How do I know the expense ratio of my mutual funds purchased through NJ India Invest?

You can easily find the expense ratios of the funds that you have invested in by visiting the Mutual Fund House’s website.

But if i understand your question is the commission expense that you are incurring no the current platform, then the answer is simple too.
