Published: 2026-10-21 Updated: 2026-10-21 Vikram's father has put Rs 5,000 into a recurring deposit every month for as long as Vikram can remember, and he's never once asked what a mutual fund is. Vikram, 26 and just starting his first job, wants the same discipline but keeps hearing that an SIP would grow his money faster. Both of them are right, up to a point, and the actual rupee difference between the two is worth working out before picking either one. This is a straight comparison for conservative investors in India deciding between a bank recurring deposit and an equity mutual fund SIP for the same monthly amount and the same time horizon, the kind of decision an RD calculator can settle with real numbers instead of gut feel. ## What is a recurring deposit, and how is it different from an SIP?[ #](#what-is-a-recurring-deposit-and-how-is-it-different-from-an-sip) A recurring deposit (RD) is a fixed-income product offered by banks and post offices where you deposit a fixed amount every month for a chosen tenure, and the bank pays a fixed, guaranteed interest rate, compounded quarterly. The return is locked in the day you open the account, whatever happens to markets or interest rates afterward. A systematic investment plan (SIP) is a fixed monthly investment into a mutual fund, usually an equity fund for long-term goals. Unlike an RD, the return isn't fixed, it depends on how the underlying market performs, which means it can beat an RD by a wide margin in good years and underperform it, even turn negative, in bad ones. ## How the numbers are actually calculated[ #](#how-the-numbers-are-actually-calculated) An RD's maturity value is calculated using the standard quarterly-compounding formula banks use: each monthly instalment earns interest for the remaining quarters until maturity, based on the annual interest rate divided across four quarters a year. A 6.5% RD rate and a 6.5% fixed deposit rate produce nearly identical returns, since both are simple compound interest on a fixed rate. An SIP's maturity value uses a different formula built around a monthly rate of return applied to a growing corpus: each instalment compounds for the remaining months at the assumed annual rate of return, typically modelled at 10% to 12% for a diversified equity fund over the long term, though this is an assumption, not a guarantee, the way a bank's RD rate is. ## Worked example: Rs 5,000 a month for 5 years[ #](#worked-example-rs-5000-a-month-for-5-years) Put Rs 5,000 a month into an RD at 6.5% annual interest for 5 years (60 months), and the maturity value comes to roughly Rs 3,54,954, of which Rs 3,00,000 is your own deposits and about Rs 54,954 is interest. Put the same Rs 5,000 a month into an equity SIP assumed to grow at 12% a year for the same 5 years, and the maturity value comes to roughly Rs 4,12,432, with the same Rs 3,00,000 invested and about Rs 1,12,432 in returns. That's a gap of roughly Rs 57,500 over five years in favour of the SIP, assuming the 12% return actually materialises. The RD's number, by contrast, is close to guaranteed the day you open the account, the only real uncertainty is whether the bank itself stays solvent, which is why RDs are insured up to Rs 5,00,000 per depositor per bank under DICGC cover. ## When an RD makes more sense than an SIP[ #](#when-an-rd-makes-more-sense-than-an-sip) An RD is the better tool when the money has a fixed, non-negotiable deadline within the next one to three years, a wedding, a planned down payment, or school fees due next year, because you cannot afford a market downturn eating into the amount right before you need it. It's also the right choice for anyone who genuinely cannot stomach seeing their balance fall, since panic-selling an SIP during a downturn often does more damage than a lower guaranteed RD return ever would. An SIP earns its place when the goal is at least five to seven years away, giving equity markets enough time to recover from any downturns along the way, and when the investor can leave the money alone during volatile periods rather than reacting to short-term swings. ## Common mistakes people make choosing between the two[ #](#common-mistakes-people-make-choosing-between-the-two) **Mistake 1: Comparing an RD's guaranteed rate directly to an SIP's assumed rate as if they carry the same risk.** A 6.5% RD return is contractually guaranteed; a 12% SIP assumption is a long-term historical average that any single 5-year window can miss by a wide margin, in either direction. **Mistake 2: Using an SIP for a goal less than three years away.** Equity markets can fall 20% or more in a bad year, and a short horizon doesn't give the portfolio time to recover before you need the money, turning what should be a safe short-term goal into a gamble. **Mistake 3: Treating an RD as a long-term wealth-building tool.** Over 15 or 20 years, the gap between a fixed 6% to 7% RD return and a long-term equity return compounds into a very large difference, RDs are built for capital safety and short-term certainty, not for outpacing inflation over decades. ## Tips for using each one well[ #](#tips-for-using-each-one-well) Split your monthly savings instead of picking just one: route the portion earmarked for goals under three years into an RD or fixed deposit, and the portion for goals five years or further out into an SIP. Ladder your RDs across a few different maturities if you're saving for several near-term goals, so you're not forced to break one large RD early and lose accrued interest for a smaller, unrelated need. Review your SIP's underlying fund performance annually against its benchmark, not against the RD, an SIP should be judged over its own multi-year horizon, not compared to a fixed-income product month to month. ## Internal links to run your own numbers[ #](#internal-links-to-run-your-own-numbers) Compare your specific monthly amount and tenure using the [RD calculator](/rd-calculator), including a preset scenario like [Rs 5,000 a month for 36 months](/rd-calculator/5000-monthly-36-months), against the [SIP calculator](/sip-calculator) for the equity side of the comparison.

RDs also carry DICGC deposit insurance up to Rs 5,00,000 per bank. ### Can I withdraw an RD or SIP before the tenure ends?[ #](#can-i-withdraw-an-rd-or-sip-before-the-tenure-ends) Both allow early exit, but with different costs. Breaking an RD early usually means the bank pays a lower interest rate for the period it was actually held, while redeeming an SIP's equity fund units may attract short-term capital gains tax if held under a year, along with any exit load the fund charges. ### Which gives better returns, RD or SIP, over 10 years?[ #](#which-gives-better-returns-rd-or-sip-over-10-years) Historically, a well-diversified equity SIP has outperformed RD returns over 10-year periods, but this isn't guaranteed for any specific decade, and the outcome depends heavily on which years the market rose or fell during. RDs offer certainty, SIPs offer a higher expected return with real variability. ### Is RD interest taxable?[ #](#is-rd-interest-taxable) Yes, RD interest is fully taxable as income from other sources at your applicable income tax slab rate, and banks deduct TDS if the interest earned crosses the threshold in a financial year. SIP gains in equity funds, by contrast, are taxed as capital gains, at different rates depending on the holding period. ### Should a conservative investor avoid SIPs entirely?[ #](#should-a-conservative-investor-avoid-sips-entirely) Not necessarily, a conservative investor can still run a small SIP allocation, often into a debt or hybrid mutual fund rather than a pure equity fund, to get exposure to potentially higher returns while keeping volatility lower than an all-equity portfolio. The right mix depends on your goal timeline and how much fluctuation you can tolerate. ## The bottom line[ #](#the-bottom-line) An RD and an SIP aren't really competing for the same job, one guarantees a modest return for money you can't risk losing, the other offers a higher expected return for money you can leave alone for years. Run both scenarios on the [RD calculator](/rd-calculator) and the [SIP calculator](/sip-calculator) for your own amount and timeline, and let the goal's deadline, not which one sounds more exciting, decide where your next Rs 5,000 goes.
