The SIP vs Fixed Deposit debate is one of India's most common personal finance questions. Both are popular, but they serve different purposes — and the after-tax, after-inflation returns differ dramatically. This guide compares both using a plan calculator approach for the three most common investment horizons.
SIP vs Fixed Deposit: Core Differences
| Feature | SIP (Equity Mutual Fund) | Fixed Deposit |
|---|---|---|
| Expected Returns | 10–14% p.a. (historical avg) | 6.5–7.1% p.a. (current rates) |
| Risk | Market risk (can fall short-term) | No risk (guaranteed) |
| Tax on Gains | LTCG 12.5% above ₹1.25L (equity) | Income slab rate (up to 30%) |
| Liquidity | T+3 days exit (no lock-in) | Penalty on premature withdrawal |
| Minimum Amount | ₹100–₹500/month | ₹1,000 (varies by bank) |
| Best For | Long-term wealth building | Short-term safety, emergency fund |

Post-Tax Return Comparison (₹5,000/month for 10 years)
| Investment | Total Invested | Corpus (Pre-tax) | Tax (30% bracket) | Net Corpus |
|---|---|---|---|---|
| SIP at 12% | ₹6,00,000 | ₹11,62,000 | ₹64,000 (LTCG 12.5%) | ₹10,98,000 |
| FD at 7% | ₹6,00,000 | ₹8,66,000 | ₹78,900 (income tax 30%) | ₹7,87,100 |
Assumptions: SIP returns compounded; FD interest taxed annually at marginal rate; LTCG ₹1.25L exempt. Illustrative only.
The Inflation Factor
India's average inflation is ~5–6%. An FD at 7% gives a real return of only 1–2%. Equity SIPs at 12% give a real return of 6–7% — dramatically more purchasing power over 15+ years.
When to Choose FD Over SIP
- Emergency fund: FD is ideal — guaranteed, liquid (with small penalty), and no market risk
- Short-term goals (under 3 years): Equity SIPs are volatile short-term; FD is safer
- Very low risk appetite: If market volatility causes anxiety, FD gives peace of mind
- Senior citizens: Special senior citizen FD rates (usually 0.5% extra) make FD more attractive
Bottom line: For goals 5+ years away, SIP historically outperforms FD post-tax. For goals under 3 years or emergency corpus, FD is more appropriate. Many advisors recommend a 70% SIP / 30% FD split for balanced portfolio building.
