Cost classification

Break-even is modeled in Month 7, so classification matters. If fuel, crew, or payment fees get treated as overhead, the model will overstate margin and make each booking look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Vehicle Insurance & Registration	Fixed	Include $800/month in fixed overhead from Month 1 through Month 60, even with no events booked.	Spreading it across only booked events and hiding slow-month cash burn.
Office/Storage Rent	Fixed	Include $1,200/month before bookings scale; the space is needed to store and stage the mobile setup.	Treating storage as optional until demand is proven.
Booking & CRM Software	Fixed	Include $150/month as a recurring operating expense for quotes, bookings, and customer records.	Leaving small subscriptions out because they feel immaterial.
Equipment Maintenance & Repairs	Semi-fixed	Model $500/month as the base repair allowance, then watch for step-ups as event volume and equipment wear rise.	Assuming repairs stay flat when usage increases.
Fuel & Event Consumables	Variable	Apply 8.0% of first-year revenue, declining to 6.0% by the mature year, as event-level delivery and consumable pressure.	Treating fuel, setup supplies, and spares as overhead instead of booking-level drag.
Payment Processing Fees	Variable	Apply 2.5% of first-year revenue, falling to 2.2% by the stabilized period, because fees move with paid bookings.	Using gross sales as margin without subtracting card fees.
Hourly Event Staff Wages	Variable	Apply 12.0% of first-year revenue, declining to 10.0% by the mature year, for crew tied to event delivery.	Putting setup crew in fixed payroll and overstating contribution per rental.
Event-Specific Marketing & Promotions	Variable	Apply 4.0% of first-year revenue, declining to 3.0% by the mature year, for booking-linked promotions.	Mixing event promos with the annual marketing budget and double-counting acquisition spend.

How does break-even change from lean bookings to weekend-heavy demand?

Scenario table

CM ratio is the share left after variable costs. At a 26.5% variable-cost rate, the model keeps 73.5% of revenue to cover the $12,783 monthly fixed base.

Planning assumptions only; actual booking mix, pricing, and event costs can move the result.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean ramp-up	$13,000	$3,445	$12,783	73.5%	-$3,228	Below break-even; fixed costs are not covered.
Base break-even mix	$17,901	$4,749	$12,783	73.5%	$371	Near break-even; a small booking lift covers fixed costs.
Weekend-heavy demand	$24,000	$6,360	$12,783	73.5%	$4,857	Adds cushion, but capacity limits are not modeled.

What breaks this portable bowling alley break-even plan?

Stress test

The plan is fragile to lost bookings, repair spikes, and small margin slip. Break-even sits near $174,000 of revenue, so a single miss can erase the cushion fast; keep a buffer above that line, not at it.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$174,000	$0 cushion	Break-even leaves no slack.
Revenue shortfall	One average booking is lost.	$174,663	$663 gap	One missed booking can wipe out the margin.
Fixed-cost pressure	A $500 repair spike hits the month.	$174,680	$680 gap	Repairs push the needed top line up fast.
Margin pressure	Variable expenses rise by 1 percentage point.	$174,174	$174 gap	Small fuel or labor creep cuts the cushion.
Combined pressure	One booking is lost and a $500 repair spike lands.	$174,987	$987 gap	Two small hits turn break-even into a cash drain.

How do you verify the portable bowling setup can clear break-even before you buy the trailer and truck?

Founder checklist

Don’t commit the $160K core setup until you can show at least 27 bookings a month at about $663 each. That pace is what keeps fixed costs from outrunning demand.

1Booking load27/mo

Here’s the quick math: standard rental is $150 x 3.5 hours, premium is $200 x 4.5 hours, and extended time is $250 x 1.0 hour, which lands near $663 per booking.

2Launch spend$178K

Verify the $75K trailer, $55K truck, $30K bowling gear, $8K sound system, $5K branding kit, $2K spares, and $3K storage setup are covered, because the model also carries about $3.2K a month in fixed overhead.

3Margin mix73.5% CM

Keep Year 1 variable costs near 26.5% total, made up of 8.0% fuel and consumables, 2.5% payment fees, 12.0% hourly event staff wages, and 4.0% event-specific promotions, so each event still pays its share of fixed costs.

4Crew rampMonth 19/25

Keep coverage to the owner/operator and lead event technician until bookings justify the Marketing & Sales Coordinator in Month 19 and the Event Host / Assistant Technician in Month 25, or labor will outrun demand.

5Cash cushion$776K

The model bottoms near $776K in Month 7, so hold enough reserve to reach that trough before you add payroll or chase growth with more marketing.

6Site accessPre-event

Collect deposits before event dates and verify venue access, power, parking, and floor clearance, because a portable setup only turns booked demand into cash when the site can actually take the lanes.
