What is a fixed annuity? A plain-English guide

A fixed annuity is the simplest annuity there is: an insurance contract that pays a guaranteed interest rate for a set number of years, with the tax bill deferred until you take the money out. If that sounds like a bank CD, you're close — the decision between the two comes down to taxes, the guarantee behind the money, and liquidity. This guide covers how fixed annuities work, a worked $100,000 example, how they stack up against CDs, who they fit, who should skip them, and the mistakes that cost people real money.

How a fixed annuity works

You pay the insurer a premium — usually a single lump sum. The insurer credits a guaranteed fixed rate for the contract term. A multi-year guaranteed annuity (MYGA) locks one rate for the entire term and is by far the most popular type. A traditional fixed annuity guarantees its rate for one year, then resets.

Growth is tax-deferred: you owe no tax on the interest until you withdraw it, so your money compounds on the full balance instead of a balance shrunk by yearly tax. When the term ends, you have four choices — cash out, renew at the new rate, annuitize into a guaranteed income stream, or do a tax-free 1035 exchange into a new contract.

A 1035 exchange (named for that section of the tax code) lets you move from one annuity to another without triggering tax on the gains. It restarts the surrender schedule on the new contract, so it only makes sense when the new rate or features clearly justify a fresh lockup.

The real numbers: a worked example

Illustrative, 24% tax bracket, both lines after tax: $6,635 more over 5 years, almost all of it from the rate difference (5.75% vs 4.4%) rather than from deferral. The 4.4% CD leg is an assumed APY, not a quote; the FDIC all-institution average is 1.41%. A MYGA is an insurance contract, not FDIC-insured.

Say you put $100,000 into a 5-year MYGA crediting a guaranteed 5.00%, compounded annually. That's a conservative illustration — among the A- and better carriers we checked on October 13, 2026, 5-year effective yields ran from 3.50% to 6.30%, and the average across all verified carriers was about 5.59%. Because nothing is taxed along the way, the math is clean compounding:

• Year 1: $100,000 × 1.05 = $105,000
• Year 2: $105,000 × 1.05 = $110,250
• Year 3: $115,763
• Year 4: $121,551
• Year 5: $100,000 × 1.05⁵ ≈ $127,628

That's roughly $27,628 of gain, none of it taxed until you touch it. Now compare a 5-year bank CD paying the same 5.00% in a taxable account, where the IRS taxes the interest every year. In a 24% federal bracket, the CD effectively earns 5.00% × (1 − 0.24) = 3.80% after tax, so $100,000 grows to roughly $120,500 over five years. The annuity's $127,628 looks about $7,100 higher, but that is before its deferred tax. Pay 24% on the $27,628 gain when you withdraw and you keep about $121,000 — roughly $500 more than the CD at the same rate and bracket. The edge is bigger if you withdraw in a lower bracket, because you pick the year. Most of any real MYGA-vs-CD gap comes from the rate difference, not the deferral.

One caveat: the tax-deferral edge only exists in a taxable (non-qualified) account, and only matters if your bracket is meaningful. In a 0% or 10% bracket, the gap between a MYGA and a CD shrinks to almost nothing.

Fixed annuity vs. CD

These two get compared constantly because they feel similar — both are safe, both pay a fixed rate, both lock your money for a term. The differences are where the decision lives.

For context on the rate gap (October 2026): 5-year MYGA examples average about 5.59%, while the FDIC national-average 5-year CD pays 1.41% (October 19 release) and the 5-year Treasury yields 5.02% (October 9 close). The FDIC figure is an average across every insured institution — top online banks pay well above it, so compare against a real quote, not the national average.

• Tax: CD interest is taxed yearly; a fixed annuity defers tax — a real edge in a taxable account and a meaningful bracket.
• Guarantee: a CD is FDIC-insured; a fixed annuity is backed by the insurer's claims-paying ability and the state guaranty association (limits vary; see NOLHGA).
• Liquidity: fixed annuities allow about 10% per year penalty-free; early surrender charges can exceed a CD's penalty, and gains taken before 59½ may incur a 10% IRS penalty.

MYGA vs. traditional fixed annuity

"Fixed annuity" is an umbrella term. The two main subtypes are easy to confuse but behave nothing alike — especially around how long the rate is actually guaranteed.

The MYGA term decision: 3, 5, 7, or 10 years

Longer terms have generally paid more, out to about seven years; in this snapshot the 10-year paid slightly less than the 7-year. Here is the picture as of October 13, 2026, read from published product pages — the average effective yield across the carriers we list, and the highest effective yield among A- and better carriers. Carriers re-rate frequently, so check the rate comparison before acting:

• 3-year MYGA: averages about 5.18%; highest effective yield 5.70% (Aspida Synergy Choice, A-)
• 5-year MYGA: averages about 5.59%; highest effective yield 6.30% (Aspida Synergy Choice, A-)
• 7-year MYGA: averages about 5.66%; highest effective yield 6.35% (Aspida Synergy Choice, A-)
• 10-year MYGA: averages about 5.60%; highest effective yield 6.00% (Lincoln Financial MyGuarantee Plus, A)

Some lower-rated carriers advertise higher headline rates: Atlantic Coast Life's Safe Harbor Bonus Guarantee (A.M. Best C+ since September 22, 2026, under review; the carrier also faces regulatory action) posts 7.45% in year one and 6.45% simple interest thereafter on its 5-year term, which works out to about 5.91% effective annual yield. Because simple interest does not compound, never compare a headline rate against a CD's APY — compare effective annual yield to APY.

Two things jump out. The gap between the average and the highest verified effective yield runs from about four-tenths of a point (10-year) to about seven-tenths (5- and 7-year) depending on term — so shopping carriers matters at least as much as picking the perfect term. And the top of the rate board may belong to a carrier with a lower financial-strength rating, so check the A.M. Best rating before you chase yield.

The term trade-off itself is reinvestment risk versus flexibility. A longer lock protects you if rates fall but shuts you out of higher rates if they rise. That tension is exactly why laddering — covered below — is the standard answer for larger balances.

Who a fixed annuity fits — and who should skip it

This is a decision, not a default, so frame it around fit.

Good fit

• Conservative savers who want a guaranteed rate that usually beats a comparable CD after tax.
• People in a meaningful tax bracket holding cash in a taxable account who value deferral.
• Pre-retirees and retirees who can leave the money alone for the full surrender term.
• Anyone wanting principal protection with zero market exposure.

Poor fit

• Money you might need before the surrender period ends — a CD or high-yield savings is more liquid.
• Savers under 59½ who'd face the 10% IRS early-withdrawal penalty on gains.
• People who already have tax deferral inside an IRA, where the annuity's main edge vanishes.
• Investors who need growth to outpace inflation over decades — a fixed rate may not.

How to use MYGAs in a portfolio

Build a ladder. Instead of putting everything into one term and betting on rates, you stagger maturities so a rung comes due every few years. A typical retiree ladder might look like this:

Spreading the rungs across more than one carrier also reduces single-insurer risk. Every two to three years a rung matures and gets re-laddered at then-current rates. That smooths interest-rate timing risk and produces a predictable, blended yield that — for taxable investors — typically lands above bank CDs after tax and can edge out Treasuries. Compare it against a same-maturity Treasury ladder, whose interest is free of state income tax.

Common mistakes to avoid

• Treating the guaranty association as your protection. Coverage is a capped, last-resort backstop whose limits vary by state, not a reason to buy. Choose the carrier on its own financial strength.
• Ignoring the surrender schedule. Touching more than the free-withdrawal amount can wipe out a year or more of interest.
• Letting it auto-renew. Many contracts roll into a new term — and a new surrender period — at a lower rate if you miss the maturity window.
• Chasing the top rate without checking the carrier. The highest rate on the board may belong to a carrier with a lower financial-strength rating. Check the A.M. Best rating first, then compare effective yields. Our top-rate examples use A- or better as a floor; a higher headline rate does not make up for a carrier facing regulatory action.
• Buying inside an IRA for the tax break. There isn't one — the IRA already defers tax.

Annuities are regulated as insurance products at the state level, and salespeople earn commissions, so confirm any pitch against a primary source. The FINRA investor education library and the SEC's annuity basics are good neutral starting points before you sign.

How to buy one: next steps

1. Set the goal. Decide how much you can lock up and for how long without needing it.
2. Check the account type. A taxable account with a meaningful bracket favors a MYGA; an IRA tilts the math toward CDs or Treasuries.
3. Compare rates and terms across multiple A.M. Best-rated carriers for the term you want.
4. Verify carrier strength — A.M. Best rating, licensing and complaint history — before committing; for a large balance, spreading it across more than one strong insurer reduces single-carrier risk.
5. Read the surrender schedule and free-withdrawal terms line by line, then calendar the maturity date so you control what happens at the end.

Run your own numbers — premium, term, and bracket — through the calculator above before you decide, and don't let a quoted rate alone make the call.
