Suntrust sent me an interesting flyer. I'm new to the technical part of investing even though I've been dumping $$$ into TSP for over 3 years. Are we getting compound interest with TSP?

The returns are almost unbelievable:

Hello Hybrid -

TSP is part of the miracle of compound interest.

Albert Einstein suggested that compound interest was one of the most powerful forces in the universe (http://www.ruleof72.net/rule-of-72-einstein.asp).
