Pension lump sum vs monthly annuity: how to choose

Illustrative examples, education not advice.

In plain words

If you have a traditional (defined benefit) pension, you may be offered a choice when you retire or leave:

A monthly annuity. A fixed check for the rest of your life, and possibly your spouse’s life.
A lump sum. One payment today, which you can roll into an IRA and invest yourself.

The two are meant to be roughly equal in value on paper. The plan calculates the lump sum by taking your future monthly payments and discounting them back to today using interest rates and life expectancy tables set by federal rules. When interest rates are higher, lump sums are usually smaller, and when rates are lower, they are usually larger.

The choice is often permanent. Once you take the lump sum, the pension promise is gone.

How it helps real people

A pension is one of the most valuable things a worker can have: guaranteed income that doesn’t depend on markets and that you can’t outlive. Wealthy retirees often pay insurers to create exactly this. Before giving it up, it’s worth knowing what it would cost to buy back.

At the same time, a lump sum can make sense for people who need flexibility, who have health concerns, or who want to leave money to heirs. Understanding both sides lets you choose on purpose, not by default.

A worked example

Illustrative. Not a quote or projection.

Frank, 62, can take a pension of $2,400 a month for life with no cost-of-living increase, or a lump sum of $390,000. His wife, Irene, is 60 and has a small IRA.

Step 1: what would it cost to buy the same income? An illustrative quote for a single-life income annuity paying $2,400 a month at 62 is about $440,000. So the pension is worth more than the lump sum in the open market.

Step 2: what would the lump sum need to earn? To pay $2,400 a month for 25 years, the $390,000 would need to earn about 5.6% a year after fees, and Frank would bear the risk of a bad market and of living past 87.

Step 3: think about Irene. A joint-and-100%-survivor option pays $2,100 a month for as long as either lives. If Frank chose the single-life option and died first, Irene’s income would drop sharply.

Choice	Illustrative result
Single life, $2,400 a month	Highest check, stops at Frank’s death
Joint and 100% survivor, $2,100 a month	Lifetime income for both
Lump sum, $390,000 to an IRA	Control and legacy, with market and longevity risk

Frank and Irene choose the joint-and-survivor option. With Social Security, it covers their essential bills for both lives. Irene’s IRA becomes their flexible money.

Who it’s for

The annuity may suit you if:

you’re in good health or your family tends to live long;
you want a reliable income floor and don’t want to manage investments;
you’re married and want to protect a surviving spouse;
the pension’s payout is better than what you could buy from an insurer.

The lump sum may suit you if:

you have serious health issues that shorten life expectancy;
your essentials are already covered by other lifetime income;
you want to leave money to children or charity;
you have reason to worry about the plan’s finances and your benefit exceeds the federal guarantee.

Who it’s not for

A lump sum is a poor fit for anyone likely to spend it early or invest it without a plan.
The annuity is a poor fit for someone who badly needs flexible cash for debts or a business, or who has a short life expectancy without a survivor to protect.

Risks and trade-offs

Inflation. Most private pensions have no cost-of-living increase, so buying power falls each year. A lump sum invested for growth can keep pace but adds risk.
Plan risk. If a private plan fails, the Pension Benefit Guaranty Corporation (PBGC) insures benefits up to a yearly limit that depends on your age and payout form. Many pensions fall within the limit; very large ones may not.
Tax. Monthly payments are taxed as ordinary income. A lump sum is taxable if you take it as cash, and 20% is usually withheld, but a direct rollover to an IRA keeps it tax-deferred.
Spousal rights. Federal law generally requires a spouse’s written consent before a married worker can choose a lump sum or a single-life annuity.
Behaviour. Large lump sums attract poor advice and impulse spending.

Common mistakes

Comparing the lump sum with nothing. Compare it with what the same income would cost from an insurer.
Choosing single-life to get a bigger check without a plan for the survivor.
Taking the cash instead of a direct rollover, which can trigger a large tax bill and withholding.
Ignoring the timing of rates. Lump sums use rates set in advance; a change in rates can make the lump sum bigger or smaller depending on when you retire.
Forgetting other income. If Social Security and the pension cover essentials, more of your savings can go toward growth.

FAQs

Can I take part as a lump sum and part as income?

Some plans allow a partial lump sum. Many don’t. Ask your plan administrator.

Is a lump sum offer a sign my plan is in trouble?

Not necessarily. Employers often offer lump sums to reduce plan size and costs. Check the plan’s annual funding notice.

Can I buy my own annuity with the lump sum later?

Yes, but the price may be higher than what the pension would have paid, and rates will change by then.

What about government pensions?

Many public pensions don’t offer lump sums, often have cost-of-living increases, and are not covered by the PBGC. Rules vary by plan.

Should I take a life insurance policy instead of the survivor option?

This is called pension maximization. It can work, but only if the policy is affordable, permanent enough and in force when needed. It carries real risk if the policy lapses.
