Short answer
Both protect principal; a MYGA defers tax and often pays more, a CD is FDIC-insured.
A MYGA (a fixed annuity) and a CD both pay a set rate for a set term with principal protected. The differences: a MYGA grows tax-deferred until you withdraw, while CD interest is generally taxed each year; a MYGA often offers a higher rate for multi-year terms; and a CD is FDIC-insured, while a MYGA is backed by the insurer and state guaranty associations. Choose a CD for federal deposit insurance and simplicity, and a MYGA when the higher rate and tax deferral matter more.
