A 67-Year-Old Single Retiree With $920,000 Can Stretch It to Age 95 If the COLA Holds Above 2 Percent

A 67-year-old retiree with $920,000 in savings and a $2,800 monthly Social Security benefit appears to have a comfortable setup. With annual spending totaling $58,000, the portfolio only needs to generate about $24,400 per year to close the gap, resulting in a withdrawal rate of roughly 3%. By retirement-planning standards, that figure looks exceptionally safe and well within the range many advisors consider sustainable.

The challenge is that retirement math rarely stays frozen in time. The biggest wildcard is how much Social Security benefits grow through future cost-of-living adjustments over the next 28 years. Even small differences in inflation and COLA growth compound dramatically over decades, determining whether a retiree maintains purchasing power or gradually falls behind rising costs. What looks stable at 67 can become far more precarious by 87.

Recent COLA history adds useful context. The 2025 adjustment came in at 2.5%, and the 2026 COLA reached 2.8%, both above the article’s critical 2% threshold. The decade average sits near 3.1%. With headline CPI running at 4.2% through May 2026, early estimates suggest the 2027 COLA could track considerably higher still. For this retiree, that trajectory matters more than almost any other single variable in the plan.

Why 95 Is the Right Planning Horizon

SSA Period Life Table data implies a healthy 67-year-old woman has roughly a 50% chance of reaching 88, a 25% chance of reaching 93, and a 10% chance of reaching 96. Planning to 95 is the responsible tail. Stretching $920,000 across 28 years requires the portfolio to do real work without taking on equity-like risk in years it cannot afford a drawdown.

The $24,400 Yield Math at Three Risk Levels

The portfolio only has to cover the gap between spending and Social Security. Here is what that gap costs at three yield tiers, using current market reference points.

Conservative tier, 3% to 4%. Broad dividend growth equity funds, investment-grade bond ladders, and Treasury notes anchor this tier. The 10-year Treasury trades near 4.5% and the 30-year recently crossed back above 5%, which means a laddered Treasury sleeve alone produces more than enough yield on a modest slice of capital. To generate the full $24,400 at 3.5%, the math requires about $697,000 of dedicated capital. The remaining portion of the $920,000 can stay growth-oriented to fund years 15 through 28.

Moderate tier, 5% to 7%. REITs, preferred shares, covered-call equity funds, and high-dividend value strategies live here. At 6%, producing $24,400 requires about $407,000 of dedicated income capital, freeing up more than half the portfolio for growth. The tradeoff: distributions in this tier rarely keep up with inflation, and covered-call funds surrender the upside that compounds a 28-year plan.

Aggressive tier, 8% to 14%. Business development companies, mortgage REITs, and leveraged option-income funds can cover the gap on a much smaller capital base. At 10%, the math requires just $244,000. The risk is principal erosion. A retiree who funds the gap from a 10% distribution and watches underlying NAV slide 3% to 5% a year is spending the asset, not living off it.

The COLA Variable That Breaks or Makes the Plan

This is where the headline condition matters most. Headline CPI is running at 4.2% above year-ago levels as of May 2026, the kind of inflation environment that has historically supported a healthy COLA. Core PCE is rising at 3.41% year-over-year, well above the Fed’s 2% target. The Fed held its upper bound at 3.75% for a fourth consecutive meeting on June 17, 2026, as policymakers weighed persistent inflation against a resilient labor market.

Run two scenarios with the same starting check. If COLA averages 2.5% a year, the Social Security benefit grows to roughly $66,000 by age 95. If COLA averages only 1.8%, it grows to about $54,000, a $12,000 annual shortfall the portfolio must cover. Over a decade in the 90s, that gap compounds into hundreds of thousands of dollars of additional drawdown. At 4% portfolio growth net of 2% spending inflation, the real balance at 95 lands somewhere between $720,000 and $1.1 million, depending entirely on which COLA path actually materializes. Given that both the 2025 and 2026 COLAs landed above 2.5%, the optimistic scenario is currently more consistent with recent history.

Three Moves That Buy Margin

1. Build a 24-month cash reserve. Holding two years of the $24,400 gap in T-bills or a money market fund means a market downturn never forces a portfolio sale at the bottom. Short Treasury yields near 3.6% pay the retiree to wait while keeping the buffer liquid.
2. Plan a modest annuitization window at 75 to 80. A $150,000 SPIA purchased in that window could pay roughly $1,200 a month for life, which amounts to longevity insurance for the tail past 90. With the 30-year yield back above 5%, annuity pricing remains favorable relative to recent years.
3. Consider a QLAC at 73. A qualified longevity annuity contract defers some required minimum distributions past 85, protecting against the exact scenario where the retiree outlives the conservative projection.

Pair these with a spending rule: in any year the portfolio drops 15% or more, cut the withdrawal rate from roughly 3% to about 1.5% until it recovers. The math at 67 is generous. The math at 87 is whatever COLA decides it is.

Editor’s note: This article was updated to reflect the confirmed 2026 Social Security COLA of 2.8% and the 2025 COLA of 2.5%, the May 2026 headline CPI reading of 4.2% and Core PCE annual rate of 3.41%, the Federal Reserve’s June 17, 2026 decision to hold the federal funds rate at 3.50% to 3.75%, and current short-term Treasury yields near 3.6%.
