EV Calculator

Welcome to the beginnings of our EV Calculator. First off I want to thank Uve and Hemp for their respective calculators, which I've been using for years and have based this tool off of.

The goal with this project is to create an calculator that provides a high level overview for what-if analysis, but still make it easy to see all of the detailed information. Clicking any of the detail trigger icons will open a section to show more detail.

This tool is still under development and there will certainly be bugs. For example it my not work with Internet Explorer, I'd recommend getting the latest copy of Firefox.
