Q

How many guests should I invite to a birthday party?

A common guideline is to invite the number of guests equal to the child's age plus one. For a 5-year-old, that is about 6 guests. Average kids parties have 10-15 guests. Smaller parties (6-8) are easier to manage and more cost-effective, typically saving $100-$200.

  • Rule of thumb: Child's age + 1 guests
  • Toddler party (2-3): 4-6 guests with parents
  • Preschool (4-5): 6-8 guests
  • School age (6-10): 8-15 guests
  • Tweens (11-13): 6-10 close friends
  • Expect 70-80% attendance rate from invitations
Q

What are the most affordable birthday party ideas?

The most affordable parties are at home or in parks ($0-$75 venue). Serve pizza ($3/guest), make a homemade cake ($10-$20), use dollar store decorations ($15-$25), and plan free activities like scavenger hunts or relay races. Total cost: $100-$200 for 12 guests.

  • Home or park venue: $0-$75
  • Homemade cake: $10-$20 (vs $40-$80 bakery)
  • Dollar store decorations: $15-$25
  • DIY goodie bags: $2-$3/guest
  • Free games: Scavenger hunt, relay races, freeze dance
  • Total budget party: $100-$200 for 12 guests
Q

How much should I spend on party favors?

Party favors typically cost $3-$8 per guest. Simple goodie bags run $2-$4 each, themed favors $5-$8, and experience favors like small craft kits $6-$10. Many parents now skip traditional favors and instead donate to charity or send guests home with leftover cake.

  • Simple goodie bag: $2-$4/guest
  • Themed favors: $5-$8/guest
  • Craft/activity kits: $6-$10/guest
  • No-favor trend: Donate to charity instead
  • Edible favors: $3-$5/guest (cookie decorating, candy bags)
