Frequently Asked Questions

What is a 401(k)?

A 401(k) is a retirement savings plan sponsored by employers:

  • Contributions are deducted directly from your paycheck
  • Traditional 401(k) contributions are pre-tax, reducing your taxable income
  • Roth 401(k) contributions are after-tax but grow tax-free
  • Many employers offer matching contributions as part of your benefits
  • Funds typically cannot be withdrawn before age 59.5 without penalties
How does employer matching work?

Employer matching is essentially free money for your retirement:

  • Common match: 50% of contributions up to 6% of salary
  • Example: If you earn $75,000 and contribute 6% ($4,500), employer adds $2,250
  • Always contribute at least enough to get the full employer match
  • Match formulas vary by company - check your benefits package
  • Some employers have vesting schedules for matching contributions
What are the 401(k) contribution limits?

The IRS sets annual limits on 401(k) contributions:

  • 2024 employee contribution limit: $23,000
  • Catch-up contribution (age 50+): Additional $7,500
  • Total limit (employee + employer): $69,000 or 100% of compensation
  • Limits are adjusted annually for inflation
  • These limits apply across all your 401(k) accounts combined
When should I start saving for retirement?

The best time to start saving is as early as possible:

  • Compound interest works best over longer time periods
  • Starting at 25 vs 35 can result in significantly more savings
  • Even small contributions early on can grow substantially
  • Don't miss out on employer matching - it's a 50-100% instant return
  • If you haven't started yet, start now - every year counts
