Formula Used

The number of trucks required is calculated using the following formula:

Number of Trucks = (Number of Guests × Service Duration) ÷ (Service Capacity × Truck Efficiency)

Where:

Service Capacity is based on standard In-N-Out menu items (200 items per hour per truck)
Truck Efficiency accounts for setup time and breaks (80% for standard service, 90% for premium)

Worked Examples

Example 1: Corporate Event

For a 4-hour corporate event with 500 guests:

Number of Trucks = (500 × 4) ÷ (200 × 0.8) = 3.125 → 4 trucks needed

Example 2: School Fundraiser

For a 3-hour school fundraiser with 300 guests:

Number of Trucks = (300 × 3) ÷ (200 × 0.9) = 1.8 → 2 trucks needed
