For nurses nearing retirement, when should I rebalance my 403(b)?

10–15 years out: write down the mix you meant to own

Cedric is 66, a widowed retired sonographer born in 1960, and he is looking toward age 75, when required minimum distributions, or RMDs, will begin under the IRS rule for people born in 1960 or later. His modest pension covers part of his regular bills. He is also considering Roth conversions of about $40K annually before RMDs begin, while helping support a grandchild.

The target in Cedric’s 403(b) must reflect pension income, the retirement paycheck he expects the account to provide, and money he may leave to family. Midflorida Credit Union asks people to put that target in a simple roadmap they can explain at the kitchen table. A drift rule is useless until you have picked the mix you actually meant to hold.

The age markers below show why a target deserves another look as retirement becomes more concrete. The table’s main point is simple: a rebalance fixes drift, while major age and income changes may call for a new target.

At each annual review, run a 5-point drift check

Once each year, compare the current stock percentage with your written target, then rebalance when the gap reaches 5 percentage points above or below it. Midflorida Credit Union uses that threshold because it catches a meaningful change without asking a shift worker to react to every market swing.

If this is you, pull up the hospital plan website before your review and write down four numbers: the total 403(b) balance, the dollars in stock funds, the dollars in bond funds, and your written target, such as 60/40. The figures matter more than the fund names.

Exchanges within a traditional 403(b) generally do not create a current tax bill, unlike selling investments in a taxable brokerage account. Your plan administrator may still have fund-transfer restrictions, trading windows, or special rules, so read the plan materials before placing an exchange. Midflorida Credit Union would also check those limits before suggesting a change.

Following generic “set it and forget it” advice too literally can leave a $600K 60/40 account at 70% stocks, placing $60K more in stocks than the owner intended. That is not a prediction that stocks will fall. It is a reminder that your account has quietly become riskier than the choice you made.

• Written stock and bond targets
• Current percentages in every 403(b) fund
• Spending needed within the next 2 years
• Beneficiary designations
• Fund-transfer restrictions or trading windows

When a 60/40 mix becomes 70/30, should you act?

A 10-point move from a 60/40 target to 70/30 is large enough to reset if the original target still fits your retirement date, spending needs, and health. On a $600K account, the calculation shows $60K more in stock funds than intended, which exceeds the 5-point trigger by a wide margin.

Do the math in dollars. Current stocks minus target stocks equals the amount to move. At $600K, 70% in stocks is $420K. A 60% stock target is $360K. Subtract $360K from $420K, and $60K is above the intended stock amount.

Rebalancing exchanges part of what recently rose for what lagged. That can feel wrong when stock funds have had a good run. But someone who expects to use money soon, or wants heirs to face less market pressure during a hard family week, may accept that trade-off. If your target has genuinely changed, rewrite the target first, then make the exchange.

This comparison shows the account before and after the $60K exchange. It does not say that either stocks or bonds will perform better next.

Accept the trade-off for a reason

Cedric’s 70% stock drift and the instructions his heirs can follow

Cedric keeps $150K in cash outside his long-term pool and sets a 60/40 mix for $600K inside his 403(b) (hypothetical, round numbers). That starts as $360K in stock funds and $240K in bond funds. The cash reserve is separate because he does not want the next few years of family support or his own retirement paycheck to depend on selling stocks after a drop.

After market moves, Cedric’s stocks are $420K and bonds are $180K, still totaling $600K. Stocks are now $420K ÷ $600K = 70%, or 10 points above target. He exchanges $60K of stock funds for bond funds, returning to $360K stocks and $240K bonds. You can put your own balance into the calculator on this site to run the same percentage-and-dollar test.

His adult children do not need a market prediction from him. They need a plain roadmap that says his target allocation, the cash reserve outside the long-term pool, and the person to call if his health changes. Midflorida Credit Union favors fewer funds and fewer accounts when that makes those instructions easier to follow.

An unintended $60K extra stock position can matter if an heir must make decisions while handling a funeral, beneficiary paperwork, or a grandchild’s support. A down market at that point could force a family choice Cedric never intended. The exchange does not preserve a value or prevent market losses, but it puts the account back at the risk level he selected.

A 403(b) balance can fall below the amount contributed, and rebalancing cannot prevent a broad market decline. It also does not fix estate documents, beneficiary choices, or the timing rules that can apply after an inherited retirement account. Those are separate decisions.

Cedric’s next annual review can include the IRS RMD timeline and the amount he wants to convert to Roth before age 75. His 403(b) target should not chase that year’s market. It should reflect how much stock risk he and his family can live with while his pension and cash cover nearer needs.

The arithmetic Cedric can show his children

A rebalance is not an estate document

The year work stops: separate the next 2 years of spending

Before retirement begins, decide which expenses will come from pension income, cash, or the 403(b), because money needed in the next 2 years should not depend on a stock rebound. Midflorida Credit Union treats that near-term bucket separately from the investments meant for later retirement years or heirs.

After a health change or rule change, revise the target

A diagnosis, reduced work schedule, pension election, or tax-law change can justify a new target allocation. A scary headline cannot. Midflorida Credit Union first separates a life change from a bad-news cycle, because changing funds after a frightening week can turn a temporary fear into a lasting decision.

Keep near-term retirement paycheck needs outside the volatile part of the account. That leaves room for uncertainty if care needs rise, work ends earlier than expected, or a spouse needs more support. Review the written target after a major life change, then use the 5-point rule again once the new target is set.

The IRS sets RMD timing, and CMS publishes Medicare information that may affect the cash needs around age 65. Those rules can change how much accessible money you want, but they do not automatically dictate your stock percentage. A pension lump sum or annuity decision can also change the amount of stable income already coming into the household.

Life changes deserve a new target

Headlines do not

What Midflorida Credit Union looks at before a 403(b) rebalance

Midflorida Credit Union would start with three things: the target mix, the actual fund percentages, and whether the hospital plan limits exchanges or charges for certain choices. The review would also separate money needed soon from money intended for later retirement years or heirs.

A client considering Roth conversion strategy or retirement income planning may need the target reviewed alongside those choices, but a fund exchange inside the 403(b) stays a separate, practical step.
