Conference Budget Calculator
Total budget from attendees, venue, AV, F&B, and travel.
About this calculator
This calculator assembles a conference budget line by line, pricing venue, catering, AV, staffing, and every other cost driver independently and summing them before applying a contingency buffer. Venue and catering scale by event length (daily rate times days, and a per-person daily catering rate times attendees times days), while AV is a flat daily production budget also multiplied by the number of days. Materials — badges, lanyards, programs, signage — step down per person as your event gets larger ($25/person under 200 attendees, $18 up to 500, $12 above that), reflecting real economies of scale in print runs. Staffing follows similar logic: the model assumes one coordinator or temp staffer per 75 attendees (minimum two) at $350/day each, so a 750-person, three-day conference needs 10 staff across all three days.
Insurance and permits step up in three tiers by attendee count ($400/$800/$1,500) rather than scaling continuously, since liability coverage is typically bought in bands, not per head. Travel subsidy is optional and proportional — set it to 0% if attendees cover their own travel, or dial in the percentage of average travel cost your organization reimburses. After summing venue, catering, AV, speakers, travel subsidy, materials, staff, insurance, and a flat $15/attendee marketing line, the calculator layers on your chosen contingency percentage (industry standard is 10-15%) to reach the grand total, then reports cost per attendee and per attendee per day for benchmarking against past events. The venue-plus-catering share of the subtotal is also broken out, since that combined line typically runs 50-70% of a conference budget and is usually the first place to look for savings.

Frequently Asked Questions
Why do materials costs go down per person as the event gets larger?
The calculator uses three per-person material rates — $25 under 200 attendees, $18 up to 500, and $12 above that — because badges, lanyards, programs, and signage are typically ordered in bulk print runs, and larger orders get meaningfully cheaper per-unit pricing from vendors. It jumps between tiers instead of climbing smoothly because print vendor quotes themselves usually come in discrete volume tiers.
How does the calculator determine the number of event staff needed?
It assumes one coordinator or temporary staffer per 75 attendees, with a floor of two staff regardless of how small the event is, each billed at $350/day. A 750-attendee, three-day conference needs ceil(750/75) = 10 staff, and that daily staff cost is then multiplied by all three event days.
Why does insurance jump in three price steps instead of scaling smoothly with attendee count?
Insurance and permit costs are modeled as three flat tiers — $400 up to 200 attendees, $800 up to 500, and $1,500 above that — because liability coverage for an event is typically underwritten and quoted in discrete bands tied to expected occupancy, not priced per individual attendee the way catering or materials are.
What does the F&B plus venue percentage output tell me?
It divides your combined venue rental and catering cost by the pre-contingency subtotal, showing what share of your core spend goes to food and space before staff, materials, and other line items. That combined line typically runs 50-70% of a conference budget in practice, so an unusually high or low figure is often the fastest place to check for over- or under-budgeting.
