Which expenses are fixed and which move with sales for an A-frame sidewalk sign business?

Cost classification

Break-even is only useful if fixed overhead and sales-linked costs are split cleanly. Treat rent and core salaries as monthly overhead, but ads, shipping, card fees, and unit materials must reduce contribution margin.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse Rent	Fixed	Include $4,500 per month in fixed overhead for the full planning range.	Spreading rent per unit and hiding the monthly cash burden.
E-commerce Platform Subscription	Fixed	Include $350 per month as recurring overhead before calculating break-even units.	Treating the subscription as a sales fee instead of a monthly commitment.
General Manager Payroll	Fixed	Include the $85,000 annual salary as fixed payroll, or about $7,083 per month.	Leaving management payroll out because it does not sit in product COGS.
Customer Service Rep Payroll	Semi-fixed	Model one $42,000 FTE in the first year, then step staffing up as order volume grows.	Assuming support labor rises smoothly with each order instead of in headcount steps.
Digital Marketing Ads	Variable	Reduce contribution margin by 10.0% of revenue in the first year, falling to 8.0% by the mature year.	Counting gross sales as margin before paid acquisition is deducted.
Shipping and Logistics	Variable	Reduce contribution margin by 6.0% of revenue in the first year, improving to 5.0% by the mature year.	Using product margin before freight, which overstates break-even profit.
Payment Processing Fees	Variable	Deduct 2.9% of first-year revenue as a sales-linked fee in the break-even formula.	Ignoring card fees because each transaction looks small.
Product Materials by Unit	Variable	Deduct unit materials and direct labor from each sale, such as $38.50 for a Classic Wood A-Frame.	Confusing inventory purchases with profit expense; inventory can use cash before it hits profit.

How does break-even change from a lean launch to the Year 1 base case and the Year 5 scale-up?

Scenario table

Break-even moves with mix and overhead. The lean test trims fixed costs but also trims demand, while the Year 5 case spreads payroll and rent across a much bigger revenue base, so cushion improves fast.

Planning assumptions only. Actual break-even will move with product mix, pricing, rent, labor, and freight.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean wood-only test	$18,500	$4,405	$20,233	76.2%	-$6,138	Good for demand testing, but this setup still misses break-even at current sales.
Base Year 1 warehouse launch	$65,833	$29,533	$27,442	55.1%	$8,859	Year 1 is slightly above break-even, so small volume dips can erase the cushion.
Full Year 5 scaled mix	$273,833	$109,563	$45,917	60.0%	$118,354	Higher volume spreads overhead well, so break-even risk drops and profit room opens up.

What breaks the break-even plan for A-frame sidewalk sign sales?

Stress test

At the base plan, revenue is about $658k and break-even sits near $497k, so the cushion is about $161k. That buffer gets thin fast if ads, freight, or payroll move before volume does.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base plan.	$497k	$161k cushion	Solid buffer, but not wide.
Revenue shortfall	Monthly revenue comes in 15% below plan.	$497k	$62k cushion	A sales miss cuts the buffer by more than half.
Fixed-cost increase	Fixed overhead rises by $89k a month.	$658k	$0 cushion	EBITDA hits zero at the planned run rate.
Margin pressure	Contribution margin falls to 41.7% from higher ads, freight, and fees.	$658k	$0 cushion	A small cost slip wipes out the cushion.
Combined pressure	Revenue falls 10% and margin stays at 41.7%.	$658k	$66k gap	Two small misses push the model below break-even.

Can you prove the A-frame sign model holds margin before you buy inventory, lease the warehouse, and hire ahead of orders?

Founder checklist

Don’t lock in the warehouse, equipment, or hires until supplier quotes, freight, and paid demand all support the model. If margin slips or Month 2 cash drops under the $1.129M floor, pause the spend and fix the mix first.

1Landed margin71%-80% GM

Test the $185, $240, $210, $160, and $45 price points against supplier quotes for wood, steel, PVC, vinyl, ink, hinges, packaging, and labor, so each SKU still clears gross margin before freight and ads.

2Fixed burn$27.4K/mo

Confirm the $4,500 warehouse rent and about $20.8K of Year 1 payroll stay inside a $27.4K monthly burn, because fixed costs are the first hurdle before any variable margin lands.

3Fee stack8.9%

Quote outbound freight against the 6.0% shipping assumption and card fees against 2.9%, because those two lines already take 8.9% of sales before you spend on ads.

4Paid demand$790K

Do not fund the full 10.0% ad load until paid orders show up at the assumed mix, since Year 1 revenue is modeled at $790K and Year 2 at $1.235M.

5Capacity ramp5.6K→23.7K

Make sure one production supervisor and the planned fulfillment team can move from 5,600 units in Year 1 to 23,700 in Year 5, and only add customer service and fulfillment headcount when repeat orders justify it.

6Cash floor$1.129M

Keep the opening-month cash buffer above the Month 2 trough and stage the $110.5K capex across the first months, because the model’s minimum cash need is $1.129M and payback takes 26 months.
