Those are all great resources, but I would also try to find your state's site. Usually you can pretty easily find your state's official ACA site without much difficulty using a search engine, and most states have calculators that you don't need to log into. One other thing - I was initially confused by the differences between premium tax credits and cost sharing reductions. By playing around with different income levels I was able to see how big a difference they make and where each one kicks in. I was able to see that by increasing my income from Roth Conversions by $8,000 / year I was likely to add $6,000 in health care costs and taxes. Taking $8k each year from my 'stache to get an extra $2k to spend was not a tradeoff I wanted to make, and the calculators helped me to understand those impacts. If you have an ability to generate a specific income each year (like if you're doing a Roth ladder) then it really pays to try different income levels. I would recommend looking at numbers just above and below 150% of the Federal Poverty Level, 200%, and 250%. When you do this, be sure to look not only at premiums but also at things like out of pocket maximums. Keep in mind that (I think) the Cost Sharing Reductions apply only to Silver plans. If you're able to generate a low income (like 150% of the FPL) then a silver plan may be much less expensive than a bronze plan.
