here’s another angle to look at it. The assumptions are that you are closer to retirement than aren’t and that you have participated in the 401k plan for many many years (20, 25, 30?). In other words you already have a sizable 401K balance. If that’s the case and if I were you, just kick it and enjoy the “windfall”. At this point in your life, the yearly addition to the plan is really negligible. The only reason why people want to continue to sock it away is because a) they can b) get the matching c) tax break. Since none of these applies to you there’s no need to worry about it. Splurge a little bit. Surprise your SO with a nice vacation or some fancy stuff.
