Here’s what you need to know about this calculator:

  1. You need to have TWO CONSECUTIVE YEARS of COMPLETE donor data to compare.
  2. YEAR TWO donors is NOT the number of donors in YEAR TWO. It is the number of donors who gave in BOTH years.
  3. Retention of donors from one program or campaign may be higher or lower depending upon stewardship activity for that specific program, which could cause an inaccuracy in the results. To measure retention rates for one specific program, enter data for only that program.
