FD vs SIP — Frequently Asked Questions
Is SIP always better than FD?+
Not always. SIP in equity mutual funds has historically outperformed FD over 7+ year horizons, but carries market risk. Over short periods (1-3 years), FD may deliver more predictable returns. FD is better for: capital preservation, short-term goals, retirees. SIP is better for: long-term wealth creation (10+ years), beating inflation, tax efficiency via LTCG.
How is FD interest taxed vs SIP returns?+
FD interest is taxed every year at your income tax slab rate (5%, 20%, or 30%) plus cess. Equity SIP held 12+ months: LTCG above ₹1.25L taxed at 12.5%. Equity SIP held under 12 months: STCG at 20%. Debt fund SIP: taxed at slab rate. So equity SIP has a significant tax advantage for long-term investors in the 20-30% slabs.
What return should I expect from equity SIP?+
Historical CAGR for equity mutual funds over long periods: Large-cap: 11-13%, Mid-cap: 14-17%, Small-cap: 16-20%. Nifty 50 average CAGR (1995-2024): ~14%. Our calculator default is 12% which is a conservative estimate for large-cap or flexi-cap funds. Past performance doesn't guarantee future returns.
Can I combine FD and SIP in one portfolio?+
Yes — most financial planners recommend exactly this. A common approach is to keep 3-6 months of expenses in FD or a liquid fund as an emergency buffer, then direct the rest of your monthly surplus into SIP for long-term goals. This "core-satellite" split gives you FD's safety for near-term needs and SIP's growth potential for goals 7+ years away, rather than betting everything on one instrument.
Does SIP guarantee returns like FD does?+
No. FD returns are contractually fixed at the time of booking — you know exactly what you'll receive at maturity. SIP returns depend entirely on market performance and are never guaranteed; a SIP that has compounded at 12-14% historically could still show a loss in any given short window, especially in the first 1-3 years. This is why SIP suits money you won't need for at least 5-7 years, giving market volatility time to average out.
How does inflation affect the FD vs SIP decision?+
India's average retail inflation has run around 5-6% in recent years. A 30%-slab taxpayer earning 7.1% FD interest nets roughly 4.97% post-tax — barely ahead of inflation, or even behind it in high-inflation years. Equity SIP's long-term average of 12-14% offers a meaningfully larger real (inflation-adjusted) return, which is the core reason SIP is generally favored for long-horizon wealth goals like retirement, even though it carries short-term volatility that FD doesn't.
FD vs SIP — Which Should You Choose in 2026?
The Fixed Deposit vs SIP question comes down to one core tradeoff: guaranteed but modest returns (FD) versus variable but historically higher returns (SIP in equity mutual funds). Neither is universally "better" — the right choice depends on your time horizon, risk tolerance, and what the money is for.
Worked Example: ₹10,000/Month for 10 Years
Investing ₹10,000 every month for 10 years (₹12 lakh total invested) in an FD at 7.1% post-tax (30% slab) grows to roughly ₹16.8 lakh. The same ₹10,000/month in an equity SIP averaging 12% grows to roughly ₹22.6 lakh before tax, and about ₹21.4 lakh after LTCG tax — a gap of nearly ₹4.6 lakh in SIP's favor over this horizon, though that gap isn't guaranteed and depends entirely on how markets actually perform over those 10 years.
When FD Makes More Sense Than SIP
FD wins for money you'll need within 1-3 years, for capital you cannot afford to see drop in value (a house down payment due next year, for instance), and for investors — particularly retirees — who prioritize predictability over growth. SIP wins for goals 7+ years away where you can ride out market cycles, and for investors in higher tax brackets seeking the more favorable long-term capital gains treatment equity funds offer versus FD's annual slab-rate taxation.
