[Debconf-team] A better budget analysis

[Richard Darst <rkd@zgib.net>]

Hi,

This email is from darst (who takes responsibility for most editorial
opinions) and hug, about budget things.

Le Camp:
- ~ 95 kCHF fixed costs, which about matches a "safe" initial
  sponsorship estimate.
  (65 kCHF all accom and 30 kCHF other)
- This is with no attendees.  Each additional attendee costs ~225/week
  (due to food only).
  - Each extra professional registrant, (600 CHF/week), allows 2.6
    attendees to come [so 1.6 sponsored attendees]
    - But these 1.6 sponsored attendee-weeks must also cover DebCamp
      people
  - Each extra bronze sponsor allows 9 attendees to come, gold, 50 to
    come.
- This is with NO travel sponsorship at all.
  - Each 10 kCHF travel sponsorship costs 45 attendee-weeks
- There seems very little potential for reducing overhead costs (70
- kCHF lecamp) or per-person (34 CHF/person-day food)
- If we get to more than 400 person-weeks, per-person costs go up,
- since we must pay more accom. (324 beds total, it is unlikely we'll
- get to this much without > 100 at DebCamp).


Interlaken:
- ~50 kCHF of overhead costs (20 kCHF venue + 30 kCHF other)
- Each attendee costs about 350/week (since we must pay per-attendee
accom)
- The savings of overhead allow about 140 attendees to attend.
- Each 600 CHF prof attendees allow 1.7 attendees to come. [so .7
  sponsored attendees]
- Each sponsor...
  - Each bronze sponsor allows 5.7 attendees to come
  - Each gold sponsor allows 34 attendees to come
- This is also with NO travel sponsorship at all.
  - Each 10 kCHF travel sponsorship costs 30 attendee-weeks.
- Due to all the options and time before commitment, there is a lot of
- potential to reduce the costs.

Common to both:
- We assume 100 kCHF income.  This is still quite a lot more than past
  years, but not totally fanciful.
- All "person-week" things above include DebCamp.  So if we can afford
  150 person-weeks, that could mean 50 DebCamp and 100 DebConf only.
- **NO* travel sponsorship included*!  This means this DebConf will
  exclude many people who can't afford to come.  I think this is a
  problem for both of these options so far...


Comparison:
- Le Camp and Interlaken cost the same for 360 attendee-weeks.  Below
  this, interlaken is cheaper, above this, lecamp is cheaper
  - Above 400 person-weeks, we have to pay per-person accom at le
    camp, so it becomes more expensive.
- According to these calcs, we need 133 professionals (at 600
  CHF/week) to achieve 360 person-weeks at le camp (or lots of extra
  sponsorship).  So given our likely situation, le camp remains more
  expensive.


Notes:
- Interlaken 350/week = CHF25 accomodation (including breakfast) +
  CHF25 food (lunch+dinner) / day
  - if we lower to food budget to CHF 20? CHF315/week
- Le Camp 225/week includes only food, since most accom would be below
  forfait (minimum cost).


Thanks,

- Richard (and hug)
