How do I weigh a pension lump sum vs. an annuity?

A pension lump sum vs. annuity starts with $16K

Taking the lump sum because generic advice says to “keep control of your money,” then spending it at a fixed 4 percent, can leave real income on the table. On $400K, 4 percent is $16K annually. Against a $2,700 monthly pension, or $32,400 annually, that gives up $16,400 annually, about $196,800 over 12 years before growth.

Use the same math for both choices. Divide the annual pension by the offered lump sum: $32,400 ÷ $400K = 8.1 percent. Then put that rate beside a guardrail withdrawal starting rate from the same $400K, such as 5 percent, before deciding how much control, inheritance value, and tax flexibility matter.

Tolleson Wealth Management uses a quick test: if the pension payout rate is two or more percentage points above the guardrail starting rate you would take from the same money, price the annuity first. If the gap is smaller, keeping the lump sum often costs less in first-year income and may be worth the added flexibility.

That test does not price health, inflation, or the pension’s financial backing. A shorter life expectancy, a pension without a cost-of-living raise, or a government plan outside Pension Benefit Guaranty Corporation coverage can change the result.

Can I compare a lifetime check, a period-certain check and a rollover on the same terms?

You can compare these pension forms by putting monthly income, heirs, tax treatment, and who bears market and longevity risk on one page. A single-life annuity usually pays the most, a survivor or 10-year-certain form trades some income for beneficiary protection, and a direct IRA rollover preserves the remaining balance for heirs.

The table separates choices that are often mixed together in a pension election packet. The monthly figures vary by plan, age, and survivor percentage, but the ownership and tax differences do not.

A married participant generally defaults to a joint-and-survivor annuity; federal rules usually require a spouse’s written consent to elect a single-life benefit or lump sum. A divorced reader should first check whether a qualified domestic relations order assigns part of the benefit to an ex-spouse. Monthly pension checks are generally ordinary income, while a direct rollover does not create tax when the money moves.

Many private pensions pay a flat amount for life, so read the summary plan description for any cost-of-living feature. The PBGC covers most private-sector pensions up to legal limits, but it does not cover government plans. An IRA holding the rolled-over $400K can be worth less than $400K after a bad stretch of markets, while the pension check does not move with markets.

The pension forms that change the check

Tax and risk do not sit in the same place

At 73 the pension has to start: one deadline in Pavel’s numbers

For illustration, hypothetical Pavel, 71, is a divorced retired pharmacist with two adult children and nearly all his savings in a $2.1M traditional IRA. He finds a deferred pension from a hospital job he left at 58: $400K now or $2,700 monthly for life. That is $32,400 annually and an 8.1 percent payout, because $32,400 ÷ $400K = 8.1 percent.

A guardrail draw starting at 5 percent would pay Pavel $20K annually from the lump sum. The pension produces $12,400 more in year one. Ignoring growth and inflation, $400K ÷ $32,400 equals about 12 years, so the annuity checks match the lump sum by his early 80s.

His choice has a deadline. A retired participant’s plan benefit generally must begin by April 1 of the year after reaching 73; the start age is 75 for people born in 1960 or later. The IRS sets required minimum distribution rules, and Pavel’s election needs to fit the date stated in his pension paperwork.

The less obvious issue is tax room. If Pavel directs the $400K into his IRA, it becomes $2.5M. His first required minimum distribution at 73 rises by about $15,100, calculated as $400K ÷ 26.5 using the IRS age-73 factor and ignoring growth. That is less than half of the $32,400 the annuity adds to taxable income every year.

At 71 and 72, the rollover leaves Pavel more room to examine a Roth conversion strategy before required distributions begin. Watch Medicare too. Pavel is already enrolled, and IRMAA reads MAGI from two years earlier, so conversion income at 71 and 72 sets his Part B premiums at 73 and 74. But he gives up $12,400 of first-year income and the lifetime protection of the larger pension check. Our calculator can run the payout-rate and withdrawal comparison with your own figures.

For someone 10 to 15 years from retirement, Pavel’s deadline is the end of a longer chain. Look for age 65 and age 73 in the table, where the two choices begin to produce different Medicare and distribution effects.

Why an IRA rollover changes the RMD

What should I gather and when, starting in my late 50s?

Start with the summary plan description and a benefit estimate showing the lump sum and every annuity form. Get both from HR or the plan administrator, and ask for a fresh estimate annually. Add your latest IRA and 401(k) statements from the custodian, your Social Security earnings record from your online SSA account, and last year’s tax return from your files or CPA.

Lump sums move with the plan’s interest-rate assumptions and your age, so an estimate at 58 can differ sharply from one at 63. Ask the plan how it sets the lump sum and when it resets the rate. A separate retirement paycheck checklist can help put the pension beside Social Security and account withdrawals.

Acting too early can be costly. A worker who rolls money to an IRA at 55 and withdraws before 59½ can owe the 10 percent additional tax. Pension-plan payouts may avoid it if you separated from service in the calendar year you turned 55 or later. Acting too late has a different cost: election notices often arrive 30 to 180 days before the annuity starting date, and the lump sum is commonly unavailable after checks begin.

Taking a $400K check rather than using a direct rollover creates another trap. The payer generally withholds $80K, and you must replace that $80K from other money within 60 days for the whole amount to reach the IRA without current tax. Ask for a direct trustee-to-trustee rollover when a rollover is your choice.

The catch-up years give you more room to decide. The IRS limit for 2026 allows an $8,000 catch-up for ages 50 and older in a 401(k), 403(b), governmental 457, or TSP. Ten years from 50 through 59 adds $80K before growth; the $11,250 catch-up at ages 60 through 63 adds another $45K. That $125K cushion can reduce the pressure to make a pension election solve every problem.

Put these questions to the plan administrator, CPA, or advisor before you elect:

Request the full benefit estimate first, calculate the payout rate second, and then compare it with a guardrail starting rate from the same sum. Check survivor and heir needs before running the tax and IRMAA effect for the two years before Medicare and the required distribution start date. Tolleson Wealth Management can put those pages beside each other without treating the largest number in the packet as the answer.

Paperwork that makes the offer comparable

The timing errors hidden in a pension packet

• Which annuity forms and survivor percentages does the plan offer?
• What interest rate and mortality table set my lump sum, and when do they reset?
• Does the pension include a cost-of-living raise?
• Can I split the benefit into part lump sum and part annuity?
• How would each choice change MAGI during IRMAA lookback years?

Which option fits me: lifetime check, survivor version or rollover?

A single-life check can fit a single person in good health whose only dependable income is Social Security and whose pension payout rate is at least two percentage points above a guardrail start. A survivor or period-certain form fits a married reader or someone who wants a child protected for 10 years.

A direct rollover can fit someone like Pavel, who already has steady income, wants assets to pass to heirs, and needs more control over taxable income before Roth conversions. Tolleson Wealth Management would weigh those facts before favoring a larger check or a larger account balance.

Tolleson Wealth Management prices both checks before the packet goes back

Tolleson Wealth Management advisors put the plan’s monthly offer beside a guardrail withdrawal from the same lump sum and show how each changes taxes, MAGI, and what heirs may receive, using a screen-share call wherever you live. How Tolleson Wealth Management is paid is explained in writing before assets move. People with $500K or more in investable assets can start by sending the request form.
