MYGA vs FIA — How to Choose

A multi-year guaranteed annuity (MYGA) and a fixed indexed annuity (FIA) are both fixed annuity products. Both protect principal from market loss. Both grow tax-deferred. Both have surrender schedules. The differences are in how each one credits interest, how long each one locks up capital, and which retirement question each one is designed to answer.

How interest is credited

The two products use opposite philosophies for interest crediting.

A MYGA credits a guaranteed declared rate for the full term. If the contract says 5.50% for 7 years, the contract earns 5.50% in each of those 7 years. No conditions, no caps, no market dependency. The carrier sets the rate at issue based on its portfolio yield and locks it in.

A FIA credits interest based on the movement of a market index, typically the S&P 500. The upside is capped or scaled by a participation rate. The downside is floored at zero. In a strong index year, the FIA might credit 6% to 9%. In a flat or negative index year, the FIA credits 0%. The realized credit varies year to year.

When the MYGA approach wins

A MYGA is the simpler product. The consumer knows the exact dollar value at every point in the future. The carrier’s portfolio yield and the rate environment at issue determine the entire economics of the contract.

MYGA fits best when:

• The consumer wants a predictable, known return for a defined period
• Interest rates are currently elevated and the consumer wants to lock them in
• The consumer values mathematical certainty over upside potential
• The capital horizon matches a standard MYGA term length (2, 3, 5, 7, or 10 years)

When the FIA approach wins

An FIA accepts higher uncertainty in exchange for higher upside potential. In a strong market environment, an FIA can credit substantially more than a MYGA of the same term. In a flat or negative market, an FIA credits zero while the MYGA still credits its locked rate.

FIA fits best when:

• The consumer wants principal protection AND some indexed upside
• The capital horizon is longer than a typical MYGA (often 7 to 14 years)
• The consumer plans to use an optional income rider for guaranteed lifetime income
• The consumer is willing to accept volatility in credited interest in exchange for higher long-run potential

A worked comparison

A $100,000 premium placed in a 7-year MYGA at 5.50% grows to approximately $145,500 at the end of the term, regardless of market movement.

A $100,000 premium placed in a 7-year FIA with a 7% cap, 100% participation, 0% floor, and the S&P 500 as the reference index produces a different outcome. Over a 7-year window that includes typical market volatility (some years up significantly, one or two down years), the FIA might credit between 3% and 7% per year on average. The cumulative value at term end could range from approximately $122,000 (flat market) to $162,000 (strong market).

The MYGA is bounded above and below by its declared rate. The FIA is bounded above by the cap and below by the floor.

Surrender schedules

MYGAs typically have surrender periods that match the term length. A 5-year MYGA has a 5-year surrender schedule that reaches 0% at term end. The contract owner can then take the full value, renew, annuitize, or 1035 exchange to another carrier.

FIAs typically have longer surrender periods than their natural term, often 10 to 14 years. The longer schedule is partly because FIAs carry higher acquisition costs (richer features, larger commissions) that the carrier needs to recover over a longer window.

For a consumer who needs liquidity flexibility, MYGA terms align with the surrender schedule more cleanly than FIA terms.

Tax treatment

MYGA and FIA share identical tax treatment. Both grow tax-deferred. Both tax withdrawals as ordinary income, not as long-term capital gains. Both apply the 10% pre-59½ federal tax penalty unless an exception applies. Both can be funded with qualified or non-qualified money.

How to decide

A clean rule of thumb:

• If the capital is intended for a known need in 3 to 7 years and the consumer wants a guaranteed dollar amount, a MYGA fits.
• If the capital is intended for retirement income 10+ years out and the consumer wants principal protection with the option of indexed growth, an FIA fits.
• If the consumer wants guaranteed lifetime income, the FIA with an income rider or a separate SPIA / DIA is the better category match.

The decision is rarely between MYGA and FIA in isolation. Most retirement plans use multiple products: a short MYGA for years 1-5 of spending, plus a longer FIA or income annuity for years 6+.
