Is $600,000 Enough to Retire? What the Numbers Actually Say

With $600,000 saved for retirement, you stand ahead of most Americans. According to Fidelity’s Q1 2026 retirement analysis, the average 401(k) balance among Baby Boomers is $260,300, while the average IRA balance for that generation sits at $286,700. The 401(k) figures come from 25.6 million plan participants across 26,800 corporate defined contribution plans, and the IRA figures are drawn from 19.6 million accounts, both tracked through March 31, 2026.

Standing above average on paper, however, does not automatically translate to financial security. The real question is whether $600,000 can carry you through two or three decades of retirement, or whether you need to keep building. Here is what the numbers reveal.

How much income does $600,000 in retirement investments produce?

A $600,000 portfolio is substantial, but it must last for decades, and that creates a core tension: withdraw too aggressively and you risk depleting accounts far too early; withdraw too conservatively and you sacrifice quality of life unnecessarily. Striking the right balance requires a reliable benchmark.

The 4% rule is the most widely cited starting point. The framework calls for withdrawing 4% of your portfolio in year one, then adjusting that dollar amount upward each year for inflation, with the goal of sustaining income across a 30-year retirement. Expert guidance, though, varies more than that single number suggests. Morningstar’s 2025 State of Retirement Income report recommends a 3.9% starting withdrawal rate, up from 3.7% the prior year, based on a 90% probability of funds remaining after 30 years in a balanced portfolio. Retirees who adopt flexible strategies, trimming withdrawals in down markets and increasing them in stronger ones, can push that sustainable rate as high as 5.7%, according to the same research. William Bengen, the financial planner who originated the 4% rule, has since revised his own worst-case estimate to 4.7% for portfolios built with broader diversification beyond traditional stocks and bonds.

Under the traditional 4% guideline, a $600,000 nest egg produces $24,000 in the first year. You then adjust that dollar figure upward for inflation each year. If inflation runs at 2.5%, your second-year withdrawal rises to $24,600, preserving purchasing power while keeping capital intact over the long term.

Can you live on $600K as a retiree?

Knowing your portfolio can generate roughly $24,000 a year answers only half the question. Whether that income is enough depends entirely on your personal circumstances, and two variables matter most: your preretirement earnings and the lifestyle you expect to maintain.

Someone who earned $60,000 annually before retiring may find $24,000 from savings, layered on top of Social Security, more than adequate. A higher earner accustomed to $120,000 per year faces a much larger income gap. As of June 2026, the average Social Security retirement benefit reached $2,084.40 per month, or approximately $25,013 annually, according to the SSA’s June Monthly Statistical Snapshot. Combined with $24,000 in portfolio withdrawals, that brings total income to roughly $49,000 before taxes for someone receiving average Social Security. The 2026 COLA was 2.8%, confirmed by the SSA’s official fact sheet, adding about $56 per month to the typical check compared with 2025.

Healthcare is another critical variable, and one that catches many retirees off guard. Retiring before age 65 means covering health insurance premiums entirely on your own until Medicare eligibility begins. Even after Medicare kicks in, out-of-pocket costs accumulate quickly. In 2026, the standard Medicare Part B premium rose to $202.90 per month, up $17.90 (nearly 10%) from $185 in 2025, while the annual Part B deductible increased to $283, up $26 from 2025. That premium increase alone outpaces the 2.8% COLA, illustrating how medical inflation erodes purchasing power even after government adjustments. For a healthy 65-year-old couple retiring in 2026, total annual healthcare costs including Medicare Part B, Part D, Medigap, dental premiums, and out-of-pocket expenses can start around $17,000 in year one and are projected to climb substantially as medical needs grow with age.

Timing matters deeply. A 55-year-old retiree needs savings to stretch 35 or 40 years, creating far more pressure on each dollar than a 67-year-old faces with a shorter horizon. Fidelity’s Q1 2026 data offers an encouraging benchmark for disciplined savers: participants who contributed to the same 401(k) plan for 15 consecutive years averaged $648,800 across all account types, with the total 401(k) savings rate reaching a record 14.4%. Baby Boomers in the 15-year continuous-saver group specifically averaged over $576,000, making $600,000 a realistic target for anyone who has saved steadily over a long career.

For some retirees, $24,000 annually from investments, combined with Social Security and careful healthcare planning, delivers a comfortable financial cushion. For those retiring early, living in high-cost areas, or managing chronic health conditions, that same figure can fall well short. A financial advisor can help you model your specific income needs, stress-test your plan against inflation and rising healthcare costs, and determine whether $600,000 gives you the security you are aiming for.

Editor’s note: This update refreshes the average Social Security retirement benefit to the June 2026 SSA Monthly Statistical Snapshot figure of $2,084.40 per month (approximately $25,013 annually) and adds the 2026 Medicare Part B annual deductible of $283, which rose $26 from 2025.
