An Immediate Annuity (also known as a 'Single-Premium Immediate Annuity' or 'SPIA') is a contract you make with an insurance company that converts a single lump sum of cash into a guaranteed stream of income. Think of it as creating your own personal pension. You hand over your capital, and in return, the insurer promises to send you a regular check, typically starting within a month or a year. These payments can last for a specific period or for the rest of your life. The person receiving the payments is called the annuitant. This is in direct contrast to a deferred annuity, where your money grows for a period of years before you start taking payments. An immediate annuity is not an investment in the traditional sense; it's an insurance product designed to protect you from longevity risk—the danger of outliving your savings.
The mechanics are straightforward. You decide how much money you want to commit, and the insurance company calculates the size of your regular payment. This calculation is a bit like a secret recipe, but the main ingredients are:
Once you sign the contract and hand over your money—your principal—the decision is almost always irreversible. That capital is gone, exchanged for the promise of future income.
You have several choices for how you'll receive your money, each with a significant trade-off between the payment amount and the level of security.
This option provides the highest possible regular payment. The catch? The payments last only for your lifetime. If you purchase a life-only annuity and are hit by the proverbial bus a month later, the insurance company keeps the remainder of your principal. All payments cease.
This adds a safety net. A “Life with 10-Year Period Certain” annuity pays you for life. However, if you die within the first 10 years, your named beneficiary will continue to receive payments until that 10-year period is over. This guarantee results in a smaller monthly payment compared to a life-only option.
This is a popular choice for couples. It provides income for as long as either you or your spouse (or other designated person) is alive. When the first person dies, the survivor typically continues to receive payments, often at a reduced rate (e.g., 50% or 75% of the original amount). Naturally, because the insurer is on the hook for two lifetimes, this option provides the lowest initial payment.
A value investor approaches annuities with extreme caution. We prize flexibility, control over our capital, and buying assets for less than their intrinsic value. The immediate annuity structure challenges all three of these principles.
An immediate annuity is an insurance product, not a wealth-building investment. Its sole purpose is to transfer the risk of outliving your money to an insurance company, for a price. For a value-oriented investor, it rarely makes sense to annuitize a large portion of one's nest egg. However, using a small portion to buy an immediate annuity to cover basic, non-discretionary living expenses could be a reasonable defensive move in retirement. This can create a psychological “floor,” freeing you to invest the rest of your capital for long-term growth with more confidence. Before buying, always remember you are trading a large sum of flexible capital for a smaller, rigid stream of income.
