What is an annuity? Fixed vs. variable
Key takeaways
- Annuity: A long-term contract with an insurance company designed to convert a lump sum or series of payments into a steady stream of future income.
- Fixed annuities: Guarantee a minimum interest rate with zero market risk, making them highly predictable. They are regulated by state insurance commissioners.
- Variable annuities: Tie returns directly to underlying investment options (like mutual funds). They offer growth potential but carry investment risk and are regulated by the SEC and FINRA.
- Tax treatment: Growth is tax-deferred, but withdrawals are taxed at ordinary income rates rather than the lower capital gains rate. Early withdrawals before age 59½ may trigger a 10% IRS penalty.
- Costs: Fees and surrender charges can heavily impact returns. Variable annuities are notoriously expensive, with all-in annual costs frequently ranging between 2% and 3%.
At some point in retirement planning, the question shifts from how to accumulate assets to how to make those assets last. An annuity is one of the financial products designed to address that question.
It does not belong in the same category as a savings account or a mutual fund. It is an insurance contract, and understanding what that distinction means in practice is the first step to evaluating whether one belongs in a retirement portfolio.
The mechanics of an annuity
The core concept is simple: the account holder pays an insurance company (either a one-time lump sum or through ongoing contributions), and the insurer promises to pay it back to them in periodic payments, starting immediately or at a future date.
Every annuity contract moves through two distinct phases:
- The accumulation phase: The period where the funded money sits with the insurer and grows according to the contract’s terms.
- The annuity (payout) phase: The period where the insurer begins making regular distributions to the account holder. These payouts can be structured for a fixed number of years, their lifetime, or the joint lifetimes of them and their spouse.
Annuities are also categorized by when those payouts start. An immediate annuity begins distributions shortly after purchase (typically within a year). A deferred annuity allows money to accumulate over a longer time horizon before payouts are triggered. It is within the deferred structure that the choice between fixed and variable options matters most.

Fixed annuities: Predictability & income for life
Under a fixed annuity structure, the insurance company guarantees a minimum rate of interest during the accumulation phase and guarantees that the account holder’s future periodic payouts will be a specific, predictable amount.
The defining characteristic here is safety. They know their rate of return in advance, and it never fluctuates with market conditions. The insurance company absorbs 100% of the investment risk. Because fixed annuities do not involve underlying securities, they are regulated at the state level by state insurance commissioners.
Fixed annuities vs. CDs & government bonds
A common question arises: Why lock money into a fixed annuity when the account holder could just buy a Certificate of Deposit (CD) or a government bond? While CDs and bonds offer similar low-risk, predictable returns, a fixed annuity provides two distinct advantages:
- Guaranteed lifetime income: CDs and bonds eventually mature and stop paying out. A fixed annuity can be structured to provide a guaranteed income stream they cannot outlive, shifting the longevity risk to the insurance company.
- Tax deferral: Interest from standard CDs and bonds is taxable in the year it is earned. Fixed annuity earnings grow entirely tax-deferred until they begin making withdrawals.
A middle ground: Fixed indexed annuities (FIAs)
The SEC also notes a hybrid category called the Fixed Indexed Annuity (FIA). An FIA links the account holder’s interest credits to the performance of a market index (like the S&P 500) but guarantees that the interest rate will never fall below 0%. This ensures they cannot lose their principal due to market drops.
However, in exchange for this protection, their upside is limited by caps, participation rates, or fee spreads. Because of the built-in floor guarantee against loss, the SEC does not regulate FIAs as securities.
Variable annuities: Growth potential & market risk
A variable annuity is fundamentally different because it is both an insurance contract and a security. Because it contains investment components, it is strictly regulated by federal entities, specifically the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA).
Under this structure, the account holder allocates their funding to a selection of underlying investment options, essentially a menu of mutual funds across various asset classes. The value of their contract fluctuates daily based entirely on the financial performance of those investments.
Unlike a fixed annuity, a variable annuity offers no minimum return guarantee for their investment growth. If the underlying mutual funds experience a market downturn, their contract value drops, and they can lose money.
Variable annuities vs. Direct mutual fund investing
Why pay an insurance company when the account holder could just invest directly in the exact same mutual funds? Direct investing is highly liquid and allows their long-term profits to be taxed at favorable capital gains rates rather than higher ordinary income rates. However, investors choose variable annuities for two specific guardrails:
- Downside living & death benefits: Variable annuities often feature insurance protections that mutual funds lack. For example, a standard death benefit ensures that if the account holder dies before the payout phase begins, their beneficiaries will receive at least the total amount of their initial principal, even if the stock market has crashed.
- Tax-deferred rebalancing: Within a variable annuity, they can move money between different investment funds without triggering capital gains taxes, a benefit they do not get in a standard brokerage account.
What is a rider?
A rider is an optional, specialized amendment attached to an insurance policy that expands or modifies its benefits. In variable annuities, riders are used to customize the account holder’s protection. For instance, an enhanced death benefit rider might lock in their highest historical account value for their heirs, while a guaranteed living benefit rider might ensure a minimum income floor during their retirement regardless of how poorly the stock market performs. Every rider they add comes with an extra fee.
The true cost: Fees & disclosures
While the protections of annuities sound appealing, they come at a high cost. Variable annuities are particularly notorious for their layered fee structures, which generally include:
- Mortality & expense risk (M&E) charges: Fees to cover the insurer’s underlying insurance risks and profit margins.
- Administrative fees: Costs for contract maintenance and recordkeeping.
- Underlying fund expenses: The management fees charged by the internal mutual funds.
- Rider charges: Individual fees are tacked on for each optional benefit the account holder selects.
According to FINRA and SEC investor guidance, when the account holder combines all these individual layers, the all-in annual expenses for a variable annuity typically range from 2% to 3% of the account value. This is vastly more expensive than investing in a standard, low-cost mutual fund or ETF. A contract holder must carefully calculate whether the value of the downside protection outweighs the heavy, cumulative drag these fees place on long-term returns.
How a financial advisor can help
An annuity contract is a long-term, legally binding commitment that weaves together complex state insurance regulations, federal tax codes, investment choices, and rigid fee schedules.
Because variable annuities are classified as securities, any financial professional selling them must be actively registered with FINRA. It is highly recommended to consult a qualified, fiduciary financial advisor to evaluate whether an annuity truly aligns with one’s household income goals or if a simpler, more liquid investment strategy would serve them better.
Frequently Asked Questions
What is a surrender charge and how long does it last?
A surrender charge is a penalty fee imposed by the insurance company if the account holder withdraws money from the annuity before a designated timeline has passed. These charges protect the insurer against early contract cancellations. Surrender periods typically range from 5 to over 10 years, with the penalty percentage gradually decreasing to zero over time. Withdrawing money early can result in losing a significant portion of their principal, completely separate from any additional IRS penalties.
What is the difference between a qualified and a non-qualified annuity?
A qualified annuity is funded in a tax-advantaged account, such as an IRA or 401(k), using pre-tax dollars. Because that money was never taxed, every dollar the account holder withdraws during retirement is fully taxed as ordinary income. A non-qualified annuity is funded with after-tax dollars outside of workplace retirement plans. Since they already paid taxes on their initial principal, only the earnings portion of their future withdrawals is subject to income tax.
What is a 1035 exchange?
Named after Section 1035 of the Internal Revenue Code, this provision allows the account holder to transfer the funds from an existing annuity or life insurance policy directly into a new annuity contract without triggering a tax penalty. The exchange must move directly between the insurance companies. It is crucial to note that the tax-free status only applies in one direction: they can move funds from life insurance to an annuity, or annuity to annuity, but they cannot execute a tax-free 1035 exchange from an annuity back into a life insurance policy.
