Cost classification

Your break-even number is only useful if fixed overhead, delivery percentages, and staffing steps stay in the right buckets. Put recurring monthly bills, revenue-linked fees, and salary capacity in separate lines before solving for Month 6 break-even.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Include $8,500 per month in fixed overhead from Month 1 through Month 60.	Spreading rent across projects and understating the revenue floor.
Software Subscriptions	Fixed	Include $1,800 per month as operating overhead, separate from project modeling licenses.	Blending subscriptions with usage-based software fees.
Accounting & Legal Services	Fixed	Include $1,500 per month in fixed overhead for recurring back-office support.	Treating recurring admin support as a project-only expense.
CEO / Lead Environmental Consultant salary	Semi-fixed	Model $180,000 annual salary as committed capacity, or $15,000 per month while staffed.	Calling founder labor variable and making break-even look easier.
Senior Environmental Consultant salary	Semi-fixed	Model $120,000 annual salary per FTE; FTE rises from 1.0 in the first year to 5.0 in the fifth year.	Assuming consultant payroll moves smoothly with revenue.
Third-Party Technical Assessment Costs	Variable	Deduct as delivery expense at 8.0% of revenue in the first year, declining to 6.0% by the fifth year.	Leaving outside experts below the gross margin line.
Software Licensing for Environmental Modeling	Variable	Deduct as project-linked software use at 4.0% of revenue in the first year, declining to 3.0% by the fifth year.	Counting it as the same line as fixed software subscriptions.
Marketing & Business Development	Variable	Model the revenue-linked line at 12.0% in the first year, falling to 8.0% by the fifth year.	Double counting the $120,000 first-year marketing budget and the 12.0% marketing line.

How does break-even shift from a lean team to a full team in environmental consulting?

Scenario table

The lean case carries the lowest revenue floor. As hiring and support costs rise, break-even moves up even though the contribution margin gets better, so the bigger team needs more sales to stay safe.

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

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 consulting team	$568k	$156k	$412k	72.5%	$0	Lowest staffing load keeps the break-even bar lower, but the cushion is still tight.
Base Year 2 consulting team	$939k	$240k	$700k	74.5%	$0	Added headcount lifts the revenue floor, so this is the key watchpoint for pipeline coverage.
Full Year 3 consulting team	$1.366m	$321k	$1.045m	76.5%	$0	Best margin mix, but the biggest team needs the most revenue before it can cover fixed cost.

What breaks the break-even plan when billable work slips or costs run hot?

Stress test

The plan breaks first if billable work slips or collections slow, because the cushion is thin. A 10% revenue drop, a 10% fixed-cost jump, or a 5-point margin hit each pushes break-even higher fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in revenue, costs, or margins.	$568,000	$0 cushion	Break-even is met, but room is tight.
Revenue shortfall	Monthly revenue slips 10% to $511,000.	$568,000	$41,000 gap	Delayed project starts can push cash below plan.
Fixed-cost increase	Fixed costs rise 10% to about $453,200 a month.	$625,000	$57,000 gap	Hiring and overhead can outrun billable work.
Margin pressure	Variable expenses rise 5 points, cutting margin to 67.5%.	$610,000	$42,000 gap	Heavier subcontracted assessments and travel eat margin.
Combined pressure	Revenue slips 10% to $511,000 while fixed costs rise 10% and margin falls 5 points.	$619,000	$108,000 gap	Slow starts, weaker collections, and early hiring strain cash.

What should the founder verify before signing the lease and hiring for this environmental consulting business?

Founder checklist

Do not lock in the lease, hires, or equipment until you have signed or nearly signed work at the Year 1 rates, enough cash for the $16.2k monthly fixed load, and $353k on hand through Month 7. If those three do not line up, break-even slips.

1Demand Proof$175-$225/hr

Verify signed or nearly signed work across Compliance Audits, ESG Advisory, Sustainability Planning, and Regulatory Monitoring at Year 1 rates before you commit to fixed costs.

2Fixed Load$16.2k/mo

Check that rent, insurance, software, supplies, telecom, accounting, training, and utilities stay near the listed monthly load before payroll, because every extra dollar pushes breakeven out.

3Margin Mix72.5% CM

Confirm Year 1 contribution margin stays near 72.5% after 8.0% technical assessment costs, 4.0% software licensing, 12.0% marketing, and 3.5% legal and regulatory consultation.

4Staff RampMonth 13-25

Make sure delivery volume fits the core team until Month 13 hires begin, then add the Junior Environmental Consultant and Marketing Specialist in Month 25 without service delays.

5Cash Cushion$353k

Hold at least the minimum cash need of $353k in Month 7, because that is the low point before the model clears payback in 22 months.

6Launch Spend$645k capex

Do not buy the office buildout, modeling platform, sensors, vehicle, and testing gear until the $645k capex plan is funded, insurance stays at $2.2k per month, and subcontractor access is lined up for field-heavy work.
