Cost classification

Classifying costs correctly keeps Month 22 break-even honest: fixed overhead is $20,520/month before Year 1 payroll of $27,625/month and marketing of $3,750/month. Treat fuel and commissions as variable, not rent-like.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Rent and Storage Lot	Fixed	Include $8,500/month in fixed overhead from Month 1 through Month 60.	Tying lot rent to tow volume.
Fleet Insurance	Fixed	Include $4,200/month in fixed overhead for the planning range.	Modeling insurance as a per-job charge.
Fuel and Vehicle Operating Costs	Variable	Reduce contribution margin by the revenue-linked rate, starting at 18.0% in the first year.	Putting fuel into fixed overhead.
Driver Commission and Incentives	Variable	Apply the revenue-linked rate, starting at 3.5% in the first year.	Counting commissions as base payroll.
Payment Processing Fees	Variable	Apply the revenue-linked rate, starting at 2.8% in the first year.	Forgetting fees on card-paid jobs.
Vehicle Maintenance and Repairs	Semi-variable	Model the usage-linked repair load at 8.0% of revenue in the first year.	Treating all repairs as discretionary overhead.
Tow Truck Drivers Payroll	Semi-fixed	Start with 3.0 FTE at $12,000/month, then add capacity in staffing steps.	Making driver payroll fully variable.
Annual Marketing Budget	Semi-fixed	Use $3,750/month in the first year, then step up as the annual budget grows.	Blending marketing into permanent overhead.

How does break-even change across lean, base, and full tow truck service cases?

Scenario table

The base case lands at the $76,654 monthly break-even line, using about $51,895 in fixed monthly costs and a 67.7% contribution margin. Lean volume stays under that line, while the full case moves above it and starts to absorb fleet, staffing, and maintenance load.

Planning figures only; actual break-even will move with dispatch density, staffing, insurance, and truck uptime.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean dispatch-light case	$36,041	$11,646	$51,895	67.7%	-$27,500	Revenue stays well below break-even, so cash burn stays high.
Base break-even case	$76,654	$24,759	$51,895	67.7%	$0	At break-even, but any dip in dispatch volume turns negative.
Full dense-route case	$112,620	$36,392	$51,895	67.7%	$24,333	Revenue clears break-even and gives room for staffing and maintenance swings.

What breaks this tow truck break-even plan if calls slow or costs jump?

Stress test

The plan is fragile if paid calls fall, trucks sit idle, or costs rise. With minimum cash already at negative $95,000 in Month 26, even a small miss can turn break-even into a funding problem.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$76,654	$0 gap	No cushion, so any miss hits cash fast.
Revenue shortfall	Paid calls fall 10% below the current plan.	$76,654	$7,665 gap	Lower volume quickly eats the monthly cushion.
Fixed-cost pressure	Fleet insurance rises 20% to $5,040 per month.	$77,897	$1,243 gap	Insurance renewal pressure adds to heavy overhead.
Variable margin pressure	Fuel and repairs push variable costs to 37.3% of revenue.	$82,767	$6,113 gap	Small cost swings wipe out most of the margin.
Combined pressure	Paid calls fall 10%, insurance rises 20%, and variable costs rise to 37.3% of revenue.	$84,107	$15,118 gap	Volume loss and cost creep can force outside cash.

Can you prove break-even tow volume before you buy the fleet and open dispatch?

Founder checklist

Don’t buy the trucks or lock in dispatch coverage until permits, fleet insurance, storage access, and payment processing are in place. The model only works if early revenue can cover the launch build, the fixed load, and the first cash dip.

1Demand proof17/day

At the Year 1 mix, one paid job averages about $150.7, so 17 jobs a day is roughly $76.8K a month and lines up with break-even.

2Base load$51.9K/mo

Add the $45K Year 1 marketing budget and Year 1 payroll, and the business carries about $51.9K in monthly fixed load before variable costs.

3Margin check67.7% CM

Fuel, maintenance, driver commission, and processing take 32.3% of revenue, so price the $125, $95, $110, and $85 hourly lines to keep contribution margin near 67.7%.

4Staffing rampMonth 7

Hold assistant dispatchers, the mechanic, night supervision, and sales until call volume justifies them, because payroll jumps faster than demand if you hire ahead of route density.

5Cash cushion-$95K

The model bottoms out at about negative $95K in Month 26, so reserve cash has to survive the launch dip or the plan stalls before EBITDA turns positive.

6Launch capex$567K

Do not commit the $567K launch build until permits are cleared, fleet insurance is bound, storage lot access is ready, and payment processing has been tested.
