Bees, Thanks for the reply. To be honest, I don't need a final value as these are just estimated taxes. Final reckoning will be when I file my 2018 return next April.
But to answer your question, "..rates are no longer tied to your income bracket". This only applies to Long Term gains. Short Term gains are still treated as ordinary income from a bracket perspective, just like a W2 job.
But this isn't my question, as my stock sales are all from short term gains.
