Monthly pension vs. lump sum, side by side
| What matters to you | Monthly Pension | Lump Sum |
|---|---|---|
| Guaranteed for life | Yes, a check every month | No, you manage it |
| Access to principal | No, you can't tap the balance | Yes, full control |
| Survivor benefit | Only if you elect a joint option (lowers the payment) | Whatever is left passes on |
| Inflation protection | Usually none, since most are fixed | Depends how you invest it |
| Legacy to heirs | Little to none once both spouses pass | Remaining balance goes to heirs |
| Longevity risk | Carried by the plan, so you can't outlive it | Carried by you, so it could run out |
This is a general comparison. Your actual choice depends on your pension's specific terms, your age, health, and household finances. Compare your own options below.
Tax note: a lump sum paid to you is taxable income that year, and the plan must generally withhold 20% for federal tax. A direct rollover to an IRA avoids both and keeps the money tax-deferred (IRS Topic 413, rollovers from retirement plans). Monthly pension payments are taxed as ordinary income as you receive them (IRS Topic 410).

How do you calculate a pension's payout rate?
The single most useful number is your pension's payout rate: take your annual pension and divide it by the lump-sum offer. If a plan offers $2,000 a month ($24,000 a year) or a $360,000 lump sum, the payout rate is $24,000 ÷ $360,000 = 6.7%.
Why it matters: to pay yourself the same check from interest alone, without touching the lump sum, you'd need to earn that rate every year, for life. If you also spend the lump sum down, the return you need depends on how long you live. In this example, paying yourself $2,000 a month from $360,000 lasts 15 years at a 0% return. It takes about 3.0% a year to last 20 years, 4.5% to last 25 years and 5.3% to last 30 years (RLF arithmetic, level monthly payments, before tax, checked October 10, 2026). The higher the payout rate and the longer you live, the harder the pension is to match. As a rough guide, payout rates above about 6 to 7% make the monthly pension tough to beat, while lower rates leave more room for the lump sum to win, especially if you have other priorities like legacy or flexibility.
Which questions decide lump sum versus monthly pension?
The math sets the stage, but your personal situation usually makes the call. Walk through these:
| Question | Leans toward pension | Leans toward lump sum |
|---|---|---|
| Your health & longevity | Good health, family history of long life | Serious health concerns, shorter horizon |
| Your spouse | Spouse needs income after you're gone (with a joint option) | No survivor need, or spouse well-provided for |
| Other guaranteed income | Little else besides Social Security | Already have strong guaranteed income |
| Legacy goal | Leaving money to heirs isn't a priority | You want to pass on a larger inheritance |
Notice how the same choice can be right for one household and wrong for another. A healthy couple with no other pension may lean toward the guaranteed check; a single retiree with health issues and grown kids may lean toward keeping the lump sum.
Don't forget what a pension quietly protects against
A monthly pension removes two risks most people underestimate: longevity risk (outliving your money) and sequence-of-returns risk (a bad market early in retirement doing outsized damage). A lump sum hands both risks to you, along with all the upside and control. Neither choice is "safe" or "risky" in the abstract; they simply shift who carries the risk. The right answer is the one that matches how much certainty you want versus how much control you want.

What is the difference between a lump sum and an annuity?
A lump sum is one payment of the pension's present value that you manage yourself. An annuity here means the monthly pension: a fixed payment for life, with the plan carrying the investment and longevity risk. If the lump sum is rolled directly into an IRA, no tax is withheld; if it is paid to you, the plan generally withholds 20% and the whole amount is taxable income that year.
Is there a pension lump sum vs annuity calculator?
The core calculation is simple. Divide the annual pension by the lump-sum offer. A $2,000 monthly pension ($24,000 a year) against a $360,000 lump sum is a 6.7% payout rate, and the lump sum takes 180 months, or 15 years, of pension payments to match before any investment growth or inflation. Then ask whether you could safely draw that much from $360,000 yourself.
Should I take my pension as a lump sum or monthly payments?
There's no universal winner. Take the monthly pension if you value guaranteed lifetime income and don't have a strong survivor or legacy need. Take the lump sum if you want control, flexibility, a larger legacy, or think you can generate more income yourself. Start with the payout rate: above roughly 6 to 7%, the monthly pension is often hard to beat.
What is a pension payout rate and why does it matter?
It's your annual pension divided by the lump-sum offer. A $2,000/month pension ($24,000/year) against a $360,000 lump sum is a 6.7% payout rate. The higher the rate, the harder it is to replicate the pension on your own, because that is the return you'd have to earn every year, for life, to pay the same check without touching principal.
Does my health affect the decision?
It can. A monthly pension pays off most when you (and your spouse, with a joint option) live a long time. If you have serious health concerns and no survivor need, the lump sum may return more of your money to you or your heirs. Expecting a long retirement tilts toward the guaranteed check.
