A $350,000 Annuity Guarantees $2,200 a Month for Life, but Here Is What Retirees Give Up

The pitch is simple. Hand an insurance company $350,000 at age 70, and starting next month a check for $2,200 arrives every month for as long as you live. On a $26,400 annual payout against a $350,000 premium, that works out to roughly a 7.5% payout rate, which sounds spectacular next to the 10-year Treasury at 4.54%.

Here is the catch that rarely makes it into the marketing material: that 7.5% figure blends interest, return of your own principal, and mortality credits (the pooled money left behind by annuitants who die earlier than expected). Once you sign, the $350,000 stops being yours.

A single premium immediate annuity, or SPIA, is one of the most common products pitched to retirees sitting on a rollover IRA or a lump-sum pension buyout. Anxiety drives the demand. Schwab’s 2025 participant survey found the retirement “magic number” Americans think they need is $1.6 million, and 57% named inflation as their top retirement obstacle. Guaranteed income can calm that anxiety in a single transaction.

The Trade-Off That Matters Most

Focus on liquidity, because everything else flows from it. A plain single-life SPIA is irrevocable. If a spouse gets a cancer diagnosis in year three, you cannot claw the $350,000 back to pay for treatment. If you die in year four, the insurer keeps the remaining balance and heirs receive nothing.

Compare that with a self-managed drawdown. At today’s 4.5% 10-year Treasury yield, $350,000 in Treasuries alone throws off roughly $17,890 a year in interest without touching principal. Add a balanced equity allocation and a disciplined 4% to 5% withdrawal, and a 70-year-old is pulling $14,000 to $17,500 annually with a strong chance of leaving the original $350,000 (or more) to heirs.

The SPIA wins on cash flow: $26,400 versus roughly $15,000 to $17,500. The self-managed path wins on flexibility and legacy.

Inflation Is the Second Big Cost

Core PCE, the Fed’s preferred inflation gauge, sits at the 90th percentile of its 12-month range. A level $2,200 check that feels generous at 70 buys noticeably less at 80 and materially less at 90. Social Security at least adjusts. The 2026 COLA came in at 2.8%. A plain SPIA does not.

Who Should Actually Sign

Annuitization makes sense for a narrower group than the pitch suggests:

1. Longevity in the family. If your parents lived into their mid-90s, mortality credits swing in your favor and the insurer effectively subsidizes your later years.
2. A gap between guaranteed income and essential expenses. The average U.S. household spent $78,535 in 2024. If Social Security covers the first $30,000 of that, a SPIA can plug the essentials gap.
3. Genuine fear of sequence-of-returns risk. A retiree who will panic-sell in the next bear market is often better off with a guaranteed check than a brokerage statement.

Two Middle-Ground Structures Worth Considering

Partial annuitization. Annuitize only a slice, and keep the rest invested. Our example retiree could convert $150,000 into roughly $940 a month of floor income and invest the remaining $200,000 for growth, liquidity, and heirs. You buy peace of mind without surrendering the whole nest egg.

Inflation-adjusted or cash-refund riders. A rising payout option starts lower (perhaps $1,700 instead of $2,200) but grows 2% to 3% annually, blunting the purchasing-power problem. A cash-refund or period-certain rider ensures heirs receive at least the unpaid balance if you die early.

Before signing anything, get quotes from at least three or four highly rated insurers. Payouts on identical $350,000 premiums routinely vary between carriers, and that gap compounds for the rest of your life.

What to Do This Week

If you’re facing the annuity question, here are two concrete steps to consider. First, price a competing self-managed plan. Model $350,000 growing at 5% while you withdraw $22,000 a year, and see how long it lasts and what remains at age 90. Second, if you still want guaranteed income, request quotes for a partial annuitization with a cash-refund rider rather than a plain single-life SPIA.
