The calculator is based on industry standards that fundraising professionals have been using for decades. The formulas are proprietary.

When you enter your goal amount and click Calculate, the algorithm determines:
  • the cumulative percentages from 10% to 100%.
  • the subtotals are then calculated
  • the gift ranges are selected
  • the number of gifts is determined
  • the number of prospects needed to contact to achieve the number of gifts is determined
