How much does a kids' birthday party cost in 2026?
This calculator uses illustrative planning ranges. With the base estimate and default add-ons, an at-home party for 10 child guests comes to $120–$530; 15 guests gives $155–$625. These are model outputs, not a national average. Confirm local prices and what your venue package includes before booking.
Here are the planning assumptions used by the calculator:
- Booked venue: a $99 to $199 base package plus $18 to $40 per child, so the model’s rounded venue line for 10 kids is $280–$600. Actual packages use different fee structures and may include food.
- Food and drinks: $5 to $12 per child. Many venue packages already include pizza and drinks.
- Cake: $30 to $120. The model budgets one cake per 20 child guests; check serving sizes for your whole group.
- Decorations: $20 to $150 for balloons, a banner, tablecloths, plates, and napkins.
- Goodie bags / favors: $2 to $7 per child.
- Entertainment: $150 to $350 for a bounce house, face painter, or performer (optional).
- Invitations: $20 to $50 if printed, or free with Party Parrot's digital invites.
The lower estimate applies a 0.8 multiplier; the higher estimate applies 1.25. These are optional planning assumptions, not measured local prices. Use quotes from your own area to set your budget.

Birthday party cost FAQ
How much does a kids' birthday party cost?
This calculator uses illustrative planning ranges, not a national average or live quote. At home with the base estimate and default add-ons, it gives $120–$530 for 10 child guests or $155–$625 for 15. Change the options to match your plan, then check actual local prices.
How much is a birthday party per child at a venue?
The model assumes a $99–$199 base fee plus $18–$40 per child. For 10 children, its rounded venue line is $280–$600; with default extras the total is $400–$1,090. Real packages may charge a fixed fee or include food, so use the venue’s current quote and exclude extras already included.
How can I throw a birthday party on a budget?
Host at home or a local park, keep the guest list close to your child's age plus one, serve simple finger foods, lean on a grocery-store cake, and send free digital invitations instead of printed ones. Skipping a booked venue and paid entertainment is where most of the savings come from.
How much should I spend on goodie bags?
The model allows $2 to $7 per child for favors or goodie bags. Stick to a few quality items kids will actually keep rather than a handful of small toys that end up in the trash.
Do I have to pay for invitations?
No. The model allows $20 to $50 for printed invitations, but Party Parrot's digital invitations are free, including RSVP tracking, so you can leave that line out of your budget entirely.
How much does party entertainment add?
The model allows $150 to $350 for paid entertainment. Get a local quote for a rental or performer. A games-based party at home can skip this cost entirely.
