How do I maximize my employer 401(k) match?

Many employees are not taking full advantage of their employer's matching contributions. If, for example, your contribution percentage is so high that you obtain the $18,500 (year 2018) limit or $24,500 (year 2018) limit for those 50 years or older in the first few months of the year then you have probably maximized your contribution but minimized your employer's matching contribution.
