Which expenses are fixed, and which move with sales in a plain-language writing service?

Cost classification

Break-even is only reliable if fixed payroll and rent stay below gross profit after variable fees. In the first operating year, fixed rent and tools are $8,100/month before payroll, so don’t bury referral fees or subcontractors in overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
CEO and Principal Consultant	Fixed	Include the $145,000 annual salary from Month 1 as fixed monthly payroll.	Treating founder delivery time as free capacity.
Senior Plain Language Editor	Fixed	Model each approved full-time role as fixed payroll within the planning year.	Moving salaried editing labor with each project.
Subject Matter Writer	Fixed	Classify as fixed when salaried; first-year staffing is 2.0 FTE at $85,000 each.	Counting salaried writers as variable subcontract labor.
Subject Matter Expert Subcontractors	Variable	Deduct as a revenue-linked charge; the first-year rate is 12.0% of revenue.	Treating subcontractors as overhead instead of margin drag.
AI Text Analysis API Fees	Variable	Deduct from contribution margin; usage runs from 3.0% in the first year to 5.0% in the mature year.	Putting usage fees below break-even as fixed software.
Referral Partner Fees	Variable	Apply only to referred sales; the rate starts at 8.0% and falls to 5.5% by the mature year.	Blending referral fees into general overhead.
Office Rent	Fixed	Use $4,500/month from Month 1 through Month 60 in fixed overhead.	Spreading rent as a percentage of revenue.
Annual Marketing Budget	Semi-variable	Model the planned annual spend, then test volume using CAC from $1,200 to $900.	Calling all marketing variable without a base budget.

How does break-even shift from lean to base to full scale for this plain language writing service?

Scenario table

Break-even rises with scale because fixed staffing and overhead grow faster than the margin benefit from higher revenue. Using revenue × contribution margin minus EBITDA, implied fixed load goes from about $66k/month in lean mode to about $217k/month in full scale.

Planning cases only; actual break-even will move with sales mix, hiring timing, and delivery speed.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean founder-led delivery	$123k	$34k	$66k	72%	$22k	Near the ~$92k break-even floor.
Base scaled service mix	$366k	$94k	$131k	74.5%	$142k	Clears the ~$176k break-even floor.
Full mature service mix	$721k	$173k	$217k	76%	$331k	Wide cushion above the ~$286k break-even floor.

What breaks the break-even plan for this writing service?

Stress test

The base plan clears break-even, but the cushion can shrink fast. A 15% revenue drop, a 10% fixed-cost jump, or a 5-point margin hit still leaves profit, but the combined case turns the month red.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$91.7k	$31.3k cushion	Base Year 1 revenue clears break-even with room to absorb swings.
Revenue shortfall	Revenue falls 15% to about $105k a month.	$91.7k	$13.3k cushion	Still profitable, but operating profit falls to about $9k.
Fixed-cost pressure	Fixed load rises 10% to about $72.6k a month.	$100.9k	$22.1k cushion	Hiring or overhead growth eats into the cushion.
Margin pressure	Variable expenses rise to 33% of revenue.	$98.5k	$24.5k cushion	Subcontractor, API, and referral costs push the floor up.
Combined pressure	Revenue falls 15%, variable expenses rise 5 points, and fixed costs rise 10%.	$108.4k	$3.4k gap	That mix flips the month to about a $3k loss.

Can this plain-language writing service clear break-even before you add payroll and office spend?

Founder checklist

Don’t add payroll, rent, or tools until the pipeline can clear the $92k monthly break-even target. The model shows Month 6 breakeven and a $762k cash trough, so Year 1 rates and CAC have to hold before you scale.

1Break-even target$92k/mo

Make sure signed work can clear the $92k monthly break-even target before you add more payroll or office cost.

2Price floor$175-$300/hr

Hold Year 1 rates at $175, $150, $225, and $300 per hour so document, retainer, audit, and workshop work stays on plan.

3Contribution72% CM

Keep variable costs near 28% of revenue, which leaves about 72% contribution before fixed overhead.

4Delivery bench18.5→22.5 hrs

Build a contractor bench before active customer hours rise from 18.5 to 22.5 per month, or delivery will bottleneck.

5Cash trough$762k

Protect the Month 6 cash trough at $762k, and don’t fund the $128k launch build unless that cushion survives.

6Launch spend$45k / $1.2k CAC

Keep Year 1 marketing near $45k unless CAC falls below $1,200, because weak pipeline math will drag break-even out.
