Cost classification

Break-even in Month 6 only holds if direct fieldwork and sales-linked spend reduce contribution margin, not overhead. Misclassifying lab work, surveys, or travel can make the model look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Lease	Fixed	Include the $8,000 monthly lease in fixed overhead for the full planning range.	Spreading rent across projects and hiding the true monthly hurdle.
Utilities & Internet	Fixed	Treat the $1,200 monthly charge as fixed operating overhead.	Linking basic office service bills to project revenue without usage data.
Laboratory Testing & Field Equipment Rental	Variable	Deduct from revenue as direct delivery spend, starting at 8.0% in the first year.	Treating lab work and rented field gear as overhead instead of margin drag.
Specialized Data Acquisition & AI Platform Usage	Semi-variable	Model usage-linked data spend separately from the fixed cloud platform base; usage starts at 6.0% of revenue.	Putting all platform spend in fixed overhead and overstating contribution margin.
Project Travel & Accommodation	Variable	Deduct travel from project revenue, starting at 5.0% in the first year and falling with scale.	Calling site travel overhead when it rises with field assignments.
Sales & Business Development Commissions	Variable	Treat commissions as revenue-linked selling expense, starting at 7.0% in the first year.	Budgeting commissions as a flat sales salary and missing margin pressure.
Project Manager Payroll	Semi-fixed	Add payroll in capacity steps, with hiring beginning in Year 2 at 1.0 full-time equivalent.	Smoothing headcount monthly instead of showing the step-up in overhead.
Junior Environmental Analyst Payroll	Semi-fixed	Model analyst staffing as stepped capacity, beginning in Year 2 and rising to 2.5 full-time equivalents by Year 5.	Treating delivery staff as fully variable when salaries commit before revenue lands.

How does break-even shift across lean, base, and staffed Environmental Impact Assessment formats?

Scenario table

Lean stays right on the break-even line because 74% contribution barely covers $615K of fixed costs. Base and staffed cases add cushion, but they only work if demand supports the bigger team and overhead.

These are planning assumptions, not guarantees; actual results will move with scope, staffing, and project mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pre-hire case	$831K	$216K	$615K	74%	$0K	Break-even risk is tight; the floor only covers overhead.
Base launch case	$1,218K	$317K	$615K	74%	$286K	Healthy cushion; this is the launch planning case.
Staffed growth case	$2,777K	$666K	$898K	76%	$1,213K	Strong cushion, but only after pipeline can support added staff.

What breaks the break-even plan if projects slip or costs rise?

Stress test

What this estimate hides is timing: a 10% revenue miss, a 10% fixed-cost creep, or variable expenses rising from 26% to 30% can shrink the cushion fast. Base Year 1 monthly revenue is $1,218,000 versus $831,000 break-even, so the starting cushion is $387,000.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$831,000	$387,000 cushion	Healthy start, but the cushion still depends on Month 6 break-even.
Revenue shortfall	Revenue falls 10% in the first year.	$831,000	$265,200 cushion	A 10% miss still clears break-even, but it burns $90,000 of contribution.
Fixed-cost increase	Fixed overhead rises 10% before revenue scales.	$914,100	$303,900 cushion	Overhead creep trims the buffer and raises the monthly sales hurdle.
Margin pressure	Variable expenses rise from 26% to 30%.	$878,486	$339,514 cushion	Higher field spend narrows contribution and pushes break-even up.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and variable expenses rise to 30%.	$966,334	$129,866 cushion	Stacked pressure cuts the cushion hard and can delay Month 6 break-even.

Is your environmental impact assessment practice ready for the fixed-cost step-up?

Founder checklist

Before you add headcount and fixed spend, confirm the work is already close to hand. The model only holds if you have signed or late-stage work near $831K monthly revenue, can absorb the $640K cash low in Month 7, and can scale without hiring ahead of use.

1Pipeline$831K/mo

Verify signed or late-stage work is near this level before you expand fixed overhead.

2Fixed load$16.5K/mo

Check that office, software, insurance, legal, and admin costs stay near this monthly base before the team grows.

3Margin74% CM

Confirm Year 1 pricing still leaves room after laboratory testing, data tools, travel, and sales commissions.

4Capacity5 projects/mo

Validate the current team can handle about five full-project equivalents each month before you pull Year 2 hires forward.

5Cash$640K

Hold enough cash to pass the Month 7 low point, since capex and payroll can outrun collections early.

6Workflow$330K capex

Stage the planned buildout only after report drafting, field surveys, lab review, and client billing are mapped end to end.
