How much does each extra wedding guest cost?

Each extra wedding guest can affect more than the meal. A realistic extra guest cost includes catering, drinks, place settings, stationery, favours, rentals, service charges and a small contingency. The calculator combines those costs so you can estimate the real cost of adding 5, 10, 20 or 30 people.

A-list vs B-list guest cost

If you have an A-list and B-list, use the extra guests field to test the cost of inviting the next group. For example, if your variable cost is £140 per person after service and contingency, adding 20 guests could add around £2,800 to the guest-driven part of the budget.

What guest costs should you include?

  • Food or catering package per person
  • Drinks package, corkage or bar allowance
  • Place settings, chairs, linens and glassware
  • Invitations, menus and postage
  • Favours, welcome gifts or guest extras
  • Service charges, VAT, sales tax or gratuity
  • Contingency for final guest count changes

When removing guests saves the most money

Removing guests saves the most when your venue and catering costs are strongly per-person. It saves less when most of your budget is fixed, such as photography, outfits, ceremony fees and entertainment. For a full average-per-person view, use the Wedding Cost Per Guest Calculator.

Frequently asked questions

How much does adding 10 wedding guests cost?

Multiply your per-guest food, drink, stationery, favour and rental costs by 10, then add tax, service charges and contingency.

Does cutting guests always lower the wedding budget?

Cutting guests usually lowers food, drink and rental costs, but it may not affect fixed costs like photography, outfits, music or ceremony fees.

Should children count in the guest list cost?

Count children if they need food, seating, stationery or favours. If children have a cheaper meal, use an average cost that reflects the quote.

What is the cheapest way to reduce guest-list cost?

Reduce the guest count before cutting every meaningful detail, especially if your catering and drinks are charged per person.
