Understanding Compound Interest

Compound interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods. This creates a snowball effect where your investment grows exponentially over time.

The formula used is: A = P(1 + r/n)^(nt), where:

• A = Final amount
• P = Principal (initial investment)
• r = Annual interest rate (decimal)
• n = Number of times interest is compounded per year
• t = Time in years

Compounding Frequency Impact

The frequency of compounding significantly affects your returns. More frequent compounding means interest is calculated and added to your principal more often, leading to higher overall returns. Daily compounding typically yields the best results, followed by monthly, quarterly, and annually.
