Most Indians investing in mutual funds through a SIP believe they are doing everything right. Monthly discipline, long-term horizon, trusted broker. What they do not realise is that a structural cost buried inside their investment is quietly compounding against them — every single month, for decades.
Every mutual fund in India exists in two versions — a Regular plan and a Direct plan. Same fund house. Same fund manager. Same stocks in the same proportion. The only difference is cost. Regular plans pay your distributor or broker a trailing commission of anywhere between 0.5% and 1.5% every year, deducted from your returns automatically. Direct plans pay nobody. You buy straight from the AMC, the expense ratio is lower, and every basis point saved compounds in your favour.
A Rs 25,000 monthly SIP over 20 years, assuming a regular plan delivers 10% net of all expenses, grows to approximately Rs 1.89 crore. The same SIP in a direct plan of the identical fund, at 11.2% net of expenses, grows to Rs 2.27 crore. Same investor. Same fund manager. Same market. A difference of nearly Rs 38 lakh — handed over to a distributor who made no investment decision on your behalf, took no market risk, and in many cases had a conversation with you exactly once.
Over 30 years, that gap does not double. It multiplies. The power of compounding works identically on costs as it does on returns — just in the opposite direction.
The tragedy is not that brokers exist. Distribution has a role. The tragedy is that most investors have never been shown this comparison. The broker is often a family friend, a colleague, a relative on the group chat. The math never comes up.
SEBI made Direct plans mandatory in 2013. Over a decade later, the majority of retail SIP money still sits in Regular plans.
Your SIP is not broken. But if you have never checked whether you are in a Regular or Direct plan, the answer is almost certainly Regular — and the cost is compounding right now.
