How Long Will $500,000 Last in Retirement? Year-by-Year Breakdown (2026)

The table above is a starting point, not a forecast. These five factors routinely add or subtract 5–10 years from portfolio life:

1. Sequence-of-Returns Risk

If the stock market drops 30% in your first two years of retirement, your $500,000 becomes $350,000 before you've even withdrawn much. Pulling $20,000/year from a depleted base accelerates the drain. Trinity Study data shows that identical average returns can produce vastly different outcomes depending on when the bad years fall. A retiree who started in 2000 (dot-com crash) had a fundamentally different experience than one who started in 2009 (bull market), even at the same withdrawal rate. This is the single biggest reason a fixed percentage isn't the full answer.

2. Social Security Timing

Claiming Social Security at 62 versus 70 changes the monthly benefit by roughly 77% — about $1,400/month versus $2,480/month on a $75,000 career average salary (see our full Social Security breakdown). Every dollar Social Security covers is a dollar your $500k doesn't need to provide. Delaying to 70 while drawing down savings from 62–70 often extends total portfolio life, because the higher guaranteed income permanently reduces the withdrawal rate on your investments.

3. Inflation

The Federal Reserve targets 2% annual inflation, but the 2021–2023 period showed that actual inflation can surge well above that. At 3% average inflation, $20,000 in year one needs to become $26,878 by year 10 just to buy the same goods. If you don't increase withdrawals for inflation, you maintain the portfolio but quietly accept a falling standard of living. The Inflation-Adjusted Return Calculator shows exactly how inflation erodes purchasing power at any rate.

4. Investment Allocation

A 100% bond portfolio at today's yields (~4.5%) on $500,000 generates $22,500/year but offers minimal growth to offset inflation. A 100% stock portfolio has historically returned 10% nominal but with drawdowns that can exceed 50%. The research consensus — including the original Trinity Study and updated work by Wade Pfau at the American College of Financial Services — suggests a 50/60% equity allocation optimizes longevity for 25–30 year horizons.

5. Fees and Taxes

A 1% annual advisory fee on $500,000 costs $5,000 in year one — that's 25% of a $20,000 annual withdrawal going to fees rather than spending. Over 25 years, fee drag at 1% versus 0.2% costs roughly $60,000–$80,000 in cumulative portfolio value. Similarly, withdrawals from traditional IRAs and 401(k)s are taxed as ordinary income, while Roth withdrawals are tax-free. The tax treatment changes how much you actually keep from each dollar withdrawn.

Most Americans don't live on savings alone. About 97% of people 65 and older receive Social Security (SSA Quick Statistics, 2025). Here's how $500,000 performs when paired with typical benefit amounts:

The pattern is clear: for retirees with average Social Security benefits and moderate spending, $500,000 is often sufficient for a 30-year retirement. The risk zone is when monthly spending exceeds $4,500 for a single person or $6,500 for a couple, pushing the annual draw above 6% of the portfolio.

If the numbers above feel tight, these research-backed approaches extend portfolio life without requiring more savings:

1. Use a Dynamic Withdrawal Strategy

Instead of withdrawing a fixed dollar amount, adjust spending based on portfolio performance. The "guardrails" method — cutting withdrawals by 10% when the portfolio drops below a floor and increasing by 10% when it exceeds a ceiling — historically improved 30-year success rates from 82% to 95% in Monte Carlo simulations (Guyton-Klinger research). Your spending flexes, but your money lasts.

2. Delay Social Security to 70

Every year you delay Social Security past 62 increases your benefit by approximately 6–8% per year, and benefits are inflation-adjusted for life. Using $500,000 to bridge the gap from 62 to 70 costs roughly $120,000–$160,000 in early drawdowns but buys a permanently higher income floor. For someone expecting to live past 80, the breakeven math strongly favors delaying. Our Social Security benefit guide shows the exact dollar difference at each claiming age.

3. Minimize Fees

Moving from a 1% advisory fee to a 0.15% index fund portfolio saves roughly $4,250/year on $500,000. Over 25 years of compounding, that difference preserves $60,000–$80,000 in portfolio value — effectively adding 3+ years of withdrawals at a 4% rate. Vanguard, Fidelity, and Schwab all offer total market index funds with expense ratios under 0.05%.

4. Consider Partial Annuitization

Putting $100,000–$150,000 of the $500,000 into a single-premium immediate annuity creates a guaranteed income floor regardless of market performance. This reduces the investable portfolio to $350,000–$400,000 but also reduces the annual withdrawal needed from investments, lowering sequence-of-returns risk. Our annuity payout guide shows exactly what different premium amounts generate in monthly income.
