About 401(k) Plans

A 401(k) is an employer-sponsored retirement savings plan that allows employees to contribute a portion of their salary to individual accounts. Many employers offer matching contributions, which is essentially free money for your retirement.

Example Calculation:

For a 30-year-old with a $60,000 salary contributing 6% with a 3% employer match:

Annual employee contribution: $3,600

Annual employer match: $1,800

Total annual contribution: $5,400

After 35 years at 7% return: ~$1.24 million

Key features of 401(k) plans:

  1. Tax Advantages: Traditional 401(k) contributions are pre-tax, reducing your current taxable income
  2. Employer Matching: Many employers match a portion of your contributions
  3. Higher Contribution Limits: Much higher than IRA limits ($22,500 in 2023, plus $7,500 catch-up if 50+)
  4. Automatic Payroll Deductions: Makes consistent saving easier
  5. Investment Options: Typically offer a range of investment choices

401(k) Contribution Strategies

• Contribute enough to get the full employer match: This is free money you shouldn't leave on the table

• Aim for 10-15% of your income: Including employer match, try to save 10-15% of your salary for retirement

• Increase contributions gradually: Increase your contribution rate by 1% each year until you reach your target

• Take advantage of catch-up contributions: If you're 50 or older, you can contribute additional funds

• Consider Roth 401(k) options: If available, Roth contributions are made with after-tax dollars but grow tax-free

Understanding these strategies can help you maximize your 401(k) benefits and build a substantial retirement nest egg.

401(k) Calculation Formulas

Annual Contribution:

Employee Contribution = Salary × Contribution %
Employer Match = Salary × min(Contribution %, Match Limit %) × Match %
Total Contribution = Employee + Employer Contributions

Future Value of Contributions:

FV = PV(1+r)^n + C[((1+r)^n - 1)/r]

Where:
FV = Future Value
PV = Present Value (current balance)
r = Annual return rate
n = Number of years
C = Annual contribution
