A savings rate of 40% “is still not 100,” said Motohiro Yogo, an economics professor at Princeton. “But doubling from 21 to 40 is still a pretty good gain.”
Yogo and his colleagues, Natalie Cox at Princeton and Andrew Whitten at the Treasury, published preliminary findings in 2023. Their work continues: Yogo said the 40% savings rate is a new, as-yet-unpublished data point.
The study focuses on lower-income workers because higher-income Americans don’t need help saving for retirement: most of them are already doing so.
Retirement savings advocates applaud the new automated savings programs that have popped up around the country over the past few years. Collectively, the initiatives have enrolled more than 800,000 workers, who have saved at least $1.5 billion, according to research by the Pew Charitable Trusts and Georgetown University.
