Annuity vs. pension comes down to who funds it and who controls it. A pension is retirement income your employer funds and promises. An annuity is a contract you buy from an insurance company with your own money.
Both can pay you a guaranteed check for life, and a pension’s monthly payout is itself technically called an annuity. The real decision most people face is whether to take a pension’s monthly annuity or its lump sum. Below we compare the two side by side and show how to run that math.
- A pension is funded by your employer, and you don’t choose the investments or the insurer.
- An annuity is bought by you from an insurer, with the terms you pick.
- Different safety nets: private pensions are backed by the PBGC, while annuities are backed by the insurer and your state guaranty association.
- Lump sum or monthly: compare your pension’s monthly offer with what the lump sum would buy in an immediate annuity. Keep whichever pays more.
- Gender matters: pension lump sums use a unisex life table, so the monthly pension is often the better deal for women.
Annuity vs. Pension: The Key Differences
| Feature | Pension | Annuity |
|---|---|---|
| Who pays for it | Your employer (sometimes with your contributions) | You, with savings, a rollover or a pension lump sum |
| Who sets the terms | The plan | You choose the insurer, product and payout |
| How income is set | Formula based on salary and years of service | Your premium, age and the insurer’s rates |
| Backstop if it fails | PBGC (private plans), up to federal limits | State guaranty association, often $250,000 per insurer |
| Cost-of-living raises | Rare in private plans, common in public plans | Optional rider, for a lower starting check |
| Can you shop around? | No | Yes, quotes vary between insurers |
| Taxes | Ordinary income | Ordinary income on IRA money, or on the earnings for after-tax money |
What Is a Pension?
A pension, or defined benefit plan, promises you a set monthly income in retirement. The amount usually comes from a formula such as 1.5% of your final average salary for each year you worked. Your employer invests the money and carries the risk if the investments fall short.
- You don’t pick anything: the plan sets the investments, the formula and the payout options.
- Income starts at the plan’s retirement age: usually 65, often with reduced early benefits from 55.
- Most offer a choice at retirement: a lifetime monthly annuity, a joint-and-survivor annuity, and sometimes a lump sum.
What Is an Annuity?
An annuity is a contract you buy from an insurance company. You hand over a premium, and the insurer promises growth, income or both. The type that works most like a pension is an immediate annuity (SPIA), which turns a lump sum into a guaranteed monthly check within about 30 days.
- You choose the insurer: stick with carriers rated A- or better by AM Best.
- You choose the payout: life only, life with a period certain, or joint life for a couple.
- You can shop: quotes for the same premium can differ by several percent between insurers.
Is a Pension an Annuity?
Partly. When a pension pays you monthly for life, that payment stream is legally an annuity, which is why plan paperwork says “single life annuity” or “joint and survivor annuity.” The difference is that a pension annuity is paid by your employer’s plan, while a commercial annuity is paid by an insurer you chose.
The two can also merge. In a pension risk transfer, your employer buys a group annuity from an insurer to take over its pension payments. When that happens, the insurer pays your benefit, and your backstop shifts from the PBGC to your state guaranty association.
Which Is Safer, a Pension or an Annuity?
Both are very safe when they are well funded, but they are protected by different safety nets.
- Private pensions: the Pension Benefit Guaranty Corporation (PBGC) insures them. For a plan that ends in 2026, it guarantees up to $7,789.77 a month for a retiree starting at 65 with a straight-life annuity, so most retirees are fully covered.
- Government pensions: these are not PBGC-insured. They rely on the state or city that sponsors them.
- Annuities: the insurer backs them first, then your state guaranty association. Most states cover up to $250,000 per owner per insurer, so larger amounts are often split between insurers.
Pension Lump Sum vs. Annuity: Which Should You Take?
If your plan offers a lump sum, the best test is simple. Compare the plan’s monthly payment with what the lump sum would buy from an insurer.
- Find your two offers: the monthly annuity and the lump sum from your plan’s election packet.
- Get an immediate annuity quote for the lump sum amount, at your age and with the same payout type. Our immediate annuity calculator gives a starting estimate.
- Compare the checks: if the pension pays more, keep the pension. If the insurer pays meaningfully more, the lump sum may be worth taking.
Example: Mike is 65. His plan offers $2,000 a month for life or a $300,000 lump sum. In 2026 surveys, $300,000 buys a 65-year-old man roughly $1,890 to $2,040 a month in a life-only immediate annuity. Mike’s pension sits inside that range, so he gains little by cashing out unless he wants the money for other reasons.
Why Women Often Do Better Keeping the Pension
Pension lump sums are calculated with a unisex life expectancy table. Insurers price private annuities by sex, and women receive less per month because they live longer on average.
- For a woman: the unisex lump sum assumes a shorter life than hers, so it usually buys less income than the pension pays. The monthly pension tends to win.
- For a man: the lump sum can buy a slightly bigger private annuity check. It is worth getting a quote.
When Interest Rates Matter
Plans convert your monthly benefit into a lump sum using IRS corporate bond rates under Section 417(e). When those rates rise, lump sums shrink. When they fall, lump sums grow.
Many plans lock in their lump sum rates for a full plan year and update them on January 1. Ask your plan which rates apply to your retirement date before you choose.
Reasons to Keep the Monthly Pension
- It pays as much or more than the lump sum would buy from an insurer, which is common for women and for married couples.
- You want zero decisions: no investing, no withdrawal plan and no insurer to pick.
- Your plan is well funded or your benefit is under the PBGC limit.
- Your pension has a cost-of-living adjustment, which is very expensive to buy in a private annuity.
Reasons to Take the Lump Sum
- You want something left for heirs: a life-only pension stops at death, while a lump sum you invest can pass on.
- You have serious health problems that make a long retirement unlikely.
- You already have enough guaranteed income from Social Security and other sources. See how Social Security and annuities work together.
- Your employer’s plan is badly underfunded and your benefit is above the PBGC limit.
- You can buy a better annuity yourself, or you want to annuitize only part and invest the rest. Our annuity income floor strategy shows how to split it.
How Pension and Annuity Income Are Taxed
Pension payments are taxed as ordinary income in the year you receive them. A pension lump sum is also fully taxable unless you move it into an IRA.
- Do a direct rollover: send the lump sum straight to an IRA or an IRA annuity, and no tax is due yet.
- Avoid taking the check yourself: the plan must withhold 20% for taxes, and you have 60 days to roll the money over.
- Under 59½: a lump sum you keep may also owe a 10% penalty, with some exceptions for people who leave their job at 55 or later.
- Annuity income: an annuity bought with IRA money is fully taxable. One bought with after-tax savings is taxed only on its earnings. See how annuities are taxed for the details.
Annuity vs. pension is rarely an either-or choice. The smartest move is usually to take whichever form pays you the most guaranteed income, then fill any gap with an annuity you shop for yourself.
Frequently Asked Questions
What is the difference between a pension and an annuity?
A pension is retirement income funded and promised by your employer, with terms set by the plan. An annuity is a contract you buy from an insurance company with your own money, choosing the insurer and payout yourself. Both can provide guaranteed income for life.
Is a pension an annuity?
A pension’s lifetime monthly payment is technically an annuity, which is why plans use terms like “single life annuity.” The difference is the payer. A pension annuity comes from your employer’s plan, while a commercial annuity comes from an insurer you chose.
Should I take a pension lump sum or monthly payments?
Get an immediate annuity quote for your lump sum amount and compare it with the pension’s monthly offer. If the pension pays the same or more, monthly payments are usually the better deal. A lump sum can make sense if you want to leave money to heirs, have health concerns or already have enough guaranteed income.
Which is safer, a pension or an annuity?
Both are generally safe. Private pensions are insured by the PBGC, up to $7,789.77 a month at age 65 for plans ending in 2026. Annuities are backed by the insurer and then by state guaranty associations, which typically cover up to $250,000 per owner per insurer.
Can I roll a pension lump sum into an annuity?
Yes. A direct rollover moves the lump sum into an IRA without tax, and the IRA can buy an annuity. Monthly pension payments themselves cannot be rolled over once they start.
