The NUMBERS are right. 8% seems a bit high if you are not counting INFLATION which usually runs at an average of about 3%.

Over a 10 year time horizon, they will not look too different. After 30 years, it can add up to be a noticeable difference.

Am I doing this math correctly?
And is 8% a reasonable assumption in MMM land?

Do you have a separate number for inflation, or is your 7% supposed to be real?I'd probably use closer to 4-5% real, 7-8% nominal, personally, but it all depends on your crystal ball, as we're all just guessing here.
