Cost classification

Your Month 2 break-even only holds if sales-linked parts, fees, and labor steps are sorted correctly. Misclassifying upgrades, labor overruns, or shipping will overstate margin and make the unit target look too easy.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop Rent	Fixed	Use $6,500 per month across the planning range.	Lowering rent per bike before volume exists.
Marketing and Social Media	Fixed	Use $2,500 per month unless the plan adds campaigns.	Linking all marketing spend to each sale.
Titanium Tubing Set	Variable	Apply $850 for each Titanium Road Racer produced.	Treating component upgrades as free margin.
Carbon Fiber Prepreg	Variable	Apply $700 for each Carbon Gravel Explorer produced.	Using average margin while ignoring material mix.
Shipping and Logistics	Variable	Apply 3.5% of first-year revenue, then use the forecast rate.	Forgetting freight rises with shipped orders.
Sales Commissions	Variable	Apply 2.0% of revenue in each forecast year.	Counting gross sales before commission leakage.
Utilities and Power	Semi-variable	Start with the $1,200 monthly base, then test usage at higher build volume.	Assuming machine-heavy months have no power lift.
Master Frame Builder Payroll	Semi-fixed	Add $95,000 per full-time builder when capacity steps up.	Treating labor overruns as free margin.

How does break-even change from lean to base to full capacity in a custom bicycle building shop?

Scenario table

Break-even gets less fragile as monthly revenue rises, but payroll and shop overhead climb too. The real test is whether the team can add builds and fit sessions without slowing sourcing or build work.

Planning assumptions only; actual break-even will shift with mix, labor use, and sourcing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean custom shop	$104.8k	$28.2k	$38.3k	73.1%	$38.3k	Thin cushion; delays in builds or fittings can break even fast.
Base custom shop	$176.8k	$48.6k	$55.8k	72.5%	$72.3k	Best balance here; break-even holds if fit slots and sourcing stay on schedule.
Full-capacity custom shop	$266.7k	$74.4k	$75.0k	72.1%	$117.3k	More cushion, but only if build capacity and parts flow keep pace.

What breaks the break-even plan for a custom bicycle shop?

Stress test

Here’s the quick math: base revenue about $1.047m against about $383k fixed overhead and payroll gives a wide cushion. Watch fewer than 4 to 5 builds a month, delayed fit bookings, rework, and unpaid deposits.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$498k	$550k cushion	Current demand sits well above break-even.
Revenue shortfall	Revenue falls 20% while margin holds.	$498k	$340k cushion	The plan still clears break-even, but the cushion drops fast.
Fixed-cost pressure	Fixed overhead and payroll rise by $5k a month.	$563k	$484k cushion	Small cost creep moves the break-even line up fast.
Margin pressure	Gross margin slips 5 points from rework or substitutions.	$533k	$514k cushion	Rework and substitutions push break-even higher even if sales hold.
Combined pressure	Revenue falls 20% and gross margin slips 5 points.	$563k	$275k cushion	Still positive, but cash discipline has to stay tight.

What should you verify before you sign the lease or buy the shop equipment?

Founder checklist

Don’t lock the lease or major equipment until paid deposits and booked fit sessions show the first-year volume is real. The model breaks even in Month 2, but it also needs $1.148M of minimum cash, so demand has to land before the fixed-cost stack does.

1Deposit ProofPaid deposits

Verify customers are putting money down before you sign fixed commitments, because deposits prove demand better than interest.

2Build Flow105 builds

Check that appointment flow can really support 105 Year 1 builds, because one master frame builder has to carry that opening load before you add headcount.

3Fit Flow120 sessions

Confirm you can book 120 fit sessions in Year 1, since fit work is the front end of the custom sale and tells you if launch demand is real.

4Unit Margin78% CM

At the Year 1 mix, direct materials plus shipping and commissions leave about 78% contribution, so the build mix has to stay tight for break-even to hold.

5Fixed Burn$38.3K/mo

Keep the monthly burn at about $38.3K, including $800 insurance and $2,500 marketing, and only hold that spend if booked orders are keeping pace.

6Cash Floor$1.148M

Protect the Month 2 cash floor, lock terms on tubing, groupsets, wheels, paint, and fit supplies, and delay noncritical equipment if runway gets tight.
