Wedding Catering Cost Calculator NZ

This calculator estimates the cost of catering a wedding, both per guest and as a total, so you can budget the reception with confidence. Catering is usually the single largest line in a wedding budget, and it scales directly with the guest list, which is why the per-head figure is the number couples and venues talk about most. But the true cost is not just food per person: there is drink, whether a bar tab or per-head package, and a set of fixed costs that do not change much with numbers, such as staff and waiting, equipment and marquee hire, and extras like the cake, a celebrant's meal or late-night snacks. Bringing these together gives both the all-in cost per guest and the grand total, which is what you actually need to budget. This tool does it. You enter the number of guests, the food cost per head, the drinks cost per head, and your fixed costs split into staff and hire, and other extras. The calculator returns the total catering cost, the effective all-in cost per head once the fixed costs are spread across the guests, and the breakdown between variable and fixed spending. The results update as you type, so you can see how trimming the guest list or choosing a simpler menu changes the total. Use it to set a catering budget, to compare quotes from caterers and venues, or to decide where to save. A useful insight the calculator reveals: because fixed costs are shared among all guests, the cost per head falls as the guest list grows, but the total of course rises, so the two pull in opposite directions when you are deciding on numbers.

Total = (food + drinks) x guests + fixed costs. All-in per head = total / guests. Fixed costs are shared across guests, so the per-head figure falls as numbers grow.

How it works

The variable cost is the food plus drinks per head, multiplied by the number of guests. The fixed costs, staff and hire plus extras, are added to that to give the total catering cost. Dividing the total by the number of guests gives the all-in cost per head, which spreads the fixed costs across everyone.

Worked example

For 100 guests at $75 a head for food and $35 for drinks, the variable cost is $110 times 100, which is $11,000. Adding $2,500 of staff and hire and $800 of extras, $3,300 of fixed costs, gives a total of $14,300. Spread across 100 guests, that is an all-in cost of $143 per head.

Frequently asked questions

How much does wedding catering cost per head in New Zealand?

It varies widely with the style of reception, from a casual buffet to a plated multi-course dinner with a full bar. This calculator builds your own per-head figure from your food and drink choices plus fixed costs, which is more useful than a generic average.

Why does the per-head cost change with guest numbers?

Because fixed costs like staff, hire and the cake are shared across all guests. With more guests those fixed costs are spread thinner, lowering the cost per head, even though the total rises. Fewer guests means each one carries more of the fixed cost.

What should I include in catering costs?

Food and drink per guest are the main variable costs. Add fixed costs such as waiting and bar staff, equipment, crockery or marquee hire, and extras like the cake, late-night food and meals for vendors. Including these gives a realistic total rather than just the menu price.
