What is Compound Interest
Compound interest means you earn interest not just on your original money, but also on the interest you already earned.
It’s like earning interest on your interest — and it keeps building up over time! Compound interest works best when you give it a lot of time — it’s slow at first, but amazing later.
How to calculate compound interest with examples 🔢:
A = P x (1 + r / n)^n x t
Where:
-
A = Final amount (including interest)
-
P = Principal (the starting amount you invest or save)
-
r = Annual interest rate (as a decimal — e.g., 5% = 0.05)
-
n = Number of times interest is compounded per year (e.g., monthly = 12)
-
t = Time in years
Real-World Examples:
-
Savings accounts: some banks pay interest on your savings, and that interest earns more interest over time.
-
Investing in stocks: when you reinvest your dividends, your earnings buy more stocks, which then make even more money — that's compound growth in action!
Why is Compound Interest Important?
-
It grows your money faster the longer you leave it alone.
-
Time is your best friend — the earlier you start, the more powerful it becomes.
-
Small amounts can turn into big amounts if you’re patient!
