Cost classification

Break-even in Month 5 depends on separating fixed capacity from revenue-linked fees. If launch rework, QA, or support gets treated like free founder time, the model will overstate margin.

Expense	Cost	Break-Even Treatment	Common Mistake
Delivery payroll	Fixed	Use first-year staffing as monthly capacity. Annual salary math is about $490k per year, or $40.8k per month.	Treating rework, QA, and support as free founder time.
Office Rent	Fixed	Include $5,500 per month from Month 1 through Month 60.	Scaling rent with revenue instead of holding it flat.
Software Development Tools SaaS	Fixed	Include $1,200 per month as baseline delivery overhead.	Dropping tools below the line because they feel small.
Cloud Infrastructure and API Fees	Variable	Model at 8% of revenue in the first year, then lower by year as assumed.	Using a flat monthly estimate when usage rises with client work.
Third-Party Voice Engine Licensing	Variable	Model at 5% of revenue in the first year.	Forgetting license fees in the contribution margin.
Sales Commissions and Referral Fees	Variable	Model at 10% of revenue in the first year.	Classifying commissions as fixed sales overhead.
Contractor Technical Quality Audits	Variable	Model at 5% of revenue in the first year because review work follows project volume.	Leaving launch QA outside break-even math.
Annual Marketing Budget	Semi-fixed	Use $45k in the first year, then step up with the planned annual budget.	Spreading spend evenly while ignoring campaign step-ups.

How does break-even change from a lean floor to Year 1 launch and Year 5 scale in a custom voice skill studio?

Scenario table

Break-even shifts because the fixed load is heavy at the start, then the mix improves as retained work and subscriptions grow. The lean floor only covers overhead, while the Year 5 case has the widest cushion.

Planning assumptions only, not guaranteed results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean studio floor	$757k	$212k	$545k	72%	$0	At this level, the studio only covers overhead.
Year 1 launch case	$152k	$43k	$61k	72%	$48k	Month 5 break-even gives the first real profit cushion.
Year 5 scale case	$940k	$188k	$186k	80%	$565k	Recurring work lifts coverage and widens the margin.

What breaks the break-even plan for this voice-skill service?

Stress test

The base plan clears monthly break-even, but the cushion is only about $76.0k in Year 1 average revenue. If sales fall 20%, overhead rises 10%, or variable costs move from 28% to 33%, breakeven climbs fast and Month 5 can slip.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Year 1 average monthly revenue is about $151.7k with a 72% contribution margin.	$75.7k	$76.0k cushion	Healthy start, but the cushion is not huge.
Revenue shortfall	Monthly revenue falls 20% to about $121.3k.	$75.7k	$45.6k cushion	Still clears break-even, but room for delay shrinks.
Fixed-cost pressure	Monthly overhead rises 10% to about $59.9k.	$83.2k	$68.5k cushion	Higher fixed cost makes sales timing more important.
Margin pressure	Variable expenses rise from 28% to 33%, so contribution margin drops to 67%.	$81.3k	$70.4k cushion	QA overages and tool spend push break-even higher.
Combined pressure	Revenue falls 20%, overhead rises 10%, and variable expenses move to 33%.	$89.4k	$31.9k cushion	This is the case that can push Month 5 breakeven later.

Is enough signed work in place before you lock in Year 1 hiring and fixed spend?

Founder checklist

Yes only if the pipeline can clear the $757K monthly break-even check and cash stays above the Month 2 low point. Hold off on more hiring, tools, and capex until demand, delivery capacity, and QA are all proven.

1Signed Work$757K/mo

Confirm booked projects and retainers can cover the break-even revenue check before Month 5, or the Year 1 cost base will outrun cash.

2Fixed Load$9.9K/mo

Verify non-payroll overhead stays near $9.9K a month, because that spend lands before salaries and any optional build-out.

3CAC$2.5K

Keep customer acquisition near the Year 1 CAC so the $45K marketing budget does not buy growth that cannot pay back fast enough.

4Delivery Bench4.0 FTE

Use the Year 1 team only if the CEO and Lead Strategist, senior developer, designer, project manager, and sales manager can cover delivery without rework.

5Cash Floor$807K

Hold the model’s $807K minimum cash reserve, since the low point hits in Month 2 and the business does not break even until Month 5.

6Launch QAMonth 5

Set proposal templates, change orders, contractor backup, and QA gates before launch so certification rework does not slow paid delivery.
