FD vs Stocks Calculator

Fixed Deposits vs. Stocks — The Real Comparison

Bank FDs are the default investment for most Indian households. They are safe, simple, and guaranteed. But the safety comes at a cost: FD returns, once adjusted for inflation and taxes, are frequently negative in real terms.

Stocks carry real risk of capital loss. But over long periods — 15 to 20 years or more — equity returns in India have consistently exceeded inflation and FD returns. The question is not which is better absolutely, but which mix is appropriate for your risk tolerance, time horizon, and tax situation.

Post-Tax FD Returns at Different Tax Slabs

FD interest is added to your income and taxed at your marginal slab rate. For a senior taxpayer in the 30% bracket, a 7% FD generates a post-tax return of just 4.9%. TDS (Tax Deducted at Source) at 10% is deducted by the bank on FD interest above ₹40,000 per year (₹50,000 for senior citizens).

Equity Returns — Historical Context

Nifty 50 has delivered approximately 13-14% CAGR over the past 20 years. With LTCG tax of 12.5% (on gains above ₹1.25 lakh annually) and assuming 6% average inflation, the real post-tax return from equity has been in the range of 6-8% — significantly better than FDs for investors in higher tax brackets.

The catch: that 13% CAGR came with multiple 30-50% drawdowns. 2008: Nifty fell 60%. 2020: fell 38% in 40 days. 2015-2016: sideways for 18 months. An investor who panicked at any of these points and moved to FD would have locked in losses and missed the recovery.

Time horizon is the key variable. For money needed in under 3 years, FD is appropriate regardless of tax slab — the volatility risk of equity is too high. For 7+ year horizons, equity has historically been the better choice for investors who can tolerate the interim volatility.

Sharpe Ratio — Risk-Adjusted Returns Matter

Returns alone do not tell the full story. An investment that returns 12% with wild swings is not necessarily better than one that returns 9% with steady, predictable growth — especially for investors close to retirement or with specific liquidity needs.

Sharpe Ratio = (Portfolio Return − Risk-Free Rate) ÷ Standard Deviation of Returns. A higher Sharpe means better return per unit of risk taken. For most 10-year periods, diversified equity mutual funds have had Sharpe ratios of 0.5-0.8, while FDs have Sharpe close to 0 (since they have near-zero volatility but also near-zero real returns post-tax and post-inflation).

The right comparison for a 30-year-old with stable income: build an equity-heavy portfolio for long-term wealth, keep 6-12 months of expenses in FD or liquid funds as emergency reserve. Do not let the entire corpus sit in FD because it feels safer — that safety is slowly eroding purchasing power.
