Effective Hourly Cost
Accounting for 65% utilization rate (industry average for productive cutting time):
This is the true cost per productive cutting hour, accounting for setup, material handling, and downtime.
Data Sources & Methodology
$0.0755/kWh from U.S. Energy Information Administration (EIA) 2024 Q3
$0.30/m³ from industrial gas supplier averages (Air Liquide, Linde, Praxair 2024)
8% annual rate from Trumpf TruLaser service documentation
$28.50/hour from U.S. Bureau of Labor Statistics (BLS) 2024
Calculation Methodology
Cost Components
- Electricity: System power consumption = Laser power × consumption multiplier (1.35x for fiber, 1.60x for CO2 to account for chillers, motion systems, controls)
- Assist Gas: Consumption rate × regional gas prices. Nitrogen is typically 5-10× more expensive than oxygen but required for oxide-free cutting.
- Maintenance: Annual maintenance is 8% (fiber) or 12% (CO2) of equipment price, distributed across operating hours.
- Consumables: Nozzles, lenses, protective windows averaging $2.50-3.50/hour depending on laser type.
- Labor: Regional operator wages including benefits (typically 1.3-1.4× base wage).
- Other: Facility costs, cooling water, miscellaneous supplies (~7% of direct costs).
Data Sources
- Electricity Rates: U.S. Energy Information Administration (EIA) 2024 Q3, European Energy Exchange (EEX) 2024 Q3, China Electricity Council 2024

Usage Guide & Real-World Examples
How to Use This Calculator
- Select Equipment Parameters: Enter your laser power (kW) and type (fiber or CO2). If planning a purchase, use the recommended power from our Power Calculator.
- Set Operating Schedule: Input realistic operating hours per day and days per week. Consider: single shift (8h), double shift (16h), or triple shift (24h) operations.
- Choose Assist Gas: Select gas type based on your primary materials:
- Oxygen: Carbon steel (lowest cost, fastest cutting)
- Nitrogen: Stainless steel, aluminum (oxide-free edges, 5-10× oxygen cost)
- Compressed Air: Thin materials, low-cost applications
- Mixed: Varied production (oxygen + nitrogen)
- Set Gas Consumption: Typical ranges: 1-3 m³/h (oxygen), 2-5 m³/h (nitrogen). Higher power and thicker materials require more gas.
- Select Region: Choose your location for accurate electricity and labor rates. You can override with custom rates if needed.
- Specify Operators: Most operations require 1 operator. Add more for high-volume or multi-machine operations.
- Review Results: Check hourly, daily, monthly, and annual costs. The "Effective Hourly Cost" accounts for 65% utilization (industry average).
Real-World Cost Examples
Example 1: Small Job Shop (3kW Fiber, United States)
Configuration:
- • Laser: 3kW Fiber
- • Schedule: 8 hours/day, 5 days/week
- • Gas: Oxygen, 2 m³/hour
- • Location: United States
- • Operators: 1
Estimated Costs:
- • Hourly: ~$35-40
- • Daily (8h): ~$280-320
- • Monthly: ~$5,600-6,400
- • Annual: ~$67,000-77,000
Typical for small shops cutting carbon steel brackets, enclosures. Single shift operation keeps labor costs manageable while providing good productivity.
Example 2: Mid-Size Fabricator (6kW Fiber, United States)
Configuration:
- • Laser: 6kW Fiber
- • Schedule: 16 hours/day, 5 days/week
- • Gas: Mixed (Oxy + N2), 3 m³/hour
- • Location: United States
- • Operators: 2 (shift rotation)
Estimated Costs:
- • Hourly: ~$70-80
- • Daily (16h): ~$1,120-1,280
- • Monthly: ~$22,400-25,600
- • Annual: ~$269,000-307,000
Double shift operation maximizes equipment utilization. Mixed gas supports varied production (carbon steel with oxygen, stainless with nitrogen). Labor becomes ~40% of total cost.
Example 3: High-Volume Production (12kW Fiber, China)
Configuration:
- • Laser: 12kW Fiber
- • Schedule: 20 hours/day, 6 days/week
- • Gas: Nitrogen, 4 m³/hour

- • Monthly: ~$31,000-36,000
- • Annual: ~$374,000-436,000
High-volume stainless steel production. Lower China labor costs offset expensive nitrogen usage. Nearly continuous operation (20h/day) maximizes ROI on high-power equipment.
Example 4: European Precision Shop (6kW Fiber, EU)
Configuration:
- • Laser: 6kW Fiber
- • Schedule: 10 hours/day, 5 days/week
- • Gas: Nitrogen, 3 m³/hour

European energy costs (2.4× US rates) and higher labor rates increase hourly costs. Nitrogen cutting for high-quality stainless steel parts. Moderate schedule balances cost control with productivity.
💡 Cost Optimization Tips
Reduce Gas Costs
- • Use oxygen for carbon steel (5-10× cheaper than nitrogen)
- • Negotiate bulk gas contracts (>30% savings possible)
- • Optimize cutting parameters to reduce gas consumption
- • Consider on-site nitrogen generator for high-volume nitrogen use
Reduce Electricity Costs
- • Schedule heavy cutting during off-peak hours (time-of-use rates)
- • Fiber lasers use 40-60% less power than CO2 for metals
- • Maintain proper chiller operation (dirty chillers = higher power)
- • Power down system during extended idle periods
Reduce Maintenance Costs
- • Follow preventive maintenance schedules (avoid costly breakdowns)
- • Train operators on proper consumable installation
- • Use genuine OEM parts (cheaper knockoffs fail faster)
- • Fiber lasers have 50% lower maintenance than CO2
Maximize Utilization
- • Improve nesting efficiency (reduce material waste & cutting time)
- • Automate material handling (reduce manual setup time)
- • Cross-train operators (minimize downtime during shifts)
- • Batch similar jobs (reduce setup & changeover time)
