Pensions last for your lifetime, but the length of payments depends on the type of pension you have and the choices you made when you started receiving it

A defined benefit pension — the kind most commonly offered by government employers, unions, and some large corporations — pays you a fixed amount every month for as long as you live. The payments do not stop at a certain age or after a set number of years. When you die, the pension stops, though some pensions continue paying a reduced amount to a surviving spouse or designated beneficiary.

A defined contribution pension — which includes 401(k)s, 403(b)s, and similar plans — works differently. The money in your account is yours to manage. How long it lasts depends entirely on how much you have saved, how much you withdraw each year, and how long you live. You can run out of money if you withdraw too quickly, or you can stretch it across decades if you withdraw slowly. Some people convert these accounts into an annuity, which then pays a fixed amount for life, similar to a traditional pension.

The choices you make when you start your pension matter enormously. Most pensions offer you options at the moment you retire, and those choices lock in how long and how much you receive.

Key Takeaways

  • A defined benefit pension pays you the same amount every month for your entire life, regardless of how long you live.
  • The amount you receive depends on choices you made when you started the pension — such as whether you took a lump sum, a reduced payment with survivor benefits, or a full payment with no survivor option.
  • A defined contribution plan (like a 401(k)) lasts only as long as the money in your account lasts, unless you convert it to an annuity.
  • If you die before your spouse, some pensions continue paying a reduced amount to your surviving spouse; others stop entirely depending on the option you chose.
  • Your pension's purchasing power may decline over time if it does not include a cost-of-living adjustment, meaning the same dollar amount buys less as prices rise.

How pension payout options affect how long you receive payments

When you reach retirement age and become may be able to access to start your pension, your employer or pension administrator gives you choices about how to receive your money. These choices determine both the amount you get each month and what happens to the pension if you die.

The most common options are: a single life annuity, which pays the highest monthly amount but stops when you die; a joint and survivor annuity, which pays a lower monthly amount but continues paying a reduced percentage (often 50 or 75 percent) to your spouse after you die; and a period certain option, which guarantees payments for a set number of years (such as 10 or 20 years) even if you die, with the remainder going to your beneficiary. Some pensions also offer a lump sum option, where you receive all the money at once and it becomes your responsibility to manage.

If you choose single life, you receive the most money each month, but your spouse receives nothing after you die. If you choose joint and survivor, your monthly payment is lower, but your spouse is protected. The reduction in monthly payment depends on your ages and life expectancy — the younger your spouse, the larger the reduction, because the pension fund expects to pay out for longer.

Defined benefit pensions and lifetime payments

A defined benefit pension is designed to last your entire life. The pension fund calculates your monthly payment based on your salary history, years of service, and age at retirement. Once you start receiving payments, that amount is locked in (unless your pension includes a cost-of-living adjustment, which some do and some do not).

The pension fund itself pools money from many workers and retirees, so it can afford to pay people who live into their 90s or beyond. Your individual longevity does not matter — whether you live to 70 or 100, you receive the same total monthly payment. This is the core protection a defined benefit pension offers: you cannot outlive it.

However, the purchasing power of that payment may decline. If your pension pays $2,000 per month and does not adjust for inflation, that $2,000 will buy less in 10 years than it does today. Some pensions include an automatic cost-of-living adjustment (COLA), usually 2 or 3 percent per year, which means your payment grows slightly each year. Others offer a one-time COLA at a certain age, such as 65 or 70. Many offer no adjustment at all. Check your pension documents or contact your pension administrator to find out whether yours includes any adjustment.

Defined contribution plans and how long the money lasts

If you have a 401(k), 403(b), or similar defined contribution plan, the money lasts only as long as you make it last. You own the account, and you decide how much to withdraw each year. If you withdraw $50,000 per year from a $500,000 account, the money will last about 10 years (before investment returns or losses). If you withdraw $20,000 per year, it could last 25 years or more.

The challenge is that you do not know how long you will live, so you do not know how much is safe to withdraw. Withdraw too much and you run out of money. Withdraw too little and you live below your means when you could have spent more.

One way to convert a defined contribution plan into a lifetime income stream is to purchase an annuity with some or all of the money in your account. An annuity is a contract with an insurance company: you give them a lump sum, and they pay you a fixed amount every month for life. The monthly payment depends on your age, sex, and current interest rates. A 65-year-old man with $300,000 might receive around $1,200 to $1,500 per month for life, depending on the insurance company and the type of annuity. A 75-year-old with the same amount would receive more per month, because the insurance company expects to pay out for fewer years.

You do not have to annuitize your entire account. Many people keep some money in their account to withdraw as needed and annuitize the rest to create a may provide income floor.

What happens to your pension if you die

If you chose a single life annuity, your pension stops when you die. Your beneficiary receives nothing. This is why single life pays the highest monthly amount — the pension fund does not have to budget for payments after your death.

If you chose a joint and survivor annuity, your surviving spouse receives a percentage of your monthly payment for the rest of their life. The most common arrangement is 50 percent survivor, meaning your spouse receives half of what you were receiving. Some pensions offer 75 percent survivor, where your spouse receives three-quarters of your payment. Your spouse must have been married to you at the time you started the pension; remarriage after you retire does not change the beneficiary.

If you chose a period certain option, such as 10 years certain, and you die after 6 years of payments, your beneficiary receives the remaining 4 years of payments. Once the period ends, the pension stops entirely.

If you took a lump sum and invested it yourself, what happens to the money after you die depends on how you titled the account and what your will says. The money becomes part of your estate and passes to your heirs according to your will or your state's inheritance laws.

Cost of living and how inflation affects pension value

A pension that does not adjust for inflation loses purchasing power every year. If your pension pays $2,000 per month and inflation averages 3 percent per year, your payment buys about 26 percent less in 10 years, and about 48 percent less in 20 years. This matters most if you retire in your 50s or 60s and expect to live 30 or 40 years.

Some pensions include an automatic cost-of-living adjustment tied to the Consumer Price Index (CPI). Others offer a fixed increase, such as 2 percent per year, regardless of actual inflation. Some offer a one-time adjustment at a certain age. Many offer no adjustment at all.

When you are deciding whether to take a lump sum or monthly payments, or whether to choose single life or joint and survivor, ask your pension administrator whether your pension includes any COLA. If it does not, factor inflation into your long-term planning. Money that seems adequate today may not be adequate in 20 years.

Frequently Asked Questions

Can my pension run out of money?

A defined benefit pension cannot run out of money — it pays you for life. A defined contribution plan (401(k) or similar) can run out if you withdraw too much each year. If you convert your defined contribution plan to an annuity, it cannot run out either, because the insurance company guarantees the payments.

What if I die shortly after I start receiving my pension?

If you chose single life, your beneficiary receives nothing and the pension stops. If you chose joint and survivor or period certain, your beneficiary receives the remaining payments according to the option you selected. This is why many people choose joint and survivor even though it reduces their monthly payment.

Does my pension payment change if I work after I retire?

Some pensions reduce or suspend your payment if you continue working, especially if you work for the same employer. Others do not. Check your pension plan documents or contact your administrator. If you have a defined contribution plan, working does not affect your pension payments at all.

What happens to my pension if I move to another state or country?

Your pension payments continue regardless of where you live. You can move anywhere and keep receiving your monthly payment. However, some states tax pensions differently, and some countries have tax treaties with the United States that affect how your pension is taxed. Consult a tax professional before moving if you are concerned about tax implications.

Can I change my pension payout option after I start receiving payments?

Once you have chosen your payout option and started receiving payments, you cannot change it. This is why the choice matters so much. Take time to understand your options and discuss them with your spouse and a financial advisor before you commit.
