Rising health care costs threaten financial security at older ages and lead many older Americans to delay retirement. Continued work reduces the risk of high out-of-pocket health care costs for workers receiving health benefits from their employers. Working longer also increases retirement incomes, making health care costs more affordable. This report shows that men with very high expected health care costs after age 65 retire 11 months later than those with very low health care costs. For women, the difference is 12 months.
