Running Cost 1 : Specialized Staff Payroll
2026 Headcount Cost
Your 2026 payroll budget for 65 full-time employees (FTEs) is set at $767,500 annually. This figure covers critical leadership roles, specifically the $180,000 salary for the CEO and $180,000 combined for the two Drilling Crew Leads. This is a major fixed operating expense you must cover before revenue hits.
Payroll Inputs
This $767,500 payroll estimate for 65 FTEs must account for more than just base salaries; it needs employer payroll taxes, health insurance contributions, and 401(k) matching. The known inputs are the $180k CEO salary and $90k per Drilling Crew Lead. We need the average loaded rate for the other 62 staff to verify accuracy.
- Total FTEs: 65
- CEO Cost: $180,000
- Lead Cost: $180,000 total
Managing Labor Spend
Managing specialized labor cost hinges on controlling the loaded rate (salary plus benefits/taxes). Since drilling expertise is scarce, focus on retention to avoid high replacement costs. If onboarding takes 14+ days, churn risk rises defintely. Keep the ratio of high-cost staff (like the Leads) efficient relative to project volume.
- Benchmark loaded rates against industry peers.
- Tie bonuses to project profitability, not just utilization.
- Avoid unnecessary overtime accrual.
Payroll as Fixed Cost
Staff payroll is largely a fixed operating expense until you scale headcount significantly. With 65 people budgeted, this $767.5k annual cost must be covered every month, regardless of project flow. This means your break-even point is heavily influenced by how quickly you can fill those 65 roles with billable work.
Running Cost 2 : Office & Facility Rent
Fixed Overhead Snapshot
Fixed overhead for EarthCore Geothermal is set at $23,800 monthly, dominated by real estate and necessary risk coverage. You must cover $8,500 in rent plus $4,000 for specialized insurance before earning a dime.
Fixed Overhead Components
This $23,800 monthly overhead is your starting point before any drilling project revenue arrives. The $8,500 Office Rent covers the physical space for administration. You also budget $4,000 monthly for specialized Insurance, specifically General Liability and Equipment coverage, which is non-negotiable for this industry. Honestly, this fixed base is substantial.
- Rent: $8,500/month
- Specialized Insurance: $4,000/month
- Remaining Fixed Costs: $11,300
Managing Facility Costs
Rent is tough to cut once signed, so negotiate lease terms carefully, perhaps opting for shorter initial commitments. Review the $4,000 insurance allocation annually; ensure deductibles align with your cash reserves to lower the premium. Don't pay for more square footage than the 65 FTEs actually need right now.
- Negotiate shorter initial lease terms.
- Shop specialized insurance quotes aggressively.
- Ensure space matches current headcount needs.
Overhead vs. Payroll
This $23,800 fixed overhead sits on top of the $767,500 annual payroll budget. You need significant project volume just to cover these structural costs before factoring in the huge 160% COGS from materials and equipment rental.
Running Cost 3 : Materials & Consumables
High COGS Hurdle
Materials and consumables represent a massive 160% of revenue in 2026, showing immediate negative gross margin. Focus on procurement efficiency now because this COGS element defines your early viability, even as it should improve to 140% by 2030.
Cost Inputs Needed
This Cost of Goods Sold (COGS) category covers all physical items consumed during drilling, like specialized drill bits, casing, and drilling fluids. Since this cost is 160% of revenue in 2026, you need precise tracking of material usage per foot drilled. Honestly, you need quotes based on projected annual volume, not just single-job pricing.
- Track consumption per project foot.
- Material costs drive initial margin.
- Need volume discounts early.
Optimizing Materials Spend
Getting materials below 100% of revenue is the main goal, but the immediate target is hitting the 140% benchmark by 2030. Negotiate bulk pricing based on projected yearly needs, not just current project needs. Avoid paying for expedited shipping, which destroys margins fast.
- Standardize material specs across projects.
- Lock in supplier contracts now.
- Minimize on-site material waste.
Margin Reality Check
With consumables at 160% of revenue, your gross margin is negative before considering fixed overheads like payroll ($767,500 in 2026) or rent ($23,800 monthly). Every dollar earned is currently spent on materials plus 60 cents more, making operational efficiency paramount for survival.
Running Cost 4 : Direct Equipment Rental
Rental Cost Target
Direct equipment rental is a major variable cost eating 60% of revenue in 2026. Your primary operational focus must be aggressively driving this down to 40% by 2030 to secure profitability in this high-touch service. This cost directly scales with every drilling job you complete.
Cost Input Factors
This cost covers heavy machinery needed for drilling, like specialized rigs and earth movers, classified as variable Cost of Goods Sold (COGS). You must track this as a percentage of gross revenue, not fixed overhead. If revenue hits $10M in 2026, you're defintely looking at $6M spent just on rentals.
- Track as percentage of revenue.
- Inputs: Rig utilization rate.
- Budget impact: 60% initially.
Optimization Levers
Reducing rental dependency requires strategic fleet planning. Since you use advanced tech from oil and gas, explore phased purchasing over pure rental for high-utilization assets. Avoid long lead times causing emergency, high-rate rentals.
- Negotiate multi-month contracts.
- Benchmark against purchase cost.
- Target 40% by 2030.
Margin Pressure Point
Compare this 60% benchmark against the 160% Materials & Consumables cost. Together, these two variable COGS components dominate your gross margin structure early on. Success depends on negotiating better long-term rental agreements or accelerating asset acquisition timelines faster than projected.
Running Cost 5 : Customer Acquisition
CAC Pressure
Your 2026 customer acquisition plan hinges on managing a very high Customer Acquisition Cost (CAC) of $5,500. With a total marketing budget set at $150,000 annually, you can only afford roughly 27 new customers next year. This low volume means every lead must convert efficiently.
Budget Breakdown
This $150,000 marketing spend is dedicated solely to acquiring customers for deep geothermal drilling projects. A $5,500 CAC reflects the long sales cycle and high-value nature of targeting commercial and industrial facilities. You need precise tracking of marketing spend versus qualified project pipeline generation.
- Covers site assessment marketing.
- Funds specialized lead generation.
- Requires high lifetime value (LTV).
Managing High Cost
Managing this expensive acquisition requires focusing on high-quality referrals and deep industry penetration rather than broad advertising. Since the sales cycle is long, focus on nurturing prospects through the initial site assessment phase. Defintely reduce reliance on paid channels.
- Prioritize industry partnerships.
- Maximize conversion from site visits.
- Track Cost Per Qualified Lead.
LTV Check
Given the $5,500 CAC, your immediate financial focus must be proving the Lifetime Value (LTV) of these few customers exceeds this cost by a factor of three or more. If LTV is low, this acquisition strategy is unsustainable.
Running Cost 6 : Regulatory Compliance
Compliance Cost Structure
Regulatory compliance demands a fixed monthly spend of $6,500, covering essential insurance and professional services. This cost addresses the high liability inherent in deep earth drilling and navigating complex environmental regulations. This is non-negotiable overhead for geothermal work.
Cost Breakdown
Your $6,500 monthly compliance budget splits into $4,000 for specialized insurance and $2,500 for legal and accounting support. This directly covers high-risk liability from drilling operations and adherence to state permitting standards. You need quotes for specialized coverage before signing leases.
- Insurance: $4,000 monthly premium.
- Legal/Accounting: $2,500 monthly retainer.
- Covers deep drilling liability exposure.
Managing Compliance Spend
Reducing this fixed cost risks operational shutdown or massive fines, so focus on efficiency, not cuts. Standardize initial site assessment documentation to reduce billable legal hours, potentially saving 10% on the $2,500 fee. Don't defintely shop around for general liability; you need specialized coverage.
- Standardize initial site assessment reports.
- Bundle legal and accounting services.
- Verify insurance covers specialized drilling equipment.
Pricing Impact
Given the $6,500 monthly spend, your project pricing must capture this cost immediately. This overhead exists before the first foot of earth is drilled. If project acquisition is slow, this compliance burden pressures your initial cash runway significantly.
Running Cost 7 : Fleet & Technology Costs
Fleet & Tech Costs
Fleet and technology costs total $5,800 monthly, split between keeping essential vehicles running and funding future efficiency gains. This recurring spend covers necessary mobility and dedicated research into improving your specialized drilling operations. You need to track the utilization of these assets closely.
Cost Allocation
This $5,800 covers $2,800 for vehicle leases and maintenance, ensuring crews can reach sites like commercial facilities or municipal projects. The remaining $3,000 monthly is an internal allocation for R&D (Research and Development), specifically targeting operational improvements in drilling technology. This is a fixed operational commitment regardless of revenue volume.
Optimization Focus
Since vehicle costs are low compared to Materials & Consumables (160% of revenue), focus optimization on the R&D spend effectiveness. Ensure the $3,000 R&D investment directly targets reducing the high variable costs, like the 60% direct equipment rental rate projected for 2026. If R&D fails to cut rental spend by 2026, this allocation is defintely just overhead.
Tracking R&D Impact
Treat that $3,000 as a project budget, not just a line item. Tie it directly to milestones that reduce the $5,500 Customer Acquisition Cost (CAC) or improve the Materials COGS percentage. If you can’t measure its impact on project throughput or cost per foot drilled, cut it immediately.
