Balance after t years (A) = P * (1 + r/n)^(n*t)
Total interest earned = P * (1 + r/n)^(n*t) - P
Total growth factor = (1 + r/n)^(n*t)
Interest rate per compounding period = r/n
Total number of compounding periods = n*t
Effective annual rate (APY) = (1 + r/n)^n - 1
Years for the investment to double = log(2) / (n * log(1 + r/n))
