MYGA vs CD: see the tax-deferred math.
A Multi-Year Guaranteed Annuity and a CD look similar — both guarantee a fixed rate. The structure underneath is very different. This calculator shows you exactly what that difference is worth in dollars, for your situation.
Your inputs
Federal rate. 22% is most common for retirees.
Worst-case lump sum. Spreading withdrawals across years, or 1035-exchanging into another MYGA, usually keeps the effective rate well below this.
CD interest is taxed every year as it’s earned, so less compounds. MYGA gain compounds untaxed and is only taxed when you withdraw.
Here's the plain math. $250,000 at 5.5% for 5 years in a MYGA compounds tax-deferred to $326,740 — you don't pay tax on the growth until you actually withdraw. If you withdrew the whole balance at year 5, you'd owe roughly $16,883 in income tax on the gain at your 22% bracket, leaving you with about $309,857 in your pocket.
The same $250,000 in a CD at 4.5%, taxed annually as you go, would land you around $297,065 after taxes. So the apples-to-apples after-tax gap is about $12,792 — real money you keep, just from the structure.
One nuance: most retirees don't withdraw an entire MYGA in a single year. Spreading it over multiple years (or rolling it into another MYGA via a 1035 exchange) usually keeps the effective tax rate lower than the bracket shown here. The number above is the worst case.
MYGA is one piece of a retirement plan — not the whole plan. It doesn't solve tax bracket strategy at withdrawal, Social Security timing, IRMAA brackets (the Medicare premium surcharges that kick in above certain income thresholds), or sequence-of-returns risk. Use MYGA for the part of your portfolio that needs to be safe and predictable.

MYGAs are long-term products; early withdrawals may be subject to surrender charges and the 10% IRS penalty if taken before age 59½.

Frequently asked questions
What is a MYGA?
A MYGA (Multi-Year Guaranteed Annuity) is a fixed annuity that pays a guaranteed interest rate for a set period — typically 3 to 10 years. Think of it like a CD issued by an insurance company, with tax-deferred growth.
How is a MYGA different from a CD?
Both offer guaranteed rates. The structural differences: MYGA interest compounds tax-deferred until withdrawal (CDs are taxed annually), MYGA rates are often higher than equivalent-term CDs, MYGAs are backed by insurance carrier reserves + state guaranty associations rather than FDIC. CDs offer more liquidity.
Why does tax deferral matter so much?
With a CD, you owe income tax on interest every year, which reduces what compounds. With a MYGA on after-tax money, all interest compounds without annual tax drag until you withdraw. Over 5-10 years, especially in higher tax brackets, this can mean thousands more.
Are MYGAs safe?
MYGAs are backed by the claims-paying ability of the issuing insurance company. State guaranty associations provide an additional safety net — the NAIC model floor is $250,000 per owner per carrier in present value of annuity benefits; some states (NY, CT, WA) cover up to $500,000. Carrier financial strength matters: AM Best rating is one input alongside reinsurance, capitalization, and parent company strength.
What if I need the money before the term ends?
Most MYGAs allow penalty-free withdrawals of up to 10% per year. Beyond that, surrender charges apply (typically 7-10% in year one, declining annually). Withdrawals before age 59½ also trigger a 10% IRS penalty in addition to ordinary income tax. MYGAs are best used for money you genuinely won't need during the surrender period.
