Profit sharing and overhead can be somewhat of a moving target. So far, I think the plan is reasonable as I understand it. The bands get a 4 to one split at the door. All of pre-sale tix by the band are kept by them.
Since there isn't a further description of the venue or business model, we'll have to work with some assumptions. Or look at set of scenarios.
Here's one -
400 person venue
6 bands, average 4 per band=24 people.
bands get 30 tix each = 180 tix.
Satellite sales move 110 of the presale balance of 220 tix, rest revert to the door of the venue for sale.
Bands A,B and C sell all of their tix. A,B and C now have $150 @ 5 bucks a ticket eac.
Bands D,E,F sell 1/2 of theirs. totalling 15 tix each- sales of 45 bucks each.
So, let's also assume the D,E,F tix revert to the door if not sold.
So, the door is now Satellite pre-Sales 110 tix x 5 dollar = $550
Lets say the door sells all the tix reverted from D,E, F 45 tix x $6 = 270
Plus all their own, 110 x 6 = 660
Total door is then 1480. Band share is 80% - 1184 total /6 = 197.30
Adding Bands A,B, and C get 347.3 each
E, D and F get 242.30 each.
House gets 20% of door or 296.00 with sound guy, bouncer and stage manager pulling just under a hundred each.
ABC get 86.82 for each guy.
EDF get 60.57 each guy.
And that's pretty much the topside of it. If they sell less, it gets worse.
Lets say the sell 10 tix per band.
Each band gets 50 bucks.
150 tix go back to door
Presales sell only half of theirs, that's 55 x 5 = $275
Now 255 tix are at the door. If only a half sell, at 6, that 765 at the door x .8 =612/6 = 102 per band.
So band sales plus door yields 152 per band/4 = 38.00 dollars each per band guy.
House door is 153 dollars to cover sound bouncer and manager,
That will get old fast, by the time people go in set up, pay the gas money and have a few beers, they are even if they are lucky.
If everything is close to perfect, it's workable. If it's weak, it's awful.
A band would do better risking a fixed contracted door % and same base pay trusting that they were good enough to make money at the door, IMO.
However, the analogy may be invalid, as I can't plug your numbers in for it. You do it and see where you think it works out. Basically the answer is at X amount of money or greater it works. Under X and it doesn't and define what that number is.
