What Is a SPIA? Income That Starts Now

What does SPIA stand for, and how does one actually work?

Each word in the name does a job. Single premium means you fund it once, with one deposit, rather than a series of payments. Immediate means income begins right away by annuity standards, within about a year of the deposit rather than after a long growth phase. Annuity means the deal itself: an insurance contract that trades your money for a promise of scheduled income, explained from the ground up in our guide to what an annuity is.

The mechanism that makes lifetime income possible is pooling. Among thousands of SPIA owners, some collect payments for a few years and some for several decades. The insurer prices the promise across the whole group, the same way it prices any other insurance. That is why a SPIA can commit to paying you at 95 without knowing whether you will get there: someone in the pool will not, and the pool pays for those who do.

People sometimes call a SPIA a private pension you buy for yourself, and the comparison is fair. If your job never came with a pension, a SPIA is the closest retail product to one, a point we unpack in our post on annuity vs pension.

Any guarantee is backed by the claims-paying ability of the issuing insurer; it is not FDIC-insured or bank-guaranteed.

How soon does SPIA income start?

By definition, within twelve months of your deposit. In practice, most buyers choose monthly payments starting one month after the premium is paid. You pick the frequency, monthly, quarterly, or annual, and the start date within that first-year window, and the insurer takes it from there. There is no accumulation phase, no crediting formula to track, and nothing to manage afterward. For many retirees that simplicity is the main attraction.

If you want income that starts years from now instead, that is a different tool: a deferred income annuity, or DIA. Its retirement-account variety, the QLAC, can push income as late as age 85 and is limited to $210,000 of premium in 2026 under federal law. The full lineup, and how a SPIA differs from fixed and fixed-indexed contracts, is laid out in our types of annuities guide.

What payout options can you choose, and what does each cost?

The single most important decision on a SPIA application is not the insurer or the amount. It is the payout option, because it controls what happens while you live and what happens when you die. Every layer of protection you add for a spouse or your heirs is paid for with a smaller check while you are alive. That is not a trick; it is arithmetic.

All payout guarantees are subject to the claims-paying ability of the issuing insurer and are not FDIC-insured. Option names and availability vary by contract and state.

How the paycheck itself is engineered, and how these options fit inside a broader income floor alongside Social Security, is the subject of our guide to guaranteed lifetime income.

What decides how much a SPIA pays?

Four inputs do most of the work. Your age, because the older you are at purchase, the fewer expected payments the insurer must fund and the larger each one can be. Your payout option, for the reasons in the table above. The interest rate environment on the day you buy, because the insurer invests your premium mostly in bonds, and what those bonds earn flows into pricing. And the premium itself, since payments scale with the amount you convert.

This is why no honest article can tell you what a SPIA pays. Quotes differ from insurer to insurer, change with rates, and depend on facts about you. The useful habit is to collect several written quotes for the identical option on the same day, so you are comparing like with like. For a plain-English walkthrough of the moving parts, using clearly labeled illustrative ranges rather than quotes, see our post on how much a $100,000 annuity pays.

How is SPIA income taxed?

It depends on the money you fund it with. Buy a SPIA with pre-tax retirement money, such as IRA or 401(k) dollars, and every payment is generally taxed as ordinary income, because none of it has been taxed yet.

Fund it with after-tax savings and the treatment is friendlier. Growth inside an annuity is tax-deferred, never tax-free, but if you annuitize a contract you funded with after-tax dollars, part of each payment returns your own principal untaxed until your basis is used up. The IRS calls the math behind this the exclusion ratio. Once your basis is recovered, the full payment becomes taxable. Withdrawals or income before age 59½ may also face a 10% federal penalty on the taxable portion. How annuity income stacks with Social Security taxation and required minimum distributions is covered in our guide to the retirement tax picture. Consult a licensed tax advisor about your own numbers before you buy.

When is a SPIA the wrong fit?

Often enough that it deserves its own section. A SPIA is irreversible by design: once you annuitize, the lump sum is gone as a pile of accessible savings, and no later regret brings it back. If there is any real chance you will need that money for a roof, a health event, or a family emergency, a SPIA is the wrong home for it. Keep your emergency fund and your flexible savings out of any annuity.

It is also the wrong tool when the job is already done. If Social Security plus a pension covers your essential expenses, more guaranteed income mostly buys you less flexibility. If leaving the largest possible estate is your first goal, converting savings into lifetime income works directly against it. And a level payment that feels comfortable at 65 buys noticeably less at 85, because most SPIAs make no adjustment for inflation. The honest full list of people who should walk away is in who should not buy an annuity, and a question-by-question self-check lives at is an annuity right for me.

One more honest note. Because the promise runs for decades, the promiser matters. Check the issuing insurer's financial strength ratings from the major rating agencies before you sign, and know how your state guaranty association backstop works and where its limits sit. We wrote up that whole subject in what happens if an annuity company fails.
