📌 5 Tips to Maximize Your 401k Match
- ✓ Always capture the full match first. An employer match is a 50-100% instant return on your contribution — no other investment beats that. Contribute at least enough to get every dollar.
- ✓ Read your Summary Plan Description (SPD). The match formula, vesting schedule, and eligibility rules are spelled out in plain English. Look for "cliff vesting" (0% → 100% on a specific date) vs "graded vesting" (20% per year).
- ✓ Increase contributions with every raise. A 3% annual raise lets you boost your 401k by 1% with no impact on take-home pay (the 1% raise covers the 1% retirement boost in most tax brackets).
- ✓ Don't stop at the match — go to 15%+. The match is floor, not ceiling. Financial planners recommend contributing 15-20% of salary (including employer match) for a comfortable retirement.
- ✓ Know the vesting schedule before you job-hop. If you're 2 years into a 4-year graded schedule, leaving forfeits 50% of the match. The math can favor staying until the cliff if the match is large.
