The formula
Attendees × days × F&B per person + every other cost line = cost lines.
Cost lines + contingency = total cost. Total cost ÷ attendees = cost per attendee.
Tickets + booths + sponsorship − total cost = net. (Total cost − booths − sponsorship) ÷ tickets sold = break-even ticket price.

Planning estimate only. The default costs and prices are planning assumptions, not market data: replace them with quotes from your venue, caterer and suppliers and with last year’s actuals.
Event Budget by Line Item
Each cost line, what it costs per attendee and its share of the total, contingency included. The largest shares are where a better quote saves the most.
| Cost line | Cost | Per attendee | Share |
|---|---|---|---|
| Venue rental | $20,000 | $25 | 13.3% |
| Food and beverage800 attendees × 2 days at $40 | $64,000 | $80 | 42.5% |
| AV and production | $15,000 | $19 | 10% |
| Staffing | $12,000 | $15 | 8% |
| Marketing | $10,000 | $13 | 6.6% |
| Decor and rentals | $8,000 | $10 | 5.3% |
| Insurance and permits | $3,000 | $4 | 2% |

How the Event Budget Calculator Works
1. Set attendance and event days
Count everyone you feed and seat, comps and speakers included, and the days the event is open. Food and beverage and cost per attendee are worked out from these.
2. Enter each cost line
Use quotes or last year’s actuals for the venue, AV, staffing, marketing, decor, insurance and technology. Price staff in detail with the event staffing cost calculator and bring the total back here.
3. Keep a contingency
A percentage on top of every line covers overruns and late changes. Keep it as its own line so you can see when you start spending it.
4. Add ticket, booth and sponsorship revenue
Enter paid tickets and the price you receive, the booths you expect to sell and your sponsorship total. To see how many booths cover a given budget, use the trade show break-even calculator.
5. Read the net and the break-even ticket price
Check the net result, see which line takes the largest share, and compare your cost per head with the cost per attendee calculator. Then set the final price, fees and comps included, with the event ticket price calculator.

Where an Event Budget Goes, and How to Close the Gap
Food and beverage, the venue and production are usually the largest costs; booths and sponsorship are the revenue organizers can grow fastest. These are the levers, and what each one trades away.
| Budget driver | What you can change | Watch out for |
|---|---|---|
| Food and beverage | Cut a catered meal for a coffee break, use a buffet instead of plated service, or let a sponsor host a reception. | Venue food and beverage minimums: falling short can cost you the difference anyway. |
| Venue | Ask about off-peak dates, a shorter hold or a smaller hall that fits the floor plan you actually sell. | Load-in and teardown days are usually charged too. |
| AV and production | Use the venue's in-house AV for small rooms and bring in a production company only for the main stage. | In-house AV can carry a patch fee if you bring your own supplier. |
| Booth revenue | Sell more of the floor: premium pricing for corners and aisle-end booths, early-bird deadlines, a waitlist. | Each extra booth adds furniture, electrical and exhibitor services you may have to cover. |
| Sponsorship | Package what you already pay for (lanyards, the Wi-Fi, a coffee break, the app) as named sponsorships. | Every package is a promise you must deliver and report on. |
Exhibiting Rather Than Organizing?
This calculator budgets the whole event from the organizer’s side. If you are budgeting a booth at someone else’s show, with space, booth build, shipping and travel, use the trade show budget guide instead.
Grow the Revenue Side With Map D
Map D doesn’t keep your event budget; use this calculator and a spreadsheet for that. It handles the revenue side for expos and trade shows: with booth sales software exhibitors pick and pay for booths on an interactive floor plan, and sponsorship management software sells your packages, with invoices, orders and sales reporting in one place. Running the whole show? See expo management software. Registration and ticketing are a quoted add-on. You can build one event’s floor plan free; publishing it and selling booths needs a paid plan, from $1,500 per event.
What this assumes
Every figure the calculator starts with, and where it comes from. Where the honest answer is that a number depends on your venue, it says so rather than inventing one.
- Attendees and event days
- Everyone you feed and seat: paid attendees, comps, speakers, volunteers and any exhibitor staff you cater for. Food and beverage and cost per attendee use this number. The default is 800 over 2 event days.
- Lump-sum cost lines
- The venue ($20,000), AV and production ($15,000), staffing ($12,000), marketing ($10,000), decor and rentals ($8,000), insurance and permits ($3,000) and technology ($5,000) are totals for the whole event. They are this calculator's example figures, not market rates; replace each with a quote or last year's actual.
- Food and beverage
- $40 per attendee per event day covers a working lunch, coffee breaks and water. Receptions, dinners, venue service charges and tax can double it; use your caterer's per-head quote with service charge and tax included.
- Contingency
- 10% on top of every cost line for overruns, late changes and things nobody priced. Raise it to 15% or more for a first-year event, a new venue or an outdoor event exposed to weather.
- Ticket revenue
- Paid tickets only (700 at $199 by default); leave comps out. The calculator uses the price you receive, so take ticketing fees off the price if you absorb them. Use 0 tickets for a free event.
- Booth and sponsorship revenue
- 30 booths at an average of $2,000 and $25,000 of sponsorship are example figures. Use booths you expect to sell, not the number on the floor plan, and sponsorship you have signed or can reasonably close.
- Break-even ticket price
- Total cost less booth and sponsorship revenue, divided by paid tickets. It is the lowest average ticket price that covers the budget at the attendance you entered, before ticketing fees.
What it does not model
- Ticketing and payment processing fees, comps and a target surplus. The event ticket price calculator handles all three when you set the final price.
- Sales tax, VAT and venue service charges, unless you include them in each line.
- Cash flow: when deposits fall due and when ticket, booth and sponsor money arrives. Plan it, and track actuals as invoices arrive, in the event budget template.
- Speaker fees, travel and hotels, prizes and gifts, and exhibitor services such as freight and electrical that you resell. Add them to the closest line or to the venue or decor line.
- Attendance risk. The result assumes the ticket and booth sales you enter; run it again at a lower number to see the downside.

Frequently asked questions
How do you calculate an event budget?
List every cost line for the event (venue, food and beverage, AV and production, staffing, marketing, decor and rentals, insurance and permits, technology), price food and beverage per attendee per day, and add a contingency of around 10%. Then list revenue: paid tickets times the ticket price, booths sold times the booth price, and sponsorship. Revenue minus total cost is your net; total cost divided by attendees is your cost per attendee.
How much does it cost to put on an event?
It depends on attendance, days, the venue and the catering more than anything else, so build it from quotes rather than a national figure. At this calculator's defaults (800 attendees over 2 days) the total is $150,700, or $188 per attendee, with food and beverage the largest line at 42.5%. Those figures are planning assumptions, not market data.
How much contingency should an event budget have?
Around 10% of the cost lines is a common planning assumption for a repeat event at a known venue. Use 15% or more for a first-year event, a new venue or an outdoor event, and keep it as a separate line rather than padding each estimate, so you can see when you start spending it.
How do I work out the break-even ticket price?
Subtract booth and sponsorship revenue from the total cost, then divide what is left by the number of paid tickets you expect to sell. At this calculator's defaults, $150,700 less $85,000 of booth and sponsor revenue leaves $65,700 across 700 tickets: $93.86 a ticket. Add ticketing fees and any surplus you want on top of that with the event ticket price calculator.
Can Map D help with an event budget?
Map D doesn't keep your event budget; use this calculator and a spreadsheet for that. It handles the revenue side for expos and trade shows: sell booths online with checkout on an interactive floor plan, sell sponsorships, issue invoices and track orders, and report on sales. Registration and ticketing are a quoted add-on. You can build one event's floor plan free; publishing it and selling booths needs a paid plan from $1,500 per event.
