How to Build a Party Budget
- Hold back a contingency first. Take 10% off the top and forget it exists — the last week always finds it.
- Split what's left by category. A standard party runs about 40% food, 20% drinks, 20% venue and rentals, 10% decor, 10% entertainment.
- Sanity-check per head. Divide by guests: under ~$15 means self-catered and simple; $50+ means catering is on the table.
- Adjust for style. Cocktail parties shift money from food to drinks; formal events shift it to venue and rentals.
What Parties Actually Cost Per Guest
| Party type | Per guest | 50 guests |
|---|---|---|
| Self-catered backyard | $15–$30 | $750–$1,500 |
| Self-catered + full bar | $30–$45 | $1,500–$2,250 |
| Catered event | $50–$100 | $2,500–$5,000 |
| Formal reception | $150–$300+ | $7,500–$15,000+ |
The Costs People Forget
- Ice, cups, plates, napkins, trash bags — small individually, 10–15% collectively.
- Tips and delivery fees — caterers, bartenders, and rental drivers all expect them.
- Tables, chairs, coolers, extension cords, lighting — borrow before you rent.
- The second grocery run — budget for it, because it always happens.
