A marine cleaning business breaks even at about $459K in monthly revenue under the Year 1 assumptions Here’s the quick math: $344K fixed monthly costs divided by a 75% contribution margin equals $459K At a $309 average monthly customer price, that is about 149 active subscription customers before taxes, debt service, and owner draws The modeled break-even timing is Month 22, but the boat cleaning break-even point moves with pricing, route density, seasonality, and service mix

Which boat cleaning expenses are fixed, and which move with sales?
Cost classification
Break-even lands in Month 22 only if fixed overhead, semi-fixed fleet capacity, and job-level rates stay separate. Treat direct labor at 10.0% of first-year revenue, not as salaried payroll.

Break-Even Treatment
Common Mistake
Office Rent
Fixed
$1,500 monthly overhead; include before contribution margin.
Tying rent to job count.
Business Insurance
Fixed
$800 monthly overhead; keep stable in the monthly break-even base.
Treating it as per-boat.
Software Subscriptions
Fixed
$600 monthly overhead for CRM, scheduling, and accounting tools.
Burying it inside supplies.
Vehicle Lease/Depreciation
Semi-fixed
$2,000 monthly capacity charge until the fleet changes.
Calling it fuel.
Technician Direct Labor
Variable
Model at 10.0% of first-year revenue; it rises with booked work.
Mixing it with salaried payroll.
Material & Supply Costs
Variable
Model at 6.0% of first-year revenue; usage rises with bookings.
Forgetting supplies scale with jobs.
Vehicle Fuel & Maintenance
Variable
Model at 3.0% of first-year revenue; route density affects margin.
Ignoring travel time and routes.
Customer Support
Semi-variable
Model at 1.5% of first-year revenue as customer volume grows.
Treating support as fully fixed.
How does break-even shift across lean, base, and full marine cleaning scenarios?
Scenario table
Lean, base, and full change break-even because revenue per route and the service mix shift faster than fixed overhead. More premium work and denser routes lift contribution margin, while the same fixed base can still keep the lean case in the red.
Planning assumptions only; actual break-even can move with route density, labor mix, and customer retention.
What breaks the break-even plan if bookings slow or costs creep up?
Stress test
The base plan has only a small cushion, so a 15% revenue miss or a 5-point jump in variable load can push it into loss. Fixed-cost creep is the biggest drag because it lifts the break-even bar fast.

All three pressures together require a much bigger revenue base.
Is this marine cleaning launch ready to break even before you buy more vans and hire up?
Founder checklist
Validate roughly 149 active subscribers at a $309 blended monthly price before the next fleet and hiring step. If CAC drifts above the $150 Year 1 assumption or marina access stays thin, the Month 22 break-even target gets pushed out.
1Demand Proof149 customers
Validate roughly 149 active subscribers and keep CAC near the $150 Year 1 assumption so growth is real, not just expensive lead flow.
2Margin Check75% CM
The 60/30/10 mix produces a $309 average monthly price and about 75% contribution margin, so direct labor, supplies, fuel, and fees must stay on plan.
3Fleet Timing$180K capex
Stage the $180K launch package and confirm marina access before you buy the next van, or the fleet will outrun booked work.
4Fixed Load$34.4K/mo
Keep fixed monthly costs near $34.4K while bookings build, because that is the overhead the first-year model has to carry.
5Route Density4.0 hrs/customer
Use the 4.0 billable hours per active customer to prove routes stay dense enough before you add the Month 13 ops and sales hires.
6Cash Cushion$362K min cash
Protect at least the $362K cash cushion, because the model bottoms in Month 28 and payback takes 46 months.
