🚀 How Compounding Works (With Real Examples)
Compounding is one of the most powerful concepts in finance, yet many people underestimate it.
It’s the simple idea that allows your money to grow exponentially, not linearly.
Albert Einstein famously called compounding the 8th wonder of the world.
Let’s understand how compounding actually works, with real and easy examples.
🔄 What Is Compounding?
Compounding means earning returns on both your original investment and the returns generated earlier.
In simple words:
Your money starts earning money, and that money also starts earning money.
This creates a snowball effect over time.
🧮 Simple Compounding Example (Yearly)
Suppose you invest ₹1,00,000 at 10% annual return.
| Year | Amount at Start | Return | Total Amount |
|---|---|---|---|
| 1 | ₹1,00,000 | ₹10,000 | ₹1,10,000 |
| 2 | ₹1,10,000 | ₹11,000 | ₹1,21,000 |
| 3 | ₹1,21,000 | ₹12,100 | ₹1,33,100 |
Notice:
-
Returns increase every year
-
You earn interest on interest
That’s compounding.
📈 Real SIP Compounding Example (Monthly Investment)
Let’s take a realistic SIP example.
📌 Scenario
-
Monthly investment: ₹5,000
-
Duration: 20 years
-
Expected return: 12% per year
📊 Result
-
Total Invested: ₹12,00,000
-
Final Value: ₹49,90,000 (approx)
-
Wealth Gained: ₹37,90,000
👉 More than 4× growth, mainly due to compounding.
You can calculate this instantly using the ToolNest SIP Calculator.
⏳ Why Time Is the Biggest Factor in Compounding
Let’s compare two investors:
👤 Investor A
-
Invests ₹5,000/month for 10 years
👤 Investor B
-
Invests ₹5,000/month for 20 years
| Duration | Total Invested | Final Value |
|---|---|---|
| 10 Years | ₹6,00,000 | ₹11.6 Lakhs |
| 20 Years | ₹12,00,000 | ₹49.9 Lakhs |
👉 Double the time → 4× wealth
Time matters more than amount.
