Pension Lump Sum vs Monthly Decision Guide

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 — a major argument for 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 — monthly wins. Die before — lump sum wins.
Carrier / plan risk. Private pensions are PBGC-backed up to ~$7,107/month for retirees at age 65 (2026 limit). 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 — 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 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.

Frequently Asked Questions

Can I take a partial lump sum and partial monthly?

Some pensions offer this; many don't. If your plan allows a 'partial lump sum option' or 'PLOP,' it can be the best of both worlds — lock some guaranteed income, take some flexibility. Check your summary plan description.

What is PBGC and does it cover my pension?

Pension Benefit Guaranty Corporation insures most private-sector defined-benefit pensions. 2026 maximum guaranteed monthly benefit at age 65 is ~$7,107. Above that, you're unsecured if the plan terminates. Public pensions (federal, state, municipal) are NOT covered by PBGC — they have separate state-level protections.

Should I roll my pension lump sum into an IRA or take it as cash?

Almost always IRA. Taking lump sum as cash triggers full federal + state income tax in the year received, often pushing you into the 32-37% bracket. IRA rollover preserves tax deferral — you only pay tax as you withdraw.

Can I buy a commercial SPIA with my pension lump sum and get more income than the employer offer?

Often yes — especially for corporate (non-COLA) pensions. Commercial SPIAs benefit from broader longevity pooling and competitive carrier pricing. 5-15% more monthly income is common. Always quote both before deciding.

What if my pension offers COLA — does that change everything?

Yes. Full or partial COLA dramatically improves the monthly option's real-value return over a 25-30 year retirement. Most commercial SPIAs do not offer true CPI-linked COLA, so an inflation-protected employer pension is genuinely hard to replicate.

Should I take single-life or joint-and-survivor pension if I'm married?

Depends on spouse's income, your relative ages, and whether 'pension maximization' (single life + life insurance on the pensioner) beats joint-survivor for your specific situation. Run both before deciding.

How does the lump sum offer compare to actuarial fair value of the monthly?

The lump sum is calculated using employer-friendly discount rates that often make the lump sum 5-15% lower than the actuarial fair value of monthly. This is normal but worth knowing — when the monthly option is much better than the lump sum, the employer is offering you a poor lump sum, not an unusually generous monthly.

What happens to my pension if I die before claiming it?

Depends on plan terms. Some pensions pay a death benefit to spouse or beneficiaries; some pay nothing. A lump-sum-then-IRA rollover converts the pension into an inheritable asset, which is often valuable for legacy purposes.
