RD vs SIP: Which Monthly Investment Grows Your Money Faster?
Both ask you to invest every month — but only one can genuinely beat inflation over the long term.
Recurring Deposits (RDs) and Systematic Investment Plans (SIPs) are India's two most popular "save a little every month" instruments. Both demand monthly discipline. Both are accessible to salaried earners with as little as ₹500/month. But beyond that, they are fundamentally different products serving different purposes. Choosing the wrong one for your goal can cost you lakhs over time.
What Is an RD?
A Recurring Deposit is a bank product where you deposit a fixed amount every month for a chosen tenure (6 months to 10 years). At maturity, you receive your principal plus compound interest. RD rates today (June 2026) typically range from 6.5% to 7.5% per annum for major banks.
Key features:
- Guaranteed returns, no market risk
- Interest rate is locked at the time of opening
- Premature withdrawal attracts a penalty (typically 0.5–1%)
- Interest is taxed at slab rate every year (TDS applies if annual interest exceeds ₹40,000)
What Is a SIP?
A Systematic Investment Plan is a mode of investing in mutual funds — typically equity, hybrid, or debt funds — by contributing a fixed amount every month. The money buys mutual fund units at the current NAV. Returns are market-linked.
Key features:
- Returns vary based on market performance (no guarantee)
- Can be paused or stopped without penalty after exit load period
- LTCG on equity SIP: 12.5% on gains above ₹1.25 lakh (FY 2025-26)
- Historically, equity SIPs have outperformed RDs over 7+ year horizons
Side-by-Side Comparison
| Parameter | Recurring Deposit | SIP (Equity Mutual Fund) |
|---|---|---|
| Returns | 6.5–7.5% (guaranteed) | 10–14% (historical, not guaranteed) |
| Risk | Zero (up to ₹5L DICGC insured) | Market risk; can fall short-term |
| Taxation | Slab rate on interest annually | LTCG 12.5% on gains at redemption |
| Liquidity | Penalty on early withdrawal | Flexible (exit load in year 1) |
| Minimum amount | ₹100/month (most banks) | ₹500/month (most AMCs) |
| Inflation protection | Low (returns barely exceed CPI) | High (equity beats inflation long-term) |
| Suitable tenure | 6 months – 3 years | 5+ years |
The Numbers: ₹5,000/Month Over 10 Years
RD Scenario:
Monthly deposit: ₹5,000
Tenure: 10 years (120 months)
Rate: 7% p.a.
Maturity value ≈ ₹8.65 lakh
Interest earned ≈ ₹2.65 lakh
Tax (30% slab): ~₹79,500
Post-tax corpus ≈ ₹7.86 lakh
SIP Scenario:
Monthly SIP: ₹5,000
Tenure: 10 years
Expected return: 12% p.a.
Corpus ≈ ₹11.5 lakh
Gain ≈ ₹5.5 lakh
LTCG tax (12.5% above ₹1.25L): ~₹53,000
Post-tax corpus ≈ ₹11.0 lakh
Difference: SIP wins by ~₹3.14 lakh post-tax
Extend the horizon to 15 years and the gap widens to ₹8–12 lakh on the same ₹5,000/month investment.

When RD Is the Better Choice
Despite SIP's long-term superiority, RDs are the right tool when:
- Tenure is under 3 years — Market fluctuations can leave equity SIPs in the red at short horizons. For a goal in 18 months, capital protection matters more than growth potential.
- Goal is fixed and non-negotiable — A child's school admission fee due in 2 years cannot afford market volatility. An RD guarantees the exact amount.
- Investor has zero risk tolerance — Watching a portfolio fall 20% and continuing to invest requires emotional resilience. For investors who would panic-withdraw at a correction, an RD is a safer behavioural choice.
- Already have adequate equity exposure — If your portfolio is heavily equity, an RD adds uncorrelated stability.
Tax-Optimised Strategy: Combine Both
Many financial planners recommend a hybrid approach:
Monthly savings: ₹15,000
→ ₹5,000 in RD for 2-year near-term goal (emergency buffer)
→ ₹10,000 SIP in equity index fund for 10+ year retirement goal
This way, the guaranteed RD handles short-term needs while the SIP builds long-term wealth. As the near-term goal is met and the RD matures, the proceeds can be redirected to a top-up SIP.
What About Post Office RDs?
Post Office RDs currently offer ~6.7% per annum (compounded quarterly), backed by the Government of India — zero credit risk even beyond the ₹5 lakh DICGC limit. They are excellent for risk-averse investors who want guaranteed returns with sovereign safety but do not need the higher long-term growth of equity SIPs.

Frequently asked questions
Is SIP safer than RD for a 5-year investment in India?+
At 5 years, equity SIPs carry moderate risk — historically, most 5-year SIP periods in Nifty 50 have been positive, but there have been exceptions. For money you absolutely cannot afford to lose at the end of 5 years, an RD or short-duration debt fund is safer. For wealth building where a slight shortfall is acceptable, SIP has outperformed RDs at 5 years in most historical periods.
Can I get tax benefit from an RD?+
No. RDs do not qualify for any deduction under the Income Tax Act. Only 5-year bank FDs qualify for Section 80C deduction (not RDs). If you need tax benefit from a monthly investment, ELSS SIP is the relevant instrument.
What happens if I miss an RD instalment?+
Most banks charge a late payment penalty (₹1–2 per ₹100 per month). If you miss multiple instalments, the RD may be treated as a premature withdrawal or converted to a savings account. SIPs, in contrast, simply skip that month with no penalty — your future SIP instalments continue normally.
Which is better for a 2-year house down payment goal — RD or SIP?+
RD is better for a 2-year down payment goal. The amount is fixed, the goal is time-bound, and you cannot afford a market correction to reduce your available capital. Park the money in an RD or short-duration debt fund to guarantee the amount at the time of need.
Do I need a demat account for SIP?+
No. Regular mutual fund SIPs can be started directly on AMC websites, MF Central, or apps like Groww, Zerodha Coin, or Paytm Money without a demat account. Only ETF-based investments require a demat account.
