Your employer is offering to swap your monthly pension for a single check. The offer letter makes it look like a windfall. It is not a windfall — it is a trade, and the plan's actuaries priced it. Your job is to figure out whether the price is fair for your life, your health, and your household.
This is a different question from whether you need an annuity on top of a pension you're keeping — if that's your situation, start with our guide to how much of your savings belongs in an annuity. Here, the pension itself is on the table, and the framework below walks through how to decide.
What a Lump Sum Offer Actually Is
A lump sum buyout is the present value of your promised pension payments: the plan projects every check it expects to send you, then discounts that stream back to today using interest rates and mortality tables prescribed by the IRS. It is the plan's math for what the promise costs, not a bonus for taking cash.
That math has a consequence most offer letters don't emphasize: the number moves. When the prescribed rates rise, the same monthly pension converts to a smaller lump sum; when rates fall, the lump sum grows. Plans recalculate on a schedule, so an offer is a point-in-time figure, not a standing price. Before deciding anything, ask the administrator which rates apply and when they reset.
The Two Deals, Side by Side
| Dimension | Keep the pension annuity | Take the lump sum |
|---|---|---|
| Income guarantee | Monthly check for life, no market risk | None unless you buy income with it |
| Longevity risk | Carried by the plan — payments never outlive you | Carried by you, unless you annuitize part of it |
| Inflation | Many private pensions pay a level amount with no cost-of-living increases | You can invest for growth or buy inflation-aware income |
| Control and flexibility | None — the election is fixed once payments start | Full control over investing, spending, and timing |
| Legacy | Typically ends at death (or continues to a spouse under joint elections) | Unspent balance passes to your beneficiaries |
| Backstop | PBGC insurance up to legal caps for most private plans | You manage it; a purchased annuity relies on carrier strength plus state guaranty limits |
| Behavioral risk | None — you can't overspend a paycheck you don't hold | Real — a large balance invites large withdrawals |
The One Test That Puts a Price on It
Strip away the emotion and the decision has a market test: what would your lump sum buy as a commercial income annuity with the same shape as your pension — single life if you're single, joint and survivor if you're married?
Run your age and the offered lump sum through the live SPIA income estimates and the annuity payout comparison tool. If the pension's monthly check is clearly higher than what insurers will pay for the same money, the pension is the richer deal — old plans often carry generous internal assumptions no carrier will match. If commercial pricing is competitive, the lump sum buys you the same income plus the freedom to pick the carrier, the payout structure, and how much to annuitize at all.
How insurers turn a premium into a payment — and why age and payout shape move the number so much — is covered in our guide to how annuity payments are calculated, and the payout-structure rankings show how the income options stack up.
Taxes: Don't Cash the Check
If you take the lump sum, take it as a direct rollover to an IRA. A rollover moves the full amount with no current tax and no mandatory withholding, and it keeps every future option open — including buying your own annuity later, a path explained in our guide to annuity and IRA rollovers.
Cashing the check instead stacks the entire lump sum into one year of ordinary income — often the largest taxable year of your life — with possible early-withdrawal penalties on top depending on your age. There is almost never a good reason to do it.
Who Should Lean Which Way
Lean toward keeping the pension annuity if:
- You're healthy with long-lived parents — a life-contingent payment rewards longevity, and you'd collect the reward.
- Your spouse depends on survivor income and the plan's joint and survivor terms are strong.
- Social Security is your only other guaranteed income and your essential expenses exceed it.
- You do not want to manage a large balance — or don't trust yourself, or a future version of yourself, to spend it slowly.
Lean toward the lump sum if:
- Your health or family history makes a long retirement unlikely — a life-only pension pays poorly to those who die early.
- Your benefit is large enough to exceed PBGC caps and you have doubts about the plan's funding.
- You already have enough guaranteed income to cover essentials, so this money's job is growth and legacy.
- The market test above shows commercial annuity pricing matching or beating your pension's check.
The Middle Path: Take the Lump Sum, Build Your Own Pension
The choice is not all-or-nothing. Rolling the lump sum to an IRA and annuitizing part of it yourself splits the difference: you pick a financially strong carrier, choose the payout shape from the full payout options menu — including a joint and survivor annuity for a spouse — and keep the rest invested and accessible.
How much of the rolled-over money should become guaranteed income is its own decision, and the income-gap method in our guide to sizing an annuity allocation walks through it. If part of the plan is delaying Social Security, a bridge annuity can cover the gap years too.
Next Step: Run the Market Test Before You Sign
Buyout windows have deadlines, and the default is usually irrevocable either way. Before the deadline, put a real number on both sides: the pension's monthly check versus what the lump sum buys at current SPIA pricing. If the numbers are close, the softer factors — health, spouse, legacy, discipline — should break the tie.
