<prompt> Human: This is my first career and I understand after reading the Wiki that the Roth IRA limits the amount you can put in each year to 5,500. But my company has stated that they will match 50 of my contributions up to the max that I contribute 18,000. Heres an email in response to the question I asked:Hello sendmeHaikus,Thanks for reaching ___.For calendar year 2017, the combined limit for pre-tax andor Roth contributions to the 401k Plan is 18,000. Therefore, you can contribute: 18,000 pre-tax OR 18,000 Roth OR 18,000 combined pre-tax and Roth. Edit: Thanks everyone! Turns out, yeah, I was confusing Roth IRA and Roth 401k.  <response>: Looks like your plan offers a Traditional 401k and a Roth 401k option. You can put up to 18,000 split between them any way you desire. The 5,500 limit is a Roth IRA, which is something different.Bottom line is you should invest as much as you can to maximize the employer contribution... If theyre really going to match 50 of your contributions with no limit, theyll give you a free 9,000 every year if you max it out. Not a bad deal!
