Running Cost 1
: Payroll and Benefits
Biggest Fixed Cost
Payroll for your initial team of five FTEs is your primary fixed drain in 2026. This base salary commitment hits $27,167 monthly before you add in required payroll taxes or employee benefits packages. This number sets the baseline for your monthly operating expenses and is the anchor point for all profitability planning.
Staffing Budget Input
This $27,167 covers only the base wages for the five full-time equivalents needed to run operations in 2026. You must add estimates for the employer share of payroll taxes (like FICA) and any planned benefits, like health insurance or 401(k) matching. This cost is static, meaning it doesn't change if you land zero jobs that month.
Base wages for 5 FTEs only.
Excludes employer tax burden.
Fixed monthly drain.
Controlling Headcount
Managing this high fixed cost requires strict control over hiring pace relative to confirmed revenue generation. Avoid hiring ahead of project backlogs, especially for non-billable roles. A common mistake is assuming 100% utilization for specialized application crews; you'll defintely see downtime.
Hire only against confirmed work.
Use contractors for utilization spikes.
Watch utilization rates closely.
Break-Even Anchor
Since payroll is the largest fixed cost at $27,167, it dictates your minimum monthly revenue target. You need enough gross profit from billable hours and materials to cover this amount plus rent ($4,200) and insurance ($1,500) just to keep the core team paid and the lights on.
Running Cost 2
: Warehouse and Office Rent
Fixed Space Cost
Your base operating overhead is set immediately because warehouse and office rent is a fixed $4,200 per month. This cost hits your Profit and Loss (P&L) statement before the first job is even invoiced. You need revenue to cover this baseline spend right away.
Rent Budget Input
This $4,200 monthly covers your physical footprint-the warehouse for chemical storage and the small office for admin work. It is a fixed expense, unlike variable costs like abrasives (which are 220% of revenue). To model this, you just input the $4,200 figure for every month in your 2026 projections.
Fixed cost: $4,200/month.
Covers warehouse and office space.
Needed before first revenue arrives.
Managing Fixed Space
Since rent is fixed, the only way to reduce its impact is to maximize revenue density per square foot. Don't pay for space you don't use, especially early on. A common mistake is signing a long lease based on 2027 projections, not 2026 reality. Maybe consider a shared industrial space initially.
Avoid long-term leases early.
Maximize revenue per square foot.
Keep office space lean, perhaps virtual.
Overhead Lock-In
This $4,200 rent commitment means you must generate enough gross profit just to cover space and payroll before paying for marketing or equipment fuel. If your five FTEs cost $27,167, your baseline fixed burn rate is over $31k monthly. You defintely need strong early project pipeline visibility.
Running Cost 3
: Chemicals and Abrasives (COGS)
Material Cost Overload
Material costs are crippling profitability projections right now. In 2026, chemical densifiers at 140% of revenue and grinding abrasives at 80% of revenue combine to hit 220% of total revenue. This cost structure means you lose $1.20 for every dollar earned before factoring in payroll or rent.
Material Cost Drivers
This cost covers the core consumable inputs for the surface treatment service. The projection uses 140% of revenue for chemical densifiers and 80% of revenue for grinding abrasives. This 220% total is based on 2026 revenue estimates. You must verify these material usage rates against actual project scope and application needs.
Densifiers: 140% of Revenue
Abrasives: 80% of Revenue
Total Material COGS: 220%
Cutting Material Waste
You can't sustain 220% material costs; that's the main takeaway. Focus on vendor negotiation for bulk pricing on both chemicals and abrasive pads. Standardize application processes immediately to reduce over-application, which inflates chemical use. Aim to bring this ratio below 100% before starting operations.
Negotiate bulk chemical pricing now.
Standardize application rates per square foot.
Audit abrasive pad consumption rates closely.
Pricing Reality Check
A 220% material cost structure is a non-starter for any service business. Your current revenue model, based on billable hours plus materials, won't cover fixed costs like the $27,167 monthly payroll. You must re-engineer pricing or secure supplier contracts drastically reducing these input costs, or you'll defintely fail.
Running Cost 4
: Vehicle Leases and Fuel
Vehicle Cost Structure
Vehicle costs are a major fixed and variable drain on your business model. You face $2,800 monthly in fixed leases and insurance, plus 40% of revenue goes straight to fuel and equipment upkeep. This variable burn rate means revenue growth must outpace operational costs fast to maintain profitability.
Cost Inputs
This cost covers truck leases, necessary commercial insurance, and the fuel/maintenance budget for application equipment. To forecast accurately, you need firm quotes for three fleet vehicles and the projected revenue run rate to calculate the 40% variable portion. It's a significant, non-negotiable part of your initial operating overhead.
Lease/Insurance: $2,800 fixed monthly
Fuel/Maintenance: 40% of gross revenue
Input needed: Fleet quotes
Cost Management
Managing the 40% variable cost is critical since it scales directly with every job you complete. Focus on optimizing route density to cut fuel use per square foot treated. Also, negotiate better fleet insurance rates based on your company's safety record. Small reductions here directly improve your gross margin.
Prioritize route efficiency
Shop insurance annually
Benchmark fuel cost per mile
Pricing Impact
Because 40% of revenue is tied to variable equipment costs, your project pricing must reflect this heavy operational load. If your average job size doesn't cover this burn, you'll defintely struggle to cover the fixed $2,800 lease payment every month.
Running Cost 5
: Liability and Compliance Fees
Fixed Compliance Spend
Liability and compliance costs total $1,500 per month for this operation. This covers mandatory commercial insurance and essential safety training for the crew. This is a non-negotiable fixed overhead you must cover every month before revenue starts flowing.
Compliance Cost Inputs
This $1,500 monthly expense is split between two fixed buckets. Commercial liability insurance runs $1,100, protecting against job site incidents. The remaining $400 covers required safety training, which is crucial given the chemical application work. This cost is independent of project volume.
Insurance: $1,100 monthly fixed fee.
Training: $400 monthly fixed fee.
Total: $1,500 monthly overhead.
Managing Liability Spend
Since the insurance premium is fixed, focus on reducing training variability. Regularly audit training providers to ensure you aren't overpaying for standard certifications. High turnover will inflate the $400 monthly training budget quickly. Defintely shop your insurance policy annually.
Audit training vendors annually.
Ensure coverage matches exposure.
Keep employee turnover low.
Fixed Overhead Anchor
At $1,500 per month, liability and compliance set the absolute minimum fixed cost floor for operations. If payroll is $27,167 and rent is $4,200, this fee adds another 4.5% to your base fixed overhead before you even buy chemicals or fuel.
Running Cost 6
: Customer Acquisition Costs
CAC Target Set
Your 2026 marketing plan budgets $25,000 annually, assuming you can land each new commercial client for $850. This Customer Acquisition Cost (CAC) is high for B2B industrial services, so you need significant lifetime value to justify the spend.
Budgeted Client Count
CAC is what you spend to land one paying client. For 2026, the $25,000 marketing spend divided by the target $850 CAC means you expect to sign about 29 new clients. This estimate only uses the marketing line item, ignoring internal sales salaries or overhead. Here's the quick math: 25,000 divided by 850 equals 29.4 clients.
Annual Marketing Budget: $25,000
Target CAC: $850
Expected New Clients: 29
Managing High Acquisition Cost
An $850 CAC for industrial flooring is steep unless the average project value is substantial. You must track the payback period-how long it takes for a client's revenue to cover that initial acquisition cost. Focus on getting existing clients to refer new warehouses, as referral costs are near zero.
Prioritize direct outreach to facility managers.
Measure payback period against project size.
Use client success stories for lead generation.
Profitability Checkpoint
If your first project revenue doesn't quickly recover that $850 cost, you'll need far more than 29 clients to cover the $27,167 monthly payroll. What this estimate hides is the cost of sales time, so track lead conversion rates closely.
Running Cost 7
: Accounting and Utilities
Admin Overhead Baseline
Your baseline administrative overhead for accounting, legal, utilities, and communications is a fixed $1,200 monthly. This $650 for professional services and $550 for operational utilities must be covered before you make a dime on a job. It's essential tracking for any breakeven calculation.
Cost Components
This $1,200 covers non-direct operational costs needed to stay compliant and running. The $650 component covers accounting software and legal retainer fees, while the $550 covers power and phone services for your office. These are fixed costs that don't scale with project volume.
Accounting/Legal: $650 monthly.
Utilities/Comms: $550 monthly.
Total overhead: $1,200 fixed.
Managing Fixed Spend
Managing these fixed G&A (General and Administrative) costs requires diligence, especially when revenue is low. Don't let legal fees balloon due to reactive work; use a fixed monthly retainer instead of hourly billing where possible. You defintely want to audit utility usage quarterly.
Audit utility bills yearly.
Negotiate fixed legal retainers.
Bundle communications services.
Overhead Leverage
Since this $1,200 is fixed, every dollar of revenue above your gross profit margin directly reduces this burden on a percentage basis. If your gross margin is 50%, you need $2,400 in monthly revenue just to cover this overhead and your direct job costs.
Monthly running costs average $51,700 in 2026, with fixed overhead (excluding payroll) totaling $9,700 and variable costs consuming 29% of revenue
The model projects break-even in September 2026 (nine months), but you must secure $713,000 in minimum cash to cover the initial ramp-up
