Value after tax
The annuity grows on the full rate; the CD grows on what is left after tax each year. That is the mechanism. The gap column compares the annuity after the tax that would be due on cash-out against the CD, so both sides are measured the same way. Comparing a pre-tax annuity balance to an after-tax CD balance overstates the advantage.
| Year | Annuity value | Annuity if cashed | CD value | CD tax that year | Gap, like for like |

Three different engines. The quoted rate alone does not tell you which one you are buying.
A CD's APY already includes compounding, so the quoted number is honest about growth. The drag is tax: interest is reported every year whether or not it is touched, so only the after-tax remainder keeps compounding.
Growth compounds on the full rate with nothing pulled out for tax along the way. This is the version that genuinely beats a CD at the same headline rate, because the money that would have gone to tax stays invested and keeps earning.
Interest is credited on the original deposit only and never earns on itself. A high simple headline can lose to a lower compounding rate over the same term, which is why the quoted number has to be converted before any comparison means anything.
| Measure | Annuity | CD |
|---|---|---|
| Quoted rate | — | — |
| Compounds on itself | — | Yes, that is what APY means |
| Taxed each year | No, deferred | Yes |
| Effective yield, before tax | — | — |
| Effective yield, after tax | — | — |
The last row is the only apples-to-apples number on this page: what each one actually returned per year after tax, over the term entered above.
These differences decide suitability more often than the rate does.
A CD has one penalty, usually some months of interest. An annuity has a surrender-charge schedule that declines over the term, and most contracts allow a free withdrawal each year, commonly around 10% or the interest earned.
Ask what the client would do if they needed the money in year two.
A CD is insured by the FDIC to the standard limit, per depositor, per bank, per ownership category. An annuity is backed by the issuing carrier's claims-paying ability. The carrier's financial strength rating is the thing to look at.
Different kind of promise, not simply a stronger or weaker one.
Many annuities apply an MVA on early surrender. If rates rose since purchase it reduces the payout; if rates fell it can increase it. It applies on top of the surrender charge, and it cuts in both directions.
Confirm whether the specific contract carries one.
Gains withdrawn from an annuity before 59½ generally carry a 10% federal penalty on the gain, separate from and in addition to any surrender charge. A CD has no such age rule.
This tool applies the penalty automatically when the math calls for it.
Deferral is the annuity's advantage and it is real, but the gain is eventually taxed as ordinary income rather than at capital-gains rates, and withdrawals come out gains-first.
A client who hears "tax-free" has misunderstood, and that needs correcting.
A CD matures and the bank hands the money back. An annuity reaching the end of its guarantee period typically offers renewal at a new rate, an exchange, annuitization, or surrender, each with different consequences.
The renewal rate is rarely the headline rate. Ask.
California requirements — advisor
Guaranty association coverage is not a sales argument. California law restricts using the existence of the California Life & Health Insurance Guaranty Association to induce a purchase. Do not reference it in a comparison, in writing or verbally, as a reason to buy.
Senior suitability. California imposes heightened suitability and disclosure duties for annuity sales to older buyers, and buyers aged 60 and above generally receive a 30-day free-look period rather than the standard window.
Do not present an annuity as a deposit. An annuity is not a bank product, is not FDIC insured, and must not be described in language that implies otherwise. Side-by-side comparisons with CDs invite exactly that confusion, so the distinction has to be stated plainly, not buried.
Verify current code sections and free-look duration against the California Insurance Code before relying on this summary in a compliance context. It is a working reminder for the person using the tool, not a legal opinion.
