Food Truck Costs: Why Low Rent Buys You a Higher Food Cost

August 10, 2026 · 4 min read

Food trucks can run food costs of 30–38% — well above a bricks-and-mortar target — because occupancy is 3–6% of sales instead of 9–12%. The saved rent buys you a bigger portion or a lower price, and the costs that replace it are fuel, commissary, permits and event fees.

Where the money goes instead of rent

The same $18,000 month, two formats
Line	Bricks & mortar	Food truck
Rent / commissary	10.5%	4.5%
Utilities	3.0%	1.0%
Fuel & vehicle	0%	3.5%
Permits, licences, event fees	0.5%	4.0%
Maintenance	1.5%	3.0%
Total occupancy-equivalent	15.5%	16.0%

That's the honest version, and it surprises people: a truck's occupancy-equivalent is roughly the same as a small restaurant's. What actually differs is labour — a truck runs on two or three people — and that's where the room for a higher food cost comes from.

Worked example · Why 35% food cost works on a truck

Monthly sales: $18,000
Food cost at 35%: $6,300
Fully loaded labour at 26%: $4,680
Prime cost: $10,980 · 61.0%
Occupancy-equivalent at 16%: $2,880
Other operating at 8%: $1,440
Left before owner pay: $2,700 · 15.0%

A 35% food cost that would be alarming in a full-service restaurant is comfortable here, because labour is ten points lower. This is why borrowed benchmarks mislead — derive your own from your own structure.

The truck-specific numbers to track

Revenue per service, not per month. A truck's economics are decided event by event. A pitch that costs $250 and does $900 is a different business from one that costs $75 and does $700.
Break-even per service. Fixed costs per service ÷ contribution margin ratio. If you don't know this number you cannot evaluate a booking — the break-even calculator does it.
Waste per service. Prepping for a queue that doesn't come is the defining truck risk, and it's entirely a forecasting problem.
Fuel and generator per service. Small per event, meaningful annually, and almost never costed.

Worked example · Evaluating a booking

Event fee: $250
Fuel + generator: $45
Labour, 3 staff × 7 hrs: $420
Fixed cost of the service: $715
Average ticket: $14.50
Contribution margin ratio at 34% food cost: 66%
Break-even: 75 covers

If the pitch realistically does 60 covers, that booking loses money regardless of how busy it feels. Run this before saying yes, not after.

The three traps

Menu too long for the space. Every extra SKU is prep, storage you don't have, and waste. Trucks that work usually sell four to six things.
Pricing against restaurants. Guests expect a truck to be cheaper, which is a real constraint — but your portions are also usually larger. Price against your contribution target, not against the restaurant across the road.
Not costing the commissary. Prep kitchen rent, storage and cleaning are real occupancy and belong in the number. Leaving them out makes a truck look more profitable than it is.

Why short menus win on a truck

The constraint isn't taste, it's the physics of the box. Every additional item competes for prep time, cold storage and holding space that a truck doesn't have — and the cost shows up as waste rather than as an obvious line item.

Worked example · The cost of two extra menu items

Additional SKUs required: 7
Additional prep time per service: 35 min at $22/hr loaded
Additional cold storage displaced: ≈15% of capacity
Waste on the two items, typical: 18% of their food cost
Combined weekly sales of the two items: $620
Net weekly contribution: ≈$140, before the displacement cost

Two items earning $140 a week while consuming 15% of your cold storage is usually a bad trade — the storage they displace would have carried more of the four things that actually sell.

Forecasting is the truck's real skill

A restaurant with a bad forecast has a slow night. A truck with a bad forecast has prepped food it cannot carry to the next service and cannot store. That asymmetry is the defining operational risk of the format.

Log every service: date, pitch, weather, hours, covers, revenue. Twenty services is enough to forecast from, and there is no substitute for your own history.
Prep in tiers. A base batch that always sells, plus a second batch you only start if the queue justifies it. Slower per unit, dramatically less waste.
Track waste per service as a percentage of what you prepped, not of what you sold. Prepping for 120 and selling 80 is a 33% overproduction, and it will not be visible in a food cost percentage.
Weather is a real input. Record it; you'll find the correlation is stronger than you expect and it becomes a genuine planning tool.

Know your break-even before you take the booking.
