How It Works
The 2025 401k contribution limit is $23,000 ($30,500 if age 50+). Employer matches are essentially free money — if your employer matches 50% up to 6% of salary, contributing at least 6% gives you a 50% instant return on that money. Pre-tax contributions also reduce your current tax bill. At a 22% marginal rate, every $1,000 contributed saves $220 in taxes.
