If you have a lump sum amount and want to transfer that amount over a period of time to Equity Funds, Systematic Transfer Plan (STP) is the most suitable option for you. Using the STP calculator, you can arrive at a future value of your investments made by investing lump sum amount in a liquid or debt scheme and transferring a portion of it at regular intervals systematically in a piecemeal manner into another eqiuty scheme of the same fund house.
