Let us derive the total cost of a trade, not memorise it. We build it piece by piece.
Suppose you trade a turnoverT=Price×Quantity on one leg (buy or sell).
Step 1 — Brokerage. The broker charges either flat or percentage.
B=min(f,b⋅T)Why this step? Discount brokers cap brokerage at a flat f (e.g. ₹20) OR a percentage b (e.g. 0.03%), whichever is lower — so we take the min.
Step 2 — STT (Securities Transaction Tax). A statutory tax on turnover.
STT=s⋅TWhy this step? For delivery equitys=0.1% on both buy and sell. For intraday, s=0.025% on the sell side only.
Step 3 — Exchange Transaction Charge.E=e⋅TWhy this step? NSE/BSE charge a tiny % (≈ 0.00297% for NSE equity) for using their matching engine.
Step 4 — SEBI turnover fee.SEBI=k⋅T,k=0.0001%=₹1 crore10Why this step? SEBI charges ₹10 per crore of turnover to fund the regulator.
Step 5 — Stamp Duty (buy side only).D=d⋅TWhy this step? A state tax on creation of the security holding, so it applies to purchase only (d=0.015% for delivery equity).
Step 6 — GST. GST at g=18% is applied only on (brokerage + exchange charge + SEBI fee).
GST=g(B+E+SEBI)Why this step? GST is a tax on the service portion — it does not apply to STT or stamp duty (those are already taxes; you don't tax a tax here).
Step 7 — DP charge (sell side only).DP=c(a flat amount, e.g. ₹13.5 + GST, per scrip per day)Why this step? It is a flat record-keeping fee, independent of turnover — so it does NOT scale with T.
DP charge is levied on which leg of a delivery trade?
Only the SELL side (debit of shares), flat per scrip per day.
Is the DP charge a percentage or a flat fee?
A flat fee (e.g. ~₹13.5 + GST), independent of turnover.
What does AMC stand for and how often is it charged?
Annual Maintenance Charge — a recurring yearly (sometimes monthly/quarterly) fee to keep the demat account active.
Name the statutory fees on an equity trade.
STT, Exchange transaction charge, SEBI turnover fee, Stamp duty, and GST.
STT rate & sides for delivery equity?
0.1% on BOTH buy and sell.
STT for intraday equity?
0.025% on the SELL side only.
Which leg is stamp duty charged on?
Buy side only (0.015% for delivery equity).
GST rate and on what base?
18% on (brokerage + exchange transaction charge + SEBI fee) — NOT on STT or stamp duty.
SEBI turnover fee amount?
₹10 per ₹1 crore of turnover (0.0001%).
Why does DP charge hurt small trades most?
It's flat, so as a % of a tiny turnover it becomes large (e.g. ₹15.93 on ₹500 = 3.19%).
What is a BSDA and its benefit?
Basic Services Demat Account — zero/low AMC for holdings up to ₹4 lakh, ideal for small investors.
Where do you find the exact fee breakdown of a trade?
The contract note issued by the broker.
Recall Feynman: explain to a 12-year-old
Imagine your shares live in a special locker (the depository). Your broker is like the locker-keeper. Every time you take shares out to sell, the locker-keeper charges a small fixed coin (DP charge) — same coin whether you take out one share or a thousand, so taking out just one share is a bad deal. The locker also has a yearly rent (AMC) you pay even if you never open it. And the king (government) takes a little tax every time you trade (STT, stamp, GST) — you can't argue with the king. So the price on the screen is never the real price; add the locker coin, the rent, and the king's tax.
Dekho, jab tum share kharidte ya bechte ho, toh sirf share ka price hi cost nahi hota. Uske upar teen tarah ke chhote-chhote charges lagte hain. Pehla hai DP charge — yeh tab lagta hai jab tum share bechte ho (sell side), aur yeh flat fee hota hai (jaise ₹13.5 + GST) per scrip per day, chahe tum 1 share becho ya 1000. Isi wajah se chhote trades pe yeh bahut bura lagta hai — ₹500 ke sell pe ₹15.93 matlab 3% se zyada gaya!
Doosra hai AMC (Annual Maintenance Charge) — yeh demat account ko chalu rakhne ka saalana kiraya hai. Chahe tum trade karo ya na karo, yeh har saal katta hai. Agar tumhare account mein sirf ₹5,000 ke share hain aur AMC ₹300 hai, toh matlab 6% drag — isliye chhote investors ko BSDA account lena chahiye jismein ₹4 lakh tak AMC lagbhag zero hota hai.
Teesra hai statutory fees — yeh sarkar aur regulator ke charges hain jinko tum avoid nahi kar sakte. Insme aata hai STT (delivery mein 0.1% dono taraf, intraday mein 0.025% sirf sell pe), stamp duty (sirf buy side), exchange charge, SEBI fee, aur GST 18%. Yaad rakho — GST sirf brokerage + exchange charge + SEBI fee pe lagta hai, STT ya stamp duty pe nahi.
