How much does a kids' birthday party cost in 2026?
For most families, a kids' birthday party costs around $300 to $500 for 10 to 15 guests at home. Booking a venue, adding hired entertainment, or going big on decorations can take the total past $800. The two biggest budget lines for a booked-venue party are usually the venue and food. At-home parties spread costs more evenly across food, cake, decorations, and favors.
Here are the typical US ranges the calculator is built on:
- Booked venue: a $99 to $199 base package plus $18 to $40 per child, so the venue line alone for 10 kids lands between $280 and $600 at mid-tier prices, with major metros running higher.
- Food and drinks: $5 to $12 per child. Many venue packages already include pizza and drinks.
- Cake: $30 to $120. A sheet cake feeds about 20.
- 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.
Prices vary by location. Major metros like New York, Los Angeles, and Chicago tend to run about 25% above the national average, while many smaller towns and suburbs run roughly 20% below it. Whatever the total, add about 10% on top for tax, tips, and the little extras that always show up.

Birthday party cost FAQ
How much does a kids' birthday party cost?
Most US kids' birthday parties run about $300 to $500 for 10 to 15 guests at home. Booking a venue, hiring entertainment, or adding custom touches can push the total past $800. For booked-venue parties, the venue and food are usually the two largest budget lines; at-home parties have a more even cost mix.
How much is a birthday party per child at a venue?
Booked venues like trampoline parks, play centers, and bowling alleys typically run a base package fee of $99 to $199 plus $18 to $40 per child. That puts the venue line alone for 10 kids between $280 and $600 at mid-tier prices. With the calculator's default food, cake, decorations, and favors, the full party estimate is $400 to $1,090. Major metros run higher.
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?
Plan on about $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. Printed invitations run $20 to $50, 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?
Entertainment like a bounce house rental, face painter, or balloon artist typically runs $150 to $350 for a party. A games-based party at home can skip this cost entirely.
