What is Compound Interest?

Compound interest is the interest calculated on the initial principal and the accumulated interest from previous periods. In simple terms, it’s “interest on interest,” which can make a significant difference in your savings or investments over time.

How Does Compound Interest Work?

When you invest money or save it in an interest-bearing account, you earn interest on your principal amount. With compound interest, you also earn interest on the interest you’ve already earned. This creates a snowball effect, potentially leading to exponential growth of your money over time.

The formula for compound interest is:

A = P(1 + r/n)^(nt)

Where:

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

Benefits of Compound Interest

1. Accelerated Growth: Your money grows faster compared to simple interest.
2. Time is Your Ally: The longer you leave your money to compound, the more it grows.
3. Passive Income: Once set up, your money works for you without additional effort.

Factors Affecting Compound Interest

1. Interest Rate: Higher rates lead to faster growth.
2. Compounding Frequency: More frequent compounding (e.g., daily vs. annually) results in higher returns.
3. Time: The longer the investment period, the more dramatic the effects of compounding.
4. Initial Investment: A larger principal amount will yield more significant results.
5. Regular Contributions: Adding money regularly can substantially boost your returns.
