A sensible home party budget splits roughly 40–50% food and drink, 15–25% décor (with the balloon arch as the centrepiece), 10–15% cake and desserts, 10% activities or entertainment and 5–10% favours and extras. Food scales with guests; décor mostly doesn’t — one 10 ft arch serves 10 guests or 50. Spend on the backdrop and food; save on themed disposables.
Quick takeaways
- Food scales with guests; décor mostly doesn’t.
- The arch is the best-value décor per photo.
- Themed paper goods are the easiest place to save.
- Set the budget before the guest list grows.

Why décor doesn’t scale (and why that’s good)
A 10 ft balloon arch ($129) looks the same whether 10 or 50 people are at the party. That makes décor a fixed cost — a big chunk of a 10-person budget, a small slice of a 100-person one. It’s also why the arch is such good value: it’s in nearly every photo, it replaces dozens of smaller decorations, and it doesn’t get more expensive as the guest list grows.
Sample budgets

| Guests | Food & drink | Décor | Cake | Activities | Extras |
|---|---|---|---|---|---|
| 10 | Pizza + drinks | 5–10 ft arch | Bakery cake | One craft | Small favours |
| 25 | Taco bar or buffet | 10 ft arch | Tiered or sheet cake | Games | Favours |
| 50 | Catered trays | 10–20 ft arch | Large cake or cupcake tower | Music / entertainer | Favours |
| 100 | Caterer | 20–40 ft arch | Cake + dessert table | DJ or band | Signage, rentals |
Where to save
- Themed plates, cups and napkins — plain ones in one arch colour look better.
- Many small decorations — one arch does the job.
- Elaborate favours — kids remember the party, not the bag.
- Rentals you don’t need — use what you have.
- Rush shipping — order early (standard shipping is free).
Where to splurge
- The backdrop — it’s in every photo.
- Food quality — guests remember good food.
- The cake — the second most-photographed thing.
- Lighting — candles and fairy lights transform a room cheaply.
Stylist tipIf you have to choose, size the arch right before adding the Lux upgrade.
Hidden costs to plan for
Set aside about 10% of the total for these — they always show up.
- Ice — always more than you think, especially in summer.
- Serving utensils, trays and foil.
- Trash bags and cleaning supplies.
- A pump and removable hooks for the arch (if you don’t own them).
- Last-minute extras: candles, batteries, tape.
