A 73-year-old single retiree with $1.4 million in savings faces a question that the 4% rule does not fully solve: how do you guarantee enough monthly income to cover essentials for life without depending on strong market returns?
One option many retirees overlook is a Single Premium Immediate Annuity, or SPIA. At current rates, a 73-year-old who puts $700,000 into a single-life SPIA from an A+ rated insurer can generate roughly $4,783 per month, or about $57,400 annually. That works out to an 8.2% annualized payout rate. Add a typical $2,800 monthly Social Security benefit and the retiree clears about $7,600 per month in guaranteed lifetime income, while leaving another $700,000 liquid for emergencies, travel, gifts, or legacy planning. Rather than depending entirely on market performance, the retiree creates a private pension and transfers part of the longevity risk to the insurer.
Why the Payout Beats the 4% Rule
Apply the 4% rule to $700,000 and you get $28,000 per year. The SPIA more than doubles that figure. The reason is what actuaries call the “mortality credit”: the insurer pools many annuitants and accepts that some will die early, allowing it to pay survivors more than any bond portfolio could. No mutual fund, ETF, or laddered Treasury can replicate that mechanic, because none of them can pool longevity risk across thousands of policyholders.
The rate environment also reinforces the case. The 10-year Treasury yields around 4.6%, the 30-year sits near 5.1%, and the Fed has held its target range at 3.5% to 3.75% since completing 75 basis points of cuts from a 4.5% peak in September 2025. SPIA payouts are priced off long Treasuries, so today’s yield levels lock in better income than retirees could have secured during the near-zero era of 2020 or 2021. It is worth noting that the June 2026 FOMC meeting, the first under new Fed Chair Kevin Warsh, removed the Fed’s previous easing bias and signaled that rate hikes remain a live possibility later in 2026, which means SPIA shoppers who delay are not guaranteed to benefit from an improving rate environment.
The Math at Three Payout Levels
For a 73-year-old targeting $57,400 of annual income, here is what different vehicles require:
- 3.5% yield (dividend growth ETFs, broad equity income): roughly $1.64 million of capital. Principal stays intact and likely grows, but the capital requirement is more than double that of the SPIA approach.
- 6% yield (covered call funds, REITs, preferred shares): roughly $957,000. Income is higher than a plain equity portfolio, dividend growth slows, and principal can drift sideways for extended stretches.
- 8.2% SPIA payout: $700,000, with the trade-off that the principal is gone the day the contract is signed.
What You Give Up
The SPIA is irrevocable. There is no surrender value, no inheritance from that $700,000, and no liquidity if a roof, a medical bill, or a grandchild’s tuition shows up unexpectedly. Payments are also taxed as ordinary income rather than at the lower long-term capital gains rate. And inflation is a real concern: Core PCE climbed from about 126 in May 2025 to roughly 129 in March 2026, meaning a fixed $4,800 check will purchase measurably less in 2036 than it does today.
Adding an inflation rider sounds like the obvious fix, but the economics rarely work for retirees past 70. A cost-of-living adjustment typically cuts the initial payout by 30% or more, which is a significant sacrifice given a roughly 15-year planning horizon. Most financial planners argue the better move is to keep that initial payout at its maximum and hold a separate inflation buffer in the liquid portion of the portfolio.
How to Use a SPIA Without Overdoing It
Three actions are worth taking before writing the check:
- Cap the SPIA at 30% to 50% of the portfolio. Allocating $700,000 of a $1.4 million portfolio fits cleanly inside this band. Annuitizing 100% removes all flexibility, while annuitizing less than 30% rarely moves the income needle by enough to justify the trade-off.
- Ladder purchases across ages 70, 75, and 80. Buying one contract today locks in current rates for life. Spreading purchases across three age milestones diversifies against future rate moves and captures rising mortality credits at older ages, when payout rates climb sharply.
- Stick to A+ or AA-rated carriers. State guaranty associations cap coverage, often around $250,000 per insurer, so a $700,000 contract concentrates credit risk in one balance sheet. New York Life, MassMutual, and Pacific Life are among the carriers worth including in any quote comparison.
Consumer sentiment hit 54.4 in the University of Michigan’s preliminary July 2026 reading, recovering from May’s all-time low of 44.8 but still running 12% below where it stood a year ago. In that environment, the appeal of trading market exposure for a guaranteed monthly check is straightforward to understand. The SPIA works best as one component of a broader plan. For a 73-year-old who wants to take sequence-of-returns risk off the table on the income she actually needs, it is one of the few tools that can do the job reliably.
Editor’s note: This update refreshed the 10-year Treasury yield from “almost 4.5%” to approximately 4.6% based on mid-July 2026 market data, updated the University of Michigan Consumer Sentiment reading from 53.3 to 54.4 (the preliminary July 2026 figure), and added context on the Fed’s hawkish policy shift under new Chair Kevin Warsh at the June 2026 FOMC meeting.
