SPIA vs. MYGA: grow it or turn it into income
Both are fixed annuities from an insurer, but they solve opposite problems: a MYGA grows a lump sum and keeps your principal, a SPIA turns it into a guaranteed paycheck for life.
GetSure sells two fixed annuities that solve opposite problems. A MYGA — Multi-Year Guaranteed Annuity — is the savings tool: it grows a lump sum at a locked rate and keeps your principal, much like a CD from an insurer.
A SPIA — Single Premium Immediate Annuity — is the income tool: you hand over a lump sum and it converts into a guaranteed monthly paycheck for the rest of your life.
They're easy to confuse because both are "fixed annuities," but the trade is the difference. A MYGA keeps your money and pays interest. A SPIA gives up your money and pays income that cannot run out.
This guide lays them side by side — with real numbers — and helps you see which one fits the money you have in mind.
The short version
- A MYGA grows a lump sum at a guaranteed rate for a set term and hands the principal back at the end — its job is growth, and you keep your money.
- A SPIA spends that same lump sum to buy a fixed check for life — its job is income, and you give up the principal to get it.
- Everything else — how liquid it is, how it's taxed, who it fits — follows from that one trade: keep the principal, or convert it.
- A SPIA can pay more per year than a MYGA's interest alone, because of mortality credits — but only because the money is committed for life.
- They aren't rivals so much as stages: many savers grow in a MYGA first, then annuitize into a SPIA when the income is actually needed — and waiting usually buys a bigger check.
What each one actually is
Both take a single lump sum from one insurer. What happens to that lump sum is where they part ways.
One lump sum, two doorsThe same money goes to the same kind of insurer. A MYGA keeps your principal and pays interest; a SPIA converts your principal into income for life. Which door you pick is the whole decision.
MYGA — grow the lump sum
You commit money for a set term — usually 2 to 10 years — and the insurer pays a fixed rate that won't move while you hold it. The interest grows tax-deferred. At the end of the term your principal is yours: take it, roll it into a new contract, or 1035-exchange it. The principal stays intact the whole time.
SPIA — turn it into income
You hand the insurer a lump sum and, about a month later, a guaranteed check starts arriving — and keeps arriving for the rest of your life, no matter how long you live. There's no market assumption and no "hypothetical return," just one guaranteed number. In exchange, the lump sum is gone: you've traded principal for income.
The one difference that drives the rest
A MYGA keeps your principal and pays interest. A SPIA gives up your principal and pays income for life. Everything below — liquidity, taxes, who it fits — follows from that single trade.
The SPIA can pay more per dollar than the interest alone would suggest, because of mortality credits.
The insurer pools many lives; people who die earlier than expected leave money in the pool that subsidizes those who live longer. Every survivor earns a "credit" no CD or bond can replicate.
That pooling is why guaranteed lifetime income can out-pay an equally safe interest product — but it only works because you've committed the principal. Here's how a SPIA works, step by step.
The two side by side
Same issuer, same guarantee behind your money — opposite jobs. Here's the comparison that matters:
| MYGA | SPIA | |
|---|---|---|
| Issued by | Insurance company | Insurance company |
| Its job | Grow a lump sum | Turn a lump sum into income |
| What you get | A guaranteed growth rate for a set term | A guaranteed paycheck for life |
| How long it lasts | A set term — usually 2 to 10 years, then it ends | The rest of your life — it can't be outlived |
| Your principal | Stays intact, returned at term | Given up — converted to income |
| Liquidity | Accessible at term; free-withdrawal band yearly | None — the income stream can't be cashed out |
| If you die | The full balance passes to your heirs | Cash refund pays any unrecovered premium to heirs |
| Longevity risk | You can outlive the balance | Removed — the check keeps coming for life |
| What sets the number | The rate locked in for your term | Your age & sex plus rates on the day you buy |
| Reversibility | Ends on its own at term — nothing to undo | Permanent after a short free-look window |
| Taxation (non-IRA) | Interest taxed when you withdraw | Exclusion ratio splits each check (part tax-free) |
| Who it fits | Money you want to grow and still touch later | Money you want to turn into income you can't outlive |
The taxation row assumes non-qualified (after-tax) money. IRA money is taxed differently in both. How a SPIA is taxed · Qualified vs non-qualified, explained.
Where each one has the real edge
MYGA wins on flexibility
Your principal stays yours. If your plans change, you have it at the end of the term to spend, reinvest, or leave to heirs in full. Nothing about a MYGA is irreversible the way annuitizing is.
SPIA wins on income that can't run out
A MYGA can be outlived — the balance is finite. A SPIA removes that risk entirely: the check keeps coming for as long as you live, and mortality credits let it pay more than the interest alone would.
"What if I die early?" — the cash-refund answer
GetSure's default SPIA is single life with a cash refund: if you die before the payments have repaid your premium, your beneficiary gets the remainder as a lump sum. You get the highest income per dollar while still protecting your heirs against an early death. See all the payout options.
See it in real numbers
The trade-off is easier to weigh once you watch the same dollars go down each path. Take a saver with $200,000 and follow it three ways — grow it, turn it into income now, or grow it first and turn it into income later.
Path 1 — grow it in a MYGA
In early 2026 the strongest multi-year guaranteed rates run in the mid-5% range, and the very top 5-year listings sit above 6%. Put the $200,000 into a solid 5-year MYGA at 5.5% and it compounds, untouched, at a rate that can't move for the whole term.
Illustrative at a 5.5% five-year rate; strong 5-year MYGAs in early 2026 run near that, with the top listings above 6%. See this week's live MYGA rates →
Path 2 — turn it into income now
Hand the same $200,000 to a SPIA at age 65 and it stops being a balance and becomes a paycheck. At early-2026 rates, on a single-life payout with a cash refund, that's roughly:

Same $200,000, two different jobs
Down the MYGA path you still have your money — about $261,000 of it — and a decision to make in five years. Down the SPIA path you no longer have the $200,000, but you have a check that arrives every month for the rest of your life and can't run out. Neither number is "better." They answer different questions.
The question that decides it
Do you need income now, or growth you can still touch?
If you need a paycheck — money to live on that won't run out — a SPIA does that and a MYGA doesn't. If you want your money to grow safely and stay within reach, a MYGA does that and a SPIA doesn't. Almost every other detail is downstream of this one answer.
Two things usually settle it: your age, and whether the income is needed yet. Younger savers who don't need the money for years lean toward growing it first — locking in a SPIA's lifetime rate early often means a smaller check than waiting.
People at or near the point of needing reliable income lean toward the paycheck, because that's the problem they actually have. The closer you are to spending the money, the more a SPIA earns its place.
Which one fits you
There's no universally better product — the two solve different problems. A few real situations make the trade-off concrete:
The 62-year-old still growing money
Won't need this money for years and wants it to grow safely without market risk. A MYGA fits — lock a guaranteed rate, keep the principal, and decide later what to do with it.
The 70-year-old who needs a paycheck
Wants reliable income to live on that won't run out, no matter how long they live. A SPIA fits — the lump sum becomes a guaranteed monthly check, with a cash refund protecting heirs.
The saver who does both
Grows a lump sum in a MYGA through their 60s, then turns part of it into a SPIA paycheck when the income is actually needed. Growth first, income later.
Put simply: choose the MYGA when the job is to grow money you can still touch, and the SPIA when the job is to turn money into income you can't outlive.

Doing both — grow now, annuitize later
The two products aren't rivals so much as stages. A common plan is to grow a lump sum in a MYGA while you don't need the income, then convert some or all of it into a SPIA when you do.
Carry the same saver through it. She's 65, doesn't need income for a few years, and starts with $200,000:
Illustrative only. Moving from one annuity to another can often be done as a 1035 exchange; the right timing depends on your age, your need for income, and the rates available when you convert.
Notice what the wait bought. Annuitizing the $200,000 at 65 pays about $1,180 a month. Growing it for five years and annuitizing the larger balance at 70 pays about $1,720 a month — roughly 45% more income, for life, on the same starting money.
The same $200,000 buys a bigger check if you grow it firstAnnuitizing at 65 locks in a lifetime rate on $200,000. Growing it in a MYGA for five years and annuitizing ~$261,000 at 70 pays a materially larger check — because the balance is bigger and, at 70, the income is expected over fewer years.
Illustrative, single-life with a cash refund, male buyer as of early 2026; the MYGA grows at 5.5%. Waiting also means no income during the growth years and no guarantee of where rates land — the point isn't "always wait," it's that growth-then-income is a real, often stronger, third path.
You don't have to decide between growth and income today. You can grow first and turn on the paycheck when life calls for it — and you can annuitize part of the balance while leaving the rest growing.

What to ask before you decide
The choice between growing a lump sum and converting it is easier to settle with a few plain questions. Walk through these before you commit either way.
Do I need income from this money now, or not for years? If you need a paycheck, a SPIA does the job. If the need is years out, growing it in a MYGA first usually buys a bigger check later.
Might I need the lump sum back? A MYGA hands the principal back at term; a SPIA can't be cashed out once the free-look window closes. If a big one-off expense is likely, keep the money liquid.
Do I have to choose all-or-nothing? No. Many savers annuitize just enough to cover essential bills and keep the rest in a MYGA for flexibility. Ask what a partial split looks like.
Is the money IRA (qualified) or after-tax? It changes how each product is taxed and whether an RMD applies. Confirm the tax character before you move it.
What is the carrier's AM Best rating? It matters for both, but far more for a SPIA — that's a decades-long promise from one company. GetSure shows the rating on every quote.
What does a full quote look like today? A MYGA rate and a SPIA income figure cost nothing to pull, and seeing both real numbers side by side usually makes the decision obvious.
Frequently asked questions
Can I do both — grow in a MYGA and take income from a SPIA?
Yes, and many people do. A common approach grows a lump sum in a MYGA while income isn't needed, then converts part or all of it into a SPIA when it is.
You can also split a balance today: keep some in a MYGA for flexibility and turn the rest into a SPIA for guaranteed income. They're complementary, not either/or.
Can I turn my MYGA into a SPIA later?
Yes. When your MYGA term ends, you have the principal in hand and can use it to buy a SPIA.
Moving directly from one annuity to another is often handled as a 1035 exchange, which can keep the tax treatment clean for non-qualified money.
The SPIA rate you get is the rate available at that time, based on your age then — which is usually higher income than locking it in years earlier.
If I buy a SPIA, can I ever get my money back?
No — once the short free-look window closes, a SPIA is permanent. That irreversibility is the trade for the higher payout. The income stream itself can't be cashed out.
What protects your heirs is the payout option: GetSure's default cash-refund SPIA pays any unrecovered premium to your beneficiary if you die early. A MYGA, by contrast, returns your principal at term.
Why would a SPIA pay more than a MYGA's interest?
Two reasons. First, a SPIA check returns your own principal alongside interest, so the dollar amount is larger than interest alone.
Second, mortality credits: the insurer pools many lives, and those who die earlier subsidize those who live longer, so every survivor earns extra.
That's the engine a MYGA, CD, or bond can't replicate — and the reason you give up the principal to get it.
Which is safer, a MYGA or a SPIA?
Both are backed the same way — the issuing insurer's balance sheet, plus your state's guaranty association up to its limits. Neither has market risk to principal.
The practical difference is time: a SPIA is a decades-long claim on one insurer, so the carrier's financial-strength rating matters even more. GetSure shows each carrier's AM Best rating as a transparency badge.
Does inflation hurt a SPIA more than a MYGA?
A fixed SPIA paycheck stays the same dollar amount for life, so its purchasing power erodes over a long retirement. You can add an increasing-payment rider that steps the check up each year, but it starts the income materially lower.
A MYGA sidesteps this differently: its term is short, so you re-price at current rates when it ends. How a SPIA handles inflation.
I'm under 59½ — does that change things?
Usually, yes — toward waiting. SPIAs are built for people at or near retirement who need income now; a lifetime income started young locks in a smaller check and ties up money you may need for other things.
Taking money out of either annuity before 59½ can also trigger a 10% IRS penalty on the taxable portion. For money you won't touch for years, growing it in a MYGA first is often the cleaner path.
How much money do I need to start one?
Both have modest minimums that vary by carrier — many MYGAs and SPIAs start in the range of a few thousand to $10,000 or more of premium. There's no need to commit a whole nest egg to either: a MYGA can hold part of your savings while the rest stays in the bank, and a SPIA is usually best sized to cover just your essential monthly bills. The exact minimum depends on the carrier and product; a quote shows it.
Is the MYGA rate I see locked for the whole term?
Yes — a MYGA's defining feature is a single rate guaranteed for the entire term you choose. It doesn't reset annually the way some other fixed annuities do. When the term ends you're re-quoted at whatever rates are available then, and you can renew, take the money, or move it into a SPIA. A SPIA works the same way in spirit: the monthly amount is fixed on day one and never changes for life.
