2024 401k Contributions Max. The contribution limit for simple 401 (k)s is $16,000 (up to $19,500 if you're 50 or older). Some retirement plans have lower limits, so.
For those with a 401 (k), 403 (b), or 457 plan through an employer, your new maximum contribution limit will go up to $23,000 in 2024. What does it mean to max out your 401(k) in 2024?
