How the Kids Birthday Party Budget Calculator works
Total cost = fixed costs (venue, cake, entertainment, decorations) + guests × (food and favors per guest). Per-guest cost = total ÷ guests. Fixed costs stay the same however many children come, while food and favors grow with the guest list, so inviting two more friends usually costs much less per head than the average suggests. Add a 10 percent cushion for surprises. Example: with Number of guests 15, Food and drink per guest 8 $, and Venue cost 150 $, the result is Total party cost = $535; Cost per guest = $35.67; Costs that depend on guest count = $180.
