Fixed vs Variable Annuity: Key Differences

You have decided an annuity belongs in your retirement strategy, but now you face a choice that could shape your financial security for decades: fixed or variable? One promises safety and guarantees. The other offers growth potential but real risk. Choosing the wrong type can mean locking yourself into low returns that lose ground to inflation—or exposing your retirement savings to market losses you cannot afford.

The core difference between a fixed and variable annuity is who bears the investment risk. With a fixed annuity, the insurance company guarantees your rate of return and absorbs all market risk. With a variable annuity, you choose investments and bear the market risk yourself—your account value rises and falls with performance. Everything else—fees, returns, flexibility, and who each product is designed for—flows from that fundamental distinction.

The choice matters enormously. According to LIMRA, fixed annuity sales reached $186 billion in 2023, while variable annuity sales totaled $62 billion—a reflection of how strongly retirees have shifted toward guaranteed products during uncertain markets. But strong sales do not mean fixed annuities are always the better choice. This guide breaks down both options so you can make the right decision for your situation.

How Fixed Annuities Work

A fixed annuity is the simplest annuity product. You give the insurance company a premium (lump sum or series of payments), and they credit your account with a guaranteed interest rate for a set period.

The Guaranteed Rate

When you purchase a fixed annuity, the insurer declares a crediting rate—say 4.5%—that applies for a guaranteed period, typically 3 to 10 years. Some contracts also specify a minimum guaranteed rate (often 1% to 2%) that your crediting rate can never fall below, even after the initial guarantee period expires.

Your principal is fully protected. You cannot lose money due to market performance. The insurance company invests your premium in their general account (primarily bonds and mortgages) and keeps the difference between what they earn and what they credit you.

Fixed Annuity Returns

Fixed annuity rates are influenced by the prevailing interest rate environment. When interest rates are high, fixed annuity rates are more attractive. In recent years, multi-year guaranteed annuity (MYGA) rates have reached 4.5% to 5.5% for 3- to 5-year terms—competitive with CDs and significantly higher than savings accounts.

The trade-off is that your upside is capped. If the stock market returns 25% in a year, your fixed annuity still credits the guaranteed rate. You gain stability but sacrifice growth potential.

Fixed Annuity Fees

One advantage of fixed annuities is their fee simplicity. Most fixed annuities have no explicit annual fees. There are no mortality and expense charges, no administrative fees, and no investment management fees. The insurer profits from the interest rate spread—the difference between what they earn on your premium and what they credit you.

The main cost is the surrender charge, which applies if you withdraw more than the free withdrawal amount (typically 10% per year) during the surrender period. Surrender charges usually start at 7-9% in year one and decline to zero over 5 to 10 years.

How Variable Annuities Work

A variable annuity puts you in the driver's seat. Instead of receiving a guaranteed rate, you allocate your premium among sub-accounts—investment portfolios similar to mutual funds that hold stocks, bonds, international securities, and other assets.

Sub-Accounts and Market Exposure

Variable annuity sub-accounts operate like mutual funds with one major difference: they exist inside an insurance contract, which provides tax deferral and optional guarantees. A typical variable annuity offers 30 to 100+ sub-account options across asset classes.

Your account value fluctuates daily based on sub-account performance. If your stock sub-accounts gain 15%, your annuity value increases. If they lose 20%, your annuity value drops. There is no floor, no protection, and no guaranteed rate on the base contract.

Variable Annuity Returns

The potential returns of a variable annuity are theoretically unlimited—you participate fully in market gains. Over long periods, equity-heavy sub-account allocations have historically produced higher returns than fixed annuity rates.

However, the higher returns come with real volatility. A variable annuity owner who retired in early 2008 and was heavily invested in equity sub-accounts could have seen their balance drop 40-50% before recovering. For someone already drawing income, that kind of loss can permanently damage a retirement plan.

Variable Annuity Fees

This is where variable annuities draw the most criticism. The fee structure is layered and can be substantial:

• Mortality and expense (M&E) charge: 1.0% to 1.5% annually — covers the insurance guarantees and company profit
• Administrative fees: 0.10% to 0.30% annually
• Sub-account management fees: 0.5% to 1.5% annually (similar to mutual fund expense ratios)
• Optional rider fees: 0.5% to 1.5% annually for guaranteed income riders, enhanced death benefits, etc.
• Surrender charges: Similar to fixed annuities, typically 7-8% declining over 6-8 years

Total annual costs can reach 2% to 3.5% when all layers are combined. On a $200,000 contract, that is $4,000 to $7,000 per year in fees. These fees reduce your effective return and are the single biggest argument against variable annuities.

Fixed vs Variable: Side-by-Side Comparison

Risk

Fixed: Zero market risk. Your principal and credited interest are guaranteed by the insurance company's claims-paying ability.

Variable: Full market risk on your sub-account investments. Your balance can decline significantly during downturns.

Return Potential

Fixed: Limited to the declared crediting rate. Typically 3% to 5.5% in current markets. Predictable but modest.

Variable: Unlimited upside tied to market performance. Historical equity returns average 7-10% annually before fees, but actual results vary widely and can be negative.

Fees

Fixed: No explicit annual fees in most contracts. The insurer's profit is embedded in the interest rate spread.

Variable: 2% to 3.5% in annual fees across multiple layers. This is the highest fee structure of any annuity type.

Investment Control

Fixed: None. The insurance company manages the investments and sets your rate.

Variable: Full control over sub-account allocation. You choose your investment mix and can rebalance without triggering taxes (one benefit of tax-deferred status).

Guarantees

Fixed: Guaranteed interest rate, guaranteed principal protection, and guaranteed minimum rate.

Variable: No guarantees on the base contract. However, optional riders can add a guaranteed minimum income benefit (GMIB), guaranteed minimum withdrawal benefit (GMWB), or guaranteed minimum death benefit (GMDB)—for additional fees.

Liquidity

Fixed: Typically 10% penalty-free annual withdrawal. Surrender charges apply to excess withdrawals during the surrender period.

Variable: Similar surrender charge structure. Some contracts offer penalty-free withdrawals of 10% per year or allow access after the surrender period ends.

Regulatory Oversight

Fixed: Regulated by state insurance departments. Not considered securities.

Variable: Regulated by both state insurance departments and the SEC/FINRA, because the sub-accounts are securities. Variable annuities must be sold with a prospectus, and the agent must hold a securities license (Series 6 or 7) in addition to an insurance license.

Riders and Optional Benefits

Both fixed and variable annuities offer optional riders, but they play a more critical role in variable contracts.

Guaranteed Lifetime Withdrawal Benefit (GLWB)

This rider guarantees you can withdraw a set percentage of a "benefit base" (often your highest account anniversary value) for life—regardless of actual account performance. Common withdrawal rates are 4% to 6% depending on your age when payments begin.

For a variable annuity, this rider is transformative: it provides downside protection while allowing you to stay invested in the market. Even if your account drops to zero due to poor market performance and withdrawals, the insurance company continues paying. The cost is typically 0.75% to 1.25% annually.

Fixed annuities can also offer income riders, but since the principal is already guaranteed, the rider's primary function is locking in a higher future income rate.

Enhanced Death Benefit

Standard variable annuity death benefits pay the greater of the account value or total premiums paid. Enhanced riders may offer a "stepped-up" death benefit equal to the highest anniversary value, ensuring your beneficiaries receive at least the peak value of the contract even if the market has declined since.

Nursing Care and Long-Term Care Riders

Some annuities offer riders that increase payments or waive surrender charges if you are confined to a nursing home or need long-term care. These hybrid features can add valuable protection without buying a separate long-term care policy.

Indexed Annuities: The Middle Ground

If the fixed vs variable choice feels too binary, there is a third option: the fixed indexed annuity (FIA).

How Indexed Annuities Work

An indexed annuity guarantees your principal (like a fixed annuity) but credits interest based on the performance of a market index (like a variable annuity). You get some market participation without market risk.

The catch: your upside is limited by caps, participation rates, and spreads.

• Cap: The maximum interest you can earn in a crediting period. If the cap is 10% and the S&P 500 gains 25%, you receive 10%.
• Participation rate: The percentage of the index gain credited to you. A 70% participation rate on a 10% index gain credits you 7%.
• Spread: A percentage subtracted from the index gain. A 2% spread on a 10% gain credits you 8%.

Indexed Annuity Returns

In practice, indexed annuities have historically credited 3% to 7% annually depending on market conditions and contract terms. That falls between the guaranteed rate of a fixed annuity and the uncapped potential of a variable annuity.

The floor is zero—in a bad market year you earn nothing, but you do not lose principal. Over time, the pattern of "some gains, zero losses" can produce competitive returns with far less volatility than direct market exposure.

Who Should Consider an Indexed Annuity?

An indexed annuity fits you if you want more growth potential than a fixed annuity but cannot stomach the market risk of a variable annuity. You are willing to accept capped upside in exchange for guaranteed principal protection. This is especially appealing for people within 5 to 15 years of retirement who want growth but cannot afford a major loss.

Who Should Choose a Fixed Annuity?

A fixed annuity is the right choice if:

• You are risk-averse and prioritize capital preservation above all else
• You are retired or near retirement and cannot afford to lose principal
• You want predictable, guaranteed growth to plan your retirement income with certainty
• You are looking for a CD alternative with higher rates and tax deferral
• You want simplicity — no investment decisions, no sub-account monitoring, no market anxiety

Who Should Choose a Variable Annuity?

A variable annuity makes sense if:

• You have a long time horizon (10+ years) to ride out market fluctuations
• You want market participation with tax-deferred growth
• You value the guaranteed income and death benefit riders that can offset the fees
• You have already maxed out other investment accounts and want an additional tax-deferred vehicle with growth potential
• You are comfortable with investment decisions and actively managing your sub-account allocation

Understanding the Tax Implications

Both fixed and variable annuities enjoy the same favorable tax treatment—tax-deferred growth with no annual capital gains, dividend, or interest taxes. The tax treatment of withdrawals is identical regardless of annuity type: earnings are taxed as ordinary income under LIFO rules for non-qualified contracts, and the entire withdrawal is taxed for qualified contracts.

One advantage of variable annuities is that you can reallocate between sub-accounts without triggering a taxable event. In a taxable brokerage account, selling a fund to buy another would generate capital gains tax. Inside a variable annuity, you rebalance freely.

Making Your Decision

The fixed vs variable decision comes down to three questions:

1. Can you afford to lose money? If a 30% decline in your retirement savings would be catastrophic, choose a fixed annuity or indexed annuity. If you have other assets and time to recover, a variable annuity's growth potential may justify the risk.

2. How long until you need the money? With 15+ years to go, a variable annuity's higher expected returns have time to outpace the fees. With 5 years or less, a fixed annuity's guaranteed rate provides certainty you need.

3. How do you feel about fees? If paying 2-3% annually bothers you, a fixed annuity's no-fee structure may be more appropriate. If you value the riders and guarantees those fees pay for, a variable annuity can still deliver net value.

There is no universally correct answer. Many advisors recommend a blended approach: allocate a portion of your retirement savings to a fixed annuity for baseline security and another portion to a variable or indexed annuity for growth. This gives you guarantees on the money you cannot afford to lose and growth potential on the money you can.
