I am investing in few Mutual Fund for quite a time. I started investing from 2007 to 2012 through agent and then directly, My MF Investment is still active I want to know exact returns(Including Dividends received) i.e. Returns(Dividend + Present Valuation) . Also I started with Rs 1000/ month, then few months later I changed it to 1500/month again I changed to 2000/month and So on. So How do I calculate?
