So much has changed for 2018 I don't think they are geared up to make that calculation. Taxcaster does not cover it IMHO.
See this article for brackets. It says the rates are no longer tied to your income bracket. Not sure I understand that..if they mean the dollar ranges are only for LT capital gains or not. https://www.marketwatch.com/story/your-simple-guide-to-the-new-capital-gains-tax-rates-2018-04-16
Remember to calculate only on your gain not the total proceeds of the sale.
