Annuity Glossary: Plain-English Definitions of Every Key Term

Annuity contracts are written in a vocabulary nobody uses anywhere else. This glossary defines every term you'll actually meet — in a quote, an illustration, or the contract itself — with links to our deeper guides where a definition deserves a full article.

If you're brand new, start with what an annuity is and the types of annuities, then keep this page as your reference. The category sections of this glossary — product types, people and paperwork, rates and crediting, fees, income, tax, and safety — live in the filter chips below.

Frequently Asked Questions

What is the difference between the owner and the annuitant?

The owner is the person who buys the contract, controls it, and pays taxes on withdrawals. The annuitant is the person whose life expectancy the insurer uses to calculate payments. They're usually the same person, but they don't have to be — and when they differ, the contract's death-benefit and tax consequences can change, so the roles are worth setting deliberately.

What does it mean to annuitize an annuity?

Annuitizing converts a contract's accumulated value into a stream of guaranteed payments — for life, for a set period, or a combination. The conversion is generally irreversible: you trade access to the lump sum for the income guarantee. Which structure you pick (life-only, period certain, joint and survivor, or refund) determines the size of each payment and what happens when you die.

What is a surrender charge on an annuity?

A surrender charge is the fee an insurer deducts when you withdraw more than the contract allows during the surrender period — the first several years of the contract. The charge typically starts as a percentage of the amount withdrawn and declines each year until it reaches zero. Most contracts soften it with a penalty-free withdrawal allowance each year, commonly the interest earned or a set percentage of the value.

What do cap rate and participation rate mean on an indexed annuity?

Both limit how much of an index's gain your contract is credited. A cap is a ceiling: if the cap is, say, 8% and the index rises more, you get the 8%. A participation rate is a fraction: at a 50% participation rate you're credited half of the index gain. Both figures are hypothetical - actual caps and participation rates vary by product and change over time. Some products use one, some use both, and some use a spread instead — a fixed amount subtracted from the gain before crediting.

What is the difference between a qualified and non-qualified annuity?

A qualified annuity is held inside a retirement account like an IRA or 401(k), funded with pre-tax dollars, and fully taxable on withdrawal. A non-qualified annuity is bought with after-tax money outside any retirement account, so only its earnings are taxed when withdrawn. The qualified version follows retirement-account rules — contribution limits and required minimum distributions — while the non-qualified version has neither.
