A 58-Year-Old With $3 Million Faces the Most Expensive Retirement Decision

"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. The Scenario at a Glance Age: 58 years old Current Portfolio: $3 million in retirement savings Decision Point: Retire now or work one more year"

"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.

Applying a 4% safe withdrawal rate increases sustainable annual income from $120,000 to $134,400, a 12% permanent boost. Continued work also avoids withdrawals and reduces years of private health insurance before Medicare, each saving $15,000–$25,000 annually. Tax impacts and individual spending needs should guide the decision.
