Hi HN,<p>I just finished a major refactor of a tool I made (and shared here) some time ago!<p>Feel free to give it a try: <a href="https://www.rebalancecalc.com/" rel="nofollow">https://www.rebalancecalc.com/</a><p>## What this is:<p>This tool helps you align investments (across multiple accounts) to a target asset allocation. The tool takes U.S. taxes into consideration, and automatically suggests the types of trades you'd make to stay in line with your target asset allocation.<p>The "about" button on the website provides a good summary, and the "how it works" button outlines the exact procedure this tool uses.<p>## Why I'm sharing this:<p>With tax season nearing (a good time to think about re-balancing your long-term investments), and this new UI finally in a state I'm comfortable sharing, I felt it would be worthwhile to share this project again.<p>Any feedback is very appreciated!<p>## Important consideration:<p>This tool is definitely best used on a computer, the UI can get quite overwhelming on mobile (though it does work on mobile).
