3 Main Factors That Impact Catering Costs

When calculating your total event catering budget, consider these three core variables:

1. Menu Selection & Proteins

Simple sandwich platters, wrap trays, and pizza packages carry lower food costs than high-end proteins like beef tenderloin, salmon, or seafood spreads. Offering popular crowd-pleasers like Mediterranean spreads, fresh salad bars, and chicken entrees allows you to deliver high quality while staying budget-friendly.

2. Service Style (Drop-Off vs. Full-Service)

• Drop-Off Delivery Catering: The most budget-friendly option. Food arrives heated, boxed or plated in trays, and ready to serve.

• Full-Service Catering: Includes setup, servers, bartender staffing, table clean-up, and rental equipment (linens, dinnerware, chafing dishes). Staffing adds hourly labor costs to your bill.

3. Dietary Accommodations & Variety

Accommodating dietary restrictions (vegan, vegetarian, gluten-free, dairy-free) can sometimes increase catering costs if forced to place separate orders across multiple vendors.

Frequently Asked Questions About Event Catering Costs

How much food do I need to feed 100 guests?

For a standard meal, plan on roughly 5 to 8 oz of protein, 4 to 6 oz of side dishes, and 1 to 2 servings of salad or bread per person. For cocktail parties without a main meal, order 8–12 appetizer pieces per guest.

Is drop-off catering cheaper than full-service?

Yes. Drop-off catering eliminates staff labor hours, server tips, and equipment rental fees, typically saving you 30% to 50% compared to full-service catered events.

How far in advance should I book catering for 100 people?

For corporate lunches and small events, booking 3 to 7 days in advance is usually sufficient. For weddings or holiday peak seasons, aim to book 1 to 3 months prior.
