Consider an example to see how the growth and dividend reinvestment options work in practice. Suppose that you invest Rs. 60,000 in a mutual fund with an initial NAV of Rs. 12 per unit. This gives you 5,000 units of the fund. Now, after one year, the NAV rises to Rs. 18 per unit, and the fund declares a dividend of Rs. 2 per unit.
Dividend reinvestment option
In the dividend reinvestment scenario, you will get a dividend of Rs. 10,000 (5,000 units × Rs. 2 dividend per unit). But instead of receiving this amount in cash, the dividend is used to buy more units of the fund. At the adjusted NAV of Rs. 16 (due to the dividend payout), you will get an additional 625 units (Rs. 10,000 / Rs. 16 per unit). You now hold 5,625 units in total.
However, the NAV has reduced to Rs. 16 per unit, so the total value of the investment is Rs. 90,000 (5,625 units × Rs. 16 per unit).
Growth option
In the growth option, there is no dividend payout, so the NAV remains at Rs. 18 per unit. Your 5,000 units are now worth Rs. 90,000 (5,000 units × Rs. 18 per unit). There are no additional units in this case, but the NAV has risen to reflect the reinvested profits.
At first glance, the total value looks identical in both scenarios. However, taxation can significantly affect your overall returns.
