Why Small Costs Quietly Wreck Returns
A 1% annual cost sounds tiny. Over 25 years it can eat a quarter of your wealth. The math.
We obsess over picking the right stock and shrug at a “small” 1% fee. That instinct is exactly backwards — because costs compound against you just as relentlessly as returns compound for you.
Example₹10 lakh invested for 25 years at 12%: with no fee it grows to ~₹1.70 crore. Shave just 1% off (11% net) and it becomes ~₹1.36 crore. That “tiny” 1% quietly cost you ~₹34 lakh — about 20% of your final wealth.
Lost wealth ≈ corpus × (1 − ((1+net)/(1+gross))^years)
A small annual gap, raised to the power of many years, becomes a large fraction of the end result.
Costs are the one variable you fully control and that compounds with certainty. You can’t guarantee returns, but you can guarantee lower fees — and over decades that’s often worth more than any stock pick. This is the entire case for low-cost index fundsA fund that simply tracks a market index at very low cost. (Investing track).
Key takeawayA 1% annual cost can erase ~20%+ of a 25-year corpus. Costs compound against you with certainty — minimise them ruthlessly.
FAQs
Where do these hidden 1% costs come from?
Mainly mutual-fund expense ratios (especially regular vs direct plans), advisory fees, and frequent-trading charges. Switching to direct plans and low-cost index funds, and trading less, are the simplest ways to claw back that 1%.
