The S&P 500 (SPY) returned 19.43% over one year as of January 2026. Working one more year could grow a $3M portfolio to $3.36M through market appreciation and contributions.

The additional year permanently increases sustainable annual S&P 500 portfolio withdrawals from $120K to $134.4K using the 4% rule.

A recent study identified one single habit that doubled Americans’ retirement savings and moved retirement from dream, to reality. Read more here.

At 58 with $3 million saved, working one additional year represents one of the most financially consequential retirement planning decisions. For many near-retirees, “one more year syndrome” becomes a recurring dilemma, as one Reddit user described watching others repeatedly delay retirement despite having sufficient resources. The math behind that single year reveals why this decision deserves serious consideration.

Age: 58 years old

Current Portfolio: $3 million in retirement savings

Decision Point: Retire now or work one more year

Key Tension: Balancing immediate freedom against enhanced financial security

Critical Factor: Compounding effect of contributions plus market returns

This scenario mirrors similar situations faced by professionals approaching 60 who wonder if they’ve reached their financial finish line.

A single additional working year delivers a triple benefit. First, you avoid withdrawing from your portfolio, preserving capital. Second, your existing $3 million continues growing. Assuming a 7% annual return (conservative compared to the S&P 500’s recent 19.43% one-year performance as of January 2026), that’s $210,000 in market appreciation. Third, you’re likely contributing substantial additional savings.

Earning $150,000 and maximizing retirement contributions could add another $150,000 to the portfolio. Combined with market growth, that single year could increase your nest egg to approximately $3.36 million. Using the 4% safe withdrawal rate, this shifts your sustainable annual income from $120,000 to $134,400, a 12% permanent increase in spending power throughout retirement.

An infographic titled 'A 58-Year-Old With $3 Million Is Debating Whether to Work One More Year'. It presents a scenario at a glance, showing icons for Age (58), Current Portfolio ($3 Million), Decision Point (Retire now or Work one more year), Key Tension (Balancing immediate freedom vs. enhanced financial security), and Critical Factor (Compounding effect of contributions + market returns). The central section, 'The Financial Reality of One More Year: A Triple Benefit', compares two paths: 'Retire Now (Age 58)' and 'Work One More Year (Age 59)'. For 'Retire Now', a $3,000,000 portfolio leads to a $120,000 annual withdrawal (4% rule) and a $3,600,000 30-year total income. For 'Work One More Year', the initial portfolio plus $210,000 market appreciation (7% assumed) and $150,000 additional contributions results in an estimated portfolio of $3,360,000. This leads to a $134,400 annual withdrawal, a permanent annual increase of $14,400 (a 12% increase in spending power), and a $4,032,000 30-year total income. Below this are 'Market & Economic Context' with line graphs: Equity Market (S&P 500) showing a 1-year return of +19.43% (as of Jan 2026) and 'Mixed-to-Bullish' sentiment, and Bond Market (AGG) showing a 1-year return of +8.8% (as of Jan 2026) and 'Declining Environment' for interest rates. 'Additional Considerations' include sections on 'Tax & Healthcare', 'Strategic Paths', and 'Evaluate Now', detailing factors like health insurance, IRA withdrawals, part-time work, and calculating spending. Final thoughts emphasize balancing finance and life, stating the decision isn't purely financial. 24/7 Wall St. · 24/7 Wall St.

This infographic details the financial benefits and considerations for a 58-year-old with a $3 million portfolio debating whether to work one additional year versus retiring immediately.

 

Tax implications matter significantly. Working another year means one fewer year of healthcare premiums before Medicare eligibility at 65. At 58, you’re facing seven years of private insurance costing $15,000 to $25,000 annually for quality coverage. Delaying retirement to 59 reduces that exposure by one year and brings you closer to penalty-free IRA withdrawals at 59½.

Story Continues

If your job is tolerable and your health is good, working one more year provides measurable security. That extra $14,400 in annual withdrawal capacity compounds over a 30-year retirement to potentially hundreds of thousands in additional spending power.

However, if you’re facing burnout or health concerns, the calculus shifts. $3 million already supports a comfortable retirement with proper asset allocation. A balanced portfolio split between equity exposure (through broad market funds tracking the S&P 500, which has returned 82.37% over five years) and fixed income (bonds have returned 8.8% over the past year) can sustain withdrawals while managing volatility.

Consider a middle path: negotiate part-time work or consulting arrangements. This provides continued income and benefits while reclaiming significant personal time.

Calculate your actual spending needs by tracking 12 months of expenses. Price healthcare coverage in your state through ACA marketplaces to quantify this major expense. Model your portfolio’s sensitivity to market downturns, since retiring into a bear market creates sequence-of-returns risk that working through would avoid.

The biggest mistake is treating this as purely a financial decision when it’s equally about life satisfaction. One more year at 58 is different than one more year at 68. The opportunity cost of delaying retirement includes the time, health, and energy you have right now.

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.

And no, it’s got nothing to do with increasing your income, savings, clipping coupons, or even cutting back on your lifestyle. It’s much more straightforward (and powerful) than any of that. Frankly, it’s shocking more people don’t adopt the habit given how easy it is.
