On published rate alone, MassMutual posts the higher figure on more of the terms shown here. For safety-first buyers, the carrier with the higher A.M. Best rating wins (MassMutual is rated higher). Both clear our A- preferred-tier threshold on the letter grade alone. An A.M. Best rating is an opinion of an insurer's ability to meet its obligations, not a guarantee, and it can be changed or withdrawn at any time; annuity guarantees are not FDIC-insured. Track Retirement is not a licensed insurance agent and does not recommend either contract; this comparison is general information, not advice.
The headline MYGA rate is only meaningful if the carrier honors a multi-decade contract. Nationwide and MassMutual differ on both axes — use the table for the numbers and the framing below for the decision.
Illustrative, 24% tax bracket, both lines after tax: $6,635 more over 5 years, almost all of it from the rate difference (5.75% vs 4.4%) rather than from deferral. The 4.4% CD leg is an assumed APY, not a quote; the FDIC all-institution average is 1.41%. A MYGA is an insurance contract, not FDIC-insured.
Whichever carrier you lean toward, most of the gap above is the rate difference rather than the tax treatment — the deferral itself is the smaller part. Either way it only pays off if the money can stay put for the full term with a strong insurer.

MassMutual posts the higher figure on 3 of 5 MYGA term lengths in these illustrative, representative rates. Its 5-year figure is 5.70% vs. 3.50%. These are illustrative figures, not a live quote — your actual rate depends on premium, state, and carrier filing, and a higher posted rate often comes from a lower-rated carrier.
Nationwide is rated A+ by A.M. Best; MassMutual is rated A++. Both currently sit at or above our A- financial-strength floor on the letter grade alone. An A.M. Best rating is an opinion of an insurer's ability to meet its obligations; it is not a guarantee, and it can be changed or withdrawn at any time. Annuity guarantees are not FDIC-insured.
For MYGAs, neither carrier charges explicit fees. The quoted rate is what you earn, provided you hold to term. For variable annuities, fees vary significantly by product; check the specific contract.
Nationwide operates in approximately 50 states; MassMutual in approximately 50. State counts are approximate and change as filings are approved or withdrawn — some carriers are not admitted in every state, and California, New York and Oregon in particular have their own filing requirements. Confirm with the carrier or a state-licensed agent that a specific contract is available where you live before you apply.
