Which dump truck expenses are fixed, variable, semi-variable, or semi-fixed for break-even?

Cost classification

Break-even is only useful if each expense behaves the way the model says it does. Here, fuel, materials, repairs, and cargo insurance move with revenue, while leases and core software hold steady.

Expense	Cost	Break-Even Treatment	Common Mistake
Depot/Yard Lease	Fixed	Model at $2,000/month from Month 1 through Month 60.	Spreading the lease by truck and making it look volume-based.
Office Rent	Fixed	Model at $500/month across the planning period.	Removing it from break-even because it feels small.
Utilities for Office and Yard	Semi-variable	Start with the $350/month base, then review usage as yard activity rises.	Treating the full utility bill as fixed when operating hours expand.
Software Subscriptions for GPS, Scheduling, and Accounting	Fixed	Model at $400/month unless the fleet plan adds priced seats or vehicles.	Linking the full subscription directly to each hauling job.
Fuel Costs	Variable	Model as 14.0% of revenue in the first year, falling to 11.0% by the fifth year.	Using a flat monthly fuel budget instead of tying it to hauled work.
Disposal and Material Purchase Costs	Variable	Model as 6.0% of revenue in the first year, falling to 5.0% by the fifth year.	Forgetting that material sales and debris jobs carry direct job-level costs.
Truck Maintenance and Repairs	Variable	Model as 4.0% of revenue in the first year, falling to 3.0% by the fifth year.	Treating all repairs as fixed even though miles, loads, and wear drive spend.
Driver Payroll	Semi-fixed	Model drivers in steps: two drivers in the first year, a third in Year 2, and a fourth in Year 3.	Averaging driver pay across all jobs instead of adding payroll by fleet stage.

How does break-even move as the dump truck operation scales from lean to full?

Scenario table

Break-even rises as the fleet adds payroll and the fixed base gets heavier, even though the margin gets better. So the real test is whether dispatch volume grows fast enough to clear a higher monthly floor.

Planning assumptions only; actual demand, pricing, and fuel costs can move the break-even point.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean case, Year 1 structure	$5.5k	$1.5k	$26.6k	73.5%	$-22.5k	Revenue is far below the $36.2k floor, so underused trucks are the main risk.
Base case, Year 3 structure	$6.6k	$1.5k	$37.2k	76.7%	$-32.1k	A better mix helps, but the fixed base still points to a roughly $48.5k floor.
Full case, Year 5 structure	$7.7k	$1.6k	$42.4k	79.0%	$-36.3k	The maintenance hire improves uptime, but it also lifts the floor to about $53.7k.

What breaks the break-even plan?

Stress test

The base plan has no cushion, so a 10% drop in hauling demand or a 10% jump in fixed costs quickly turns into a $27K to $37K monthly gap. Fuel, repair, and insurance pressure are the first places the break-even math breaks.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$361K	$0 cushion	Baseline is already at break-even.
Revenue shortfall	Hauling demand falls 10%.	$361K	$27K gap	A small sales miss pushes cash negative.
Fixed-cost increase	Fixed monthly costs rise 10%.	$398K	$37K gap	Overhead moves break-even up fast.
Margin pressure	Variable expenses rise to 315%.	$388K	$27K gap	Fuel or repairs can erase the cushion.
Combined pressure	Demand falls 10%, fixed costs rise 10%, and variable expenses rise to 315%.	$430K	$69K gap	No cushion before fuel, repair, or insurance shocks.

What must a dump truck founder verify before buying the first $150K trucks?

Founder checklist

Before you buy trucks or sign the yard, verify committed hauling work, early truck utilization, payroll coverage, and cash. The model reaches break-even in Month 34, but it still bottoms at -$230K in Month 38, so treat the plan as a test, not a promise.

1Demand Proof$150K each

Verify signed hauling work before you commit to the first $150K truck, because idle equipment burns cash fast.

2Fixed Load$4.9K/mo

Verify the yard lease, office rent, utilities, fixed insurance, software, professional services, and supplies fit the monthly base before the first load ships.

3Launch Demand2 trucks

Verify the first two trucks can stay busy before the Month 9 third-truck spend, because weak early utilization makes the next capex harder to recover.

4Payroll Ramp$255K/yr

Verify work volume can support the $90K owner/operator, $45K dispatcher, and two $60K drivers before you add more headcount.

5Margin Check73.5% CM

Verify Year 1 contribution margin (cash left after variable job costs) stays near 73.5% after 14.0% fuel, 6.0% disposal/material costs, 4.0% maintenance, and 2.5% variable insurance.

6Cash Cushion-$230K

Hold cash for the modeled minimum of -$230K in Month 38 and treat Month 34 break-even as timing, not a funding promise.
