What Is the Amentum 401(k) Plan?
A 401(k) is a tax-advantaged retirement savings account offered by employers. The Amentum 401(k) plan follows the same structure but comes with specific features tailored to Amentum employees. Like most 401(k) plans, it allows you to contribute a portion of your pre-tax salary, reducing your taxable income while building a nest egg for retirement.
Key Features of the Amentum 401(k)
- Pre-Tax Contributions – Money goes into the 401(k) before taxes are deducted, lowering your taxable income.
- Employer Matching – Amentum may match a percentage of your contributions, essentially giving you free money.
- Investment Options – The plan offers a range of funds, including stocks, bonds, and target-date funds.
- Tax-Deferred Growth – Investments grow tax-free until withdrawal in retirement.
How Much Can You Contribute?
The IRS sets annual contribution limits for 401(k) plans. For 2024, the limit is $23,000 for employees under 50 and $30,500 for those 50 or older (including catch-up contributions).
If Amentum offers a match, the formula varies. A common structure is a 50% match on the first 6% of salary. Here’s how that works:
- Example: If you earn $80,000 and contribute 6% ($4,800), Amentum adds $2,400 (50% of $4,800).
The Power of Compound Interest
One of the strongest advantages of a 401(k) is compound growth. The formula for future value of an investment with compound interest is:
FV = P \times (1 + r)^nWhere:
- FV = Future Value
- P = Principal investment
- r = Annual return rate
- n = Number of years
Example: If you invest $10,000 at an average 7% annual return over 30 years:
FV = 10,000 \times (1 + 0.07)^{30} = 76,123Your initial $10,000 grows to over $76,000 without additional contributions.
Investment Options in the Amentum 401(k)
Most 401(k) plans offer a mix of:
- Stock Funds – Higher growth potential but more volatile.
- Bond Funds – Lower risk, steady income.
- Target-Date Funds – Automatically adjust risk as you near retirement.
- Money Market Funds – Low-risk, low-return.
Comparing Investment Choices
| Fund Type | Risk Level | Avg. Return (Historical) | Best For |
|---|---|---|---|
| Large-Cap Stocks | High | 10% | Long-term growth |
| Bonds | Low | 4-6% | Stability |
| Target-Date 2050 | Medium | 7-9% | Hands-off investors |
Employer Matching: Free Money You Shouldn’t Miss
If Amentum offers a match, not contributing enough to get the full match is like leaving free money on the table. Suppose the match is 50% up to 6% of salary:
- Scenario: You earn $70,000 and contribute 3% ($2,100). Amentum adds $1,050.
- Optimal: Contribute 6% ($4,200) to get the full $2,100 match.
Tax Benefits of the Amentum 401(k)
- Tax-Deferred Growth – No capital gains taxes on earnings until withdrawal.
- Lower Taxable Income – Contributions reduce your taxable income now.
- Roth Option (if available) – Pay taxes now, withdraw tax-free in retirement.
Traditional vs. Roth 401(k)
| Feature | Traditional 401(k) | Roth 401(k) |
|---|---|---|
| Tax Treatment | Pre-tax contributions | After-tax contributions |
| Withdrawals | Taxed as income | Tax-free |
| Best For | High earners now | Those expecting higher taxes later |
Withdrawal Rules and Penalties
- 59½ Rule – Withdrawals before 59½ incur a 10% penalty plus income taxes.
- Required Minimum Distributions (RMDs) – Start at age 73 (under SECURE Act 2.0).
Strategies to Maximize Your Amentum 401(k)
- Contribute Enough to Get the Full Match – It’s an instant return on investment.

- Rebalance Annually – Adjust allocations to maintain risk tolerance.
Common Mistakes to Avoid
