Cost classification

Break-even only works if rent, payroll steps, materials, and freight sit in the right buckets. Misclassify one large item, and Month 1 break-even can look safer than cash operations really are.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Lease	Fixed	Use $15,000 per month as baseline overhead from Month 1 through Month 60.	Treating rent as a per-bike expense.
Salaried Staff	Semi-fixed	Model payroll in staffing steps; first-year salaries equal about $537,500 annually, or $44,792 per month.	Ignoring full-time equivalent jumps as volume rises.
Frameset	Variable	Apply by model at $55 to $150 per bike produced.	Averaging all frame costs before product mix stabilizes.
Groupset	Variable	Apply by model at $30 to $80 per bike produced.	Missing the margin impact of premium models.
Motor Battery	Variable	Apply $130 only to the electric city model units.	Applying battery expense to non-electric models.
Assembly Labor	Variable	Apply $12 to $40 per bike as direct production labor.	Double-counting it with technician salaries.
Shipping Logistics	Variable	Use 3.0% of revenue in the first year, declining to 2.0% by year five.	Treating freight as fixed monthly overhead.
Utilities	Semi-variable	Use the $2,500 monthly utility bill plus factory utilities at 0.4% of revenue.	Missing usage creep as production volume grows.

How does break-even move from a lean Year 1 mix to the base Year 3 mix and then the full Year 5 mix?

Scenario table

As the mix scales, monthly revenue rises faster than fixed overhead, so the break-even cushion widens. The main risk shifts from covering cost to keeping supply, labor, and cash aligned with demand.

Planning assumptions only; actual break-even will move with product mix, scrap, freight, labor, and factory use.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 mix	$300,000	$50,417	$66,392	83.2%	$183,191	Sales clear break-even with a solid cushion.
Base Year 3 mix	$935,833	$148,991	$85,767	84.1%	$701,075	Break-even stays well covered as volume scales.
Full Year 5 mix	$2,253,500	$339,956	$94,100	84.9%	$1,819,444	Largest cushion, but it depends on supply and cash.

What breaks first if bike sales slip or costs run hot?

Stress test

Year 1 has a wide cushion: about $218K above break-even at $300K monthly revenue. The biggest risks are mix drift below $1,440 average selling price, contribution margin under 81%, or a 20% jump in fixed costs.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$82K	$218K cushion	ASP above $1,440 keeps the plan safe.
Revenue shortfall	Monthly revenue falls 10% from plan.	$82K	$188K cushion	A 10% sales drop still leaves room, but not much.
Fixed-cost pressure	Fixed costs rise 20% from plan.	$98K	$202K cushion	A 20% overhead lift cuts the cushion.
Margin pressure	Variable expenses rise 10% from plan.	$84K	$216K cushion	Contribution margin slips below 81% and break-even moves up.
Combined pressure	Monthly revenue falls 20%, variable expenses rise 20%, and fixed costs rise 10%.	$128K	$112K cushion	Still profitable, but the buffer is much thinner.

What should a bicycle manufacturer verify before signing the lease and buying the first production line?

Founder checklist

Don’t lock the lease or full payroll until the model clears unit demand, margin, and cash. In this case, that means proving at least 57 bikes a month at about $1,440 average selling price, while holding enough cash for $385K capex and the $1.131M minimum cash path.

1Demand floor57 bikes/mo

Verify monthly demand stays above 57 bikes before you add full overhead, or the fixed cost stack will outrun sales.

2Fixed load$66.4K/mo

Confirm the lease fits the full Year 1 fixed load, because $15K rent plus payroll and overhead is the cost base you must clear.

3Margin by model81-82% CM

Test each bike line on its own, since direct parts and the 0.5% quality-control cost can look fine in blend but still miss break-even by model.

4Tech ramp2→6 FTE

Check that the assembly team can scale from 2.0 to 6.0 FTE without hiding labor inside salary overhead, so production cost stays visible per bike.

5Cash cushion$1.131M

Fund the $385K capex and the Month 1 cash trough first, because the model’s minimum cash sits at $1.131M before operations stabilize.

6Launch demand$1,440 ASP

Hold launch marketing until the channel can support a $1,440 average selling price, or you may spend on demand before the mix pays back.
