These are general planning estimates for one meal. Adjust for appetite, dietary needs, recipes, weather, serving style, and whether several proteins or sides will be offered.
How to use the estimate
Start with the expected number of adults and children, choose the closest menu style, and select an extra-food buffer. Ten percent is a practical starting point when the guest count is fairly reliable. Increase the buffer when attendance is uncertain or the food will be served for a long period.
Adjust for the way your family eats
- Reduce each protein when several main proteins will be served together.
- Increase drinks and ice for outdoor summer events.
- Confirm dietary needs before placing final orders.
- Ask caterers for their serving yields instead of relying only on package weight.
- Keep cold food cold and hot food hot; use appropriate food-safety guidance.
Avoid buying for the invitation list
Use confirmed household registrations rather than everyone who was invited or clicked interested. Recheck the count before purchasing perishables, and separate children from adults when the menu allows smaller portions.
Frequently asked questions
How much extra food should a reunion buy?
Five to ten percent is often enough for a reliable guest count. Use a larger buffer for open invitations, long serving windows, or events where relatives may arrive without registering.
Does this calculator replace a caterer quote?
No. It provides an early shopping estimate. Caterer portions, recipes, package sizes, and local food-safety requirements should control the final order.
How should children be counted?
The calculator uses smaller portions for children under 12. Teenagers should generally be counted as adults.
