- A CD is a bank deposit backed by FDIC insurance. A fixed annuity is an insurance contract backed by the issuing company's claims-paying ability and, as a backstop, your state guaranty association.
- CD interest is taxable every year whether you withdraw it or not. Deferred annuity interest is not taxed until you take it out.
- CD early withdrawal penalties are typically a few months of interest. Annuity surrender charges start much higher and decline over a schedule that can run a decade.
- Only the annuity can convert to guaranteed lifetime income. A CD cannot, at any price.
- Annuity rates are frequently higher, and the higher rate is compensation for accepting a different set of risks and restrictions.
On a rate sheet a three-year CD and a three-year fixed annuity look like the same product with different numbers. They are not. The comparison that matters is what backs the guarantee, how the interest is taxed, and what happens if you need the money early.
The relevant annuity for this comparison is a MYGA — a multi-year guaranteed annuity, which credits a guaranteed fixed rate for a set term. Indexed and variable annuities are different products and do not belong in a CD comparison at all.
Whether you searched this as annuity vs CD or CD vs annuity, it is the same comparison: a bank product insured by the FDIC against an insurance product backed by a carrier's claims-paying ability.
What actually backs each guarantee
This is the most important difference and the one most often reduced to a single word.
A CD is a bank deposit, insured by the FDIC up to $250,000 per depositor, per institution, per ownership category. That is a federal government guarantee. If the bank fails, the FDIC makes depositors whole up to the limit, and it does so quickly.
A fixed annuity is an insurance contract. The guarantee rests on the issuing insurance company's financial strength and claims-paying ability. Insurers are regulated at the state level and hold reserves against their obligations, and insurer failures are rare. But the backstop is a state guaranty association rather than a federal agency, and coverage limits vary by state.
The practical consequence: with a CD you check the FDIC limit. With an annuity you check the carrier's rating and your state's guaranty limit. Neither is difficult. Skipping the second one is where people get into trouble, particularly with the lower-rated carriers that tend to post the highest rates.
Tax treatment, which is where the annuity wins
CD interest is taxable in the year credited. Leave it to compound and the bank still issues a 1099-INT and you still owe tax on interest you never touched. Over a long holding period in a high bracket, paying tax annually on money that stays in the account is a meaningful drag.
Interest inside a non-qualified deferred annuity is not taxed until you withdraw it. It compounds gross rather than net.
Two caveats keep this honest. Deferral is not forgiveness — the tax arrives when you withdraw, at ordinary income rates, and annuity gains never receive capital gains treatment or a step-up in basis at death. And withdrawals from a non-qualified annuity come out interest-first, so the first dollars out are fully taxable. Before 59½ an additional 10% federal tax generally applies to the taxable portion.
Tax deferral is genuinely valuable if you are in a high bracket now and expect a lower one later. It is worth much less if your bracket will not change, and it can work against you if the alternative is a long-held taxable position passing to heirs with a step-up.
Liquidity, which is where the CD wins
Break a CD early and you typically forfeit a set number of months of interest. Painful, bounded, predictable, and it does not usually reach your principal.
Break an annuity early and you face a surrender charge that starts high and declines over a schedule that can run a decade, potentially a market value adjustment on top, and potentially the 10% federal penalty if you are under 59½. Three separate costs from three different sources.
Most deferred annuities include a free withdrawal allowance, often around 10% of contract value annually, which softens this considerably. But the structural point stands: an annuity commits your money for longer and charges more to break that commitment. That is precisely why it can pay more.
Rates, and why the annuity usually leads
MYGA rates frequently exceed CD rates at the same term. The reason is structural rather than promotional.
Banks hold shorter-duration, more liquid assets because depositors can leave. Insurers, protected by the surrender schedule, invest in longer-duration assets that yield more, and pass part of that yield through to you.
Two things to check before treating a rate advantage as free money. First, the carrier's financial strength rating — the widest rate gaps usually come from carriers rated below the top tiers, and the extra yield is compensation for that. Second, the guaranteed minimum rate after the initial term, since some contracts renew at a much lower rate and the attractive number applied only to the guarantee period.
The thing only an annuity can do
A CD matures, returns your principal and interest, and the relationship ends. That is the whole product.
An annuity can convert a balance into guaranteed lifetime income — payments that continue as long as you live, however long that turns out to be. This is not a better interest rate. It is a transfer of longevity risk to the insurance company, and it is the only thing in retail finance that does it.
If your concern is outliving your money, no CD ladder solves it, because a ladder eventually runs out and a lifetime payment does not. If your concern is preserving a known sum for a known date, the lifetime feature is something you may be paying for and will never use.
Choosing between them
A CD generally fits money you may need within a few years, balances at or under the FDIC limit where simplicity matters, situations where you want no possibility of principal loss and no dependence on a company's health, and anyone in a low enough bracket that deferral is worth little.
A MYGA generally fits money you are confident you will not touch for the full term, a high current tax bracket with a lower expected bracket later, cases where the rate advantage is meaningful and the carrier is strongly rated, and situations where converting to lifetime income later is a live possibility.
Both can fit at once. There is no rule requiring you to choose. A common structure keeps near-term reserves in CDs or a savings account and places longer-horizon money in a MYGA, laddering both. That combination gets the liquidity where it is needed and the yield and deferral where they help.
What should not decide it is a rate comparison alone. A carrier's rating, your state's guaranty limit, your bracket now versus later, and the date you might actually need the money all change the answer more than fifty basis points does.
Matching the term to the money
Both products ask the same first question: when do you actually need this money back? Answer that honestly and the choice narrows quickly.
CDs typically run from three months to five years. Fixed annuities run from three to ten, occasionally longer. A three-year CD and a three-year MYGA are the closest comparison available, and even there the surrender period on the annuity may extend past the rate guarantee — check whether the two match, because on some contracts they do not.
Because interest rates move, neither product should absorb everything at once. Laddering across several maturity dates means a portion comes due each year, which lets you reprice into current market conditions instead of committing the whole balance to one moment's rate. This works with CDs, with fixed annuities, or with both in the same ladder.
The rate after the guarantee ends
A CD matures and pays out. A fixed annuity usually does not — it rolls into a renewal rate, and that renewal is frequently far below the headline rate that attracted you. The contract will specify a guaranteed minimum rate, which is the floor the carrier can drop to, and that floor is often startlingly low.
Ask for the guaranteed rate and the guaranteed minimum as two separate numbers. A five-year contract at 5.4% that renews at 1% is a five-year product, and it should be evaluated as one. Know your options at the end of the term before the term begins.
Where risk tolerance actually enters
Neither of these is a market investment, so risk tolerance here does not mean tolerance for volatility. It means tolerance for two specific things: an insurer's credit rather than a federal guarantee, and a long lockup with expensive exits.
If either genuinely keeps you up at night, the extra fixed interest a MYGA pays is not worth it to you, and a CD is the better fit regardless of what the rate comparison says. Financial goals that depend on certainty of access should be funded with the product that provides certainty of access.
