<prompt> Human: I recently graduated from college, and I am now employed full-time. Today I found out I can enroll in my companys 401k plan which has a 100 match of up to 3, but I cannot get that match until after I have been working at the company for 6 years. My company also has a profit-sharing program, but there is no information on it. I have to determine how much per paycheck I want to contribute and if I want to make aggressive or conservative investments by next WEEK! I took several economics courses in college, and none of them talked about 401ks. I should mention I have the option of deferring my payments through pre-tax 401k or a Roth 401k, and I do know the difference between them. What is a good ballpark percent to contribute per paycheck? Which type of 401k is better for someone who is starting to save for retirement early?  <response>: Minimum amount? Enough to get the full matchingGood amount? 10Great amount? 15Amazing amount? 20Best amount? Whatever ensures you max out your allowable contributions currently, 18,500 for 2018.
