FIA vs. MYGA: Which One Is Right for You?

Same Family, Different Approach

FIAs (Fixed Indexed Annuities) and MYGAs (Multi-Year Guaranteed Annuities) share the same core benefits: principal protection, tax deferral, and no ongoing management fees.

Where they differ is in how interest is calculated — and that difference shapes who each product is best for.

Side-by-Side

The Core Tradeoff

MYGA: You know exactly what rate you'll earn every year. A 5-year MYGA at 5.20% earns 5.20% annually, guaranteed, for five years. No surprises.

FIA: Your interest credit is linked to an index (e.g., S&P 500). In a strong year, you might earn 9% (up to your cap). In a flat or down year, you earn 0%. Over a full market cycle, FIA credited returns have historically landed somewhere between a MYGA and direct equity exposure — though past index performance doesn't guarantee future FIA credits.

Neither is objectively better. The question is what you're optimizing for.

Who Does Better With a MYGA

You want certainty. If knowing your exact account value at the end of the term matters — for a specific goal, tax planning, or peace of mind — a MYGA delivers that. FIAs can't.

Shorter time horizon. MYGAs are available in 3- and 4-year terms. FIAs typically require a 7–10 year commitment to make sense.

Current MYGA rates are strong. When MYGA rates are competitive (as they've been in recent years), the guaranteed return may exceed what a more complex FIA is likely to produce in a moderate-growth environment.

You want simplicity. MYGAs are easy to understand, easy to compare, and straightforward to track. FIAs involve cap rates, participation rates, index methodologies, and crediting periods.

Who Does Better With a FIA

Longer time horizon. Over 10 or more years, the probability of FIA credits meaningfully exceeding MYGA rates increases. More market cycles means more opportunity to capture capped gains.

Interested in income rider features. Income riders are typically attached to FIAs (not MYGAs). If a guaranteed future income stream is part of the plan, an FIA with a rider may be the vehicle.

Wants asymmetric participation. You'd like the chance to do better than a fixed rate in strong markets, while maintaining the floor in down markets. The FIA structure provides that asymmetry — in exchange for accepting the cap and the uncertainty.

Time to let the crediting strategy average out. FIA performance varies year to year. The case for FIAs strengthens with longer hold periods where multiple crediting cycles occur.

The One Myth to Dispel

"FIAs participate in the stock market." Not exactly. Your premium isn't in the market. The carrier uses a portion of its investment income to purchase index options — which fund the crediting formula. A 0% credit year doesn't mean you lost money. It means you didn't earn any interest that year.

The principal protection is real in both products. The distinction is whether your growth is fixed (MYGA) or index-linked with a floor (FIA).

Making the Call

Start with your timeline.

• 3–7 years: MYGA is the natural fit
• 7+ years with income planning: FIA is worth serious consideration
• 7+ years, pure accumulation, rate certainty preferred: a longer MYGA or ladder of MYGAs may still win

Then look at rates. Compare current MYGA rates against the cap rates available on FIAs you're considering. Model a few scenarios. The math often clarifies the decision faster than the product descriptions do.
