How Indian Traders Calculate Profit After Brokerage and Taxes

Many Indian traders look at the profit shown on a trading platform and assume that number is the money they actually earned. That is not always the amount that finally remains after brokerage, GST, STT, exchange transaction charges, SEBI turnover fees, stamp duty and other applicable costs.

For futures traders especially, the calculation matters because STT on the sale of futures increased to 0.05% from April 1, 2026. NSE states that futures STT is calculated on the actual traded price and is payable by the seller. Brokerage services are also subject to 18% GST, while other transaction charges can vary by exchange and broker. NSE: STT, SEBI fees, stamp duty and GST and NSE: Securities Transaction Tax computation.

This guide explains a practical way to calculate net trading profit after brokerage and taxes for Indian traders, with examples for futures and a separate explanation of how income tax fits into the calculation.

Gross Profit vs Net Trading Profit

The first distinction is simple:

• Gross trading profit: Profit or loss generated by the price movement of your trades before transaction costs.
• Trading costs: Brokerage, GST on applicable broker services, STT, exchange transaction charges, SEBI turnover fees, stamp duty and other applicable charges.
• Net trading profit: Gross trading profit minus the transaction costs charged to the account.
• Income-tax liability: A separate tax calculation based on your taxable income and applicable tax regime. It should not simply be deducted from every individual trade’s platform P&L.

That last point is important. A broker’s contract note can show transaction charges, but your final income-tax liability is determined when your taxable income for the relevant tax year is calculated. Therefore, net-of-charges trading P&L and final after-income-tax cash profit are two different calculations.

The Basic Formula Indian Traders Can Use

A practical formula is:

Net Trading Profit = Gross Trading Profit − Brokerage − GST on Brokerage/Applicable Broker Services − STT − Exchange Charges − SEBI Turnover Fees − Stamp Duty − Other Applicable Charges

Then, separately:

Post-Income-Tax Profit = Taxable Trading Profit − Income-Tax Liability Attributable to That Income

Do not use the second formula as a substitute for professional tax computation. Your actual income-tax liability can depend on your total income, eligible expenses, losses, deductions, tax regime and other facts.

What Charges Reduce a Trader’s Profit?

1. Brokerage

Brokerage depends on your broker, product, plan and order structure. Some brokers charge a fixed amount per executed order, while others use different pricing models.

For a clean calculation, take the exact brokerage shown on your contract note rather than assuming that every broker charges the same amount.

2. GST on Brokerage and Applicable Services

NSE currently lists GST on stock-broker services at 18%. This is not the same as saying that 18% of your trading turnover is GST. GST is generally applied to the taxable value of applicable broker services and charges, subject to the broker’s billing structure and applicable GST rules. NSE levy information.

3. STT on Futures

For securities futures, NSE states that from April 1, 2026, STT on the sale of futures is 0.05%. The taxable value for futures is the actual traded price. STT is payable by the seller. NSE STT computation.

This is a major point for anyone comparing older articles or calculators. The futures STT rate was 0.02% through March 31, 2026 and increased to 0.05% from April 1, 2026. The Income Tax Department’s 2026 Budget FAQ confirms the change and effective date. Income Tax Department: Budget 2026 STT FAQ.

4. Exchange Transaction Charges

Exchanges can levy transaction charges on trades. The exact amount depends on the exchange, segment and applicable circulars. These should be taken from the contract note or broker’s current tariff rather than estimated from an old article.

5. SEBI Turnover Fees

NSE currently lists a SEBI turnover fee of 0.0001%, or ₹10 per crore, for applicable securities transactions other than debt securities. The exact applicability should be checked against the instrument and transaction type. NSE: SEBI turnover fees.

6. Stamp Duty

NSE lists stamp duty for equity futures at 0.002% on the buyer. Commodity futures are also listed at 0.002% on the buyer, while other derivatives have different rates. Your contract note should be treated as the practical record of the amount charged for your trade. NSE: Stamp duty.

Example: ₹10,000 Gross Profit From Futures

Suppose an Indian trader closes a futures position with a gross trading profit of ₹10,000.

For illustration, assume the contract note shows:

The ₹9,717 figure is only a hypothetical example. The actual amount will depend on the traded value, number of orders, broker pricing, exchange, instrument, applicable rates and your contract note.

How the ₹125 Futures STT Is Calculated

If the taxable sale value of the futures transaction is ₹2,50,000, and the applicable STT rate is 0.05%:

STT = ₹2,50,000 × 0.05% = ₹125

Notice that STT is not calculated as 0.05% of your ₹10,000 profit. It is calculated on the applicable traded value of the futures sale. This is why a trader can have a relatively small profit but still incur meaningful transaction costs when turnover is high.

Why Turnover Matters So Much

Consider two traders who each make ₹10,000 gross profit.

Trader A makes the profit with relatively low turnover. Trader B makes the same profit by entering and exiting many times and generating much higher traded value.

Their gross P&L is identical, but their transaction costs can be very different. Brokerage may rise with the number of orders, while STT and some other charges are linked to transaction values or the relevant side of the trade.

This is one reason gross P&L alone is a poor way to judge trading efficiency. For a broader risk perspective, see our guide on what drawdown means in trading and prop firm accounts.

Round-Trip Trading: Don’t Forget Both Sides

A common calculation mistake is to look only at the entry or only at the exit.

A typical futures trade has:

1. Entry transaction
2. Position held while the market moves
3. Exit transaction

Some charges apply differently to buying and selling. For example, NSE’s current futures STT is specifically a tax on the sale of futures. Stamp duty is listed on the buyer for equity futures. Brokerage and GST treatment depends on the broker’s service charges.

Therefore, the safest method is to calculate costs from the complete contract note rather than applying one generic percentage to the entire P&L.

Example With a Larger Futures Turnover

Suppose a trader generates ₹50,000 gross profit over several futures trades. Assume the relevant taxable sale value for STT across those trades is ₹20,00,000.

At 0.05%:

STT = ₹20,00,000 × 0.05% = ₹1,000

If the trader also pays ₹500 brokerage and ₹90 GST on brokerage, plus ₹250 in other applicable charges, the simplified calculation would be:

Again, this is an educational example, not a universal cost schedule.

Does Income Tax Get Deducted From Every Trade?

Usually, you should think about income tax at the tax-year level, not as a simple percentage removed from each winning trade.

For Indian traders who have business/profession income, the Income Tax Department provides ITR-3 for individuals and HUFs with income under the head of profits and gains of business or profession. The current ITR materials also contain specific fields for turnover from Futures & Options Trading and income from Futures & Options Trading. Income Tax Department: ITR downloads and 2026 notified ITR form.

That means a trader should maintain records of trading results and eligible expenses throughout the year instead of assuming that the broker’s displayed net P&L is automatically the final taxable amount.

Trading Costs vs Income Tax: Keep Them Separate

There are two different layers:

Layer 1: Trade-level economics

This answers: How much did the trade actually make after transaction charges?

Example:

₹10,000 gross profit − ₹283 transaction costs = ₹9,717 net trading profit.

Layer 2: Tax-year computation

This answers: How much taxable income do I have and what income-tax liability applies?

This can involve your overall business/profession income, eligible expenses, brought-forward losses where applicable, other income, deductions and the applicable tax rules. A CA should be consulted for a trader-specific tax position.

What About Trading Losses?

A losing trade still creates transaction costs. If a trade loses ₹5,000 before costs and incurs ₹200 of charges, the economic loss is ₹5,200.

This is why traders should not calculate their expectancy using only entry and exit price differences. A strategy that appears marginally profitable before costs can become unprofitable after brokerage, STT and other charges.

How Indian Traders Should Calculate Monthly Net Profit

A practical monthly worksheet can contain these columns:

This makes it much easier to compare strategies, brokers and trading frequency.

Gross Profit Percentage Can Be Misleading

Suppose a trader says, “I made 2% this month.” The important follow-up question is: 2% before or after transaction costs?

If the trader generates a high turnover to produce that return, charges can materially reduce the actual result. The same issue appears when comparing intraday, futures and other active strategies.

For performance tracking, consider recording at least:

• Gross P&L
• Net P&L after charges
• Total turnover
• Total number of trades
• Average profit per trade
• Average loss per trade
• Transaction costs as a percentage of gross profit
• Maximum drawdown

How to Calculate Net Profit From Your Contract Note

1. Download the complete contract note or ledger for the trading day.
2. Record the gross realized P&L.
3. Add up brokerage for the relevant trades.
4. Add GST charged on applicable broker/service components.
5. Record STT exactly as shown.
6. Record exchange transaction charges.
7. Record SEBI turnover fees.
8. Record stamp duty and any other applicable charges.
9. Subtract the total transaction costs from gross P&L.
10. Maintain the records for your tax-year calculation.

This method is more reliable than using an online calculator with a generic brokerage number because broker tariffs and exchange charges can change. If you also trade futures through prop firms, our guide to how futures prop firm Maximum Loss Limit is calculated explains a separate layer of account-level risk.

Common Mistakes Indian Traders Make

• Using the old 0.02% futures STT rate: From April 1, 2026, the rate for sale of futures in securities is 0.05%.
• Calculating STT on profit: Futures STT is based on the applicable traded value of the futures sale, not your profit amount.
• Ignoring GST: Brokerage and applicable broker services can attract 18% GST.
• Ignoring turnover: High turnover can produce much higher costs even when gross profit is unchanged.
• Mixing transaction costs with income tax: Trade-level charges and annual income-tax liability are different calculations.
• Using an outdated brokerage schedule: Always check your broker’s current pricing and contract note.
• Not keeping records: Save contract notes, ledgers, P&L reports and relevant tax documents.

Futures vs Options: Don’t Use the Same Tax Calculator

Futures and options have different STT rules. For example, NSE currently lists sale of futures at 0.05%, while sale of an option is subject to a different rate and taxable base. Therefore, a calculator designed for futures should not automatically be used for option trades.

For options, the taxable value can depend on the option premium or, where an option is exercised, the applicable intrinsic value rules. NSE STT rules.

Why This Matters for Active Traders

Active trading is not just about finding winning entries. A strategy needs enough edge to overcome its execution and transaction costs.

For example, if a strategy produces ₹15,000 gross monthly profit but costs ₹5,000 in brokerage and taxes/charges, the trader’s net trading result is ₹10,000 before considering the separate income-tax calculation. If another strategy produces the same gross profit with much lower turnover and costs, the economic result can be very different.

This is why serious performance analysis should focus on net expectancy, not just gross winning trades. For traders comparing futures activity from India, our guide to NQ futures prop trading risk per trade also covers contract value and risk sizing.

Quick Formula for Indian Traders

Use this simplified workflow:

Gross P&L
− Brokerage
− GST on applicable broker/service charges
− STT
− Exchange transaction charges
− SEBI turnover fees
− Stamp duty
− Other applicable charges
= Net Trading P&L

Then calculate your annual taxable income separately under the applicable income-tax rules.

• Include applicable stamp duty.
• Calculate net P&L instead of relying only on gross P&L.
• Keep futures and options calculations separate.
• Track turnover and expenses throughout the tax year.
• Use your contract notes and ledger as the primary transaction records.
• For your final income-tax filing, confirm the treatment with a qualified tax professional.
