The Single Premium Immediate Annuity That Pays a 73-Year-Old $4,800 a Month for Life and Takes Sequence Risk Off the Table

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?

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. The reason is the “mortality credit”: the insurer pools many annuitants and accepts that some will die early, allowing it to pay survivors more than a bond portfolio could. No mutual fund, ETF, or laddered Treasury can replicate that mechanic, because none of them can pool longevity risk.

The rate environment also matters. The 10-year Treasury yields almost 4.5%, the 30-year sits near 5.1%, and the Fed Funds rate has held near 3.75% for five months after 75 basis points of cuts from a 4.5% peak in September 2025. SPIA payouts are priced off long Treasuries, so today’s rates lock in better income than retirees could have secured in 2020 or 2021.

The Math at Three Payout Levels

For a 73-year-old targeting $57,400 of annual income, here is what different vehicles require:

1. 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 the SPIA.
2. 6% yield (covered call funds, REITs, preferred shares): roughly $957,000. Income is higher, dividend growth slows, and principal can drift sideways for years.
3. 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. Payments are taxed as ordinary income, not long-term capital gains. And inflation matters: Core PCE has climbed from about 126 in May 2025 to roughly 129 in March 2026, so a fixed $4,800 will buy less in 2036 than in 2026. Adding an inflation rider sounds appealing until you see the cost: it cuts the initial payout by 30% or more, which rarely makes sense for a retiree past 70 with a roughly 15-year planning horizon.

How to Use a SPIA Without Overdoing It

Three actions are worth taking before writing the check:

1. 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; annuitizing less than 30% rarely moves the income needle.
2. Ladder purchases across ages 70, 75, and 80. Buying one contract today locks in current rates for life. Spreading purchases across three ages diversifies against future rate moves and rising mortality credits at older ages, when payout rates climb sharply.
3. 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 writers should verify quotes against.

With consumer sentiment at 53.3, near recessionary territory, the appeal of trading market exposure for a check that arrives every month for the rest of your life is easy to understand. The SPIA works best as part 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.
