Best Demat for Long-term Investors in India (2026)

A long-term investor trades a handful of times a year — so the broker fee is noise, and the costs that compound are the annual ones: account maintenance charges (AMC) billed every year whether you trade or not, and the per-ISIN debit charges on the rare sell. Over twenty years, the wrong AMC is a ₹6,000–₹7,500 donation; the right structure is close to free. The verified comparison, from the brokers' own schedules and SEBI's BSDA rules, as of November 2026:

AMC: the annual fee you should not pay

Groww: ₹0 AMC. Upstox: ₹0 AMC. HDFC Sky: ₹0 in year one. Zerodha: ₹300 plus GST a year from year two — with the first year free on accounts opened on or after June 1, 2026. Angel One: its current charges page lists AMC at ₹450 a year, or ₹2,950 as a one-time lifetime charge — note our earlier demat-account comparison recorded Angel One at ₹240 plus GST, so the number moved; the issuer's own page is the one to trust on apply day. Sources: groww.in, upstox.com, hdfcsky.com, zerodha.com/charges, angelone.in charges pages, November 2026; the AMC row-by-row table is in our best-demat guide.

The arithmetic is simple enough to do in your head: Zerodha's ₹300 plus GST is ₹354 a year — ₹7,080 over twenty years of holding. The zero-AMC brokers charge that same twenty years: ₹0. There is no platform feature a buy-and-hold investor uses often enough to justify ₹354 a year, which is why the zero-AMC pair is the default answer for this profile.

BSDA: the small-portfolio tier, now generous

SEBI's Basic Services Demat Account caps costs by regulation, not broker marketing: NIL annual maintenance on holdings up to ₹4 lakh, and a maximum of ₹100 a year on holdings up to ₹10 lakh, openable by default at every depository participant since September 2024 (circular 91 of June 2024; a December 24, 2025 enhancement refined the valuation by excluding zero-coupon zero-principal bonds and delisted or suspended securities). Source: SEBI circulars as verified in our beginners and demat-account guides. If your equity holdings sit under ₹4 lakh, the BSDA tier makes AMC a non-decision at every broker — ask for it at account opening, because the default that opens automatically is the one that saves you the fee.

DP charges: the per-sell cost that surprises

Debit charges apply per ISIN — per company — only when shares leave your account on a sell. Zerodha: ₹15.34 per ISIN. Upstox: ₹20 per ISIN. Groww: ₹3.5 plus ₹16.5 (the second waived under ₹100 of debit value) — plus the depository's own ₹3.50 (uniform at CDSL since October 2024) and 18% GST. Source: broker schedules as tabulated in our demat-charges guide. Buy trades never pay it; direct mutual funds are free everywhere. For the long-term investor selling twice a year, the range across brokers is roughly ₹40–₹100 a year — real, but second-order next to AMC.

The worked year, checked

A portfolio of ₹10 lakh across eight stocks, two sells a year of ₹1 lakh each:

• Groww: AMC ₹0; DP ₹20 per company per sell × 2 = ₹40 a year (the ₹3.5 depository component plus GST takes it to ~₹47 — arithmetic per the schedule).
• Upstox: AMC ₹0; DP ₹20 × 2 plus depository and GST ≈ ₹51 a year.
• Zerodha: AMC ₹354 (year two onward); DP ₹15.34 × 2 plus depository and GST ≈ ₹390 a year.
• Any BSDA if holdings stay under ₹4 lakh: AMC ₹0 (or ₹100 up to ₹10 lakh) plus the same small DP line — the cheapest structure in the market by regulation.

Every figure traces to the schedules cited above; the point is not ₹400 versus ₹47 — it is that twenty years of a wrong default compounds into a few weekends of family holiday, for zero benefit.

The direct-MF lane: free by construction

Equity shares need the demat account; direct mutual funds do not — they can be held in statement-of-account form with the fund house or RTA, commission-free, appearing in the same monthly CAS as your shares. If the portfolio is fund-heavy, demat-holding of mutual fund units is optional: it makes loans-against-securities and single-view consolidation tidier, but puts units through DP debit charges on redemption. The zero-conflict default: shares in demat, direct funds in folio form, one CAS reading both — the structure our beginners guide recommends, at a total custody cost of whatever your AMC line says, which the BSDA or a zero-AMC broker sets at or near zero.

The twenty-year table, sized honestly

The zero-AMC column grows only with your selling activity (the per-ISIN DP lines); the AMC column grows on a clock. Neither number is life-changing — but both are pure overhead on a strategy whose returns compound for decades, and the fee never paid is the certain return. Add the intangibles in the same column: a CAS from a single account, nomination updated once, and a login you actually remember at year fifteen.

Corporate actions and the boring maintenance

Long holdings meet the machinery occasionally, and the account should handle it silently: dividends credited to your bank (with TDS above the annual thresholds per our taxation guides), bonus shares auto-credited, rights offers arriving as a choice you must act on, and demergers reshuffling ISINs. Two maintenance duties matter at the twenty-year horizon. Read the CAS monthly — it catches a missed credit in week one instead of year five. And know the IEPF rule: dividends unclaimed for seven consecutive years, and the corresponding shares after that, transfer to the Investor Education and Protection Fund under Section 124 of the Companies Act, 2013 — recoverable, but through a process nobody enjoys. The fix is a bank account that stays current and a calendar reminder to log into the CAS twice a year.

Consolidation: the monthly CAS is your proof

Whatever you choose, the holdings ledger that matters is not the broker's app — it is the Consolidated Account Statement that CDSL and NSDL are required to send monthly when there is activity (and periodically otherwise), covering demat holdings, mutual funds and more in a single statement. Our beginners guide calls it your independent holdings proof, and it is the reason CDSL-versus-NSDL is a non-decision: both depositories feed the same CAS. Read it every month; it is where unrecognised debits, old pledges and missing credits surface first. And when you eventually consolidate accounts, whole-account transfers between identical holders attract no charge, per our transfer guide — switching brokers later is cheap, so an early choice is reversible.

Full-service versus discount: what the premium buys

The full-service houses bundle research, relationship managers and branch service around higher or bundled fee structures; discount brokers strip to the rails. For a buy-and-hold investor executing a written plan, the research is a distraction and the relationship manager is a sales channel — the honest comparison is the fee schedule, the platform's reliability for the two transactions a year that matter, and the custody record. If you want advice, buy it from a fee-only SEBI-registered adviser, not from the account — that separation is the point of the discount structure.

What goes wrong

• Lifetime-AMC prepayments. One broker's ₹2,950 lifetime AMC looks like savings until you want to leave; our charges guide lists closure as free and upfront AMC as refundable pro-rata — but only before you pay it. Zero-AMC beats prepaid-AMC at every holding size the math covers.
• Blanket POAs. The old power-of-attorney gave brokers blanket rights over your account. The modern instrument is the DDPI — limited to debits for trades and pledges — and refusing it entirely just means a one-time OTP per sell. Grant the narrow version or none.
• Multiple demat accounts for offers. The ₹0-opening offers multiply paperwork and split your CAS; consolidation later is cheap but not instant. One account, one CAS, one habit.
• Forgetting the nomination. Nomination is mandatory at opening (or a signed opt-out) — for a twenty-year account it is the single most consequential field in the form, as our beginners guide stresses.

The verdict

The long-term-investor shortlist is short: a zero-AMC discount account (Groww or Upstox on the verified schedules), the BSDA tier if holdings are small, DDPI instead of a blanket POA, and the monthly CAS read as a ritual. Zerodha remains perfectly reasonable if its platform is your home — ₹354 a year is a preference fee, not a trap — but the zero-AMC pair wins the arithmetic on every line. Set it up once, automate the investing through UPI-blocked funds, and let the compounding happen in the assets, not the fees. The switching mechanics, if you are migrating an old account, are in our transfer guide; the account-opening flow, in our how-to-open guide.
