What sort of game? If an RPG, it shouldn't cost that much at all..
Say 8-12 pages of stuff to print out (cha sheets for pregens, or 3-5 sheets if using say house rules to build a PC with), and how ever many pages needed for the module you are running (if home made).
40-60 bucks if you are providing an extra copy or two of the base book for others to use in game (that you get back!)
5 bucks for some spare dice
3 bucks for some spare pens and pencils..
Just add the necessary information to the character sheets and avoid the cost of an extra copy or two of the base book for others to use in game.
You can get sets of dice for around $2 if you shop around and you can also share at the table. No need for each player to have their own set.
Get pencils at IKEA when you are the neighborhood or pens from the hotel you are crashing at. No need for erasers in a non-campaign game.
