By the rule of 70, if one invests $3000 in a bank account and earns 2% real annual return on average, then it would take 35 years (702) until it is worth $6,000. This $6,000 would take another 35 years (702) to double up to $12,000 by the rule of 70. Therefore, $3,000 would take 70 years (35+35) until it was worth $12,000.
