We're near Little Rock, Arkansas, so our structure will be a little different, but still similar to other suburban lodges:
Lodge dues are $60 per year. Perpetual membership (what GLoTX terms "endowment") is indexed to lodge dues, 16 times the annual dues payment at the time you endow. We currently have 80 dues-paying members, and 57 perpetual, or endowed members. Grand Lodge per capita fee is $10 per member since 2007, $5 per member for those perpetual guys who paid in before 2007. For our endowed/perpetual members, we received an average of $16.50 back from the Grand Lodge this year.
We are currently looking at raising dues, probably to the $100 to $120/year level at our December meeting. Several other lodges, such as Conway, are already at the $100 level. And having done the math for this little exercise, I definitely see that the perpetual memberships are a derned good deal for the brother, but not so much for the lodge, once you start trying to work out next year's budget ;-)
