How to Estimate Your Total Budget

Follow this simple formula:

• Step 1: Decide your guest count
• Step 2: Pick your venue type (home, park, venue)
• Step 3: Estimate food cost per person × number of guests
• Step 4: Add entertainment, cake, decorations, and favors
• Step 5: Add a 15% buffer for unexpected costs

Example budget for a 7-year-old's party (15 guests, trampoline park):

• Venue package (15 kids): $350
• Upgraded food: $75
• Custom cake: $60
• Decorations: $40
• Goodie bags ($5 × 15): $75
• Total: ~$600

Quick Tips to Save Money

• Host at home or at a park to eliminate venue fees
• Use digital invitations (Evite, Canva, or Paperless Post)
• Make your own cake or order from a grocery store bakery
• Skip elaborate goodie bags — one fun item per kid is enough
• Choose off-peak times (morning parties, Sundays) for venue discounts
• Combine entertainment and venue (trampoline parks, bowling alleys)
• Ask family members to help with food, setup, and entertainment
