What is difference between charges imposed on direct MF and regular MF?

suppose I invest lumpsum Rs 10000 for 30 years at 15% return.
then what is difference between charges imposed on direct MF and regular MF?

how much charges will be there on regular MF?
how much charges will be there on direct MF?

You can calculate this yourself on Coin website. Go to any fund page and use the calculator on the right. I have done your above calculation for DSP tax saver - growth - lumpsum (25 years. There is no 30 year option currently).

3.07lks on direct vs 2.51 lks on regular
