At 46, Midflorida Credit Union shows investment mistakes nurses make can change a $60K account by about $25K over 10 years, assuming 5% versus 2%. This applies to nurses with several hospital accounts, including a travel nurse whose newest 403(b) defaulted into cash after enrollment.
Holding cash can feel safer after a bad month, while investing for another decade means accepting market swings. Most people underrate the years lost while they wait to feel settled. Midflorida Credit Union puts each account, its job, and its next review date on a one-page retirement roadmap clients can explain at home.

Age 46: the default-fund decision
Ingrid is 46, single, and works travel contracts. Her $510K is spread across 7 small workplace accounts and an IRA. One $60K 403(b) has not been reviewed since enrollment, when it landed in a cash-like default after a market scare (hypothetical, round numbers).
The belief sounds harmless: “I will move it after things settle down.” But waiting is a timing choice. A 10-year gap cannot be made whole just by picking a different fund later, because the dollars missed 10 years of compounding.
Assuming 5% annually for illustration, $60K × 1.05^10 equals about $97,734 after 10 years. Assuming 2% annually, $60K × 1.02^10 equals about $73,139. $97,734 minus $73,139 equals $24,595. The site calculator can run this same kind of side-by-side calculation with your own balance and time frame.
A diversified investment mix can lose value, sometimes ending a bad year worth less than what went in, and the higher assumed return is not a forecast. Ingrid checks fund choices, expenses, and transfer rules before changing this account. Midflorida Credit Union would not treat a cash balance as automatically wrong until the money’s purpose is known.
The 10-year cost of waiting
Cash has a job, but not every job
If an account has not been reviewed since enrollment or a job change, identify its fund, expense ratio, cash balance, and beneficiary record before adding another contribution or making a market-driven switch.
| Comparison point | Cash-like default | Diversified mix |
|---|---|---|
| Starting balance | $60K | $60K |
| Annual assumption | 2% | 5% |
| Value after 10 years | $73,139 | $97,734 |
| Growth above starting balance | $13,139 | $37,734 |
| Difference after 10 years | — | $24,595 |
What should a nurse in the 50s change?
Turning 50 is a prompt to review savings and investment choices together: the IRS limit for 2026 is $24,500 for employee 403(b) deferrals, plus an $8,000 age-50 catch-up, or $32,500 total if the hospital plan permits it. Raising contributions while leaving new money in an old default can weaken the benefit of those catch-up years.
Ages 60–63: revise the old savings target
A nurse ages 60–63 may be able to defer $35,750 in 2026, because the IRS regular employee limit is $24,500 and the higher catch-up is $11,250, subject to the hospital plan and eligibility. A savings target written years ago may miss this chance to put more of the final working years to work.
At what ages do these investment mistakes nurses make deserve a fresh look? The timeline answers that by pairing each age range with the account task that usually matters then. It is a reminder to check the plan’s payroll rules before assuming the larger catch-up will happen automatically.
| Age or stage | What happens | What to do |
|---|---|---|
| 46 | $60K sits in default cash | Review fund and expenses |
| 50–59 | $32,500 possible deferral | Revisit savings target |
| 60–63 | $35,750 possible deferral | Use higher catch-up if eligible |
| 5 years from retirement | Cash needs become nearer | Set cash purpose |
5 years before leaving: stop reacting to the last bad month
About 5 years before leaving work, choose a documented investment mix and a stated cash amount for near-term bills; do not reset the whole account after each frightening month. A nurse this close to retirement may need less stock exposure than at 46, yet still needs growth for years of retirement spending.
Selling an entire account into cash after a frightening month, then waiting for a perfect re-entry point, puts the timing mistake in charge. The money may miss recovery years that still matter. This is not an argument for keeping every dollar invested. It is an argument for deciding what cash must do before a drop in the market makes the decision for you.
A 61-year-old with 1 year of expenses already set aside has a reason to hold cash: bills due soon. A 46-year-old with 15 more working years ahead is in another position if $60K sits in cash only because of an old scare, since that money may not be spent for decades. Midflorida Credit Union reviews the pension, 403(b), and other accounts together before suggesting a change in stock exposure.
The closer retirement gets, the more useful the label on each dollar becomes. Near-term bills might sit in cash. Money intended for later retirement years needs a separate choice. Retirement income planning can help turn that separation into a retirement paycheck without pretending markets will move on schedule.
Cash for bills has a specific purpose
A scare should not rewrite retirement
Which account answers should make you pause?
Pause when HR, the benefits office, or a custodian cannot identify the current investment, show a current statement, or explain where expenses appear. A default fund is not automatically right for your retirement date, 4 untouched accounts are not proof of diversification, and a stable-value or money-market holding is not a full long-term investment choice.
Run this list against every account before making another payroll change. It takes less time than trying to reconstruct 6 employers’ choices a few years before retirement.
The answers to get in writing
Four accounts can own the same funds
Ask which fund is the default, whether the account accepts changes, where expenses appear, and whether a former employee still has online access. An answer that cannot be documented is a reason to pause before moving money.
- Investment name and expense ratio
- Target-date year, if used
- Cash balance and its purpose
- Beneficiary record
- Contribution setting
- Date of the last review
Midflorida Credit Union’s first account review
Midflorida Credit Union first puts each account on 1 inventory: balance, fund choice, cash position, expense information, beneficiary record, and the purpose it serves in the retirement roadmap. The review does not assume every old account should move.
We identify the $60K sitting in cash, overlapping funds, and questions that need a written answer from the employer or custodian. Account consolidation or a 403(b) rollover may fit later, but only after the account facts are on the page.
The missed time, not one bad fund choice, creates the $24,595 gap.
