The total is 6,000 for the venue plus 4,000 of extras plus 100 × 120 for the guests, which is 22,000. Look at where it sits and one line dominates: the guest count contributes 12,000, nearly fifty-five per cent, and it is the only figure in the budget that multiplies. Taking twenty names off the list saves 2,400 and changes nothing anyone can see in a photograph; taking 2,400 off the venue means a visibly cheaper room. Couples who feel the budget slipping almost always reach for the venue, the flowers or the dress — the fixed lines, where every cut is felt — while the multiplying line stays untouched because inviting one more person never feels like spending 120.
A venue of 6,000, extras of 4,000 and 100 guests at 120 each totals 22,000 — and 12,000 of that is a single multiplication nobody thinks of as a decision.
The per-guest figure is bigger than the caterer's quote
Most couples set the per-guest number from the food quote alone, and it is the smaller half of what a guest actually costs. Each name also brings a chair, a place setting, a share of the drinks, a portion of cake, a favour, more staff on the ratio the caterer works to, a bigger room requirement and often a printed invitation with postage. Add those up honestly before multiplying, because an understated per-guest figure is the error that scales — being twenty out on one guest is being 2,000 out on a hundred.
The extras line is where the overrun lives
Venue and catering come with contracts and firm numbers; extras are a list of individually small things that arrives one decision at a time — the rings, the suit, alterations, hair, the photographer's album upgrade, transport, the second bouquet, the sign nobody planned. Each is defensible on its own and none is large enough to trigger a discussion, which is exactly why the line ends up over budget more often than any other. Write the list out in full at the start, price every item even roughly, and the total will be higher than the round number you would have guessed — that higher figure is the honest one.
| Line | Amount | What a 2,400 cut looks like |
|---|---|---|
| Guests (100 × 120) | 12,000 | 20 fewer names |
| Venue | 6,000 | a visibly cheaper room |
| Extras | 4,000 | more than half of them gone |

- How much contingency should the budget hold?
- Ten per cent of the total is the usual planning allowance, and it is not padding — it is the amount that covers a supplier's price rising between quote and invoice, the eight guests who bring a plus-one nobody counted, and the item everyone forgot. On 22,000 that is 2,200 held back and not allocated. If it survives to the day, it becomes a very good bottle; if it is spent by the third month, the budget was never 22,000 in the first place and it is far better to learn that early.
- Does a smaller wedding really cost proportionally less?
- Less in total, but more per head, because the fixed lines do not shrink with the list. Halving this wedding to fifty guests gives 6,000 + 4,000 + 6,000 = 16,000, which is 320 a head against 220 before. That is the right shape: the saving is real and worth having, and the per-head figure rising is simply the venue and the extras being shared among fewer people, not evidence that the smaller wedding was a bad idea.
