In 401(k) plans with automatic enrollment — meaning employees must opt out if they don't want to participate — 93% of both men and women remain signed up, according to a report from Vanguard.
But in plans whose enrollment is voluntary — workers have to actively enroll — men lag behind women in participation rates at all income levels, most notably below $150,000.
The largest difference is in the $50,000-to-$74,999 income range, with 81% of women participating versus 67% for men.
Men earn more and save a larger share of itThe average 401(k) balance among men in 2021 was $93,512, compared with $70,037 among women, the Vanguard research shows.
Overall, however, both women's and men's participation rate — 68% and 65%, respectively — in voluntary enrollment plans is much lower than the 93% rate in auto-enrollment plans.
