Which expenses are fixed and which move with sales in an energy audit business?

Cost classification

Break-even is reliable only when job-linked spend stays out of overhead. In the first year, third-party assessments, software licenses, commissions, and travel reduce contribution before fixed monthly bills and staffing are covered.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Include $3,500/month in fixed overhead for the full Month 1 to Month 60 planning range.	Spreading rent across jobs and hiding true monthly burn.
General Software Subscriptions	Fixed	Include $300/month as recurring overhead before calculating required contribution margin.	Treating general subscriptions like usage-based delivery spend.
Third-Party Technical Assessment Costs	Variable	Deduct 8.0% of first-year revenue before measuring break-even contribution.	Treating technical assessments as overhead instead of job-linked spend.
Specialized Software Licenses	Variable	Deduct 4.0% of first-year revenue as service delivery expense tied to audit volume.	Putting delivery software below the break-even line.
Sales Commissions	Variable	Deduct 7.0% of first-year revenue because commission expense rises with closed sales.	Classifying commissions as fixed sales payroll.
On-site Travel & Logistics	Variable	Deduct 5.0% of first-year revenue since site visits increase with audit jobs.	Treating travel as overhead instead of job-linked spend.
Energy Auditor Staffing	Semi-fixed	Model in staffing steps, starting at 0.5 FTE in the first year and rising as capacity needs grow.	Assuming labor scales smoothly with every new audit.
Online Marketing Budget	Semi-variable	Model the $20,000 first-year budget with $1,000 CAC to test lead volume and sales efficiency.	Treating all marketing as fixed even when CAC changes with acquisition volume.

How does break-even change from a lean startup team to a full-capacity Energy Audit business?

Scenario table

Lean is still below break-even, base is close to flat, and full capacity gives a clear cushion. As the team expands, revenue grows faster than variable cost, but fixed overhead rises too, so the mix has to improve.

Planning case only; actual results will move with client mix, pricing, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean startup team	$19.5k	$4.7k	$26.1k	76%	-$11.2k	Still below break-even, so use it for validation.
Base Year 2 team	$54.8k	$12.1k	$40.5k	78%	$2.2k	Near break-even, with only a small monthly cushion.
Full-capacity Year 3 team	$108.9k	$21.8k	$59.6k	80%	$27.6k	Comfortably above break-even and better for wider reach.

What breaks the break-even plan for this energy audit service?

Stress test

The plan is tight in Year 1: about $19,500/month of revenue against a $34,300 break-even point. If bookings soften, travel creeps above 5% of revenue, or hiring starts early, the gap widens fast and Month 19 gets shaky.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$34,300	$14,800 gap	Year 1 revenue is already below break-even.
Revenue shortfall	Year 1 revenue stays near $19,500/month as lead flow lags.	$34,300	$14,800 gap	Soft bookings leave no cushion for fixed payroll.
Fixed-cost increase	Add $1,000/month of overhead.	$35,616	$16,116 gap	Every extra fixed dollar moves break-even up fast.
Margin pressure	Variable expenses rise from 24% to 30% of revenue.	$37,240	$17,740 gap	Travel, commissions, and discounts push margin down.
Combined pressure	Lead flow softens, travel runs above 5% of revenue, and variable expenses rise to 30%.	$38,668	$19,168 gap	This can push the plan past Month 19.

Founder checklist

The model reaches break-even in Month 19 and needs about $34,300 in monthly revenue, but it also shows a $620,000 cash trough. Before you commit to rent, hires, and equipment, prove the pipeline, prices, and travel math can carry that load.

1Demand proof$34.3K/mo

Verify the pipeline can support that monthly run rate and keep Year 1 CAC near $1,000, or the break-even target is not real.

2Lease load$6.1K/mo

Keep the fixed base lean, since office rent is $3,500 of the $6,050 monthly overhead and should wait until demand is steady.

3Price stack$960-$10.8K

Confirm the model prices hold at $960 Basic, $3,000 Standard, $10,800 Investment, $1,700 Consulting Retainer, and $700 Verification Service.

4Margin mix76% CM

Check that third-party assessment, software, sales commissions, and travel still leave about 76% contribution margin, with travel capped below 5% of revenue.

5Staff ramp2.5 FTE

Delay Month 13 hires until the founder, half-time auditor, sales, and admin capacity are fully used, so payroll grows with real utilization.

6Cash cushion$620K

Hold enough cash to fund the $133,000 capex plan and the Month 19 cash trough before break-even starts paying back.
