The Rule of 72 is one of the simplest tools every young investor should know. If you want to understand how fast your money can grow, just divide 72 by your annual return.
That number tells you how many years it takes for your investment to double.
It’s more than a math trick… it shows the power of compound growth, the idea that your money works for you even while you sleep.
Master this rule early, and you’ll start seeing investing as a long-term game.
