How to use
- 01
Enter the monthly pension your plan quotes on the single-life option — the largest figure on the election form, and the one that stops the day you do.
- 02
Check the 50% joint-and-survivor factor. It opens at 90%, which is PBGC's own published 2026 factor; your plan's election packet carries yours and it will differ.
- 03
Enter your plan's 75% and 100% factors from the same packet, or leave either at 0 and the page scales it from the 50% factor in proportion to the survivor percentage.
- 04
Enter both ages and the ages you are each planning to. The break-even is the whole decision, and it cannot be computed without all four.
- 05
Read the table: four elections, what each pays you, what each costs you, what each leaves your spouse, and how long they must outlive you before it pays for itself.
Formula
Your monthly benefit = the single-life amount × the plan's factor for that election. What it costs you = the single-life amount − that. Your spouse's check = your reduced benefit × the survivor percentage (50%, 75% or 100%). Break-even months = (what it costs you each month × the months you expect to collect) ÷ your spouse's monthly check. Where a 75% or 100% factor is left blank, it is scaled from the 50% factor: 1 − (the 50% election's cost share × the ratio of the survivor percentages).
Example
A $4,200 single-life pension at factors of 90%, 85% and 80% pays $3,780, $3,570 or $3,360 a month — costing $420, $630 or $840 — and leaves a spouse $1,890, $2,678 or $3,360. Retiring at 65 and planning to 84, you expect 228 monthly payments, so the 50% election costs $95,760 in all. Your spouse must outlive you by 4 years and 3 months for that to come back; on a spouse aged 62 planning to 89 they outlive you by 8 years. Discounted at 4%, the protection is worth about $5,600 more than it costs.
Definitions
- QJSA
- Qualified joint and survivor annuity — the default form of payment for a married participant, paying a survivor annuity of not less than 50% and not more than 100% of the joint-lives amount.
- Joint-and-survivor factor
- The share of the single-life benefit your plan pays under a survivor election, set from the plan's own interest and mortality basis and moving with the gap between your ages.
- Pop-up provision
- A plan feature restoring the full single-life benefit if your spouse dies before you. Not universal, rarely volunteered, and worth asking about before signing.
Good to know
The one election you make once and never again
Somewhere in the retirement paperwork is a page with four or five monthly figures on it: single life, and 50%, 75% or 100% joint-and-survivor. Choose one, sign, and the decision is essentially permanent from the annuity starting date. A divorce will not usually undo it. A remarriage will not usually undo it. Your spouse dying before you will not usually undo it either, unless the plan has a pop-up provision — a feature that restores the full single-life benefit if the spouse predeceases you, which some plans have, which changes the arithmetic on the calculator above completely, and which is almost never mentioned unless you ask for it by name. It is a six-figure decision made once, under time pressure, by people who have never made one before, and it is actively marketed to by an insurance industry with a product to sell against it.
Your spouse has a signature on this too
The Retirement Equity Act of 1984 wrote into the tax code and ERISA a rule most participants discover at the paperwork stage: a married participant's default form of payment is a qualified joint and survivor annuity, with a survivor annuity of not less than 50% and not more than 100% of the joint-lives amount. Electing anything else — single life, a lower survivor percentage, or a lump sum — requires the spouse's written consent, acknowledging the effect of the election, and witnessed by a plan representative or a notary public. A signature at the kitchen table does not count. A parallel qualified preretirement survivor annuity covers death before payments begin and is waived the same way. The 2006 Pension Protection Act added one more piece of structure that explains why the same two options keep appearing: if the plan's default survivor percentage is under 75% it must also offer a 75% option, and if it is 75% or more it must also offer a 50% one. That is why 50% and 75% sit on nearly every election form in the country.
The break-even, and why it is the argument rather than the answer
The arithmetic is straightforward. The election costs you a fixed amount every month for as long as you live, and pays your spouse a fixed amount every month afterwards. Divide the total cost by the monthly survivor benefit and you have the number of months your spouse must outlive you before the trade comes out even — about 4 years and 3 months on the 50% election priced above, and 4 years and 9 months on the 100% one. They break even at almost the same point, because cost and benefit scale together, which means the choice between 50% and 100% is not really an arithmetic question at all. It is a question about what your spouse would need. If the pension is most of the household income and their own Social Security is small, 75% or 100% is the honest answer. And note what the break-even is measuring: the case where the election loses is the case where your spouse dies soon after you, which is not the risk anyone is insuring against. The election exists for the case where they live another twenty years, and that is exactly the case a break-even calculation makes look expensive.
Pension maximization, and the four ways it goes wrong
Every insurance agent who works this market will propose the same alternative: take the larger single-life benefit, and spend part of the difference on a term life policy for your spouse. Sometimes it genuinely is cheaper — a healthy 60-year-old in good health can often buy meaningful coverage for less than a 100% survivor election costs. Four things have to hold for it to work, and all four fail quietly. Term insurance ends on a date and a pension does not, so a policy bought at 62 for twenty years leaves an 82-year-old widow with nothing. The premium is level only for the term; renewal pricing at older ages is brutal. Replacing the policy later requires you to still be insurable, and the whole point of the arrangement is that it must survive a decline in your health. And a death benefit arrives as a lump sum your spouse has to invest and manage, at the worst possible moment, rather than as a check that turns up every month for life. There is a fifth, specific to public-sector plans and easy to miss: retiree health coverage is frequently tied to the pension election, and a surviving spouse who is not receiving a survivor annuity can lose the health plan with it. Finally, the household loses the smaller of the two Social Security checks at the first death, so the income gap the election has to cover is always larger than the pension line alone.
Frequently asked questions
What does the survivor option actually cost?
A permanent reduction in your own monthly check, set by your plan's actuarial factors. On the figures here a $4,200 single-life pension becomes $3,780 under a 50% election — $420 a month, or $95,760 over the 19 years you expect to collect — and leaves your spouse $1,890 a month for the rest of their life. A 100% election costs $840 a month and leaves them $3,360.
Can I just take the single-life option?
Not on your own signature. Since the Retirement Equity Act of 1984 the default form of payment for a married participant is a qualified joint and survivor annuity, and electing anything else — single life, a lower survivor percentage or a lump sum — requires your spouse's written consent acknowledging the effect of the election, witnessed by a plan representative or a notary public.
How long does my spouse have to outlive me for this to pay?
On the 50% election here, about 4 years and 3 months. The arithmetic is the total you give up while alive, divided by what your spouse collects each month afterwards: $420 × 228 months, divided by $1,890. On the ages entered your spouse outlives you by 8 years, so the election clears — but the case it exists for is the one where they live much longer than that.
Is 50% or 100% the better election?
They break even at almost the same point — 4.2 years for the 50% election against 4.75 years for the 100% one, on these factors — because both the cost and the benefit scale together. The real question is what your spouse would actually need. If the pension is most of the household income and their own Social Security is small, 75% or 100% is the honest answer; if they have a pension of their own, 50% may be plenty.
What is pension maximization?
Take the single-life benefit and spend part of the difference on a term life policy for your spouse. It can work, and the four ways it fails are all real: term insurance ends on a date while a pension does not, the premium is only level for the term, a replacement policy requires you to still be insurable, and a death benefit is a lump sum your spouse has to invest rather than a check that arrives every month for life. In many public plans retiree health coverage is also tied to the survivor election.
Can I change my mind later?
Essentially never, after the annuity starting date. A divorce, a remarriage, or your spouse dying before you will not usually restore the single-life amount. Ask one question before you sign: does the plan have a pop-up provision that restores the full benefit if your spouse predeceases you? Some do, it changes this arithmetic completely, and it is rarely mentioned unless you ask.
