Quick Answer: At SBI's best FD rate of 6.80% (as of December 2025), a ₹5,000/month FD-equivalent investment over 10 years gives approximately ₹8.30 lakhs. The same ₹5,000/month SIP at 12% gives ₹11.62 lakhs. For timeframes of 5 years or more, equity SIP has historically outperformed FD by a significant margin, but FD carries zero risk of capital loss.
The FD feels safer. But over 10 years, the math tells a different story.
FD is the investment that every Indian family swears by. It's in your parents' documents. It's what the bank relationship manager always suggests. And for decades, it made sense — FD rates were 9–12% in the 1990s and early 2000s.
But today, SBI's best FD rate for general public is 6.80%*
4.76%**.
Inflation in India has averaged around 5–6% per year over the past decade.
That means a 30% taxpayer's FD is currently delivering negative real returns. Let's dig into the full picture.

When FD Is the Right Choice
- Short-term goals (under 3 years): Equity SIP is too volatile for a 2-year horizon. FD guarantees your capital and a fixed return — right choice for short-term goals.
- Emergency fund: FD (or liquid fund) is appropriate. Don't keep your emergency fund in equity.
- Risk-averse investors: If you'll panic and withdraw when the market drops 20%, you shouldn't be in equity SIP. FD is better than stopping a SIP mid-way.
- Senior citizens: FD rates for seniors are 0.5% higher (SBI: up to 7.05%). With simpler tax treatment and guaranteed income, FD serves senior citizens well.
When SIP Is the Right Choice
- Goals 5+ years away: Market volatility smooths out over time; SIP in equity consistently beats FD.
- Tax-efficient wealth creation: LTCG at 12.5% (with ₹1.25L annual exemption) is much better than FD interest taxed at your slab rate (up to 30%).
- Inflation-beating growth: FD at 6.05–6.80% barely beats 5–6% inflation before tax. After tax, it often doesn't.
- Flexible investment: Unlike FD, a SIP has no lock-in — you can stop, pause, or withdraw anytime.
Key Takeaways
- FD at 6.80% (SBI best rate) = ~4.76% post-tax for 30% bracket holders. Barely inflation-matching.
- SIP at 12% over 10 years = net ₹10.97 lakhs vs FD's ₹7.61 lakhs — a ₹3.36 lakh difference on ₹6 lakh invested.
- Use FD for: short-term goals, capital safety, emergency parking, senior income.
- Use SIP for: wealth creation, retirement, goals 5+ years away, tax-efficient growth.
Frequently Asked Questions
No, FD is safer from a capital protection standpoint. In SIP, the NAV can fall and your portfolio can show negative returns. Over long periods (7–10+ years), equity SIP has historically delivered significantly higher returns, but with short-term volatility.
SBI's best FD rate in 2025 is 6.80% p.a. Historical equity SIP returns (Nifty 50 index funds) over 10–15 year periods have averaged 10–13% CAGR. However, short-term SIP returns can be negative.
Absolutely. A common approach: keep 3–6 months of expenses in FD (emergency fund), invest long-term wealth in equity SIP, and use a short-term debt fund for goals 1–3 years away.
