How much do I need to start?

₹500 a month into an index fund SIP. That is not a motivational figure — ₹500 a month for 20 years at 12% is about ₹5 lakh. The amount matters far less than the start date, which is why the delay calculator above is the most important thing on this page.

Buying a stock because someone recommended it and selling it three weeks later is gambling, and it is what most beginners do. Owning the 50 largest listed companies in a growing economy for twenty years is not. The instrument is the same; the holding period and the research are what differ.

NSE or BSE — does it matter which?

No. Both are regulated by SEBI, both settle T+1, and almost every large company is listed on both. NSE has the higher volume, so large orders fill marginally better there. For a beginner buying index funds, the question never comes up.

Individual stocks or mutual funds?

Funds, until you can read a balance sheet and explain in one paragraph why a business will earn more in five years than it does now. That is not gatekeeping — it is that a single index fund gives you 50 companies for 0.2% a year, and beating that with your own picks is genuinely hard work.

What do I pay in tax?

Under the rules in force since 23 July 2024: gains on listed shares held over 12 months are long-term, taxed at 12.5% on the amount above a ₹1.25 lakh annual exemption. Held 12 months or less, gains are short-term and taxed at 20%. Dividends are added to your income and taxed at your slab rate — they have not been tax-free since FY 2020-21. Rates change with each Budget, so check the current year before you file.

Stock Market Basics

₹50Lwhat ₹5,000 a month becomes in 20 years

You invest ₹12 lakh of your own money — ₹5,000 a month, for twenty years. You end up with roughly ₹50 lakh. The other ₹38 lakh was not earned at a job and nobody paid it to you. It came from owning parts of companies while they grew.

That is the entire proposition. Everything below is mechanics.

When you buy one share of a listed company, you own a fraction of the whole business — its factories, its brand, its cash, and its profits. If the company earns more next year than this year, your fraction is worth more. If it earns less, it is worth less.

Everything else — the ticker, the chart, the man shouting on television — is machinery around that one fact.

A company sells shares once, to raise money. After that, shares change hands between investors and the company gets nothing further. This is why "the market" and "the economy" can move in opposite directions for years at a stretch.

Compounding is not a concept. It is a number you can move.

Drag the sliders. Watch what changes and — more importantly — what does not.

Move these. Watch the last number.

Every month you invest₹5,000

You keep going for20 years

You put in ₹12,00,000. At 12% a year you end up with

₹49,95,740

₹37,95,740 of that — 76% of the final pile — is money you never earned at a job. Nobody paid it to you. It came from the 20 years.

What it became What you paid in

Notice that doubling the monthly amount doubles the result, while adding ten years to the horizon does far more than that. Time is the input that matters, and it is the one you cannot buy later.

Waiting is the most expensive thing you will ever do

The cost of starting later

You start investing at age25

Starting at 25, ₹5,000 a month until 60 becomes ₹3,24,76,345. Drag the slider to see what each year of waiting costs.

Starting at 25 against starting at 32

Start at 25, invest until 60₹3.25 Cr
Start at 32, invest until 60₹1.38 Cr
What seven years of waiting cost₹1.87 CrYou skipped ₹4.2 lakh of contributions. The other ₹1.82 crore is compounding you can never buy back at any price.

₹5,000 a month until age 60 at 12% a year, compounded monthly. 12% is roughly what Indian equity has returned over long periods; it is not promised, and any single decade can be far worse.

Start at 25 in the SIP calculator →

The instinct to wait until you are earning more is exactly backwards. Small amounts started early beat large amounts started late, and it is not close.

The fee you cannot see costs more than every mistake you will make

Two funds hold nearly the same companies. One charges 0.2% a year, the other charges 2.1%. The difference sounds trivial. Over twenty-five years it is this:

What 1.9% a year actually costs

Index fund, 0.2% expense ratio₹1.83 Cr₹10,000 a month for 25 years at 12% before fees.
Active fund, 2.1% expense ratio₹1.32 CrSame money, same market, same 25 years. The manager has to beat the index by 1.9% every year just to draw level.
What the 1.9% difference took₹51.6 LYou paid ₹51.6 lakh for the privilege of a fund manager, and you will never see it on a statement.

Both lines assume 12% before fees, ₹10,000 a month, 25 years. Since April 2026, SEBI caps a fund house's own fee on an equity fund at 2.10% a year, with taxes shown separately; the fee is deducted from the fund's value daily, so it never appears as a charge on your statement.

Run the index fund case in the SIP calculator →

An index fund does not employ anyone to be clever. It buys all fifty Nifty companies in proportion and charges you almost nothing for it. An active fund has to beat that index by 1.9% every single year just to leave you level. Over ten years, most do not.

This is the highest-value paragraph on this page, and it takes about four minutes to act on.

You need three accounts, not one

Demat accountHolds the shares themselves, electronically. Opened with a depository (NSDL or CDSL) through your broker.
Trading accountPlaces the buy and sell orders. This is the app you actually look at.
Bank accountWhere the money comes from and goes back to. All three are linked once, at signup.

All three are opened together, online, in about a day. Most discount brokers charge nothing to open them and nothing to hold shares in delivery.

Documents you will need: PAN, Aadhaar, a cancelled cheque or bank statement, a signature on white paper, and a selfie. Income proof is required only if you plan to trade derivatives.

Trading and investing are different jobs, and only one of them compounds

	Trading	Investing
Holding period	Minutes to weeks	Five years and up
What you are betting on	The next price	The company's earnings in a decade
Time it takes	Most of your day	About an hour a quarter
Tax on gains	20% short-term	12.5% above ₹1.25L a year
Costs	Brokerage on every leg	Almost none
Who reliably wins	A small minority	Anyone who stays invested

SEBI's own study of the derivatives market found the large majority of individual traders lose money, and that the losses concentrate among the most active. Nothing on this page will help you trade. The rest of it will help you invest.

The market falls hard about once a decade. Plan for it now.

The Sensex fell 52% in 2008 and took roughly five years to make it back. It fell around 38% in a matter of weeks in early 2020, and recovered within a year. Both felt identical while they were happening: like the beginning of something worse.

The practical defence is not prediction. It is holding no equity you might need to sell within five years, so that a fall is something you read about rather than something you have to act on.

Nobody knows where the market goes next, including the people on television

This deserves saying plainly, because almost nothing else in this niche says it.

The direction of the market over the next month, quarter or year is not knowable. Anyone stating it confidently is either guessing or selling. What is reasonably well established is far duller: that a diversified basket of listed Indian companies, held for decades, has historically grown faster than inflation and faster than fixed deposits — and that fees, taxes and panic are the three things that reliably eat the difference.

Those three are the ones you control. That is where the effort belongs.

The mistakes that actually cost beginners money

Selling in the fallThe single most expensive habit in retail investing. Everyone who sold in March 2020 locked in the loss; the index recovered inside eleven months.
Buying on a tipBy the time a stock reaches a WhatsApp group, the person who sent it is looking for someone to sell to.
Waiting for the right entryTime in the market beats timing it, and the arithmetic is not close — see the delay figure above.
Confusing a low price with cheapA ₹40 stock is not cheaper than a ₹4,000 stock. Price per share depends on how many shares exist, which tells you nothing.
Checking the portfolio dailyOver a day, equity is a coin flip. Over twenty years, it is not. Daily checking makes you feel the coin flip and act on it.
OvertradingTwenty round trips a month at ₹20 a side is ₹9,600 a year in brokerage alone, before tax — on a portfolio that may not earn that.

How to start, in the order that matters

Clear debt above 12%A credit card at 42% beats any return you will earn. Pay it off first — that is a guaranteed 42% return.
Park six months of expensesIn a savings account or liquid fund. This is what stops you selling shares in a bad month.
Open a Demat and trading accountFree at most discount brokers. KYC is online and takes about a day.
Start a SIP you will not notice₹2,000 a month you never miss beats ₹20,000 you stop after four months.

The whole plan for a first-time investor fits in one line: an index fund SIP you can sustain for ten years without thinking about it, funded by money you will not need before then.

Everything else on this site — ratios, balance sheets, valuation — is for later, and is genuinely worth learning. None of it is a prerequisite for starting.

How a trade actually works

You place an orderBuy 10 shares at market price, or at a limit price you set. The app sends it to the exchange in milliseconds.
The exchange matches itNSE or BSE pairs your buy with somebody else's sell at a price both accept. That match is the price you see quoted.
The clearing corporation guarantees itIt steps between the two sides, so your trade completes even if the other party defaults.
Settlement, one working day laterIndia runs T+1: shares reach your Demat account and money leaves your bank the next working day.

The primary market is where a company sells shares to the public for the first time and receives the money — an IPO. The secondary market is everything afterwards, where shares move between investors and the company is a bystander. Almost everything you will ever do happens in the secondary market.

NSE and BSE are the same shop with two doors

The BSE opened in 1875 and is Asia's oldest exchange; the NSE opened in 1992 and carries the higher trading volume. Both are regulated by SEBI, both settle on a T+1 cycle, and nearly every large company is listed on both.

Both trade 9:15 AM to 3:30 PM on weekdays, with a pre-open session from 9:00. For a beginner buying index funds, the choice between them never arises.

Which companies you are buying

Large cap — the top 100The largest companies by market value. Fall less in a crash, grow slower in a boom. Where a first equity rupee belongs.
Mid cap — 101 to 250More growth, more drawdown. Fell far harder than large caps in 2018 and 2020.
Small cap — 251 onwardsOccasionally spectacular, routinely brutal. Can fall 60% and take years to come back — if the company survives.

A first equity rupee belongs in large caps or in an index fund that holds them. Small caps are where the stories are, and also where the 60% drawdowns are.

The indices you will hear quoted daily

Sensex30 large companies on the BSE, running since 1986. The number the evening news reads out.
Nifty 5050 large companies on the NSE. What most Indian index funds actually track.
Nifty Next 50The 50 companies queued behind the Nifty 50. More volatile; several graduate upward each decade.
Sectoral indicesNifty Bank, Nifty IT and the rest. Useful for seeing which part of the market moved, not as a first investment.

An index is a running average of a fixed basket of companies. When the news says "the market rose 400 points", it means that basket did — which may have almost nothing to do with what you own.

Who else is in the market

Retail investorsYou. Individually small, collectively large — retail now holds a meaningful and growing share of Indian equity.
Domestic institutions (DIIs)Indian mutual funds, insurers and pension funds. Your SIP money reaches the market as DII money.
Foreign investors (FPIs)Overseas funds. Large enough that their buying and selling moves the index, which is why the news reports it daily.
BrokersRoute your order to the exchange. Discount brokers charge a flat fee; full-service brokers charge more and add research.
Exchanges (NSE, BSE)Match buyers to sellers and guarantee the trade settles. You never deal with the person on the other side.
SEBIThe regulator. Sets what brokers may charge, what companies must disclose, and what happens when either cheats.

What can go wrong

The market falls and stays downSensex fell 52% in 2008 and took five years to recover. Not a risk you can diversify away — only one you can outlast.
The company is fine, the sector is notA good business in a broken industry still de-rates. Owning 15 stocks in one sector is owning one stock.
The company was never fineYes Bank went from ₹400 to ₹12. Audited accounts are not a guarantee.
You need the money at the wrong timeThe only risk on this list that is entirely yours to control. Money you need inside five years does not belong in equity.

Questions people actually ask

Figures on this page assume 12% annual returns compounded monthly, which is in line with long-run Indian equity history but is not a forecast and not a promise. Tax rates are those in force from 23 July 2024 and change with each Budget. Check current rates before you file.
