The 4% Safe Withdrawal Rule
Financial planners use the Trinity Study 4% rule: withdrawing 4% of your total retirement nest egg in your first year of retirement (adjusted for inflation) offers a 95% probability of never running out of money over 30 years.
Traditional vs Roth 401(k)
Traditional 401(k) contributions are pre-tax (reducing your paycheck tax today), while withdrawals in retirement are taxed. Roth 401(k) contributions are post-tax, but all qualified growth and retirement withdrawals are 100% tax-free.
Vesting Schedules
Your own contributions are always 100% yours. However, employer matching funds often follow a 3-year cliff or 5-year graded vesting schedule before you can take the company money if you change jobs.
