Understanding Compound Interest
Compound interest is the interest calculated on both the initial principal and the accumulated interest from previous periods. Albert Einstein allegedly called it "the eighth wonder of the world," and for good reason—it's one of the most powerful forces in finance.
The formula: A = P(1 + r/n)^(nt)
- A = Final amount
- P = Principal (initial investment)
- r = Annual interest rate (decimal)
- n = Number of times interest is compounded per year
- t = Number of years
Key takeaway: The more frequently interest is compounded and the longer your investment period, the more your money will grow. Regular contributions amplify this effect significantly.
