Single Premium Immediate Annuity (SPIA)

Most retirees never figure out the income problem. They spend decades building a number — a 401(k) balance, an IRA, a brokerage account — and then face a question no spreadsheet fully answers: how do you turn a lump sum into income you can't outlive without taking on risk you can't afford?

A single premium immediate annuity (SPIA) is the only financial product built specifically to solve that problem. You hand over a lump sum. The insurance company sends you a check every month for as long as you live. The math is straightforward; the decision behind it rarely is.

As an independent agency working across 30+ A-rated carriers, I've run SPIA quotes for clients at every income level and risk tolerance. This page explains how SPIAs work, what drives your monthly payment, and who they actually make sense for — including who they don't.

Key Takeaways

• A SPIA converts a single lump sum into guaranteed lifetime income starting within 30 days of purchase
• Monthly payments depend on your age, gender, guarantee period, and current interest rates — older buyers receive higher payments
• In our May 2026 income annuity survey, a $250,000 SPIA with a 5-year period certain for a 65-year-old male in Ohio topped out near $1,696/month from the leading carrier — roughly double what the 4% rule would produce from the same balance
• SPIAs are irrevocable — once purchased, you cannot access the principal
• Qualified SPIAs (funded from pre-tax retirement accounts) are fully taxable; non-qualified SPIAs (after-tax dollars) are only partially taxable via an exclusion ratio
• Best candidates: retirees with limited guaranteed income who want to eliminate longevity risk from a portion of their portfolio

How a SPIA Works

A SPIA is a contract between you and an insurance company. You make one lump sum payment — the single premium. In exchange, the insurer begins monthly income payments within 30 days, guaranteed for the period or lifetime you selected.

The insurance company calculates your payment using three inputs: your age and gender (which determine life expectancy), the current interest rate environment (which determines how much they earn on your money), and the guarantee period you choose (which affects how much mortality pooling applies to your payment).

Mortality pooling is the key mechanism that makes SPIAs generate more income than you could produce yourself. Policyholders who die earlier than expected effectively subsidize those who live longer. This allows the carrier to pay you more per month than a bond ladder or safe withdrawal strategy would — because they're bearing the longevity risk across a large pool of annuitants, not just your single account.

SPIA Payment Options

Lifetime Income Options

Life Only: The highest monthly payment available, but payments stop completely when you die. Any remaining funds stay with the insurance company. Works for single individuals with no legacy concerns who want to maximize monthly income.

Joint Life: Payments continue until both you and your spouse die. Monthly payments are lower than life-only because the carrier is covering two lifetimes. You can choose 100% continuation for the surviving spouse or reduced payments — 75% or 50% — to get a higher initial benefit.

Period Certain Options

Life with Period Certain: Guarantees payments for your lifetime, but if you die before the period ends (typically 5, 10, or 20 years), payments continue to your beneficiaries for the remainder of that period. This is the most common structure for retirees who want longevity protection without completely forgoing a death benefit.

Fixed Period: Pays for a specific number of years regardless of whether you're alive. Higher monthly payments than lifetime options, but you bear the longevity risk — if you outlive the period, the income stops.

Current SPIA Rates

Interest rates directly determine SPIA payouts — higher rates mean higher monthly checks for the same premium. The current environment has produced the best SPIA income in over a decade, which is directly relevant for retirees evaluating these products now.

Here's a sample from our May 2026 income annuity survey: male, age 65, Ohio, $250,000 premium, 5-year period certain, monthly income payout.

The spread between the highest and lowest carrier in this run is $72/month — that's $864 per year, locked in for life. That gap is why running multiple carriers matters on a SPIA purchase. Rates shift by state, age, and guarantee period, so always compare fresh illustrations before you commit.

Qualified vs. Non-Qualified SPIAs

The tax treatment of your monthly payments depends entirely on where the premium came from.

Qualified SPIAs

Funded with pre-tax dollars — rollovers from IRAs, 401(k)s, or other tax-deferred retirement accounts. Every dollar of monthly income is subject to ordinary income tax, because you haven't paid taxes on that money yet. This is the most common structure for retirees converting retirement savings into income.

Non-Qualified SPIAs

Funded with after-tax dollars from personal savings or taxable accounts. Only the interest portion of each payment is taxable. The principal portion returns to you tax-free, calculated via an exclusion ratio the insurance company provides at issue. For example, on a $250,000 non-qualified SPIA, your contract will specify what percentage of each monthly payment is a tax-free return of principal and what percentage is taxable interest. Consult your CPA on how the exclusion ratio applies to your specific situation.

Who a SPIA Is Best For

SPIAs work for a specific type of retiree. Before I recommend one, I look for a few things: limited guaranteed income outside Social Security, a genuine fear of outliving assets, and enough overall liquidity that the irrevocable nature of the purchase doesn't create a problem.

The strongest use case is a retiree who wants a floor of guaranteed income — Social Security plus a SPIA — that covers essential expenses regardless of what markets do. Layering guaranteed income over variable assets gives the rest of the portfolio room to stay invested longer without the pressure of forced withdrawals in down markets.

SPIAs also work well for retirees who want to simplify. No investment decisions, no portfolio rebalancing, no worry about sequence of returns risk. One check, every month, for life.

Who a SPIA Is NOT For

This is where most agents won't go, so I will. SPIAs are not the right product if:

You need access to your principal. Once the premium is transferred, it's gone. There is no surrender value, no liquidity option, and no changing your mind. If your liquidity reserves are thin, a SPIA isn't the right move until that's addressed.

You have significant inflation concerns with no mitigation plan. A fixed $1,696/month payment today buys less in 10 years. A 3% COLA rider can address this but will reduce your starting payment by roughly 20% — the tradeoff is real and worth modeling before you commit.

You're in poor health with a short life expectancy. Mortality pooling works in your favor if you live long. If you don't, a life-only SPIA represents a transfer of wealth to the insurance company, not income for your heirs. Joint life or period certain options mitigate this, but at the cost of a lower monthly payment.

You want to leave a large inheritance. SPIAs are income products, not estate planning tools. If legacy is a primary objective, whole life or a different annuity structure will serve that goal better.

SPIA vs. Other Retirement Income Strategies

SPIA vs. the 4% Rule

The 4% rule applied to a $250,000 portfolio generates $10,000 per year — $833 per month. The top SPIA quote in our May 2026 survey for the same premium was $1,696/month, more than double the income. The tradeoff: the 4% rule preserves principal access and gives you portfolio growth potential; the SPIA trades both for certainty.

Neither is wrong. The question is which risk — longevity risk or liquidity risk — costs you more.

See our 4% rule calculator to stress-test withdrawal scenarios on your own balance.

SPIA vs. Bond Ladders

A bond ladder generates predictable income and returns principal at maturity. It works well until you outlive the ladder — after which you're out of income. A SPIA solves the longevity problem that a bond ladder can't, at the cost of principal access.

SPIA vs. Fixed Indexed Annuities

A fixed indexed annuity accumulates cash value with index-linked crediting and a floor, then converts to income later. A SPIA skips accumulation entirely and starts income immediately. SPIAs pay more per dollar of premium than FIAs in the income phase because there's no accumulation period or optional benefit costs embedded in the structure.

Inflation Considerations

Standard SPIAs pay a fixed monthly amount. In a 20-year retirement, that fixed payment loses meaningful purchasing power. Two options exist:

Cost-of-Living Adjustment (COLA) riders increase payments annually — typically 1–3%. A 3% COLA rider on a $250,000 SPIA will reduce the initial payment by roughly 20% but catches up in real value after approximately 8–10 years. Worth modeling if you're younger at purchase or expect a long retirement.

Laddering — splitting your SPIA premium across multiple purchases over several years — lets you benefit from potentially higher future rates while building in a form of staggered income growth. Instead of one $500,000 SPIA at 65, you buy a $250,000 SPIA at 65 and another at 70. The 70-year-old SPIA pays more per dollar because your life expectancy is shorter.

Choosing a SPIA Carrier

Two things matter: financial strength and current payout rate. A.M. Best ratings of A or higher indicate carriers with the claims-paying ability to back a 20- or 30-year income commitment. Current payout rate varies monthly with interest rates — the leader changes based on your state, age, and guarantee period, which is why running fresh quotes matters.

In our May 2026 survey, EquiTrust led on raw monthly payout for the quoted Ohio case; Athene, Nationwide, Minnesota Life, and Integrity (W&S) clustered near the top among A+ carriers on period-certain designs. That ranking will shift. Use it as a starting point, not a permanent verdict.

For detailed carrier analysis and financial strength comparisons, see our best SPIA companies review.

If you're ready to compare what different carriers would pay for your specific premium and age, the most useful next step is running illustrations side by side.

SPIA quotes assume stated premium, age, and guarantee period—half a point on mortality assumptions shifts monthly checks. While you pressure-test immediate income, also compare MYGA rates on any deferred tranche you might ladder alongside SPIA funding.
