Planning checklist for a 100-person catered event
4–6 months before (or earlier for weekends)
Confirm the date, venue, and approximate guest count. Begin contacting caterers for availability.
2–3 months before
Get itemized quotes from 3 caterers. Confirm what is and is not included in each quote. Check for minimum spend requirements.
6–8 weeks before
Sign the contract and pay the deposit. Finalize the menu selection. Confirm dietary restrictions.
2–3 weeks before
Give the caterer a guest count update. Confirm setup and arrival time, parking for the catering van, and kitchen access.
1 week before
Final headcount. Reconfirm dietary accommodations. Verify rental delivery schedule if separate from catering.
Day before
Confirm arrival time and point of contact. Verify gratuity policy — most caterers auto-add 18–22%.
Frequently asked questions
How much does catering for 100 people cost?
Catering for 100 people costs approximately $3,000–15,000 total, depending on service style. A drop-off buffet lunch costs $2,000–4,000 ($20–40/person). A buffet dinner with setup staff runs $4,000–7,000 ($40–70/person). A plated sit-down dinner with full service costs $8,000–15,000 ($80–150/person). Wedding catering for 100 guests typically starts at $10,000 all-in and can reach $20,000+ with bar service, rentals, and gratuity.
How much food do you need for 100 people?
For a buffet dinner serving 100 people, plan approximately 6–8 oz of protein per person (37–50 lbs total), 4–5 oz of each side dish (25–30 lbs each), one dinner roll per person, and salad for 80–85% of guests (buffets always have waste). For a plated dinner, portion control is easier: 6–8 oz protein, 4–5 oz starch, 3–4 oz vegetables per plate. Add 5–10% overage for buffets; plated dinners can order closer to exact count.
How many servers do you need for 100 people?
For a buffet with 100 guests, plan for 3–4 servers to run food stations, clear plates, and handle drinks. For a plated sit-down dinner for 100, plan for 6–8 servers (1 per 12–15 guests) plus a captain. For a cocktail reception with 100 guests, plan for 4–5 servers passing appetizers and 2–3 bar staff if you have a bar. Most full-service caterers include staffing in their per-person price; verify this before comparing quotes.
What is the cheapest way to cater for 100 people?
The most cost-effective options for catering 100 people are: (1) Drop-off catering from a restaurant or catering company ($20–35/person, no service staff); (2) Food truck catering ($15–30/person for simple formats); (3) DIY catering from a wholesale club (Costco, Sam's Club — food only, no service, roughly $10–20/person in food cost); (4) Hiring a caterer for food delivery only and using volunteers to serve. Full-service sit-down catering is always the most expensive option.
How far in advance should you book catering for 100 people?
Book catering for a 100-person event at least 4–8 weeks in advance for a weekday corporate event, and 4–6 months in advance for a wedding or weekend social event. Popular caterers book out 6–12 months for peak season dates (May–October). The more guests and the higher the service level, the earlier you should book. Most caterers will hold a date with a small deposit (10–25%) and finalize the menu and final headcount closer to the event.
