Measuring retirement resource adequacy

  • PETER J. BRADY (a1)


To maintain their standard of living during retirement, it is often assumed that individuals need to save enough to replace 75–80% of their final pay. This paper develops a replacement rate measure that better corresponds with a replacement of consumption by properly accounting for savings, taxes, and owner-occupied housing. Savings and investment behavior judged by standard analysis to be inadequate is shown to result in high real consumption during retirement relative to pre-retirement consumption. For example, the simulated savings and investment behavior of single individuals in this study results in retirement income of about 60% of final earnings, well below the typical adequacy threshold of 75–80%. However, this corresponds to replacing about 90% of pre-retirement consumption for renters and over 100% for homeowners who have paid off their mortgage.
