Many people reach their mid-40s with little or no retirement savings, so if you are already sitting on $1 million at that age, you are in an excellent position. To put that in perspective, Empower data show the average 401(k) balance for people in their 40s is $370,879, with a median of just $154,212. A seven-figure balance at 46 puts you well ahead of the vast majority of American savers.
Still, a million dollars is not the golden ticket it used to be. It may cover your basic expenses comfortably, but it probably will not fund a truly lavish retirement. Wanting to double that amount before leaving the workforce is completely reasonable, and the math is more encouraging than most people expect.
In this Reddit thread, a 46-year-old saver has already crossed the million-dollar mark but wants to keep building. If that balance can grow to $2 million by retirement, their later years could be far more relaxed and financially secure.
The good news is that this goal is entirely within reach. With the right strategy, discipline, and long-term planning, doubling a $1 million portfolio over the next couple of decades is realistic. Anyone in a similar situation can use the same core tactics to boost their chances of success.
Keep funding that retirement plan to the max
If you are in your mid-40s with $1 million saved and aiming to reach $2 million by a typical retirement age, history is on your side. According to Fidelity, the S&P 500’s average annual return has been about 10% since the index’s launch in 1957, and the 20-year average return from January 2006 through December 2025 came in at 11%, a period that included the 2007 housing crisis and the COVID-19 market crash. At a conservative 8% annual return over 20 years, $1 million grows to roughly $4.66 million. At 10%, that figure climbs to about $6.73 million. The real question, in other words, is not whether you can reach $2 million but how far beyond it your balance might go. Of course, market volatility, inflation, sequence-of-returns risk, and future spending needs all play a role, so maintaining a well-diversified allocation is critical.
Your timeline matters enormously. Someone planning to retire at 55 faces a very different savings runway than someone targeting 65 or 67. The shorter the window, the more important it becomes to maximize every contribution and manage the portfolio’s risk profile carefully.
Maxing out your 401(k) each year remains one of the most reliable levers available. For 2026, the IRS has set the employee deferral limit at $24,500, up from $23,500 in 2025. Once you turn 50, you gain access to catch-up contributions: an additional $8,000 per year in 2026 for a total of $32,500. The SECURE 2.0 Act also introduced a “super catch-up” for savers ages 60 to 63, who can contribute an extra $11,250 instead of the standard $8,000, bringing their total possible deferral to $35,750. On top of that, the 2026 IRA contribution limit is $7,500, with a $1,100 catch-up for those 50 and older. Each dollar you add now compounds over time, while also reducing your taxable income today.
Starting in 2026, one important wrinkle affects high earners. Anyone who earned more than $150,000 in FICA wages in 2025 is now required to make catch-up contributions on a Roth basis in employer-sponsored plans. If your plan does not yet offer a Roth option, check with your plan administrator, because without one, high earners cannot make catch-up contributions at all under the new rules.
Work with a financial advisor to meet your goals
A $2 million nest egg by your mid-60s is more than achievable if you already have $1 million saved in your mid-40s. Even without adding another dollar, your existing balance should continue to grow over time as long as it remains invested. But continuing to contribute, especially as catch-up limits expand, can dramatically accelerate that timeline.
Even if you are already in a strong position, speaking with a financial advisor is a smart move. An advisor can review your portfolio’s allocation, make sure it is positioned for the growth you need, and help you map out a realistic retirement age based on your personal spending expectations, Social Security timing, and any other income sources you anticipate. The combination of compounding returns and strategic contributions gives a 46-year-old with $1 million a genuinely powerful head start.
Editor’s note: This article has been updated to reflect 2026 IRS contribution limits, including the new $24,500 base 401(k) deferral, the $8,000 catch-up for savers 50 and older, the $11,250 “super catch-up” for ages 60 to 63 introduced under the SECURE 2.0 Act, and the requirement that high earners above $150,000 in prior-year FICA wages direct catch-up contributions to Roth accounts beginning in 2026. Current average 401(k) balance data from Empower and updated S&P 500 long-term return figures from Fidelity have also been incorporated.
