Your employer’s pension plan offers a choice: $2,100 a month for life, or a one-time lump sum of $340,000. The lump sum looks large. The monthly payments look secure. The decision is usually irreversible, so it deserves careful thought.
Key Takeaways
- A monthly annuity provides guaranteed lifetime income, protecting against outliving your money; a lump sum provides control and flexibility.
- Lump-sum amounts are calculated using interest rates and mortality tables; higher interest rates generally produce smaller lump sums.
- Married retirees should consider joint and survivor options, which usually require spousal consent to waive.
- Health, other guaranteed income, investment discipline and the plan’s financial strength all matter.
This is general information. Consider getting advice from a fee-only financial planner before deciding.
What the monthly annuity offers
A pension annuity pays a fixed monthly amount for life. Options typically include:
- Single life annuity: highest monthly payment, ends at your death.
- Joint and survivor annuity: lower monthly payment that continues to a surviving spouse, often at 50%, 75% or 100%.
- Period certain: payments guaranteed for a minimum number of years.
Most private pensions do not adjust for inflation, so purchasing power declines over time. Some public pensions include cost-of-living adjustments.
What the lump sum offers
A lump sum gives you the present value of your pension in cash. You can roll it into an IRA to defer taxes, invest it, and withdraw as needed. Any remaining balance can pass to heirs.
But you take on investment risk and longevity risk — the risk of living longer than your money lasts.
How lump sums are calculated
Plans calculate lump sums using interest rates and mortality assumptions set under federal rules. When interest rates are higher, lump sums are smaller, because the future payments are discounted more heavily. When rates are lower, lump sums are larger.
A simple comparison method
Compare the lump sum with what it would cost to buy similar guaranteed income elsewhere:
- Get an annuity quote from an insurance company for the same monthly income and survivor options.
- Compare with the lump sum. If buying the same income would cost more than the lump sum, the pension annuity is relatively valuable.
You can also calculate the implied return needed for the lump sum to match the pension payments over your expected lifetime.
Factors that favour the annuity
- Good health and family longevity
- Little other guaranteed income besides Social Security
- A spouse who depends on survivor income
- Discomfort with investing or market volatility
- Desire for simplicity
Factors that favour the lump sum
- Serious health conditions that shorten life expectancy
- Substantial other guaranteed income
- A desire to leave money to heirs
- Confidence and discipline in managing investments
- Concerns about the plan’s financial health
Pension protection
Most private-sector defined benefit pensions are insured by the Pension Benefit Guaranty Corporation (PBGC) up to legal limits. If a plan fails, the PBGC pays benefits up to a maximum that depends on age and payment form. Most retirees’ benefits fall within the limits, but very high pensions may not be fully covered.
Government pensions are not covered by PBGC but are backed by public employers.
Spousal consent
For married participants in many private pensions, the default form of payment is a joint and survivor annuity. Choosing a single life annuity or lump sum usually requires your spouse’s written, notarised consent.
Tax considerations
- Monthly payments are generally taxed as ordinary income as received.
- A lump sum rolled directly into an IRA defers taxes.
- A lump sum paid to you directly is subject to mandatory withholding and may be fully taxable, possibly with penalties if you are under 59½.
Frequently Asked Questions
Can I take part lump sum and part annuity? Some plans offer partial lump sums. Check your plan’s options.
Can I change my mind later? Usually not. Once payments start or the lump sum is paid, the decision is final.
Does the lump sum include survivor benefits? The lump sum replaces all future payments, including survivor benefits.
What if interest rates change before I retire? Lump-sum values can change from year to year. Check how your plan updates rates.
The bottom line
A pension annuity is longevity insurance; a lump sum is flexibility. Compare the lump sum with the cost of buying similar guaranteed income, weigh your health, spouse and other income, and decide carefully, because the choice is usually permanent.
