Understanding 401(k) Plans and Retirement Savings Trends
Working Americans are increasingly focused on building financial security for retirement, aiming to cover basic needs while still enjoying the experiences they hope to have after decades of work. Over the years, many workers have relied on guidance from trusted sources to navigate the complexities of retirement planning.
A recent preview of the “How America Saves 2026” report by an investment company highlights that 401(k) participation and savings rates continue to rise, showing steady progress in how Americans prepare for their future. However, the data also reveals disparities among different groups of workers, particularly those with lower incomes or inconsistent access to employer-sponsored plans, who may be missing out on significant long-term retirement gains.
What Are 401(k) Plans?
A 401(k) is a feature of a qualified profit-sharing plan that allows employees to contribute a portion of their wages to individual accounts. According to the Internal Revenue Service (IRS), elective salary deferrals are excluded from the employee’s taxable income (except for designated Roth deferrals). Employers can also contribute to employees’ accounts, and distributions, including earnings, are includible in taxable income at retirement (except for qualified distributions of designated Roth accounts).
Vanguard’s Findings on 401(k) Participation
Vanguard’s report shows that while many 401(k) savers are doing well, participation rates vary significantly across different demographics. Income levels are a major determinant of retirement savings participation rates. For example, 31% of eligible employees with income less than $15,000 contributed to their employer’s DC plan in 2024, compared to 95% of employees with income over $150,000.
Age also plays a role in participation rates. Younger workers, particularly those under 25, had lower participation rates, with only 54% contributing to their employer’s plan. In contrast, more than 8 out of 10 employees between ages 35 and 64 made such deferrals.
Tenure at a job also influences participation. Employees with less than two years of tenure had a 70% participation rate, while nearly 9 out of 10 workers with four or more years of tenure participated in their employer’s plan.
Gender differences in participation were minimal overall but became more pronounced when considering income levels. At most income levels, women were more likely than men to join their employer’s plan. For instance, 88% of women earning $50,000 to $74,999 participated in their employer’s plan, compared to 84% of men in the same income group.
Industry Sector Impact on 401(k) Participation
Participation rates also varied by industry sector. Employees in finance, insurance, and real estate had the highest participation rates, with more than 9 out of 10 workers participating in their employer’s plan. In contrast, employees in wholesale and retail trade had the lowest participation rate at 75%.
Key figures from the report include:
- Finance, insurance, and real estate: 88% plan-weighted and 92% participant-weighted.
- Business, professional, and nonprofit: 87% plan-weighted and 81% participant-weighted.
- Transportation, utilities, and communications: 87% plan-weighted and 83% participant-weighted.
- Manufacturing: 86% plan-weighted and 90% participant-weighted.
- Media, entertainment, and leisure: 84% plan-weighted and 90% participant-weighted.
- Education and health: 81% plan-weighted and 85% participant-weighted.
- Agriculture, mining, and construction: 81% plan-weighted and 83% participant-weighted.
- Wholesale and retail trade: 75% plan-weighted and 53% participant-weighted.
Positive Trends in 401(k) Plan Designs
Despite these disparities, Vanguard found that strong 401(k) plan designs helped many stay on track with their retirement savings. Solid market returns and improved plan designs increased contributions to employer-sponsored retirement plans.
Automatic contribution solutions played a key role in increasing savings rates. Enhancements in automatic enrollment and increases in default saving rates have improved participants’ age-appropriate equity exposure.
The SECURE 2.0 Act and Automatic Enrollment
The SECURE 2.0 Act of 2022 requires automatic enrollment in 401(k) plans, making it easier for employees to start saving. This law mandates that employees are automatically enrolled in retirement plans unless they opt out. The initial automatic enrollment amount is at least 3% but not more than 10%, with annual increases until it reaches at least 10% but no more than 15%.
Research has shown that automatic enrollment significantly increases participation in retirement plans. People are more likely to participate if they don’t have to take action themselves.
