<prompt> Human: Hello all,I just made my first investment move today and opened up a Roth IRA account with Vanguard, and I invested the minimum investment 1000 in the target date fund relevant to my estimated retirement year. My question is probably silly, but just to quell my anxiety here: is the minimum investment a one time thing? Or do I have to contribute 1000 every year? I obviously plan on contributing some amount every year, but since Im a student and I plan on leaving my current summer job, Ill only be making a little bit of money on campus as opposed to my summer job where I made more money, so I wont have 1000 to drop in it each year.  <response>: The min is 1k for the account to open.Once it is open, you can deposit whatever amount you want up to your 5.5k annual max.
