If you want to post a particular FireCalc scenario, you can post a url that contains
precisely all the parameters you entered.
If your browser is IE, on the results page, right click on "Link To This Set Of Data", then click on "Copy Shortcut", the paste it into a post.
If your browser is Chrome, on the results page, right click on "Link To This Set Of Data", then click on "Copy Link Address", then paste it into a post.
If you are using a different browser, do whatever works for that browser.
Here is what the default FireCalc results url looks like:
FIRECalc: A different kind of retirement calculator
Yeah, I know it is a mess (that you can't necessarily see in a post because of how the software handles it), but it contains exactly every parameter entered.
