Understanding Compound Interest and Savings Growth
Compound interest is often called the "eighth wonder of the world" because of its incredible power to grow wealth over time. Understanding how it works can help you make informed decisions about saving and investing.
The Power of Compound Interest
💰 What is Compound Interest?
Interest earned on both the initial principal and the accumulated interest from previous periods
Also known as "interest on interest"
Grows exponentially over time
More powerful than simple interest
Foundation of wealth building
⏰ Time is Your Greatest Ally
The longer your money compounds, the greater the growth
Starting early maximizes compound interest benefits
Even small amounts grow significantly over decades
Regular contributions accelerate growth
Patience is key to building wealth
📈 The Rule of 72
Approximate time for investment to double
Divide 72 by annual interest rate
