A processing fluency perspective on overhead aversion: How much is too much?

Abstract

AbstractOverhead aversion has afflicted the nonprofit sector in recent decades. Yet, questions remain regarding how high is too high from a donor perspective and at what level overhead expenses just “feel right.” Using processing fluency as a theoretical foundation, the central purpose of this research was to investigate whether a nonprofit overhead ratio fluency level exists that significantly reduces both donation likelihood and nonprofit perceptions. Results from two studies show that a 25% overhead ratio appears to be the proximate ceiling regarding what fluently fits within a potential donor's schema for acceptance. Overhead ratios exceeding this threshold tended to decrease donation likelihood and nonprofit perceptions in a relatively stable manner. Moreover, the 25% threshold seems most relevant to human and animal causes and not as relevant to arts and cultural nonprofits such as museums. The results suggest that donors have a preconceived overhead ratio limit. Nonprofits that exceed that threshold are in danger of deterring donors. If nonprofit overhead ratios exceed the donor fluency threshold, nonprofit managers should consider distinct promotional strategies that entice donors and diminish overhead aversion effects.
