Running Cost 1
: Payroll and Instructor Wages
Largest Fixed Cost
Payroll is your biggest fixed expense, hitting $34,583 monthly by 2026, driven by 50 FTE staff including trainers and managers. Managing this large personnel base is key to controlling your overall burn rate, so watch utilization closely.
Staffing Cost Drivers
This $34,583 monthly figure represents the total compensation for 50 FTE roles, split between hands-on instructors and necessary management overhead for 2026. Since this is a fixed cost, it must be covered regardless of training group volume. You need detailed salary schedules for instructors versus admin staff to defintely refine this estimate.
Covers 50 FTE staff total.
Includes instructors and management.
Fixed cost projection for 2026.
Optimizing Instructor Pay
You can't cut instructor quality, but you can optimize scheduling. Use highly skilled contractors for peak demand spikes instead of hiring full-time staff too early. If onboarding takes 14+ days, churn risk rises among new hires waiting for paychecks. Keep management lean until revenue scales past $100k/month.
Use contractors for variable load.
Optimize instructor utilization rates.
Keep management lean initially.
Fixed Cost Leverage
Because payroll is fixed, your break-even point hinges entirely on maximizing the utilization of those 50 FTE employees. If instructor time isn't fully booked delivering high-margin training cohorts, this large fixed cost quickly erodes all contribution margin from your revenue streams.
Running Cost 2
: Equipment Storage Rent
Fixed Storage Cost
You need a dedicated space for that Mobile Simulation Training Trailer. This fixed cost hits at $4,500 per month. It's non-negotiable overhead supporting your core physical assets. If you skip this, you can't run onsite training sessions effectively.
Warehouse Budget Input
This $4,500 monthly warehouse rent is a fixed operating expense. It directly supports the Mobile Simulation Training Trailer and all heavy gear required for hands-on certifications. You must budget this amount every month, regardless of training volume, as it's part of your baseline overhead, sitting below payroll.
Covers storage for heavy gear.
Fixed at $4,500/month.
Essential for mobile unit readiness.
Storage Cost Control
Since this cost supports the core training asset, cutting it risks operational failure. Look for 12-month lease discounts instead of month-to-month rates to save cash flow. If the trailer is frequently deployed, investigate secure, off-site staging near client hubs to reduce long-term facility needs; defintely review space needs quarterly.
Seek annual rate locks.
Review space needs quarterly.
Avoid month-to-month premiums.
Fixed Overhead Anchor
The $4,500 storage payment is a necessary fixed cost, sitting alongside payroll ($34,583) and insurance ($1,200). It anchors your ability to deliver the hands-on training component that differentiates you from online-only competitors. This spend must be covered before you generate any revenue.
Running Cost 3
: Professional Insurance
Mandatory Insurance Cost
Professional Liability Insurance for this operation is a fixed, mandatory cost of $1,200 monthly. Because training involves high-risk confined space entry and rescue, this coverage protects against claims arising from professional negligence. It's a cost you can't negotiate away.
Estimate Inputs
This $1,200 monthly premium covers Professional Liability (Errors & Omissions) insurance. You need quotes based on anticipated annual revenue and the specific risk profile of confined space training. It stacks directly onto your fixed overhead, sitting below payroll but above software costs in the budget structure.
Risk profile assessment.
Annual revenue projections.
Quote comparison across carriers.
Cost Control
You can't cut the coverage, but you can manage the price. Shop carriers annually, but don't chase the lowest bid if the deductible is too high. Maintaining zero claims defintely helps lower renewal rates over time. Focus on flawless execution in every class.
Bundle policies if possible.
Increase the policy deductible.
Document all safety protocols well.
Fixed Cost Impact
Considering your $34,583 payroll and $4,500 storage rent, this $1,200 insurance fits into the fixed base cost structure. It must be covered before you reach break-even, regardless of how many training cohorts you sell that month.
Running Cost 4
: Certification Materials (COGS)
Materials as Variable Cost
Your certification processing and materials are a major variable expense, hitting 45% of revenue right out of the gate. This cost scales directly with every training group you successfully process. If you process ten groups, you incur materials cost on ten groups; it's a direct volume link.
Inputs for Material Costing
This 45% Cost of Goods Sold (COGS) covers physical items like workbooks, testing fees, and official certification cards for each trainee. To model this accurately, you need the expected number of trainees per group multiplied by the per-person cost of materials and processing fees. It's a direct per-head expense, so group size matters a lot.
Determine per-trainee material cost.
Track expected group size variance.
Calculate total materials based on volume.
Managing Material Spend
Managing this 45% requires negotiating bulk rates with your certification body or material supplier upfront. Avoid over-ordering supplies based on optimistic projections; inventory waste hits your margin fast. Standardize group size targets to maximize material efficiency per cohort, which helps control the variable spend.
Negotiate supplier volume discounts.
Track material usage per trainee precisely.
Standardize cohort size targets.
Margin Impact
Since materials are a 45% variable expense, your gross margin starts low, around 55%. This means every dollar of revenue must first clear this high hurdle before it can start covering fixed overhead, like the $34,583 monthly payroll, to reach profitability.
Running Cost 5
: Vehicle Fleet Maintenance
Fleet Readiness Budget
You need a fixed $1,800 per month set aside just for fleet maintenance. This covers the Heavy Duty Transport Vehicle and all related assets necessary to deliver your onsite training programs. Keeping this budget separate ensures your mobile units are always ready to meet client demands without unexpected downtime derailing revenue targets. It's non-negotiable overhead.
Maintenance Allocation
This $1,800 allocation is a fixed overhead line item, not tied to revenue volume. It must cover scheduled servicing, unexpected repairs, and ensuring the Heavy Duty Transport Vehicle is operable. Budget this monthly from day one, treating it like insurance for your physical delivery mechanism. This cost supports your goal of providing hands-on certification.
Controlling Vehicle Spend
Avoid letting this become variable by sticking strictly to preventative maintenance schedules. Emergency repairs on heavy transport vehicles cost significantly more than planned service visits. If you skip routine checks, you risk a breakdown that costs 5x the monthly budget in towing and emergency fixes. Don't skimp here; operational readiness is key.
Operational Reality Check
Operational readiness hinges on this budget line. If the primary transport vehicle fails inspection or breaks down, you cannot conduct onsite training, immediately halting revenue generation. Factor $1,800 into your monthly burn rate regardless of sales volume; it's a cost of keeping the doors open for service delivery.
Running Cost 6
: Travel and Fuel
Fuel Cost Dominance
Travel and Fuel starts at 60% of revenue, immediately squeezing margins because training is delivered onsite via the mobile unit. Until you increase order density, every new training session adds significant, unavoidable variable expense.
Cost Inputs
This 60% covers fuel and operational costs for moving the Mobile Simulation Training Trailer. Estimate this by multiplying total monthly revenue by 0.60. Since fixed payroll is $34,583, this variable cost defintely dictates how much revenue you need just to cover fixed overhead.
Input: Monthly Revenue × 0.60
Covers: Fuel, tolls, trailer wear
Budget impact: High initial drag
Cutting Travel Spend
Optimize routes to reduce the 60% fuel burn. Grouping multiple client training sessions geographically cuts down redundant travel days. A common mistake is accepting single-client jobs far from your base that don't cover the trip cost effectively.
Stack training cohorts by region
Prioritize high-density zip codes
Negotiate volume discounts on fuel
Margin Reality
With 60% going to fuel, your contribution margin before fixed costs is only 40% of revenue. This is very thin for a service business. This structure demands high volume or premium pricing to cover the substantial fixed base, including $1,800 in vehicle maintenance.
Running Cost 7
: Software and Compliance
Fixed Software Overhead
Your essential software and compliance tools cost a fixed $1,150 per month right now. This covers the Customer Relationship Management (CRM) system, necessary certification tracking software, and basic office administration functions. This spend is a baseline requirement for tracking client data and proving regulatory adherence.
Cost Components Explained
This $1,150 covers the digital infrastructure needed to manage client relationships and certification status. Inputs needed are the number of active trainees for licensing fees and the complexity of compliance reporting required by OSHA. This fixed cost is small compared to the $34,583 payroll but is critical for operational integrity.
CRM for client history.
Software for certification status.
Office admin support tools.
Managing Software Spend
Avoid paying for features you won't use in your CRM; focus only on core data tracking. Since compliance is high-stakes, don't cut the certification platform, but you can defintely audit admin tools yearly. Look for bundled pricing instead of separate vendor contracts to save cash.
Audit software seats quarterly.
Bundle CRM and compliance tools.
Avoid premium support tiers.
Compliance as Insurance
Treat this $1,150 overhead as essential insurance against massive regulatory fines, not just an administrative expense. As your training volume increases, map out the exact point where your current certification software tier becomes inefficient. Staying compliant protects your high-value contracts.
