A comprehensive guide to annuities for retirement income: how they work, all types explained (MYGA, FIA, SPIA, variable, DIA), full cost breakdown, and a framework for deciding whether an annuity belongs in your retirement plan.
How They Work, Which Types Exist, What They Cost, and Whether One Belongs in Your Retirement Plan
By the Retirement Rescue Editorial Team | Financial Content Reviewed for Accuracy — Last Updated May 2026
If you are within 10 years of retirement — or already there — you have likely heard the word "annuity" more times than you can count. Financial advisors recommend them. Insurance companies market them aggressively. And skeptics warn you to avoid them entirely.
The truth, as is usually the case with financial products, sits somewhere in the middle. An annuity is not inherently a good or bad instrument. It is a specialized tool that solves a specific set of retirement problems efficiently — and others poorly.
This guide covers everything you need to make an informed decision: what annuities are, how different types work mechanically, what they cost (all of it, including the fees that do not appear on the front page), and the specific situations where an annuity may strengthen a retirement income plan — and where it may not.
This is not a ranked list of products. It is an education-first guide designed to help you understand annuities thoroughly enough to ask the right questions of any advisor or insurance company you speak with.

An annuity is a contract between you and an insurance company. You transfer a lump sum — or a series of payments — to the insurer, and in return, the insurer promises to pay you a stream of income, either immediately or at a future date, often for the rest of your life.
The core value proposition is direct: you give up liquidity and control of a sum of money in exchange for certainty about future income.
That trade-off is the defining characteristic of every annuity, regardless of type. Whether you are looking at a simple fixed annuity or a complex variable product with optional riders, the fundamental structure is the same: you transfer risk to the insurer; the insurer charges a margin for accepting it.
Key terms you will encounter throughout this guide:
Annuities function differently depending on their type, but they share a common underlying mechanism: the insurance company pools your premium with premiums from thousands of other contract holders, invests that capital, and earns a spread between what the portfolio returns and what it promises to pay you.
This spread — the insurer's margin — is how the company profits, funds administrative costs, pays sales commissions, and finances its guaranteed benefit obligations.
The guarantee engine. Insurance companies can promise lifetime income because they underwrite longevity risk across a large population. If you live to 97, the insurer pays. If you die at 71, the remaining account value may revert to the insurer (unless a death benefit rider has been added). This pooling of risk is similar to how life insurance works in reverse.
Tax treatment. Annuities grow tax-deferred. You do not owe taxes on gains until you take withdrawals. When you do withdraw:
Understanding annuity types is the most important step before evaluating any specific product. The differences in risk, return potential, fees, and flexibility vary dramatically across categories.
A fixed annuity credits your account with a guaranteed interest rate for a set period — typically 3, 5, or 7 years — similar to a bank certificate of deposit but with tax-deferred growth and insurance company guarantees.
How it works: You deposit a premium. The insurer credits a fixed rate annually. At the end of the guarantee period, you may renew at the then-current rate, annuitize, or roll the funds to another product without penalty.
Best suited for: Retirees or near-retirees seeking predictable, conservative growth with principal protection and no market exposure.
Key consideration: After the initial guarantee period expires, renewal rates reset to current market rates — which may be lower. Review an insurer's renewal rate history before committing.
A MYGA is a specific type of fixed annuity that locks in a guaranteed interest rate for the full surrender period — typically 3 to 10 years.
How it works: You deposit a lump sum. The insurer guarantees a stated annual rate for the full contract term. At maturity, you receive your full principal plus all credited interest. There is no renewal-rate uncertainty during the guarantee period.
Rate context: MYGA rates in 2026 have remained competitive with medium-term Treasury yields. Five-year products from financially strong insurers have generally offered rates in the 4.5% to 5.5% range depending on premium size, insurer, and state.
Best suited for: Savers who want a CD-like product with tax deferral, full principal protection, and a known terminal value. Particularly relevant for near-retirees holding cash in low-yield savings who want certainty without market exposure.

A fixed index annuity links credited interest to the performance of a market index — commonly the S&P 500 — but protects your principal from market losses through a floor guarantee, typically set at 0%.
How it works: Each contract year, the insurer measures index performance and credits interest based on one of three crediting methods:
Best suited for: Retirees who want principal protection with more upside potential than a straight fixed annuity, without direct equity market exposure. The trade-off relative to owning index funds outright is compressed upside.

A variable annuity invests your premium in sub-accounts — functionally similar to mutual funds — so your account value rises and falls with the markets. There is no principal protection in a basic variable annuity.
How it works: You choose from a menu of sub-accounts. Account value fluctuates daily with those sub-accounts. Optional guaranteed income riders can provide an income floor even if the account value declines to zero.
Key risk: Variable annuities carry full market downside risk in the base contract. Guaranteed income features come from optional riders that add 0.75% to 1.50% in annual costs on top of base contract fees.
Best suited for: Investors who want tax-deferred market-rate growth combined with an eventual guaranteed income guarantee, and who can tolerate account value fluctuation.
A Single Premium Immediate Annuity converts a lump sum into income payments that begin within 30 days to 12 months of purchase.
How it works: You pay the insurer a single premium. The insurer calculates a monthly payment based on your age, premium amount, prevailing interest rates, and the payout option you choose. Payments begin immediately.
Payout options:
Best suited for: Retirees who want to convert a portion of savings into a guaranteed pension-like income stream to cover fixed essential expenses.
A deferred income annuity functions like a SPIA but with a delayed start date. You purchase the contract today and income begins at a future age — often 80, 82, or 85.
How it works: By delaying income for 10 to 25 years, actuarial mortality credits compound over the deferral period, producing substantially higher monthly payments than a SPIA would provide for the same premium.
Best suited for: Retirees who want to insure against longevity tail risk — outliving other assets — at a relatively low upfront cost.
QLAC note: DIAs held in IRAs must comply with Qualified Longevity Annuity Contract rules. QLAC premiums are currently limited to the lesser of $200,000 or 25% of the IRA balance, and funds in a QLAC are excluded from RMD calculations until income begins.
Longevity protection. Annuities are the only financial product that can guarantee income for as long as you live, regardless of market performance. A portfolio withdrawal strategy carries the risk of depletion. A properly structured income annuity does not.
Tax-deferred growth. In non-qualified accounts, annuity gains defer taxation until withdrawal — advantageous in high-income accumulation years relative to taxable accounts.
Principal protection (fixed and FIA products). Fixed and index annuities guarantee principal against market loss — relevant for retirees with limited ability to recover from a significant drawdown.
Rate certainty (MYGAs). Multi-year guaranteed annuities lock in rates for the full contract term, eliminating reinvestment risk.
Customization via riders. Guaranteed lifetime withdrawal benefits, enhanced death benefits, cost-of-living adjustments, and long-term care accelerators can be layered onto a contract at additional cost.
Surrender charges. Most deferred annuities impose charges for withdrawals above the free withdrawal allowance during the surrender period — typically starting at 7%–10% in year one and declining to zero by contract end.
Liquidity constraints. Once premium is committed, access is restricted. Most contracts permit annual free withdrawals of 10% of account value, but meaningful liquidity beyond that is limited.
Complexity. Variable and FIA products in particular require careful comparison of caps, spreads, participation rates, rider mechanics, and renewal provisions.
Fee drag (variable annuities). All-in costs on variable annuity products — mortality and expense charges, sub-account expense ratios, and rider fees — may reach 2.5% to 3.5% annually.
Inflation risk. Fixed monthly payments from a SPIA or MYGA lose purchasing power over a 20- to 30-year retirement. Inflation-indexed SPIAs deliver materially lower initial payments.
Counterparty risk. Annuities are backed by the issuing insurer, not the FDIC. State guaranty associations typically cover up to $250,000 per insurer per contract type, but limits vary by state.
The relevant question is not whether annuities are good or bad. It is whether a specific type of annuity addresses an identifiable problem in your retirement plan.
Income gap analysis. Calculate your guaranteed income — Social Security plus any pension — versus your fixed monthly expenses. A meaningful gap is one of the clearest indicators that an income annuity may be worth evaluating seriously.
Liquidity assessment. Confirm you have at least 12 to 24 months of expenses in accessible accounts, plus reserves for healthcare and unplanned needs, before allocating significantly to an annuity.
Insurer financial strength. Purchase only from insurers with AM Best A- or better, Moody's A3 or better, S&P A- or better. Verify ratings at ambest.com — not in marketing materials.
Benchmark against alternatives. A MYGA at 5.0% competes directly with 5-year Treasuries. An income annuity payout should be benchmarked against systematic withdrawal rates from a comparable portfolio, adjusted for the longevity guarantee the portfolio strategy cannot provide.
Read the contract. Surrender schedules, renewal rate floors, cap rate minimums, and benefit base mechanics are in the contract. Do not commit based on a sales illustration alone.
Step 1: Define the problem. Longevity protection? Safe accumulation? Guaranteed income to cover fixed expenses? The answer determines which type of annuity — if any — is relevant.
Step 2: Determine the budget. Common guidance suggests no more than 25%–40% of investable assets allocated to annuities, preserving meaningful liquidity. Individual circumstances determine the right amount.
Step 3: Obtain competing quotes from multiple carriers. Compare at minimum three to five carriers using an independent agent or quoting platform.
Step 4: Verify financial strength ratings. Check AM Best, Moody's, and S&P directly for each carrier under consideration.
Step 5: Use the free-look period. All states require a free-look period — typically 10 to 30 days after contract delivery — during which you may return the contract for a full refund. Read the full contract before this window closes.
Step 6: Consult a fee-only fiduciary. Commission-based agents are compensated on the sale. An independent fiduciary review before committing a significant sum is worthwhile.
Buying based on the illustration, not the contract. Illustrations show hypothetical scenarios — often optimistic. The contract language governs what the insurer actually owes you.
Ignoring the surrender period relative to your timeline. A 10-year surrender schedule on a 76-year-old is a meaningful liquidity constraint during a period when healthcare costs can spike unpredictably.
Over-allocating. Committing too large a share of savings when near-term liquidity needs are uncertain is among the most common errors.
Conflating "guaranteed" with "risk-free." Annuity guarantees are backed by insurer solvency and state guaranty funds — highly reliable for strong carriers, but not without counterparty risk.
Buying a complex product to solve a simple problem. A MYGA addresses safe accumulation cleanly. A variable annuity with stacked riders for the same purpose adds fee drag and complexity without proportionate benefit.
Overlooking the 1035 exchange. If you hold an existing life insurance policy or deferred annuity with accumulated value, a 1035 exchange allows a tax-free transfer to a new contract. This option is frequently overlooked in new purchase discussions.
| Annuity Type | Cost Structure | Approximate Annual Cost |
|---|---|---|
| Fixed / MYGA | Spread built into credited rate | ~0% explicit; margin embedded |
| Fixed Index Annuity (no riders) | Option hedging costs via cap/spread | ~0% explicit; margin embedded |
| Fixed Index Annuity (with income rider) | Rider fee on benefit base | 0.75%–1.50% per year |
| Variable Annuity | M&E + sub-account expenses + rider fees | 1.50%–3.50% all-in annually |
| SPIA / DIA | Mortality loading in payout rate | ~0% explicit; actuarial margin embedded |
No annuity is free. Fixed and MYGA products earn insurer margin from the spread between portfolio returns and credited rates. FIAs earn margin through option hedging costs embedded in the cap and spread structure. These costs are real — they are simply not labeled as fee line items on a statement.
Commission disclosure. Annuity agents typically earn commissions of 3%–7% of premium, funded by the insurer. You do not pay this directly — it is absorbed into product pricing — but the incentive structure warrants awareness.
Rider costs. Income rider fees of 0.75%–1.50% annually on the benefit base compound as a meaningful drag on account value. On a $300,000 benefit base at 1.0%, that is $3,000 per year regardless of account performance.
What is the safest type of annuity?
Fixed annuities and MYGAs carry the lowest risk profile: principal is contractually guaranteed, the interest rate is fixed, and there is no market exposure. They are backed by the insurer's general account and state guaranty associations.
Can I lose money in an annuity?
In fixed and MYGA annuities, principal is protected. In FIAs, the 0% floor prevents index-driven losses, though surrender charges during the surrender period reduce net accessible value. Variable annuities carry full market downside risk.
Are annuities taxed?
Yes. Growth is tax-deferred, not tax-free. Non-qualified annuity gains are taxed as ordinary income upon withdrawal. Qualified annuities held in IRAs are fully taxable on withdrawal and subject to RMDs beginning at age 73.
What happens to an annuity when you die?
Depends on the contract and payout option. Life-only SPIAs end at death. Deferred annuities with death benefit provisions pass value to named beneficiaries outside probate.
What does it cost to exit an annuity early?
Surrender charges apply during the surrender period — typically 7%–10% in year one, declining to zero by contract end. Most contracts permit 10% annual free withdrawals. After the surrender period, funds may be accessed without penalty.
What is a guaranteed withdrawal benefit (GLWB) rider?
A GLWB rider guarantees the ability to withdraw a set percentage of a benefit base annually for life, regardless of actual account value. The benefit base typically grows at a guaranteed rate during the deferral period.
What is a 1035 exchange?
A tax-free transfer of accumulated value from one life insurance policy or annuity to a new contract under IRS Section 1035. Preserves tax deferral without triggering a taxable event. Rules apply — consult a tax professional.
Is my annuity protected if the insurance company fails?
State guaranty associations provide coverage — typically up to $250,000 per insurer per contract type, with limits varying by state. This is not equivalent to FDIC insurance. Financial strength ratings matter.
What is the minimum amount needed to buy an annuity?
MYGAs commonly start at $10,000–$50,000. SPIAs typically require $50,000–$100,000. Variable annuities may accept smaller premiums but are generally used for larger sums.
Should I put my IRA into an annuity?
Permissible, but the annuity's tax deferral benefit is redundant inside an IRA. The decision should rest on the income guarantee features, not tax considerations.
What is the difference between an annuity and a pension?
A pension is employer-funded: you receive income for life without contributing premium. An annuity is self-funded: you provide the premium and the insurer provides the income guarantee. A SPIA functions similarly to a pension in its payment mechanics.
How do I compare annuity income payouts across carriers?
Request quotes per $100,000 of premium across multiple carriers using the same age, sex, and payout option. Compare monthly income, insurer AM Best rating, and — for riders — compare benefit base growth rate, withdrawal percentage, and rider cost.
Can I add money to an annuity after purchase?
Flexible premium annuities accept additional contributions. Single premium contracts accept one lump sum only.
What is a fixed index annuity cap rate and can it change?
The cap rate limits how much index gain is credited per period. Caps are set by the insurer at each renewal and can change — subject to a contractual minimum, often 1%–2%. Historical cap rates offered by an insurer are meaningful due-diligence data.
At what age does it make sense to consider an annuity?
There is no universal answer. Income annuities are generally most efficient at or near retirement — ages 65 to 72 — as mortality credits become more significant. Deferred income annuities can be purchased earlier as longevity insurance. MYGAs are relevant at any age where principal protection and tax deferral are the objectives.
Annuities are a specialized retirement income tool — not a universal solution. They address specific problems efficiently and others poorly.
They may provide real value when: there is a meaningful income gap between guaranteed income and fixed expenses; principal protection during the retirement transition is a priority; or longevity tail risk warrants dedicated insurance.
They provide limited value when: near-term liquidity needs are significant; a well-funded diversified portfolio can self-insure longevity risk; or simpler, lower-cost products achieve the same objective without the contractual constraints.
The most effective use tends to be bounded: allocating a specific tranche of savings to guaranteed income while keeping the remainder in a diversified, liquid portfolio. The combination — covering essential expenses with guaranteed income and funding discretionary spending from the portfolio — reduces sequence-of-returns risk while preserving flexibility.
If you want to understand where annuities might fit in your specific retirement plan, start with your income gap analysis, your liquidity reserve, and a clear definition of the problem you are trying to solve — before any product conversation begins.
