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. Annual spending totals $58,000, which means the portfolio needs to generate only about $24,400 per year to close the gap. That works out to a withdrawal rate of roughly 3%, a figure well within the range most retirement planners consider sustainable over the long run.

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 critical 2% threshold this plan requires. The decade average sits near 3.1% according to the Social Security Administration. Early 2027 COLA estimates from the Senior Citizens League and AARP currently cluster around 3.6% to 3.8%, down from spring highs of 4.2% to 4.7% as headline inflation has moderated, though the official figure will not be announced until October. 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 absorb a drawdown.

The $24,400 Yield Math at Three Risk Levels

The portfolio only has to cover the gap between spending and Social Security income. 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 now trades near 4.7% and the 30-year sits around 5.25%, 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 is real: 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, though, 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 itself, not living off it.

The COLA Variable That Breaks or Makes the Plan

This is where the headline condition matters most. Headline CPI rose 3.4% year over year in July 2026, down from 3.5% in June and well below the 4.2% peak recorded in May. The moderation reflects easing energy prices, though energy costs remain up nearly 15% from a year ago. Core CPI, which excludes food and energy, rose 2.5% annually in July, still above the Fed’s 2% target but trending lower. The Fed voted 9-3 to hold its upper bound at 3.75% on July 29, 2026, with a divided committee weighing persistent inflation against signs of slowing economic momentum.

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 materializes. Given that both the 2025 and 2026 COLAs came in above 2.5% and current 2027 estimates point to a 3.6% to 3.8% increase, the optimistic scenario is more consistent with recent history, even as the pace of inflation has cooled from its spring peak.

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 in the upper 3% range pay the retiree to wait while keeping the buffer fully 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, functioning as longevity insurance for the tail past 90. With the 30-year yield near 5.25%, annuity pricing remains favorable relative to the low-rate years of the prior decade.
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.
