Very cool! I love it! A couple small things: * hitting the backspace key while editing any of the numbers seems to clear the entire box * a cool expansion on this project would be to allow one input to be a variable - e.g. my current contribution rate, and draw some graphs showing how the value of that variable effects the the numbers in retirement - e.g. when I will run out of money. * if you're looking for more audiences, /r/personalfinance and /r/financialindependence would love this.
