Budgeting is a massive part of event planning and often the aspect that causes the most stress for event planners. Budgets rarely go over by accident. Instead planners tend to overspend because of poor planning, underestimating costs and hidden fees that get forgotten.
The budget you see on paper at the start is often just the tip of the iceberg. As planning progresses, you start to see everything that’s below the surface, all the unexpected costs that take you over budget. It’s seldom the large venue bill that cripples the entire event budget, but rather the small fees like corkage or deliveries that move things into the red.
Let’s take a closer look:
One way that event budgets tend to go over is with the simple “yes”:
Yes to the extra appetizer.
Yes to the extra hour of photography.
Yes to the slightly more expensive style of chair.
Event planners are often under pressure to impress their clients and event guests leading to emotional spending. As such, they’re often tempted to say ‘yes’ to small upgrades that might look small at first. The problem is that they don’t consult their budget constantly or update their spreadsheets immediately to keep accurate track of spending.
The “last-minute tax” is another way that event planners go over budget. Procrastination always comes with a cost and when you’re under the pump to deliver on time, the rush delivery fees can really put a dent in your overall budget. Even the most well-prepared event planners can get hit with these last-minute costs if suppliers pull out or can’t deliver on time, forcing event planners to commit extra funds to alternative suppliers with late-fee surcharges.
Another budget surprise comes in the form of underestimating the costs of labor. You can’t forget the people who need to set up and break down your event. Especially if your event runs longer than planned, including setup and breakdown. You may be looking at additional venue fees as well as staff overtime.
All these costs might not seem like much at the time but they can add up fast. Most budget issues come down to one thing: not tracking spend in real time. Your budget is a living document, not a static one. So if you’re not checking it daily, essentially you’re just guessing.
The costs of an event will vary greatly due to a vast range of factors like location, catering style, venue type and size of the guest list, to name just a few. Let’s break down the costs by event size for a better understanding:
Just because an event is smaller, doesn’t always mean it’s cheaper. These events can tend to work out more expensive per person in the end. A lot of suppliers have minimum spend limits that can inflate costs. With fewer guests, event planners also tend to be more detailed and often end up doing more of the heavy-lifting themselves to save costs. Think DIY decor.
Small events can set you back anywhere between $2,000 and $8,000 depending on the setup.
Most small businesses find themselves at this level where there are more moving parts, less opportunity for DIY leading to more sneaky costs. Venue and catering will cost you more and you’ll likely need to add costs for additional staff to help with registration, catering and general coordination. With the larger scale of things, mistakes and last-minute needs can inflate your budget substantially.
Medium events can cost anywhere in the region of $10,000 to $40,000 or more.
Planning large-scale events is essentially like running a mini operation. The biggest costs here come from larger venues, increased catering needs, AV production, staffing and additional marketing. At this level, it’s not the obvious costs that hurt your bottom line, but rather it’s the unexpected ones that wreak havoc.
Depending on the complexity and size, these events can cost from around $50,000 to well over $150,000 depending on how complex of an event you plan.
A common misconception is that event costs don’t scale evenly. Hosting an event for 200 people is not going to simply cost four times what you paid for a 50-person event. You’re entering a different level of complexity whenever you add more people to the guest list.
Most budgets follow a similar pattern. It’s worth following a thoughtful breakdown to prevent spending your entire budget on the venue only to realize you only have $50 left for food.
The space for your event that includes the basics like lighting, tables and chairs.
This includes all food and beverages. Don’t forget to account for taxes and gratuity costs (the “Plus Plus”) that many event planners forget to include.
This includes all your marketing materials and advertising, your registration software (like EventCreate), and any AV equipment you need.
This is generally a value-add for guests, and will only be necessary for certain types of events.
This is your all-important safety net. This part of the budget is there to help you sleep better at night knowing that you can cover the costs when something inevitably goes wrong. For example, a sudden change in the weather and you have to purchase 50 umbrellas on the morning of your event.
No matter how well you plan and prepare your budget, every event planner is bound to forget something in their initial planning. Here are five things that often get left out:
These are service charges and gratuities. Don’t forget to clarify with vendors if their service charges are all-inclusive. Sometimes the service charge only covers administrative costs and not staff gratuities. Clarifying this up-front can save you a $1,000 surprise at the end of your event.
While a lot of venues do offer WiFi connection at no additional cost, some may charge extra for larger events. A basic WiFi setup can fail when 200 or more people are trying to connect at once. Venues may charge extra for better connection speeds and capacity as needed.
Some venues may require event planners to have a general liability insurance policy in place to use their venue. Alternatively, if the venue offers insurance for various risks, it’s at the cost of the event planner and needs to be added to the budget.
If you’re hosting an event in a public space or you plan to serve alcohol at the event, you will need to have the correct permits in place. If you forget to budget for these at the start, they can add an unexpected cost at the last minute.
Sometimes event planners forget that venue hire fees extend past the duration of the event. If your event takes five hours to set up and five hours to break down, you may be liable to pay for additional hours on top of the venue hire fee. Be sure to clarify this with the venue to avoid those pesky overtime charges.
You don’t need a complicated spreadsheet to stay on track, just some thoughtful, strategic planning based on your specific event needs. Here are a few examples:
The goal of a networking event is talking and connection, so there’s no point in focusing on an elaborate stage or seating. Rather invest more in a bar where people don’t need to wait in a 20-minute line for a drink. Try this template:
60% Catering & Bar
20% Venue
10% Music/Vibe
10% Marketing
You’re going to need a tech-heavy setup here. Prioritize things like WiFi and AV equipment. No one is going to talk about the delicious lunch if they couldn’t learn anything because of poor audio quality. Try this template:
40% AV & Tech
20% Materials/Workbooks
30% Catering
10% Speaker Fees
You’re probably looking for something more aesthetic to boost the social shareability of your event. Think “Instagrammable moments”. So you need to budget a bit more for lighting and decor. Try this template:
40% Decor/Branding
30% PR/Photography
20% Catering
10% Contingency
Budgeting problems don’t generally come from mistakes but rather from a lack of visibility of the overall picture. The difference between staying on budget and blowing through it is usually credited to how closely an event planner tracks their budget in real time. This is where the right tools can make a noticeable difference.
Using a platform like EventCreate allows you to keep a closer eye on your event registrations, event details and financials all in one place, rather than spread across multiple spreadsheets, and notes. A successful event planner is able to see how everything is tracking at any given moment and not just after the fact.
Tools like EventCreate make it easier to plan and manage your event budget without adding complexity.” It allows you to focus on key areas that drive the majority of your spend:
Venue and logistics: this often accounts for 30–40% of your total budget once you factor in equipment, setup, and permits
Catering and hospitality: per-person costs can vary significantly depending on the experience you’re creating
Marketing and promotion: directly impacts whether your event reaches the right audience
Staffing and coordination: especially as your event grows in size and complexity
Technology: from registration systems to live streaming for hybrid events
Being able to track each of these areas against your original plan makes it easier to make informed decisions before you overrun your budget and potentially face bigger problems. Comparing your projected costs against your actual spend can give you a level of visibility that helps you stay in control of your budget and analyze numbers post-event.
At the end of the day, staying on budget isn’t about cutting costs, it’s about having a clear view of where your money is going and making adjustments before it’s too late.
The more visibility you have, the fewer surprises you’ll face. And that’s ultimately what keeps an event on track. If you want to simplify that process, tools like EventCreate can help bring everything into one place.
Highly-rated and thousands of reviews worldwide, EventCreate is independently ranked a top event management platform.
