📘 What Is Compound Interest?
Compound interest : It is the interest calculated not only on the initial principal but also on the accumulated interest from previous periods.
In simple terms, it's "interest on interest."
Let’s break it down with an example.
🔍 Simple Interest vs Compound Interest
- Simple Interest: You earn interest only on your original amount.
- Compound Interest: You earn interest on your original amount and; the interest that amount has already earned.
For example:
- You invest $1,000 at a 5% interest rate.
- After one year: You earn $50.
- In simple interest, you continue earning $50 every year.
- In compound interest, your second year is calculated on $1,050 — so you earn $52.50, and so on.
Over time, that difference becomes huge.
🧮 The Compound Interest Formula
Here’s the mathematical formula used to calculate compound interest:
A = P (1 + r/n)^(nt)
Where:
- A = Final amount (after interest)
- P = Initial principal balance
- r = Annual interest rate (decimal)
- n = Number of times interest applied per year
- t = Number of years the money is invested or borrowed
This formula might look intimidating, but don’t worry — that's why we’ve included a

💡 Why Compound Interest Is So Powerful
1. Time Is Your Best Friend
The earlier you start, the more time compound interest has to work its magic. Even small amounts can grow into large sums over decades.
2. It Rewards Patience
The longer you stay invested, the more exponential the growth. That’s why most financial advisors recommend long-term investing over short-term trading.
3. It Builds Wealth Automatically
You don’t need to be rich to benefit from compound interest. All it takes is consistency and time.
🧓 How Compound Interest Helps in Retirement
In the U.S., retirement savings like ' 401(k)s ', 'Roth IRAs', and 'Traditional IRAs' benefit immensely from compound interest.
Let’s say you contribute $300/month to your 401(k) with a 6% return starting at age 25.
- By age 65, you could have over '$600,000+' saved!
- Wait until 35 to start? You might only have '$300,000'.
That 10-year head start makes a massive difference.
