How much does adding one more wedding guest cost?
The marginal cost of one extra guest is different from average cost per guest. Use the expenses that actually rise with headcount, then check whether your venue has a capacity tier that creates an additional fixed cost.
Methodology
| Component | Tool assumption |
|---|---|
| One guest | Catering + bar + rental/decor + favor + optional threshold |
| Five guests | Guest costs × 5 + optional threshold |
| Venue threshold | $500 when selected |
Examples
Budget catering
$50 food + $15 bar + $5 rentals + $0 favor = $70 per guest before a venue threshold.
Mid-range catering
$80 food + $30 bar + $10 rentals + $5 favor = $125 per guest before a venue threshold.
Premium catering
$150 food + $60 bar + $20 rentals + $15 favor = $245 per guest before a venue threshold.
Common mistakes
- Using the entire wedding average cost as marginal guest cost.
- Forgetting capacity tiers.
- Leaving out per-person drinks or rentals.
