SIP vs FD vs RD: Where Should a Beginner Put ₹5,000 a Month?

You have ₹5,000 a month you can genuinely spare. Three products compete for it, and every relative has a strong opinion about which one. This guide runs all three over the same ten years with the same money, before and after tax, and then says plainly which is right for which situation.

What the three products actually are

A recurring deposit is a bank product where you commit to depositing a fixed sum every month for a fixed tenure at a rate locked in on day one. It compounds quarterly like an FD. Large banks are quoting roughly 6.5% to 7% on RDs as of September 2026; check your own bank's card rate.

A fixed deposit takes a lump sum for a fixed period. With ₹5,000 a month you cannot open one every month sensibly, so the realistic version is to accumulate the money and book a fresh deposit once a year, or to use a sweep-in account that converts surplus balance into FDs automatically.

A SIP is not a product at all — it is a standing instruction to buy units of a mutual fund every month. The return is whatever the fund earns, which for a diversified equity fund has historically averaged around 12% a year over long periods but is not guaranteed and can be negative for years at a stretch.

Head-to-head comparison

₹5,000 a month for ten years

Same ₹5,000, same 120 months, ₹6,00,000 contributed in every case. Realistic rates: 12% for a diversified equity fund, 6.75% for an RD, and 7% for the FD version, where each year's ₹60,000 goes into a fresh deposit that runs to the end of year ten.

The SIP produces about ₹3 lakh more than either deposit. That gap is the reward for accepting risk, and it is worth being honest about what the risk means: over those ten years the SIP value would have fallen below the amount invested at some point, possibly for a year or more, while the RD balance would have gone up every single quarter without exception.

Also note the FD ladder trails the RD slightly here despite a higher headline rate. That is not a quirk of the products — it is because in the ladder, ten months of each year's money sits idle in a savings account before the deposit is booked. Money that is not invested does not compound.

If you want a more conservative equity assumption, run the SIP at 10% instead of 12% and the corpus is ₹10,32,760 — still ahead of both deposits, but by ₹1.8 lakh rather than ₹3 lakh. You can try other numbers in our SIP calculator and FD calculator.

What tax does to the answer

The pre-tax comparison understates the gap, because deposit interest and equity gains are taxed very differently.

FD and RD interest is added to your total income and taxed at your slab rate. For someone in the 30% bracket that is 31.2% including cess. Worse, the tax is due every year on interest that has accrued, even though a cumulative deposit pays out only at maturity. Banks deduct 10% TDS under Section 194A once interest at that bank crosses ₹50,000 in a year, or ₹1,00,000 for senior citizens, and you settle the rest when filing.

Equity mutual fund gains held for more than twelve months are long-term, taxed at 12.5% on the amount above a ₹1,25,000 annual exemption, and nothing is payable until you actually redeem. Units held twelve months or less are taxed at 20%.

After tax the SIP is ahead by ₹3.3 lakh rather than ₹3 lakh. The deposit options lose about a third of their gain to tax; the SIP loses under a tenth, because most of its gain sits under the long-term rate and part of it inside the annual exemption. Redeeming in tranches across financial years, so that each year's gain stays near ₹1.25 lakh, can reduce the tax further.

One caveat that cuts the other way: if your total income is below the taxable limit, FD and RD interest is effectively tax-free for you and the deposit options look considerably better than this table suggests.

Who each one suits

A recurring deposit suits you if the money has a date on it within the next one to three years — a wedding, a bike, an insurance premium, a semester fee. It also suits anyone who has never saved regularly before, because the monthly commitment builds the habit and the balance never falls, which matters more psychologically than most advisers admit.

A fixed deposit suits you if you already have a lump sum rather than a monthly surplus, or if you are building an emergency fund and want the money reachable within a day. It is also the right home for money you will need at a known date inside five years, where a market fall in the wrong month would be genuinely damaging.

A SIP suits you if the horizon is seven years or longer and you can tolerate seeing the balance fall. Retirement, a child's higher education fifteen years out, or simply long-term wealth building. The critical requirement is behavioural, not financial: you must not stop the SIP during a market fall, which is exactly when it buys the most units.

A suggested split

For most people starting out with ₹5,000 a month, splitting beats choosing. A sequence that works:

1. Months 1 to 12 — build the base. Put ₹3,000 into an RD or a liquid fund and ₹2,000 into an equity index SIP. By the end of the year you have roughly ₹37,000 of accessible savings plus a started investment habit.
2. Once you have three to six months of expenses saved, flip the ratio: ₹1,000 to the RD and ₹4,000 to the SIP. The emergency fund is done; the rest should compound.
3. From year three onward, register a 10% annual step-up on the SIP. A flat ₹4,000 SIP at 12% for twenty years is worth about ₹39,96,592; stepping it up 10% a year takes it to roughly ₹79,55,486, because your contribution grows with your salary.

Two practical notes. Buy the direct plan of any mutual fund, not the regular plan — the expense ratio difference of roughly 1.2 percentage points compounds into lakhs over a decade. And keep it simple: one broad index fund or one flexi-cap fund is enough at ₹5,000 a month. Splitting ₹5,000 across five schemes adds paperwork, not diversification.

Finally, if you have a home loan, compare all of this against prepaying it. At 8.5% a prepayment is a guaranteed return that beats every deposit on this page after tax. Our guide on closing a home loan early runs those numbers.
