How Do Annuities Work?

An annuity works in two phases. During the accumulation phase, your money grows, either at a fixed rate or linked to a market index, protected from the losses a market downturn could otherwise cause. During the payout phase, you convert that value into income: a lump sum, payments for a set number of years, or payments guaranteed for as long as you live. That structure exists to solve one specific problem, outliving your own savings. Every other feature, from payout options to death benefit rules, exists to fine-tune how and when that protection actually reaches you.

Key Takeaways

  • Every annuity moves through two phases: accumulation (your money grows) and payout (you receive income)

  • Immediate annuities skip the accumulation phase and start paying out within about a year. Deferred annuities grow for years before payout begins

  • You choose how payments are structured: for a set period, for your lifetime, or for two lives (you and a spouse)

  • Most annuities don't include a death benefit by default. If dying before payout matters to you, it has to be built in on purpose

  • Withdrawing money early, before the surrender period ends, generally comes with a penalty

The Two Phases of Every Annuity

How does an annuity work once you strip away the product names and riders? Every annuity is really just two phases stitched together.

Phase 1:

Accumulation

This is the growth period. You fund the annuity, either with a single lump sum or a series of payments, and your money grows on a tax-deferred basis. Depending on the type of annuity, that growth might be a fixed interest rate, index-linked crediting with a floor and a cap, or returns tied to underlying investments. This phase can last anywhere from about a year to several decades.

Phase 2:

Payout (Annuitization)

If you're asking what is annuitization in practice, this is it: the point when the annuity does the job it was actually built for, converting your accumulated value into income. You choose how that income is structured, and once annuitized, that choice is generally locked in. This is also the phase where "guaranteed income" becomes real, backed by the issuing insurer's claims-paying ability, not the stock market's performance that day.

Not every annuity holder annuitizes. Some withdraw funds as needed instead, or pass the account value on to heirs. Annuitizing is a choice, not an automatic requirement, and it's one of the more important decisions in how an annuity actually plays out for you.

Immediate vs. Deferred: When Does the Income Start?

Immediate annuities skip most or all of the accumulation phase. You fund it with a lump sum, and payments typically begin within a year, sometimes within a month. These fit people who are already at or near retirement and want income now, converting savings into a paycheck-like stream immediately.

Deferred annuities grow for a period, often years or decades, before payout begins. You choose when to start receiving income, which gives you flexibility to time it around retirement, other income sources, or tax planning. Most of the annuities Team Thrive works with are deferred, funded during working years and converted to income later.

The immediate vs deferred annuity choice usually comes down to one question: do you need income now, or are you still building toward retirement?

Payout Options: How Your Income Actually Gets Structured

Once you annuitize, you choose a payout structure. Understanding the different annuity payout options matters more than most people expect, because this decision shapes how much you receive and for how long, and it's typically locked in once made.

Payout Option How It Works Best For
Life Only Payments continue for as long as you live, then stop. Generally the highest payment amount. Maximizing monthly income, no dependents relying on continued payments
Life with Period Certain Payments continue for life, but guaranteed for a minimum number of years even if you pass away early. Wanting lifetime income with some protection for heirs
Joint and Survivor Payments continue as long as either you or a named survivor (often a spouse) is living. Married couples wanting income protection for both lives
Period Certain (Fixed Period) Payments continue for a set number of years, regardless of whether you're still living. A specific income gap, like bridging to Social Security or a pension

Does an Annuity Have a Death Benefit?

An annuity death benefit isn't automatic. Generally, no, not by default. This is one of the most common points of confusion, especially for people comparing an annuity to life insurance. If you pass away during the accumulation phase, many annuities pay your beneficiary the account's value, but that's a return of what's there, not a life-insurance-style payout. What happens to annuity when you die? It depends entirely on timing. If you've already annuitized under a Life Only option and pass away shortly after, payments can simply stop, with nothing further paid to heirs. Riders exist that add death benefit features, but they typically come at an additional cost and have to be selected on purpose. If a death benefit matters to you, don't assume it's automatically included. Ask specifically.

How Are Annuities Taxed?

Growth inside an annuity is tax-deferred, meaning you don't pay taxes on gains each year the way you might with a taxable brokerage account. Taxes come due when you withdraw or begin receiving payments. How much of each payment is taxable depends on whether the annuity was funded with pre-tax money (like a rollover from a 401(k), where the full payment is generally taxable) or after-tax money (where only the growth portion is generally taxable, and the return of your original contribution isn't). Withdrawals before age 59½ can also trigger a 10% IRS early withdrawal penalty, in addition to ordinary income tax on the taxable portion. Tax treatment depends on your specific situation, and this isn't tax advice, your advisor and a tax professional can walk through the specifics for your annuity.

What Is a Surrender Period?

An annuity surrender period is a set number of years, typically several, during which withdrawing more than a set amount (often 10% annually) triggers a surrender charge. This charge usually starts higher in the early years and declines over time until it reaches zero. It exists because the insurer is making long-term guarantees and pricing the product around you keeping funds in place. It's one of the most important things to understand before funding an annuity: this generally isn't money you want to plan on accessing freely in the short term.

Who Tends to Benefit Most From an Annuity?

A lifetime income annuity, specifically, tends to fit you if:

  • You want income you structurally cannot outlive, regardless of how long retirement lasts

  • You're uneasy about managing withdrawals from a portfolio yourself, especially during market downturns

  • You don't need the funds to be liquid or accessible in the near term

  • You've already built emergency savings elsewhere, this isn't meant to be that

It may not fit you if:

  • You need full, penalty-free access to these funds in the next several years

  • Leaving a specific inheritance amount to heirs is a top priority, and you haven't added a death benefit rider

  • You're comparing it purely as a growth investment rather than an income tool

Common Mistakes to Avoid

Funding an annuity with money you might need soon

The surrender period exists specifically to discourage early withdrawals, and the penalty is real

Assuming a death benefit is automatically included

For most annuities, it isn't, unless you specifically add it

Annuitizing under Life Only without considering a spouse or dependent

Once payments start, that choice is typically permanent

Treating an annuity like a savings account

It's built for guaranteed income, not day-to-day liquidity

Frequently Asked Questions

How long does the accumulation phase last?

It varies by product and by your choice. It can be as short as about a year for an immediate annuity, or span decades for a deferred annuity funded well before retirement.

Can I withdraw money from an annuity before the payout phase?

Generally yes, up to a certain amount, often 10% annually, without a surrender charge. Withdrawing more than that during the surrender period typically triggers a penalty, on top of possible income tax and an early withdrawal penalty if you're under 59½.

What happens to my annuity if I die before annuitizing?

In most cases, your named beneficiary receives the account's value. This is different from annuitizing, since the account hasn't yet been converted into an income stream.

What happens to my annuity payments if I die after annuitizing?

It depends entirely on the payout option you chose. Life Only payments generally stop. Life with Period Certain or Joint and Survivor options continue paying out under specific conditions. This is exactly why the payout choice matters so much.

Is annuity income guaranteed no matter what?

Guaranteed payments are backed by the claims-paying ability of the issuing insurance company, not by a government program the way FDIC insurance backs a bank account. The strength of that guarantee is tied to the insurer's financial strength.

Can I lose money in an annuity?

It depends on the type. Fixed and fixed indexed annuities generally protect your principal from market losses through a floor. Variable annuities, which invest in underlying subaccounts, can lose value. Ask specifically which category a product falls into before assuming principal protection applies.

Is an annuity the same thing as an IUL?

No, though the two get compared often. An annuity's core purpose is converting savings into guaranteed income. An IUL is life insurance that includes a death benefit, with cash value growth as an additional feature. See our full comparison for the details.
