So say we need $70k a year to cover our all of our expenses (including paying for healthcare), we pull that from the brokerage, and let's say half of that is gains ($35k). If I said our income was $100k a year, we could do a Roth conversion for $92.7k ($100k income - $35k in LTCG + $27.7k standard deduction), and still get that $5,400/yr. subsidy, right?

Am I on the right path here, or am I completely off-base? I'm sure there's a calculator out there to run through these scenarios, it's just far enough away for me that I haven't bothered looking for it yet.
