Wedding budget for 100 guests
A wedding budget for 100 guests: balance service and uncertainty.
At roughly 100 guests, catering, rentals, staffing and RSVP movement can change several categories together. Build the model from the contracted count rules, not a round number alone.
Illustrative $30,000 model: $12,000 fixed costs + ($160 × 100 guests) + $2,000 contingency = $30,000. It is an example calculation, not a price promise.
A sample allocation that adds up
This model separates the expenses that scale from those that do not.
| Decision group | Example amount | Control point |
|---|---|---|
| Venue & fixed services | $6,000 | Confirm time, spaces, staffing and required vendors. |
| Photography, attire, music & ceremony | $6,000 | Compare complete packages and overtime. |
| Food, beverage, rentals & stationery | $16,000 | Recalculate after every major RSVP update. |
| Contingency | $2,000 | Hold outside category wish lists. |
| Total | $30,000 | Record committed, paid and still available separately. |
Model three attendance outcomes
Run the per-person categories at 90, 100 and 110 guests. The goal is not to predict the exact RSVP total; it is to know which decisions become uncomfortable at each outcome.
Do not mix estimates and signed commitments
Keep early allowances visibly separate from accepted quotes. Once a contract is signed, record taxes, service charges, payment dates and cancellation terms—not only the deposit.
