<prompt> Human: I am 26 yo, living in a double income household. My spouse and I make about 65k each. I got my current job around April and put my contribution at 15 and now I am looking at maxing out my Roth 401k. At this rate, even contributing 100 of my paycheck would come under the IRS limit of 18,500. Should I just go ahead and put all 100 into that? We have no debt besides mortgage and have an emergency fund of 3-6 months. We have pretty good savings that we really wouldnt need my income for the rest of the year I hope. Also, my husband is already putting in 40 of his paycheck into his 401k.  <response>: You cannot contribute 100 of a paycheck; medicare and social security deductions must come out regardless. You would be able to contribute the remaining 92 or whatever percent, if your plan allows it. Plans will sometimes cap your contributions at whatever they feel like 92, 70, 50, whatever.If your budget is looking good and you dont have any future expenses you need to save up for then aggressively contributing is a good choice
