The Hidden Friction of Expense Ratios

When investing in Indian mutual funds, one of the most consequential decisions investors overlook is plan selection: Direct Plans vs. Regular Plans. While both variants share identical portfolio compositions, stocks, and fund managers, their net asset values (NAVs) diverge continuously due to distribution commissions embedded in regular plans.

1. How Distributor Commissions Compound Against You

Regular plans carry an additional 0.50% to 1.25% annual Total Expense Ratio (TER) paid as trailing brokerage to distributors. Over a 15 to 25 year investment horizon, this spread acts as a relentless drag on compounding returns.

  • Monthly SIP of ₹25,000 for 20 years at 13% gross return:
  • Direct Plan (TER 0.70%): Yields approx ₹2.42 Crore
  • Regular Plan (TER 1.70%): Yields approx ₹1.98 Crore
  • Net Loss to Intermediary Fees: ₹44 Lakhs
