Chuck Longfield is worried about the future of fundraising because acquisition costs have increased while donor retention has decreased from 33% to 27% over the past 10 years. Specifically, 75% of newly acquired donors leave within the first year. While the number of new donors decreased 20% from 2003 to 2007, the average donation amount rose 23%. Most nonprofits prioritize acquisition goals over retention goals despite retention costing five times less. This overemphasis on acquisition risks losing loyal donors over time and lowers net profits for nonprofits. To improve retention, nonprofits should invest in existing donors by learning their passions and building relationships with the most promising donors.
