Birthday parties in Hong Kong can be very expensive! A standard 15-guest kids’ birthday party in Hong Kong usually costs HK$5,000 to HK$12,000 once venue, food, cake, decorations, and goodie bags are counted. That range surprises parents who only priced the cake.
In a city of small flats and booked-out Saturdays, the useful decision is which line items make the afternoon feel special.
Set the guest list before invites go out, then shortlist rooms in our 50 unique kids party venues in Hong Kong guide.
Most Hong Kong kids parties run 90-120 minutes, not a full afternoon. Caterers who handle local birthdays describe a steady pattern: 15-25 children, with 8-15 adults staying for the first hour. Pizza is the default plate. Cake lands around the three-quarter mark. Goodie bags go out at the door.
The Scoop: Hong Kong Kids Birthday Party Costs:
General Items For Budgeting:

| Food | HK$2,000–2,500 25–30% of budget | Self-catered or delivery. About HK$67–83 per guest. Hotel catering is much higher, at HK$80–200 per head. |

| Favours / goodie bags | HK$300–600 5–10% of budget | About HK$10–30 per child on this budget. Bought bags are often HK$30–100 each, so HK$450–1,500 for 15 kids. Find ideas in our party bags and favours guide. |
| Buffer | ~HK$800 ~10% of budget | Overtime, an extra family, or cleaning. Some rooms charge about HK$2,000 per extra hour. |
More Party Items For Budgeting:
| Item | Estimated cost | Extra notes |
|---|---|---|
| Backdrop / cake-table styling | HK$1,000–3,000 | Only if the venue does not include it, some full styling jobs run HK$2,000–5,000. Shop our party decorations and supplies guide, or hand it all to one of the best party planners in Hong Kong. |
| Photography | HK$1,500–3,000 | Many families skip this and use a photo corner plus phones. |
| Hotel function room (instead of a party room) | HK$6,000–10,500 | HK$200–350 per head, food usually included. Easily uses the whole budget before cake and favours. |
| Indoor playground session | HK$150–250 per child | Good for burning energy. Less private, with limited decor. |
| Weekday party room, all-in | HK$5,500–6,500 | About 30% under a weekend room or a typical hotel package. Weekend all-in is often HK$7,500–8,500. |
