Tips
Maximize Your Employer Match First
Always contribute at least enough to capture the full employer match. Leaving match money on the table is equivalent to declining part of your compensation.
Increase Contributions with Each Raise
Commit to increasing your contribution percentage by 1% each time you get a raise. You will not feel the difference in take-home pay, but the long-term growth is substantial.
Know the 2025 Contribution Limits
For 2025, the employee contribution limit is $23,500, with a $7,500 catch-up for ages 50 and older. Plan your percentage so you do not accidentally exceed the cap mid-year.
Account for Vesting Schedules
Your employer match may vest over 3 to 6 years. Factor in your vesting schedule when calculating how much of the employer contribution you can actually keep if you change jobs.
Frequently Asked Questions
How much can I contribute to my 401(k)?
For 2024, the maximum employee contribution is $23,000, with an additional $7,500 catch-up contribution for those 50 and older. Employer matching contributions do not count toward the employee limit but are subject to the overall $69,000 combined limit.
Should I contribute to a Traditional or Roth 401(k)?
Choose Traditional if you expect to be in a lower tax bracket in retirement — contributions reduce taxable income now. Choose Roth if you expect higher taxes in retirement — contributions are after-tax but withdrawals are tax-free. Many people benefit from having both.
What happens to my 401(k) if I leave my job?
You have several options: leave it with your former employer, roll it into your new employer 401(k), roll it into an IRA, or cash it out (not recommended due to taxes and penalties). A direct rollover to an IRA gives you the most investment options.
