SIP vs FD: Where Should Your Money Go? Returns, Tax and Risk

Ask ten people at a family function where to put your savings and you will get two camps. The elders say FD, because the bank has never let them down. The cousin who works in Bengaluru says SIP, because "FD doesn't even beat inflation". Both are partly right. The real answer depends on when you need the money, which tax slab you are in, and how you would feel if your balance dropped 25% in a bad year.

So let's go through it properly: how each one earns, what can go wrong, what tax does to the returns, and what it all looks like in rupees. Every example below comes from the calculators on this site, so you can redo them with your own numbers.

FD and SIP in plain words

A fixed deposit is basically a loan you give the bank. You hand over, say, ₹1 lakh for five years, the bank promises a rate, and at the end you get your money back with interest. The rate is locked on the day you open it. Whatever happens to rates after that, your FD doesn't care.

A SIP (systematic investment plan) is not a product. It is a way of buying mutual fund units: a fixed amount leaves your account every month, usually a few days after salary credit, and buys units at that day's price. When people say "SIP vs FD" they almost always mean a SIP in an equity mutual fund, so that's what we compare here.

On the bank side, the closest cousin of a SIP is the recurring deposit (RD): fixed amount every month, fixed rate, fixed maturity. We'll put those two head to head further down.

How the returns actually work

FD returns are contractual. Big banks are paying roughly 6–6.5% a year for one to five years right now (SBI's card rate for 5–10 years is 6.05%, for example), and small finance banks go up to around 7–8%. Senior citizens usually get about 0.5% extra. Most banks compound quarterly, so 6.5% actually works out to 6.66% a year. RBI raised the repo rate in its October 2026 policy, which means FD rates may inch up in the coming months. Check the bank's current rate card before you book.

SIP returns are whatever the market gives. There is no rate. Your units move every day with the NAV. Over long stretches, diversified equity funds in India have often given something like 10–12% a year, but that is history, not a promise, and there have been five-year stretches with much lower returns. The examples here use 10% and 12% as assumptions. If you want to be careful, plan with 10%.

Risk: what can actually go wrong

With an FD, the main risk is the bank itself. Big banks going under is rare, but co-operative bank and small bank scares do happen, and when they do, withdrawals get frozen. Your safety net is deposit insurance. As of now, DICGC insures up to ₹5 lakh per depositor per bank, and that limit covers principal and interest together. It applies to commercial banks (small finance banks included) and co-operative banks. There has been talk of raising the limit, so check DICGC's site if you are close to it. In practice: if you are chasing 8% at a small finance bank, keep principal plus interest there under ₹5 lakh and spread the rest across banks.

The quieter FD risk is losing to inflation and tax. More on that below.

With a SIP, the risk is printed on every fund's factsheet. SEBI makes each scheme show a riskometer with six levels, from Low to Very High, reviewed every month, and nearly all equity funds sit at "Very High". That line at the end of every ad, "mutual fund investments are subject to market risks", means exactly this: the value can fall and nobody makes up the loss. In 2008 and again in March 2020, equity values dropped by a third or more within months. Anyone who needed the money that year had to sell at a loss.

What softens equity risk is time. Over one year, anything can happen. Over ten, bad years have historically been made up by good ones, though past patterns are not a guarantee. A SIP helps a bit on its own too, because when prices fall your ₹5,000 buys more units.

Getting your money out: liquidity and lock-ins

Both are more liquid than people assume.

You can break most FDs any day. The catch is the penalty: most banks cut the rate by 0.5–1% for premature closure, and you get the rate for the period the money actually stayed, not the one you booked. A neat way around this is to split a big FD into smaller ones (₹5 lakh as five FDs of ₹1 lakh). Need ₹1 lakh? Break one, leave the rest alone.

The exception is the tax-saver FD: a hard five-year lock-in, no premature withdrawal, no loan against it. The 80C deduction (section 123 under the new Income-tax Act) only helps if you are in the old regime, and the interest is still fully taxable.

Mutual fund units can be sold on any working day, and the money usually reaches your bank within a few working days. Some equity funds charge an exit load if you sell early, often around 1% within the first year. It differs from fund to fund, so read the scheme details. SEBI's investor site explains exit loads in simple terms.

The equity version of the tax-saver FD is an ELSS fund: three-year lock-in, same 80C benefit in the old regime. With an ELSS SIP, each instalment has its own lock-in, so your January 2027 instalment is free in January 2030, February's in February 2030, and so on.

The real liquidity problem with a SIP isn't the rules. It's that the money may be down exactly when you need it. That's why emergency money doesn't belong in equity.

The numbers: SIP vs RD, and lumpsum vs FD

₹5,000 a month

Say you can set aside ₹5,000 every month. Here is an RD at 6.5% against an equity SIP at an assumed 10% and 12%, before tax.

Look at how the gap grows. At five years the SIP is ahead by about ₹35,000 to ₹57,000, not much extra for the extra risk. At fifteen years it is ahead by ₹5.7 lakh to ₹10 lakh. Compounding needs time, and five years is short for equity.

You can check every row on the SIP calculator and the RD calculator. (The RD calculator stops at 10 years, so for 15 we rolled the 10-year maturity into a 5-year FD at the same rate and added a fresh 5-year RD. Same answer as one long RD.)

For a safe 15-year comparison, PPF is fairer. ₹60,000 a year at 7.1% for 15 years comes to about ₹16.27 lakh on the PPF calculator, and that interest is tax-free.

₹1 lakh one time

Now say you have ₹1 lakh lying idle, maybe a Diwali bonus, for five years. In an FD at 6.5% it becomes ₹1,38,042 on the FD calculator. A small finance bank FD at 7.5% would give ₹1,44,995. Put it in an equity fund in one go and, at an assumed 12%, the lumpsum calculator shows ₹1,76,234. At 10%, ₹1,61,051.

So before tax the equity side looks ₹23,000 to ₹38,000 better than the 6.5% FD. But a lumpsum carries timing risk that a SIP doesn't. If the market falls 20% the month after you invest, you start the five years in a hole. For a big amount, many people park it in a liquid fund and shift it into equity over 6–12 months (an STP) instead of going all in on one day.

Tax: where the real gap opens up

Most SIP vs FD comparisons skip this part. If you are in a higher slab, it changes everything.

FD and RD interest is added to your income and taxed at your slab rate, every year as it accrues, even on a cumulative FD where you see nothing till maturity. No special rate, no exemption. Banks deduct 10% TDS once your interest from that one bank crosses ₹50,000 in a tax year, or ₹1 lakh for senior citizens (section 393 of the Income-tax Act, 2025). Without PAN it's 20%. Two things people get wrong. TDS is not your final tax: in the 30% slab, the bank cuts 10% and you pay the rest at ITR time. And splitting FDs across banks to stay under the limit avoids TDS, not tax.

If your tax for the year works out to nil, you can give the bank Form 121 so it doesn't deduct TDS. It replaced Forms 15G and 15H from 1 April 2026. Seniors only need their tax to be nil; those below 60 also need their interest and similar income to stay within the basic exemption limit. The Income Tax Department's Form 121 FAQs have the details. Submit it at the start of every tax year, before the first interest credit. TDS already cut is not refunded by the bank, so you'd have to claim it back in your ITR.

Equity mutual funds are taxed only when you sell, and at lower rates. Held 12 months or less: short-term gain, 20%. Held longer: long-term gain, 12.5%, with the first ₹1.25 lakh of long-term gains in a year exempt (section 198 of the new Act). Budget 2026 left these unchanged. Add 4% cess on top, as always. In a SIP, every instalment has its own holding period, so if you sell everything after ten years, the last twelve instalments still count as short-term.

Debt funds are no longer a tax-smart FD. For units bought from 1 April 2023, gains are taxed at your slab rate whatever the holding period, the same as FD interest. The only difference left is that you pay when you sell, not every year.

What this does to the ₹1 lakh example

Take someone in the 30% slab (above ₹24 lakh income in the new regime, above ₹10 lakh in the old). With cess, that's 31.2% on every rupee of FD interest.

In other words, a 6.5% FD earns a 30% slab taxpayer about 4.5% a year after tax. Same maths for ₹5,000 a month over 10 years: the RD's ₹2,44,940 of interest costs ₹76,421 in tax, leaving ₹7,68,519. The SIP at 12%, sold in one go at the end, owes about ₹57,000 (₹56,244 on long-term gains above ₹1.25 lakh plus ₹842 on the last year's short-term gains), leaving about ₹11.05 lakh. Spread the selling over two tax years and you get the ₹1.25 lakh exemption twice.

In a low slab, or with no tax at all after the rebate, the FD's tax handicap mostly goes away. Check where your interest actually lands on the income tax calculator.

Inflation and real returns

Retail inflation was 4.82% in August 2026, as per MoSPI's CPI release, and RBI expects a little over 5% for the year. For long-term planning most people take 5–6%. Your own household inflation, with school fees and medical bills, is often higher.

Your "real" return is roughly the return minus inflation. A 6.5% FD against 5% inflation leaves about 1.5% of real growth before tax. After tax in the 30% slab, it's slightly negative. That's the last row of the table above: ₹1 lakh becomes ₹1,26,173 after tax, which buys about what ₹98,860 buys today. Take inflation at 6% and it's closer to ₹94,284. The money didn't shrink, but it didn't grow either.

This is the strongest case for equity over long periods. An FD keeps your money safe in rupees, not always in what those rupees can buy. For a goal like retirement 25 years away, that difference is massive. The retirement calculator shows how fast monthly expenses grow at 6% inflation.

Who should pick what

Forget "which is better". Ask "when do I need this money?"

• Within 1–3 years (house down payment, a wedding, a car): FD or RD. Equity can be down 20% right when you need it, with no time to recover.
• 3–5 years: grey zone. Use a mix, with more in FD or RD the closer the goal is. Don't go all-equity for a five-year goal you can't shift.
• 5 years and beyond (child's education, retirement): SIP makes more sense as the base. Time does the heavy lifting.
• Emergency fund: FD, sweep-in FD or savings account, always. Keep about six months of expenses there before starting any SIP. A job loss or hospital bill won't wait for the market to recover.
• 20s or 30s with a salary: most long-term money can go into SIPs. You have decades, and a regular income to sit through bad years.
• Senior citizens: steady income matters more than growth. FDs (senior rate, ₹1 lakh TDS limit) and the Senior Citizens' Savings Scheme (8.2% for October–December 2026) suit most of the money. But retirement can run 25 years or more, so a modest equity portion helps the corpus keep up with prices. Some retirees draw from that part through an SWP; the SWP calculator shows how long such a payout lasts.
• Low or nil tax slab: FDs look better for you than the averages suggest. Inflation still applies, though.

Using both together

For most families it isn't one or the other. It's a split by goal:

1. Emergency fund first, in FDs or a sweep-in account. About six months of expenses.
2. Anything needed within three years goes into FDs, or an RD timed to the goal. Saving for something 18 months away? An 18-month RD fits nicely.
3. Money for goals five years or more away goes into SIPs.
4. When a long-term goal is two or three years off, start shifting that money from equity to FD bit by bit, so a late crash can't spoil it.

Say you save ₹20,000 a month. Early on, maybe ₹10,000 goes to an RD till the emergency fund is built and ₹10,000 to SIPs. Once that's done, most of it can move to SIPs, with RDs only for near-term goals.

The habit that makes the biggest difference is a step-up SIP: raise it every year with your increment. ₹5,000 a month, flat, for 15 years at an assumed 12% grows to ₹25.23 lakh. Raise it by 10% every year and it grows to ₹43.42 lakh. You put in ₹19.06 lakh in total, and your monthly SIP in the last year is about ₹18,987. Do the step-up right after appraisal season and you hardly feel it.

Mistakes to avoid, and a quick checklist

• Comparing a fixed rate with a best-case one. An FD's 6.5% is certain. A fund's "18% last year" is not a rate at all. Compare with a modest 10–12% long-term assumption, and know it can come in lower.
• Stopping the SIP when markets fall, or judging it after one year. A falling month is when your money buys the most units, and one red year means nothing for equity.
• Forgetting FD tax. 10% TDS doesn't settle a 30% slab. Banks report your interest to the tax department (it shows in your AIS), so leaving it out of your ITR is asking for a notice.
• Emergency money in equity. Or the opposite: 20 years of retirement savings sitting in FDs, quietly losing to inflation.
• More than ₹5 lakh in one small bank for an extra 1%. Spread it out.
• "Better than FD" pitches. Insurance-cum-savings plans sold as FD alternatives often work out to much less than they sound. Ask for the actual yearly return (the IRR), in writing.

Before you decide

1. When exactly do I need this money? Under 3 years: FD or RD. Over 5 years: SIP.
2. Do I already have six months of expenses in safe, easy-to-reach money?
3. What is my slab? At 30%, FD interest loses almost a third to tax.
4. If this fell 25% next year, would I hold on or panic-sell?
5. Does any one bank hold more than ₹5 lakh of mine, interest included?
6. Can I raise my SIP when my salary goes up?

Answer the first one honestly and the rest usually falls into place.
