Fixed Annuities Explained: Guaranteed Rates, Predictable Growth

What Exactly Is a Fixed Annuity?

A fixed annuity is a close cousin to a CD, with a few more features. You hand a lump sum (or a series of payments) to an insurance company, and in return they guarantee a specific interest rate for a specific period of time. The money grows. Taxes wait until withdrawal. And when retirement income becomes the goal, you'll find several options on the table.

That's the short version. There's more under the hood, and it's worth understanding before any contract gets signed.

A fixed annuity is an insurance contract — not a bank product, and not a security. That distinction matters because it shapes who regulates it, how it's protected, and how it's taxed. Insurance companies issue these contracts, state insurance departments regulate them, and state guaranty associations back them up if a carrier runs into trouble.

The "fixed" part is the key word. Unlike variable annuities where returns ride the market, a fixed annuity locks in a rate. You know what you're getting. No surprises, no market risk, no checking a portfolio at 6 a.m. wondering whether to panic.

How Fixed Annuities Actually Work

The lifecycle of a typical fixed annuity has four phases.

1. The contract is funded. A single lump-sum deposit (a single premium) is most common, though some contracts accept multiple deposits over time (flexible premium). Minimums vary — some carriers start as low as $5,000, while others require $25,000 or more.

2. The accumulation phase begins. The insurance company credits the account with interest at the guaranteed rate. That rate might be locked for the entire contract (common with MYGAs) or guaranteed only for the first year with renewal rates set annually afterward (common with traditional fixed annuities).

3. Money grows tax-deferred. Unlike a savings account or CD that triggers a 1099 every year, the IRS doesn't touch fixed annuity gains until withdrawal. Over long time horizons, this matters — interest earns interest without the annual tax drag.

4. Access begins. When the time comes, withdrawals can be taken, the contract can be annuitized for guaranteed income, or the balance can be rolled into another annuity (a 1035 exchange) without triggering taxes.

The Guaranteed Rate vs. the Current Rate

This trips people up, so it's worth being precise. Many fixed annuities feature two rates:

• The current rate — what the company is actually crediting right now. This is the headline number in marketing material.
• The minimum guaranteed rate — the contractual floor below which the rate can never drop, typically 1–3%.

With a multi-year guaranteed annuity (MYGA), the current rate is the guaranteed rate for the full term — say 5 years at 5.25%. Clean and predictable. With a traditional fixed annuity, the company can adjust the current rate annually after the initial guarantee period, but it can never fall below the contractual minimum.

Fixed Annuities vs. CDs: The Real Comparison

The most common question about fixed annuities is "why not just buy a CD?" It's a fair one. Here's the honest breakdown.

Where fixed annuities win:

• Tax deferral. CD interest is taxed annually as ordinary income. Fixed annuity interest is not taxed until withdrawal. Over 5–10 years, that compounding advantage adds up — especially in a high tax bracket now with a lower one expected in retirement.
• Higher rates. Fixed annuities, particularly MYGAs, frequently offer rates 0.25–0.75% above comparable-term CDs.
• Income conversion. A fixed annuity can be annuitized into guaranteed lifetime income. A CD can't.
• Probate avoidance. Annuities pass to named beneficiaries outside of probate.

Where CDs win:

• FDIC insurance. CDs are backed by the full faith and credit of the U.S. government (up to $250,000). Annuities are backed by the insurance company and state guaranty associations — strong, but not the same thing.
• Liquidity. Early withdrawal penalties on CDs are typically much smaller than annuity surrender charges.
• Simplicity. No riders, no surrender schedules, no insurance company to evaluate.

Neither product is objectively "better." They simply serve different roles.

Deferred vs. Immediate: Two Flavors of Fixed

Fixed annuities come in two broad categories.

Deferred Fixed Annuities

Money goes in now, grows at a guaranteed rate, and is accessed later. This is the accumulation vehicle — the savings tool. Most of this article applies to deferred fixed annuities. MYGAs fall into this group.

Immediate Fixed Annuities (SPIAs)

A lump sum goes in, and income payments start right away — usually within 30 days. There is no accumulation phase; you're converting a pile of money into a guaranteed paycheck. See the immediate annuities guide for details.

The right choice hinges entirely on timeline. Growth needed for 5–10 years before retirement? Deferred. Income needed next month? Immediate.

Surrender Periods: The Trade-Off for Higher Rates

This is the part nobody loves but everyone needs to understand. When an insurance company guarantees a competitive rate, they need to invest the money for a similar duration to make good on the promise. The surrender period is how they protect themselves — and, indirectly, you — from a run on withdrawals.

How surrender charges work:

• Typical surrender periods run 3–10 years.
• Charges usually start at 5–10% of the withdrawal amount in year one and decline by about 1% per year.
• Most contracts include a free withdrawal provision — typically 10% of the account value per year — with no surrender charge.
• After the surrender period ends, the entire balance becomes fully liquid.

A typical 7-year surrender schedule looks like:

Tax Treatment: The Details That Matter

Fixed annuities get favorable tax treatment, though the rules have some nuance.

During accumulation:

• Interest grows tax-deferred. No annual 1099. No current tax liability.

When you withdraw:

• Earnings come out first (this is called LIFO — last in, first out). Those earnings are taxed as ordinary income, not capital gains.
• Once all the earnings have been withdrawn, the remaining withdrawals are a return of original premium and are tax-free.

The 10% early withdrawal penalty:

• Withdrawals before age 59½ trigger a 10% IRS penalty on the earnings portion — on top of ordinary income tax.
• Exceptions exist: disability, death, and certain annuitized payment schedules (72(t) distributions).

Qualified vs. non-qualified:

• If a fixed annuity is funded with IRA or 401(k) money (qualified funds), the entire withdrawal is taxable because a tax deduction was already taken going in.
• If funded with after-tax money (non-qualified), only the earnings portion is taxable.

1035 exchanges:

• One annuity can be transferred to another without triggering taxes. This is how people "upgrade" to a better rate or product when a surrender period ends.

Who Fixed Annuities Are Best For

Fixed annuities aren't for everyone. They're a specific tool for specific situations. They shine for:

• Conservative pre-retirees (ages 55–70) who want guaranteed growth without market risk on money needed in 5–10 years.
• People who've maxed out other tax-deferred accounts (401k, IRA) and want additional tax-deferred savings — there are no IRS contribution limits on non-qualified annuities.
• CD holders tired of paying annual taxes on interest they're not spending.
• Anyone building a "safe money" bucket in a retirement income strategy — the portion of a portfolio that needs to be predictable.

They're probably not the right fit if:

• You're young with a long time horizon (more market exposure likely makes sense).
• You might need the money within the surrender period.
• You're already in a very low tax bracket (the tax deferral benefit is minimal).

Things to Watch Out For

The pitfalls that come up most often:

Chasing the highest rate without checking the carrier. A 6% rate from a poorly rated insurance company isn't a bargain — it's a risk. Always check the carrier's AM Best, S&P, or Moody's ratings. A-rated or better is the reasonable baseline.

Ignoring the renewal rate history. With traditional fixed annuities, the first-year teaser rate might be great, but what does the company typically renew at? Ask for the carrier's renewal rate history. Some companies are known for steep drop-offs.

Buying a longer surrender period than you need. Yes, longer surrender periods usually mean higher rates. But if the money is needed in year four of a 10-year contract, that extra 0.3% rate advantage won't offset the surrender charge.

Forgetting about inflation. A 5% fixed rate feels great today. Over 10 years, inflation can erode purchasing power. Fixed annuities are a piece of the puzzle — not the entire puzzle.

Misreading the free withdrawal provision. Some contracts calculate the 10% free withdrawal based on premium, others on the accumulated value. It matters. Read the contract carefully.

The Bottom Line

Fixed annuities are one of the simplest, most predictable tools in the retirement planning toolbox. They won't make you rich. They won't beat the stock market over 20 years. That isn't what they're for.

They're for the portion of money that absolutely, positively needs to be there at retirement. The money that can't afford to be lost. The money that needs to grow steadily, tax-efficiently, and without drama.

If that fits what's needed, an independent comparison of rates, surrender periods, and carrier strength is the next step — those details make a real difference in the outcome.
