Market-linked growth with principal protection. How crediting methods work, current rates, and how to compare FIAs across 10+ appointed carriers.
Last reviewed September 2026 by Dev Gaymes, Texas-licensed life insurance agent, NPN 16654074 · Editorial policy
A fixed index annuity (FIA) is an insurance contract that credits interest based on the performance of a market index - like the S&P 500, while protecting your principal from market losses. When the index goes up, you earn a portion of the gain. When the index goes down, you earn 0%, not a loss. Your principal and all previously credited gains are locked in permanently. Earnings grow tax-deferred until withdrawal. In 2026, FIAs offer cap rates up to 10.75% and participation rates exceeding 140%, making them one of the most compelling options for retirement savers who want growth potential without market risk.
The defining feature of every FIA is the 0% floor. In any crediting period where the linked index has a negative return, even a catastrophic crash. Your account value stays exactly the same. You earn zero, but you lose zero. Then each year's gains are "locked in" and can never be taken away by future market declines. This is the fundamental trade-off: you give up some upside (through caps and participation rates) in exchange for guaranteed downside protection.
Hypothetical example. Cap limits gains in strong markets; floor protects principal in down markets. Actual rates vary by carrier and crediting method.
Every FIA uses one or more methods to determine how much index gain is credited to your account. Understanding these is the key to comparing products:
The maximum interest your annuity can earn in a crediting period. If the index exceeds the cap, your credit is limited to the cap. If the index is below the cap, you earn the full index return.
2026 range: 5%–10.75%
The percentage of the index gain credited to your annuity. Often paired with uncapped strategies or volatility-controlled indexes.
2026 range: 40%–140%+
A fixed percentage subtracted from the index gain before crediting. If the remainder is positive, you earn interest. If negative, you earn 0%.
2026 range: 1%–4%
Carriers can adjust caps, participation rates, and spreads at each renewal period based on economic conditions. However, they cannot retroactively change gains already credited. When comparing FIAs, look at the carrier's history of maintaining competitive rates over time, not just the initial teaser rate.

Many FIAs offer guaranteed lifetime income riders for an additional annual fee (typically 0.75%–1.25% of the income base). These riders guarantee a monthly or annual income stream you cannot outlive, regardless of account value. The income base often grows at a guaranteed rate (5%–7%) during deferral, separate from the index crediting on your accumulation value. Income riders are ideal if your primary goal is retirement income rather than accumulation.
Accumulation value vs. income base: Your accumulation value is what you'd receive if you surrendered the annuity. It grows based on index crediting. Your income base (if you add an income rider) is a separate calculation used only to determine your guaranteed income payments. They are not the same number. An independent broker can show you illustrations for both.
Illustrative examples. The scenarios below are for illustration only and do not represent any specific client. Figures are hypothetical and are not a quote, an offer of coverage, or a prediction of results. Actual outcomes depend on age, health, carrier underwriting, and the terms of the issued policy.
The Nguyens wanted to keep their retirement savings growing but were nervous about another market downturn within 10 years of retirement. Their financial advisor had them in a balanced fund charging 1.2% in fees.
We placed $200K into a 7-year FIA with a 9.5% S&P 500 cap rate and a 0% floor via a 1035 exchange, which is generally tax-free, from their old annuity. No annual management fees on the base contract. In a year the S&P gains 12%, they earn 9.5%. In a year it drops 20%, they earn 0% and lose nothing. After 7 years, their gains are locked in and they can renew, annuitize, or roll to another product.
Gloria wanted to guarantee she'd never run out of money in retirement. She'd seen her parents struggle with depleted savings in their 80s and wanted a pension-like income stream starting at 67.
We placed her in a $150K FIA with a lifetime income rider that grows her income base at 7% simple interest during the 5-year deferral period. At 67, her guaranteed income base will be approximately $202,500, providing ~$12,150/year ($1,013/month) for life regardless of market performance. Her accumulation value continues to grow based on index crediting and passes to her beneficiary generally income-tax-free at death.
Richard had $100K in bank CDs earning 4% and was paying taxes on the interest annually, netting about 2.7% after taxes in his bracket. He wanted to do better without risking principal.
We moved $100K into a 5-year FIA with a 8.5% cap on the S&P 500. His gains now grow tax-deferred (no annual tax drag), and in years where the S&P performs well, he can earn up to 8.5% instead of the flat 4%. In flat or down years, he earns 0% but never loses. He retains 10% annual free withdrawal access.
This is where most FIA decisions are actually made, and where most illustrations are least useful. A crediting strategy determines how index movement becomes interest in your contract. Two products tracking the same index can credit very differently.
General mechanics. Products combine these differently and terms vary by carrier and contract.
Annual point-to-point is the most common structure: the index value is recorded on your contract anniversary, compared to the prior year, and interest credited accordingly. Monthly and multi-year structures exist and behave differently in volatile markets.
What matters is that the lock is automatic. Once interest is credited, it is locked in and the next period starts from the new value. A market decline afterward does not claw it back. That annual reset is the feature doing most of the work in an FIA, not the index selection.
Are the cap and participation rate guaranteed, and for how long?
Most FIAs set these annually and the carrier can change them within contractual minimums. An attractive first-year rate can fall in year two. Ask for the guaranteed minimum cap and participation rate written into the contract, not the current declared rate - that minimum is what you actually own.
This is the specific problem these products are built for, and it is worth understanding rather than taking on faith.
Two retirees can earn the same average return and end up in completely different places, depending on the order the returns arrive. Someone drawing income from a portfolio that falls 20% in their first two years is selling assets at depressed prices to fund withdrawals, and the portfolio may never recover even if later returns are strong.
A 0% floor removes the down years from the sequence. You give up the strong years above the cap in exchange - that is the trade, and it is a real one. More on how the math works.
The 8% cap in the example above is a current rate for one crediting period. It is not locked in for the life of the contract.
Carriers set caps, participation rates and spreads at the start of each crediting period and can adjust them on renewal, subject to a guaranteed minimum written into the contract. That minimum is the number that actually binds them. The current rate is what they are offering today.
An FIA is a long-term contract, and withdrawing more than the free amount during the surrender period costs you. A typical 10-year schedule declines each year:
Illustrative only. Surrender schedules vary widely by carrier and product, some run 5 years, some 14. A market value adjustment may apply in addition. Your contract governs.
Most contracts allow a free withdrawal, commonly around 10% of contract value each year after the first, without a surrender charge. Many also waive charges entirely for qualifying events such as confinement to a nursing home or terminal illness diagnosis - worth confirming, because those provisions vary and are rarely mentioned in a sales conversation.
The guarantees in an annuity depend on the claims-paying ability of the insurance company that issues it. That makes the insurer’s financial strength the most important safeguard in the whole contract, and the first thing worth checking.
Look at the AM Best rating of the specific company issuing the contract, not just the parent brand, since large groups often issue through several subsidiaries with different ratings. How long the company has been writing annuities, and how it has treated renewal rates on existing contracts, tells you more than any illustration.
Texas law does not allow agents to use state guaranty coverage as a reason to buy an annuity, and you should not choose a carrier based on it. The Texas Department of Insurance can answer questions about how insolvencies are handled.
Print this. Any advisor recommending a specific contract should be able to answer all of it without checking.
That last one is fair to ask anyone, including us. We are paid a commission by the issuing carrier when a contract is placed, disclosed before you apply.
Good fit: Pre-retirees and retirees (ages 50–75) who want growth above CDs/MYGAs, principal protection, tax-deferred compounding, and optional lifetime income. Also suitable for conservative investors who've been burned by market losses and want to participate in gains without the risk.
Not a fit: Anyone needing full liquidity within 5 years, aggressive investors wanting maximum market exposure, or people uncomfortable with multi-year surrender schedules. If you need your money accessible at all times, a MYGA or high-yield savings account is a better fit.
For most Dallas retirees, a fixed index annuity is a tool for one slice of savings: money that needs a floor, or money you want turned into income you cannot outlive. It is rarely the right home for everything. The useful questions are how much of your savings needs protection from a loss at the wrong moment, and when you will need it.
Three Texas factors change the arithmetic. Texas has no state income tax, so tax deferral is worth less here than in many states. An annuity with a named beneficiary generally passes outside probate. And because Texas is a community property state, an annuity bought with marital funds is typically community property, which matters if you name a beneficiary other than your spouse.

A fixed index annuity (FIA) is an insurance contract that credits interest based on the performance of a market index like the S&P 500, while protecting your principal from market losses. When the index goes up, you earn a portion of the gain (subject to a cap, participation rate, or spread). When the index goes down, you earn 0%, not a loss. Your principal and all previously credited gains are locked in and cannot be taken away. Earnings grow tax-deferred.
Returns depend on the crediting method and market performance. In 2026, typical cap rates range from 5% to 10.75%, participation rates from 40% to 140%+, and spreads from 1% to 4%. Over multi-year horizons, FIAs have historically averaged 3% to 7% annually after caps and spreads, compared to 4% to 5.5% for MYGAs. The key advantage is that you never lose principal in a down market.
A cap rate is the maximum interest a fixed index annuity can earn in a given crediting period. For example, if your cap is 8% and the S&P 500 gains 15%, you earn 8%. If the index gains only 5%, you earn 5%. If the index drops, you earn 0%. As of February 2026, top cap rates range from 8% to 10.75% depending on carrier and term length.
A participation rate determines what percentage of the index gain is credited to your annuity. If the participation rate is 60% and the index gains 10%, you earn 6%. Participation rates currently range from 40% to over 140% depending on the index and carrier. Higher participation rates are often paired with volatility-controlled indexes.
You cannot lose money due to market declines - FIAs have a 0% floor, meaning the worst crediting you receive in a down market is 0%. However, you can lose value through early surrender charges (typically in the first 5-10 years), excess withdrawals beyond the 10% free annual allowance, or optional rider fees that reduce cash value. Principal protection only applies if you hold the contract through the surrender period.
A MYGA (multi-year guaranteed annuity) pays a fixed interest rate for a set period - like a CD inside an annuity. An FIA's interest is tied to an index and varies year to year, with potential for higher returns in strong markets. MYGAs offer certainty; FIAs offer upside potential with downside protection. Both grow tax-deferred. In 2026, MYGAs pay 4%-5.5% guaranteed, while FIAs have earned 3%-7% historically depending on market conditions.
Surrender charges are fees for withdrawing more than the free annual allowance (typically 10%) during the surrender period (usually 5-10 years). Charges start high (8%-10%) and decrease annually until reaching 0%. Most FIAs allow 10% penalty-free withdrawals each year after year one. Before age 59½, IRS penalties may also apply.
FIAs are ideal for pre-retirees and retirees (typically ages 50-75) who want growth potential above CDs and MYGAs, principal protection from market losses, tax-deferred compounding, and optional guaranteed lifetime income riders. FIAs are not ideal for those needing full liquidity, wanting maximum market returns, or with a short time horizon under 5 years.
What an annuity is. Annuities are long-term insurance products designed for retirement income, not short-term savings vehicles and not investments in the stock market. A fixed index annuity is a fixed insurance product issued by an insurance company. It is not a security, and it is not FDIC insured, not bank guaranteed, and not a deposit of, or guaranteed by, any bank or credit union.
Guarantees. All guarantees, including any floor, minimum value, or income benefit, are backed solely by the financial strength and claims-paying ability of the issuing insurance company. They are not guaranteed by DG Life Group, by any broker, or by any government agency.
You do not own the index. With a fixed index annuity you are not buying shares of any index, stock, or fund. Interest is credited according to a formula tied to an index's performance. Index crediting typically excludes dividends, so returns will not match the total return of the index itself. Caps, participation rates, and spreads limit the interest credited, and the carrier can generally change them on future crediting periods, subject to contractual minimums.
Access to your money. Surrender charges apply during a surrender period that commonly runs several years, and a market value adjustment may also apply. Withdrawals reduce the contract value, any death benefit, and any income benefit. Withdrawals of taxable amounts are subject to ordinary income tax, and withdrawals taken before age 59½ may incur an additional 10% federal tax penalty. Optional riders, including income riders, usually carry an explicit charge that reduces contract value.

Our obligations to you. Under the NAIC Suitability in Annuity Transactions Model Regulation (Model #275), adopted in nearly every U.S. jurisdiction, a producer recommending an annuity must act in the consumer's best interest and satisfy obligations of care, disclosure, conflict of interest, and documentation. That means a recommendation is based on your financial situation, needs, and objectives; that our role and compensation are disclosed; and that the basis for the recommendation is documented. DG Life Group is compensated by the issuing insurance company through commission when a contract is placed. We will tell you that before you apply, not after.
