True! That number is, at best, a lower bound. Interest rates will likely make it MUCH larger, even with an inflation factored in. However, I've no way to calculate that as I don't have a crystal ball.

Good catch on the tuition! I did subtract it but did not mention it as I thought it would not read as well. In the end, the price of the lotto ticket should be MUCH higher when compound interest is factored in. How much is anyone's guess.
