How Principal Financial Group 401k Works
1. Employer Setup

- Contribution rules

- Investment choices available to employees
2. Employee Enrollment
Employees enroll through an online portal and choose:
- Contribution percentage

Types of Contributions in Principal 401k
Employee Contributions
Employees choose how much of their salary to contribute.
Example:
- Monthly salary: $4,000
- Contribution rate: 6%
- Monthly contribution:
$4,000 × 6% = $240
Annual contribution:
$240 × 12 = $2,880
Employer Matching Contributions
Many employers match employee contributions up to a certain percentage.
Example:
- Employer match: 50% of employee contribution up to 6%
- Employee contributes: $2,880 per year
- Employer match: 50% of $2,880 = $1,440
Total yearly investment:
$2,880 + $1,440 = $4,320

Target-Date Fund Example
If an employee plans to retire in 2050, they may choose a 2050 Target-Date Fund. The fund automatically adjusts risk as retirement approaches.
Understanding Fees in Principal Financial Group 401k
Fees play a major role in long-term retirement savings. Even small percentages can significantly reduce final returns.

Fee Impact Calculation (Dollar Example)
Let’s understand how fees affect savings.
Scenario Without Fees
- Initial investment: $50,000
- Annual return: 7%
- Time period: 30 years
Future value without fees ≈ $381,000
Scenario With 1.25% Annual Fees
- Net return: 7% – 1.25% = 5.75%
Future value ≈ $267,000
Difference Due to Fees
$381,000 – $267,000 = $114,000 lost to fees
👉 This shows why understanding 401k fees is extremely important.
