🎉 Party Budget Calculator

A casual home party costs $15–40 per person. A restaurant or hired venue party runs $50–100 per person. A catered event with open bar can cost $100–200+ per person. Kids' birthday parties typically run $15–30 per child.

Food and beverage combined typically account for 50–65% of party costs. Venue rental is the second largest expense (if applicable), followed by entertainment and decorations.

Host at home to eliminate venue costs, opt for a potluck or semi-catered format, buy alcohol in bulk from warehouse stores, use digital invitations, DIY decorations using Pinterest ideas, and schedule during off-peak times.

Plan for approximately 2 drinks per person in the first hour, then 1 drink per hour afterward. For a 3-hour party, budget for 4–5 drinks per person. A standard 750ml bottle of wine provides 5 glasses; a case of beer provides 24 drinks.

For a casual birthday party, $50–150 covers basic decorations. A themed party or special event might require $200–500+. DIY decorations, balloon arches, and reusable items can significantly reduce this category.
