401k limits are about $58k per year... You can only personally contribute up to about $20k per year. There are ways to take advantage of the difference such as employer matching and after-tax traditional 401ks (and instantly convert to Roth money). This is also a way of contributing to a Roth (IRA?) if you don't qualify for a regular Roth IRA (make too much money) or want to contribute more than the $6k limit per year.
