How to Calculate Food Truck Event Profit

The formula

Food truck event profit reduces to a single line: Revenue − (Food Cost + Labor + Vendor Fee + Revenue Share + Travel) = Profit. Every input maps to a number on the vendor packet or your own profile, and every output drives a go/no-go decision.

Step 1 — Forecast revenue

Start with expected attendance from the organizer, then discount it 20–30% for first-year events. Multiply by your realistic capture rate: 4–6% at saturated festivals, 8–10% at brewery nights or markets with low cuisine overlap. Multiply orders by your average ticket — including drinks and sides if you typically up-sell.

Quick sanity check

Most single-window trucks max out around 60–90 paid orders per hour. If your forecast assumes more than that, your revenue is inflated unless you add a second window or a runner.

Step 2 — Subtract food cost

Use your truck's actual COGS percentage, not a generic 30%. Quick-serve items typically run 25–30%, while protein-heavy plates run 32–38%. A single point of food cost on a $4,000 day is $40 — these add up across a season.

Step 3 — Subtract labor

Compute labor as staff × service hours × loaded wage. Loaded means payroll taxes, workers' comp, and any guaranteed minimum. Don't forget load-in/load-out hours — they're often 25–40% on top of service time.

Step 4 — Subtract vendor fee + revenue share

Flat fee goes in once. Revenue share is a percentage of gross revenue — read the vendor agreement carefully, because some organizers calculate share before food cost (worse for you) and some after.

Step 5 — Subtract travel

Use $0.85/mile round trip as a conservative number — it covers fuel, wear, and amortized maintenance. For events more than 100 miles out, add a hotel night if you can't drive both ways in one day.

Worked example

Attendance: 3,500 · Capture: 8% · Ticket: $14 → 280 orders, $3,920 revenue
Food cost 28% → $1,098
3 staff × 6 hrs × $22 loaded → $396 labor
Vendor fee: $450
Revenue share: 0%
40-mile one-way travel: 80 mi × $0.85 → $68

Total cost: $2,012. Profit ≈ $1,908 at a 49% margin. Verdict: take it.

What this formula doesn't capture

Weather risk (outdoor events lose 30–50% on rainy days)
Competing trucks added after you commit
Surprise organizer fees (power, water, generator, trash deposit)
Capacity limits on power/water that force a slower menu

FRUCKOS factors these qualitative risks into its scoring and surfaces them on the event detail page before you commit.
