Will everyone actually have the book by meeting night?
Enter your roster, your kit copies and your typical hold wait, and see how many readers are short and how early the title has to be locked.
The most common reason a discussion falls flat is not the book. It is that four people did not get a copy in time, read the first sixty pages on a phone sample, and spend the evening being carefully vague. That failure is scheduled weeks earlier, on the day the group decided which title it was reading, and it is entirely avoidable with arithmetic.
This planner works backward from meeting night. It counts how many readers your kit and your members own copies actually cover, shows the shortfall you have to solve with holds, purchases or interlibrary loan, and adds your typical wait to the reading time a normal member needs. The result is the number of weeks before the meeting that the vote has to close.

How far before the meeting the title has to be settled and requested.
Add another week of lead time in January and in the weeks after a title wins a major award, when holds run long.
Lead time is set by the slowest reader, not the fastest
Hosts plan around themselves, and hosts read fast. The member who reads forty pages on a Sunday evening needs the full four weeks and cannot start until the book is physically in her hands. If your hold queue runs three weeks, that member needs the title announced seven weeks out, not three.
This is why the fourth month is when groups lose people. The first three titles were picked early because the club was new and excited. By month four the vote is happening a fortnight out, the holds do not land, three people arrive unprepared, feel awkward, and skip the next one. Fixing the calendar fixes most of that attrition without any conversation about commitment.
Closing the gap when the number comes back short
A shortfall of one or two is normal and easy. Members who own the book pass it along after they finish, someone reads the large print edition, and one person listens to the audio version. A shortfall of five is a different problem and means the title is wrong for this month rather than that your members are disorganized.
Practical fixes in order of cost: reserve a second kit from another branch in the same system, place a bulk of individual holds early so the queue positions are yours, file interlibrary loan requests for the two or three members willing to wait, ask the branch about purchase on patron demand, and only then buy copies. Running that sequence in advance is what the lead time number buys you.
Questions about this calculator
What is a realistic attendance share for a monthly group?
Settled groups usually see somewhere between half and two thirds of the roster on a given night. New groups run higher for the first few months and then settle. Use your own last six meetings if you have the record, because the average matters more than any single strong month.
Should I count audiobook listeners as covered?
Count them if your library lends the audio edition without a long queue and your group is comfortable with listeners in the discussion. Digital audio and ebook holds often move faster than print, so listing them as a route is legitimate. Just be sure the edition matches when the discussion turns on specific passages.
How far ahead can we realistically reserve a book club kit?
It varies by system, and many take reservations several months out, which is exactly why voting early pays. If your calculated lead time is seven weeks, running your vote three months ahead costs nothing extra and gives you first choice of kit dates for the whole quarter.

The run sheet for one month of a book club
Everything a host actually has to do between one meeting and the next, in the order it has to happen, with the deadlines that make copies arrive on time.
Keep that figure true past this title
One run of this calculator tells you where the club stands with the book you are reading now. Staying accurate takes attendance recorded on the night, kit reservations logged with their return dates and a note of who hosted, month after month. A demo shows how the running headcount and the copy shortfall update themselves so you are not rebuilding the same spreadsheet every cycle.
