The Birthday Party Budget: How We Keep It Under $100

The Birthday Party Budget: How We Keep It Under $100

Kids' birthday parties have quietly become a $400 event. Venue rental, an entertainer, themed decorations, a bakery cake, gift bags for every guest. We did two of those and then stopped, on the day our daughter told us her favorite party ever had been the one in the backyard with a sprinkler. That party had cost about $60. The next three have all come in under $100, and nobody has noticed the budget except us.

Where the money goes in a typical party

ItemTypical costOur version
Venue$150–300Backyard or public park: $0
Entertainer or activity$100–200One game the kid chooses: $0–10
Cake$40–80Homemade: $8
Food$60–100Sandwiches, fruit, popcorn: $35
Decorations$30–60Balloons and one tablecloth: $12
Gift bags$40–80One group activity instead: $15
Invitations$15–25A text message: $0

The rules

  • The kid picks the theme, and the theme is a color and an activity. "Blue and water balloons" is a theme. It does not need licensed plates.
  • Guests equal the child's age, roughly. Six guests for a six-year-old. Twelve was the most we have hosted, and it was fine, but it was the limit.
  • One activity instead of gift bags. Decorating cupcakes, painting rocks, a treasure hunt. Everyone leaves with the thing they made. Nobody misses the bag of plastic.
  • Food that is not pizza. Pizza for twelve kids and eight parents is $90. A tray of sandwiches, a watermelon, a bowl of popcorn and juice boxes is $35, and the kids eat the same amount either way, which is not much.
  • The parents stay. This turns a children's party into a neighborhood afternoon, and it means there are twelve adults watching the sprinkler instead of two.

The last one, itemized

Twelve children in the backyard on a Saturday afternoon in June. A homemade chocolate cake ($8 in ingredients). Sandwiches, fruit, popcorn, juice ($34). Balloons, one tablecloth, streamers ($11). Water balloons and a bag of rocks and paint for the activity ($16). Paper plates and cups we already had. Total: $78.

The parents stayed, the kids ran around for three hours, and the only thing anyone asked for afterward was the sprinkler again.

What we do not skimp on

The cake is homemade but it is a real cake, decorated with the child, and it is the center of the afternoon. The photos get printed and one goes in a frame. Those are the two things the children remember, and neither of them costs much.

Three parties, three budgets

Seventh birthday, backyard12Cupcake decorating and rock painting$78

What the children said afterward

We asked, because we were curious whether they noticed the difference from the venue parties. The nine-year-old said the treasure hunt was "the best one" because she had helped draw the map. The younger one wanted the sprinkler again and could not remember the trampoline park at all. That is not proof of anything, but it matched what we suspected: the parts of a party a child remembers are the parts they were part of, and those are the cheap parts.

If the budget is tighter than $100

A park, a homemade cake, a bag of balloons and a game. Skip the food beyond cake and fruit by holding the party at three in the afternoon, between meals. That version is about $30, and nobody under ten will notice.
