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 increase through future cost-of-living adjustments over the next 28 years. Even small differences in inflation and COLA growth can compound dramatically over decades, determining whether the retiree maintains purchasing power or gradually falls behind rising costs. What looks stable today can become far more delicate once inflation enters the equation like a raccoon with a calculator and no respect for spreadsheets.

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, 25% of reaching 93, and 10% 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 is about 4.5% and the 30-year is roughly 5%, which means a laddered Treasury sleeve alone produces more than enough on a small slice of capital. To generate the full $24,400 at 3.5%, the math is $24,400 divided by 0.035, or about $697,000 of capital. The rest 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%, $24,400 divided by 0.06 requires about $407,000 of dedicated income capital. That frees up more than half the portfolio for growth, but distributions in this tier rarely keep up with inflation, and covered-call funds give up the upside that compounds a 28-year plan.

Aggressive tier, 8% to 14%. Business development companies, mortgage REITs, and leveraged option-income funds can throw off the gap on a much smaller base. At 10%, $24,400 divided by 0.10 requires just $244,000. The risk is principal erosion. A retiree who funds the gap from a 10% distribution and watches the 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. CPI is running roughly 4% above year-ago levels, the kind of inflation environment that supports a healthy COLA. Core PCE at 129.28 sits modestly above the Fed’s 2% target, and the Fed has held the upper bound at 3.75% since December 11, 2025.

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 gap 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 shows up.

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 2027 bear market never forces a sale at the bottom. Short Treasury yields near 3.7% pay the retiree to wait.
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 is longevity insurance for the tail past 90. Lock in pricing while the 30-year yield is still above 5%.
3. Consider a QLAC at 73. A qualified longevity annuity contract defers some required minimum distributions past 85, which protects 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.
