📈 The Eighth Wonder of the World: Compound Interest
Albert Einstein famously called compound interest "the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it."
When investing in index funds, mutual funds, or ETFs, a Systematic Investment Plan (SIP) allows you to dollar-cost average into the market automatically every month.
🧮 The SIP Mathematical Formula
The future value of a periodic monthly investment is calculated using:
$$M = P \times \frac{(1 + i)^n - 1}{i} \times (1 + i)$$
Where:
- $M$ = Total Maturity Amount
- $P$ = Monthly Investment Amount
- $i$ = Periodic Interest Rate ($\frac{\text{Annual Rate}}{12 \times 100}$)
- $n$ = Total Number of Months
📊 Real-World Scenario: What Happens Over 20 Years?
If you invest $500 every month at an average historic annual return of 12%:
- Total Amount Invested: $120,000
- Estimated Wealth Created (Gains): $379,574
- Total Portfolio Value: $499,574
Notice that more than 75% of your final portfolio value comes purely from compounded interest, not from the principal you deposited!
