SIP vs Fixed Deposit
No Sign-Up. No Paywall.
Equity SIP vs bank FD after tax — the classic safe-vs-growth debate with real ₹ numbers.
What SIP in Equity Funds and Fixed Deposit Actually Mean
SIP in Equity Funds. A monthly instalment into an equity mutual fund. You own units whose value moves with the market, so neither the return nor the final amount is promised to you in advance.
Fixed Deposit. A deposit with a bank or NBFC for a fixed term at a rate agreed on the day you open it. The maturity amount is contractually known from day one and does not change.
The real distinction is not “risky versus safe”. It is who carries the uncertainty. With an FD the bank carries it and pays you a fixed rate for the privilege. With an equity SIP you carry it, and the compensation for doing so is the possibility — not the guarantee — of a higher return.
Key Differences
| Feature | SIP (Equity) | Fixed Deposit |
|---|---|---|
| Returns | Market-linked (8–15% historical) | Fixed (6.5–7.5% current) |
| Risk | Market risk | No risk — guaranteed |
| Tax (after 1 yr) | LTCG 12.5% above ₹1.25L | TDS at 10%; slab rate tax |
| Liquidity | High (exit anytime) | Penalty on premature withdrawal |
| Ideal for | Wealth creation, 5+ years | Capital preservation, short term |
| Is the maturity amount known upfront | No | Yes, at the contracted rate |
| Taxed on | Gains, only when you redeem | Interest accrued each year, whether withdrawn or not |
| Deposit protection | None — market instrument | DICGC cover up to ₹5 lakh per bank per depositor |
| Effect of inflation | Return may exceed it, but is not assured | A fixed rate can fall below it in real terms |
When to Choose Which
Choose SIP (Equity)
- Investment horizon is 5+ years
- You can handle short-term market fluctuations
- You want inflation-beating returns
- Building a retirement corpus
Choose Fixed Deposit
- You need guaranteed returns
- Short-term parking (1–3 years)
- Risk-averse or retiree portfolio
- Emergency fund component
Worked Examples
The calculator above compares maturity values. What it cannot show is the range of outcomes, which is the real difference between the two.
| Scenario | SIP in Equity Funds | Fixed Deposit |
|---|---|---|
| ₹10,000 a month for 10 years | Outcome depends on market path — a wide range | A single known figure at the contracted rate |
| Money needed in 18 months | Poor fit — too short for equity to recover a fall | Well suited — the amount is certain |
| Retirement corpus 20 years out | Long enough for equity risk to be worth taking | Safe, but a fixed rate may lose to inflation over 20 years |
Note what the middle row implies: for a short goal, an FD is not the cautious choice — it is the correct one. Equity is not a better product; it is a product for a different job.
How Each Is Taxed
The tax treatment differs in timing as well as rate, and the timing difference is the one people miss. FD interest is taxed every year as it accrues, at your slab rate, whether or not you withdraw it. Banks deduct TDS at 10% under section 194A once interest crosses ₹50,000 in a year (₹1 lakh for senior citizens), and 20% if no PAN is on record — but TDS is only an advance, and the full slab-rate liability still applies. Equity fund gains are taxed only when you redeem. Units held 12 months or more are taxed at 12.5% under section 112A, with the first ₹1.25 lakh of such gains each year exempt; units held less than 12 months are taxed at 20% under section 111A. For a taxpayer in the 30% bracket this gap is large, and it compounds: money not paid in tax each year stays invested.
These rules apply to both FY 2025–26 and FY 2026–27 — Budget 2026 made no change to capital gains rates or holding periods.
Advantages and Limitations
SIP in Equity Funds
Works for you when
- Your horizon is five years or longer
- You want a chance of beating inflation after tax
- You can leave the money alone through a fall
Watch out for
- No guarantee — you can finish below what you put in
- A bad sequence near your goal date hurts most
- Requires you not to sell at the bottom
Fixed Deposit
Works for you when
- The money is needed within one to three years
- The amount must be certain
- It is your emergency fund or a near-term commitment
Watch out for
- Interest is taxed annually at slab rate, even if untouched
- A fixed rate can trail inflation for years
- Breaking early usually costs a rate penalty
How to Decide
Decide by the goal, not by which sounds safer.
- When do you need the money? Under three years — FD. Over seven — equity deserves serious consideration.
- Must the amount be exact? A school fee or a down payment with a fixed date argues for an FD regardless of returns.
- What is your slab rate? At 30%, annual taxation of FD interest is a material drag that the headline rate hides.
- Is this your emergency fund? Then the answer is FD, and the return is not the point.
- Is it long-term money you will not touch? Then holding it all in an FD carries its own risk — the risk of falling behind prices.
Most people need both, in different buckets. The mistake is not choosing wrongly between them; it is using one instrument for every job.
