TIAA Lifetime Income: Single Life vs. Joint Survivor — Which Should You Choose?
If you're married and considering TIAA lifetime income, you may assume the obvious choice is a 100% joint-survivor annuity.
After all, you want to make sure your spouse is protected if you die first.
In many cases, that makes perfect sense.
But not always.
I recently encountered two married couples where, after reviewing their circumstances and comparing the actual TIAA illustrations, a single-life annuity with a 15-year guaranteed period made more sense for them than the 100% joint-survivor option.
These situations are not the norm.
But they demonstrate an important point:
Don't automatically select the default lifetime-income option without comparing the alternatives.
First, Understand the Basic Choices
TIAA Traditional generally provides several ways to structure lifetime income.
Single-Life Annuity
A single-life—or one-life—annuity provides income for as long as the participant lives.
Because the income is based primarily on one life rather than two, the initial payment will generally be higher than an otherwise comparable joint-life option.
But there is an obvious tradeoff.
Once the participant dies, lifetime payments stop unless a guaranteed period is still in effect.
Joint-Life Annuity
A joint-life—or two-life—annuity provides lifetime income covering the participant and an annuity partner, typically a spouse.
With a 100% survivor option, the surviving spouse can continue receiving the full applicable lifetime payment after the participant dies.
Because TIAA is potentially committing to payments over two lifetimes, the initial payment is generally lower than with a comparable single-life option.
TIAA specifically offers both one-life and two-life retirement-income choices.
Single Life With a Guaranteed Period
There is also a middle ground.
TIAA allows a guaranteed period—generally 10, 15, or 20 years—to be added to lifetime-income elections, subject to applicable terms.
For example, suppose you select:
Single life with a 15-year guaranteed period.
If you live for 30 years after beginning the annuity, you continue receiving payments for all 30 years.
The 15-year guarantee does not mean your payments stop after 15 years.
Instead, it provides protection if you die early.
If you die five years after payments begin, your beneficiary generally receives the payments for the remaining 10 years of the guaranteed period. After the guaranteed period has expired, however, there is no continuing lifetime payment to that beneficiary solely because of the guarantee.
That distinction becomes very important.
Scenario #1: The Couple Already Had Substantial Life Insurance
The first case involved a married couple with substantial retirement assets.
Initially, they were not particularly interested in TIAA lifetime income.
Then we ran the TIAA Retirement Income Illustrator.
The husband's payout rate was approximately:
9.25%
That got my attention.
At that level, I believed lifetime income deserved serious consideration as part of their overall retirement-income plan.
They agreed.
The next question was:
Which lifetime-income option should they choose?
Their Initial Choice Was 100% Joint Survivor
The husband naturally assumed they would select a 100% joint-survivor option.
That's a perfectly logical starting point.
If he died first, his wife would continue receiving lifetime income.
But before making the election, we looked more closely at their complete financial situation.
One detail became particularly important:
He already had a substantial life insurance policy protecting his wife.
They also had significant assets outside the annuity.
That meant we needed to ask a different question:
If she is already financially protected if he dies first, how much additional income are they giving up today to purchase another layer of survivor protection through the annuity?
That's where the comparison became interesting.
Single Life Produced Meaningfully More Income
We compared the 100% joint-survivor option with:
Single life + 15-year guaranteed period
The single-life option produced a noticeably larger payment.
That shouldn't be surprising.
The joint-survivor option potentially has to provide income until the second spouse dies.
The single-life option is based on one lifetime, with the 15-year guarantee providing a defined period of beneficiary protection.
The couple already had another significant survivor resource:
Life insurance.
They also had substantial financial assets.
So instead of automatically purchasing maximum survivor protection through the TIAA annuity, they decided to take the larger single-life payment while retaining the 15-year guarantee.
For their situation, they preferred that tradeoff.
Think of Survivor Protection as Something You're Purchasing
This is a useful way to think about the decision.
When you choose a joint-survivor annuity instead of a single-life annuity, you are essentially accepting a lower current payment in exchange for additional protection if one spouse outlives the other.
That protection has value.
But it also has a cost.
Suppose, hypothetically, the choices are:
| Lifetime-Income Option | Annual Income |
|---|---|
| Single Life + 15-Year Guarantee | $50,000 |
| 100% Joint Survivor | $43,000 |
The difference is:
$7,000 per year
That $7,000 isn't necessarily being “lost.”
It is effectively part of the economic cost of providing lifetime survivor protection.
The question becomes:
Does this household need that additional protection badly enough to accept $7,000 less income every year?
For many couples, the answer will absolutely be yes.
For others, perhaps not.
Scenario #2: Significant Health Issues Changed the Analysis
The second situation was more difficult.
Again, this involved a married couple.
The husband was evaluating TIAA lifetime income, and his initial illustration used a 100% joint-survivor benefit for his wife.
That's where most married couples naturally begin.
However, there were two important facts.
His wife was:
Older than he was
Dealing with significant health issues
The couple openly discussed those circumstances as part of their planning.
Given the situation, we decided it was worth comparing the joint-survivor option with a single-life option.
Why Longevity Matters
A 100% joint-survivor option provides valuable protection when there is a meaningful possibility that the spouse will substantially outlive the participant.
But in this couple's situation, their expectations regarding longevity were different.
We therefore compared:
100% joint survivor
with:
Single life + 15-year guarantee
Once again, the single-life option produced meaningfully more current income.
That changed the discussion.
If the wife died first, the husband's lifetime income under his single-life election would continue for his lifetime.
And if the husband died during the 15-year guaranteed period, the designated beneficiary could receive payments for the remainder of that guaranteed period.
Given their circumstances, they preferred the higher single-life payment plus the defined guarantee period rather than paying for 100% lifetime survivor protection.
This Is Not About Predicting Who Will Die First
This distinction is extremely important.
Nobody knows precisely how long either spouse will live.
Health conditions can affect planning assumptions, but they don't give us certainty.
Someone with serious health issues can live much longer than expected.
A healthy spouse can die unexpectedly.
So this analysis should never be reduced to:
“We think one spouse will die first, so choose single life.”
That's too simplistic.
Instead, consider:
Ages
Current health circumstances
Other assets
Life insurance
Social Security
Pensions
Spending needs
Beneficiaries
The difference in TIAA payments
The household's tolerance for survivor-income risk
Then compare the alternatives.
Life Insurance Can Change the Equation
The first case illustrates an important concept sometimes called pension maximization.
The basic idea is simple.
Suppose the single-life annuity pays considerably more than the joint-survivor option.
Rather than automatically accepting the lower joint payment, a household can evaluate whether existing life insurance—or potentially another pool of assets—already provides sufficient protection for the surviving spouse.
For example:
Joint-Survivor Strategy
Lifetime income:
$45,000 annually
Surviving spouse continues receiving the applicable lifetime benefit.
Single-Life Strategy
Lifetime income:
$53,000 annually
Existing life insurance:
$750,000 death benefit
Now the household has to evaluate whether the additional $8,000 of annual income today, combined with the existing life insurance protection, better serves its goals.
There is no universal answer.
But there should be a comparison.
Don't Ignore the Guarantee Period
A guarantee period can sometimes make the single-life option more attractive to a married couple.
Suppose a participant selects:
Single life + 15-year guarantee
and dies in year three.
The beneficiary can generally receive payments for the remaining 12 years of the guarantee period.
That does not provide the same protection as a joint-survivor annuity.
The spouse could live another 30 years.
After the guarantee expires, the payments would end.
But the guarantee can reduce one of the biggest concerns associated with single-life income:
“What if I annuitize the money and die shortly afterward?”
For some households, that protection combined with other assets may be sufficient.
A Guarantee Period Is Not the Same as Joint Survivor
This is worth emphasizing.
These options solve different problems.
100% Joint Survivor
Designed to provide lifetime income across two lives.
Single Life + 15-Year Guarantee
Designed to provide lifetime income for one person, while guaranteeing payments for at least the specified period if death occurs early.
The joint-survivor option protects against the risk that the spouse lives a very long time.
The guarantee period primarily protects against the participant dying relatively soon after the annuity begins.
Those are different risks.
Calculate the Cost of Survivor Protection
One of the most useful exercises is simply to calculate the difference between the two payments.
Suppose the Retirement Income Illustrator shows:
Single Life + 15-Year Guarantee: $5,200/month
100% Joint Survivor: $4,650/month
Difference:
$550 per month
or:
$6,600 per year
Now ask:
What are we receiving in exchange for giving up $6,600 annually?
The answer is additional lifetime protection for the surviving spouse.
Then look at the rest of the household.
Does the surviving spouse already have:
Their own Social Security?
Their own pension?
Their own IRA?
A Roth IRA?
Taxable investments?
Life insurance proceeds?
Other guaranteed income?
If the answer is no, the joint-survivor benefit may be extremely important.
If the answer is yes, it deserves a more detailed comparison.
Social Security Matters Too
Don't analyze the TIAA annuity in isolation.
When one spouse dies, household Social Security income often changes.
The surviving spouse generally does not simply continue receiving both Social Security benefits indefinitely.
That means the household may already face an income reduction after the first death.
If the surviving spouse would lose:
One Social Security check
Part of household pension income
TIAA income
the joint-survivor annuity may be especially valuable.
Conversely, substantial life insurance and liquid investments may provide enough replacement income that the household is comfortable accepting more TIAA income while both spouses are alive.
Taxes Can Change After the First Death
There is another planning issue married couples sometimes overlook.
After one spouse dies, the survivor may eventually file taxes as a single taxpayer.
That can create a very different tax environment.
The surviving spouse may have:
Similar retirement income
Similar RMDs
Fewer tax deductions
Narrower tax brackets
That can increase the effective tax burden on the survivor.
This is another reason not to remove survivor income casually.
The entire household plan matters.
Don't Choose Based Solely on the Highest Payout
Just as I don't recommend automatically choosing joint survivor, I also don't recommend choosing single life merely because the payment is higher.
Of course it is higher.
You're purchasing less lifetime protection.
The correct comparison isn't:
“Which option pays me the most?”
It's:
“Which option gives our household the best combination of income and protection?”
That's a very different question.
When a Single-Life Option May Be Worth Considering
For a married couple, single life with a guaranteed period may deserve consideration when:
There is substantial existing life insurance
The surviving spouse has significant independent assets
Both spouses have substantial retirement savings
The difference in payments is significant
One spouse has materially different longevity circumstances
The surviving spouse has sufficient guaranteed income elsewhere
The couple values greater income while both are alive
A guarantee period provides sufficient additional protection for their goals
None of these automatically means single life is the correct choice.
They mean it is worth running the illustration.
When Joint Survivor May Be More Appropriate
A joint-survivor option may be particularly important when:
The spouse depends heavily on the participant's retirement income
There is little life insurance
Liquid assets are limited
The spouse has little retirement savings
One spouse has substantially higher Social Security income
The spouse could face a very long retirement alone
Guaranteed lifetime income is a high priority
The couple does not want survivor income dependent on investment markets
For many married couples, these factors will outweigh the higher initial single-life payment.
Run Every Option Through the Retirement Income Illustrator
This is the biggest takeaway.
Don't assume.
Run the numbers.
If you're married and considering lifetime income, compare at least:
Single life
Single life with 10-year guarantee
Single life with 15-year guarantee
Single life with 20-year guarantee
100% joint survivor
Other available survivor percentages that fit your circumstances
Keep the amount being annuitized and the proposed start date consistent so you can see the actual cost of each protection feature.
TIAA currently describes one-life, two-life and guaranteed-period elections among its available TIAA Traditional retirement-income choices.
Remember: The Election Is a Major Long-Term Decision
Lifetime-income elections deserve careful analysis because annuitization changes what you can do with those assets.
Once money has been committed to a lifetime-annuity structure, you should not assume you can simply reverse the decision later.
That makes the survivor election particularly important.
Before finalizing it, both spouses should understand:
The initial payment
What happens if the participant dies first
What happens if the spouse dies first
What happens if both die during the guarantee period
What happens after the guarantee period expires
What assets remain liquid
What income the surviving spouse would have from other sources
Questions Married Couples Should Ask
Before choosing a TIAA lifetime-income option, consider:
How much more does single life pay?
How much less does 100% joint survivor pay?
What happens financially if I die first?
What happens if my spouse dies first?
How much life insurance do we have?
How much does each spouse have in separate retirement assets?
What Social Security income survives the first death?
What other pensions continue?
Would a 10-, 15-, or 20-year guarantee provide enough protection?
How much income does the surviving spouse actually need?
What happens to taxes after the first spouse dies?
Are we comfortable giving up liquidity for this income?
Answer those questions before checking the box.
Frequently Asked Questions
Should married couples always choose a joint-survivor TIAA annuity?
No. A joint-survivor option can provide valuable lifetime protection for a spouse, but the appropriate choice depends on the household's other assets, insurance, income sources, ages, goals and circumstances.
Does single life pay more than joint survivor?
Generally, a single-life option will provide a higher initial payment than a comparable joint-life option because TIAA is providing lifetime income based primarily on one life rather than potentially two.
What does a 15-year guarantee mean?
If the participant dies during the 15-year guaranteed period, payments can continue to the beneficiary for the remaining portion of that period. If the participant lives beyond 15 years, the participant's lifetime payments continue; the guarantee does not terminate their lifetime income.
Is a 15-year guarantee the same as a joint-survivor benefit?
No. A joint-survivor annuity can continue income for the surviving spouse's lifetime. A 15-year guarantee only protects payments through the remainder of that 15-year period if death occurs during it.
Can life insurance replace a joint-survivor annuity?
Life insurance can be considered as part of the survivor-income analysis, but whether it provides sufficient protection depends on the death benefit, premiums, policy status, other assets and the surviving spouse's projected needs.
Should health affect the annuity election?
Known health circumstances can be relevant to retirement-income planning, but longevity is inherently uncertain. Health should be considered alongside the couple's broader financial resources rather than treated as a prediction of lifespan.
Is the highest TIAA payout always the best option?
No. Higher income often comes with less survivor protection. The goal is to determine which combination of current income, survivor benefits and other assets best fits the household.
Final Thoughts
For most married couples considering TIAA lifetime income, it is natural to start with the joint-survivor option.
But don't stop there.
In the two real cases I recently encountered, a single-life annuity with a 15-year guaranteed period made more sense for those particular couples.
In one case, substantial life insurance and other assets provided significant protection for the spouse.
In the other, the couple's ages, health circumstances and financial resources changed the value they placed on lifetime survivor protection.
In both situations, the single-life option produced meaningfully more income.
That doesn't make single life better.
And it doesn't make joint survivor better.
It means the correct answer depends on the household.
Before initiating TIAA lifetime income, exhaust the options.
Run the Retirement Income Illustrator several different ways.
Look at the dollar difference.
Then ask what you're actually buying with the lower payment.
Sometimes the survivor protection will be worth every dollar.
Sometimes the household may already have enough protection elsewhere.
You won't know until you run the numbers.
