Cost classification

Break-even gets reliable only when payroll, overhead, tools, and acquisition spend behave correctly in the model. Here, Month 28 break-even depends on separating stable monthly overhead from client-driven usage and step-up hiring.

Expense	Cost	Break-Even Treatment	Common Mistake
Salaried CEO, engineers, support, and sales team	Semi-fixed	Model as capacity blocks: Year 1 payroll is $35k/month, rising to about $69.6k/month in Year 3 as full-time headcount expands.	Treating every new client as requiring a new hire.
Office rent, utilities, insurance, legal, internal software, travel, and supplies	Fixed	Use $6.2k/month as recurring overhead across the planning range from Month 1 through Month 60.	Burying overhead inside gross margin.
Core software licensing, cloud backup storage, and security tools	Variable	Apply as revenue-linked delivery expense: 11.0% of revenue in Year 1, improving to 8.7% in Year 3.	Ignoring per-client tool creep as accounts scale.
Sales commissions, referral fees, digital marketing, and certifications	Variable	Apply as growth-linked expense: 14.0% of revenue in Year 1 and 12.3% in Year 3, separate from fixed overhead.	Calling customer acquisition spend fixed when it scales with growth.
Client onboarding and monthly support hours	Semi-variable	Base staffing covers normal volume, but workload moves with active clients: 20 hours/month per customer in Year 1 and 17 in Year 3.	Pricing every account as low-touch.

How does break-even shift from a lean launch to a full-service model?

Scenario table

More service depth raises revenue per client and lifts margin, but it also pulls payroll and tools forward. So the break-even line climbs from lean to full-service, and the base case is the cleanest operating target.

Planning case only: these break-even figures are modeled assumptions, not a guarantee demand lands on schedule.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean remote-first launch	$55k	$13.8k	$41.3k	75%	$0	Lowest support load, but the cushion is thin if sales slip.
Base Month 28 operating plan	$96k	$20.2k	$75.8k	79%	$0	Matches the modeled break-even month, so timing risk still matters.
Full-service expansion	$135k	$23k	$112.1k	83%	$0	Best pricing power, but payroll growth demands steadier demand.

What breaks the break-even plan for this IT infrastructure business?

Stress test

The base plan is basically at breakeven. A 10% revenue drop or a 10% fixed-cost jump opens a roughly $75k gap, and a move to 26% variable expenses pushes break-even above $1.02m.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$959k	$0 cushion	The model is only barely covered.
Revenue shortfall	Revenue falls 10% to $864k.	$959k	$75k gap	A small churn wave wipes out the cushion.
Fixed-cost increase	Fixed costs rise 10% to $834k.	$1.06m	$76k gap	Overhead growth needs more booked revenue to hold even.
Margin pressure	Variable expenses rise to 26%, cutting contribution margin to 74%.	$1.02m	$48k gap	Higher labor, licensing, or subcontractor spend weakens each dollar earned.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and variable expenses rise to 26%.	$1.13m	$195k gap	Churn, overtime, and tool overruns can blow a small cushion wide open.

What should you verify before you commit to the first engineers and tool contracts?

Founder checklist

Before you lock in the first hiring wave and tool stack, make sure signed recurring revenue, CAC, and support load still fit the model. This plan only works if the business can reach $55K a month in Year 1, then $96K by Month 28, without draining cash too early.

1Revenue proof$55K / $96K

Check signed recurring revenue against $55K in Year 1 and $96K by Month 28, because the break-even line only works if new accounts close fast enough.

2CAC control$2.5K

Keep customer acquisition cost near $2,500 in Year 1, or marketing spend will outrun the first wave of accounts before the service base is stable.

3Fixed load$41.2K/mo

Confirm payroll plus overhead stay close to $41.2K a month before variable costs, so added headcount does not push break-even past what bookings can carry.

4Margin check75% CM

Make sure service contribution margin stays near 75% after 11% COGS and 14% variable spend, or the break-even target moves up fast.

5Support load20→17 hrs

Test that each active customer stays around 20 labor hours a month in Year 1 and 17 by Year 3, so service demand does not outrun the team.

6Runway reserve$217K / $113K

Hold the projected $217K minimum cash for Month 28 and keep the $113K launch capex separate from monthly overhead, or setup spend will eat the runway before breakeven.
