My goal is to max out my 401k -> Roth IRA rollover. My compensation comes in the form of salary + bonus + stock and contributions to 401K must come out of salary/bonus. In order to make this happen I've sold a chunk of my stock to supplement my monthly income so that I can contribute enough to max out my 401k. Hopefully this makes sense, happy to clarify.
I sold all the stock I would need for the year at once (to minimize short term capitol gains, taxes were paid on them already when they were vested) so I have a chunk of cash (~$7000) that more than covers the difference in take home pay from contributing a large part of my paycheck to this rollover operation. In essence I'll be paying myself an extra $1000 a month out of this cash until the end of the year to make up the contributed salary income.
That means that the final $1000 for December is just sitting in my savings account for 7 months instead of working for me (or the $1000 for November is sitting around for 6 months, etc.). What is the best way to get the maximum returns on this money, while still making it easy to withdraw a fixed amount every month? I could just keep it simple and leave it in my savings account but this feels non-optimal. Any other ideas? Could I have performed any part of this operation in a more efficient way?
Thanks for any and all input!
