🌟 Compound Interest – The 8th Wonder of the World

🧠 Introduction

Albert Einstein once said, “Compound interest is the 8th wonder of the world. He who understands it, earns it; he who doesn’t, pays it.”
This single line perfectly describes the secret behind wealth creation. Whether it’s saving, investing, or building a business, compound interest is the ultimate growth engine.

💡 What Is Compound Interest?

Compound interest means earning interest on both your original investment and the interest that has already been added to it.
Unlike simple interest, which pays you only on your initial money, compound interest keeps multiplying your returns over time.

Formula:

$$A = P(1 + \frac{r}{n})^{nt}$$

Where:

• A = Final amount

• P = Principal (starting amount)

• r = Annual interest rate

• n = Number of times interest compounds in a year

• t = Time in years

📈 Example of Power of Compounding

Suppose you invest ₹10,000 at an annual interest rate of 10% compounded yearly for 10 years:

$$A = 10,000 (1 + 0.10)^{10} = ₹25,937$$

✅ Your profit = ₹15,937 — all earned automatically through compounding.

🕒 The Magic of Time

The earlier you start, the more you earn. Compounding rewards patience.

Time (Years)	₹10,000 @10% grows to	Total Profit
5 years	₹16,105	₹6,105
10 years	₹25,937	₹15,937
20 years	₹67,275	₹57,275
30 years	₹1,74,494	₹1,64,494

Imagine if you kept investing every month — the results would be massive!

💰 Real Smart Earning Example

If you invest just ₹100/day (₹3,000/month) at 12% annual return:

Duration	Final Amount
10 Years	₹6.9 Lakh
20 Years	₹24 Lakh
30 Years	₹85 Lakh

That’s the real power of compounding — small, consistent efforts turn into big results.
