Which expenses are fixed, variable, or step up as sales grow?

Cost classification

Break-even is reliable only if $55K/month in first-year payroll and $29.5K/month in overhead sit in fixed coverage, while unit COGS, commissions, and cloud usage reduce contribution margin.

Expense	Cost	Break-Even Treatment	Common Mistake
First-year base payroll	Fixed	Count $660K/year, or $55K/month, as fixed coverage before profit appears.	Treating salaried roles as if they flex with each unit sold.
Rent, facility lease, utilities, licenses, insurance, depreciation, services, and marketing retainer	Fixed	Use $29.5K/month as overhead that contribution margin must cover.	Mis-keying $29.5K as $295K/month and overstating break-even volume.
Unit COGS by product class	Variable	Subtract $40, $100, $55, $220, and $700 per unit before fixed coverage.	Using one blended unit cost before the sales mix is stable.
Indirect manufacturing burden	Variable	Reduce contribution margin for labor, consumables, QA, power, and supplies tied to revenue.	Treating QA, power, and supplies as fixed when production rises.
Sales compensation	Semi-variable	Put sales manager salary in fixed coverage and Year 1 commissions at 3.0% against contribution margin.	Loading all sales spend into fixed overhead.
Cloud software and hosting	Semi-variable	Put $1,000/month fixed licenses in coverage and Year 1 hosting at 2.0% against contribution margin.	Treating cloud usage as fixed even as active deployments grow.
Customer support capacity	Semi-fixed	Add support payroll in steps as capacity expands from 0 FTE in Year 1 to 3 FTE by Year 5.	Assuming support grows smoothly with every sale instead of in staffing steps.

How does break-even move from lean to base to full deployment?

Scenario table

As volume steps up, revenue rises faster than fixed spend, so the cushion widens. The model still shows break-even in Month 1, but signed deployments, plant capacity, and support load decide how stable that result is.

Planning cases only: these figures are assumptions for decision-making, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean deployment	$2,333K	$396K	$845K	83.0%	$1,092K	Month 1 break-even, but the cushion is thin.
Base deployment	$5,648K	$947K	$949K	83.2%	$3,752K	Month 1 break-even with a stronger cushion, but throughput still matters.
Full deployment	$11,150K	$1,819K	$1,124K	83.7%	$8,207K	Month 1 break-even holds, and scale gives the widest cushion.

What breaks or pressures the break-even plan for this environmental technology business?

Stress test

Year 1 still clears break-even, but the cushion depends on contract timing and clean execution. The biggest threats are delayed starts, slower pilot conversion, component inflation, extra field labor, warranty rework, and cloud use above plan.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.018M	$1.315M cushion	Strong base-case buffer.
Revenue shortfall	Monthly revenue falls 10% to about $2.100M.	$1.018M	$1.082M cushion	Still above break-even, but the room narrows.
Fixed-cost pressure	Fixed costs rise 10% to about $930K.	$1.120M	$1.213M cushion	Overhead growth lifts the break-even bar.
Margin pressure	Variable expense rate rises by 3 percentage points.	$1.056M	$1.277M cushion	Small cost slippage pushes break-even up fast.
Combined pressure	Revenue falls 10% and fixed costs rise 10%.	$1.162M	$938K cushion	Still safe, but delays cut the margin for error.

What should the founder verify before locking in manufacturing and launch spend?

Founder checklist

Only lock the build if signed pilots can cover the $1.018M monthly break-even target, the $84.5K fixed base stays in range, and Month 2 cash can absorb the early capex. If any one slips, break-even moves out fast.

1Signed Pilots$1.018M/mo

Verify committed deployments can reach the monthly break-even target before you scale the launch.

2Fixed Base$84.5K/mo

Keep the monthly fixed load, including the office and manufacturing leases, covered before adding more marketing.

3Margin Check83% CM

Confirm supplier terms and the Year 1 product mix still leave about 83% contribution after unit costs and variable fees.

4Production Ramp2,550 units

Make sure the current team and line can handle 2,550 units in Year 1 before customer demand outruns output.

5QA GateMonth 4

Calibrate and finish field testing by Month 4 so customer installs do not start before the setup is ready.

6Cash Cushion$1.026M

Hold this cash level through Month 2, because the $645K launch capex lands early and the runway is tight.
