What is the direct savings calculator?
You can use the direct savings calculator to find out the amount of money you can save just by investing in the direct plan o the fund instead of a regular plan.
These additional savings in direct funds is because direct plans have an expense ratio lesser than that of regular plans. The expense ratio is the fee charged by asset management companies to cover costs like management fee, agent commissions, registrar fees, and selling and promoting expenses etc.
To learn more about expense ratio refer this article.
The direct savings calculator tells you the difference in expense ratio and the impact this has over a long period (5,10,15,20,25 years)
You can pick the investment type i.e., lump sum or SIP, the investment amount and the duration along with an expected return to see how much you would stand to save in terms of money and percentage at the end of the investment period.
