Cost classification

Break-even works only if fixed overhead stays above the line and sales-linked costs reduce margin. Here, Month 26 break-even depends on treating royalties, fulfillment, and unit production as variable, not office overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $3,500 per month in fixed overhead for the active planning range.	Spreading rent across units and understating the monthly break-even floor.
Software Subscriptions	Fixed	Use $800 per month as recurring operating overhead from Month 1.	Treating subscriptions as a per-book charge when they do not move with sales volume.
Printing Cost	Variable	Charge each printed unit: $1.50 hardcover, $0.80 paperback, and $1.20 picture book.	Treating print invoices as fixed because orders may be placed in batches.
Author Royalties & Advances	Variable	Reduce contribution margin by the modeled revenue rate, starting at 8.0% in the first year and reaching 10.0% by Year 5.	Treating royalties as fixed and overstating profit on higher sales.
Distribution & Warehousing Fees	Variable	Reduce margin by the modeled revenue rate, from 8.0% in the first year to 6.0% by Year 5.	Booking fulfillment-related charges as office expense instead of sales-linked expense.
Ebook Platform Fee	Variable	Apply the 1.0% fee against ebook revenue before calculating ebook contribution.	Using print margin assumptions for ebooks and missing platform fees.
Payroll Hiring Gates	Semi-fixed	Add payroll in steps as roles start: Production Coordinator in Month 7, Sales & Rights Manager in Month 13, and Junior Editor in Month 25.	Smoothing headcount too early and hiding the margin needed after each hire.
Title Campaign Spend	Semi-variable	Model by launch activity or catalog scale, not as a flat payroll-like monthly expense.	Treating ad spend as permanent payroll instead of scaling it with releases.

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

Scenario table

Lean tests demand with a small catalog, base reaches Month 26 break-even with a thin cushion, and full adds enough revenue to cover the larger team. The break-even line moves with format mix and fixed payroll.

Planning assumptions only; actual break-even will move as mix, volume, and overhead change.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean publishing mix	$305k	$68k	$317k	77.6%	-$11k	Needs about $409k/month to break even.
Base publishing mix	$535k	$119k	$403k	77.8%	-$5k	Month 26 is the break-even point, but the cushion stays thin.
Full catalog scale	$809k	$179k	$443k	77.9%	$10k	Runs above break-even and starts to build real cushion.

What breaks the break-even plan in book publishing?

Stress test

The base plan has only a small cushion: about $535k in monthly revenue versus roughly $518k at break-even. That leaves little room for slow title sell-through, higher freight, richer royalties, or marketing spend before channel proof.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$518,000	$17,000 cushion	Small cushion, so title velocity has to hold.
Revenue shortfall	Sales fall 10% to about $481k per month.	$518,000	$28,000 gap	Weaker sell-through pushes the plan back into loss.
Fixed-cost pressure	Overhead rises 10% to about $443k per month.	$569,000	$34,000 gap	Early hiring or spend creep eats the cushion fast.
Margin pressure	Contribution margin drops 5 points to 72.8%.	$553,000	$18,000 gap	Richer royalties or higher freight move break-even up.
Combined pressure	Sales fall 10%, overhead rises 10%, and margin drops 5 points.	$609,000	$128,000 gap	At $481k revenue, the month is about $92k in the red.

Will the book pipeline and pricing hold before you lock in inventory, hires, and launch spend?

Founder checklist

Before you lock in inventory, payroll, and launch spend, confirm the title pipeline, format pricing, and cash cushion still support Month 26 break-even. If Year 1 units slip below 22,000 or the launch build grows past plan, delay hires and capex.

1Demand proof22K / 38.5K units

Confirm the manuscript pipeline can reach 22,000 units in the first operating year and 38,500 in the second, or the release slate is too thin.

2Launch pricing$28 / $16 / $9.99 / $24.99 / $18

Verify readers and channel buyers will accept the Year 1 price card before you spend on print, audio, and design.

3Unit margin74%-88% CM

Check that each format still clears its direct costs, royalties, distribution, and payment fees, because that margin funds the fixed burn.

4Fixed burn$31.7K/mo

Keep rent, software, legal, hosting, and Year 1 wages near $31.7K a month so breakeven math stays believable.

5Hiring rampMonth 7-25

Hold the production, rights, and junior editor hires to the Month 7, 13, and 25 ramp unless unit demand beats plan.

6Cash cushion$864K / $80K

Carry the $864K minimum cash cushion and the $80K launch build, since Year 1 EBITDA is -$128K and Year 2 is -$61K.
