Annuity vs. Mutual Funds: Which Belongs in Your Retirement Plan?

If you are within ten years of retirement and sitting on $200,000 or more in savings, you have probably asked yourself the same question: Should I put my money into annuities, mutual funds, or some combination of the two?

The short answer is that each product solves a different problem. Mutual funds are built for growth. Annuities are built for guaranteed income and principal protection. The right choice depends on how much risk you can stomach, when you need the money, and whether running out of income in your 80s keeps you up at night.

This guide breaks down the real differences, with current rate data, actual fee numbers, and tax rules so you can make a confident decision.

Quick Comparison: Annuities vs. Mutual Funds at a Glance

How Do Annuities and Mutual Funds Actually Work?

An annuity is a contract between you and an insurance company. You hand over a lump sum (or make periodic payments), and the insurer guarantees you a rate of return, a stream of income, or both, depending on the type of annuity you choose.

A mutual fund pools money from thousands of investors and buys a basket of stocks, bonds, or other securities. Your returns depend entirely on how those underlying investments perform. There is no insurance company backing your balance.

The core tradeoff is straightforward: annuities trade upside potential for certainty, while mutual funds trade certainty for upside potential. Understanding that single distinction will frame every other comparison in this article.

What Returns Can You Expect from Each?

Mutual funds tied to the S&P 500 have delivered an average annual return of approximately 10.26% from 1957 through 2024. That is a strong long-term number, but it masks brutal short-term swings. In 2008, the S&P 500 dropped 38.49%. An investor with $300,000 in an S&P 500 index fund on January 1, 2008 saw their balance fall below $185,000 by year-end.

Fixed annuities and MYGAs, by contrast, deliver predictable returns. As of April 2026, top-rated A-rated carriers are offering 5.65% on 5-year MYGAs and 5.60% on 7-year terms (source: AnnuityRateWatch). Your principal never drops, regardless of what happens in the stock market.

Consider David, age 64, with $350,000 to invest. If he puts that entire amount into a 5-year MYGA at 5.65%, he will have approximately $460,400 at maturity, guaranteed. If he invests the same amount in an S&P 500 index fund, he could end up with more, but he could also end up with less. At 64, David has to decide how much uncertainty he can afford.

Are Annuity Fees Really Higher Than Mutual Fund Fees?

It depends entirely on the type of annuity. This is one of the most misunderstood topics in retirement planning, because people lump all annuities together.

Fixed annuities and MYGAs charge no explicit fees. There is no annual expense ratio, no management fee, and no administrative charge deducted from your account. The insurance company makes money on the spread between what they earn investing your premium and the rate they guarantee you. You see exactly what you earn.

Variable annuities are a different story. Total annual costs typically range from 2.0% to 3.5%, stacked across mortality and expense charges (1.0%-1.5%), underlying fund expenses (0.5%-1.0%), and optional rider fees for income or death benefit guarantees (0.5%-1.0%). The SEC’s guide to variable annuities breaks down these layers in detail.

Meanwhile, a low-cost index fund like Vanguard’s Total Stock Market Index Fund (VTSAX) charges just 0.04% per year. On a $200,000 investment, that is $80 annually versus $4,000 to $7,000 per year inside a variable annuity.

If you are comparing a MYGA to a mutual fund, fees are a non-issue. If you are comparing a variable annuity to a mutual fund, fees matter enormously. For a deeper breakdown, see our guide to annuity fees explained.

How Are Annuities and Mutual Funds Taxed Differently?

Both annuities and mutual funds held inside qualified accounts like 401(k)s and IRAs grow tax-deferred. The differences show up when you hold mutual funds in a taxable brokerage account or when you start taking withdrawals.

Mutual funds in a taxable account benefit from favorable capital gains tax rates. If you hold shares for longer than one year, your profits are taxed at the long-term capital gains rate of 0%, 15%, or 20%, depending on your income. Most retirees fall into the 15% bracket. You also get a step-up in cost basis at death, which can erase capital gains taxes for your heirs entirely.

Annuity withdrawals are taxed as ordinary income on the gain portion, which means federal rates of 10% to 37%. There is no capital gains treatment. Annuities also follow a “last in, first out” (LIFO) rule for non-qualified contracts, meaning gains come out first and are fully taxable. At death, heirs do not receive a step-up in basis.

For someone in the 22% or 24% federal tax bracket, this difference can add up. Patricia, age 67, withdraws $30,000 in gains from her annuity and pays $7,200 in federal tax at 24%. If she had taken that same $30,000 as long-term capital gains from a mutual fund, she would owe $4,500 at the 15% rate, saving $2,700.

That said, if you are already maxing out your 401(k) and IRA, an annuity can still provide additional tax-deferred growth that a taxable brokerage account cannot.

Can Mutual Funds Guarantee Retirement Income?

No. Mutual funds do not offer any form of guaranteed income. You can set up systematic withdrawals from a mutual fund account, but the amount you can safely take depends on market performance, and there is always a risk of running out of money.

The traditional “4% rule” suggests withdrawing 4% of your portfolio in year one and adjusting for inflation each year after. But a bad sequence of returns early in retirement can deplete a mutual fund portfolio faster than expected. A retiree who retired in January 2008 with $500,000 in stocks and a $20,000 annual withdrawal would have seen their portfolio drop to roughly $290,000 within a year, before a single dollar of income was taken.

Annuities solve this problem by shifting the longevity risk to the insurance company. A single-premium immediate annuity (SPIA) or a deferred annuity with an income rider can guarantee a monthly check for life, no matter how long you live or what the stock market does.

For retirees whose primary concern is “Will I outlive my money?”, annuities answer that question definitively in a way that mutual funds simply cannot.

Which Is More Liquid: Annuities or Mutual Funds?

Mutual funds win on liquidity by a wide margin. You can sell shares of most mutual funds on any business day and have cash in your account within one to two days. There are no penalties, no surrender charges, and no waiting periods (assuming you are past any short-term redemption fees, which are rare on most funds today).

Annuities come with surrender charge periods, typically ranging from 3 to 10 years depending on the product. If you withdraw more than the penalty-free amount (usually 10% of your account value per year) during the surrender period, you will pay a charge that can range from 1% to 8% or more in the early years.

This is why financial planners recommend that you never put money into an annuity that you might need for emergencies. The money you commit to an annuity should be money you are confident you will not need to access for the duration of the surrender period.

When Should You Choose an Annuity Over Mutual Funds?

An annuity makes the most sense when you need predictable outcomes. Here are the situations where an annuity is typically the better choice:

• You are within 5-10 years of retirement and cannot afford a major market loss. A 5-year MYGA at 5.65% protects your principal while still earning competitive returns.
• You want guaranteed lifetime income. If Social Security and any pension do not cover your essential expenses, an annuity can fill the gap permanently.
• You have already maxed out your 401(k) and IRA and want additional tax-deferred growth. Non-qualified annuities offer unlimited contributions with no annual cap.
• You are a conservative investor who cannot sleep at night during market downturns. A fixed annuity eliminates market anxiety entirely.
• You want a bond alternative. With MYGAs paying 5.60%-5.65%, many advisors now recommend them as a replacement for the bond portion of a portfolio. See our comparison of annuities vs. bonds for more detail.

When Should You Choose Mutual Funds Over an Annuity?

Mutual funds make more sense when you have time on your side and can tolerate volatility. Here is when they are typically the better choice:

• You are more than 10 years from retirement and can ride out market downturns. The longer your time horizon, the more likely stocks are to outperform fixed-rate products.
• You want full liquidity. If you might need access to your money at any time, mutual funds provide daily liquidity with no surrender penalties.
• You want the lowest possible fees. A total market index fund at 0.04% per year is hard to beat on cost. You can research fund options and performance data at Morningstar.
• You want tax-efficient growth in a taxable account. Long-term capital gains rates of 0%-20% beat ordinary income rates on annuity withdrawals, and the step-up in basis at death is a significant estate planning advantage.
• Your essential expenses are already covered by Social Security, pensions, or other guaranteed income. If your baseline needs are met, you can afford to take more risk with the rest.

Can You Use Both Annuities and Mutual Funds Together?

Yes, and many financial planners recommend exactly this approach. It is called the “floor and upside” strategy, and it is one of the most practical frameworks for retirement income planning.

The concept is simple. First, calculate your essential monthly expenses: housing, food, insurance, utilities, healthcare. Then use guaranteed income sources (Social Security, pensions, and annuities) to cover that floor. Whatever is left over goes into mutual funds for growth, discretionary spending, and legacy goals.

Here is how this might look in practice. Linda, age 63, has $400,000 in savings and expects $2,200 per month from Social Security starting at 67. Her essential expenses are $4,000 per month. She puts $150,000 into a SPIA that will pay roughly $900 per month starting at 67, bringing her guaranteed floor to $3,100. She puts another $100,000 into a 5-year MYGA at 5.65% to grow safely until she needs it. The remaining $150,000 stays in a diversified mutual fund portfolio for growth and flexibility.

This approach gives Linda guaranteed income to cover most of her essentials, a safe bucket earning competitive rates, and a growth bucket for travel, gifts, and inflation protection. She sleeps well at night knowing her bills are covered, even if the stock market drops 30%.

The floor-and-upside strategy is also closely related to the question of annuity vs. 401(k), since many retirees are deciding how to allocate their 401(k) rollover between guaranteed and growth-oriented options.

What About Variable Annuities vs. Mutual Funds?

Variable annuities invest in mutual fund-like “sub-accounts” and layer insurance guarantees on top. In theory, you get market participation plus downside protection. In practice, the high fees often erode returns to the point where you would have been better off with a plain mutual fund.

A variable annuity charging 3.0% per year needs to earn 3.0% just to break even. Meanwhile, an investor in VTSAX at 0.04% keeps almost every dollar of return. Over 20 years, that fee drag can cost tens of thousands of dollars.

There are situations where variable annuities can make sense, particularly if you have maxed out all tax-advantaged accounts and want additional tax-deferred growth with a guaranteed income floor. But for most investors, a combination of low-cost index funds and a simple MYGA or fixed annuity will deliver better results at a fraction of the cost.

Frequently Asked Questions

Is an annuity safer than a mutual fund?

A fixed annuity or MYGA is safer in the sense that your principal is guaranteed by the issuing insurance company and backed by your state’s guaranty association. Your balance will never decline due to market conditions. A mutual fund has no such guarantee. However, “safer” depends on context. If inflation runs higher than your annuity rate, your purchasing power still erodes. And if you need to withdraw early, surrender charges can reduce your return.

Should I move my 401(k) into an annuity when I retire?

It depends on your income needs and risk tolerance. Rolling part of a 401(k) into a MYGA or income annuity can make sense if you want guaranteed returns or lifetime income. But rolling the entire balance into an annuity sacrifices growth potential and liquidity. Most planners suggest allocating 30%-50% of retirement savings to guaranteed products and keeping the rest in diversified mutual funds or ETFs.

Do annuities have higher fees than mutual funds?

Not always. MYGAs and fixed annuities have no explicit annual fees. Variable annuities, however, commonly charge 2.0% to 3.5% per year in combined fees, which is substantially higher than a low-cost index fund at 0.03%-0.10%. The type of annuity matters enormously when comparing costs.

Can I lose money in a fixed annuity?

You will not lose principal in a fixed annuity due to market fluctuations. The only scenarios where you could receive less than you deposited are if you surrender the contract early and pay surrender charges, or if the issuing insurance company becomes insolvent (which is extremely rare among A-rated carriers and is partially protected by state guaranty associations).

What is the best age to buy an annuity?

Most financial planners suggest considering annuities starting around age 55 to 65, when the focus shifts from accumulation to preservation and income planning. MYGAs can make sense even earlier as a bond alternative. Income annuities (SPIAs) generally offer better payout rates the older you are when you purchase them, since the insurer expects to make payments over a shorter period.
