Pro Tip

The 50/30/20 rule for party budgets: 50% on food + venue (the essentials), 30% on activities + entertainment (the fun), 20% on decorations + favors (the extras). If you're over budget, cut from the 20% first — decorations are the first thing parents over-spend on and the last thing kids remember.

Frequently Asked Questions

How do I plan a birthday party on a $200 budget?

On a $200 budget, allocate 30% to food ($60), 15% to decorations ($30), 15% to entertainment ($30), 10% to cake ($20), 10% to supplies ($20), and split the remaining 20% between favors, invitations, and photography. Focus on DIY decorations, homemade food, free games, and digital invitations to maximize every dollar.

How should I budget for a kids birthday party?

Start with your total budget and allocate by priority: food and drinks should get 25-35% since it is the biggest expense, decorations and entertainment each get 10-15%, cake gets 8-12%, supplies get 8-10%, and favors, invitations, and photography split the rest. Mark categories as must-have, nice-to-have, or skip to optimize your spending.

What are cheap birthday party ideas for kids?

Host at home instead of a venue to save $100-300. Use DIY decorations from dollar stores, make your own food (pizza bagels, fruit skewers, popcorn), play free games like musical chairs and scavenger hunts, use digital invitations, and skip goodie bags in favor of a single take-home craft. A memorable party does not require a big budget.

How much does an average kids birthday party cost?

The average kids birthday party costs $300-500 for a home party with 10-15 guests. Venue parties range from $200-800+ depending on the location. The biggest expenses are food (25-35%), entertainment (15-20%), and decorations (10-15%). You can throw a great party for under $200 with smart budgeting and DIY strategies.

Should I splurge or save on birthday party decorations?

Save on decorations. Dollar store balloons, printable banners, and one statement piece like a DIY balloon arch create just as much impact as expensive themed sets. Invest the savings into food, cake, or entertainment instead — kids remember the fun and the food more than the tablecloths.

What is the best way to save money on a birthday party?

The top money-saving strategies are: host at home instead of renting a venue, use digital invitations instead of printed ones, buy solid-color supplies from dollar stores, make DIY decorations, order food in bulk from warehouse stores, bake your own cake or buy a grocery store sheet cake, plan free games and activities, and skip traditional goodie bags.
