SPIA vs DIA vs MYGA: Choosing the Right Income Annuity

What are SPIAs, DIAs and MYGAs?

Three products do most of the heavy lifting whenever someone builds guaranteed income into a retirement plan. All three are fixed annuities backed by an insurance company's claims-paying ability, yet each one is engineered for a different moment in retirement.

A single premium immediate annuity (SPIA) takes one deposit and turns it directly into income, with the first check typically landing inside 12 months. Hand an insurer $100,000, for example, and it agrees to send you money for as long as you live, or for a fixed number of years if that is how you structure it. Your original deposit is not sitting there waiting for you anymore, but what you get in return is a payment the insurer is contractually on the hook to keep sending.

A deferred income annuity (DIA) is built the same way except for one detail: you set a future date, often 5, 10 or 20 years out, before the first check arrives. Pushing that start date back gives the insurer years to grow your money before it owes you a single payment, which is exactly why a deferred payout ends up so much bigger per dollar than an immediate one. Picking between a SPIA and a DIA really comes down to a single question: how soon do you actually need the paycheck?

A multi-year guaranteed annuity (MYGA) is a different kind of tool altogether. It is a tax-deferred contract that pays a set rate of interest across a fixed term, commonly somewhere between 3 and 10 years, and it sends you no monthly income at all unless you specifically ask for one. Once the term wraps up, you can pull out your deposit plus interest, roll into a new term, move the balance into a different annuity through a 1035 exchange, or convert it into an income stream. Of the three, the MYGA is the flexible, growth-first option.

Whichever of the three you are weighing, the guarantee behind it is only as strong as the company issuing the contract. All three product types depend on the insurer's claims-paying ability, so it is worth understanding how carriers get rated before you commit real money to any of them, especially with a SPIA or DIA, where the decision to annuitize typically cannot be undone once it is made.

How do payouts compare on $100,000?

SPIA and DIA checks are priced from current interest rates, mortality assumptions and your age on the day you buy, and MYGA rates track the broader rate environment, so any table of numbers here would be out of date within days. Rather than publish figures that go stale that fast, request a live, personalized quote built around your own age, state and the contracts actually on the market right now.

Even so, a purely hypothetical set of numbers helps show the shape of the comparison. Picture $100,000 placed in each contract type for a hypothetical 65-year-old buyer: a SPIA might pay somewhere near $7,000 a year beginning immediately; a DIA deferred 10 years might pay closer to $12,000 a year once it turns on at 75; a DIA deferred 20 years might pay something like $25,000 a year once it starts at 85; and a MYGA crediting a hypothetical 5% would simply add $5,000 of interest during its first year. None of these figures are quotes, just rough illustrations of scale.

Comparing real numbers costs nothing and does not obligate you to buy anything. A licensed strategist can pull current SPIA, DIA and MYGA pricing side by side for your exact age and state, so the choice between the three is based on your own numbers instead of a stale table sitting on a webpage.

That pattern shows up no matter where actual pricing sits in a given year. Pushing the start date back hands the insurance company more years to grow your premium before it has to pay anything out, and it stacks mortality credits on top of that growth, meaning some of the eventual value comes from premium left behind by people who never live long enough to collect.

When SPIAs win

A SPIA tends to be the right call when income needs to start now and the priority is squeezing the largest guaranteed check out of the dollars committed today. That usually describes retirees who:

• Are already past 70 and want to maximize today's income, since age is one of the biggest drivers of the payout rate
• Have a real, ongoing gap between Social Security and essential monthly bills that needs to close immediately
• Want to hand off longevity risk on part of their savings without having to manage investments for that portion

The standard complaint about a SPIA is that your principal disappears. That is accurate for its plainest form, a life-only payout, where checks simply stop the day you die. Layering in a cash-refund or period-certain feature keeps money moving to your family if you pass away early, trading a somewhat smaller monthly check for that protection, and it is the path most buyers choose today over a plain life-only contract.

Worth remembering: once you fund a SPIA and choose a payout option, that choice is generally locked in for good. There is no surrender period to sit out and no changing your mind a few years later the way there can be with a MYGA. That permanence is exactly why the decision deserves a full comparison across carriers and payout structures before any money moves, not just a look at the monthly number.

When DIAs win

A DIA functions as longevity insurance. You buy it well before you plan to use it, specifically to guard against the risk most retirees underrate: living a genuinely long time. Weighing a DIA against a MYGA usually comes down to whether you would rather lock in guaranteed lifetime income starting in your 80s, or keep the flexibility of getting your principal back at the end of a much shorter MYGA term.

Two forces combine to make the math work: years of growth on your premium before the first payment is due, and mortality credits, the portion of premium left behind by people who never live to collect, shared among everyone still in the pool. Purely as a hypothetical example, a $60,000 DIA purchased at 65 to start paying at 85 might produce something in the neighborhood of $18,000 to $24,000 a year for life once income begins. Stay alive to collect for even ten years, to 95, and that adds up to $180,000 to $240,000 paid out against a $60,000 deposit, guaranteed the moment the contract is issued.

The obvious catch is that none of it pays out if you do not live to see it. A return-of-premium option or an income rider with a built-in death benefit protects your heirs if you pass away before or shortly after income starts, though it trims the size of the checks. Most buyers approach a DIA the way they approach homeowners insurance: hoping never to need it, while being glad to have it if they end up living a long life.

One more tradeoff worth flagging: a standard DIA pays a fixed dollar amount once it starts, and a long deferral period gives inflation plenty of time to chip away at what that fixed check can actually buy. Some contracts offer a cost-of-living adjustment rider to address this, usually in exchange for a smaller starting payment, and it is worth pricing both versions side by side before deciding which tradeoff fits your plan.

When MYGAs win

A MYGA plays a different role entirely. It locks in a guaranteed interest rate, pushes the tax bill on that interest into the future, and leaves your original deposit untouched so you get to decide what happens to it once the term is up.

Reach for a MYGA when the money in question has a known use date somewhere between 3 and 10 years out, when putting off tax on the interest beats paying it every year, or when you are simply not ready to make a lifetime income decision yet. MYGAs also carry the early rungs of a well-built income ladder especially well, funding the years before a SPIA or DIA is due to take over the paycheck. That handoff role is exactly what people mean when they call a MYGA an income bridge.

The flexibility comes with one boundary worth knowing up front: pulling out more than the contract's free withdrawal amount before the term ends usually triggers a surrender charge that shrinks the longer you have left on the term. That is a very different kind of tradeoff than a SPIA or DIA, where the money is committed on day one in exchange for a lifetime guarantee, so the MYGA is best reserved for money you are fairly confident you will not need to touch early.

Combining all three in a ladder

No single one of these products can cover every job, which is exactly why a lot of income ladders lean on all three at once. Purely as a hypothetical illustration, picture a 65-year-old retiree setting aside $500,000 for guaranteed income:

• $280,000 spread across 3-, 5- and 7-year MYGAs, funding spending from 65 through roughly 74
• $170,000 into a SPIA, paying something like $13,500 a year beginning around 74
• $50,000 into a DIA, paying something like $19,000 a year once it starts around 84

That kind of structure covers a paycheck floor today, locks in a second wave of income while rates and health still favor the buyer, and guards against running short of money deep into the 90s. Once a shape like this exists on paper, an income gap analysis is the natural next step, since it pins down exactly how large a gap the ladder needs to close before any money moves.

Taxes work differently across the three rungs, too, which is worth factoring into how a ladder gets built. A SPIA or DIA bought with after-tax money uses an exclusion ratio to treat part of each check as a tax-free return of your own principal, while the rest counts as taxable interest. A MYGA, by contrast, defers all of its interest from tax until you actually withdraw it, so the timing of those withdrawals is something you control rather than something baked into a payout formula. None of this replaces a conversation with a tax professional about your own return, but it explains why the same $500,000 can produce a noticeably different tax picture depending on how it is split across the three products.

Which annuity should I pick for each rung of my income ladder?

Each product answers to a different point on the retirement timeline, and most well-built plans end up using more than one:

• SPIA: income begins within roughly 12 months. Best for the front rung, when a guaranteed paycheck needs to start immediately and the priority is the highest payout per dollar committed, without market exposure.
• DIA: pay now, income begins 5, 10 or 20 years later. Best for the back rung, functioning as insurance against outliving your savings. The longer the deferral, the more income each dollar eventually produces.
• MYGA: a fixed rate locked in for 3, 5, 7 or 10 years, after which you withdraw, renew, or exchange into something else. Best for the middle rungs, where growth matters more than committing to a lifetime payout right now.

A frequent structure for someone retiring at 65 pairs a SPIA for year-one income, a 5-year MYGA to cover roughly years six through ten, and a DIA that switches on around 80 to cover the tail end of a long retirement. That combination keeps guaranteed income flowing at every stage while still leaving money flexible in the middle years.

There is no universal right split between the three, since the correct mix depends on your other income sources, your health, your family history and how much flexibility you want to keep on hand. A licensed strategist can price all three against each other and show what a specific combination would actually pay before you commit a dollar, which tends to be a far more useful exercise than picking one product type in isolation.
