How to Budget a Corporate Conference: A Full Cost Breakdown
A corporate conference in Korea typically starts at ₩30–50M for a 100-person seminar, ₩80–150M for a 300-person conference, and ₩200M+ for a 1,000-person flagship. But the total matters less than where the money goes. Understand the line-item structure first, and you can design your budget before you ever request a quote.
Split your budget into six line items
Event budgets generally break down along these lines — and your quotes should be itemized this way too, to avoid disputes later.
- Venue rental: 25–35%
- Food & beverage: 20–30%
- Production (stage, sound, lighting, video): 15–25%
- Staffing & operations: 8–12%
- Design & fabrication (booths, signage, branding): 5–15%
- Contingency: ~10%
Venue: the biggest swing factor
Venue cost varies most by type. Five-star hotel ballrooms run roughly ₩10–30M for a full-day rental and usually require in-house F&B. Dedicated convention facilities are typically cheaper than hotels with more flexible vendor rules. Unique venues like museums and cultural spaces may have low rental fees, but they shift cost into production since you bring in staging, sound, and catering.
F&B: scales directly with headcount
Food and beverage rises almost linearly with attendance. Hotel banquet (seated) runs ₩100,000–200,000 per person; buffet or cocktail reception ₩70,000–150,000. Where budgets quietly explode is alcohol — a hosted bar for a 300-person reception can add ₩10–30M depending on the pour, so set your bar policy early.
Production: jumps in steps
Production scales by tier, not headcount.
- Basic (screen, projector, sound, simple lighting): ₩3–10M
- Mid-tier (LED wall, stage design, show lighting, recording): ₩15–50M
- Full production (custom staging, multi-camera, live streaming, show calling): ₩50M and up
A common mistake is booking a beautiful raw venue with no budget left to power it. If you pick a unique venue, assume production at 1.5–2x a hotel event.
Staffing & interpretation
A dedicated PM and on-site crew scale with event size; above 300 guests a show caller is effectively essential. If international guests attend, budget separately for simultaneous interpretation (two interpreters per language, plus booth and equipment) — roughly ₩5–15M for a two-language event.
What moves the number most
- Headcount — F&B and staffing scale directly with it. Be honest about attendance.
- Venue type — the hotel-vs-unique-venue choice moves more money than any other decision.
- Peak weeks — during major event weeks like Korea Blockchain Week (Sep 29 – Oct 1, 2026), venue and vendor rates spike. Book months ahead or pay the premium.
- Production ambition — an LED wall and show lighting transform an event, and the budget with it.
Frequently asked questions
What's a realistic budget for a 100-person seminar?
Around ₩30–50M for a solid event at a good venue with standard AV and lunch. Add an evening reception and bar and it rises quickly.
How much contingency should I hold?
Ten percent of the total. In practice it gets used — on last-minute headcount increases, added interpretation, or weather plans.
Why insist on an itemized quote?
A single lump-sum quote is the seed of later disputes. Only a quote split into venue, F&B, production, staffing, fabrication, and contingency lets you compare and negotiate.
Do venues require deposits?
Yes — typically 30–50% on contract, with the balance before or shortly after the event. Popular venues won't hold dates on a verbal confirmation.
