SIP vs FD: Which Is Better for You in 2026?

The short answer: SIP vs FD

If you can stay invested for 5 years or more, a SIP in an equity mutual fund has historically had the better chance of beating a fixed deposit, and of beating inflation. If you need the money in under 3 years, or you cannot bear to see your balance fall, an FD is the safer choice.

That is the whole decision in two lines. The rest of this guide shows the numbers behind it: returns, risk, tax, liquidity and a simple way to split your money between the two. You can check every figure in our free SIP calculator and FD calculator.

SIP vs FD at a glance

One thing is worth saying early: SIP and FD are not the same kind of thing. A SIP is a way of investing (a fixed amount, every month). An FD is a product (a deposit with a bank). The fair comparison is therefore a SIP in an equity fund against a monthly deposit in an FD or recurring deposit (RD).

Returns: ₹10,000 a month in a SIP vs an RD

Say you invest ₹10,000 every month. We assume 12% a year for the equity SIP and 7% a year for the bank deposit. These are not promises, just reasonable long-term assumptions:

Look at the gap. After 5 years the two are close, with ₹1.06 lakh between them. After 20 years the SIP is almost double the deposit. The reason is compounding: a higher rate matters more and more as the corpus gets bigger. You can try your own amount in the RD calculator and the SIP calculator.

Returns on a lump sum: ₹10 lakh in an FD vs equity

For a lump sum, here is ₹10 lakh in a 7% FD compared with an equity fund at 12%, and at a weaker 8%:

Even the weak 8% case stays ahead of the FD, but only slightly. Compare your own amount with the lumpsum calculator.

Risk: the price you pay for higher returns

The higher return of a SIP is not free. Equity fund values rise and fall with the market, and a fall of 20–30% in a bad year is normal. Nobody can tell you in advance which years those will be.

Take a bad 5-year patch. If your SIP earned only 3% a year, your ₹6 lakh would grow to about ₹6.48 lakh. A 7% RD would have given you ₹7.19 lakh. In that case, the safe option clearly wins. The good news is that this risk shrinks with time. In our calculations, a SIP only needs to earn about 7% a year to match a 7% RD. Over 10 to 20 years, equity has usually done better than that, though it is never guaranteed.

Tax: what you actually keep

Tax is where many people get a surprise. FD interest is taxed every year at your slab rate, even if you do not withdraw it. For someone in the 30% slab, a 7% FD earns only about 4.9% a year after tax (including 4% cess). Banks also deduct TDS at 10% once interest crosses ₹50,000 a year (check it in our TDS calculator).

Equity mutual funds are taxed only when you sell. At the time of writing, gains on units held for more than 12 months are taxed at 12.5% above ₹1.25 lakh of gains in a financial year. Units sold within 12 months are taxed at 20%. Tax rules change, so check the latest ones.

After tax, the RD's 20-year result falls from ₹52.14 lakh to ₹40.31 lakh, while the SIP drops from ₹99.91 lakh to ₹90.21 lakh. In other words, tax hurts FD savers far more. If you earn less and fall in a lower slab, the gap is smaller. You can see your slab in the income tax calculator.

Inflation: the quiet problem with FDs

With inflation at about 6%, a 7% FD looks like it gives you a 1% real return. After tax, that turns negative. A 4.9% after-tax return against 6% inflation means your money loses about 1% of buying power every year.

In both cases the FD ends up with less buying power than the ₹10 lakh you started with. It kept your rupees safe, but not their value. To see this effect for your own goal, try the inflation calculator.

Which one should you choose? A guide by goal

You do not have to pick one

Most people do best with both. The FD is your safety net and the SIP is your growth engine. A simple plan:

1. Build an emergency fund first. Park 6 months of expenses in an FD or a savings account.
2. Start a SIP for your long-term goals. Even ₹2,000–₹5,000 a month is a good start.
3. Raise your SIP every year. A 5–10% yearly step-up keeps pace with your income. See how much it helps in the SIP calculator.
4. Use FDs or RDs for short-term goals. Anything due within 3 years belongs here.
5. Review once a year. Check your goals, tax slab and FD rates.
