Retirement Income Annuities: Do They Belong in Your Withdrawal Plan?

Annuities have a reputation problem, and most of it is earned. Variable annuities with layered fees and surrender charges deserve the suspicion they get. But a plain single premium immediate annuity, or SPIA, is a different product entirely: you hand over a lump sum and the insurer sends you a monthly check for the rest of your life. That is a trade worth understanding before you dismiss the whole category.

The confusion comes from lumping everything together. A deferred variable annuity sold to a 40-year-old as an "investment" is a very different animal from a SPIA bought at 68 to cover the electric bill. If you are evaluating annuities for retirement income, you are almost certainly in the second conversation.

The three annuities worth understanding

Most of the annuity products sold are complicated on purpose. The three that show up in sensible retirement plans are simple, which is the tell that they are worth your time.

• Single premium immediate annuity (SPIA): You pay a lump sum today and start receiving income within a year. The payment is fixed, or it can rise slightly with an inflation adjustment, and it lasts for a set period or for life.
• Multi-year guaranteed annuity (MYGA): Closer to a CD than an income stream. You deposit money, it grows at a fixed rate for a set number of years, and you take it back at the end. Useful for a cash buffer, not lifetime income.
• Deferred income annuity (DIA): You pay now and the payments start later, often at 80 or 85. This is longevity insurance in its purest form and is usually bought in smaller amounts.

The high-fee variable and indexed products are not on this list because they solve a sales problem, not a retirement problem. If a product comes with a thick illustration and a rider for everything, the value is usually buried under the cost.

What an income annuity actually does for a plan

The honest case for a SPIA is that it converts a lump sum into a paycheck, and a paycheck is psychologically and mathematically different from a portfolio. A couple who needs $2,400 a month to cover housing, utilities, and groceries can either draw that from investments and hope the market cooperates, or buy a stream that pays it regardless of what stocks do.

The trade is real and worth stating plainly. You give up liquidity and control of the principal. If you need a large, unexpected withdrawal later, the money is gone. Most plain SPIAs also do not keep up with inflation unless you pay extra for an adjustment, which lowers the starting payment. And a joint-life annuity can leave little or nothing for heirs unless you add a period-certain or refund feature, which again lowers the payout.

What you gain is sequence-of-returns protection. Retirees who start withdrawals in a bad market do lasting damage because they are selling assets at the bottom. A fixed income floor removes those core bills from that risk. That is the entire argument, and it is a good one for the right share of your savings.

Annuity versus portfolio withdrawals, worked through

Take a 66-year-old couple with $900,000 saved and $42,000 a year in combined Social Security. They decide they need $72,000 a year to live well, so the gap is $30,000 a year, or $2,500 a month. They could draw that gap from the portfolio, which at a 4% withdrawal rate needs about $750,000 to fund. Or they could use roughly $300,000 of the portfolio to buy a joint-life SPIA paying around $2,000 to $2,500 a month, depending on age, rates, and contract terms, and invest the remaining $600,000 for flexibility.

Neither path is obviously better. The annuity path shrinks the money they control and locks in today's rates, but it also removes most of the sequence-risk exposure from their essential bills. The all-portfolio path keeps full control and inflation protection, but leaves them selling assets in every downturn. The right answer usually lands somewhere in the middle, with an income floor that covers true necessities and a portfolio for everything else.

This is exactly the kind of comparison worth running with your own numbers. RetireFree's How Much to Retire planner builds the income gap from your spending and guaranteed sources like Social Security, and the Retirement Withdrawal Calculator shows the spending range a given portfolio can support without the annuity.

Where annuity plans usually go wrong

The mistakes are predictable, and most of them come from buying too much or buying the wrong product. First, annuitizing money you might need for long-term care or an emergency is how people end up illiquid exactly when they cannot afford to be. Second, buying an income stream years before you need it gives up growth for no benefit, since the product's real value is protecting income in the years you are most at risk of running out. Third, ignoring inflation on a 30-year stream quietly halves your purchasing power.

The cleanest framing is to ask what specific expense the annuity is covering and whether losing access to the principal is acceptable for that expense. Covering groceries and property taxes is a good reason. Funding a travel hobby that might stop next year is not. Keep the annuity to a slice of the plan, and keep the portfolio doing the flexible, growth-oriented work.

If the whole idea of a fixed income floor appeals to you, look at the underlying concept before the product. A pension or maximizing delayed Social Security does the same job, often at a better rate. The Social Security Calculator can show how much of your floor you can build just by choosing when to claim.

Bottom line

A plain income annuity is a tool with a narrow, real job: turning a slice of savings into a check that lasts as long as you do. It is not an investment, and it is not a replacement for a diversified portfolio. Buy it only for essential bills, only with money you can afford to lock up, and only after you have compared it against the income you can build from Social Security and your portfolio alone. Understood that way, it is a legitimate piece of a retirement plan. Understood any other way, it is how people end up paying for complexity they never needed.

Frequently asked questions

Is a single premium immediate annuity a good idea?

It can be, for the right share of savings. A SPIA makes sense when it covers essential, predictable bills and you accept giving up access to the principal. It is a poor fit for money you might need for long-term care, emergencies, or heirs. The decision depends on your spending floor, your health, and the rates available when you buy.

What is the difference between a SPIA and a deferred income annuity?

A SPIA starts paying within a year of purchase. A deferred income annuity is bought now but payments begin later, often at 80 or 85, and is used as pure longevity insurance. Because payments start later and some buyers never collect, a deferred income annuity typically offers a larger eventual payout for the same premium.

Do annuities protect against inflation?

Only if you pay extra for an inflation or cost-of-living adjustment, which lowers the starting payment. A plain fixed SPIA pays the same nominal amount for life, so its purchasing power falls over time. Many planners prefer to cover essentials with a fixed annuity and keep the rest of the portfolio invested for growth that outpaces inflation.
