“Compound interest is the eighth wonder of the world. He who understands it, earns it … he who doesn’t … pays it.” – Albert Einstein
The word percentage comes from the french words “pour cent” which mean “for one hundred” (or their latin equivalents)
A percentage sign is derived from the numerals 100, with the 1 sanwiched in-between the two 0′s (%). This is like how our uppercase A originally represented the head of a ram.
If you invested $20 for just 30% annual return, compounded monthly, in 40 years you would have just over $60,000,000
