How much does a wedding cost per guest?
Your guest count drives your budget more than any other decision. Here's what each guest really costs, and how to work out the number for your own wedding.
In the US, the average wedding cost $34,200 for 117 guests, which works out to about $292 per guest (The Knot 2026 Real Weddings Study, couples married in 2025). In the UK, the average was £21,990, about £272 per guest (Hitched, January 2026).
Why the per-guest number matters
Some wedding costs grow with every person you invite: their meal, their drinks, their chair, their invitation, their slice of cake. Others stay the same whether you invite 40 people or 240: your photographer, your outfits, your rings, your music.
That's why a smaller guest list saves more than people expect. In The Knot's data, catering alone averaged $80 per person, before drinks, service charges or the venue itself.
Work out your own cost per guest
Split your costs into two groups, then use this formula:
Fixed costs are the things you'd pay for anyway: photographer, attire and beauty, rings, music, officiant, most of the décor. Per-guest costs are food, drinks, rentals, stationery and favours. Ask your venue and caterer for a price per head, and add a little for everything else.
An example
Say your fixed costs come to $11,500 and each guest costs about $150 in food, drinks, rentals and stationery.
| Guests | Total | Cost per guest |
|---|---|---|
| 60 | $20,500 | $342 |
| 80 | $23,500 | $294 |
| 100 | $26,500 | $265 |
| 150 | $34,000 | $227 |
Two things stand out. First, every 20 guests you cut saves $3,000 here, more than most couples spend on flowers. Second, the cost per guest falls as the list grows, because the fixed costs are shared across more people. So don't judge a quote only by its per-head price; look at the total.

How to bring your cost per guest down
- Make an A list and a B list. Send B-list invitations as A-list declines come in, so you fill the room without over-inviting.
- Choose a Friday, Sunday or off-season date. Many venues charge less per head outside peak Saturdays.
- Change the meal style. A buffet or family-style meal can cost less than a plated three-course dinner, depending on your caterer.
- Limit the bar. Beer, wine and one signature cocktail costs far less than a full open bar.
- Pick a venue that fits. A room sized for 150 makes 90 guests look sparse, and you may pay a minimum spend for the empty space.
Keep track as quotes come in
Per-guest prices change as you go: menus get upgraded, service charges appear, the guest list moves. Update your numbers every time a quote changes, so a small extra per head doesn't quietly add thousands to your total.
