How Much Is My Pension Worth? How to Value a Lifetime Benefit

You cannot value a pension by adding up the checks, because a dollar received in 2050 is worth less than a dollar today. The correct measure is present value: what a lump of money today, invested at a reasonable rate, would need to be to reproduce all those future checks. Three inputs drive it:

Input	Effect on value
Monthly benefit	Higher benefit, higher value, proportionally.
Life expectancy	More years of payments, higher value. This is where your health matters.
Discount rate	Higher assumed return, lower present value (future checks are “cheaper” to fund today).

Your buyout offer is a present-value calculation too, but done under IRS Section 417(e) rules that tend to be conservative for a healthy person. Two reasons the offer often trails the true value of your checks:

• It uses average mortality. If you expect to live longer than average, the calculation undervalues your annuity, because it assumes fewer years of payments than you will likely collect.
• It uses prevailing interest rates. When rates are high, the same benefit converts to a smaller lump sum. See how lump sums are calculated.

This is not the plan cheating; it is the formula. But it means a healthy, long-lived person is frequently offered less than their pension is genuinely worth to them.

You do not need to compute present values by hand. The most useful single number is the hurdle rate: the annual return your lump sum would have to earn to reproduce your checks for life. Our calculator computes it from your monthly benefit, age, and offer.

• Low hurdle rate (bond-like or below): the lump sum roughly matches the pension's value, so it is a fair-to-generous offer.
• High hurdle rate (stock-market levels): the pension is worth clearly more than the lump sum for anyone expecting a normal or long life.

Present value understates a pension in ways worth naming:

• Longevity insurance. The pension cannot be outlived. A lump sum can.
• No management required. The check arrives whether or not you or a surviving spouse can manage money.
• Behavioral protection. It cannot be spent early in a lump, lent to relatives, or lost to a bad decision.
• Survivor options. A joint-and-survivor election protects a spouse for life.

None of these show up in a present-value number, and all of them are reasons a pension can be worth more to you than its calculated value, or the lump sum offered for it.
