15 years is a long term, you could choose best SIP to invest your 3000 in a SIP of an Equity Mutual Funds. However there are a few things that you need to consider before starting your investment in Mutual Funds:
Its always advisable to start your investment based on your investment goal. It could be a long term goal (5+ years) like retirement, child’s education, buying a home etc. Or you could have a short term goal (<5 years) like saving for honeymoon, vacation with friends, buying a car/bike etc. Based on the time horizon of your goal you would have to invest in Equity and debt Mutual funds. Goal based investment is a more effective way to make money.
