How to calculate present amount of money that I invested in Mutual Funds.?

I invested Rs 7000 (~$150) a month for 24 months in a DSP mutual fund. That makes Rs 1,68,000 principle amount. Now stock market in India is doing good. My Mutual fund’s N.A.V have also gone a little up. I am planning to take money out. But I want to know present value of my invested money also what kind of taxes I have to pay while taking out money.
