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 cover only about $24,400 per year after Social Security. 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 annual 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 comfortably above the critical 2% threshold this plan requires. The Social Security Administration puts the decade average near 3.1%. On October 14, 2026, the SSA officially announced the 2027 COLA at 3.6%, the largest benefit increase since 2023. The figure landed exactly in line with the 3.5% to 3.6% range that Social Security experts had projected. For this retiree, that confirmation 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 captures the responsible tail of that distribution. 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 trades near 5.2% and the 30-year sits around 5.5%, both meaningfully higher than they were just a year ago, meaning a laddered Treasury sleeve alone generates more than enough yield on a modest slice of capital. To produce the full $24,400 at 3.5%, the math points to roughly $697,000 of dedicated capital, leaving the rest of the $920,000 free to grow and 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 pace 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 income gap on a much smaller capital base, about $244,000 at a 10% distribution rate. The risk is principal erosion. A retiree drawing a 10% distribution while watching underlying NAV slide 3% to 5% annually is spending the asset itself, not living off its earnings.

The COLA Variable That Breaks or Makes the Plan

This is where the headline condition matters most. September 2026 CPI came in at 3.7% year over year, up from 3.4% in August and hotter than the 3.6% consensus forecast. Gasoline prices rose 9.1% in September, accounting for more than half the monthly increase. Core CPI, which strips out food and energy, rose 2.6% annually, accelerating from 2.4% in August and topping economist estimates of 2.5%. Energy costs remain the primary inflation driver, with the energy index up 5.2% for the month.

The Federal Reserve raised its target rate by 25 basis points to a range of 3.75% to 4.00% at its September 16, 2026 meeting, the first hike in three years, with all participants voting in favor. The next rate decision is scheduled for October 28. After the hot September CPI print, the odds of an additional hike at that meeting rose sharply in bond markets, a development that affects the yield environment retirees count on for income. If the Fed hikes again in October or December, short-term Treasury yields would move higher still, benefiting the cash-reserve tier of this plan.

Run two scenarios with the same starting Social Security check. If COLA averages 2.5% a year, the monthly benefit grows to roughly $66,000 annually by age 95. If COLA averages only 1.8%, it grows to about $54,000, a $12,000 shortfall the portfolio must cover each year. 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. The now-confirmed 3.6% COLA for 2027 is consistent with the optimistic scenario, and the 3-in-a-row run of adjustments above 2.5% suggests this retiree’s purchasing power is, for now, holding its own.

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. Three-month T-bills now yield roughly 4.2%, paying 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 5.5%, 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.

Editor’s note: This article was updated to reflect the official SSA announcement of a 3.6% Social Security COLA for 2027 (the largest increase since 2023), current 10-year Treasury yields near 5.2% and 30-year yields near 5.5%, the September 2026 CPI reading of 3.7% year over year with core CPI at 2.6%, and the Federal Reserve’s unanimous 25-basis-point rate hike to 3.75% to 4.00% at the September 16, 2026 meeting. The next Fed decision is October 28, with the October 28 meeting odds updated to reflect post-CPI market pricing. Short-term T-bill yields are updated to approximately 4.2% for the 3-month bill.
