We're sort of "loose" when it comes to finances/budgeting. Our pack pretty much seems to spend what we bring in in popcorn sales. I inherited a bank balance that is higher than what most units tend to carry, and haven't really dented it all that much.
That said, we charge $55 for the year (just raised this year). $27(?) or whatever, goes to BSA/Boys Life/insurance, and we committed that the rest goes right to den budget.
This is a great selling point to parents - with the exception of the BSA-end... all of their money goes directly to their kids dens, and not Pack general funds. What den leaders don't spend, of course, does revert to the pack.
The rest is covered by popcorn sales. We cover all awards - even belt loops, vest segments. We do a "rank promotion" ceremony at our May pack meeting where the pack pays for their neckerchief for the next rank. W2's get a flint and steel on a scout keychain.
Our April pack meetings have been at a place with the big inflatables - we'll pick up the Scout costs for that as well. Most other things with admissions/fees, the Scouts/families pay the admission for.
We charge a nominal fee for Blue and Gold - about $8 per person, Scouts are free.
