A Single Premium Immediate Annuity is built to do one thing extremely well: maximize what you get for the risk of living a long time. Through mortality pooling, the longer you live, the better a straight-life SPIA performs for you — that's the entire mechanism.
Choosing a payout option is really a decision about whether to work against that mechanism on purpose. Every option beyond straight life means buying a small, embedded death benefit — some might call it a life insurance policy — built directly into a contract otherwise designed to reward you for living, not for dying. That benefit is priced and paid for by your annuity carrier, not by a life insurer, and every dollar it costs comes directly out of the longevity protection the contract was built to maximize.
This article walks through all four ways a SPIA can be structured — straight life, cash refund, installment refund, and life with period certain — what each one actually promises, how they compare against each other with real numbers, and which underlying fear each one is designed to solve. By the end, you'll be able to try the trade-offs yourself with the interactive tool below, before running your own numbers in the full SPIA Income Estimator.
A Quick Disambiguation, Before Anything Else
"Period certain" shows up in two completely different annuity products, and mixing them up leads to a real misunderstanding. A standalone Period Certain Annuity has no life contingency at all — it pays for a fixed number of years and stops at the end of the term, even if you're still alive. That's a different product, covered on our Period Certain Annuities page.
What a SPIA offers instead is Life with Period Certain — lifetime income, plus a minimum guarantee window. If you outlive the period certain, nothing changes; payments simply continue for life. The guarantee only matters if you die before the window closes. That's the fourth option compared below.
The Four Payout Options, Side by Side
To compare these apples-to-apples, every example below uses the same hypothetical: a $250,000 premium for a 70-year-old. These figures are illustrative only — a model to show how the options relate to each other, not a quote. Your actual numbers depend on your age, sex, state, and the carrier you select.
1. Straight Life (Life Only)
Income continues for exactly as long as you're alive, and stops the moment you die — nothing further is paid to anyone. Because the insurer's obligation ends completely at your death, this option directs the largest possible share of your premium toward your own lifetime income, which makes it the highest-paying of the four.
2. Life with Cash Refund
Income continues for life, exactly like straight life. But if you die before your cumulative payments equal your original premium, the insurer pays your beneficiary the unrecovered difference in a single lump sum. You're trading some monthly income for the guarantee that your premium is never simply forfeited.
3. Life with Installment Refund
This works almost identically to cash refund — the insurer still guarantees your full premium is eventually paid out to you or your beneficiary. The difference is delivery: instead of one lump sum, your beneficiary receives the same monthly payment you were receiving, continuing until the original premium has been fully repaid.
Because the insurer holds and continues earning on the unpaid balance longer under this structure, installment refund typically pays a slightly higher starting income than cash refund — often a modest amount more, though the exact gap depends on age and carrier.
4. Life with 10-Year Period Certain
Income continues for life. In addition, the contract guarantees a minimum payment window — commonly 10 years. If you live past that window, absolutely nothing changes; you simply keep receiving payments for life, same as straight life. The guarantee only activates if you die during the window, in which case your beneficiary receives the remaining scheduled payments through the end of that period.
Because this only protects a limited window rather than your full premium, it typically carries the smallest income reduction of the three protected options.
See What Happens at Each Death Year

Cash refund and installment refund don't just differ in how the money arrives — they differ in how it's taxed to your beneficiary, and that difference is worth knowing before you choose.
A cash refund pays out as one lump sum in a single tax year. If a meaningful portion of that lump sum represents taxable earnings rather than a return of your original premium, it can land your beneficiary in a higher tax bracket for that year alone. An installment refund spreads that same taxable portion across every payment your beneficiary receives, reported year by year — which is often easier to plan around.
For a nonqualified SPIA (funded with after-tax savings), only the earnings portion of the refund is taxable; the part that represents your own original premium comes back tax-free. For a qualified SPIA (funded from an IRA, 401(k), or similar pre-tax account), the entire refund is generally taxable as ordinary income to the beneficiary, regardless of which refund option was selected — assuming all contributions were made with pre-tax dollars. Some IRAs contain after-tax contributions as well, which changes this calculation.

What Happens If You Add a Second Life
Every option above can also be structured as a joint-and-survivor contract, continuing income to a spouse after the first death. Stacking a survivor percentage on top of a refund guarantee compounds the cost — the insurer is now pricing two separate risks at once: how long either of two people might live, and the promise to return unrecovered premium on top of that. The result is generally the lowest starting income of any combination on this page.
The mechanics of the survivor-percentage choice itself are covered in Joint and Survivor SPIAs. And before assuming a reduced survivor benefit is the only way to protect a spouse, it's worth understanding the alternative laid out in Joint Survivor SPIA or Separate Life Insurance?
Which Fear Are You Actually Solving For?
Every payout option answers a different underlying concern. Naming yours honestly is a better starting point than comparing dollar amounts alone.
| Your main concern | Option that addresses it |
| Maximizing income; no one depends on this money after I'm gone | Straight Life |
| Dying early and having my beneficiary get nothing back | Cash Refund or Installment Refund |
| Worried a beneficiary might struggle to manage a lump sum responsibly | Installment Refund |
| Want beneficiary liquidity fast, for expenses like final costs | Cash Refund |
| Want a modest floor of protection for a specific window (e.g., until a mortgage is paid off) without paying for full premium return | Life with Period Certain |
The Alternative Worth Knowing About
Every option above is, functionally, a small life insurance benefit — priced and paid for by your annuity carrier. That carrier is in the business of pricing longevity risk, not underwriting life insurance, and the two aren't always priced the same way. For some buyers, it can be more efficient to take the highest straight-life income and separately protect beneficiaries with underwritten life insurance instead of paying an annuity carrier for the same protection.

Frequently Asked Questions
Is "period certain" the same thing as "life with period certain"?
No. A standalone Period Certain Annuity pays for a fixed term and stops when that term ends, even if you're still alive — it has no lifetime guarantee at all. Life with Period Certain, the option compared on this page, pays for life and simply adds a minimum guarantee window at the start of the contract.
Why does installment refund usually pay slightly more than cash refund?
Because the insurer holds and continues earning on the unrecovered balance for longer under an installment structure, rather than releasing it all at once. That advantage is generally passed through as a small increase in your starting monthly income.
Can I change my payout option after the SPIA starts paying?
No. A SPIA is generally an irrevocable contract once the free-look period ends. The payout option, along with the premium and income structure, is locked in at issue.
Is the refund amount taxable to my beneficiary?
Generally, yes, to the extent it represents previously untaxed gain rather than a return of your original premium. For a nonqualified SPIA, only the earnings portion is taxable. For a qualified SPIA, the full refund is typically taxable as ordinary income — if all contributions were made with pre-tax dollars. Some IRAs contain after-tax contributions as well, which changes this calculation. See How a SPIA Is Taxed for the full mechanics.
Does it cost anything to use the SPIA Income Estimator, and is my information safe?
The estimator is free, and it doesn't ask for your name, email, phone number, or any other personal identifying information — you can run it anonymously just to explore the numbers. It's an educational planning estimate only, not a quote, tax opinion, or guarantee of available income; actual insurer quotes depend on your exact date of birth, premium, state, and selected structure.
