The Need to Invest
Before we start throwing fancy graphs at you, let's picture the "no-invest" scenario.
This chapter will change how you think about money. By the end, you'll understand why investing isn't optional—it's essential.
Why Should You Invest?
You pull in ₹50,000 a month, spend ₹30,000 on the usual suspects – rent, food, Uber, Netflix, doctor visits. That leaves you with a ₹20,000 surplus each month.
Let's make some assumptions:
- Your salary grows by 10% every year
- Inflation runs at 8% per year
- You're 30 today and plan to retire at 50
- Your lifestyle expenses are frozen in time
What Happens When You Don't Invest?
If you just let that cash gather dust for 20 years, you'll end up with roughly ₹1.7 crore. Sounds nice, right?
But here's the catch: Your expenses are still climbing at 8% per year, so that ₹1.7 crore only funds about 8 years of post-retirement life!
The Power of Compounding
Now imagine you invest that ₹20,000 a month in something that grows at 12% p.a.:
Your corpus after 20 years swells to ≈ ₹2 crore. That's 2.4× the "no-invest" pile!
// Future Value of Monthly SIP
function calculateSIPValue(monthly, rate, years) {
const r = rate / 100 / 12; // Monthly rate
const n = years * 12; // Total months
// FV = P × [(1+r)^n - 1] / r × (1+r)
return monthly * ((Math.pow(1 + r, n) - 1) / r) * (1 + r);
}
// Example: ₹20,000/month at 12% for 20 years
const corpus = calculateSIPValue(20000, 12, 20);
console.log(`Final Corpus: ₹${corpus.toLocaleString()}`);Quick Check
