Wealth Erosion Formula
Calculates the difference in wealth accumulation when the gross return is reduced by the annual fund management fee (expense ratio).
Worked Example: ₹10,000 monthly SIP over 20 years at 12% returns with 1.5% expense ratio
The Silent Fee: How a 1.5% Expense Ratio Stole ₹17 Lakhs From a 20-Year SIP
When Kavita invested in an active equity fund, the 1.5% annual expense ratio seemed trivial. "It's just one and a half percent," she reasoned. "If the fund makes 12%, I still get 10.5%." What she didn't realize was how compounding applies to fees.
Kavita set up a ₹10,000 monthly SIP for 20 years. At a gross return of 12% p.a., her corpus would have grown to ₹99.9 Lakhs. But after the fund deducted its 1.5% annual expense ratio, her realized returns dropped to 10.5% p.a., resulting in a final corpus of ₹82.8 Lakhs. Kavita paid ₹17.1 Lakhs in fees — money that was directly deducted from her compounding capital.
Expense ratio is the annual fee charged by mutual funds to manage your money. It is calculated daily and deducted from the NAV. Over long horizons, a small difference in expense ratio compounds into a massive difference in final wealth.
Before choosing an active fund, check its expense ratio. If the fund cannot consistently beat the index by a margin wider than its fee, you are better off investing in a low-cost index fund with an expense ratio of 0.1% to 0.2%. Every basis point you save stays in your portfolio to compound.
