Pension vs. Lump Sum for a Long Life
Your employer offers $3,200/month for life or a $580,000 lump sum. If you expect to live to 90, which choice puts more money in your pocket?
This scenario covers
Core MathBreak-Even & Investment Return
Start with the simplest anchor. $580,000 ÷ $38,400 ≈ 15 years — so by about age 77the pension checks have repaid the original lump-sum amount in nominal dollars. But that ignores what the $580,000 could earn. The real question: if you take the lump sum, invest it, and draw the same $38,400/year, how long does it last?
Modeled as $580,000 invested from age 62 at a fixed annual return, with $38,400 withdrawn at each year-end (matching the pension income, no inflation adjustment):
| Lump-sum return | Lump-sum path outcome | What it means |
|---|---|---|
| 3% (conservative) | Runs out ~age 82–83 | Past your early-to-mid 80s, the pension's guaranteed income pulls ahead |
| 5% (balanced) | ~$31,000 left at 90; depletes ~age 91 | Roughly a wash at 90 — and until then the lump-sum path funds the same income and keeps a balance |
| 7% (equity-heavy) | ~$758,000 left at 90 | Under this deterministic return the lump sum stays far ahead |
Deterministic returns; ignores taxes, inflation, and sequence-of-returns risk. Cumulative pension to age 90 with no cost-of-living adjustment = 28 × $38,400 = $1,075,200.
Survivor BenefitsJoint & Survivor vs. Single Life Options
Most pensions offer a "joint and survivor" (J&S) option that continues payments to a surviving spouse, but at a reduced rate. Choosing J&S reduces the monthly payment but protects the surviving spouse.
| Pension option | Monthly payment | What happens at your death |
|---|---|---|
| Single Life Only | $3,200/mo | Payments stop immediately |
| J&S 100% (full survivor) | $2,400/mo (25% reduction) | Spouse receives $2,400/mo for life |
| J&S 50% (half survivor) | $2,720/mo (15% reduction) | Spouse receives $1,360/mo for life |
RiskEvaluating Your Pension Fund's Health
A pension is only as good as the plan funding it. Before choosing the pension over the lump sum, verify the plan's financial health — especially for private-sector pensions.
- PBGC protection: The Pension Benefit Guaranty Corporation insures private-sector DB plans up to $7,789.77/month (2026, age 65 single). If your pension is within this limit, it's effectively guaranteed.
- Government/municipal pensions: Not covered by PBGC. Review your state's pension funded ratio (below 70% is a concern).
- Private-sector underfunded plan: If the plan's funded ratio is below 80% and not improving, the lump sum may be the safer choice — you eliminate credit risk.
- Where to check: Your annual pension statement, PBGC.gov for PBGC-covered plans, and your state auditor's website for public pension data.
Verdict: Which Should You Choose?
There is no single answer. At conservative returns (~3%) the invested lump sum runs dry in the early 80s, so a long life tilts strongly toward the pension's guaranteed income. Around 5% the lump-sum path lasts to about age 90–91 — roughly even — while still leaving a balance along the way. At sustained higher returns (~7%) the lump sum stays well ahead. So the choice turns on how long you expect to live, what return you can realistically sustain, your tolerance for sequence-of-returns risk, and whether leaving an estate matters. To eliminate longevity and investment risk with limited appetite for managing a portfolio, take the pension; with other guaranteed income, strong investing discipline, or estate goals, the lump sum has a real case.
