Each of these tools does something different. This blog will explain when to use them, how they work, and what kind of investor each tool is meant for.

📊 Index Fund Calculator — For Passive Mutual Fund Investors

This Calculator helps you calculate returns from investing in index funds. These funds copy a market index like Nifty 50 or Sensex. They’re simple, low-cost, and don’t need much tracking.

Perfect for:

  • Long-term investors
  • People who want to invest passively
  • SIP or lump sum planning in index funds

📌 Inputs:

  • Monthly investment (or lump sum)
  • Time period (in years)
  • Expected return (usually 10–12%)

It gives:

  • Total investment
  • Estimated return
  • Final portfolio value

💡 Example:

If you invest ₹5,000/month in a Nifty index fund for 10 years at 11%,
→ Final value ≈ ₹10.3 lakh
→ Invested: ₹6 lakh
→ Interest: ₹4.3 lakh

Simple, no-fuss tool for passive investing.
