Although time is a finite resource, much sociological research suggests a positive association between engagement in informal helping activities and formal volunteering. However, it remains unclear whether this relationship is causal and, if so, in which direction the causality runs. To address these issues, I draw on two-wave panel data from Denmark. Using a cross-lagged panel model, I find no evidence that formal volunteering hours affect informal helping activities. However, in the reverse direction, I find evidence of a right-skewed inverse U-shaped relationship. Specifically, the time individuals dedicate to formal volunteering marginally increases with time allocated to informal helping activities, but only as long as their informal helping obligations remain modest. However, once these informal helping obligations reach approximately 20 hours, the time individuals spend on formal volunteering decreases with informal helping hours. These findings suggest that even exceptionally helpful individuals, often referred to as “super-helpers,” must balance their acts of kindness and their available time and energy. Moreover, I argue that while many people are motivated to engage in formal volunteering to benefit others, those with family and friends requiring assistance tend to prioritize these responsibilities before volunteering.
