Running Cost 1 : Fixed Payroll and Benefits
Year 1 Labor Burn
Your fixed payroll and benefits commitment in Year 1 is $53,750 monthly, which supports 65 FTEs across all operational roles, including management and machinists. This is your baseline cost before any revenue hits the books. This number sets the minimum revenue target you must clear monthly just to cover salaries.
Payroll Inputs
This $53,750 figure represents the fully loaded cost for 65 employees, covering wages, mandated taxes, and benefits packages. To estimate this accurately, you need quotes for insurance and benefit plans, then multiply the average loaded rate by the planned FTE count. This cost is non-negotiable until headcount changes. Honestly, this is your biggest upfront fixed cost.
- Covers CEO through production staff.
- Includes all mandated employer costs.
- Fixed monthly expense base.
Managing Headcount
Avoid hiring ahead of confirmed production schedules; every new hire adds about $827/month in fixed cost ($53,750 / 65). A common mistake is underestimating the true cost of benefits, which can push the loaded rate 25% to 40% above base salary. Keep hiring lean until machine utilization justifies the next machinist. If onboarding takes 14+ days, churn risk rises.
- Tie hiring strictly to confirmed orders.
- Review benefit package costs early.
- Watch for productivity dips post-ramp.
Break-Even Labor Load
To cover just this payroll cost, your total monthly contribution margin must equal $53,750. Since fixed rent is $12,000 and software is $3,000, your total fixed overhead is $68,750 monthly. You must ensure your machine utilization generates enough gross profit to cover this base load defintely.
Running Cost 2 : Facility Rent
Rent Fixed Cost
Your facility rent is a fixed $12,000 monthly cost, regardless of output. This means the physical footprint is expensive overhead. You must drive high machine utilization rates quickly to cover this base cost effeciently. Honestly, this fixed burden pressures early profitability.
Rent Inputs
This $12,000 covers the combined space needed for your machinery, inventory staging, and office staff supporting 65 FTEs. To budget this correctly, you need signed lease terms for the full facility square footage. It sits alongside other big fixed drains like $53,750 in payroll.
- Input: Lease agreement terms.
- Fixed cost base.
- Compare to payroll load.
Justifying Footprint
You can’t easily cut rent mid-lease, so focus on throughput. If your machines run only 40 hours a week, you are paying for idle capacity. Aim for 85% utilization on high-value CNC centers. Subletting unused warehouse space is an option, but complicates insurance compliance.
- Target 85% machine uptime.
- Avoid leasing excess space.
- Subletting carries compliance risk.
Utilization Pressure
Because rent is fixed, every dollar of revenue generated above variable costs must first service this overhead. If utilization lags in Q1, you’ll burn cash fast. Your immediate focus should be locking in utilization targets for the first three months of operation.
Running Cost 3 : Direct Materials Inventory
Inventory Spend
Direct material costs average $38 per unit across all products, meaning the projected 2026 monthly inventory requirement hits $20,608. This spend covers core inputs like Specialty Steel and Aluminum Alloy needed to meet forecasted production volume.
Material Cost Basis
This $38 per unit cost aggregates all direct materiel inputs required to build one finished component. You calculate the monthly spend by multiplying the projected 2026 unit volume by this average cost. If you don't secure defintely favorable bulk pricing, this baseline expense will pressure early cash flow.
- Average unit cost: $38.
- Monthly spend projection: $20,608.
- Inputs: Specialty Steel, Aluminum Alloy.
Managing Material Flow
Managing this inventory means balancing stockouts against carrying costs. Since these are high-value metals, holding too much ties up significant working capital. Focus on just-in-time delivery for high-cost items to reduce storage needs and improve inventory turns.
- Negotiate volume tiers with metal suppliers.
- Minimize safety stock for expensive alloys.
- Track scrap rates; high precision means low tolerance for waste.
Volume Link
The $20,608 monthly material spend is entirely dependent on achieving the forecasted 2026 production volume, which equates to about 542 units monthly. Any delay in securing anchor Original Equipment Manufacturer (OEM) clients means this inventory requirement drops, but so does revenue potential.
Running Cost 4 : Utilities and Energy
Utility Cost Reality
Your baseline utility budget is $2,500 monthly, but variable factory energy costs, scaling from 6% to 10% of revenue, will be the primary expense driver. Plan for utility volatility tied directly to machine utilization rates, not just the fixed overhead.
Inputs for Variable Spend
This variable cost covers power for CNC machines and climate control in the factory. To estimate it, you must map projected monthly revenue against the 6% to 10% range. For example, $500,000 in revenue means utilities hit $30,000 to $50,000. Honestly, this is a huge swing.
- Map revenue projections to the 6% floor.
- Model high-volume scenarios hitting the 10% ceiling.
- Factory energy is a direct cost of goods sold component.
Managing Energy Draw
Control this cost by scheduling high-draw production runs during off-peak utility rate hours, if your local provider offers them. Ensure machinery meets modern energy efficiency standards to keep the percentage near 6%. A common mistake is letting idle machines draw baseline power, defintely hurting margins.
- Audit peak vs. off-peak rate structures.
- Prioritize equipment upgrades for efficiency gains.
- Set strict shutdown protocols for non-production hours.
Margin Pressure Point
Since variable utilities are revenue-dependent, they directly compress your gross margin alongside Direct Materials ($38 per unit) and Tooling (10% to 14% of revenue). If utilities hit the 10% ceiling, your effective contribution margin drops significantly, making that $53,750 fixed payroll harder to cover.
Running Cost 5 : Software and Systems
Fixed Software Overhead
Your $3,000 monthly software spend is non-negotiable fixed overhead supporting core operations like design and production scheduling. Since this cost doesn't scale with volume, maintaining high utilization across your 65 FTEs is key to covering it efficiently.
Cost Drivers for Systems
This $3,000 covers essential systems, including CAD/CAM software for design, ERP modules for production planning, and the CRM. Compare this to your $53,750 payroll and $12,000 rent; software is a small but necessary fixed layer supporting all output.
- Design tools for custom components.
- Production planning for scheduling jobs.
- CRM tracking OEM client needs.
Managing License Sprawl
Don't over-buy licenses for non-active staff; track seat usage monthly. If you're paying for premium tiers, see if a mid-tier plan meets the needs of your design and planning teams. Bundling services might yield savings, but avoid long-term contracts until volume stabilizes defintely.
- Avoid paying for unused seats.
- Audit premium feature necessity.
- Negotiate annual billing upfront.
Fixed Cost Leverage
Since this $3,000 is fixed, it must be absorbed by volume. If your current revenue projection requires 100 jobs to cover all overhead, those systems must support 100 jobs efficiently, or your unit cost creeps up fast.
Running Cost 6 : Maintenance and Tooling
Hybrid Maintenance Costs
Maintenance involves a fixed $2,000 monthly contract plus variable tooling costs ranging from 10% to 14% of revenue. This cost structure means profitability hinges on maximizing output from existing machine capacity.
Calculating Tooling Spend
The fixed $2,000 covers essential maintenance agreements keeping your precision equipment running. Variable tooling consumables scale directly with production volume; estimate this by taking monthly revenue and applying the 10% to 14% range. This cost is critical for accurate contribution margin analysis.
- Fixed cost: $2,000/month agreement.
- Variable input: Revenue volume.
- Range: 10% to 14% of sales.
Controlling Consumables
Avoid signing long, rigid maintenance contracts; negotiate service levels based on actual machine runtime hours instead of fixed monthly billing. Standardizing tooling across similar machines lets you buy consumables in larger batches, pushing the variable spend toward the 10% floor. A common mistake is ignoring tooling wear tracking.
- Tie fixed fees to utilization.
- Standardize tooling types.
- Bulk buy consumables.
Utilization is Key
Sporadic production runs make the fixed $2,000 maintenance fee expensive leverage. You must maintain high machine utilization to absorb this cost effectively against the variable tooling spend. If client onboarding delays push revenue out, this fixed drain on cash becomes defintely problematic.
Running Cost 7 : Insurance and Compliance
Fixed Compliance Cost
Insurance and compliance costs are a predictable fixed overhead of $1,500 monthly, essential for protecting factory assets and staff. This baseline cost must be covered regardless of production volume.
What This Covers
This fixed $1,500 expense covers property insurance for the facility, general liability protection, and mandatory workers' compensation for your factory staff. It sits alongside $12,000 rent and $53,750 fixed payroll as a core monthly commitment.
- Covers property and liability.
- Includes mandatory workers' comp.
- Fixed at $1,500 monthly.
Managing Premiums
Managing this cost means focusing on risk mitigation rather than just shopping quotes. Since workers' comp is mandatory, ensure accurate classification of shop floor roles to avoid premium spikes. Defintely bundle property and liability coverage for better pricing leverage.
- Review classifications yearly.
- Bundle coverage types.
- Check liability limits against client contracts.
Compliance Risk
Non-compliance with workers' compensation rules stops production fast, especially with factory staff on site. A single audit failure can trigger penalties far exceeding this monthly premium. Always verify coverage renewal dates against your facility rent schedule to prevent coverage gaps.
