Cost classification

Break-even gets unreliable when job-level expenses, monthly overhead, and hiring steps are blended together. Keep each expense in the right bucket so Month 15 break-even is tied to real operating behavior.

Expense	Cost	Break-Even Treatment	Common Mistake
Office and Storage Rent	Fixed	Use $1,500 per month through the planning range.	Spreading rent across jobs and making break-even look easier at low volume.
Business and Fleet Insurance	Fixed	Use $800 per month before calculating contribution margin.	Treating insurance as a per-service charge instead of monthly overhead.
Vehicle Lease/Loan Payments	Fixed	Use $2,500 per month while the fleet supports current capacity.	Hiding vehicle payments inside startup spending and understating operating break-even.
Cleaning Supplies & Products	Variable	Apply 8.0% of revenue in the first year, falling to 6.0% by the mature year.	Using one flat monthly supply bill even when job count changes.
Fuel & Vehicle Maintenance	Variable	Apply 7.0% of revenue in the first year, improving to 5.0% by the mature year.	Treating fuel like fixed overhead instead of a service-volume expense.
Payment Processing Fees	Variable	Apply 2.5% of revenue in the first year, declining to 2.0% by the mature year.	Forgetting card fees and overstating contribution margin on every booking.
Detailing Technician Wages	Semi-fixed	Add labor in hiring steps: 1.0 FTE in the first year to 5.0 FTE by the mature year.	Modeling labor as fully variable and missing the cash hit when hiring ahead of demand.
Annual Marketing Budget	Semi-variable	Scale spend from $10,000 in the first year to $75,000 by the mature year as customer acquisition grows.	Using CAC alone and ignoring the actual marketing cash budget.

How does break-even shift between a lean launch, the base case, and a fuller mobile detailing setup?

Scenario table

Lean volume keeps risk high because fixed costs outrun contribution. The base case gets close to cover, and the expanded case turns the added overhead into a modest cushion only if ticket size and route use hold up.

These are planning assumptions for model use, not guarantees for actual results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch test	$13,500	$2,700	$16,667	80.0%	-$5,867	Useful for testing demand, but still below cover.
Base operating case	$20,235	$3,541	$16,667	82.5%	$27	Near break-even, so small misses can push it red.
Expanded service mix	$34,052	$5,584	$23,333	83.6%	$5,135	Adds a cushion, but only with steady higher-ticket work.

What breaks this break-even plan for mobile car detailing?

Stress test

This plan is balanced on a knife edge. The base case has only about a $27 cushion, and a 15% revenue drop, a 10% fixed-cost bump, or a move to 21.5% variable expenses can push it into a monthly loss.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$20,235	$27 cushion	Base case barely clears fixed costs.
Revenue shortfall	Revenue falls 15% to about $17,200.	$17,200	$2,477 gap	Fewer bookings break the plan fast.
Fixed-cost increase	Fixed costs rise 10% above plan.	$20,235	$1,667 gap	Extra overhead wipes out the cushion.
Margin pressure	Variable expenses rise from 17.5% to 21.5% of revenue.	$20,235	$783 gap	Higher fuel or supply waste squeezes profit.
Combined pressure	Revenue falls 15%, variable expenses hit 21.5%, and fixed costs rise 10%.	$17,200	$4,831 gap	Slow sales plus cost creep creates a deep loss.

Can this mobile detailing plan clear break-even before you commit to the van?

Founder checklist

Before you buy the $80,000 van, prove the route can hold 142 jobs a month at the model’s pricing and still cover the $2,500 vehicle payment, insurance, and other fixed bills. If bookings are scattered, break-even slips fast.

1Demand proof142 jobs/mo

Prove you can keep 142 jobs a month inside one tight service radius before buying the van, because scattered stops burn time and fuel.

2Fixed load$22.1K/mo

Here’s the quick math: $6,250 of overhead plus $15,833 of Year 1 payroll is about $22.1K a month before any variable costs.

3Margin mix82.5% CM

Year 1 variable costs are about 17.5% of sales, so you keep roughly 82.5% contribution before payroll and overhead; if pricing slips, break-even moves fast.

4Hire timingMonth 13

Keep the customer service and scheduler hire at Month 13 and add more labor only when booked volume can absorb payroll, or headcount eats margin.

5Cash trough$729K

Keep enough cash after the $80,000 van, $15,000 equipment, and $5,000 supplies buys, because the model’s low point still lands in Month 16.

6CAC test$50 CAC

Test customer acquisition at $50 CAC before you scale the $10,000 first-year marketing budget, and get booking and scheduling live first so jobs do not bunch up.
