Key Takeaways
- A lifetime-income illustration translates an account balance into estimated monthly payments under stated assumptions.
- The illustration is not a promised payout, an annuity purchase or a complete forecast of your retirement income.
- Read the assumptions and compare the estimate with your household budget before changing contributions or investments.
A 401(k) statement may show both an account balance and estimated monthly lifetime income. The two figures answer different questions. The balance describes money in the account at the statement date. The income illustration estimates a payment stream using a specified method; it does not turn the account into a guaranteed pension.
Find the explanation beside the number
The Department of Labor’s lifetime-income resources describe the disclosure framework for covered defined contribution plans. It requires two lifetime-income illustrations at least once every 12 months. That does not mean a new illustration must appear on every quarterly statement.
Read the explanation supplied with your own statement. Check the statement period, balance used and the assumptions attached to each amount. If your portal also shows a retirement projection, establish whether that is the required illustration or a separate planning tool with different inputs.
Separate the two payment examples
Under the DOL’s standard illustration assumptions, the single-life annuity example pays a fixed monthly amount during the participant’s lifetime, with no survivor payment after death. The qualified joint-and-100%-survivor example continues the same fixed monthly amount to a surviving spouse after the participant dies.
For the standard illustration, the spouse is assumed to be the participant’s age even if the participant is unmarried or has a spouse of a different age. These are calculation assumptions. They do not establish your marital status, change a beneficiary designation or select a payout option for you.
Check the assumed age and timing
The standard calculation assumes payments begin on the last day of the statement period and that the participant is age 67, or their actual age if older. A younger worker should not read that figure as an offer to begin receiving the illustrated amount immediately.
The standard method also uses a specified Treasury interest rate and mortality table. Changes in the account balance or assumptions can change the illustration between statements. The DOL describes special rules for some in-plan annuity arrangements, so ask the administrator which method applies rather than assuming every statement is identical.
Recognize what the estimate leaves unanswered
A conversion of today’s balance does not tell you the account’s actual balance at a future retirement date. Future contributions, investment results, costs, withdrawals and the eventual payout arrangement can change the outcome. The DOL explicitly explains that these illustrations are not guarantees.
The statement is also not a complete household budget. It does not, by itself, establish what your Social Security, other pension, spouse’s income or living costs will be. Check whether any amount you are comparing is before tax, how inflation would affect spending and what survivor protection your household actually needs.
Use the number to organize the next questions
List essential and irregular retirement expenses, then list income sources separately with their expected dates and conditions. Use the illustration as one reference point without counting the same account twice: once as spendable savings and again as a separate guaranteed income source.
Ask the plan administrator:
- Which balance, date and assumptions produced this illustration?
- Does the plan offer an actual annuity option, or is this only a disclosure?
- How does any separate projection account for future contributions, returns, fees and taxes?
- Where can I read the actual distribution options and their conditions?
If you consider an annuity, compare its actual contract, costs, access restrictions, insurer obligations and survivor terms separately. Seeing an illustration does not require buying one. If you increase contributions instead, check current limits, the employer match and cash available for household bills.
The useful result is a clear set of assumptions and a manageable planning question. Neither a reassuring number nor a disappointing one is a reason to make an immediate investment change without that context.
