Found a mistake in the math? Have a case the calculator can't model? Want to say it helped? Email works best.
A few things worth knowing before you write:
- I can't give financial or legal advice about your situation, and I won't try. I can tell you what the calculator is doing and why.
- If you think a number is wrong, include the assumptions you set. The fastest way is a screenshot of the left-hand column.
- Reports of actual bugs get fixed. Suggestions get read, and the good ones get built.
I'm one person doing this in spare time, so replies can take a few days.
