Which expenses are fixed and which move with sales for a custom food truck builder?

Cost classification

If you treat chassis and labor like overhead, break-even looks safer than it is. Use fixed overhead for monthly commitments and variable rates for each build, so contribution margin reflects the real job mix.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop rent	Fixed	Include the $6,000 monthly rent in overhead from Month 1 through Month 60.	Treating rent as a project expense.
CEO Founder salary	Fixed	Include the $120,000 annual salary in recurring payroll overhead.	Excluding owner pay from break-even.
Vehicle chassis	Variable	Assign per build: $5,000 small, $7,000 medium, and $10,000 large.	Spreading chassis spend evenly across all projects.
Stainless steel	Variable	Assign by truck size: $2,000 small, $3,000 medium, and $5,000 large.	Using one average for small and large builds.
Direct fabrication labor	Variable	Tie labor to scope: $1,500 small, $2,000 medium, and $3,000 large.	Burying project rework in overhead.
Sales commissions	Variable	Apply 2.0% of first-year revenue, including trucks, upgrades, and consults.	Forgetting commission on upgrade packages.
Utilities workshop office	Semi-variable	Use the $1,500 monthly base plus workshop utility rates tied to revenue.	Treating all utilities as fixed.
Administrative Assistant payroll	Semi-fixed	Add the $45,000 annual role when staffing starts in Month 13.	Hiring before backlog supports the added payroll.

How does break-even shift from a lean launch plan to a full build-out?

Scenario table

The lean case is close to the edge because workshop and payroll costs start fast. As revenue moves from Year 1 to Year 3, the higher run-rate gives more cushion and lowers break-even risk.

Forecast cases only; actual bookings, build timing, and labor use can move results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean case, Year 1	$68.7k	$12.4k	$54.0k	81.9%	-$4.5k	Tight; launch delays can push break-even back.
Base case, Year 2	$114.2k	$20.0k	$60.7k	82.5%	$24.0k	Break-even clears with a modest cushion.
Full case, Year 3	$164.4k	$27.6k	$65.7k	83.2%	$58.6k	Healthy cushion if bookings stay on plan.

What breaks first if revenue slips or overhead stays high?

Stress test

This plan has thin slack. At about $687k in monthly revenue against about $540k of fixed payroll and overhead, a 10% revenue dip or a 10% overhead jump quickly turns the cushion into a gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$659k	$28k cushion	There is only a small buffer above break-even.
Revenue shortfall	Monthly revenue drops 10% to $618k.	$659k	$41k gap	A modest demand dip wipes out the cushion.
Fixed-cost pressure	Fixed overhead rises 10% to $594k.	$725k	$38k gap	Higher payroll or shop costs push break-even up fast.
Margin pressure	Contribution margin falls 5 points to 76.9%.	$702k	$15k gap	Rework or material creep cuts the cushion sharply.
Combined pressure	Revenue drops 10%, fixed load rises 10%, and margin falls 5 points.	$772k	$154k gap	Delayed deposits, permit delays, or rework can stack into a large miss.

What should you verify before you sign the shop lease for a custom food truck build?

Founder checklist

Don’t sign yet. Prove the Year 1 mix, because break-even lands in Month 14 and cash bottoms at $873K in Month 13; if the pipeline can’t support that ramp, the shop and hires come too early.

1Year 1 Mix$824K

Verify signed demand can reach 4 small builds, 2 medium builds, 1 large build, 5 upgrades, and 3 consults before you lock the lease.

2Fixed Load$648K

Check that annual payroll plus workshop overhead stays near this level, because the first-year build plan has to carry that fixed base.

3Margin Check83% CM

Confirm unit build costs and sales fees stay close to model so each truck and package still leaves enough contribution to fund the workshop.

4Staff RampMonth 13

Delay the administrative assistant until Month 13 unless backlog is already full, and keep skilled labor aligned with the 2-to-4 FTE ramp.

5Cash Cushion$873K

Hold at least this much cash through Month 13, because the plan still shows a Year 1 EBITDA loss of $54K before the ramp turns up.

6Launch DemandDeposits set

Set a deposit policy before ordering chassis or equipment, and lock vendor terms for chassis, stainless steel, kitchen equipment, and electrical systems.
