Cost classification

Break-even is only useful if fixed overhead and job-linked costs are separated. Here, rent, payroll, and planned marketing set the monthly hurdle, while subcontractors, travel, and tool percentages reduce contribution margin.

Expense	Cost	Break-Even Treatment	Common Mistake
Office rent	Fixed	Carry $3,500/month in fixed overhead until the office footprint changes.	Allocating rent to each audit and overstating job margin.
Core first-year payroll	Fixed	Use about $22.9k/month: ($150,000 + $80,000 + $45,000) / 12.	Treating salaried consultants as variable labor.
Marketing budget	Fixed	Use $50,000/year, or about $4.2k/month, as planned demand-generation overhead.	Modeling CAC but forgetting the monthly cash spend.
Subcontractor fees	Variable	Deduct 7% of revenue before covering fixed overhead.	Putting subcontract support into fixed overhead.
Client project travel	Variable	Deduct 4% of revenue for site visits and fieldwork.	Treating travel-heavy fieldwork as fixed.
AI analytics platform licensing	Variable	Deduct 8% of revenue in the first year.	Calling percentage-based software a fixed subscription.
Specialized audit tool costs	Variable	Deduct 5% of revenue for audit tools tied to delivery volume.	Treating rented or usage-based diagnostic tools as fixed overhead.
Energy Auditor capacity increases	Semi-fixed	Add salary blocks when staffing steps up, such as moving from 1.0 to 1.5 FTE in the second year.	Spreading future hires evenly across every current job.

How do lean, base, and full operating models change break-even for an energy efficiency consulting firm?

Scenario table

Break-even shifts with payroll, marketing, and travel. The lean model clears the line with less revenue, while the full model needs more monthly sales because staff depth and delivery costs rise.

Planning assumptions only; actual break-even will move with client mix, travel load, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean solo consulting model	$25,000	$6,000	$19,000	76%	$0	Lowest fixed load, so audit work must stay steady.
Base staffed launch	$36,417	$8,740	$27,667	76%	$0	More service depth, but it still needs consistent client flow.
Full growth model	$65,083	$11,715	$53,333	82%	$0	Higher payroll needs more volume, even with a stronger margin mix.

What breaks the break-even plan for this energy efficiency consulting business?

Stress test

Base case is near break-even, so a 10% revenue dip or a 5-point margin hit can flip it into loss. Fewer audits, longer travel, and higher subcontractor or software costs are the main tripwires.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$437K	$0 cushion	The cushion is thin, so small misses matter.
Revenue shortfall	Revenue falls 10% to $393K.	$437K	$44K gap	Slower close rates wipe out the cushion.
Fixed-cost increase	Fixed costs rise 10% to $365K.	$480K	$43K gap	Insurance, software, or payroll creep raises the bar.
Margin pressure	Variable expense rises 5 points, cutting margin to 71%.	$468K	$31K gap	Subcontractor fees and travel eat the spread.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and margin drops to 71%.	$514K	$121K gap	That mix can turn a near-breakeven plan into a loss.

What should you verify before signing office space and buying field gear for energy efficiency consulting?

Founder checklist

Test the offer mix against break-even before you lock in rent, hires, or equipment. The model only holds if audit, advisory, and oversight pricing clears direct costs, and if lead flow can reach about 9 clients a month without pushing cash below the $837K reserve.

1Pricing stack$5.0K / $900 / $2.0K

Verify audit, advisory, and project oversight pricing at 20, 5, and 10 billable hours before you sign a lease.

2Direct margin76% CM

Keep Year 1 direct costs near 24% of revenue, with 8% licensing, 5% audit tools, 7% subcontractors, and 4% travel, or break-even slips.

3Fixed base$6.1K/mo

This load includes $3,500 rent, $300 insurance, and $400 training, so wait on the lease until booked work can carry it.

4Demand run-rate9 clients/mo

Prove you can book about 9 clients a month, cap travel radius before the 4% travel line gets too low, and delay the vehicle, diagnostic gear, and platform build if lead flow is weak.

5Staffing rampMonth 13

Delay the sales manager, assistant, and later junior consultant until recurring work supports them, not before.

6Cash cushion$837K

Hold this reserve because minimum cash lands in Month 2, payback takes 8 months, and one-time capex should stay separate from monthly break-even burn.
