Thanks for your consideration.
+1 on keeping the current version intact until there is confidence in any new version.
As far as testing to gain confidence, here's a suggestion: Allow the option of accepting inputs from a plain text/csv file. This would let testers create a suite of standard inputs (or ad hoc as desired), and easily run them to test the output against an expected result. And if the output could be dumped to a text/csv file, an entire suite of tests could be automatically validated. That's a heck of a lot easier and error free than typing stuff into fields on a web page. And easy to share compared to saving a bunch of profiles/cases under a user name.

Absolutely. And if you were to tell us you just can't support this, because there just is no money in it for you, I'd respect this. It's a business, not a charity.
I do hope you can find ways to profit from it. I know next to nothing about making money from services like this, so I have nothing to offer there. But even a cheapskate like me would be willing to pay something ($10/year is a nice round, picked out of the air number) for something above a very basic set of features. I think if you limit a 'pro' version to only very advanced features, the audience would also be very small. Maybe you'd need to go very advanced, and attract financial planners/pros - a much smaller audience, but maybe willing to pay much bigger bucks? But again, I know nothing in this area.
What about an open source approach? Again, I have no idea how these are managed, but there seem to be a lot of interested coders out there, and I've learned that there are some free libraries out there that seem to be easy to use that provide some very fancy and useful graphing options.
