About This Scenario
The 2026 401(k) contribution limit is $23,000/year ($1,917/month). If you max out your 401(k) for 30 years at 8% returns, you'd accumulate about $2.87 million. With an employer match of 50% up to 6% of salary (on a $100K salary), that's an additional $250/month of free money — adding roughly $375,000 more over 30 years. Always contribute at least enough to get your full employer match.
