Money Expert Reveals How Much You Should Have in Your 401(k) by Age and Why Most Americans Are Falling Short

A 401(k) account remains one of the most effective investment vehicles for building wealth for retirement, benefiting from employer contributions and a range of tax advantages. For 2026, the contribution limit stands at $24,500 (£17,893), with catch-up contributions of an additional $8,000 (£5,842) available for those aged 50 and over.

Average 401(k) Balances by Age

According to Vanguard, the average 401(k) balance in 2022 was $112,572 (£82,217). For those aged between 20 and 29, the average balance was just $14,600 (£10,663). This amount increased to $51,200 (£37,394) for individuals aged 30 to 39.

For the 40 to 49 age group, the average balance was $120,200 (£87,788). Those aged 50 to 59 had the highest average at $206,100 (£150,526). Despite these figures, a 2024 Fidelity report indicated that the overall average 401(k) balance had risen slightly to around $127,000 (£92,755). However, these amounts remain low if one's goal is to live comfortably in retirement.

How Much You Should Save in 401(k)s by Age

Sam Dogen, the author of Financial Samurai, who claims to have retired in 2012 after over a decade in investment banking, emphasises the importance of accumulating sufficient savings to achieve financial independence. Having maxed out his 401(k) contributions annually since 1999, he now holds over $1.6 million (£1.1 million) in his 401(k) and IRA rollover.

He suggests that by age 25, individuals should aim to have saved around $80,000 (£58,428). By age 35, a goal of $500,000 (£365,178) is recommended. By 45, he targets $1.5 million (£1 million), and by 55, at least $3 million (£2.1 million). Ultimately, he believes everyone should aim to be a 401(k) millionaire by age 60.

Why Most Americans Have Low 401(k) Savings

Many Americans are unaware that their employers offer 401(k) plans or employer-matching contributions. Others mistakenly believe that Social Security will be sufficient to cover their living expenses in retirement.

Additional factors contributing to low savings include inadequate contributions during working years, which diminishes the power of compounding, tax advantages, and free employer contributions. Kevin O'Leary from Shark Tank points out that spending habits also play a significant role; many people find it difficult to max out their 401(k)s because they spend more than they earn. This results in a large portion of income going towards repaying high-interest debts and rising bills, leaving little for future investments.

The author of Financial Samurai urges Americans to contribute the maximum possible pre-tax income to their 401(k)s throughout their working lives. Once employment ends, he recommends directing at least 20% of after-tax income into savings or other retirement accounts. He also cautions against relying heavily on Social Security, especially given the growing risks of benefit cuts.

O'Leary's Advice For Lowering Expenses

For those struggling to control their spending, O'Leary advises starting with a clear picture of your current finances. Begin by calculating your total income over the past three months. If pay stubs are unavailable, reviewing bank statements can help track cash inflows, including salaries, side gigs, or rental income.

Next, list all expenses, from small purchases like coffee or snacks to larger costs such as debt repayments, utility bills, and home maintenance. Subtract total expenses from total income. If the result is positive, individuals should consider increasing their monthly 401(k) contributions. If the figure is negative, adjustments are necessary to balance the books.

Achieving a comfortable retirement requires disciplined saving and strategic planning. Understanding how much to save at each age, recognising the importance of employer contributions and tax benefits, and managing spending habits are essential steps toward securing financial independence. As the landscape of retirement savings continues to evolve, staying informed and proactive can make all the difference in reaching your financial goals.
