Calculating retirement savings needs is often viewed as an essential first step in retirement planning. Yet, little empirical evidence exists to support the value of this activity. This case study examines the connection between calculating retirement savings needs and retirement savings through analysis of an online survey of benefits-eligible employees at a large Mountain West university. Controlling for a variety of possible covariates, and using an instrumental variable approach, the case study shows that having estimated a retirement savings target increases self-reported retirement savings. The results provide support for financial educators and planners in their efforts to encourage people to estimate their retirement needs early in the retirement planning process.
