What does the fee really cost your SIP?

A fee of 1.5% a year sounds like nothing. It is charged every year, on your whole balance, in good years and bad. Put in your own numbers and see what it takes.

How this is calculated

Each option earns the market return minus its fee. We turn that yearly rate into a monthly one, then apply the standard future-value formula for a monthly investment, with each instalment invested at the end of the month. This is the same method used in Chapter 4 of The Last Salary, so you can reproduce it with any calculator. 12% is an assumption, not a guarantee. Real returns vary year to year, and taxes are not included.

The fee is only half of it

A low fee builds a bigger corpus. It still does not pay you a rupee until you start selling it. That is the other half of the argument.
