What Is a Multi-Year Guaranteed Annuity (MYGA)?

Updated July 9, 2026 5 min read

Among the many annuity variations, a multi-year guaranteed annuity is one of the simpler ones to describe, because its core promise resembles a product most people already understand.

The short answer

A multi-year guaranteed annuity, or MYGA, is a fixed annuity that locks in a set interest rate for a specific number of years, typically somewhere between three and ten, chosen at purchase. During that period, the rate doesn’t change regardless of what happens in broader interest rate conditions. At the end of the term, the owner generally chooses to renew into a new rate period, move the money elsewhere, or begin taking income, similar in structure to how a certificate of deposit works at maturity.

How the rate period works

The insurer commits to crediting a fixed rate for the entire term, which removes the year-to-year uncertainty that comes with a variable-rate product. This simplicity is the main appeal: the growth calculation doesn’t depend on market performance, an index, or any variable formula — just a fixed rate applied for a fixed number of years, agreed to upfront.

How it compares to a CD

The comparison to a certificate of deposit is a useful mental model, but the products aren’t identical. Both lock in a rate for a set term. Both typically carry a penalty for accessing the money before the term ends, though the size and structure of that penalty differ. The meaningful difference involves who’s backing the promise — a CD is generally covered by federal deposit insurance, while a MYGA’s backing rests on the issuing insurance company’s own claims-paying ability, sometimes backstopped by state guaranty associations up to certain limits. MYGAs also grow tax-deferred, the same general concept that applies to non-qualified annuities, while CD interest is typically taxed in the year it’s earned.

What happens at the end of the term

When the rate period ends, the contract usually offers a window to decide what’s next: renew into a new multi-year rate, which may differ from the original, transfer the value to another annuity through a tax-free exchange under current rules, take a lump sum, or convert the balance into an income stream. Missing that window can sometimes trigger a default renewal at whatever rate the insurer is then offering, so the timing of that decision matters.

What tends to factor into the comparison

The takeaway

A MYGA offers a straightforward, fixed-rate structure for a defined period, conceptually close to a CD but built on a different kind of backing and different tax treatment. Because rate periods, surrender terms, and available rates vary by insurer and change constantly, comparing the actual terms of a specific contract is more useful than relying on the general concept alone.
