Fixed indexed annuity vs. CD: what's the difference?

Both protect principal — through very different mechanisms.

Short Answer

Both a CD and an FIA can protect principal, but through different guarantees. A CD is a bank deposit product with a fixed term and rate, backed by FDIC insurance (within limits). An FIA is an insurance contract whose interest is index-linked and whose guarantees depend on the issuing insurer — not FDIC insured. A CD offers certainty; an FIA offers potential plus protection with different liquidity and tax treatment.

Guarantee source: CD — FDIC (within limits); FIA — issuing insurance company.
Interest: CD — fixed, declared rate; FIA — index-linked, variable based on crediting method and limits.
Term/liquidity: CD — fixed term with early-withdrawal penalties; FIA — surrender period with free withdrawal provisions.
Tax: CD interest is taxed annually; FIA growth is tax-deferred until withdrawn.

Who Might Consider This

A CD suits money where certainty and short-to-medium terms matter. An FIA may suit a longer-horizon portion where some index-linked potential and tax-deferred growth are desired alongside protection.

Common Misunderstandings

"A CD and an FIA are equally safe." They protect principal through different backstops (FDIC vs. insurer). "Safe" depends on which risk you mean.
