Input Parameters

Cycle Time per Unit

\u23f1\ufe0f minutes

Total time to produce one part (including load/unload). Common range: CNC 1\u201310 min, Injection 0.2\u20132 min, Assembly 0.5\u20135 min. To convert seconds, divide by 60 (e.g. 45 sec = 0.75 min).

Hourly Wage (Operator)

$ per hour

Average US manufacturing operator wage: $22\u2013$30/hr (CNC ~$23\u2013$28, Injection ~$23\u2013$25). Use fully burdened rate to include benefits and payroll taxes.

Breakdown

How Cycle Time Converts to Labor Cost

In US manufacturing, direct labor cost per unit is one of the most important variables for accurate quoting and profitability. The formula is simple but powerful:

Labor Cost per Unit ($) = Hourly Wage \u00d7 (Cycle Time in minutes \u00f7 60)

Parts per Hour = 60 \u00f7 Cycle Time (minutes)

1 Cycle Time

Includes machining, molding, handling, and any waiting. Even small reductions (e.g., 30 seconds) can save thousands per year in high-volume runs.

2 Hourly Wage

Use fully burdened rate (base wage + benefits + taxes). US averages: CNC operators ~$23\u2013$28/hr, general machine operators ~$20\u2013$26/hr.

Pro Tip for US Manufacturers

Reducing cycle time by just 10% can drop labor cost per part by the same percentage. Track actual floor cycle times (not theoretical) and focus on bottlenecks \u2014 this is often the fastest way to improve margins without cutting wages.

3 Real-World Examples (US Manufacturing)

Example 1: CNC Machining

Cycle time = 4.5 minutes | Operator wage = $26/hr
Labor cost per part = $1.95 | Parts per hour \u2248 13.3

Example 2: Injection Molding (single cavity)

Cycle time = 45 seconds (0.75 min) | Operator wage = $24/hr
Labor cost per part = $0.30 | Parts per hour = 80

Example 3: Assembly Station

Cycle time = 2.8 minutes | Operator wage = $22/hr
Labor cost per part = $1.03 | Parts per hour \u2248 21.4

Typical US Manufacturing Values

Process	Typical Cycle Time	Avg. Operator Wage	Labor Cost per Part (example)
CNC Milling / Turning	2\u20138 min	$23\u2013$28	$1.15\u2013$3.73
Injection Molding (1 cavity)	0.3\u20131.5 min	$23\u2013$25	$0.12\u2013$0.63
Press Brake / Stamping	0.5\u20133 min	$20\u2013$26	$0.17\u2013$1.30
Manual Assembly	1\u20135 min	$18\u2013$24	$0.30\u2013$2.00

Frequently Asked Questions

Simply divide seconds by 60. Example: 45 seconds = 0.75 minutes. Most US shops measure cycle time in minutes for consistency when calculating labor.

Use fully burdened hourly rate (base wage + benefits, payroll taxes, workers\u2019 comp, and overhead). In the US this is typically 30\u201350% higher than base wage.

Labor cost is directly proportional to time. Cutting cycle time from 5 min to 4 min reduces labor cost per part by 20%.

This tool calculates direct labor cost only. For total conversion cost per part, combine it with the Machine + Labor Cost per Part calculator on TWC Industrial.

They are based on current industry data (BLS, Salary.com). Actual wages vary by state, experience, and union status.

For cells with multiple operators, divide total team labor cost by output, or use the Operator Labor Cost per Machine calculator on TWC Industrial.
