Fixed Annuity vs CD: Which Guaranteed Rate Fits Your Money?

A certificate of deposit is a time deposit at a bank or credit union. You agree to leave a sum for a term, usually three months to five years, and the institution pays a fixed rate. Deposits are insured by the FDIC (or the NCUA at a credit union) up to $250,000 per depositor, per institution, per ownership category, so a CD carries essentially no credit risk within that limit.

A multi year guaranteed annuity, often shortened to MYGA, is the insurance industry's version of the same idea. You pay a single premium to a life insurance company, which credits a fixed rate for a term of two to ten years. The guarantee is the insurer's promise, backed by the reserves state regulators require and, if the insurer fails, by your state's life and health guaranty association up to its limit. A MYGA is the fixed annuity people mean when they compare annuities to CDs; fixed index annuities are a different product with index-linked interest.

Takeaway: Compare a CD to a MYGA, not to annuities in general. Index and variable annuities solve different problems.

The table below covers the differences that decide most cases. Rates are left out on purpose: both products reprice constantly, and the gap between them changes with the interest rate environment. Current illustrative figures are on the rates pages linked at the end of this guide.

CD interest is income in the year it is credited, whether or not you touch it. If you are still working and in a high bracket, that annual tax bite reduces the amount that compounds. MYGA interest compounds untaxed inside the contract, and you pay ordinary income tax only on what you withdraw, earnings first. If you hold the contract until retirement and withdraw in a lower bracket, the deferral is worth real money; if you withdraw every year in the same bracket, the advantage shrinks to the compounding on the deferred tax.

Deferral has a price: the 10% additional federal tax on earnings withdrawn before age 59 and a half, which does not apply to a CD. For a buyer under 59 and a half who may need the money before then, that rule alone can tip the comparison toward the CD. For a buyer past that age, the annuity's deferral is a clean advantage on non-retirement money.

Inside an IRA the comparison changes. Both a CD and an annuity held in an IRA are already tax-deferred, so the annuity's deferral adds nothing; the decision comes down to rate, term, liquidity and the option to annuitize.

Takeaway: To compare after tax, ask what each dollar of interest is worth after your marginal rate this year for the CD, and after your expected rate in the withdrawal year for the annuity.

FDIC insurance is a federal government guarantee, paid promptly, and it is the reason a CD is the benchmark for safe money. A MYGA's safety rests first on the insurer's financial strength, which is why rating agency grades (AM Best, S&P, Moody's, Fitch) matter, and second on the state guaranty association, an industry-funded safety net that pays covered benefits only after a failed insurer is liquidated. Coverage for annuity benefits is commonly $250,000 per owner per insurer, and some states set different limits.

The practical rules are to buy from a highly rated insurer, to keep any one contract within your state's guaranty limit, and to spread larger sums across insurers just as you would spread deposits across banks to stay under FDIC limits. Neither product is riskless in every scenario; a well-chosen MYGA within the limit is a conservative holding, but it is not the same guarantee as a federal deposit insurance fund.

Break a CD early and the bank charges a penalty stated in months of interest, commonly three to twelve depending on the term. If you leave in the first months, the penalty can exceed the interest earned and eat into principal, but the cost is simple and capped.

Leave a MYGA early and three things can happen. The surrender charge, a percentage that starts high and declines each year of the term, applies to any withdrawal above the free amount. A market value adjustment, if the contract has one, raises or lowers the surrender value depending on whether interest rates have risen or fallen since you bought. And the earnings you withdraw are taxable, with the 10% penalty before 59 and a half. Most contracts waive surrender charges for death, terminal illness, nursing home confinement and required minimum distributions, which is worth confirming before you sign.

• Match the term to money you are confident you will not need; the free withdrawal allowance is for interest and small needs, not for the whole balance.
• Read the surrender schedule and any MVA clause; they are the true cost of the higher guaranteed rate.
• Check the waivers for death, illness, nursing care and RMDs.

A maturing CD renews automatically at whatever rate the bank is paying unless you act within a short grace period, or you withdraw the money. A maturing MYGA gives you a window, commonly 30 days, with more choices: withdraw the whole value, renew for a new guaranteed term, move the money tax-free to another insurer's annuity under a Section 1035 exchange, or annuitize the balance into guaranteed payments for a period or for life. The 1035 exchange is the feature that lets you shop for the best renewal rate without triggering the deferred tax.

Laddering works with both. Splitting a sum across two, three and five-year terms keeps money maturing regularly, which smooths out rate changes and gives you liquidity at intervals. Some savers ladder CDs for the near years and MYGAs for the longer ones, keeping the FDIC-insured money closest to hand and the tax-deferred money further out.

A CD fits money you may need within a few years, savers under 59 and a half who cannot rule out an early withdrawal, and anyone who wants the federal deposit guarantee above all. It also fits an emergency reserve, where simplicity matters more than yield.

A MYGA fits after-tax savings you will not touch for the term, especially for someone past 59 and a half in a high bracket now who expects a lower bracket in retirement, and for anyone who may eventually want the balance converted into lifetime income. It also fits the portion of a retirement plan you want locked at a guaranteed rate, provided the surrender term suits your plans.

Most bad outcomes in this comparison come from a mismatch between the term and the buyer's real horizon, not from choosing the wrong product.

• Comparing a five-year MYGA rate to a one-year CD rate: compare like terms.
• Buying a MYGA under 59 and a half with money that might be needed before then, then paying the surrender charge and the 10% penalty to get it.
• Putting more than your state guaranty limit into one insurer, or more than $250,000 in one bank ownership category.
• Missing the renewal window on a MYGA and being rolled into a new term at a lower rate.
• Ignoring the tax on CD interest when comparing headline rates.
