This study assessed the impact of unpaid caregiving on the likelihood of working and hours worked for caregivers and calculated the related cost of forgone earnings in 2013 and 2050. The current economic cost is about $67 billion, which by midcentury will likely double to $132–$147 billion. Opportunity cost per caregiver will likely increase by 8–20 percent and per US resident by 54–72 percent. Future policy action could benefit from accounting for the economic costs in addition to the benefits of unpaid caregiving, which would help define the scope and size of programs needed to support caregivers.
