dividing the $10,374.40 total by the run's unit count yields $32.42 per piece in this example — the number you'd load into a part's standard cost or a quote.

Should shift premiums be in direct labor cost?

Yes when the premium is tied to running the job — a night-shift differential or weekend pay. Here the $800 is a fixed adder, so it shows up as the fixed portion ($800) separate from the variable $9,574.40.

Direct labor cost vs. indirect labor cost — what's the difference?

Direct labor is traceable to a specific product (the operator on the press). Indirect labor — supervisors, material handlers, quality inspectors — supports production but isn't tied to one unit, and is usually recovered through an overhead or indirect-labor rate instead.

Direct Labor Cost Calculator

Direct labor cost is the money you pay operators, assemblers and machine tenders whose hands actually touch the product, expressed in real dollars for a run or a period. Cost accountants, plant controllers and estimators use it to build standard costs, quote jobs and reconcile the labor variance on a work order. It matters because direct labor is usually the second-largest controllable line on a manufactured part after material, and small errors in the loaded wage or productive-time assumption compound across every unit you ship.

What this calculator does

Calculates the direct labor cost of a job from hours worked, a loaded wage, and the productive share of clocked time.
A cost estimator uses it to price the hands-on labor content of a job before adding overhead and material.
It multiplies direct labor hours by the fully loaded wage and the productive time share, then adds any fixed shift premium to give total and per-unit direct labor cost.

Formula used

Direct labor cost = labor hours x loaded wage x productive time share + shift premium
Direct labor cost per hour = direct labor cost / labor hours

Inputs explained

Direct labor hours worked:
Loaded hourly wage (wage + burden):
Productive time share (value-add %):
Shift premium / off-shift adder:

How to use the result

Use it when standard-costing a part, quoting a production run, or checking whether an earned-hours labor variance is driven by rate or by lost productive time.
It treats the productive time share as a flat percentage; real shrink from breaks, changeovers and rework varies by shift and station, so validate the assumption against timekeeping data before trusting the per-unit figure.

Current U.S. benchmarks

Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
