What Is a Single Premium Immediate Annuity (SPIA)?

Some retirees want income right away—without the uncertainty of market fluctuations.

A Single Premium Immediate Annuity (SPIA) is a type of annuity designed to provide a guaranteed income stream that starts within 30 days to one year after purchase. Often described as a personal pension, a SPIA offers predictable payments for life or a set period, depending on how it’s structured.

How Does a SPIA Work?

A SPIA is a contract between you and an insurance company where you provide a lump sum payment in exchange for guaranteed income. Unlike other annuities that accumulate value over time, SPIAs begin distributing payments almost immediately.

Here’s how it works:

You contribute a one-time lump sum to the annuity.
You choose when you want payments to start (typically within 30 days to one year).
The insurance company guarantees regular income payments for life (or for a set period).

Because SPIAs remove market risk, they are ideal for individuals who need immediate, predictable income in retirement.

Key Features and Benefits of a SPIA

SPIAs offer several advantages that make them a valuable retirement income strategy:

Guaranteed Lifetime Income – Payments continue for as long as you live.
No Stock Market Risk – Your payments remain steady, regardless of market conditions.
No Annual Fees – Unlike some annuities, SPIAs typically have no ongoing fees.
Flexible Payout Structures – Choose lifetime income, period-certain payouts, or a combination of both.
Customizable COLA (Cost of Living Adjustment) – You can add an inflation-adjusted increase to your payments.
Joint Income Options – Can be structured to provide income for you and a spouse.
Tax-Advantaged Growth – If purchased in a non-IRA account, only the earnings portion of payments is taxable.

Since SPIAs are designed for income, not growth, they work best as part of a retirement income plan rather than as an investment vehicle.

What Determines a SPIA’s Payout Amount?

Many people assume that interest rates are the biggest factor in determining SPIA payouts, but the primary pricing factor is life expectancy at the time of purchase.

The younger you are, the lower your payments, since they are expected to last longer.
The older you are, the higher your payments, as they are projected to last for a shorter period.

Interest rates do play a role, but life expectancy drives the pricing. This is why SPIAs typically provide higher payouts than other annuity types—they are designed to return both principal and interest over time.

How Is a SPIA Different From Other Annuities?

SPIAs are often compared to other types of annuities, but their immediate payout structure sets them apart:

SPIAs vs. Deferred Annuities: SPIAs begin payments within a year, while deferred annuities allow funds to grow over time before income starts.
SPIAs vs. Fixed Annuities: Fixed annuities grow at a guaranteed rate, while SPIAs are structured for guaranteed income payments rather than accumulation.
SPIAs vs. Pensions & Social Security: A SPIA functions similarly to a pension, but unlike Social Security, you can choose how it’s structured and when payments begin.

Because SPIAs focus solely on income generation, they are not meant for growth or liquidity needs. Once funds are committed, access to the principal is typically not available.

When Should You Consider a SPIA?

A SPIA may be a good fit if you:

Need a guaranteed income stream that starts immediately.
Want protection from market volatility in retirement.
Prefer a simple, transparent income strategy with no ongoing management.
Have other liquid assets available for unexpected expenses.
Want a pension-like income but don’t have access to an employer pension.

SPIAs are not ideal for those who may need access to their lump sum in the future. They work best when combined with other assets that provide flexibility.

Are SPIAs Customizable?

Yes—SPIAs offer several customization options to fit different retirement goals:

Lifetime Income vs. Period Certain: Choose payments for life or for a fixed number of years.
Joint vs. Single Life: Provide income for yourself alone or include a spouse or beneficiary.
Cost of Living Adjustment (COLA): Add an inflation-based increase to payments (though this lowers initial payout amounts).
Payout Frequency: Receive income monthly, quarterly, semi-annually, or annually.
Since SPIAs are contractually guaranteed, all options must be selected at the time of purchase.

Final Thoughts

A Single Premium Immediate Annuity is a straightforward and effective way to generate guaranteed retirement income. By converting a lump sum into a predictable income stream, SPIAs provide stability, security, and peace of mind for those seeking a pension-like solution.

As with any retirement decision, it’s important to consider your personal goals, income needs, and liquidity preferences before purchasing a SPIA. For individuals looking for a simple, worry-free income strategy, a SPIA can be a strong addition to a well-rounded retirement plan.
