With a fixed annuity, the insurance company assumes the investment risk. Once you fund the contract, the insurer guarantees both your principal and a minimum interest rate, and it must credit those amounts to your account no matter how its own investments perform.1FINRA.org. Annuities – Investment Products You are shielded from market losses. You still carry other risks, though, and knowing where the line falls is the whole point of understanding this product.
How the Insurer Absorbs the Investment Risk
When you buy a fixed annuity, the insurer commits to crediting your account at a guaranteed rate. If the company’s own portfolio earns less than that promised rate, the insurer covers the shortfall out of its own capital. Your contract value stays the same whether the stock market drops 30% or bond yields collapse.1FINRA.org. Annuities – Investment Products
The insurer manages that obligation through its general account, a consolidated fund used to back the guarantees made to every policyholder. Premiums are typically invested in conservative holdings such as investment-grade corporate bonds and government-backed securities. Because the insurer holds legal title to those assets, the company is the one exposed to bond defaults, interest rate swings, and credit downgrades inside the portfolio. Your balance is insulated from those internal gains and losses.
The transfer runs one direction. If the insurer’s investments outperform the guaranteed rate, the company keeps the excess as profit. If they underperform, the insurer eats the loss. That asymmetry is what separates a fixed annuity from owning stocks, mutual funds, or any other product where your account balance moves with the market.
What the Insurer Actually Guarantees
Two contractual promises sit at the core of a fixed annuity:
- A minimum guaranteed interest rate. Every fixed annuity contract specifies a floor rate the insurer must credit regardless of economic conditions. The exact rate varies by contract and insurer. Some policies guarantee rates below 1%; others set the floor higher. The rate is locked into your contract at purchase and cannot be reduced later.
- Principal protection. Your account balance will not fall below the total premiums you have contributed, minus any withdrawals you have taken. In a recession that might cost a stock portfolio 20% or more, your fixed annuity balance holds steady.
Beyond the floor, most fixed annuities also credit a higher “declared” or “current” rate that the insurer resets periodically, often annually. That declared rate can move up or down over time, but it can never drop below the contractual minimum.
A Multi-Year Guaranteed Annuity (MYGA) works a little differently. It locks in a specific rate for the entire contract term, commonly three, five, or seven years, the way a bank CD locks a rate for its full term. When the MYGA term ends, you can renew at a new rate, withdraw the funds, or roll the balance into another product.
Fixed vs. Variable: Who Bears Risk in Each
The clearest way to see who bears risk in a fixed annuity is to hold it next to a variable annuity. In a fixed annuity, the insurer guarantees both the rate of return and the payout amount. In a variable annuity, your money goes into investment subaccounts that behave like mutual funds, and your balance rises and falls with market performance. You can lose money in a variable annuity, and there is no guarantee you will earn any return at all.1FINRA.org. Annuities – Investment Products
It comes down to one question: who is exposed if investments perform poorly? In a fixed annuity, the insurer. In a variable annuity, you. Fixed annuities trade lower potential returns for predictability. Variable annuities offer more growth potential and accept the possibility of loss.
Risks That Still Fall on You
Investment risk is off your plate. Several other financial risks stay with you.
Inflation
A fixed annuity pays a set interest rate, which does not adjust when inflation rises. If your annuity credits 3% and inflation runs at 4%, your money loses real purchasing power each year. Over a long retirement, that erosion can meaningfully reduce what your annuity payments actually buy. This is the price of certainty. You are protected from downturns, and you are also locked out of the higher returns that might have kept pace with rising prices.
Surrender Charges and Liquidity
Most fixed annuities impose surrender charges if you pull out more than a specified amount during the early years of the contract. A common structure uses a declining scale: roughly 7% to 8% in the first year, dropping by about a percentage point each year until it reaches zero, often over six to ten years. Many contracts let you withdraw up to 10% of your account value each year without triggering a charge, but anything above that free-withdrawal amount will be penalized.
Your money is not fully liquid during the surrender period. If a large unexpected expense forces you to tap the annuity early, you can lose a real slice of your balance. Before buying a fixed annuity, make sure you have enough liquid savings elsewhere to handle emergencies without touching the contract.
Market Value Adjustments
Some fixed annuity contracts include a market value adjustment (MVA) clause that applies if you surrender before a specified date. If interest rates have risen since you purchased the annuity, the MVA can reduce your surrender value. If rates have fallen, it can increase it.2Interstate Insurance Product Regulation Commission. Additional Standards for Market Value Adjustment Feature for Modified Guaranteed Annuities and Index-Linked Variable Annuities This is a nuance to the principal protection guarantee: your account balance cannot decline due to market losses during the accumulation period, but an MVA applied at early surrender can bring the amount you actually receive below what you might expect. Check your contract for the MVA formula and the dates it applies.
Tax Penalties on Early Withdrawal
If you withdraw any taxable amount from an annuity before age 59½, the IRS adds a 10% penalty tax on top of regular income tax.3Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Combined with surrender charges, an early withdrawal can be an expensive mistake. Exceptions apply for death, disability, substantially equal periodic payments, and immediate annuities.
Insurer Default
The insurer’s promise is the foundation of the whole product. If the insurance company becomes insolvent, that promise is at risk. State guaranty associations provide a safety net, but the net has limits, and the strength of the company matters at least as much as the rate on the contract.
How to Confirm the Insurer Can Actually Pay
Because the guarantee is only as good as the company behind it, evaluating financial strength before you buy is one of the most important protective steps you can take.
Independent rating agencies grade each insurer’s ability to meet its policy obligations. AM Best, the most widely referenced, assigns Financial Strength Ratings on a scale from A++ (Superior) down to D (Poor); a rating of A or higher indicates excellent or superior ability to meet obligations.4AM Best. Guide to Best’s Financial Strength Ratings Moody’s, S&P Global, and Fitch also rate insurers, and comparing across agencies gives a fuller picture. Look for a consistent track record of high ratings over several years, ideally through past recessions.
Regulation reinforces the ratings. Every state requires insurers to hold minimum reserves calculated under standards set by the National Association of Insurance Commissioners.5National Association of Insurance Commissioners. 2026 Edition – Valuation Manual Risk-Based Capital formulas require additional capital based on the risks in each company’s specific mix of assets and liabilities, and regulators can intervene when capital drops below required levels.6NAIC.

If a company still fails, every state, along with Puerto Rico and the District of Columbia, runs a guaranty association that steps in to continue coverage and pay claims using the failed company’s remaining assets plus assessments collected from other insurers in the state. Coverage limits vary. Most states cap annuity protection at $250,000 per contract, while several set higher limits of $300,000, $410,000, or up to $500,000.7NOLHGA. How You’re Protected If you plan to hold a large balance, spreading it across multiple insurers can keep the full amount within guaranty association limits in each state.
