SIP vs FD: which is better for you?
The honest answer depends on two things: how long the money can stay invested, and what you need at the end. The framework below covers the question most readers actually have. A side-by-side calculator is in progress and will live on this page.
The short version
- Horizon under 3 years. FD almost always wins. Equity is too volatile to be trusted with money you’ll need soon.
- Horizon 3 to 7 years. Mixed. A debt-heavy hybrid fund or balanced advantage fund usually fits better than either pure FD or pure equity.
- Horizon 7 years or more. SIP in equity mutual funds typically wins by a meaningful margin, after adjusting for inflation and tax. The longer the horizon, the larger the gap.
Why the gap grows over time
A 6.5% FD compounds at 6.5%. An equity SIP, over long horizons, has historically compounded at 11-13% in nominal terms. That 5-6 percentage point gap looks small in any single year. Over 20 years it roughly doubles the ending corpus.
The trade-off is the path. An FD doesn’t lose value in a bad year. An equity SIP can be 30% down for stretches. Staying invested through those stretches is the whole game.
Where the comparison gets harder
- Tax. FD interest is taxed at your slab rate, often 30% or more. LTCG on equity is currently 12.5% above the ₹1.25 lakh annual exemption. Over long horizons, this changes the effective return materially.
- Liquidity. FDs can be broken with a small penalty. Equity SIPs can be exited any day, but at whatever the market value happens to be on that day.
- Goal certainty. If the goal value is non-negotiable (a school fee due in 18 months), FD. If the goal is flexible (“retire comfortably”), SIP.
In the meantime
For the equity side of the comparison, the SIP calculator already shows the projected corpus, inflation-adjusted real value, and post-tax corpus. The interactive head-to-head against an FD will be added here.
FAQs
Is SIP better than FD for long-term investment? ▾
For horizons of 7 years and beyond, equity SIPs have historically returned 11-13% per year while FDs return 6-7%. Over 20 years, that gap roughly doubles the ending corpus, even after tax. For shorter horizons, equity volatility makes FDs the safer choice. Which is "better" depends on how long the money can stay invested without you needing it.
Are SIP returns guaranteed like FD interest? ▾
No. FD interest is contractually fixed when you open the deposit. SIP returns are market-linked and vary year to year, sometimes sharply. Long-term averages have been higher for equity SIPs than for FDs, but no single year is guaranteed, and equity SIPs can be 20-30% down for stretches before recovering.
How is tax on SIP returns different from FD interest? ▾
FD interest is added to your income and taxed at your slab rate, which is 30% or more for many salaried earners. Long-term capital gains on equity mutual funds (held over one year) are taxed at 12.5% above an annual ₹1.25 lakh exemption. On large amounts over long horizons, the post-tax gap between the two is often larger than the pre-tax gap.
Can I do both SIP and FD at the same time? ▾
Yes, and most balanced portfolios do. The right split depends on when you need the money. Short-term goals (1-3 years) belong in FDs or liquid funds; long-term goals (7 years or more) typically belong in equity SIPs. The two solve different problems and can sit in the same portfolio without conflict.
