Which workshop expenses stay fixed, and which move with bookings?

Cost classification

Break-even in Month 14 only holds if direct materials, booking fees, and marketing are separated from true overhead. Misclassifying these costs can overstate margin and hide the real monthly cash load.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop Studio Rent	Fixed	Model at $3,200 per month across the planning range.	Treating rent as per-student spend.
Utilities and Internet	Semi-variable	Start with the $450 monthly base, then review usage as shop hours rise.	Assuming utilities stay flat at higher class volume.
Instrument Material Kits	Variable	Apply as 11.0% of revenue in the first year.	Burying kit spend in overhead instead of gross margin.
Workshop Consumables	Variable	Apply as 2.0% of revenue in the first year and track waste.	Ignoring small items that scale with each session.
Marketing and Lead Generation	Semi-variable	Model at 5.0% of revenue in the first year, with channel checks by booking source.	Assuming every marketing dollar converts efficiently.
Booking Platform Commissions	Variable	Apply as 2.0% of revenue because it is tied to paid bookings.	Leaving commissions out of contribution margin.
Tool Maintenance and Repair	Semi-fixed	Use $200 per month, then step it up when class volume stresses tools.	Keeping repairs flat while capacity expands.
Lead Instructor	Fixed	Include the $65,000 annual salary as recurring payroll.	Testing break-even before adding instructor payroll.

How does break-even change across lean, base, and full workshop setups?

Scenario table

Year 1 prices start at $145 for public workshops, $160 for private parties, and $225 for corporate events. Lean still runs below break-even, base gets a modest cushion, and full has the widest margin as occupancy and higher-value bookings rise.

Planning assumptions only; actual break-even will move with occupancy, ticket mix, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch workshop	$18.7k	$3.7k	$15.9k	80.0%	-$1.0k	Still below break-even; fixed wages outpace margin at this scale.
Base workshop mix	$32.2k	$6.0k	$19.1k	81.2%	$7.0k	Crosses break-even around Month 14 with a modest cushion.
Full workshop scale	$67.8k	$11.9k	$22.3k	82.4%	$33.5k	Creates a strong cushion and makes growth easier to fund.

What breaks the break-even plan for the workshop?

Stress test

The plan is most exposed to underfilled public classes, higher rent, and a 5-point margin drop. A 15% revenue slide leaves about a $24k monthly gap, while fixed costs up 10% or margins down 5 points push break-even to roughly $210k to $231k a month.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	About $197k/month	$0 cushion	The plan only works at forecast occupancy.
Revenue shortfall	Revenue falls 15% below break-even.	About $197k/month	$24k gap	Underfilled public classes create the first cash hole.
Fixed-cost pressure	Workshop rent and overhead rise 10%.	About $216k/month	$19k gap	Rent pressure pushes the break-even line higher.
Margin pressure	Variable expenses rise 5 points of revenue.	About $210k/month	$13k gap	Waste and marketing spend eat the contribution margin.
Combined pressure	Revenue falls 15%, fixed costs rise 10%, and margin slips to 75%.	About $231k/month	$48k gap	Low fill and higher overhead break the plan fast.

What should the founder verify before signing the lease and buying the tools?

Founder checklist

Don’t lock the studio or full tool set yet. The model only turns EBITDA positive in Year 2, reaches break-even in Month 14, and needs a large cash cushion, so recurring bookings have to show up before you commit.

1Demand proofMonth 14

Before buying tools or signing the lease, verify that paid classes and the booking flow can create recurring demand fast enough to reach break-even by Month 14, with waivers and insurance already in place.

2Price test$145/$160/$225

Test the public workshop, private party, and corporate event prices in real sales, because the model depends on those tiers holding.

3Lease load$4,580/mo

Do not lock the studio until steady bookings can cover the $3,200 rent and the rest of the $4,580 monthly fixed cost stack.

4Margin mix80% CM

Keep materials, consumables, marketing, and booking fees near the modeled 20% of revenue so contribution margin stays around 80% before fixed costs.

5Staff ramp18 days/mo

Plan the lead instructor around 18 billable days a month in Year 1 and hold the assistant back if occupancy stays below 45%.

6Cash cushion$853K

Keep enough cash for the modeled $853K minimum in Month 24, since the business is still loss-making in the opening year.
