A 401(k) match is an employee benefit that allows an employer to contribute a certain amount to their employee’s 401(k) plan. The match can be based on a percentage of the employee’s contribution, up to a certain portion of their total salary or a set dollar amount, depending on the terms of the plan. Not all employers offer this benefit, and some have prerequisites for participating in the match, such as a minimum required contribution or a cap up to a certain amount.
