Cost classification

Break-even is only useful when fixed shop costs stay separate from per-crate inputs. If lumber, build labor, delivery fees, or commissions get treated as overhead, the model overstates margin and makes Month 2 break-even look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop Lease	Fixed	Use $12,000 per month in the fixed operating base.	Spreading rent across crates and hiding unused shop capacity.
Workshop Utilities	Semi-variable	Start with the $1,800 monthly base, then watch usage as machinery hours rise.	Treating all power use as fixed when production shifts run longer.
Liability and Art Insurance	Fixed	Include $2,500 per month as fixed coverage within the planning range.	Leaving insurance out because it does not touch each crate.
Marketing and Trade Shows	Semi-fixed	Model $3,000 per month, then step it up only when the sales plan expands.	Making it fully variable even though spend happens before orders close.
Vehicle Maintenance	Semi-variable	Use the $1,200 monthly base, with extra wear tied to delivery volume.	Calling delivery support overhead and missing volume-driven vehicle strain.
Lumber, foam, hardware, adhesives, and direct labor	Variable	Charge these inputs to each crate based on the product build.	Treating skilled build labor and rework as overhead instead of job-level inputs.
Shipping and Logistics Fees	Variable	Apply the revenue-linked fee, shown as 4.0% in the first year.	Leaving freight below gross margin and overstating contribution per crate.
Sales Commissions	Variable	Apply commissions as 3.0% of sales tied to closed orders.	Budgeting commissions as a flat salary line instead of sales-driven spend.

How does break-even change across lean, base, and full production for custom art shipping crates?

Scenario table

Break-even shifts fast when volume and crate mix change. The lean case still runs below the line because fixed overhead is too heavy, while the base and full cases clear it with a much wider cushion.

Planning figures only; actual results will move with product mix, labor pace, waste, and shipping.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean art-crate mix	$694k	$292k	$549k	57.9%	-$147k	Still below break-even; fixed costs outrun contribution.
Base custom-crate mix	$2,354k	$991k	$549k	57.9%	$815k	Clears break-even and leaves a solid operating cushion.
Full run-rate mix	$7,030k	$2,735k	$890k	61.1%	$3,405k	Strong cushion, but only if the higher-value mix holds.

What breaks the break-even plan for custom art shipping crates?

Stress test

The base plan has about $815k of operating cushion, so it can absorb some noise. The weak spots are fewer custom orders, higher lumber and foam prices, overtime, rework, and rent or payroll creep.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base plan.	$947k	$815k cushion	The plan stays above break-even with room to absorb shocks.
Revenue shortfall	Revenue falls 20% to $1,883k while variable costs scale with volume.	$1,341k	$542k cushion	Fewer custom orders cut the buffer fast.
Fixed-cost increase	Workshop lease, payroll, and overhead rise 10%.	$1,594k	$760k cushion	Rent and payroll creep narrow the cushion.
Margin pressure	Lumber, foam, and overtime push variable costs up 10%.	$1,638k	$716k cushion	Material inflation and rework hit margin first.
Combined pressure	Revenue falls 20% and fixed and variable costs each rise 10%.	$1,144k	$197k gap	At the $947k break-even point, it flips to a $197k gap.

What should a founder verify before signing the lease for custom art shipping crates?

Founder checklist

Do not sign the lease or buy the core equipment until you’ve proven orders, can carry the $54.9K monthly fixed load, and have cash for the Month 2 trough. The model hits breakeven fast, but only if the first pipeline and launch timing are real.

1Pipeline Proof$2.8M Y1

Confirm committed orders or a live quote pipeline before you sign the $12,000 monthly workshop lease, because Year 1 revenue only works if demand starts early.

2Fixed Load$54.9K/mo

Verify the monthly burn from the lease, utilities, insurance, marketing, software, vehicle, and wages for one general manager, one design engineer, two master carpenters, and one sales rep.

3Margin Mix61.9% CM

Contribution margin (CM) is what’s left after variable costs, and the Year 1 mix still clears about 61.9% after materials, shipping, and sales commissions.

4Staffing QC5 FTEs

Plan around one general manager, one design engineer, two master carpenters, and one sales rep, and set checks for foam fit, seals, hardware, labeling, and final inspection so rework does not eat margin.

5Shop Flow238/mo

Map saws, assembly benches, dust extraction, racking, and delivery flow so the team can hit 238 crates a month in Year 1 without bottlenecks.

6Launch Capex$230K

Time the $65K CNC router, $25K saws and jointers, $15K dust extraction, $85K truck, and $40K workshop infrastructure, and test supplier lead times on kiln dried lumber, archival foam, premium plywood, hardware, insulated panels, sensors, and HVAC components before stocking climate controlled units.
