One calculation tells you whether the offer is generous. Four factors decide the rest. And two tax traps catch people who get the decision right but the mechanics wrong.

If your employer has offered a choice between a lump sum and a monthly pension, you are making a decision you cannot undo. Most articles resolve it with a philosophy - control versus certainty. That is not much help. Here is the arithmetic you can actually run, plus the four factors that change the answer.
This calculation tells you how generous the offer is, and the answer depends on how long the pension would be paid.
Here is the return a $500,000 lump sum must earn, after fees, to pay the same $30,000 a year for as long as the pension would:
Our calculation: the annual return at which $500,000, drawn down by $30,000 a year, lasts exactly that long. Hypothetical; it excludes taxes, fees and cost-of-living increases. A survivor option or a cost-of-living adjustment lengthens or raises the payments, which raises the break-even.
So the real questions are how long you, and a spouse on a survivor option, are likely to live, and whether you could reliably earn the break-even return after fees. The longer the likely payout, the stronger the pension. A second check is market price: ask what an insurer would charge for the same lifetime income as an immediate annuity. If it would cost more than your lump sum, the plan’s offer is the better value.
Discipline matters as much as the math. If the realistic alternative is leaving the money in a money market fund or panic-selling in the next downturn, the pension’s discipline is worth real money that no spreadsheet captures.
1. Your spouse. A single-life annuity stops at your death. A joint and survivor option pays less while you are alive and continues a percentage to your survivor. How much a 50% joint and survivor election reduces the payment depends on both ages and your plan’s factors; your election packet shows it in dollars. If you are the primary earner and your spouse has meaningfully lower Social Security, that reduction is buying fifteen or twenty years of their income.
2. Your health and family longevity. Pensions are longevity insurance - they pay off if you live a long time. If you would not bet on reaching 85, the math tilts firmly toward the cash.
3. How much guaranteed income you already have. If Social Security already covers your essential expenses, additional guaranteed income has lower marginal value. If it does not, the pension is filling a real gap.
4. Whether you actually want to manage the money. Drawing down a $1.4 million rollover across thirty years is a different psychological exercise from receiving a check. Neither answer is wrong; knowing which you are is what matters. Texas teachers: moving 403(b) or TRS money.
Choosing the annuity means trusting your former employer’s plan for decades. The Pension Benefit Guaranty Corporation insures private-sector pensions, but only up to a statutory limit.
For most retirees that limit is comfortably above their benefit and this is academic. For higher-earning executives it is not, and reviewing the plan’s funded status: disclosed annually in its Form 5500 filing under ERISA - is a reasonable step before relying on it for thirty years.
Take the cash outright and it is generally all taxable that year. Rolling it directly into a traditional or rollover IRA defers taxation until withdrawal. A direct rollover is not a taxable distribution.
A lump sum can raise your Medicare premiums two years later. Large taxable income triggers Medicare income-related monthly adjustment amounts (IRMAA) on Part B and Part D. Because IRMAA is assessed on income from two years prior, a distribution taken in 2026 affects your 2028 premiums. A direct IRA rollover generally avoids this entirely, which is precisely why the mechanics matter as much as the decision.
Some plans allow a partial election. Where they do not, a lump sum rolled into an IRA can still be divided by purpose afterwards, a growth allocation, an income allocation, and potentially a portion used to purchase guaranteed income if that is what you actually wanted from the pension.
That last piece is where a fixed index annuity or an immediate annuity sometimes fits, not as a replacement for the whole decision, but as a way to rebuild an income floor from part of the money while keeping the rest flexible. Worth reading the sequence of returns risk page first, because that is the risk an income floor is actually addressing.
There is no universal answer, and anyone who gives you one without knowing your situation is guessing. The decision turns on four things: the break-even return your plan offers, whether you have a spouse who would need survivor income, your health and family longevity, and how much guaranteed income you already have from Social Security. The same offer can be poor for a single 65-year-old in average health and excellent for a married couple in their early sixties with longevity in the family.
Work out the break-even return: the annual return the lump sum must earn, after fees, to pay the same income for as long as the pension would. Dividing the pension by the lump sum gives a payout rate, not a return; $30,000 on $500,000 is 6%, but because a pension stops when payments end, the break-even is lower: about 1.8% over 20 years, 3.4% over 25 and 4.3% over 30. The longer you and a surviving spouse are likely to collect, the stronger the pension. You can also compare the lump sum with what an insurer would charge for the same lifetime income.
Partly. The Pension Benefit Guaranty Corporation insures private-sector pensions up to a statutory limit. For a 65-year-old starting a straight-life annuity in 2026, the PBGC maximum guarantee is $7,789.77 a month, about $93,477 a year. Benefits above that cap are not insured and represent an unsecured claim against the plan sponsor. If your pension exceeds the limit, reviewing the plan's funded status in its Form 5500 filing is a reasonable step before relying on it for decades.
A single-life annuity pays the full amount while you are alive and stops at your death. A joint and survivor option pays less while you are alive and continues a percentage to your surviving spouse. How much a 50% joint and survivor election reduces the payment depends on both spouses' ages and the plan's factors, and your election packet shows it in dollars. That is real money, and it is also insurance against your spouse outliving you by fifteen or twenty years on significantly less income. If you are the primary earner and your spouse has meaningfully lower Social Security, the reduction is often worth it.
Yes, and it surprises people. A large lump sum raises your modified adjusted gross income in the year you receive it, which can trigger Medicare income-related monthly adjustment amounts, or IRMAA, on Part B and Part D premiums. Because IRMAA is assessed on income reported two years prior, income in 2026 affects premiums in 2028. Rolling the lump sum directly into an IRA generally avoids this, since a direct rollover is not a taxable distribution.
Not if it is rolled directly into a traditional or rollover IRA, which defers taxation until you withdraw. Taking the cash outright generally makes the full amount taxable in that year, which can be a very expensive choice. Under SECURE 2.0, required minimum distributions generally begin at age 73 for those born between 1951 and 1959, and age 75 for those born in 1960 or later.
It can. Lump sums are calculated using interest rate assumptions, when rates are higher, the plan needs less principal today to fund the same future payments, so lump sums shrink. Many plans use published segment rates on a trailing average, which means the month you commence benefits can measurably change the figure. This is worth confirming with your plan administrator rather than assuming a generic rule applies.
Some plans allow partial elections, and some do not. Where the plan is all-or-nothing, a lump sum rolled into an IRA can still be divided by purpose afterwards, a growth allocation, an income allocation, and potentially a portion used to purchase guaranteed income if that matters to you. Treating it as an all-or-nothing philosophical choice is usually a mistake when the money can be split by function.
