Nice tool, but a lot of the market is being altered in a way that blows out these savings. For example, I run my business and my overall tax rate last year was 28%. However, when I account for healthcare premiums and hitting my out of pocket max, I was over 40%. According to the calculator, my tax burden is reduced slightly under the plan. That said, my health costs for next year went up 37% and I'm receiving worse coverage. As such, I will be at a net loss for 2018 and it looks like it will become worse in 2019 if the individual mandate is eliminated.<p>So, no, I don't expect a calculator to be perfect, but I can't help but stress how important the changes in healthcare costs for self-employed are under this plan.
