GMAT Tip: Americans Protest Iran Nuclear Testing

No, this isn’t a political post, as this isn’t a world affairs blog.  It’s just a mnemonic device to memorize the compound interest formula.  One of my friends told me this is how he remembered it for the GMAT.  You can just memorize this one, as replacing “1” for the “n” value (number of periods) will give you the simple interest formula.  The “I” in Iran stands for the number 1.

  • P = principal amount (initial investment)
  • r = annual nominal interest rate (as a decimal)
  • n = number of times the interest is compounded per year
  • t = number of years
  • A = amount after time t

    •  

    Do you have another mnemoic device for this formula?  (Maybe one less political?)
