Birthday Party Budget
Plan a birthday party budget from guests, venue and food costs.
About Birthday Party Budget
Per-guest costs scale with the guest list, while fixed costs like the venue, cake and decorations stay the same regardless of headcount. Splitting the total by guest or by hour shows where the money goes. Kids' parties have a habit of growing, so agreeing on a fixed cap per guest and per venue keeps the celebration affordable.
