Pension Survivor Benefit Calculator

When you elect a pension survivor benefit, you're deciding how much income keeps flowing to a loved one after you're gone, and the choice between 0%, 50%, 75%, or 100% reshapes your own monthly check in the process. In 2026, with cost-of-living adjustments tied to inflation, the gap between these options can add up to thousands of dollars in lifetime income for a surviving spouse, which is why the election deserves careful thought before it's locked in.

The engine here is the reduction factor that gets applied to your single-life annuity. That factor depends on the survivor percentage you select, the age gap between you and your beneficiary, and the actuarial tables your pension plan is required to use. In practice the calculation takes your unreduced pension and multiplies it by a factor drawn from mortality probabilities, for example 0.9 for a 50% survivor benefit when there's a 5-year age difference between the two of you.

The trade-off is direct: the more protection you build in for your beneficiary, the smaller your own payment becomes while you're alive. Where people tend to miscalculate is in how much a surviving spouse will actually need, particularly as healthcare and long-term care costs climb later in retirement. Weigh those needs against your survivor's other income too, including Social Security, where the projected average for a retired worker in 2026 is $2,050/month.
