Cost classification

The Month 2 break-even date is reliable only if fixed overhead stays fixed and sales-linked costs stay below gross profit. Freight, commissions, and unit materials belong below revenue, not inside fixed overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Showroom and studio rent	Fixed	Include $12,000 per month in fixed overhead before calculating required contribution margin.	Spreading rent across each rack and treating it like a unit expense.
Insurance and liability	Fixed	Include $1,500 per month as recurring overhead during the relevant planning range.	Increasing insurance automatically with each sale instead of reviewing coverage thresholds.
Cloud ERP and CRM subscriptions	Fixed	Include $2,200 per month as a stable operating platform expense.	Scaling software as a percent of revenue without a usage trigger.
Payroll for salaried roles	Semi-fixed	Model staffing in steps, rising from $385,000 in the first year to $520,000 in the second year.	Treating salaried headcount as if it moves one-for-one with each unit sold.
Unit materials, fabrication labor, and packaging	Variable	Deduct direct materials, shop labor, and packaging per unit before contribution margin.	Putting unit materials into fixed overhead, which overstates margin at low volume.
Sales commissions	Variable	Apply 5.0% of revenue in the first and second years, then the lower forecast rates in later years.	Classifying commissions as payroll instead of a sales-linked expense.
Freight and logistics	Variable	Apply 4.0% of revenue in the first year, then the forecast rates as shipping efficiency improves.	Putting freight into fixed overhead and hiding the true cost of each shipment.
Utilities and facilities	Semi-variable	Use the planned $1,100 monthly base, then add usage-driven amounts if production or showroom activity exceeds plan.	Treating all utilities as fixed even when usage rises with operating scale.

How does break-even change from a lean Year 1 run rate to a full Year 5 run rate for sunglass display racks?

Scenario table

Break-even is covered in all three cases, but the cushion grows as sales volume rises and fixed costs spread across more units. Here’s the quick math: revenue rises faster than variable cost, so operating profit expands.

Planning estimates only; these scenario figures are model-based assumptions, not a promise of future margin or timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 run rate	$228k	$21k	$55k	91.0%	$152k	Break-even is covered, but this has the tightest cushion.
Base Year 2 run rate	$356k	$30k	$66k	91.5%	$259k	Volume still clears break-even, with better fixed-cost spread.
Full Year 5 run rate	$921k	$64k	$104k	93.0%	$752k	Strongest cushion here; fixed costs are spread the widest.

What breaks the break-even plan for sunglass display rack sales?

Stress test

The base plan stays above break-even, but the cushion gets squeezed if retail purchase orders slip, freight runs above plan, or hiring starts before repeat orders land. A 25% revenue drop, 5-point margin hit, and 10% overhead creep still leave room.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$853k	$1.43M cushion	Base case clears break-even comfortably.
Revenue shortfall	Revenue falls 25% from the launch plan.	$853k	$856k cushion	Late retail purchase orders are the first warning.
Fixed-cost pressure	Fixed overhead rises 10%.	$938k	$1.34M cushion	Showroom and payroll creep cut room fast.
Margin pressure	Contribution margin falls 5 points to 59.7%.	$925k	$1.35M cushion	Freight quotes above plan squeeze the margin.
Combined pressure	Revenue falls 25%, margin falls 5 points, and fixed overhead rises 10%.	$1.02M	$692k cushion	Delayed orders and early hiring would bite first.

Has the founder proved enough orders, margin, and cash before locking the showroom and buildout?

Founder checklist

Don’t commit to the $12,000 monthly showroom until signed or near-signed orders can support the first-year path to 4,200 units, about 350 a month, and a $651 average order value. That’s the base case behind the Month 2 break-even target.

1Purchase Orders4,200 units

Confirm signed or near-signed orders can reach 4,200 first-year units, about 350 a month, because that is the demand proof behind the break-even plan.

2Rent Load$55.2K/mo

Verify the first-year fixed load can carry the $12,000 showroom rent, since the full overhead and salary stack runs about $55.2k per month before variable costs.

3Mix Margin65% CM

Check that the Year 1 product mix still lands near a 65% contribution margin after unit COGS, 5.0% sales commissions, and 4.0% freight.

4Unit Cost$171/unit

Test material and fabrication quotes at about $171 per unit on the Year 1 mix before you commit to inventory, because small overruns hit margin fast.

5Cash Floor$1.146M

Protect the Month 1 minimum cash need of $1.146M before spending the planned $224.5k capex, so the buildout and early orders do not squeeze working cash.

6Staff RampMonth 13 hire

Keep hiring tied to booked demand, not forecast hope, and do not bring forward the Month 13 customer success role unless orders are already clearing break-even.
