The reduction is an estimate from a unisex mortality curve (life expectancy about 20 years at 65) and 5% interest; your plan uses its own tables, and its election packet shows the exact amounts. Break-even ignores interest: it is the point where the survivor has collected as much as your pension was reduced.

How It Works

A pension survivor option decides whether your pension keeps paying your spouse after you die, and how much of your own check you give up for it. Private-sector plans pay either a single-life annuity or a joint-and-survivor annuity that continues 50%, 75% or 100% to your spouse; federal FERS retirees choose a full (50%) or partial (25%) survivor annuity, or none. The election is generally locked in once payments start, so it is worth seeing both sides of the trade before you sign.

The two systems price the option differently. In a private plan, IRC §417 and ERISA §205 require the joint-and-survivor annuity to be the actuarial equivalent of the single-life annuity, and the survivor receives a percentage of that reduced joint payment. The calculator estimates the reduction from both ages with a unisex mortality curve (life expectancy about 20 years at 65) and 5% interest: for a retiree of 65 with a spouse of 60, the 50% option keeps about 89% of the single-life amount and the 100% option about 81%. Under FERS the cost is fixed by law whatever your ages, 10% of the annuity for the full benefit and 5% for the partial one, and the survivor's 50% or 25% is figured on the unreduced annuity (5 U.S.C. §8419 and §8442).

The break-even sets the two sides against each other without interest: if you live to your life expectancy, how many years must your spouse outlive you to collect back what the reductions cost? The answer does not depend on the percentage you pick, because a larger survivor benefit costs proportionally more, so the choice is about how much income to guarantee rather than which option is the better deal. Compare it with the calculator's odds that your spouse outlives you, and by how long. Weigh your survivor's other income too, including Social Security, where the average for a retired worker in January 2026 was $2,071/month, and check the exact figures in your plan's election packet, which uses its own tables.

Example: 75% Survivor Option on a $4,000 Pension

  1. 1 You are 65 and retiring from a private-sector plan with a single-life annuity of $4,000 a month. Your spouse is 60, and you are weighing the 75% joint-and-survivor option.
  2. 2 For those ages the calculator's estimated reduction is 15.01%: your pension becomes $3,399.41 a month, $600.59 less than the single-life amount.
  3. 3 After your death your spouse receives 75% of that reduced payment, about $2,550 a month. For comparison, under FERS the full survivor option would cost a flat 10%, leaving you $3,600, and pay your spouse 50% of the unreduced $4,000, or $2,000.
  4. 4 Break-even: if you live to your life expectancy of about 85 (20.1 more years), the reductions add up to $600.59 × 12 × 20.1 ≈ $144,900. At $2,550 a month ($30,600 a year) your spouse recovers that in about 4.7 years. The calculator puts the chance that a 60-year-old spouse outlives a 65-year-old at 62%, and those who do outlive their partner by about 12.5 years on average, well past the 4.7-year break-even.

Frequently Asked Questions

What are pension survivor benefit options?
Private-sector defined benefit plans must offer married retirees a joint-and-survivor annuity that pays the spouse 50% to 100% of the retiree's reduced payment, plus an optional alternative of 75% or 50%; taking a single-life annuity instead requires the spouse's written consent. FERS retirees choose a full survivor annuity (50% of the unreduced annuity, costing 10%), a partial one (25%, costing 5%) or none, and anything less than full also needs the spouse's consent. The higher the survivor percentage, the lower the payment while the retiree is alive.
Should I choose 100% or 50% survivor benefit on my pension?
It depends on how much income your spouse would need without you. In a private plan the cost grows with the survivor percentage and with how much younger your spouse is: in this calculator's model, with both of you at 65, the 50% option costs about 8% of the pension and the 100% option about 15%; with a 60-year-old spouse, about 10.5% and 19%. Because the pricing is actuarial, the break-even is the same for both, so the real question is how much income to guarantee. Compare the extra reduction with the cost of life insurance that would replace the same income.
What happens to my pension if I choose single life and die early?
With the single-life option, pension payments stop entirely when you die. Your spouse receives nothing from the pension. This option maximizes your monthly income but leaves your surviving spouse unprotected unless you have other income sources or life insurance.
