Question: what is the maximum one can contribute to 401k?
Answer: First things first: In 2020, the most you can contribute to a 401(k) is $19,500 (up from $19,000 in 2019); that limit increases to $26,000 (up from $25,000 last year) if you're 50 or older. Employer contributions are on top of that limit. These limits are set by the IRS and subject to adjustment each year.
