Which expenses stay fixed and which move with sales in a construction safety consulting break-even model?

Cost classification

Break-even gets unreliable when travel, commissions, and project tech are treated like overhead. Classify each expense by how it behaves, so the model doesn’t overstate margin as site work grows.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $3,500 per month in fixed overhead for the current office capacity.	Spreading rent across jobs and making margin look lower than it is.
Professional Liability Insurance	Fixed	Use $1,200 per month as recurring fixed overhead during the planning range.	Treating insurance as project labor instead of baseline risk coverage.
General Business Software	Fixed	Use $400 per month in fixed overhead unless seats rise with headcount.	Ignoring seat growth when staff additions change the monthly bill.
Project-Specific Travel & Site Visits	Variable	Model at 8.0% of revenue in the first year because it rises with site work.	Treating travel as fixed hides weak site-level margins.
Sales Commissions & Bonuses	Variable	Model at 7.0% of revenue in the first year because payouts follow sales volume.	Leaving commissions below the break-even line and overstating contribution margin.
Specialized Software Licensing	Semi-variable	Model at 6.0% of revenue in the first year, with usage falling to 4.0% by the mature year.	Treating all licensing as fixed when project usage drives part of the bill.
Direct Project Technology Costs	Semi-variable	Model at 4.0% of revenue in the first year, declining to 3.0% by the mature year.	Folding client-specific tech into general overhead and overstating job margin.
Safety Professional Staffing	Semi-fixed	Step up salary capacity as the team grows, including senior roles at $120,000 per FTE.	Assuming labor scales smoothly when added staff arrive in hiring blocks.

How does break-even change from a lean solo setup to a staffed, full-service consulting model?

Scenario table

Break-even moves up fast as the team grows. The lean setup clears at about $26.7k a month, the base case needs $52.8k, and the full-service case needs $74.1k; recurring retainers help, but payroll still drives the bar.

Planning figures only; real break-even will shift with sales, booked hours, and travel.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean solo consulting setup	$26.7k	$6.7k	$20.0k	75.0%	$0	Low fixed load keeps the hurdle manageable.
Base staffed consulting model	$52.8k	$13.2k	$39.6k	75.0%	$0	Added headcount raises the monthly hurdle fast.
Full-service Year 2 model	$74.1k	$17.3k	$56.8k	76.7%	$0	Higher margin helps, but the larger team still needs steady retained work.

What breaks the break-even plan for construction safety consulting?

Stress test

Break-even gets fragile fast if sales slip or field costs rise. At $633,000 of revenue against $475,000 of fixed costs and 25% variable expenses, a 10% revenue drop or a 10% fixed-cost jump pushes the plan into the red.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base case.	$633,000	$0 cushion	The plan clears break-even only if revenue holds.
Revenue shortfall	Revenue falls 10% while costs stay flat.	$633,000	$63,000 gap	A modest sales miss removes the cushion.
Fixed-cost pressure	Fixed costs rise 10%.	$696,000	$63,000 gap	Overhead growth needs matching sales.
Margin pressure	Variable expenses rise from 25% to 30%.	$679,000	$46,000 gap	Travel-heavy jobs and subcontractor costs can squeeze margin.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and variable expenses rise to 30%.	$746,000	$176,000 gap	Stacked pressure breaks the base plan fast.

Is your construction safety consulting pipeline ready before you lock in office space, hires, and paid capacity?

Founder checklist

Don’t add office space, vehicles, or full-time hires until you’ve got signed or late-stage work near $633K a month and the staffing plan can deliver it at the quoted rates. The model only breaks even by Month 34, so early fixed spend has to earn its keep fast.

1Pipeline Proof≈$633K/mo

Verify you can point to signed or late-stage work near this run rate before you lease space or add headcount.

2CAC Gate$2.5K CAC

Check that Year 1 client acquisition stays near $2,500 each, because the $25,000 launch budget only buys 10 wins at that cost.

3Fixed Burn$45.4K/mo

Keep Year 1 payroll plus rent, insurance, software, and admin near $45.4K a month before you commit to office space or vehicles.

4Margin Floor75% CM

After software, tech, travel, and sales comp, about 75 cents of each revenue dollar is left before payroll and rent, so pricing must stay above that floor.

5Capacity Ramp47 hrs

Verify the team can cover the 47 billable hours in the current offer mix, and hold the Month 7 junior hire and Month 13 analyst until those hours are repeatable.

6Cash Trough-$371K

The model's lowest cash point is -$371K in Month 39, and the $101K opening capex sits inside that risk, so delay hires if utilization lags and protect the buffer before you spend.
