Cost classification

Break-even is only useful if each expense sits in the right bucket. Treat per-unit parts and revenue fees as variable, keep stable monthly overhead fixed, and keep launch capex out of contribution margin.

Expense	Cost	Break-Even Treatment	Common Mistake
LCD Panel Component	Variable	Include as per-unit cost of goods sold; Year 1 unit cost ranges from $45 on compact displays to $250 on window signs.	Averaging all screen sizes into one parts cost.
Controller Board	Variable	Include in contribution margin by unit; Year 1 unit cost ranges from $12 to $60 depending on model.	Treating electronics as overhead instead of unit-level cost.
Shipping and Freight	Variable	Apply as a revenue-based selling cost; modeled at 6.0% of first-year revenue and declining to 5.2% by Year 5.	Using a flat monthly freight amount despite unit growth.
Payment Processing Fees	Variable	Apply to sales revenue; modeled at 2.9% in the first year and 2.5% by Year 5.	Leaving card fees below gross margin.
Hardware Warranty Reserve	Variable	Reserve 0.7% of revenue before calculating contribution margin, since warranty exposure rises with sales.	Booking warranty only when claims arrive.
Warehouse Lease	Fixed	Include $6,500 per month in fixed overhead for Month 1 through Month 60.	Spreading rent across units and calling it variable.
Utilities and Internet	Semi-variable	Model the $1,100 monthly base as fixed, then review usage if warehouse volume drives higher power or connectivity needs.	Assuming utilities stay flat at higher shipment volume.
Added Warehouse, Support, and Sales FTE	Semi-fixed	Add payroll in steps as volume grows; first-year salaried payroll is $305,000 before later FTE additions.	Scaling headcount smoothly with each extra unit sold.

How does break-even shift from the lean Year 1 launch case to the Year 3 base case and the Year 5 full-scale case?

Scenario table

As revenue scale rises, fixed payroll and warehouse costs rise too, but contribution still stays above them. That keeps break-even covered in every case, with more cushion in the base and full scenarios.

Planning estimates only; actual break-even will move with product mix, freight, and hiring timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 launch case	$351k	$131k	$39k	62.8%	$182k	Break-even is covered in Month 1, but the cushion is still tight.
Base Year 3 scale case	$756k	$279k	$60k	63.1%	$418k	Month 1 break-even holds, and the larger volume adds room to absorb cost swings.
Full Year 5 scale case	$1,256k	$460k	$86k	63.4%	$710k	Break-even stays covered even with the bigger payroll base.

What could push this digital display panel business off break-even?

Stress test

Year 1 revenue is roughly $351K a month against about $60K break-even revenue, so the plan has room. The real stress points are margin drift from discounting, freight, warranty claims, and slow inventory turns, and Month 1 cash is still the tight spot.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Base Year 1 revenue stays about $351K per month.	$60K	$291K cushion	Healthy cushion, but mix and freight still matter.
Revenue shortfall	Revenue falls 20% to about $281K per month.	$60K	$221K cushion	Demand softens, but break-even still clears.
Fixed-cost pressure	Fixed costs rise by $10K a month.	$76K	$275K cushion	Extra overhead is absorbable if sales hold.
Margin pressure	Contribution margin falls 5 points to 58.9%.	$65K	$286K cushion	Discounting, freight, and warranty claims lift break-even fast.
Combined pressure	Revenue falls 20%, margin drops to 58.9%, and fixed costs rise $10K.	$82K	$199K cushion	The business still clears break-even, but cash timing tightens.

What should you verify before you commit to inventory and warehouse overhead for digital display panels?

Founder checklist

Test signed demand, unit margin, supplier terms, and Month 1 cash before you buy inventory or lock the lease. In this model, break-even only works if early orders, freight, and payroll stay inside the Year 1 cost base.

1Demand Proof60 screens/mo

Confirm signed or qualified demand near 60 blended screens a month before you commit to full overhead, or the fixed base will outrun sales.

2Fixed Load$13.1K/mo

Know the monthly fixed bill before launch: warehouse lease, platform, insurance, IT and CRM, utilities, and accounting total $13.1K, so every slow month matters.

3Unit Spread$376-$1,765

Check each model's sale price against component cost from $74 to $435, plus 2.0% revenue-based COGS, so the spread still covers overhead.

4Freight Load6.7% of rev

Test shipping at 6.0% of revenue and warranty reserve at 0.7%, because that 6.7% load comes straight out of contribution.

5Supplier TermsMOQs / QC

Verify lead times, minimum order quantities, inspection steps, customs compliance, and damage policy before you place volume orders.

6Staffing Ramp$305K->$875K

Stage hiring as payroll rises from $305K in Year 1 to $875K in Year 5, and protect Month 1 cash at the $1.15M trough; showroom units, racking, the website build, and the test lab do not prove demand.
