This guide explains the categories so the word "annuity" stops being confusing. It will not tell you what to buy, that depends on your situation. When you are ready to apply it to your own numbers, you can book a free review.

Start Here: The One-Sentence Definition

Strip away the jargon and an annuity is simple: a contract with an insurance company where you hand over money, and in return the company promises something back, either a guaranteed growth rate, protection of your principal, or a stream of income you cannot outlive.

That is it. The confusion starts because the word covers at least six very different products that make very different promises. Saying "I am thinking about an annuity" is a little like saying "I am thinking about a vehicle." The next question is always which kind, and for what job?

This guide answers exactly that. By the end you will be able to tell the families apart and know which tends to fit which goal, which is most of what it takes to read any annuity conversation clearly.

The Two Questions That Define Every Annuity

You can place almost any annuity by answering just two questions. Get these, and the six types below stop feeling like alphabet soup.

Question 1: When Does Income Start?

Immediate annuities begin paying you right away (within about a year). Deferred annuities grow now and pay later, sometimes years later. Many people never turn on income at all and use the deferred version purely for protected growth.

Question 2: How Does the Money Grow?

  • Fixed: a set interest rate, like a CD from an insurer. Fully predictable.
  • Indexed: growth is linked to a market index but with a 0% floor. You do not lose principal in a down year, in exchange for a cap on the upside.
  • Variable: your money is invested in market subaccounts. The most upside, but also full market risk and the highest fees.
The whole map in one line: pick when (now or later) and how it grows (fixed, indexed, or variable), and you have essentially named the product. Everything else is features and fine print.

The Six Types, One by One

Here is each family stated plainly: what it does, who it tends to fit, and what to watch for.

1

Single-Premium Immediate Annuity (SPIA)

Income Now · The "Private Pension"
What It Does
You give a lump sum; the insurer sends a guaranteed paycheck starting almost immediately, for life or a set period.
Tends to Fit
Someone retiring now who wants essential expenses covered by income they cannot outlive.
Watch For
It is usually irrevocable. You trade access to the lump sum for the income.
Growth Style
Based on rates and life expectancy, not markets.
2

Deferred Income Annuity (DIA)

Income Later · Lock In a Future Paycheck
What It Does
Same as a SPIA, but income starts on a future date you choose; the wait raises the eventual payout.
Tends to Fit
Someone 5 to 10 years from retirement who wants to lock in future income now.
Watch For
Money is committed during the waiting years.
Growth Style
Fixed schedule set at purchase.
3

Multi-Year Guaranteed Annuity (MYGA)

Fixed Growth · The Insurer's "CD"
What It Does
Pays a fixed, guaranteed rate for a set term (commonly 3 to 7 years), tax-deferred.
Tends to Fit
Savers who want a known, safe return better than a bank CD, with no market risk.
Watch For
Surrender charges if you exit early; rate resets at the end of the term.
Growth Style
Fixed. Essentially no annual fee; the rate is the return.
4

Fixed Annuity

Fixed Growth · Simple and Predictable
What It Does
A guaranteed interest rate with principal protection; the broad family MYGAs belong to.
Tends to Fit
Conservative savers prioritizing certainty over upside.
Watch For
Lower long-run growth than markets; inflation can erode fixed payments.
Growth Style
Fixed and predictable.
5

Fixed Indexed Annuity (FIA)

Protected Growth · 0% Floor, Capped Upside
What It Does
Credits interest linked to an index (like the S&P 500) with a 0% floor, no negative years, in exchange for a cap on gains.
Tends to Fit
Savers who want some market-linked growth on money they cannot afford to lose.
Watch For
Caps and crediting formulas can be complex; optional riders add cost.
Growth Style
Indexed, principal-protected; no explicit annual fee unless you add a rider.
6

Variable Annuity (VA)

Market Growth · Most Upside, Most Cost
What It Does
Invests your money in market subaccounts; value rises and falls with the market.
Tends to Fit
A narrower set of cases; this is the product most critics are warning about.
Watch For
Total fees often run 2.5% to 4% a year, and you can lose principal.
Growth Style
Variable. Full market exposure.

A Note on the Seventh

The buffered, or registered index-linked, annuity (RILA) sits between indexed and variable: partial protection, partial market exposure.

Which Type Tends to Fit Which Goal

Match the job to the tool. The honest version of this table includes its last row: for pure long-term growth, a low-cost investment portfolio is often the better choice, and an annuity is not needed at all.

If Your Goal IsThe Type That Tends to FitWhy
A paycheck for life, starting nowSPIA (immediate income)Guaranteed income you cannot outlive.
A future paycheck, locked in todayDIA (deferred income)The wait increases the guaranteed payout.
A safe, known return better than a CDMYGA / FixedFixed rate, tax-deferred, no market risk.
Market-linked growth with no down yearsFixed Indexed (FIA)0% floor protects principal; upside is capped.
Maximum growth, willing to take risk and costVariable, or just stay investedFull market exposure with the highest fees.

The balanced truth. Annuities are specialists, not all-purpose accounts. Each type does one job well and gives something up to do it. The skill is matching the product to the part of your plan that needs that specific job done.

The Trade-Offs Every Annuity Shares

However different the six types are, they share a family resemblance: the same trade-offs show up in every contract. Know these and you will never be surprised by the fine print.

Liquidity Is Limited

Most annuities let you withdraw a set amount each year penalty-free (commonly 10%), but taking more during the surrender period (often 5 to 10 years) triggers a charge that typically starts high and steps down each year. Annuities are long-term tools by design.

Taxes Are Deferred, Then Ordinary

Money grows tax-deferred, but withdrawals of earnings are taxed as ordinary income, not at lower capital-gains rates, and before age 59½ a 10% IRS penalty can apply on the taxable portion. Inside an IRA, the tax deferral is redundant, which is why that pairing draws criticism.

The Guarantee Is Only as Strong as the Carrier

An annuity's promises rest on the insurer's claims-paying ability, so the company's financial-strength rating (AM Best, S&P, Moody's, Fitch) matters. A state guaranty association provides a backstop up to limits if a carrier fails, but the first line of safety is choosing a strong, highly rated company.

If anyone tells you to put everything in one annuity, that is your signal to get a second opinion. Most people are best served by a protected or income layer for what must be certain, and a growth portfolio for everything else.
