Income Annuities, Explained in Plain English

Of the three annuity types on this site, an income annuity is the one built around a single purpose: converting a portion of your savings into a guaranteed stream of payments you cannot outlive, regardless of how long you live or what the market does.

How an income annuity works

You give the insurance company a lump sum (or, with a deferred income annuity, a lump sum now for income that starts later). In exchange, the company guarantees to pay you a set amount on a set schedule, often monthly, for either a set period or for the rest of your life, and in many cases for the life of a spouse as well (a "joint life" option).

There are two common structures:

• Immediate income annuity (SPIA): you hand over a lump sum and payments start right away, typically within 30 days to a year.
• Deferred income annuity (DIA): you hand over a lump sum now, but payments start at a future date you choose, often years later. Because the insurer holds and grows the money longer before paying out, deferred income annuities often produce a larger eventual payment for the same deposit.

The real trade-off: liquidity

This is the part that deserves the most attention before you commit. Once you convert a lump sum into an income annuity, that money is generally no longer available to you as a lump sum. You are trading a pool of savings for a predictable paycheck. Some contracts offer limited liquidity features (a cash-refund option, period-certain guarantees, or commutation riders), but these typically reduce the income amount in exchange. The core decision is real: guaranteed income, in exchange for reduced flexibility.

How it works alongside Social Security and a pension

Many retirees use an income annuity to cover a gap between guaranteed income (Social Security, a pension if you have one) and essential monthly expenses, so that the essentials are covered no matter what the market does, while other savings stay invested for growth or stay liquid for flexibility. This "floor plus upside" approach is one of the more common honest use cases for this product.

Who tends to use an income annuity

People who are more worried about running out of money than about maximizing growth, people without a pension who want to recreate pension-like income, and people who specifically want to cover essential expenses with guaranteed income rather than market-dependent withdrawals.

Who it is usually not a fit for

Someone who may need access to that lump sum later for a major expense, someone whose health significantly shortens life expectancy (the payment math works against you if you do not live long enough to collect many payments, though cash-refund options exist for this reason), or someone who already has sufficient guaranteed income covering their essential expenses.

Questions worth asking before you commit

• Is this immediate or deferred, and exactly when do payments start?
• Is this single life or joint life, and how does the payment change if your spouse outlives you, or you outlive them?
• What happens to the remaining balance if you pass away earlier than expected? Is there a cash-refund or period-certain option?
• How much of your total retirement savings is this, and does it leave you enough liquidity for emergencies?
