Cost classification

Break-even is reliable only when fixed, variable, and step-up costs are separated. Here, Month 10 break-even can slip if specialist payroll, cloud access, or research data gets modeled as harmless overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use the $12,000 monthly rent as baseline overhead before gross margin.	Spreading rent across projects and hiding the monthly cash floor.
Software Licenses & Tools	Fixed	Use the $8,500 monthly license spend as recurring platform overhead.	Treating required tools as optional until client work starts.
CEO / Lead Consultant Salary	Fixed	Include the $180,000 annual salary as fixed operating payroll.	Leaving founder-level delivery time out of break-even math.
Senior Consultant Payroll	Semi-fixed	Step payroll up as headcount rises from 1.0 FTE to 5.0 FTE.	Modeling specialist labor as smooth when hiring happens in chunks.
Cloud Computing Access	Variable	Apply 12% of revenue in the first year, falling to 8% by the mature year.	Calling usage-based cloud access harmless overhead.
Third-Party Research & Data	Variable	Apply 6% of revenue in the first year, falling to 4% by the mature year.	Ignoring paid data that scales with project volume.
Sales Commissions & Bonuses	Variable	Apply 8% of revenue in the first year, falling to 6% by the mature year.	Counting bookings without the payout needed to win them.
Travel & Conference Expenses	Semi-variable	Start with the $4,000 monthly plan, then flex for client and event load.	Keeping travel flat while enterprise sales activity expands.

How does break-even move from a lean launch team to a full quantum consulting bench?

Scenario table

As headcount and marketing spend rise, fixed costs climb fast, so break-even revenue rises with them. The lean case is closest to the line; the base and full cases need more monthly sales, but they also create more profit once booked.

Planning assumptions only, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Year 1 lean launch team	$104K	$31K	$105K	70%	-$32K	Below break-even; losses continue until more revenue lands.
Year 2 expanded team	$263K	$72K	$149K	72.5%	$42K	Above break-even; EBITDA is positive with a modest cushion.
Year 5 full expert bench	$1.20M	$240K	$288K	80%	$673K	Far above break-even; the main risk is keeping utilization high.

What breaks the break-even plan for a quantum computing consulting firm?

Stress test

At about $150K in monthly revenue, the plan only works if enterprise sales land on time and delivery stays light on subcontractors. A 10% miss, a $10K fixed-cost bump, or a margin slip to 66% removes the cushion fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$150K	$0 cushion	Base case has no room for delay.
Shortfall	Monthly revenue runs 10% below plan.	$150K	$15K gap	Slow sales or weak retainer conversion open a monthly hole.
Fixed cost	Fixed overhead rises by $10K per month.	$164K	$14K gap	Travel, software, or rent creep pushes break-even up fast.
Margin slip	Contribution margin falls from 70% to 66%.	$159K	$9K gap	More cloud access and subcontractor-heavy work leave less to cover fixed cost.
Combined	Revenue is 10% below plan, fixed overhead adds $10K, and margin slips to 66%.	$174K	$39K gap	Sales delay plus cost creep can blow through the cushion.

What should you verify before you commit to the first big spend on quantum computing consulting?

Founder checklist

Do not add payroll or big tools until you have late-stage pipeline near the $150K monthly break-even target and pricing that holds at $350 to $400 an hour. Year 1 EBITDA is -$389K, and cash bottoms at -$34K in Month 14, so runway comes first.

1Pipeline Cover$150K/mo

Verify signed or late-stage work can cover the monthly break-even target before you add payroll or fixed spend.

2Rate Check$350-$400/hr

Confirm buyers will accept these advisory, readiness, use-case, and report rates, or the revenue plan will miss break-even.

3Fixed Load$95K/mo

Keep rent, software, services, travel, and Year 1 base payroll inside this load before you commit to more overhead.

4Team Ramp5.5 FTE

Keep staffing at the Year 1 core level until billable work supports more headcount, and lock down confidentiality, data access, and client security workflows.

5Cash FloorMonth 14

Plan for the cash trough at -$34K and the Year 1 EBITDA loss so you do not run out of runway mid-build.

Test paid lead generation at this CAC first, and delay extra tools, travel, and office upgrades until utilization supports them.
