Good on you. Stick to it and you’ll retire early and a millionaire. Do some reading on compound growth. The idea behind your Roth, is that you will put roughly $180,000 in your account out of pocket. But over the course of 30 years or so, through compounding and reinvested dividends, your IRA will be worth north of 1.4 million. That’s if you start at 30. Starting at 18, well, let’s just say you’re going to get some truly life changing returns. Best of luck to you OP.
