Valuing the contribution of ultra-light buyers

Abstract

Ultra-light buyers, those who, on average, buy a brand once a year or less, are important by number and their contribution to brand purchase occasions. The initial research, however, was limited in scope and did not measure the contribution of these buyers to sales volume or value. By examining over 850 brands in almost 60 categories, we identify that ultra-lights make up 62% of a brand's buyer base over 5 years and contribute 32% of purchase occasions and 31% of sales volume and value. In line with previous findings that brands with higher loyalty exhibit more repeat purchases and thus fewer ultra-light buyers and private label brands often exhibit higher than expected loyalty for their market share—we find the prevalence of ultra-light buyers is higher for national brands than private labels, likely reflecting the higher loyalty often observed for private labels. We also find no difference in ultra-light buyers' contribution between high and low-price brands, indicating that price is not a significant factor affecting the contribution of ultra-light buyers. Finally, we find that both growing and declining brands have fewer ultra-lights than stable brands. As growth occurs via increasing penetration and loyalty, for growing brands, new buyers may be more ‘light’ than ‘ultra-light’ in terms of their loyalty; while for declines, these findings imply that there are not enough ultra-light buyers to maintain brand sales. A failure to recruit ultra-light buyers may be very dangerous for brand health.
