Cost classification

Break-even gets shaky when sales-linked costs are treated as fixed, because contribution margin looks too high. In the first operating year, product, packaging, postage, and payment fees should reduce margin before testing the Month 12 break-even point.

Expense	Cost	Break-Even Treatment	Common Mistake
E-commerce Platform Fees ($1,500/month)	Fixed	Include the full monthly amount in fixed overhead from Month 1 through Month 60.	Spreading it across orders and overstating unit margin.
Office & Storage Rent ($2,000/month)	Fixed	Carry as monthly fixed overhead within the current storage capacity.	Ignoring rent until order volume feels high enough.
Founder/CEO Salary (about $8,333/month)	Fixed	Use $100,000 per year divided by 12 as recurring monthly overhead.	Leaving founder pay out and creating a false break-even.
Annual Marketing Budget (about $1,667/month)	Semi-fixed	Use $20,000 per year divided by 12 as planned launch spend, not a per-box expense.	Treating acquisition spend like direct fulfillment margin.
Product Sourcing & Curation (10.0% of revenue)	Variable	Deduct from revenue before contribution margin because it rises with sales volume.	Burying discounts and overstating gross margin.
Custom Packaging & Shipping Supplies (2.5% of revenue)	Variable	Model as a revenue-linked charge for each shipped box.	Treating packaging as a one-time launch buy.
Fulfillment Labor & Postage (3.0% of revenue)	Variable	Apply to each shipment before testing break-even contribution.	Treating postage as fixed and missing order-level drag.
Payment Processing Fees (2.0% of revenue)	Variable	Deduct from every subscription and add-on transaction before fixed overhead.	Ignoring payment fees, refunds, and chargebacks in margin tests.

How does break-even change across lean, base, and full operating cases?

Scenario table

Higher-priced boxes lift revenue, but the fixed-cost load rises faster. The lean case fits launch control, the base case shows hiring pressure, and the full case only works with a much larger monthly revenue base.

Planning figures only; one-time setup spend affects cash flow, not the monthly break-even test.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$5,850	$1,024	$15,950	82.5%	-$11,124	Needs about $19.3k monthly revenue; launch is well below break-even.
Base growth case	$6,194	$1,034	$23,867	83.3%	-$18,707	Needs about $28.7k monthly revenue; hiring pressure starts here.
Full scale case	$6,600	$1,056	$35,450	84.0%	-$29,906	Needs about $42.2k monthly revenue; this is scale-only territory.

What breaks the Month 12 break-even plan for this subscription box?

Stress test

The Month 12 break-even plan is tight. At 17.5% variable expense, each $1 of sales keeps $0.825 before fixed costs, so a small hit to conversion, overhead, or fulfillment pushes the gap wider fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$19,333	$5,449 gap	Year 1 still runs below break-even.
Revenue shortfall	Lead-to-paid conversion drops to 15.0%, cutting paid revenue 25%.	$19,333	$8,920 gap	Slower subscriber growth pushes break-even past Month 12.
Fixed-cost pressure	Monthly fixed costs rise by $3,000 before subscriber density improves.	$22,970	$9,086 gap	Every added overhead dollar lifts the revenue bar fast.
Margin pressure	Variable expense rises from 17.5% to 20.0% as fulfillment labor and postage creep up.	$19,943	$6,059 gap	Margin slips, so more sales are needed to cover the same base.
Combined pressure	Conversion falls to 15.0%, CAC rises above $40, and variable expense climbs to 20.0%.	$23,693	$13,280 gap	That mix can break a Month 12 plan and force more cash.

Can this subscription box clear break-even before you lock in inventory, packaging, and hiring?

Founder checklist

Yes only if the Year 1 mix holds a $58.50 weighted price, variable costs stay near 17.5%, and you can fund the $39K launch build plus $20K of Year 1 marketing. With $5.95K in monthly fixed burn, Month 12 break-even and 23-month payback are the real go/no-go gates.

1Price proof$58.50

Verify the Year 1 mix really averages this monthly price, because the 50%/35%/15% split only works if buyers stay in the intended tiers.

2Margin test82.5% CM

Here’s the quick math: 10.0% sourcing, 2.5% packaging, 3.0% fulfillment, and 2.0% processing add to 17.5%, so every revenue dollar keeps 82.5 cents before fixed costs.

3Fixed burn$5.95K/mo

Keep software, rent, and retainer costs near this base level, because it is the first monthly load you must cover before founder pay and new hires.

4Launch gate$39K / $20K / $40 CAC

Verify the launch build, payment approval, age-gated checkout, and discreet packaging fit the plan while Year 1 marketing stays near $20K and CAC stays at $40.

5Staffing rampMonth 19

Stay founder-led through the first 18 months, because the curation and marketing roles start in Month 19 and the support and operations roles start in Month 25.

6Cash gate$854K / Month 12

Use the Month 2 minimum cash of $854K as the reserve test, and do not commit if you cannot still reach Month 12 break-even and a 23-month payback.
