"How much does a wedding cost?" The average answer is everywhere, and it barely helps: your wedding isn't average. What is useful is understanding which lever actually moves the total. And that lever is neither the photographer nor the flowers.
The headline figure, and what it hides
The 2026 report on the French wedding industry, compiled by Mariages.net from 1,304 couples married in 2025, gives two numbers:
| Indicator | Published amount |
|---|---|
| Average wedding budget | €19,293 |
| Average cost per guest | €215 |
Put the two together and you get an average wedding of about 90 people. In other words: the average budget doesn't describe your wedding, it describes a wedding size. For 100 guests, the same study leads mechanically to roughly €21,500, a simple multiplication of the cost per head.
The breakdown, item by item
These amounts come from the Mariages.net white paper, whose cited edition dates from 2023: treat them as orders of magnitude, not as quotes.
| Item | Average amount |
|---|---|
| Venue and catering | €110 per guest |
| Honeymoon | €4,550 |
| Wedding dress | €1,650 |
| Photographer | €1,300 |
| Music | €1,200 |
| Videographer | €1,200 |
| Groom's suit | €1,100 |
| Engagement ring | €1,100 |
| Flowers and decoration | €950 |
| Invitations and stationery | €425 |
| Hair and make-up | €200 |
What changes everything: the number of guests
Look at the first line. €110 per guest for the venue and the caterer, a little over half the cost per head. That line is the only one that multiplies without limit.
Ten more guests isn't a bit more cake: it's about €1,100 more on the reception item alone, before you even count the extra invitations, the beds and the guest favours. Conversely, trimming ten people frees up the same sum, enough to pay for the videographer you were hesitating over.
This is why knowing precisely who is coming is a financial matter, not merely an organisational one. A caterer invoices on a declared number. Declaring 110 covers "just in case" when 92 people turn up means paying for 18 meals nobody will eat, close to €2,000.
The item where the saving is easiest to take
The €425 of stationery deserves a pause, because it is the only item on this list you can divide without taking anything away from the day.
A quality printed invitation for 60 households, lined envelopes, addressing and postage included, comes to €456 to €966 once everything is added up, reply cards included. A complete digital invitation costs €49 for the event pass with Invitez-nous, with 12 months of hosting, RSVP and a gift fund at 0 % commission. We broke this calculation down item by item in our paper versus digital comparison.
The real gain isn't there, though. It's in the response rate: a good share of paper reply slips never come back, which leaves you guessing at the number of covers. An online RSVP with automatic reminders gives you the exact figure before you pass it to the caterer.
And what about the gift fund?
The honeymoon weighs €4,550 on average, often funded by the gift fund. Watch what the platforms take out of it: from 1 to 6% depending on the provider, which is up to €273 on that line alone. Our comparison of gift fund fees puts a figure on the gap, and the calculator does it on your own amount.
In short
Three things to remember. The average budget doesn't concern you, the cost per guest does. That cost is dominated by the venue and the caterer, and therefore by the length of your list. And two items shrink without sacrificing anything: stationery, and the commissions you shouldn't be paying on money people are giving you.
