Which mobile RV repair expenses stay fixed, and which rise with service calls?

Cost classification

Break-even is only useful if each expense behaves the right way in the model. Treat fuel, parts, and card fees as job-linked, while rent and core software stay fixed within the monthly planning range.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $1,500 per month as fixed overhead before any service call revenue.	Spreading rent across jobs and making break-even look easier at low volume.
Business Insurance	Fixed	Use $800 per month as a required operating expense in every month.	Dropping insurance from break-even because it does not tie to a single repair.
Software Subscriptions	Fixed	Use $400 per month for booking, customer management, and accounting systems.	Modeling software as a per-job fee when the plan shows a stable monthly charge.
Owner/Operator	Semi-fixed	Use the $80,000 annual salary as recurring capacity that does not move one-for-one with jobs.	Treating owner labor as free and overstating the first operating year margin.
Lead RV Technician	Semi-fixed	Add capacity in steps: 1.0 FTE early, 2.0 FTE in Year 3, and 3.0 FTE in Year 5.	Adding technician payroll as if it rises smoothly with every service call.
Parts and Supplies	Variable	Apply 15% of revenue in the first year, falling to 11% by Year 5.	Putting parts into fixed overhead and hiding margin pressure from larger repair jobs.
Technician Vehicle Fuel	Variable	Apply 5% of revenue in the first year, declining to 3% by Year 5.	Treating fuel like rent even though route distance and job count drive it.
Annual Marketing Budget	Semi-variable	Use the planned spend, starting at $10,000 in the first year, and test it against $150 CAC.	Assuming marketing is fully fixed while customer acquisition changes with lead volume.

How does break-even shift from lean to full utilization in mobile RV repair?

Scenario table

Break-even moves fast with route fill and job mix. With fixed monthly costs near $191k, the base case sits close to break-even, while lean volume stays below it and full utilization builds a clear cushion.

Planning cases only; results depend on route density, billable hours, and how quickly jobs are filled.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean mobile route	$178k	$45k	$191k	74.7%	-$58k	Still below break-even, so fill rate is the main risk.
Base route build	$258k	$66k	$191k	74.4%	$1k	Near break-even, so small drops in volume can turn it negative.
Full route density	$396k	$101k	$191k	74.5%	$104k	Comfortably past break-even, with enough cushion to absorb slow weeks.

What breaks the break-even plan for mobile RV repair?

Stress test

The plan is tight in the base case, so small slips in call volume, parts margin, fuel, or insurance can push it below break-even. The combined downside is the real danger: it turns a near-zero result into about a $59,000 gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$256,000	$0 gap	Base case leaves almost no cushion.
Revenue shortfall	Revenue falls 15% to about $217,600.	$217,600	$29,000 gap	Fewer service calls create a fast gap.
Fixed-cost pressure	Fixed costs rise 10% to about $210,100.	$256,000	$19,000 gap	Insurance or rent hikes hit break-even quickly.
Margin pressure	Variable expenses rise 5 points to 30.5%.	$256,000	$13,000 gap	Weak parts markup cuts cash left over.
Combined pressure	Revenue falls 15%, fixed costs rise 10%, and variable expenses rise 5 points.	$217,600	$59,000 gap	Volume and cost pressure together break the plan.

What should you verify before buying the next service vehicle for mobile RV repair?

Founder checklist

Before you add trucks, tools, or staff, prove the service area can support the ticket mix and margin that hit break-even. This model does not reach break-even until Month 19, and it needs about $609k of minimum cash, so early scale has to fit the cash curve.

1Break-Even Load$256k/mo

Verify the service area can support the $256k monthly break-even load and Year 1 CAC near $150 before you scale ads or crews.

2Buildout Gate$143k capex

Confirm the first vehicle, second vehicle, tools, diagnostics, parts, and booking build are justified by booked work before you lock the spend.

3Ticket Floor$435 / $295 / $325

Hold on-site repair, maintenance, and inspection pricing near $435, $295, and $325 after discounts so the average job still carries margin.

4Route Costs8% variable

Map the service radius so 5% fuel and 3% usage-based maintenance stay in line, because long drives can erase job contribution.

5Staffing RampMonth 13

Test dispatch flow before the junior technician starts in Month 13, and only add labor when booked jobs cover it.

6Cash Cushion$609k + $3.85k/mo

Keep enough working capital for the Month 19 trough and the $3.85k monthly overhead, because break-even lands in Month 19.
