American Century SPDA review

It depends on what you prioritize. If rate competitiveness and low entry barriers are your main concerns, this is a genuinely good product — the rates are strong across all four terms, the $2,000 minimum opens the door for smaller savers, and the 0–90 issue age range is one of the widest available. If carrier financial strength is a top priority — and for many MYGA buyers it should be — the B++ rating is a real consideration that separates this product from higher-rated competitors.

The primary reason is the guaranteed rate. At 5.40% to 5.70% across the four terms, these rates are competitive with many A-rated carriers, and in some cases better. The secondary reason is accessibility — a $2,000 minimum premium is unusually low for a MYGA, which makes this product available to buyers who might not meet the $10,000 or $25,000 minimums common elsewhere. The two optional riders also add flexibility that most MYGAs do not offer, giving buyers the ability to trade free withdrawal access for a higher rate or to gain a rate-protection escape clause.

I think the American Century SPDA is best for someone who is rate-focused and comfortable doing their own due diligence on carrier strength. It fits well for a buyer who wants a competitive guaranteed rate, does not need a large carrier name, and values the low minimum and broad issue age range. It is also a reasonable fit for someone who wants to spread MYGA money across multiple carriers for diversification — putting a portion with American Century for the rate while keeping the bulk with higher-rated carriers. It is less ideal for someone who prioritizes carrier strength above all else or who is putting a large portion of their retirement savings into a single MYGA.

You are buying a guaranteed interest rate for a fixed period of time inside a tax-deferred annuity contract. There are no index strategies, no participation rates, no caps, and no crediting complexity. The rate is set at issue and does not change during the guarantee period. This is the annuity equivalent of a certificate of deposit — you deposit a single premium, the carrier guarantees a rate for 3, 5, 7, or 10 years, and your money grows at that rate with tax deferral until you withdraw it.

When you purchase the SPDA, you choose one of four guarantee periods and your interest rate is locked in for that entire term. Interest compounds on your contract value at the guaranteed rate regardless of what happens in the broader rate environment. At the end of the guarantee period, the contract does not automatically renew — instead, it defaults to a fully liquid status with a minimum 2% interest rate. That is a meaningful detail because it means you are not forced into a new surrender period, and the 2% floor on the post-guarantee rate is better than the 1% minimum many competitors offer.

The annuitization option is available after the first year, and if you annuitize over at least 5 years, surrender charges and the MVA are waived. This gives buyers an additional exit path beyond the standard free withdrawal provisions.

The two optional riders are what make this SPDA slightly different from a plain MYGA. The Free Withdrawal Waiver Rider lets you trade your 10% annual free withdrawal privilege for a modestly higher interest rate — roughly 5 basis points more across the terms. This makes sense for someone who is confident they will not need access to principal during the guarantee period and wants to maximize the rate. The Withdrawal Charges Waiver Rider (available on 5, 7, and 10-year terms only) allows the carrier to adjust your rate on each anniversary to no less than 1%, but if the rate is ever reduced below your initial rate, you can fully withdraw your balance with no surrender charges and no MVA. This is essentially a rate-protection escape clause — if the carrier cuts your rate, you can walk away clean.

You can select both riders together for the highest available rate. For example, on the 10-year term, the base rate is 5.70%, but with both riders it becomes 5.85%. Whether the extra 15 basis points is worth giving up free withdrawal access and accepting the possibility of a rate reduction is a judgment call that depends on your specific situation.

Free withdrawals of 10% of the single premium amount are available annually unless you select the Free Withdrawal Waiver Rider. Free interest withdrawals and RMD withdrawals are available immediately with no fees, which is a useful feature for retirees who need to take required minimum distributions.

The surrender charge schedules are:

3-Year: 9% / 8% / 7%

5-Year: 9% / 8% / 7% / 6% / 5%

7-Year: 9% / 8% / 7% / 6% / 5% / 4% / 3%

10-Year: 9% / 8% / 7% / 6% / 5% / 4% / 3% / 2% / 1% / 0.5%

The 9% first-year charge is on the higher side but not unusual for MYGAs. A market value adjustment also applies to withdrawals above the free amount, which can increase or decrease the value received depending on interest rate changes since issue. The death benefit pays the full account balance with no surrender charges or MVA, which is a clean provision for beneficiaries.

There are no explicit fees on the base SPDA contract. No annual charges, no administrative fees, no rider fees for the optional riders. The cost structure is embedded in the spread between what the carrier earns on your premium and what they guarantee to you — standard for MYGAs.

The tradeoffs are clear. The B++ carrier rating is the most significant one. In the MYGA space, where the product is essentially a promise to pay a guaranteed rate, the financial strength of the carrier making that promise matters more than in almost any other annuity category. The MVA adds interest rate risk to early withdrawals. And the 9% first-year surrender charge means you are committed from day one. For someone who plans to hold to maturity and is comfortable with the carrier's financial position, these tradeoffs are manageable. For someone who values carrier strength as a primary criterion, the rate advantage may not be enough to offset the rating gap.

The American Century SPDA is issued by American Century Life Insurance Company, based in Allen, Texas. Founded in 1940, American Century carries an A.M. Best rating of B++ (Good). While B++ is a stable rating, it is below the A- to A+ range that most major MYGA carriers hold. American Century is a smaller carrier in the fixed annuity space, and buyers should factor the carrier's financial strength into their decision alongside the product's rate competitiveness. For context, state guaranty association coverage typically provides a layer of protection for annuity contracts, though coverage limits vary by state and should not be treated as a substitute for carrier due diligence.
