What your chapter dues have to cover before anything reaches the programs
Enter your roster count, your dues figure and the money that leaves before you can spend a dollar, and see the surplus and the break-even member count.
Free tools
Two free calculators built from the arithmetic volunteer officers actually run before a board meeting, with no sign up in the way.
Both tools start with sensible defaults for a chapter of around one hundred members so you can see a real answer before touching anything. Change the numbers to your own roster count, your own dues figure and the share your national body takes, and the results move with you.
Neither calculator asks for an email address. Print the screen for the board packet if that helps, or read the notes under each result to see exactly which assumption is doing the work. If your chapter runs a monthly tier or a life membership category, run the numbers once per category rather than blending them into a single average.

Put in your roster size, how many pay on the first notice and how you chase the rest, and see the hours your officers spend before dues are closed.
Working document
Everything the outgoing treasurer of a chapter or alumnae association should close, assemble, transfer and verify so the next woman starts with a book that balances.
Every chapter treasurer has run this arithmetic on the back of a board agenda: dues times paying members, minus the per capita the national body takes, minus what the card processor keeps, minus insurance and the state charitable registration fee, and then the awkward question of how many women have to renew before the chapter starts spending reserves. The membership chair runs her own version of it, counting the alumnae still unpaid after the first notice and multiplying by the minutes each chase takes. Neither calculation is difficult. Both are tedious enough that most chapters do them once in September and never redo them when the roster drops by fifteen.
So both tools sit here with no email form in front of them. Work out your break-even member count before the budget meeting, print the screen for the board packet, and put the figures in the minutes without crediting us. They are worth having on their own terms: a dues figure you can defend when someone asks why it went up, and a weekly hours number you can hold beside what a volunteer officer with a full time job can honestly give you during renewal season. If your chapter runs an early career rate or a life membership category, run each one separately rather than blending them.
Both calculators work from figures you typed in, which means they are only as good as your last roster count, and by year three that count is usually a guess. In a demo we import your member list, catch the alumnae who appear twice under a maiden name and a married one, and show the same arithmetic running off real dues history. Twenty minutes, and the export is yours whatever you decide.
