Let me explain this in another way to what Faisal has. This fund was launched Sep 2014, both direct and regular would have started with a NAV of 10. By investing in direct the NAV is 23.78 and by regular it is 23.18. 2.6% more because this much commission wasn’t paid out. So you would have made 2.6% on your capital.
So NAV for direct will always be more than NAV for regular. When you invest in direct today at higher NAV, in 3 years say 2020, you would have seen direct outperform regular by another 2.6%. For you investing today, the outperformance will be 2.6%, but for the person who invested in 2014, it will be much more than 5.2% (2.6+2.6) as he had invested at NAV of 10.
If you visit Coin page for this fund, you can calculate how much you can save in commission by investing into direct scheme instead of regular. Saving of 23lks in direct if you start a SIP of 10k today (NAV at which you invest doesn’t really matter).
