There's three fair ways to do it.
1.) Everyone gets an even split and pays for all their own expenses. This really tends to be the most common.
2.) Johnson pays all expenses. Even if your group had the sheer natch to get them to agree with this, your take will probably be smaller thanks to this.
3.) Expenses come out of the take and the rest is evenly split.
2 and 3 encourage PCs to be wasteful. Use all the bullets/grenades/etc. that they can. The downside to it is that combat gets pretty crappy when it's just assumed that nades will be thrown off the bat. 3, however, isn't as bad as 2 in that regard. Players can at least talk to each other about throwing all the money away.
I tried a rigger once, and had to have a High lifestyle just to have extra nuyen to be able to replace drones that got destroyed. If I ever try it again, I'm going to try asking the Johnson about getting reimbursed for any drones that get destroyed.
Got to agree with AndyZ for the most part. Everyone gets the same share generally. This is often because a Johnson says "I'll give each of you 10k" instead of "I'll give you guys 50k". Now, there are some expenses that I consider team expenses and that should come out of a 'group fund' or be paid evenly by each member. The biggest of these includes money required for legwork.
The only other thing I would consider team expense would be things that are specifically required of the mission, such as explosives for blowing up a building or a suicide drone that is supposed to act as a diversion (Which does not include a drone that simply gets destroyed during the normal course of a run, or a rigger who decides to use suicide drones as part of his SOP). Medkits would not fall under this, but Medkits would generally fall under a 'Pay back the guy who saved your a$$' (For the same reason that I wouldn't count medical bills for getting injured as part of group expenses)
I believe that including anything more than those things as team expenses unfairly burdens those that are conservative with their resources as they have to cover the expenses of those who are using their resources in a more blase fashion.
Including anything else also gets into the question of when do you consider something a group expense and when do you consider it personal?
I mean sure, ammo used to kill enemies is obviously beneficial for the entire group, but then again, so is the sammy getting better reflexes. Sure it sucks to lose a drone as a rigger, but it also sucks to have to burn bound spirits as a mage.
If you just divide the money evenly then everyone can manage their own resources as they see fit. If the mage wants to go crazy summoning spirits, he can, but if he wants to be smart and only use them when needed, then he gets to make more money.
I admit that to some extent this might cause people to be overly conservative, with the sammy not wanting to use his really good ammo because it is so expensive, and the rigger not wanting to risk his shiny new drone, but I think that generally the desire to succeed at a mission far outweighs stinginess of resources.
