In the pension lump sum vs. annuity choice, the monthly annuity often wins if you expect to live past your break-even age. It also gives you income you can’t outlive. The lump sum fits better if your health is poor, other guaranteed income covers your basics, or you want money left for heirs.
The offer tends to arrive as two lines on an election form: $2,000 a month for life, or $300,000 today. Those numbers match only at one age and one interest rate. The work is figuring out which side of that line you’re likely to land on.
How Do You Compare a Pension Lump Sum and Annuity?
You compare a pension lump sum and annuity with three numbers. They’re your break-even age, the return the pension implies, and the income the lump sum could support.
Enter your monthly pension, the lump sum offer, and the age payments start.
Start with break-even. Divide the lump sum by the annual pension. A $300,000 offer against $24,000 a year breaks even after 12.5 years, or about age 77½ if payments start at 65.
Most people collect past that point. On average, a 65-year-old man has about 18 more years and a woman about 21, according to the Social Security Administration’s life table.
| Years of payments | Age at last payment | Total pension paid | Return that matches the pension | Chance a 65-year-old lives that long (men / women) |
|---|---|---|---|---|
| 12.5 | 77½ | $300,000 | 0% (break-even) | 72% / 81% |
| 18 | 83 | $432,000 | 4.4% | 53% / 64% |
| 20 | 85 | $480,000 | 5.2% | 45% / 57% |
| 25 | 90 | $600,000 | 6.6% | 24% / 35% |
| 30 | 95 | $720,000 | 7.3% | 8% / 14% |
Source: Boldin editorial calculation for a $2,000 monthly pension paid at the end of each month from age 65, vs. a $300,000 lump sum. Returns are annual rates. Odds from the Social Security Administration’s 2023 period life table.
Read each row as the return you’d need to earn on the $300,000 to match the pension for that long. Live to 85, and the pension works like a return of about 5.2% with no market risk and no chance of running dry. Even at 90, where the pension works like a 6.6% return, about 1 in 3 women who start collecting at 65 are still alive.
Break-even age is one number. The Boldin Planner shows how either choice plays out with your Social Security, taxes, and savings into your 90s.
How Much Income Could the Lump Sum Support?
A $300,000 lump sum could support about $11,700 a year at a 3.9% starting withdrawal rate. That’s the starting point Morningstar’s research puts forward, with raises for inflation each year.
The pension pays $24,000 a year in this example. Without a COLA, inflation shrinks it, and after 20 years at 3% it buys about $13,300 in today’s dollars. That’s still more than the lump sum’s inflation-adjusted $11,700.
You can also pace withdrawals with the IRS life-expectancy tables used for required minimum distributions. Either rule is a starting point, since your other income, spending, and taxes decide what you can draw.
Why Does Your Lump Sum Change With Interest Rates?
Your lump sum changes with interest rates because plans discount your future payments to today’s dollars. They use rates the IRS sets under Section 417(e). Higher rates shrink the lump sum, and lower rates raise it.
Those minimum present value segment rates climbed from 4.50%, 4.96%, and 5.40% in August 2024 to 4.65%, 5.75%, and 6.73% in August 2026. Plans tie your offer to a set lookback month, so the same pension can produce a smaller offer a year later.
Ask your plan which month’s rates it uses and how often it updates them. A rate reset between your offer and your election can change the check.
What Are the Risks of Taking the Pension?
The pension’s main risks are inflation, the plan’s finances, and the fact that payments stop at death unless you choose a survivor option.
- Inflation. Most private pensions pay a flat amount, while many state and federal plans add cost-of-living increases. At 3% inflation, a fixed check loses about a quarter of its buying power in 10 years.
- Plan failure. The Pension Benefit Guaranty Corporation insures most private single-employer plans, up to $8,113.64 a month at age 65 for plans ending in 2027. Government pensions aren’t PBGC-insured and depend on the state or city that sponsors them.
- Nothing for heirs. Once you and any survivor die, payments end and nothing passes to your estate.
What Are the Risks of Taking the Lump Sum?
The lump sum’s main risk is running out. Markets can fall early in retirement, and sequence of returns risk can shrink a portfolio faster than average returns suggest.
Spending is the other trap. Money in hand gets used for a new roof or a family emergency, and the income plan shrinks with it. If you take the lump sum, set aside a cash reserve so planned withdrawals don’t have to cover surprises.
Investing it also takes work. You’ll choose investments, set a withdrawal pace, and adjust both for decades, often while managing taxes on every dollar you take out.
How Is a Pension Lump Sum Taxed?
A pension lump sum is taxed as ordinary income unless you roll it into an IRA or another eligible plan. A direct rollover moves the money without tax, and you pay tax later as you withdraw.
If the plan pays the money to you, it has to withhold 20% for federal income tax, according to IRS Topic 413. To roll over the full amount within 60 days, you’d have to replace that 20% from other savings.
Money you keep may also face a 10% additional tax before age 59½. One exception covers people who leave their job in or after the year they turn 55. For public safety workers in government plans, the age is 50.
How Do Survivor Benefits Change the Choice?
Survivor benefits lower your monthly pension in exchange for income that continues to your spouse after you die. Common choices are 50%, 75%, or 100% of your benefit, and the 100% option pays the smallest check.
The largest check comes with no survivor benefit. For most private plans, the law requires your spouse to sign a statement agreeing to this. For a fair comparison, weigh the lump sum against the joint-and-survivor payment your household would take.
A lump sum handles survivors another way. Whatever is left in the account passes to your beneficiaries, though nothing guarantees there will be much left.
When Does the Lump Sum Make More Sense?
The lump sum makes more sense when the math or your situation tilts against lifetime income:
- Your health or family history points to a shorter-than-average life expectancy.
- Social Security and other guaranteed income already cover your essential expenses.
- Your pension exceeds the PBGC limit and you’re worried about the plan’s finances.
- You want to leave money to heirs and have other income to live on.
- You’d use part of it to buy a lifetime annuity at a better rate than the plan offers.
A few plans offer a middle path, with some cash now and a smaller monthly check for life.
How Do You Model Both Options in the Boldin Planner?
The Boldin Planner lets you enter a pension either way. A monthly pension goes in with its start age, COLA, survivor benefit, and tax treatment. A lump sum goes in as a one-time deposit, in future dollars, to the account you choose.
Build one scenario for each option and compare savings balances, taxes, and spending into your 90s. Then fold the winner into your full retirement income plan, alongside Social Security and savings.
Pension Lump Sum vs. Annuity FAQ
Is it better to take a pension lump sum or monthly payments?
Monthly pension payments come out ahead if you collect past your break-even age. You find it by dividing the lump sum by a year of payments. After that, the pension works like a guaranteed return the lump sum would have to beat in the market. The longer you expect to live, the higher that bar climbs.
How is a pension lump sum calculated?
A pension lump sum is calculated by converting your future monthly payments into a single present value. Plans use IRS-set interest rates and a mortality table to do it. The plan’s lookback month fixes which rates apply, so the same benefit can produce different offers from one year to the next.
Do higher interest rates reduce a pension lump sum?
Higher interest rates reduce a pension lump sum, since a higher discount rate makes future payments count for less today. In a simple example, a one-point rise cuts the offer by about 8% for a 65-year-old and about 24% for a 45-year-old. If rates are climbing, an earlier election date may lock in a larger offer.
Can you roll a pension lump sum into an IRA?
A pension lump sum can roll into a traditional IRA without current tax through a direct rollover. The money keeps growing tax-deferred until you withdraw it. A check made out to you triggers 20% federal withholding, which you’d have to replace to roll over the full amount.
Can you take part of your pension as a lump sum?
Some pension plans offer a partial lump sum, paying part of your benefit in cash and the rest as smaller monthly payments. Others offer all or nothing. Your plan’s summary plan description or benefits office can tell you which options exist and how each one changes your monthly amount.
Is there a pension lump sum calculator?
A pension lump sum calculator compares your plan’s two offers: a monthly pension for life or a single payment now. Boldin’s version takes the monthly amount, the lump sum, the start age, your sex, and any COLA. It returns your break-even age, the return the lump sum would need to match the pension, and your odds of living past break-even.
