Pension Buyout Calculator: Is Your Offer Fair?

Why companies offer pension buyouts

Corporate pension obligations sit on the balance sheet as liabilities. A company with a $500 million pension obligation carries that number as debt, which affects credit ratings, borrowing costs, and what acquiring companies will pay in a deal. Getting retirees and near-retirees to accept lump sums converts those long-term uncertain liabilities into a single knowable expense. The accounting motivation is strong.

The offers tend to come in waves. After the 2012 IRS changes to lump sum calculation methods, dozens of Fortune 500 companies ran large buyout programs. Ford, General Motors, Motorola, Sears: each offered buyouts to tens of thousands of retirees and vested former employees. The pattern repeats when interest rates shift, because the discount rate used to calculate lump sum values moves with the IRS 417(e) segment rates. When rates rise, lump sum values fall. Many of the offers seen in 2025 and 2026 reflect employers moving before rates fall again.

That timing matters for you. The calculator above values your pension with the same 417(e) segment rates and IRS mortality table a plan uses, discounted from your age today. That tells you whether the offer matches the plan's own yardstick. It then runs the test that's about you: invest the offer at your own assumed return, pay yourself the pension's income, and see how long the money lasts.

How to evaluate the offer

The central question is whether you can earn more from the lump sum than the pension is implicitly promising you. The pension's implied return is the discount rate that makes the present value of all future payments exactly equal to the lump sum offer. That rate is your break-even hurdle.

A no-COLA private pension for a 60-year-old with a life expectancy of 85 typically implies a return rate of 4-6%. If you believe you can consistently earn more than that from an invested lump sum (after fees, taxes, and the inevitable market volatility), the math favors the buyout. The lump sum vs. annuity calculator shows the implied IRR and break-even year for any pension offer. If you can't, or won't, the pension wins.

Three inputs shift this analysis more than anything else. First, life expectancy. Every year you live past the age the invested buyout runs out is a year only the pension pays. The pension has no ceiling. The lump sum, spent at 4% per year, depletes. Second, COLA. A pension with a 2-3% annual cost-of-living adjustment is a fundamentally different product than a fixed payment. Its implied return is 2-3 percentage points higher, and the hurdle for the lump sum rises accordingly. Third, your actual investment behavior. The analysis assumes you roll the lump sum to an IRA and invest it at the assumed return, undisturbed, for decades. Reality adds panic selling, early withdrawals, advisor fees, and sequence-of-returns risk in the first few retirement years when a bear market does the most damage.

What to watch for in the offer letter

Before running any numbers, verify four things in the offer document.

The payment start date. Some offers are for deferred vested employees who aren't yet collecting. Others go to current retirees already receiving checks. The present value calculation is completely different for each. If you're 55 and your pension wouldn't start until 65, the 10-year deferral period significantly reduces the lump sum's comparative value, because you can invest the buyout during those same years.

The survivor election that's embedded in the offer. Many buyout calculations are based on the single-life annuity amount. If you planned to elect a joint-and-survivor option to protect a spouse, the true pension alternative is the lower joint-survivor monthly amount, not the single-life figure. Using the single-life number in the comparison overstates how good the pension is relative to the lump sum.

The COLA provision. Check your plan document, not the offer letter. Offer letters often quote the monthly benefit without mentioning whether it adjusts for inflation. Plans sometimes have COLA provisions that only trigger under certain conditions, or that apply only to the first portion of the benefit. This matters enormously for a 25-year retirement.

The deadline and the rollover instructions. Most offers require a decision within 30-90 days. The direct rollover procedure is critical: if the plan sends you a check instead of wiring funds directly to your IRA custodian, the plan must withhold 20% for federal taxes, and you have 60 days to deposit the full amount (including the withheld 20% from other funds) to avoid taxes and penalties. Always request a direct trustee-to-trustee transfer.

Inflation and what no-COLA means over time

Most private-sector pension buyout offers involve benefits with no COLA. That looks fine at age 62. At age 82, after 20 years of 3% inflation, a $2,000 monthly pension has the purchasing power of about $1,107 in today's dollars. You're technically still receiving $2,000, but it buys roughly half what it did when you retired. The lump sum, invested and withdrawn at 4%, can potentially grow to partially offset inflation, though that depends on actual market returns.

This is one of the honest arguments for taking the buyout even when the present value calculation favors the pension: a growing portfolio provides inflation protection that a fixed payment doesn't. The counterargument is that Social Security has a COLA, so if you're combining Social Security with the pension, the fixed pension may be less damaging than it looks in isolation.

PBGC coverage and employer risk

The Pension Benefit Guaranty Corporation insures most private-sector defined benefit plans. If your employer's plan fails, the PBGC takes over payments, up to a cap. For plans terminating in 2026, the PBGC maximum guarantee for a 65-year-old retiree is roughly $7,790 per month ($93,477 per year). Benefits above that cap are at risk in an employer insolvency. Check pbgc.gov for the exact current-year limit.

If your monthly pension is well under that ceiling and your employer is financially stable, PBGC risk is a minor concern. If you work for a company in a distressed industry, the plan is significantly underfunded (you can check the funding percentage in the annual funding notice your plan must send you), or your benefit exceeds the PBGC cap, the buyout removes that credit risk entirely. A lump sum rolled to an IRA is SIPC-protected up to $500,000 and not subject to any employer insolvency.

Investment risk and the 4% rule

The comparison above assumes the lump sum generates income at a 4% annual withdrawal rate, the commonly referenced "safe withdrawal rate" from the 1994 Bengen study and the subsequent Trinity Study. At 4%, a $350,000 buyout generates $1,167 per month. That rate was derived from historical U.S. equity and bond returns over 30-year retirement periods. It survived every historical 30-year period starting from 1926.

What it didn't survive: 40-year retirements, portfolios tilted toward bonds in a low-rate environment, or investors who panic-sell during the first decade of retirement. If you retire at 60 and live to 95, you need 35 years of portfolio longevity. At that horizon, 3.5% or even 3% may be the more honest withdrawal assumption. That changes the monthly income comparison significantly, and often tips the balance back toward the pension for anyone with reasonable longevity.
