Immediate Annuities: Turn a Lump Sum Into Guaranteed Income for Life 

Here’s a scenario that lands on our conference table all the time. A pension plan offers a choice: take $550,000 as a lump sum right up front, or take $2,800 a month for life. Which one do you take? 

Run the simple math with me. Dollar for dollar, with no growth at all, $2,800 a month works out to about 16 years before you’d run through that $550,000. Live longer than that, and the monthly check was the better deal. Don’t, and the lump sum was. That’s the entire tension of retirement income in one decision, and it’s exactly the problem an immediate annuity exists to solve. 

An immediate annuity is the reverse of that pension decision: instead of turning a monthly check into a lump sum, you turn a lump sum into a monthly check. You give an insurance company a single deposit, and in exchange, they start paying you guaranteed income right away, typically within a year, often the very next month, for the rest of your life if you choose. It’s the original annuity. It’s the one your grandparents used. And in the right situation, it’s still one of the most powerful income tools in existence. 

But, and we’re going to be very honest with you in this article, because that’s the job, it is not the tool we reach for most often in our office, and you deserve to know why before you sign anything. Let’s walk through how immediate annuities work, how the payments are calculated, the payout choices that matter enormously, and when this tool genuinely wins. (For the full landscape of annuity types, our complete guide to how annuities work [LINK] is the place to start.) 

How Does an Immediate Annuity Work? 

The mechanics are beautifully simple, which is part of the appeal. 

1. You make a one-time deposit. Say $300,000. This is why the most common version is called a single premium immediate annuity, or SPIA. We’ve got a full deep-dive on how SPIAs work [LINK]

2. Payments begin almost immediately. No accumulation phase, no waiting years for income. You’re buying a paycheck that starts now. 

3. The checks keep coming, for life, for a set period, or both, depending on the payout option you choose. 

Think of it as privatizing your own pension. Most of you weren’t blessed with a pension. You’ve got a 401(k), a 403(b), a TSP. A pile of money instead of a paycheck. An immediate annuity converts a slice of that pile back into the thing retirees actually miss most: a deposit that shows up every month, regardless of what the market does. Some people are perfectly comfortable drawing down a lump sum over the year; others really need to simulate having a paycheck like they were used to for 30 or 40 years before retirement. If you’re in that second group, this product speaks your language. 

How Are Immediate Annuity Payments Calculated? 

The insurance company sets your monthly payment based on four main inputs: 

Your age. The older you are when payments begin, the higher the monthly check. The insurer expects to make fewer payments. 

Your payout choice. Life-only pays the most per month; adding guarantees for your spouse or heirs lowers the check (more on this next, because it’s the decision that matters most). 

Interest rates. Immediate annuity payouts follow the broader rate environment, and rates in 2026 remain near multi-year highs, meaning the same deposit buys a meaningfully bigger paycheck today than it did in the 1%-rate era. We track what’s driving that in our guide to annuity rates in 2026 [LINK]

Your deposit. Straightforward. More premium, more income. 

One thing worth knowing: a portion of each payment from a non-qualified immediate annuity is treated as a tax-free return of your own principal, with only the earnings portion taxed. Inside an IRA, payments are taxed as ordinary income like any other distribution. 

Single Life vs. Joint Life vs. Period Certain: The Decision That Matters Most 

Folks, this is the part of the contract where families get protected, or exposed. Slow down here. 

Life only (single life) 

The insurance company pays you the highest possible monthly check for as long as you live, and payments stop at your death, whether that’s 40 years from now or 4. This is the version that created the old fear: “if I die early, the insurance company keeps my money.” With life-only, that’s genuinely the deal. Highest income, zero legacy. 

Life with period certain 

Payments for life, but with a guaranteed minimum window, say, 10 or 20 years. If you pass away in year 6 of a 10-year certain contract, your beneficiary receives the remaining 4 years of payments. A modestly smaller check in exchange for knowing the money doesn’t vanish. 

Joint and survivor 

Payments continue for as long as either spouse is alive. The check is smaller than a single-life payout, but for married couples this is usually the conversation that matters most. The same reason survivor strategy drives Social Security decisions. Remember: when one spouse passes, the household keeps the higher of the two Social Security benefits, but it loses the lower one. A joint immediate annuity is one way to make sure the surviving spouse’s income floor doesn’t crack right when everything else is falling apart. 

Cash refund / installment refund 

If you pass before receiving back your full deposit, the remainder goes to your beneficiaries. Popular for exactly the reason you’d think. 

There is no universally right choice. There’s a right choice for your longevity picture, your spouse, and your legacy goals. That family-history-of-longevity question from the pension scenario? It applies here with full force. 

When Does an Immediate Annuity Actually Make Sense? 

In our experience, the immediate annuity earns its keep in a few specific situations: 

You’re replacing a pension. You took the lump sum buyout (or you’re deciding whether to), and you miss the check. An immediate annuity can rebuild it, sometimes at a better payout than the pension offered, sometimes not. That’s a math problem we run for people regularly, and it’s the heart of our comparison of annuities vs. pensions for retirement income. [LINK]

A lump sum just landed and income is the need. A business sale, an inheritance, a severance. We had a couple come in at 58 who’d sold their business for a million dollars and needed $10,000 a month to retire well. Their pension covered $4,000, leaving a $6,000 monthly gap. Even with a million in the bank, a gap like that creates real anxiety, because a lump sum you’re draining feels finite in a way a paycheck never does. Converting part of a windfall into guaranteed monthly income is precisely the job this category of product was built for. (We solved that couple’s gap with a bucketing plan.

You want maximum guaranteed income per dollar, right now, and simplicity above all. No caps, no crediting methods, no moving parts. A check. 

The Honest Trade-Offs (and What We Often Use Instead) 

Now for the straight talk, because as fiduciaries we don’t get to skip this section. 

The classic immediate annuity requires you to hand over a lump sum of money to an insurance company. Irrevocably, in most cases, with the arrangement working best if you outlive the payments. You give up control of the principal. You give up liquidity. If an emergency hits in year three, that money is not sitting there waiting for you. And unless you add inflation features (which shrink the starting check), that $2,800 a month buys less every year for the rest of your life. 

That loss of control is exactly why, in our office, the annuities we utilize most often are deferred fixed index annuities instead. Contracts where you still own your principal, you can still access it within the contract’s terms, and income can be turned on through withdrawals or an income rider rather than by permanently surrendering the money. You get the pension-style predictability for your non-discretionary expenses without handing over the keys. We break down that whole approach in our guides to how fixed index annuities work [LINK] and how deferred annuities work and when to use one [LINK]

So is the immediate annuity obsolete? Not at all. When someone needs maximum income starting now, has other liquid assets covering emergencies and legacy, and values simplicity, a SPIA can beat the alternatives on pure payout. The point is that it should win a head-to-head comparison, not be the only option you were ever shown. 

The Next Step: Run Your Numbers Before You Sign Anything 

Here’s the bottom line. An immediate annuity answers one question extremely well: how do I turn this lump sum into the largest guaranteed paycheck available, starting today? Whether that’s the right question for you depends on your income gap, your health and longevity picture, your spouse, and what the rest of your buckets are doing. 

So before you convert a single dollar irrevocably, let’s run your numbers side by side: the immediate annuity payout, the deferred alternative, and the do-nothing scenario, all inside a real income plan with taxes and inflation included. It’s complimentary, there’s no obligation, and you’re leaving the checkbook at home. Call 800-653-8404 and tell us you want an income comparison on a lump sum, because a decision you can’t undo deserves math you can trust.
