Enter your buy and sell price and quantity. This STT and transaction charges calculator shows only the government and exchange levies, the same for every broker, across delivery, intraday, futures and options.
STT and Transaction Charges Calculator
Statutory charges only: no brokerage, since that varies by broker and this does not.
These charges apply at every broker. Only brokerage itself differs, and that is left out here on purpose.

Illustrative estimates. STT rates reflect the Budget 2026 revision effective 1 April 2026. Verify current rates with your exchange or broker.
Switch brokers and your brokerage changes. STT does not. It is set by the government, the same for every trader on every platform, and it is often the single biggest line item on a contract note. An STT and transaction charges calculator shows just that part, with brokerage deliberately left out.
How do you use this STT and transaction charges calculator in 3 steps?
- Choose the segment: equity delivery, equity intraday, futures or options.
- Enter your buy price, sell price and quantity. For futures and options, quantity is lot size times the number of lots.
- Read the STT, the total statutory charges, and how your segment compares with the other three on the same trade.
The Stock Charcha STT and transaction charges calculator isolates exactly what the government and exchanges take, separate from what any one broker charges, which our brokerage calculator covers in full.
What counts as a statutory charge, and what does not?
Five charges apply here, and every one of them is fixed by regulation, not by your broker.
Total statutory charges = STT + Exchange transaction charges + Stamp duty + SEBI turnover charges + GST on the above
Brokerage is excluded on purpose, since it is the one cost that genuinely differs from platform to platform. These five apply identically whether you trade through a full-service broker or a discount one.
What are the current STT rates by segment?
STT changed for futures and options under the Budget 2026 revision, effective 1 April 2026. Delivery and intraday rates were not revised in that Budget.
| Segment | STT rate | Charged on |
|---|---|---|
| Equity Delivery | 0.1% | Both buy and sell value |
| Equity Intraday | 0.025% | Sell value only |
| Futures | 0.05% | Sell value only |
| Options | 0.15% | Premium, sell side only |
Futures STT rose from 0.02% to 0.05%, and options STT from 0.10% to 0.15%, both roughly 50% to 150% increases. Verify the current figure on the NSE website before relying on it for a large trade.
What does a worked example look like?
Take 100 shares bought and sold at ₹1,000 on delivery. These figures are illustrative.
| Charge | Amount |
|---|---|
| STT | ₹200.00 |
| Exchange transaction charges | ₹6.14 |
| Stamp duty | ₹15.00 |
| SEBI turnover charges | ₹0.20 |
| GST | ₹1.14 |
| Total statutory charges | ₹222.48 |
STT alone is about 90% of the total here. It dominates every segment except options, where the premium base is much smaller than the underlying value. This is the pattern the STT and transaction charges calculator shows on every segment you try.
How do the four segments compare on a similar-sized trade?
Here is STT and the total statutory charges on a roughly similar trade size in each segment.
| Segment | STT | Total statutory charges |
|---|---|---|
| Equity Delivery | ₹200.00 | ₹222.48 |
| Equity Intraday | ₹25.00 | ₹35.48 |
| Futures | ₹815.75 | ₹918.57 |
| Options | ₹20.25 | ₹30.85 |
Delivery carries the heaviest STT, because it applies on both the buy and sell side, not just one. Options carries the highest rate, 0.15%, but on the much smaller premium rather than the underlying contract value.
Why does STT alone matter for frequent traders?
A single trade’s STT looks small, but it is charged on every sell, every day, with no discount for volume. A trader doing ten intraday round trips a day pays STT ten times over, while a long-term investor pays it once per holding.
This is also why STT sits outside most broker discounting. A zero-brokerage plan still leaves STT, exchange charges and stamp duty untouched, so the STT and transaction charges calculator shows the floor that no broker promotion can remove. Stock Charcha built this page specifically to separate that floor from brokerage itself.
What does this STT and transaction charges calculator leave out?
It does not include brokerage, DP charges, or income tax on any profit. Our stock profit and loss calculator and share capital gains tax calculator cover those. Exchange transaction charges can differ slightly between NSE and BSE, and this calculator uses NSE rates.

Where should you go after using the STT and transaction charges calculator?
For the full charge picture including brokerage, use the brokerage calculator, and for the exact price you need to clear, the break-even calculator. For tax on your gains, see the share capital gains tax calculator.
The Trading section of the Charcha Knowledge Hub has more. Run the Stock Charcha STT and transaction charges calculator before a high-frequency strategy, so the fixed floor is a known cost, not a surprise.

Frequently asked questions
Does STT apply even if I lose money on a trade?
Yes. STT is charged on the transaction value, not on profit, so it applies whether the trade makes money or loses it. A losing trade still pays STT, exchange charges and stamp duty on the turnover involved.
Why did STT on futures and options increase in 2026?
Budget 2026 raised STT on futures from 0.02% to 0.05% and on options premium from 0.10% to 0.15%, effective 1 April 2026, as part of measures aimed at the fast-growing derivatives segment. Check the NSE website for the exact current rate.
Is STT the same at every broker?
Yes. STT, exchange transaction charges, stamp duty and SEBI charges are set by the government and exchanges, not by your broker, so they are identical across brokers for the same trade. Only brokerage itself can differ.
Why is options STT charged only on the premium, not the full contract value?
Because the premium, not the strike or the underlying price, is what actually changes hands when an option is bought or sold. Taxing the full notional value would make STT far larger than the trade itself in most cases.
Does this STT and transaction charges calculator include GST?
Yes, but only GST on the exchange transaction charges and SEBI turnover charges, which is how GST actually applies here. STT and stamp duty are taxes in their own right and do not themselves attract GST.
