A recurring deposit (RD) and a systematic investment plan (SIP) both turn a fixed monthly amount into a lump sum over time, and they differ mainly in what they promise. An RD promises a fixed interest rate for the whole tenure, while a SIP invests in a mutual fund whose returns move with the market and carry no promise.
The SIP vs RD choice therefore depends on what the monthly savings are meant for. Money needed on a fixed date within a few years suits the certainty of an RD, and money for goals five to ten years away or more can use the higher long-term growth that a SIP in equity funds has historically offered, with the risk of a loss in the short term.
SIP vs RD at a glance
| Feature | RD | SIP |
|---|---|---|
| Return | Fixed rate, set at the start for the whole tenure | Market-linked, with no guaranteed return |
| Risk to capital | Very low. A bank deposit is insured up to ₹5 lakh per depositor per bank, and post office RDs carry a government backing. | Varies by fund. Equity funds can fall sharply in the short term. |
| Tenure | Fixed, usually from six months to ten years | Flexible, with no fixed end date |
| Minimum amount | Small, often ₹100 to ₹500 a month depending on the bank | Small, often from ₹100 to ₹500 a month depending on the fund house |
| Liquidity | Premature closure is allowed with a lower interest rate, and banks typically apply a penalty | Units can be redeemed any day, subject to any exit load |
| Flexibility | The instalment is fixed, and missing it can attract a penalty | The amount can be paused, reduced or stopped |
| Tax on returns | Interest is taxed at the slab rate every year | Gains are taxed on redemption at capital gains rates |
What each could look like over five years
As an illustration, ₹10,000 saved every month for five years puts ₹6 lakh into either option. The table below uses an RD at 7% with quarterly compounding and SIP returns of 0%, 4%, 8% and 12% a year, and the SIP returns are assumptions and not forecasts.
| Option | Assumed annual return | Value after five years (before tax) |
|---|---|---|
| RD | 7%, fixed | About ₹7.19 lakh |
| SIP, poor outcome | 0% | ₹6 lakh |
| SIP, weak outcome | 4% | About ₹6.64 lakh |
| SIP, moderate outcome | 8% | About ₹7.34 lakh |
| SIP, strong outcome | 12% | About ₹8.11 lakh |
The RD gives one known number, and the SIP gives a range that depends on the market during those five years. Over a short period the SIP can end below the RD, and over longer periods the range narrows and has tended to move higher for equity funds, with no guarantee.
How the tax differs
| Item | RD | SIP in an equity fund |
|---|---|---|
| Type of income | Interest, taxed as income from other sources | Capital gains on redemption |
| Rate | Slab rate. At the 30% slab with 4% cess, the ₹1.19 lakh of interest in the example leaves about ₹6.82 lakh after tax. | 20% on gains from units held 12 months or less, and 12.5% on long-term gains above ₹1.25 lakh in a financial year |
| Timing | Tax is due each year as interest accrues, with tax deducted at source (TDS) above a yearly threshold | Tax arises only when units are sold |
Each SIP instalment has its own holding period, so units bought earlier qualify for the long-term rate sooner than units bought recently.
Which one suits which goal
| Situation | Option that fits | Reason |
|---|---|---|
| A known expense in one to three years, such as a fee or a down payment | RD | The amount and the date are certain, and a market fall cannot disturb the plan. |
| A goal five to ten years away or more | SIP | A longer horizon gives equity time to recover from falls. |
| Savings that may need to be paused | SIP | The amount can be changed without penalty. |
| A first-time saver who cannot bear a fall in value | RD, or a SIP in a low-risk debt fund | It builds the habit before taking on market risk. |
| A larger goal with both a near and a far part | A mix of both | Each part uses the instrument that matches its horizon. |
What savers should take from this
An RD protects the amount and the date, and a SIP gives up that certainty for the chance of higher long-term growth. The deciding question is how long the money can stay invested and how much of a fall can be tolerated, and many households end up using both for different goals.
Kuvera offers direct mutual funds for SIPs and online fixed deposits, so both kinds of savings can be started in one place.
Frequently Asked Questions
1. Is SIP better than RD?
Neither is better in every case. A SIP suits long-term goals and can grow more over time, and an RD suits short-term goals where the amount and date must be certain.
2. Is the return on a SIP guaranteed?
No. SIP returns depend on the fund’s performance and can be lower than an RD, or even negative, over short periods.
3. Which is safer, SIP or RD?
An RD is safer for the capital. A bank deposit is insured up to ₹5 lakh per depositor per bank, while a SIP carries the market risk of the fund it invests in.
4. How is RD interest taxed?
The interest is added to income and taxed at the slab rate each year, with TDS deducted by the bank above a yearly threshold.
5. Can a SIP be stopped or paused?
Yes. A SIP can be paused, reduced or stopped, and units already bought stay invested.
