Has anyone worked out a way to calculate a rolling donor retention rate? How many donors who gave in 2010 also gave in 2011? How many who gave in 2011 also gave in 2012? and so on for each year. Then, what is the percentage change from the 2011 retention rate to the 2012 retention rate?
Hi Don, just to clarify, are you asking about a rollup field that will do this automatically, or creating a report that would show this?
If I had a report, I could buld a graph on it, which is what I hope for.
