Formula: Grand Total = (Food + Drinks) x Guests + Staff Costs + Service Charge + Tax
Worked example — Grand Total: ~$21,812 | Per person: ~$182 (all-in)
Formula
Grand Total = (Food + Drinks) x Guests + Staff Costs + Service Charge + Tax
Wedding catering costs are calculated by multiplying per-person food costs (base price plus additional courses) and drink costs by guest count, then adding staffing costs (based on service style ratios), a 20% service charge, and 8% tax. Plated dinners require more staff (1:10 ratio) than buffets (1:20).
Worked Examples
Example 1: 120-Guest Plated Wedding Dinner
Problem:120 guests, plated 3-course dinner with open bar.
Solution:Food per person: $55 + (2 extra courses x $15) = $85 Drink per person: $35 (open bar) Food total: 120 x $85 = $10,200 Drink total: 120 x $35 = $4,200 Staff: 12 servers + 3 bartenders = $3,150 Service charge (20%): $2,880 Tax (8%): $1,382 Grand total: $21,812
Result:Grand Total: ~$21,812 | Per person: ~$182 (all-in)
Frequently Asked Questions
How much does wedding catering cost per person?
Wedding catering typically costs $70-$150 per person for a full dinner with drinks. A plated dinner runs $70-$120 per person, buffet-style $50-$90, and food stations $65-$110. Open bar adds $35-$75 per person, limited bar (beer/wine) adds $20-$35, and cash bar costs only $5-$10 per person for setup. These costs vary significantly by location — major cities like New York or LA can be 50-100% higher than rural areas. Service charges (18-22%) and tax add another 25-30% to the base costs.
Is plated or buffet cheaper for a wedding?
Buffet service is typically 20-30% cheaper than plated dinner per person because it requires fewer servers and simpler logistics. However, buffets can lead to higher food waste and require more food to keep displays full. Food stations fall between the two in cost. Plated dinners are more elegant and allow better portion control. For large weddings (200+ guests), buffet savings become more significant. For smaller intimate weddings (under 75 guests), plated service is often comparable in cost and provides a more upscale experience.
How many servers do I need for my wedding?
The staffing ratio depends on service style: Plated dinner needs 1 server per 10 guests, buffet needs 1 per 20 guests, and food stations need 1 per 15 guests. Additionally, plan for 1 bartender per 50 guests for an open bar (1 per 75 for beer/wine only). For a 150-guest plated dinner with open bar, you'd need approximately 15 servers and 3 bartenders. A wedding coordinator/captain is also recommended for events over 100 guests. More staff ensures smoother service but increases costs.
What is included in the service charge for catering?
The service charge (typically 18-22% of the food and beverage total) covers the catering company's operational costs including staff wages, equipment rental, setup and breakdown, linen service, and coordination. This is different from a gratuity/tip. Some venues include the service charge in their per-person price, while others add it separately. Always clarify whether the service charge goes to the staff as a tip or to the company. A separate gratuity of $50-$100 for the catering captain and $20-$50 per server is customary.
What is a guaranteed guest count and how does it affect the final bill?
The guarantee is the headcount you confirm to the caterer a set number of days before the wedding, commonly three to seven. It becomes a floor: you pay for that many covers even if fewer people arrive, while extra guests above it are billed at the per-plate rate and may not have a seat. Set the guarantee from confirmed RSVPs plus a small cushion rather than from the number of invitations you posted.
Do I pay full price for vendor meals and children's plates?
No. Photographers, videographers, the band or DJ and the planner usually have a contractual meal clause, and caterers price those vendor meals below the guest plate because they are simpler and served at a different time. Children's plates are also discounted and portioned smaller. Count both groups separately from your adult guest number so the per-person figure Wedding Catering Calculator produces is not inflated by people eating a cheaper menu.
How much food should the cocktail hour add on top of dinner?
Plan roughly four to six hors d'oeuvre pieces per guest for a one-hour cocktail reception that precedes a full dinner, and eight to twelve pieces per guest if passed canapes are replacing a seated meal. Passed service controls consumption better than a static display, which guests graze continuously. Cocktail hour is billed on top of the dinner plate price, so add it to the food line before applying the service charge.
What is a cake-cutting fee and can I avoid it?
If you bring in a cake from an outside baker, many venues and caterers charge a cake-cutting fee per slice to cover plating, china, and the staff time to portion and serve it. Ordering dessert through the caterer usually waives it. The same logic applies to corkage on outside wine. Both charges are negotiable during contract talks and are far cheaper to remove then than to dispute on the final invoice.
How do I estimate quantities for a beer and wine bar?
A workable planning rule is one drink per guest in the first hour and about half a drink per guest per hour after that, with roughly 60% wine and 40% beer at a typical evening reception. A 750 ml bottle of wine pours five standard five-ounce glasses. Multiply out to get bottles, then round up by a case, because running dry mid-reception costs more in goodwill than the surplus costs in cash.
When should the tasting happen and when does the menu lock?
Book the tasting after the contract is signed but far enough ahead that changes are still free — commonly three to five months out. Use it to test seasoning, portion size and how the dish holds after plating, not just flavour. Menus typically lock about a month before the wedding, because the caterer orders produce and protein against your guaranteed count and cannot absorb late substitutions without a repricing.
