Establishing a realistic provisional budget is the first step in any event organisation. For a corporate event with 300 people, there are numerous variables: format (day event or residential), destination (Paris, provincial, international), service level, duration, and staging ambitions. Here is a detailed line-by-line estimate, based on French market practices in 2024-2025.
The 3 Reference Service Levels
Before detailing the individual budget lines, let us frame the three service levels commonly observed:
- Standard format: 4-star hotel in the provinces, 1 night, modest programme — €350 to €480 per person — total budget: €105,000 to €144,000
- Semi-premium format: 4 or 5-star hotel, attractive destination, 1 to 2 nights, refined staging — €550 to €800 per person — total budget: €165,000 to €240,000
- Premium format: prestige destination, 2 nights, elaborate stage production, gala dinner — €900 to €1,400 per person — total budget: €270,000 to €420,000

FAQ — 300-Person Event Budget
Can one organise a quality event for 300 people with a budget of €100,000?
Yes, in day format non-residential with a provincial venue. You will have approximately €333 per person, which allows for a quality programme without accommodation. The most impactful line item to reduce is accommodation — not technical or entertainment.
Which line item is most difficult to compress?
Catering and accommodation, as they are directly perceived by participants. Compressing these line items risks disappointment. Stage technical is more compressible if the programme remains modest, but poor sound quality is unforgivable.
How does one obtain comparable quotes for 300 people?
Draft a precise brief (dates, format, number of participants, desired accommodation type, indicative programme) and approach 3 to 5 venues and agencies simultaneously. Use the seminaire.com platform to compare venue offers directly.
