If you’ve started researching retirement income options in Tennessee, you’ve probably run into a wall of unfamiliar terms — fixed, indexed, variable, MYGA, SPIA — and wondered whether they’re meaningfully different or just marketing labels. They are genuinely different, and choosing the wrong type for your situation can affect your income for decades. This guide pulls together every major annuity category in one place so you can get your bearings before you ever sit down with a licensed agent.
Start With the Basics: What Is a Fixed Annuity?
A fixed annuity is the simplest form of the contract. An insurance carrier credits a set interest rate to your account for a defined period, and your principal is not exposed to market fluctuation. It tends to appeal to Tennessee retirees who want predictable, steady accumulation without watching a ticker. If you’re new to annuities entirely, this is the logical first stop.
Learn what a fixed annuity is and how it works before comparing it to anything else.
Fixed Index Annuities: Growth Potential Tied to a Market Index
A fixed index annuity (FIA) credits interest based in part on the performance of an external index — such as the S&P 500 — but your account is not directly invested in that index. Participation rates, caps, and spreads determine how much of the index’s upside you actually receive. In exchange, your account value does not decrease when the index falls, though you may receive zero interest in a down year. FIAs occupy a middle ground that attracts shoppers who want more growth potential than a traditional fixed annuity but aren’t comfortable with full market exposure.
For a thorough overview, read our page on the fixed index annuity, then dig deeper into the mechanics with what index annuities — equity index and fixed index — actually are.
How Fixed and Index Annuities Work Together
Many shoppers find it helpful to see fixed and index annuities compared side by side rather than studied in isolation. Understanding how interest is credited, what surrender periods look like, and how each contract handles withdrawals can clarify which structure fits your retirement timeline in Nashville, Knoxville, Memphis, or anywhere else in Tennessee.
Our explainer on how fixed and index annuities work walks through both products together, and our dedicated comparison of the differences between fixed index annuities and fixed annuities zeroes in on the key distinctions.
Variable Annuities: A Different Animal Entirely
Unlike fixed or fixed index contracts, a variable annuity places your premium into sub-accounts that function similarly to mutual funds. Your account value rises and falls with those sub-accounts, which means you bear direct market risk. Variable annuities are regulated as securities in addition to insurance contracts, so they carry a different disclosure and suitability framework. They may suit someone with a longer time horizon who wants market participation inside an insurance wrapper, but they are not appropriate for everyone.
If you’re weighing your options, our page on the difference between a variable annuity and a fixed index annuity lays out the contrast clearly. Note: Past index or sub-account performance does not predict future results. This is not personalized financial advice.
MYGA Rates in Tennessee: Multi-Year Guaranteed Annuities
A Multi-Year Guaranteed Annuity (MYGA) locks in a contractual interest rate for a specific term — commonly two to ten years — making it one of the most straightforward annuity structures available. Tennessee shoppers often compare MYGAs to bank CDs because both offer a defined rate over a defined period, though the two products differ in important ways, including how interest is taxed and how early withdrawals are handled. Rates vary by carrier and term length, so shopping the current market matters.

Single Premium Immediate Annuity (SPIA): Income That Starts Right Away
A Single Premium Immediate Annuity converts a lump sum into a stream of income payments that typically begin within 30 days of the contract issue date. SPIAs are often used by retirees who need income now rather than at some future date — for example, someone who has just left a job in Memphis or sold a business in Knoxville and needs to replace a paycheck immediately. The trade-off is that once you hand over the premium, the terms are largely fixed.

Deferred Annuities: Building Income for the Future
A deferred annuity separates the accumulation phase — when your money grows — from the distribution phase, when you begin receiving income. This structure suits Tennessee savers who are still working or who don’t need income for several years. Fixed, fixed index, variable, and MYGA contracts can all be structured as deferred annuities, so understanding the deferred concept is foundational before you compare specific products.
Our page on what a deferred annuity is explains the accumulation and payout mechanics in plain language.
The Two Phases Every Annuity Goes Through
Every annuity contract — regardless of type — moves through an accumulation phase and an income (or annuitization) phase. How long each phase lasts, and what happens at the transition, varies significantly by product. Understanding this two-phase structure helps you ask better questions when you’re comparing contracts side by side.

Why Knowing the Differences Actually Matters
Annuity contracts are long-term commitments. Surrender periods can run five to ten years, and choosing a product that doesn’t match your income timeline or liquidity needs can be costly to unwind. Tennessee residents have access to a wide range of carriers and products, but that variety only helps if you know what you’re comparing.
Our overview of the importance of understanding different annuity types makes the case for doing your homework before you commit — and explains what’s at stake if you don’t.
