Terms of use

The Roth Conversion Calculator and its MCP server for AI assistants are free to use, provided by me, Mario (Kind of Lost), as they are, without warranty of any kind.

• Not tax, legal or financial advice, and I'm not a CPA. Results are optimal only for the assumptions you enter (the real return, the tax rate on what is left, and the other inputs) and use 2026 US federal tax law held constant; they do not predict the future or changes in the law. Check the plan with a qualified professional before you act on it.
• The model leaves things out (for example pensions with survivor options, a spouse of a different age, charitable gifts, and the ACA premium credit, IRMAA and NIIT unless switched on).
• Do not use the tool to overload the server or to run automated bulk jobs; runs are rate limited.
• I may change, limit or discontinue the tools at any time.
• To the extent the law allows, I am not liable for any loss arising from using them.
