Question: what is the maximum percentage you can contribute to a 401k?
Answer: The 401(k) also has an annual total contribution limit, which caps the combined amount you and your employer can contribute. In 2020, your total 401(k) contributions — from yourself and your employer — cannot exceed $57,000 or 100% of your compensation, whichever is less. That limit rose from $56,000 in 2019.
