A mutual fund is a pool of money collected from thousands of investors, managed by a professional fund manager who buys stocks, bonds, or other assets on your behalf.
The Samosa Analogy
Imagine 100 people each give ₹100 to a chef. The chef has ₹10,000 to buy ingredients and makes 200 samosas. Each person gets 2 samosas proportional to their investment. If samosas sell well, everyone profits. If they don't, everyone shares the loss. The chef charges a small fee (expense ratio) for his work.
What Is NAV?
NAV (Net Asset Value) is the price of one “unit” of a mutual fund. If the fund holds ₹100 crore in assets and has 10 crore units, NAV = ₹10. When you invest ₹10,000 at NAV ₹10, you get 1,000 units.
Next month, if the stocks the fund holds go up, NAV rises to ₹11. Your 1,000 units are now worth ₹11,000. You made ₹1,000 without doing anything.

Growth vs Dividend Option
Always choose Growth. In Growth, profits are reinvested — your money compounds. In Dividend (now called IDCW), profits are paid out and taxed immediately. Growth is more tax-efficient and builds more wealth.
