The menu price is only one part of the catering bill
Use the contract, not a generic formula, to understand what is taxable and where service charges apply. This calculator lets you replace the percentages with the numbers your caterer actually uses.
Adult meals
Track the full adult guest count expected for dinner.
Children
Use the caterer’s actual age rules and menu pricing.
Vendor meals
Photo, video, planners, entertainment and other teams may need meals.
Beverages
A per-guest estimate makes the effect of guest count visible.
Late-night food
Useful for long receptions, but calculate it as a separate choice.
Rentals & fixed fees
Linens, tableware, delivery and service costs can sit outside menu pricing.
Buffet, plated and family-style meals create different operational needs
Plated
Can feel formal and controlled, with more need for accurate entrée choices and service staffing.
Buffet
Can offer variety, but line flow, table release and room layout matter.
Family style
Creates a shared-table experience and needs enough table surface for serving dishes.
Stations
Can support movement and variety, but require space, power and staffing.
Cocktail reception
Can work beautifully when food quantity and seating are sufficient for the full event length.
One guest can affect more than one line item
Adding guests may increase meals, beverages, rentals, table count, staffing and sometimes the room configuration. Use the seating planner and catering calculator together before finalizing numbers.
- Confirm the final-count deadline in the contract
- Keep children and vendor meals separate
- Ask whether meals are required for vendor teams
- Check whether service charge and tax apply to every line
- Recalculate after the seating list is close to final
