Lunch Savings Calculator

As I sit here eating my cheap "brown bag" lunch here as always at work (Yeah Right!), I thought I would calculate the small fortune I have amassed by eating like this. The default investment return is a reasonable 5.0% (although you can try 10.5%, the 70 year average for the S&P 500). You can even increase the return up to 50% for fun.

Have fun!
