Pension: Lump Sum vs Annuity
Compare a pension lump sum payout against lifetime monthly annuity payments to determine which option is more valuable.
Enter Your Details
When the Lump Sum Wins
- Below-average health — family history, smoking, chronic conditions reduce expected lifespan
- You want to leave an inheritance — annuities die with you (or your spouse, if joint)
- You distrust the pension's solvency — multi-employer plans, weak company finances
- You have disciplined investment skills — can earn 6-7%+ over 20+ years
The PBGC backstop is limited: $7,107.95/mo max guarantee for age-65 single-employer plans in 2026, far less for multi-employer plans.
When the Annuity Wins
- Above-average longevity — good health, family history of 85+, female (avg 19.7 yr life exp at 65)
- You lack investment discipline — would spend the lump sum or panic-sell in downturns
- You need predictable income — fixed expenses, no other guaranteed income besides Social Security
- Pension is from a strong employer — government, federal, financially stable corporate plan
Mortality credits: annuity pools effectively pay healthy 65-year-olds an extra ~1-3% per year of return — impossible to replicate with self-managed investments.

Breakeven Age — At What Age Does Lifetime Annuity Beat Lump Sum?
The simplest framing: how many years of monthly pension payments equal the lump sum offer? Breakeven age = retirement age + (lump sum / annual pension). If you live past breakeven, the annuity wins. If you die before, the lump sum wins (your heirs do, anyway).
| Scenario | Lump Sum | Pension/Year | Simple Breakeven | SSA Life Expectancy at 65 |
|---|---|---|---|---|
| Modest lump (15-yr breakeven) | $300,000 | $20,000 | 15 years (age 80) | 65M=82, 65F=85 — annuity wins |
| Typical case (18-yr breakeven) | $500,000 | $28,000 | ~18 years (age 83) | 65M=82, 65F=85 — coin flip |
| Generous lump (12-yr breakeven) | $400,000 | $33,000 | 12 years (age 77) | 65M=82, 65F=85 — annuity wins big |
| Stingy annuity (25-yr breakeven) | $500,000 | $20,000 | 25 years (age 90) | 65M=82, 65F=85 — lump sum wins |
SSA 2022 life expectancy (latest available)
| Current Age | Male: Expected Years Remaining | Female: Expected Years Remaining | 50% Survive To |
|---|---|---|---|
| 55 | 25.4 (age 80) | 28.7 (age 84) | ~age 80-84 |
| 60 | 21.0 (age 81) | 24.0 (age 84) | ~age 81-84 |
| 65 | 17.0 (age 82) | 19.7 (age 85) | ~age 82-85 |
| 70 | 13.6 (age 84) | 15.9 (age 86) | ~age 84-86 |
| 75 | 10.5 (age 85) | 12.4 (age 87) | ~age 85-87 |
For a married couple at 65: there's a 50% probability that at least one spouse lives to 92+. This is why Joint & Survivor elections — even with their lower monthly payments — often deliver more total lifetime income than single-life options for couples.

Mortality Credits — Why You CAN'T Match An Annuity With Investing
An insurance company pools thousands of annuitants. Those who die earlier than expected effectively subsidize those who live longer. This is "mortality credits" — and it's mathematically impossible for a single self-managed retiree to match it. The mortality credit alone adds ~1-3% per year of effective return for healthy 65-year-olds.
| Investment Approach | Annual "Yield" From $500K at age 65 | Lasts How Long? | Catches Mortality Credits? |
|---|---|---|---|
| 4% rule (Bengen) self-managed | $20,000 (4% of $500K) | 30 years (95% confidence) | NO |
| 3% conservative draw | $15,000 | 40+ years | NO |
| SPIA (life-only, 65M, 2026 rates) | $37,500/yr ($3,125/mo) | For life — could be 30+ years | YES — 7.5% annual rate possible |
| SPIA (life-only, 65F, 2026 rates) | $35,400/yr | For life | YES — 7.08% annual rate |
| SPIA Joint 65/65, life-only | $31,800/yr | For life of last surviving spouse | YES — survives both |
- Invests your premium in conservative bonds (yields ~5% in 2026)
- Pays out interest + portion of principal
- Keeps any remaining principal when you die (in life-only options)
- Pools risk across thousands — those who die early subsidize those who live
When self-managed CAN beat the annuity
- Long bull market with high stock returns. 8-10% portfolio growth can outpace mortality credits, especially over 25+ years.
- You die earlier than expected. Self-managed wealth passes to heirs; annuity (life-only) does not.
- You have the discipline to NOT overspend the lump sum. Behavioral risk is the #1 reason self-managers fail.
- You have other guaranteed income (Social Security, second pension, spouse's pension) — so you don't NEED the longevity protection.
Mortality credit analysis per Wade Pfau "Annuities and Retirement Research." Bengen 4% rule from 1994 paper. Modern SAFEMAX research from Morningstar finds ~3.7% safe withdrawal rate for 30-year horizon.
IRS §417(e) — How Pension Plans Calculate Your Lump Sum
Pension plans must use IRS-prescribed mortality tables and discount rates to calculate lump-sum offers under IRC §417(e). The discount rate is based on segmented Treasury yields, updated monthly. Higher rates = LOWER lump-sum offers (because $1 today is worth less if rates are high).
| Discount Rate Environment | Effect on Lump Sum Offer | Better Choice |
|---|---|---|
| Low rates (2020-2022, ~2%) | Lump sums ~30-40% HIGHER than typical | Lump sum often advantageous |
| 2026 elevated rates (~4-5%) | Lump sums ~25-35% LOWER than 2021 peak | Lifetime annuity often better — verify carefully |
| Very high rates (1980s, ~10%) | Lump sums very low | Lifetime annuity dominant |
Verify the math yourself
Calculate the present value of the offered annuity using a reasonable discount rate (e.g., 4.5% Treasury 10-year as of 2026). Use the IRS 2026 mortality table (current applicable mortality for §417(e)). If the lump sum is significantly LOWER than your computed PV (>10% gap), the plan is offering you a bad trade. This often happens when plans use higher discount rates than market suggests, or older mortality tables that underestimate longevity.
Lump sums of $5,000 or less
If your accrued benefit's present value is ≤ $7,000 (effective 2025+ per SECURE 2.0 §304), the plan can force you to take a lump sum without your consent. Below $1,000, it's automatic without IRA rollover required. The change from $5,000 to $7,000 affects more workers — small balances now treated as automatic cashouts unless you proactively roll over to an IRA.
IRC §417(e) discount rate calculation methodology in IRS Notice 2025-XX (annual updates). Mortality table updates per IRS Reg §1.417(e)-1. Force-out threshold raised from $5,000 to $7,000 by SECURE 2.0 §304 effective 2025.
Investment Risk — Can You Outperform The Annuity?
If you take the lump sum and earn investment returns, can you beat the lifetime payments? Possibly — but you take on three categories of risk the annuity removes: sequence risk, longevity risk, and behavioral risk. Each can be large.
Sequence-of-returns risk ↘
If markets drop 30% in your first 2 years of retirement while you're withdrawing, you may run out of money 5-10 years earlier than projected. Bengen's 4% rule was designed to survive even the worst sequences (1968-1998).
Longevity risk ↗
A 65-year-old has ~25% chance of living past 90. If you self-manage planning for "average" 82-year life expectancy, you face material risk of outliving the money. Annuity removes this.
Behavioral risk ⚠
Studies of NFL players, lottery winners, and pension lump-sum recipients consistently show 30-70% spend the lump sum within 5 years. Discipline isn't easy when the money's all in one account.
| Lump Sum Approach | Expected Lifetime Income | Worst Case | Best Case |
|---|---|---|---|
| Conservative bonds (3% return) | ~Annuity-equivalent | Money lasts 25-30 years | Same as expected |
| 60/40 portfolio (5-7% expected) | 10-30% MORE than annuity | Sequence risk: lasts 20-25 years if bad | 50% MORE than annuity if good |
| 100% stocks (8-10% expected) | 40-80% MORE if survive sequence | Sequence risk: lasts 15-20 years if very bad | 2-3x annuity income if good |
| Spend lump sum (no return) | Less than annuity | Out of money in 10-15 years | Same as worst case |
Sequence risk research per Bengen 1994 + extensive subsequent literature. Behavioral data from Center for Retirement Research. Barbell strategy advocated by Bernicke, Pfau, Bogleheads.
Health-Based Decision — How Your Personal Mortality Affects The Math
Annuity payouts are based on AVERAGE life expectancy. If you have better-than-average health (good genetics, no smoking, active, fit), the annuity is a great deal because you'll likely outlive its actuarial assumptions. If you have worse-than-average health, the lump sum is better because you'll likely die before the breakeven point.
| Health / Genetic Factor | Effect on Decision |
|---|---|
| Family longevity (parents lived to 85+) | Lean toward annuity — you may live 90+ |
| Family early-mortality history (parents died <75) | Lean toward lump sum — annuity likely loses |
| Excellent personal health (BMI normal, active, no smoking) | Strong lean toward annuity |
| Major chronic illness (diabetes, heart disease, cancer) | Lean toward lump sum (or "impaired-risk" annuity) |
| Smoker (currently or recently) | Strong lean toward lump sum (10+ year lifespan reduction) |
| Female (3-year longevity advantage) | Lean toward annuity even more than males |
Decision framework — quick scorecard
- Take ANNUITY if 4+ true: good health • family longevity • need guaranteed income • not a confident investor • have spouse to protect • limited other savings
- Take LUMP SUM if 4+ true: chronic illness • family early-mortality • plenty of other guaranteed income • confident DIY investor • want legacy for heirs • plan financially distressed
- SPLIT (partial annuity) if mixed: Take lump sum, immediately buy SPIA covering essential expenses, invest rest. Best risk-adjusted approach for most retirees with 4-6 mixed factors.

Things to Know
Essential concepts for understanding your results
Key DifferencesHow do pensions and annuities compare?
Pension: employer-funded, guaranteed lifetime income based on years of service and salary, managed by employer/plan administrator. Annuity: self-funded via lump-sum or periodic payments to an insurance company, income based on contribution amount and contract terms. Pensions are disappearing (only 15% of private sector offers them); annuities are the private market alternative. Both provide guaranteed income but differ fundamentally in who funds and manages them.
Lump Sum vs AnnuityShould you take a pension lump sum or monthly payments?
Take monthly payments if: you expect to live past the break-even age (usually 80-82), you value guaranteed income, or you lack investment discipline. Take the lump sum if: you have health concerns suggesting shorter lifespan, you are a disciplined investor who can generate higher returns, you want to leave an inheritance, or you distrust the pension fund's long-term solvency. Run the break-even calculation: lump sum invested at expected return vs accumulated monthly payments.
COLA ProtectionHow does inflation affect pension and annuity income?
Most private pensions have no cost-of-living adjustment (COLA) — a $3,000/month pension today buys $1,800 worth of goods in 20 years at 3% inflation. Federal/military pensions have COLA tied to CPI. Annuities with inflation riders cost 10-25% more but maintain purchasing power. Without COLA, a $36,000/year pension effectively becomes $21,600 in real value after 20 years — barely supplemental income rather than the retirement foundation it started as.
Survivor BenefitsWhat happens to pension/annuity income when you die?
Pensions: single-life option pays more but stops at death. Joint-and-survivor option (typically 50-100% to spouse) pays 10-25% less monthly but protects your spouse. Always choose joint-and-survivor if your spouse depends on the income. Annuities: depends on contract — life-only stops at death, period-certain guarantees minimum years, joint-and-survivor continues for both lives. The wrong survivor election can leave a spouse financially devastated.
Pension vs Annuity: Understanding Guaranteed Retirement Income
Both pensions and annuities provide guaranteed periodic income, but they differ fundamentally in source, cost, and control. A pension is an employer-funded benefit earned through years of service. An annuity is a financial product you purchase from an insurance company. Understanding the differences — and when an annuity can replace a missing pension — is critical for retirement planning in an era when pensions are disappearing.
The pension crisis: In 1980, 38% of private-sector workers had a defined-benefit pension. By 2026, that number has dropped to approximately 15% — and virtually all new hires at private companies receive a 401(k) instead. Government employees (federal, state, military, teachers, police/fire) remain the primary pension recipients. The shift from pensions to 401(k)s transferred all investment risk and longevity risk from the employer to the employee — which is why retirement planning is more complex and more important than ever.
Bureau of Labor Statistics data shows that in 2024, only 15% of private industry workers had access to defined benefit plans, compared to 86% of state and local government workers. If you do not have a pension, an annuity is the primary tool to create pension-like guaranteed income in retirement.
How Pensions Work
A defined-benefit pension pays a guaranteed monthly amount for life, calculated using a formula based on years of service and salary. The typical formula: Years × Multiplier × Final Average Salary.
Example: A teacher with 30 years of service, a 2% multiplier, and a $70,000 final average salary: 30 × 0.02 × $70,000 = $42,000/year ($3,500/month) for life. This continues regardless of market conditions, how long you live, or what happens to the pension fund.
Federal employee pension (FERS): Uses a 1% multiplier (1.1% if retiring at 62+ with 20+ years). 30 years at $90,000 average salary: $27,000-$29,700/year. Combined with Social Security and TSP (the federal 401k equivalent), FERS provides a comprehensive retirement package.
Military pension: 2.0% multiplier × years of service × base pay. 20 years at $7,000/month base pay: $2,800/month for life starting immediately at retirement (which can be as early as age 38-42). Military pensions are among the most generous, with COLA adjustments and Tricare healthcare access.
Key pension decisions: Most pensions offer a choice between a higher single-life benefit (payments stop when you die) and a lower joint-and-survivor benefit (reduced payments continue to your spouse after your death). The survivor benefit is typically 50-75% of the full amount. If your spouse depends on this income, the survivor option is usually worth the reduction. If your spouse has substantial independent income or savings, the higher single-life payment plus a life insurance policy may produce more total income.
How Annuities Replace Pensions
If you do not have a pension, a Single Premium Immediate Annuity (SPIA) creates nearly identical guaranteed lifetime income:
Current SPIA payout rates (2026 approximate, per $100,000 premium):
Age 62: $560-$600/month. Age 65: $600-$660/month. Age 67: $640-$700/month. Age 70: $700-$780/month. Joint-life (same-age couple): 15-20% less per month than single-life.
To replicate a $3,500/month pension at age 65: you would need approximately $530,000-$580,000 in SPIA premium. This is a significant sum — but it provides the same guarantee as a pension: income that cannot be outlived, is not affected by market performance, and requires zero management.
The hybrid approach (most recommended): Do not annuitize your entire portfolio. Instead, calculate your essential expenses (housing, food, insurance, utilities, healthcare) minus guaranteed income (Social Security). The gap is your "income floor" need. Annuitize enough to cover this floor, and keep the rest invested for growth, flexibility, and legacy.
Example: Essential expenses $4,000/month. Social Security: $2,200/month. Gap: $1,800/month. Purchase a SPIA for approximately $270,000-$300,000 to cover the $1,800 gap. Keep remaining savings ($400,000+) invested in a diversified portfolio for discretionary spending, inflation protection, emergencies, and legacy.
Pension Lump Sum vs Monthly Payments
Some employers offer retirees a choice: take the pension as monthly payments for life or accept a one-time lump sum. This is one of the most consequential financial decisions a retiree makes.
Take the monthly pension if: You are in good health and expect to live past your mid-80s (the typical breakeven age). You want guaranteed income with zero management. You are not confident in your ability to invest a lump sum wisely. Your pension includes COLA adjustments (inflation protection). The pension's implicit return exceeds what you could earn investing the lump sum (typically 5-7% — compare the monthly payment to the lump sum).
Take the lump sum if: You are in poor health or have shortened life expectancy. You have significant investment expertise or a trusted financial advisor. You want to leave the remaining balance to heirs (pension payments stop at death or spouse's death). Your employer's pension fund is underfunded (risk of reduced benefits). You can roll the lump sum into an IRA for continued tax-deferred growth and flexible withdrawals.
The math: Divide the annual pension payment by the lump sum offer. If your pension pays $36,000/year and the lump sum is $500,000: the implicit return is 7.2%. If you believe you can consistently earn more than 7.2% investing the lump sum, take the lump sum. If not, the guaranteed 7.2% pension is the safer bet. Most people cannot consistently beat this rate after fees and taxes, making the monthly pension the better choice for the majority.
