Short answer
Pension lump sum vs annuity: which should you take?
Take the monthly pension when it pays more lifetime income than the lump sum could buy from an insurer, when it has a cost-of-living adjustment, when your spouse needs a survivor benefit, or when you are healthy and expect to live past your mid-80s. Take the lump sum when your health is poor, when there is no COLA and the pension’s implied return is below what you can lock in elsewhere, or when you want money left for heirs.
The simplest test: get an immediate annuity quote for the lump sum amount. If that quote beats the pension’s monthly check for the same survivor option, the lump sum wins on income alone. If you take the lump sum, roll it directly to an IRA so the plan does not withhold 20% for tax.
TL;DR: The pension lump-sum-vs-monthly decision depends on 7 factors: your health, your spouse, COLA, IRR breakeven, carrier risk (PBGC), taxes, and legacy goals. The 7-step scoring rubric below assigns 0-3 points per factor; total score above 14 favors lump sum, below 8 favors monthly, 8-14 needs deeper modeling. $500K and $1M sample math included. Most buyers without COLA-protected pensions and average health do better with a lump sum rolled into a MYGA ladder or SPIA, but only if they don't blow the lump sum.
The 7 factors in order of importance
- Health and life expectancy. If you're 65 with above-average health and family longevity, monthly pension wins the IRR race because you live long enough to collect. If you have a serious health condition, lump sum wins because monthly stops at death (unless joint-survivor).
- Spouse and survivor protection. A joint-and-survivor pension reduces monthly payment by 10-30% but continues to a surviving spouse. Single life pays more but stops at your death. Spousal need to continue income is decisive.
- COLA adjustments. Federal pensions and some union plans have COLA. Most private corporate pensions do not. A non-COLA monthly pension loses 30-50% real value over a 25-year retirement. That is a major argument for the lump sum.
- IRR breakeven age. Calculate what age the monthly payments equal the lump sum (without time value). Most buyers find IRR breakeven at age 78-85. Live past that, and monthly wins. Die before, and the lump sum wins.
- Carrier / plan risk. Private single-employer pensions are PBGC-backed up to $7,789.77/month at age 65 for a straight-life annuity (plans ending in 2026, PBGC). Public pensions (state, federal) have varying protections. Underfunded plans add risk to the monthly option.
- Tax treatment. Monthly is taxed as ordinary income in the year received. Lump sum rolled to IRA is tax-deferred. Lump sum taken as cash is fully taxable immediately. That is usually a disaster.
- Legacy / estate. Monthly stops at your death (or your spouse's). Lump sum in an IRA passes to heirs (subject to SECURE Act 10-year rule). If leaving assets matters, lump sum wins.

The scoring rubric (0-3 points each)
| Factor | 3 points | 2 points | 1 point | 0 points |
|---|---|---|---|---|
| Health/longevity | Serious condition; short life expectancy | Below average | Average | Above-average, long-lived family |
| Spouse | No spouse or independently wealthy | Spouse with own income | Spouse partially dependent | Spouse fully dependent on your income |
| COLA | No COLA on monthly | Partial / capped COLA | Full COLA capped at 2-3% | Full uncapped COLA |
| IRR breakeven | Past your life expectancy | 5+ yrs past life expectancy | Within 5 yrs of life expectancy | Before life expectancy |
| Plan risk | Underfunded; PBGC-cap binds | Marginal funding | Adequately funded | Federal / well-funded public |
| Tax flexibility | Need IRA rollover flexibility | Some tax planning benefit | Roughly equivalent | Lump sum forces tax problem |
| Legacy | Heirs matter; healthy estate plan | Some legacy goal | Mild legacy interest | No legacy goal |
Scoring: Total 14-21 points: lump sum likely wins. Total 8-13: needs deeper modeling. Total 0-7: monthly likely wins.
$500,000 sample math (age 65, no COLA, joint-survivor)
Employer offers either: $500,000 lump sum OR $2,850/month single life ($2,400/month joint 50% survivor) starting now.
| Option | Income year 1 | Income year 20 | Total paid by age 85 | Survivor benefit |
|---|---|---|---|---|
| Monthly single life | $34,200 | $34,200 (no COLA) | $684,000 | $0 |
| Monthly joint 50% | $28,800 | $28,800 | $576,000 (then $14,400/yr to spouse) | $14,400/yr to spouse |
| Lump sum → 5-yr MYGA at 5.95% → SPIA at 70 | $0 (deferring) | $35,400 | $420,000 (years 70-85) | Cash remainder (varies) |
| Lump sum → 70/30 portfolio, 4% withdrawal | $20,000 | ~$22,000 (inflation-adjusted) | ~$440,000 | Cash remainder (varies) |
| Lump sum → SPIA now | $36,000 (current 7.2%) | $36,000 (no COLA option) | $720,000 | $0 (period certain optional) |
Insights:
- An immediate SPIA on the lump sum often beats the employer's monthly offer by 5-10%, because insurance carriers have more efficient longevity pools than corporate pension plans
- The MYGA ladder + delayed SPIA approach allows flexibility and tax planning but produces less total cash income
- The 4% withdrawal approach exposes the buyer to sequence-of-returns risk
- The joint-50% monthly preserves $14,400/yr to spouse, which the single-life option does not
$1,000,000 sample math (age 62, COLA, single life)
Employer offers either: $1,000,000 lump sum OR $4,500/month single life with 2% COLA starting at 65.
| Option | Income year 1 (age 65) | Income year 20 (age 85) | Total paid age 65-85 |
|---|---|---|---|
| Monthly COLA pension | $54,000 | $80,250 (with 2% COLA) | $1,308,000 |
| Lump sum → 5-yr MYGA → SPIA at 67 | $0 (year 62-65), then $66,000/yr | $66,000 (no COLA option) | $1,254,000 |
| Lump sum → 70/30 portfolio, 4% withdrawal | $40,000 | ~$46,000 (inflation-adjusted) | ~$880,000 |
| Lump sum → immediate SPIA at 62 | $65,000 | $65,000 (no COLA) | $1,495,000 |
The COLA pension is a strong option here precisely because of the COLA. Without COLA, the monthly would lose to the SPIA option. With COLA, monthly ties or beats most alternatives over a long retirement.
The "lump sum + buy a SPIA" arbitrage
For many corporate pensions without COLA, the math works like this:
- Employer's monthly offer is calculated using their pension actuary's assumptions (often conservative)
- Commercial SPIA market is more efficient: higher mortality credit pricing for the same age/gender
- Result: you can often take the lump sum, buy a commercial SPIA, and get 5-15% more monthly income than the employer's monthly offer
This is one of the most common reasons independent producers recommend the lump sum. Not because we want the AUM, but because the commercial SPIA market frequently beats the employer's actuarial pricing.
When monthly absolutely wins
- Plan has FULL uncapped COLA (federal employee FERS-style, some state plans)
- You have above-average longevity expected: live past 90+
- Spouse is fully dependent on your income and you have a strong joint-survivor option
- You don't trust yourself with a lump sum (this is real: 30%+ of lump sum recipients deplete the money within 10 years per multiple academic studies)
- Tax bracket today is very high and you don't need lump sum flexibility
When lump sum absolutely wins
- No COLA on monthly; you'll lose 30-50% real purchasing power over 25 years
- Underfunded plan with PBGC-cap risk binding
- Serious health condition reducing life expectancy
- Plan offers single-life only or punitive joint-survivor reduction
- You want to leave assets to heirs
- You need IRA tax planning flexibility (Roth conversions, charitable distributions, etc.)
The lump sum trap to avoid
Taking the lump sum as taxable cash (not rolled to an IRA) is almost always a disaster. The $500K lump sum becomes ~$340K after federal + state tax, immediately. Always roll lump sums into a traditional IRA, then make purchase decisions from inside the IRA (MYGAs, SPIAs, portfolio) where tax deferral is preserved.
Already have a pension, or building your own?
A pension and an income annuity do the same job: a check for life. The difference is who paid for it and who stands behind it.
| Feature | Traditional pension | Annuity you buy |
|---|---|---|
| Who pays in | Employer (defined benefit) | You (single or multiple premiums) |
| Who backs it | Employer plus PBGC (private single-employer plans); the government sponsor (public plans) | The insurer's claims-paying ability, plus the state guaranty association |
| Backstop limit | PBGC: $7,789.77/month at 65, straight life (plans ending in 2026); multiemployer plans have a separate, lower guarantee | State guaranty association: usually $250,000 to $300,000 per owner per insurer, depending on the state |
| Inflation adjustment | Some plans, mostly public sector | Optional, at the cost of a lower starting check |
| Survivor benefit | Often joint and survivor by default | Optional: joint life, period certain or cash refund |
| Timing and portability | Starts when you retire from that employer | You pick the start age and the insurer, and can split across several insurers |
If you keep the pension, do not buy a second income stream on top of it. The pension already covers longevity. Put other savings to work for principal protection (a MYGA), growth, or liquidity. If you have no pension, or already cashed one out, an income annuity (SPIA now, deferred income annuity or QLAC later) is the only product that rebuilds one. If your plan promises more than the PBGC limit, the part above $7,789.77/month depends on the plan's own funding, which is one more point for the lump sum in the rubric above. Splitting a large annuity purchase across insurers keeps each piece inside the guaranty association limit. Source: PBGC maximum monthly guarantee table, 2026.
