Fixed overhead totals $307,000 annually.
Estimated wages account for $755,000.
These are costs you pay regardless of project volume.
This base spend is $1.062 million before any materials or labor tied directly to jobs.
Variable Cost Impact
Variable costs run at 30% of projected revenue.
Based on $147 million revenue, VC hits $44.1 million.
This percentage covers direct costs like materials and subcontractor fees.
The high variable rate means operational efficiency is key to margin protection.
Which recurring cost category represents the largest monthly outlay?

Key Takeaways
A minimum cash buffer of $228,000 is required to sustain operations until the projected nine-month break-even point in September 2026.
Total monthly operating costs, excluding variable project expenses, are projected to start near $98,500 in 2026.
Payroll for the initial seven full-time employees constitutes the largest recurring monthly outlay, totaling approximately $62,917.
Fixed overhead costs are set at $25,600 monthly, which must be quickly covered by scaling volume to offset the high $15,000 Customer Acquisition Cost.
Running Cost 1
: Wages and Salaries
Initial Payroll Commitment
Your starting team of 7 full-time employees (FTEs), covering critical roles like engineers and foremen, sets your baseline payroll expense. This core team requires approximately $62,917 per month just for salaries. Remember, this figure excludes the real cost of benefits and payroll taxes, which you must budget for separately. That's a heavy initial fixed cost.
Staffing Cost Drivers
This $62,917 monthly payroll is based on the salaries for 7 specific roles: engineers and foremen. To calculate this, you need the agreed-upon gross salary for each of those 7 hires, summed up monthly. This cost is fixed until you hire more staff or adjust compensation. It anchors your monthly operating budget right away.
7 FTEs total headcount.
Engineers and foremen roles.
Salaries before taxes/benefits.
Managing Staff Burn Rate
Managing this fixed payroll means optimizing utilization immediately. If these 7 people aren't billed out, that $62,917 burns cash fast. Avoid premature hiring; use contractors for specialized, short-term needs until project flow is certain. Don't defintely over-staff the initial engineering team.
Billable utilization is key.
Use contractors strategically.
Delay hiring non-essential roles.
Break-Even Dependency
Since this $62,917 is a fixed monthly drain before rent or materials, your first few projects must generate substantial gross profit quickly. This payroll dictates the minimum revenue required just to keep the lights on and the core team working. Every day without a signed contract increases the cash runway needed.
Running Cost 2
: Facility Lease
Lease Commitment
Your physical footprint starts costing $12,500 monthly on January 1, 2026. This fixed lease covers the regional warehouse and office needed for design planning and administrative overhead. You must budget this expense immediately, as it is not tied to project revenue.
Cost Inputs
This $12,500 covers the essential regional space for your specialized construction business. Inputs needed are the lease start date (Jan 1, 2026) and the fixed monthly rate. It sits alongside other fixed costs like $62,917 in payroll and $4,500 in professional insurance.
Fixed cost starts Jan 1, 2026.
Covers warehouse/office needs.
Budget $150,000 annually.
Space Optimization
Since this is a fixed lease, reducing it requires negotiation or finding smaller space. A common mistake is over-committing to square footage too early. If you can run design from a temporary, smaller office for the first six months, you might save $75,000 before the main lease kicks in.
Negotiate lease term lengths.
Avoid paying for excess storage.
Check exit clauses carefuly.
Cash Flow Impact
Understand that this lease is a hurdle before revenue starts flowing, given the Jan 1, 2026 start date. It directly impacts your initial cash runway calculation alongside payroll. If you delay site selection past Q3 2025, you risk operational delays or paying premium rates for quick occupancy.
Running Cost 3
: HVAC/HEPA Materials
Material Cost Crisis
Specialized HVAC and HEPA Materials are the single biggest threat to profitability for your negative pressure room installations. In 2026, these component costs alone hit 180% of project revenue. This cost structure guarantees negative gross margins unless immediate pricing or procurement changes are made.
Input Tracking
This 180% variable cost covers all high-efficiency particulate air (HEPA) filters, specialized ductwork, and pressure control units needed for compliance. You must track material costs against the specific scope defined in the contract. If your average project revenue is $100k, materials cost $180k. That's the starting reality.
Track quotes by specific room type
Monitor lead times closely
Factor in 50% of revenue for fleet/travel
Sourcing Tactics
You can't cut quality here, but you can manage sourcing aggressively. Focus on securing volume discounts with two primary suppliers, not just one. Also, negotiate longer payment terms to ease working capital strain. If onboarding takes 14+ days, churn risk rises because suppliers might defintely delay critical shipments.
Target 15% material cost reduction
Negotiate 60-day payment windows
Avoid rush ordering fees
Pricing Mandate
Pricing models must immediately reflect this material burden. If you cannot secure supply contracts that drop this figure below 100% of revenue by Q3 2026, you need to halt sales expansion. This isn't a scalable model; it's a guaranteed cash drain.
Running Cost 4
: Professional Insurance
Mandatory Liability Cost
Your professional liability coverage costs a fixed $4,500 monthly, which you must budget for immediately. This insurance protects against claims arising from your specialized engineering and construction services related to airborne infection isolation rooms. It's a baseline requirement before you sign your first contract.
Insurance Cost Structure
This $4,500 premium is a fixed monthly expense, not tied to project volume or revenue. You need to confirm the required limits based on the scale of hospital contracts you target. It sits alongside $1,800 for software and $2,500 for training as essential non-payroll fixed overhead.
Covers high-risk engineering errors.
Fixed at $4,500 per month.
Mandatory for healthcare compliance.
Controlling Fixed Risk
You can't cut this cost much, but securing multi-year policies might yield a small discount, maybe 3% to 5% annually. The bigger risk is underinsuring; if you land a large hospital job, insufficient coverage exposes you to massive liability, dwarfing any small premium savings you might chase.
Avoid dropping coverage mid-project.
Shop quotes annually for better rates.
Ensure limits match contract size.
Fixed Cost Impact
This $4,500 insurance cost adds to your $12,500 lease and $4,300 software/training total fixed base before payroll. If you aim for $100k in monthly revenue, this insurance is just 4.5% of that target. However, if revenue is low, this fixed burden eats into your contribution margin fast.
Running Cost 5
: Customer Acquisition
Acquisition Volume Limit
Your $120,000 marketing budget for 2026 only supports 8 new clients given the high $15,000 Customer Acquisition Cost (CAC). You must secure high contract values quickly, or you're not going to see meaningful scale from this spend.
Cost Breakdown
The $120,000 marketing spend targets specialized healthcare facilities needing Airborne Infection Isolation (AII) rooms. To cover this, you need to calculate how many projects you must close. Here's the quick math: $120,000 budget divided by a $15,000 CAC equals 8 potential new contracts.
Budget covers all 2026 marketing outreach.
CAC assumes $15,000 per hospital contract.
This volume is low for covering high fixed costs.
Lowering Acquisition Cost
Reducing a $15,000 CAC requires tightening the sales pipeline, not just cutting ad spend. Since this is high-value construction, focus on direct outreach and compliance consulting partnerships. Avoid long qualification periods, which defintely inflate costs.
Focus on direct relationship selling to facility heads.
Use existing project success for strong referrals.
This acquisition spend is risky because specialized HVAC/HEPA material costs run at 180% of project revenue. If you only acquire 8 clients, the high fixed overhead-like the $62,917 monthly payroll-will quickly overwhelm cash flow before revenue stabilizes.
Running Cost 6
: Fleet and Travel
Fleet Cost Structure
Fleet costs are split: a fixed $3,200 monthly for maintenance and fuel, plus a massive variable component. Travel and logistics immediately consume 50% of revenue on every job. This high variable load means project pricing must aggressively cover logistics before hitting overhead.
Cost Breakdown
The $3,200 monthly covers baseline fleet upkeep and fuel for company vehicles used across various sites. The major concern is the 50% variable expense for project logistics, which requires detailed revenue forecasting to model accurately. What this estimate hides is the utilization rate of the fleet.
Fixed cost: $3,200/month.
Variable cost: 50% of revenue.
Need accurate revenue targets.
Optimization Tactics
Cutting 50% of revenue is tough, but optimizing travel routes reduces fuel burn and time. Focus on securing dense project clusters within specific geographic zones to lower logistics trips. Avoid the common mistake of treating travel as a sunk cost; it's a direct margin killer. You defintely need high initial project pricing.
Improve route density per zip code.
Negotiate bulk fuel contracts.
Benchmark logistics against industry peers.
Margin Reality Check
Because logistics eats half your revenue, your gross margin needs to be substantially higher than normal construction work. If your material cost is 180% of revenue, you must price projects to cover that material spend, plus the 50% variable travel hit, before you even touch fixed overhead.
Running Cost 7
: Software and Training
Software & Training Fixed Spend
Software and training set a baseline fixed overhead of $4,300 monthly, separate from payroll. This covers essential design tools and mandatory compliance upkeep for specialized construction work. You need this spend locked in before the first project starts.
Cost Breakdown
This $4,300 covers two distinct operational needs for AeroMed Constructors. The $1,800 is for Computer-Aided Design (CAD) and Project Management Software needed for engineering plans. The remaining $2,500 funds Ongoing Certification Training, which is critical for maintaining compliance with health standards.
CAD/PM Software: $1,800/month
Certification Training: $2,500/month
Total fixed cost: $4,300
Managing Compliance Spend
Training costs are largely non-negotiable; compliance is key for airborne infection isolation rooms. For software, check if the CAD platform offers volume discounts if you scale past your initial seven FTE team members. Avoid paying for unused licenses, especially in the first six months while ramping up.
Bundle software subscriptions now
Audit training needs quarterly
Negotiate annual training contracts
Fixed Overhead Context
At $4,300 monthly, this cost represents about 20% of your minimum non-salary fixed overhead base, which is $21,300 before payroll. If you land only one small project in Q1 2026, this fixed spend hits your cash flow hard. You need revenue flowing defintely fast.
The financial model shows you need a minimum cash buffer of $228,000 by August 2026 to manage negative cash flow before achieving profitability Breakeven is projected for September 2026, which is 9 months after launch
The Customer Acquisition Cost (CAC) starts high at $15,000 in 2026 but is forecasted to drop to $12,500 in 2027 as operational efficiency improves
Variable costs total 30% of revenue in 2026 The largest component is Specialized HVAC and HEPA Materials at 180% of revenue, plus 40% for compliance certifications
Total fixed operating expenses are $25,600 per month, covering the $12,500 lease, $4,500 insurance, and $3,200 fleet costs
