Analysis shows a 10-year investment in a low-performing flexi-cap fund grew to ₹2.53 crore pre-tax, surpassing the ₹2.01 crore from a top-rated fixed deposit. The gap widens significantly after taxes, as equity gains benefit from a lower flat tax rate compared to the slab-based taxation on FD interest.
For many Indian investors, the safety of a bank fixed deposit (FD) is a primary consideration. However, holding large amounts in these instruments over long periods involves an often-overlooked cost related to taxation and inflation. A recent comparative analysis of 10-year returns demonstrates how equity investments, even when they underperform their category, can lead to better wealth accumulation than the highest-yielding fixed deposits.
The Impact of Taxes on Long-Term Wealth
The fundamental difference between these two investment paths lies in how the tax department treats their gains. Interest earned from a fixed deposit is added to your annual income and taxed according to your specific tax slab, which can be as high as 30% plus surcharges. This annual tax outgo reduces the amount of capital available to compound over time.
In contrast, equity mutual funds are taxed only when you sell your units. Currently, long-term capital gains on equity are taxed at a flat rate of 12.5% on gains exceeding ₹1.25 lakh. This structure allows the entire investment to benefit from compounding for the full duration of the holding period. Over a decade, this difference in tax treatment significantly boosts the post-tax return of equity funds compared to fixed deposits.
Comparing Performance and Risk
When examining the data, the Taurus Flexi Cap Growth fund—often cited as a lower-performing flexi-cap fund over the last decade—delivered a compound annual growth rate (CAGR) of 9.71%. A starting investment of ₹1 crore in this fund would have grown to ₹2.53 crore before taxes. For comparison, the best-performing fixed deposit from Suryoday Small Finance Bank during the same period offered 7.25%, turning the same ₹1 crore into ₹2.01 crore pre-tax. This represents a pre-tax difference of approximately 25% in favor of the equity fund.
Investors often look at arbitrage funds as an alternative for stability. While the Kotak Arbitrage Fund Regular delivered returns that trailed the top FD on a pre-tax basis, its tax advantage allows it to compete closely with fixed deposits on an after-tax basis. Arbitrage funds provide the added benefits of higher liquidity and the absence of premature withdrawal penalties often found in bank deposits.
Balancing Safety and Purchasing Power
While this data highlights the efficiency of equity over a 10-year horizon, it is not an argument to ignore risk or abandon fixed deposits entirely. Fixed deposits serve a specific purpose, particularly for emergency funds and short-term capital preservation where volatility must be avoided. However, if funds are earmarked for long-term goals and are not required for emergencies, the implicit cost of choosing an FD solely for perceived safety becomes material. Investors may want to evaluate whether their long-term savings are losing purchasing power to inflation and taxes, and whether their portfolio allocation aligns with their time horizon and financial goals.
