Investors often need to make assumptions about future asset returns in order to estimate how much they may need to save today in order to meet retirement-spending goals. We generally look to the past to project the future, but higher prices for stocks and bonds today suggest that investors can likely expect lower returns. Higher-earning Americans are also living longer, increasing the cost of funding a retirement income goal. It is important to recognize the planning implications of funding a longer retirement in a low-return environment.
