Break-even revenue equals fixed monthly costs divided by contribution margin ratio Using $103,008 in fixed monthly costs and 105% variable expenses, this transportation and shipping company needs about $115,093 in monthly revenue to break even The model shows break-even in Month 4, with minimum cash need of $490,000 in Month 5 Fuel, insurance, driver pay, maintenance, and empty-mile risk can still move the break-even point if route costs rise or utilization falls

Break-even chart Revenue Total costs
Which expenses stay fixed and which move with shipment volume?
Cost classification
Break-even is reliable only when fixed overhead and volume-linked costs are split cleanly. In the first year, $5,000 office rent is fixed, while payment gateway fees at 1.5% and sales commissions at 4.0% reduce margin on each shipment.

Cost
Break-Even Treatment
Common Mistake
Office Rent
Fixed
Include $5,000 per month in the fixed overhead base.
Tying rent to shipment growth instead of capacity.
General Software Licenses
Fixed
Include $1,500 per month before calculating contribution margin.
Deduct 1.5% of revenue in the first year from each transaction.
Ignoring processor fees until cash reconciliation.
Sales Team Commissions
Variable
Deduct 4.0% of revenue in the first year as volume grows.
Treating commissions like payroll instead of sales-linked spend.
Customer Support Per Shipment
Variable
Deduct 3.0% of revenue in the first year for shipment-level support load.
Modeling support as flat while orders rise.
Cloud Infrastructure Transaction Usage
Semi-variable
Model the first-year 2.0% usage charge against revenue, then watch base platform needs separately.
Calling all hosting fixed and overstating margin.
Operations Staffing
Semi-fixed
Add salary capacity in steps as operating load rises; Operations Manager staffing moves from 1.0 FTE to 2.0 FTE by the fifth year.
Assuming staffing scales smoothly with every shipment.
Fuel
Variable
Classify fuel with shipment activity when calculating margin per load.
Treating fuel as fixed and missing empty-mile margin risk.
How do lean, base, and full shipping cases change break-even?
Scenario table
Lean routing and weaker fill push break-even up fast. A denser lane network with more backhaul and repeat enterprise orders pushes it down, because the same $103,008 monthly overhead gets covered by more contribution dollars.
Planning assumptions only; actual break-even will move with freight mix, route density, and operating discipline.

What happens to break-even if shipments slow or costs spike?
Stress test
The base plan clears break-even with about $52.1k of monthly cushion at the stated run-rate. The real pressure points are empty miles, rate cuts, fuel spikes, insurance renewals, maintenance, labor, and low utilization.

What should you verify before committing to vehicles, drivers, or capacity?
Founder checklist
Don't commit to vehicles, drivers, or outside capacity until the Month 4 break-even target looks real. Here, the test is simple: can Year 1 demand cover about $73.8K a month in fixed load, keep acquisition spend inside the $350K budget, and leave the business with at least $490K cash?
1Cash Cushion$490K
Protect at least $490K cash, because minimum cash lands in Month 5 and the model only breaks even in Month 4.
2Fixed Burn$73.8K/mo
Confirm the monthly fixed load before signing leases or hiring, because the business starts at about $73.8K a month before variable volume helps.
3Buyer CAC$200
Test whether buyer acquisition stays near $200 in Year 1, because a higher cost would make the launch funnel too expensive to support break-even.
4Seller CAC$1,500
Keep seller acquisition near $1,500 in Year 1, because supply-side signups get expensive fast and can stall load coverage before break-even.
5Acquisition Budget$350K
Compare the $350K Year 1 acquisition budget to runway, and don't spend it ahead of dispatch workflow that can handle high-volume lanes.
6Margin Stack10.5%
Check that the $10 fixed commission and 8.0% variable fee can outrun the 10.5% direct cost stack; if not, volume will scale losses.
