To find out, Peerspace surveyed 1,000 people who had planned an adult birthday party within the last two years. The results reveal what people are really spending, what pushes costs higher, and where you can save money without cutting the fun.<\/p>\n\n\n\n
Table of contents<\/strong><\/p>\n\n\n\n Quick answer: <\/strong>A realistic birthday party budget often falls between $800 and $1,500<\/strong>, with smaller at-home gatherings on the lower end and larger venue-based celebrations on the higher end.<\/p>\n\n\n\n Our 2025 survey shows a wide range of spending habits, but some clear patterns emerge:<\/p>\n\n\n\n Pro tip:<\/strong> Since the average party had about 24 guests, it\u2019s easy to see how costs for food and drinks rise quickly. Every additional 10 people can add hundreds of dollars in catering or bar expenses, making the guest list one of the most powerful levers in your budget. Explore our guide on who to invite to a birthday party<\/a> if you\u2019re not sure how to trim your list.<\/p>\n\n\n\n When people plan a birthday party, their money doesn\u2019t spread evenly across every detail. Our 2025 survey showed that one category dominated most budgets: food and drinks, and catering.<\/strong> Together, they accounted for the bulk of what people spent, while other categories like entertainment, cake, decorations, and venues played supporting roles.<\/p>\n\n\n\n Takeaway: <\/strong>Food, catering, and drinks dominate as the top spending priority across all demographics. <\/p>\n\n\n\n This category consistently ranks as the #1 budget allocation, with respondents spending the most money here compared to any other party element. However, the data suggests that this category can be challenging to budget correctly.<\/p>\n\n\n\n What the data shows:<\/strong><\/p>\n\n\n\n Pro tip: <\/strong>Because so many people regret both overspending and underspending, this category deserves extra planning and careful budgeting. Use the resources below to lock in the right food and drink numbers.<\/p>\n\n\n\n Takeaway:<\/strong> Entertainment ranks as one of the most important aspects of parties, with 56.2% of respondents citing “fun, entertainment, or activities” as a top priority. <\/p>\n\n\n\n However, spending patterns reveal interesting contradictions. There’s a gap between how important people say entertainment is and how much they actually spend on it, suggesting many party planners could benefit from allocating more budget to this category.<\/p>\n\n\n\n Here\u2019s what the data says:<\/strong><\/p>\n\n\n\n Pro tip: <\/strong>Love having fun at your parties? Bump up your entertainment budget by 5\u201310% more than you think you\u2019ll need. It\u2019s the best way to avoid wishing you\u2019d spent more later.<\/p>\n\n\n\n Takeaway: <\/strong>Cake and desserts are a safe bet\u2014few people regret spending too much or too little here, which shows most planners get the budget just right. Spending patterns suggest they’re often viewed as a necessary rather than a premium expense. <\/p>\n\n\n\n Spending snapshot:<\/strong><\/p>\n\n\n\n Pro tip: <\/strong>Cake is worth the spend! Set aside around 15% of your budget here. Since overspending regret is low and almost everyone includes dessert, adding a little extra for a custom design or upgraded flavors is money well spent.<\/p>\n\n\n\n Takeaway: <\/strong>Venue represents a major binary decision\u2014rent or host at home. When people do rent venues, they’re more likely to regret overspending than underspending, suggesting many could opt for simpler venue solutions without sacrificing party quality.<\/p>\n\n\n\n Spending patterns to know:<\/strong><\/p>\n\n\n\n Pro tip: <\/strong> Consider carefully whether a paid venue makes sense for your party. If managing logistics at a park feels overwhelming or your home isn\u2019t ideal for hosting, renting a space can be worth the investment. Platforms like Peerspace<\/a> offer a middle ground\u2014affordable venues you can rent by the hour with clear, upfront pricing.<\/p>\n\n\n\n Takeaway: <\/strong>Decorations are a \u201cnice-to-have,\u201d and the right budget depends on how much you value aesthetics and creating Instagrammable moments.<\/p>\n\n\n\n How people actually spend:<\/strong><\/p>\n\n\n\n Pro tip:<\/strong> Decide what matters most: your vibe, your feed, or both. Then scale your decoration budget to match. We\u2019ve rounded up some fresh, new party decoration ideas<\/a> if you\u2019re looking for some inspiration.<\/p>\n\n\n\n Takeaway: <\/strong>Party favors are usually the first thing to cut, but the regret numbers show they can still bring meaningful value when you have room in the budget.<\/p>\n\n\n\n Spending patterns to know:<\/strong><\/p>\n\n\n\n Pro tip: <\/strong>On a tight budget? Skip the favors\u2014you likely won\u2019t miss them. Got a little wiggle room and love the details? Go ahead and add them in.<\/p>\n\n\n\n Takeaway: <\/strong>Photography represents a classic “you don’t know what you’re missing until it’s gone” category. While easily cut for budget reasons, the absence is often felt later when memories matter most.<\/p>\n\n\n\n What party planners told us:<\/strong><\/p>\n\n\n\n Pro tip: <\/strong>Love the memories? Don\u2019t skip photos. Low-cost options include asking a friend with a good camera to help in exchange for dinner, or leaving a few disposable cameras on tables for guests to use. <\/p>\n\n\n\n Takeaways:<\/strong> Traditional formal invitations are largely obsolete for modern birthday party planning, making this an obvious area for budget savings without significant regret.<\/p>\n\n\n\n How people actually spend:<\/strong><\/p>\n\n\n\n Pro tip: <\/strong>Skip the paper\u2014digital invites are easier and cheaper. Canva<\/a> and Evite<\/a> are great for setting the vibe, or keep it casual with a quick text that gives guests the key details.<\/p>\n\n\n\n Every party is different, but seeing sample budgets helps you decide what\u2019s realistic for your own celebration.
