RULE OF "72" I've always found the concept of compound interest fascinating! The Rule of "72" basically calculates that your money will "double" at an exact point by dividing 72 by the % of interest! 72 - 1% interest = 72 years* 72 - 3% interest = 24 years 72 - 6% interest = 12 years 72- 9% interest = 8 years 72- 12% interest = 6 years 72 - 15% interest = 4 years, 10 months * If you had invested $1,000 and received 1% interest, it would have grown to $2,000 in exactly 72 years. This is especially important (6 comments)
