RD vs SIP, which is better for a 3 to 5 year goal depends on how much risk the goal can take. A recurring deposit gives a fixed, known maturity amount, but its interest is taxed at your slab rate. An equity SIP can earn more and is taxed more lightly, but its value can fall close to your deadline.
Both are monthly saving habits, and both start with small amounts. The difference lies in where the money goes, how it is taxed, and what happens if markets or interest rates move against you. Below, each option is broken down with current tax rules as of October 2026 and a worked example.
How a recurring deposit works
In a recurring deposit (RD), you deposit a fixed amount every month with a bank or post office for a fixed term. The interest rate is locked on the day you open the account and does not change for the full term. At maturity, you get your deposits plus the interest earned.

The Post Office 5-year RD, for example, pays 6.7% a year, compounded quarterly, for the October to December 2026 quarter, as notified by the government for small savings schemes. Bank RD rates vary by bank and tenure, so check your bank’s current rate card before opening one.
Bank deposits are insured by the Deposit Insurance and Credit Guarantee Corporation (DICGC) up to Rs 5 lakh per depositor per bank, covering principal and interest together. Post office schemes are backed by the Government of India.
How a SIP works
A systematic investment plan (SIP) is a way to invest a fixed amount in a mutual fund every month. Each instalment buys units at that day’s net asset value (NAV). When prices are low you get more units, and when prices are high you get fewer.
There is no fixed return. What you earn depends on the fund you choose. An equity fund follows the stock market, while a debt fund invests in bonds and money market instruments and moves less sharply. You can see how different monthly amounts and return assumptions play out with a mutual fund SIP calculator.
RD vs SIP: quick comparison
| Feature | Recurring deposit | Equity mutual fund SIP |
|---|---|---|
| Returns | Fixed, known at the start | Market-linked, not guaranteed |
| Risk to capital | Very low; DICGC cover up to Rs 5 lakh per bank | Value can fall, sometimes sharply |
| Tax on gains | Interest taxed at your slab rate every year | 12.5% LTCG above Rs 1.25 lakh a year; 20% STCG |
| TDS | 10% if interest crosses the threshold | No TDS for resident individuals on capital gains |
| Early exit | Allowed with a lower rate or penalty | Redeem any working day; exit load may apply |
| Missed payment | Bank may charge a penalty | SIP may be cancelled after repeated failures; no fixed penalty from the fund |
How RD interest is taxed
RD interest is added to your income and taxed at your slab rate under the “income from other sources” head. This applies whether you pick the old or new tax regime. Interest is taxable every year as it accrues, not just in the year of maturity.
Banks deduct TDS at 10% on interest if the total interest from that bank in a financial year exceeds Rs 50,000, or Rs 1 lakh for senior citizens. These limits were raised in Budget 2025 and carried into the Income-tax Act, 2025, which took effect on 1 April 2026. TDS is not the final tax. If you are in the 20% or 30% bracket, you pay the balance when you file your return.
If your total income is below the taxable limit, you can submit the self-declaration form to your bank so that no TDS is deducted. For more on how deposit interest is handled, see our explainer on tax implications of fixed deposits, which follow the same rules.
How mutual fund SIP gains are taxed
Mutual fund taxation changed on 23 July 2024 and Union Budget 2026 left the rates unchanged. The current position is as follows.
Equity funds
- Short-term capital gains (units held 12 months or less): taxed at 20%.
- Long-term capital gains (units held more than 12 months): taxed at 12.5% on gains above Rs 1.25 lakh in a financial year.
- These rates apply to equity-oriented funds, which hold at least 65% in Indian equity shares.
Debt funds
- Units bought on or after 1 April 2023 are taxed at your slab rate, no matter how long you hold them. There is no indexation benefit.
- This makes a debt fund SIP similar to an RD on tax for most people. The case for a debt fund then rests on liquidity and the timing of tax, since gains are taxed only on redemption rather than every year.
One detail matters for SIPs. Each instalment is treated as a separate purchase, and the holding period counts from that instalment’s date. If you redeem the whole SIP after five years, units bought in the last 12 months are short-term. Those gains are taxed at 20%, even though the rest qualify as long-term.
Worked example: Rs 10,000 a month for 5 years
The figures below are illustrations, not predictions. They use the following assumptions.
- Monthly saving: Rs 10,000 for 60 months, a total of Rs 6,00,000.
- RD rate: 6.7% a year compounded quarterly, the Post Office 5-year RD rate for October to December 2026.
- Equity SIP returns: three assumed annual rates of 0%, 6% and 10%. Past returns of any fund do not guarantee these.
- All units sold in one go at the end of month 60, with no other capital gains that year.
- Tax includes 4% health and education cess. Surcharge and exit loads are ignored.
- RD tax is shown for an investor in the 30% slab and one in the 20% slab.
| Option | Value at maturity | Gain | Approx. tax | Post-tax value |
|---|---|---|---|---|
| RD at 6.7%, 30% slab | Rs 7,13,658 | Rs 1,13,658 | Rs 35,461 | Rs 6,78,197 |
| RD at 6.7%, 20% slab | Rs 7,13,658 | Rs 1,13,658 | Rs 23,641 | Rs 6,90,017 |
| Equity SIP, 0% a year | Rs 6,00,000 | Nil | Nil | Rs 6,00,000 |
| Equity SIP, 6% a year | Rs 6,98,240 | Rs 98,240 | Rs 804 | Rs 6,97,436 |
| Equity SIP, 10% a year | Rs 7,71,717 | Rs 1,71,717 | Rs 6,573 | Rs 7,65,145 |
Two points stand out. First, even at a modest 6%, the equity SIP ends up close to the RD after tax for someone in the 30% slab, because most of the SIP gain falls within the Rs 1.25 lakh exemption. Second, in a flat or falling market, the SIP can end below the RD, and in a bad year it can end below the amount you put in. The RD figure, on the other hand, is known on day one.
Over three years, the gap narrows further. With the same Rs 10,000 a month, the RD at 6.7% would mature at about Rs 3,99,492, while an equity SIP would need an annual return of roughly 7% or more just to match it before tax. Three years is a short time for equity markets, and a single correction near the end can wipe out the extra return.
Risk and liquidity
RD risk: The main risk is that inflation eats into the real return, especially after tax. The nominal amount is safe, subject to the DICGC limit for banks.
SIP risk: Equity funds can see deep falls. Sequence risk is the bigger worry for short goals. If markets drop in the last year, there is little time to recover. Debt funds carry interest rate risk and credit risk, though usually much smaller swings than equity.
RD liquidity: Banks allow premature closure, usually at a lower interest rate than the one you booked, sometimes with a further penalty. The Post Office RD allows premature closure only after three years, and then pays the post office savings account rate instead of the RD rate. It also offers a loan of up to 50% of the balance after 12 instalments.
SIP liquidity: You can stop the SIP or redeem units on any working day. Many equity funds charge an exit load, commonly 1% if units are sold within a year, but this varies by scheme, so check the scheme information document.
Which should you pick for a 3 to 5 year goal?
There is no single answer, but the following rules of thumb are practical.
- Pick an RD if the goal has a fixed date and a fixed amount that cannot move, such as a school fee, a down payment due on a set date, or a wedding with booked venues. Certainty matters more than extra return here.
- Pick an RD if you are in a low or nil tax bracket, since the slab-rate tax on interest then costs little.
- Consider an equity SIP if the goal is closer to five years than three, the date is flexible, and you can delay the goal by a year or two if markets fall.
- Consider a mix if you want some growth with a safety net, for example part in an RD and part in a hybrid or equity fund.
- Move money out of equity early. If you use an equity SIP, start shifting the accumulated amount to a deposit or liquid fund 12 to 18 months before the goal date to lock in gains.
Whichever you choose, set the monthly debit for the day after your salary credit. Our guide on automating your savings account explains how to set this up.
Frequently asked questions
Is SIP better than RD for 5 years?
An equity SIP has a better chance of beating an RD over five years, and its tax is lower for most people. But returns are not guaranteed, so an RD is safer when the amount must be available on a fixed date.
Is RD interest taxable?
Yes. RD interest is added to your income and taxed at your slab rate every year. Banks deduct 10% TDS if interest from that bank crosses Rs 50,000 in a year, or Rs 1 lakh for senior citizens.
What is the tax on SIP returns after 1 year?
For equity funds, gains on units held over 12 months are taxed at 12.5%, and only on gains above Rs 1.25 lakh in a financial year. Gains on units held 12 months or less are taxed at 20%.
Can I lose money in a SIP?
Yes. Mutual fund values move with the market, and over three to five years an equity SIP can end below the total amount invested if markets fall near the end.
Can I break an RD before maturity?
Banks allow it, usually at a reduced rate. A Post Office RD can be closed early only after three years, and earns the savings account rate in that case.
