A fleet management service needs about $141K in monthly revenue to break even under the Year 1 assumptions Here’s the quick math: fixed monthly overhead is $1156K, variable expenses are 18% of revenue, so contribution margin is 82% At an estimated $5117 per managed vehicle per month, that equals roughly 2,755 managed vehicles The model reaches break-even in Month 31, with minimum cash of -$126M in Month 30

Break-even chart Revenue Total costs
Which fleet management expenses are fixed, and which move with sales?
Cost classification
Break-even only works if fixed commitments and revenue-linked costs are split cleanly. Here, wages, rent, hosting, support tools, and marketing set the monthly hurdle, while hardware, connectivity, processing, and installation reduce contribution margin.
Expense
Cost
Break-Even Treatment
Common Mistake
Year 1 wages
Semi-fixed
Use about $66.3K per month in the fixed base, based on $795K annual payroll divided by 12.
Treating planned payroll as optional after customer contracts are signed.
Office Rent
Fixed
Include $8K per month in fixed operating expenses for the full model period.
Leaving rent out because it does not tie to vehicle count.
Cloud Hosting and Data Processing
Semi-fixed
Start with $6K per month, then review capacity steps as vehicle data volume grows.
Modeling all hosting as a simple percent of revenue.
Customer Support Platform
Semi-fixed
Start with $1.2K per month and add step increases when support seats or ticket volume require upgrades.
Assuming support tools stay flat at every customer count.
Annual Marketing Budget
Fixed
Include the first year budget as about $29.2K per month, calculated from $350K divided by 12.
Treating committed marketing as discretionary after the sales plan starts.
Telematics Hardware Procurement
Variable
Use 8% of revenue in the first year as a direct reduction to contribution margin.
Putting hardware procurement in fixed overhead instead of revenue-linked COGS.
Connectivity Data Plans and SIM Costs
Variable
Use 5% of revenue in the first year because usage scales with active vehicles.
Forgetting that each connected vehicle adds ongoing data plan expense.
Payment Processing and Billing Fees
Variable
Use 1.5% of revenue across the model period as a sales-linked fee.
Using gross revenue in break-even math without subtracting billing fees.
How does break-even change from a lean fleet setup to a base case and a fuller build?
Scenario table
The lean case stays far below fixed overhead, the base case lands near break-even, and the full case creates a real cushion. The shift comes from higher recurring fees while variable costs hold at about 18% of revenue.
These are planning assumptions built from the model’s Year 1 pricing mix and 18% variable expense load, so they show break-even direction, not a guarantee.

What pushes this fleet management plan below break-even?
Stress test
The plan only breaks even at about $1,410K in annual revenue, so small misses matter. A 10% revenue drop, higher install or support effort, or a 10% overhead lift can each turn EBITDA negative fast.

Can you prove break-even before you lock in offices, devices, and hiring?
Founder checklist
Before you commit, prove the pipeline, pricing, and cash math with real buyers. This model only clears break-even if demand, install capacity, and acquisition costs hold long enough to get past Month 31.
1Pipeline proof2,755 vehicles
Verify you can line up about 2,755 managed vehicles and hold about $51.17 per vehicle each month across the base plan and add-ons, because that is the revenue base behind break-even.
2CAC test$150 CAC
Test whether sales can close near the $150 customer acquisition cost before spending the $350K Year 1 marketing budget, or the launch math breaks first.
3Margin mix82% CM
Check that hardware, connectivity, billing, and field support stay near 18% of revenue so contribution margin stays around 82% before fixed overhead.
4Run rate$1.07M/yr
Confirm the company can carry about $1.07M a year in payroll plus fixed overhead before more office space, devices, or support headcount, because that burn has to be funded by real demand.
5Install load0.5 FTE
Verify a half-time field technician can keep installs and support on schedule at launch, or device rollout will slow and push breakeven back.
6Cash runway-$1.26M
Plan funding to cover the trough through Month 31, because minimum cash reaches about negative $1.26M in Month 30 and first-year capex totals about $365K.
