- Divide the annual pension by the lump sum to get the payout rate the pension is offering. That single number frames the entire decision.
- The pension's implied rate is usually compared against what an insurer would charge for the same income — get a real SPIA quote before deciding.
- The survivor election is a separate and often larger decision than lump sum versus annuity, and it is usually irrevocable.
- Pension payments are backstopped by the PBGC up to a limit; a lump sum rolled to an IRA has no such backstop but no carrier risk either.
- Lump sum offers carry short deadlines, and the offer amount moves with interest rates — a rising-rate year shrinks lump sums.
An employer hands you two numbers and a deadline. Almost every article about this decision talks about temperament — do you want certainty, do you trust yourself with a large sum. Those matter, but they come second. First there is a calculation, and it takes ten minutes.
Start with the payout rate
Divide the annual pension by the lump sum offered. That percentage is the payout rate the pension is giving you.
A $30,000 annual pension against a $500,000 lump sum is a 6% payout rate. A $30,000 pension against a $700,000 lump sum is 4.3%. Same pension, very different offers — and the single number tells you which.
Now benchmark it. Get a real quote from an insurer for the same lifetime income, at your age, with the same survivor structure. Our SPIA guide explains why only a quote answers this and why quotes differ several percent between carriers in the same week.
If the pension's rate beats the market rate, the pension is giving you more income per dollar than you could buy. Taking the lump sum means accepting less income and taking on the job of managing it. That is a steep hill.
If the market rate beats the pension's, the lump sum is genuinely worth considering — you could buy more income than the pension offers and keep the difference, or invest it and accept the risk.
The second calculation: present value
The payout-rate method compares income efficiency. The present-value method asks what the promised stream is worth today.
Discount the pension's payments at a rate you could honestly earn with comparable safety — our present value guide has the full factor table. A $30,000 pension for 25 years discounted at 5% has a present value of roughly $423,000; the same stream at 4% is about $469,000.
Compare that to the offer. A lump sum well below the present value is asking you to accept a high discount rate on money that is already yours. Sometimes that is still the right call — but it should be a visible choice rather than an invisible one.
The survivor election, which is the bigger decision
If you take the pension, you elect a survivor option, and for a married person this is frequently worth more than the lump-sum question.
Single life pays the most and stops at your death. A surviving spouse gets nothing. Joint and survivor pays less monthly and continues at 50%, 75%, or 100% to the survivor.
The gap between single life and 100% joint-and-survivor is the price of insuring your spouse's income, and it is usually cheaper than buying that protection any other way. Two things make this decision heavy: it is generally irrevocable, and spousal consent is typically required to waive it — a legal safeguard worth understanding rather than signing past.
The interaction with a lump sum is direct: a lump sum rolled to an IRA passes to your beneficiaries in full, which is the one place the lump sum clearly beats a single-life pension. Compare like with like — lump sum against the joint-and-survivor pension, not the headline single-life number.
Who stands behind each option
The pension is backed by your employer's plan and insured by the Pension Benefit Guaranty Corporation up to statutory limits for private plans. Government and church plans are generally outside PBGC coverage.
The lump sum, rolled to an IRA, has no insurance at all — and no carrier risk either. It is your money in your account, subject to your investment results.
One development belongs in this decision because it can happen without your consent: in a pension risk transfer, your employer pays an insurer to assume the obligation. Your checks continue identically, but PBGC coverage ends and state guaranty coverage replaces it. If your employer has signalled a transfer, the "safety" comparison you are making today may not describe next year.
Where each side genuinely wins
The pension wins when the payout rate beats what insurers charge, when you value not managing money, when longevity runs in your family, and when a joint-and-survivor election protects a spouse who would otherwise be exposed. It also wins on discipline: the money cannot be spent early because it does not exist as a sum.
The lump sum wins when the payout rate is poor, when you have health that makes a long payout unlikely, when leaving assets to heirs matters more than maximum income, when you have other guaranteed income covering essentials already, and when you genuinely have the infrastructure to manage it.
There is also a middle route almost nobody is offered: take the lump sum and annuitize part of it. Roll to an IRA, buy income covering the gap your income floor actually needs, invest the rest. You get the guarantee where it matters and keep the flexibility elsewhere — often at a better payout rate than the pension offered, because you can shop carriers and the pension is a single quote.
Before the deadline
Compute the payout rate. Get two real SPIA quotes for the same income and survivor structure. Compare the lump sum to the present value at an honest discount rate. Price the survivor election separately, because it is a separate decision. Confirm whether a rollover is direct — taking receipt of a lump sum personally can trigger mandatory withholding and a tax bill you did not intend.
All of that fits in a week. The offer letter will suggest you have less time than you do; the underlying decision is permanent and deserves the week.
