You are right. I forgot about the charges for the demat account - there are AMC charges of Rs.300 per year. So that makes zerodha coin about Rs.75 per month.
But there are no transaction charges in zerodha on buying equity (delivery) or MF. So it is still cheaper than piggy for someone wishing to make a large number of transactions or someone who doesn't want an SIP but wishes to invest manually every month.
Also, if you need a demat account for some other purpose - like investing in ETFs or equities then maybe it makes more sense for some people.
If all you are doing is an SIP with a couple of mutual funds, which is what most people around me do, piggy is probably cheaper. You can always have a zerodha (or equivalent) account for equity/ETFs/etc. and piggy for MFs.
But for someone like me with slightly different requirements, zerodha would be cheaper. I have a variable income so SIPs are not an option for me. I invest money as a percentage of my income so the amounts vary every month. In this case zerodha turns out to be cheaper despite the demat charges.
