A demat account — short for dematerialised account — holds your shares and
securities in electronic form. Think of it as a locker for your investments: where a savings account
holds your money, a demat account holds your stocks, ETFs, bonds, sovereign gold bonds, and mutual
fund units. Before 1996, investors held paper share certificates that could be lost, torn, forged or
stuck in transfer for months. Dematerialisation ended all that. Today every share you buy on the NSE
or BSE lands in your demat account electronically, usually by the next working day.
How money, trading and demat fit together
Three accounts work as a chain, and confusing them is the most common beginner mistake I see. Your
bank account holds cash. Your trading account is the engine that
places buy and sell orders on the exchange. Your demat account stores whatever you
buy. When you buy, money leaves your bank, the trade executes through your trading account, and the
shares are credited to your demat account. When you sell, the shares leave your demat account and
the proceeds return to your bank.

Most brokers now bundle these. A 2-in-1 account (Zerodha, Groww, Upstox, Dhan and
most discount brokers) combines trading and demat, and you link your existing bank. A 3-in-1
account (ICICI Direct, HDFC Securities, Kotak, Axis Direct, SBI Securities) adds the
bank account itself, so funds move instantly between all three — convenient, but usually at higher
brokerage.
Field note 2-in-1 vs 3-in-1, from experience. I keep a 3-in-1 account with a bank broker purely for the "money moves in one tap" convenience during volatile mornings — but I place most delivery trades through a discount broker, because over a year the brokerage gap on the bank account cost more than the convenience was worth. If you're disciplined about adding funds via UPI the night before, you rarely need 3-in-1.
CDSL vs NSDL — the two depositories
Your shares aren't actually held by your broker. They sit with one of India's two
depositories: CDSL (Central Depository Services Limited) or NSDL (National
Securities Depository Limited). Your broker is only the Depository Participant (DP)
— the agent that connects you to the depository. As of 2026, India has crossed 22 crore
demat accounts between the two, with CDSL holding the larger share of retail accounts
(around 18 crore) and NSDL the larger share of institutional assets.
For a normal investor, which depository your broker uses barely matters — your shares are equally
safe under SEBI regulation either way. It only shows up in small details: your demat account number
format (a 16-digit number on CDSL, an "IN"-prefixed number on NSDL) and occasionally the exact DP
charge. Discount brokers like Zerodha, Groww, Upstox, Angel One and Dhan are mostly on CDSL; a few
full-service and bank brokers use NSDL.
Types of demat account
One size doesn't fit everyone. The account type changes your AMC and, sometimes, your eligibility.

| BSDA (Basic Services) |
Small investors |
₹0 AMC up to ₹4 lakh holding; reduced AMC up to ₹10 lakh |
| NRI — Repatriable |
NRIs investing foreign funds |
Linked to an NRE bank account; funds can go back abroad |
| NRI — Non-repatriable |
NRIs investing India income |
Linked to an NRO account; funds stay in India |
| Minor |
Children under 18 |
Operated by a guardian; can't trade F&O or intraday |
| Joint |
Two or three holders |
All holders sign; useful for family holdings |
The BSDA is the underused one. If your total holdings stay under ₹4 lakh, most
brokers must offer you zero AMC under this category — you often just have to opt in. Several of the
"₹300 AMC" brokers in our table effectively become ₹0 AMC for a small investor who requests BSDA.
Always ask.
