To calculate profit and loss in the stock market, subtract the total purchase cost of your shares from the sale proceeds. Then deduct brokerage, Securities Transaction Tax (STT), GST, stamp duty, and other applicable charges to estimate your net trading profit or loss.

Stock profit and loss formula:

Gross P&L = Selling Value − Purchase Value

Net P&L = Gross P&L − Trading Charges

For example, if you buy 100 shares at ₹250 each and sell them at ₹275 each:

• Purchase value: ₹25,000
• Selling value: ₹27,500
• Gross profit: ₹2,500
• Gross return: 10%

Your actual profit will be lower after applicable trading charges and taxes.

What Is Profit and Loss in the Stock Market?

• Profit: You sell shares for more than their purchase cost.
• Loss: You sell shares for less than their purchase cost.
• Realised P&L: Profit or loss from shares you have sold.
• Unrealised P&L: The current estimated gain or loss on shares you still hold.

Stock Market Profit and Loss Formula

1. Gross Profit or Loss

Gross P&L = (Selling Price − Buying Price) × Quantity

If you buy 50 shares at ₹200 and sell them at ₹230:

(₹230 − ₹200) × 50 = ₹1,500 gross profit.

If you sell at ₹180 instead:

(₹180 − ₹200) × 50 = −₹1,000 gross loss.

2. Profit Percentage on Shares

Profit Percentage = (Profit ÷ Purchase Cost) × 100

If purchase cost is ₹20,000 and gross profit is ₹2,000, the gross return is 10%.

Net Return % = (Net Profit ÷ Total Investment Cost) × 100

How to Calculate Stock Market Profit and Loss in Rupees: Example

Step 1: Calculate Purchase Value

100 × ₹250 = ₹25,000

Step 2: Calculate Selling Value

100 × ₹275 = ₹27,500

Step 3: Calculate Gross Profit

₹27,500 − ₹25,000 = ₹2,500

Step 4: Calculate Gross Profit Percentage

₹2,500 ÷ ₹25,000 × 100 = 10%

Note: This is gross profit. Brokerage, STT, GST, stamp duty, exchange charges, and other applicable costs must be considered to estimate net trading profit.

How to Calculate Average Buying Price of Shares

When you buy the same stock multiple times at different prices, use a weighted average.

Average Buying Price = Total Purchase Value ÷ Total Shares Purchased

₹3,400 ÷ 30 = ₹113.33 per share, before charges included in the cost basis.

Do not simply average ₹100 and ₹120, because the quantities purchased were different.

Absolute Return vs CAGR vs XIRR

Absolute Return

Absolute Return = [(Ending Value − Beginning Value) ÷ Beginning Value] × 100

If ₹50,000 becomes ₹60,000, the absolute return is 20%. This does not account for the investment period.

CAGR: Compound Annual Growth Rate

CAGR = (Ending Value ÷ Beginning Value)^(1/n) − 1

Here, n is the investment period in years.

If ₹50,000 becomes ₹60,000 in two years:

(60,000 ÷ 50,000)^(1/2) − 1 ≈ 9.54% per year.

CAGR is useful when there is one initial investment and one final value. It does not show volatility or the path of returns.

XIRR for Multiple Investments

XIRR calculates an annualized return using the timing and size of cash flows.

=XIRR(values, dates)

Use negative values for investments and positive values for cash received or final portfolio value. XIRR is useful for staggered investments and withdrawals.

Realised vs Unrealised Profit and Loss

Unrealised P&L can change with the market price and is not guaranteed profit.

Trading Charges That Affect Your Net Profit in India

Common charges include brokerage, STT, GST, stamp duty, exchange transaction charges, SEBI turnover fees, DP charges, and other broker-specific fees.

Check NSE charges and levies for current statutory rates.

GST is not charged on the share purchase value itself. It applies to taxable brokerage and related services/charges. The GST rate on brokerage services is 18%. See the CBIC GST FAQ.

How to Calculate Net Profit After Brokerage and STT

Suppose gross profit is ₹2,500 and total charges shown in your contract note are ₹80.

Net Trading Profit = ₹2,500 − ₹80 = ₹2,420

The ₹80 is illustrative, not a universal estimate. Actual charges depend on broker, exchange, order size, and transaction type.

Intraday Profit and Loss Calculation

For a long intraday trade:

Gross Profit = (Sell Price − Buy Price) × Quantity

Example: Buy 200 shares at ₹150 and sell at ₹154.

(₹154 − ₹150) × 200 = ₹800 gross profit.

Subtract applicable brokerage, STT, GST, exchange charges, stamp duty, and other fees to estimate net profit.

Delivery vs Intraday Profit Calculation

F&O Profit and Loss Calculation

Futures P&L

Futures P&L = (Exit Price − Entry Price) × Quantity

For a short position, the direction is reversed. P&L depends on contract quantity and price movement, not just margin deposited.

Options P&L

For a bought option:

Gross P&L = (Exit Premium − Entry Premium) × Quantity

Example: Buy an option at ₹100 premium and sell it at ₹130, with quantity 50.

(₹130 − ₹100) × 50 = ₹1,500 gross profit.

This simple formula applies to a closed long-option position. Multi-leg strategies, expiry settlement, exercise, and short options require more detailed calculations.

From 1 April 2026, STT on futures sold is 0.05%, STT on options sold is 0.15% of premium, and exercised options are subject to 0.15% STT on intrinsic value. See NSE’s STT update.

Capital Gains Tax on Shares in India

Trading profit and taxable income are not necessarily the same. Tax depends on whether shares are held as investments or traded as business activity, holding period, transaction type, and applicable law.

The Income-tax Act, 2025 came into effect on 1 April 2026. The following is a general guide for qualifying listed equity shares.

Short-Term Capital Gains (STCG)

• Shares held for 12 months or less are generally short-term.
• Qualifying listed equity STCG is generally taxed at 20% for transfers on or after 23 July 2024, subject to applicable STT conditions.

Long-Term Capital Gains (LTCG)

• Shares held for more than 12 months are generally long-term.
• Qualifying listed equity LTCG is generally taxed at 12.5% on eligible aggregate gains exceeding ₹1.25 lakh in the relevant tax year.

Surcharge and cess may apply. Conditions and exceptions matter. See the Income Tax Department share taxation guide and the Income-tax Act, 2025.

Intraday Trading Tax

Intraday equity trading is generally treated as speculative business income rather than capital gains.

F&O Tax

F&O trading is generally treated as non-speculative business income, subject to the facts and applicable law. Business income is taxed under the applicable income-tax rules rather than automatically at special capital gains rates.

Frequent trading, leverage, and substantial intraday or F&O activity may require professional tax advice. Classification depends on facts.

How to Set Off Stock Market Losses

Capital Gains Losses

• Short-term capital loss can generally be adjusted against short-term or long-term capital gains.
• Long-term capital loss can generally be adjusted only against long-term capital gains.
• Eligible capital losses can generally be carried forward for up to eight tax years, subject to conditions.

Filing the return within the applicable due date is important to preserve the right to carry forward losses.

Intraday Trading Losses

Speculative business losses generally can be set off only against speculative business profits and may be carried forward for up to four tax years, subject to filing conditions.

F&O Losses

F&O losses are generally non-speculative business losses and follow business-loss rules. Their treatment differs from capital losses and intraday speculative losses.

See the Income Tax Department loss set-off guidance.

Why Broker P&L and Tax P&L May Differ

A broker’s P&L may not include every item relevant to your tax return, including corporate actions, shares transferred between brokers, other broker accounts, tax classification, loss carry-forward, and tax adjustments.

Use broker reports as records and reconcile them with tradebook data, contract notes, and tax requirements.

Use a Stock Profit and Loss Calculator on ToolsNCalc

A stock profit calculator can help estimate purchase value, selling value, gross P&L, profit percentage, average buying price, trading charges, and net trading P&L.

For an Indian stock calculator, users should be able to enter quantity, buying price, selling price, and transaction type.

If the calculator excludes broker-specific fees, STT, stamp duty, GST, and DP charges, it should clearly label its output as gross profit or an estimate.

Frequently Asked Questions

How do I calculate profit and loss in the stock market?

Subtract purchase value from selling value. Then deduct brokerage and applicable trading charges to estimate net trading P&L.

How do I calculate profit percentage on shares?

Divide profit by purchase cost and multiply by 100. For net return, include applicable charges.

How do I calculate net profit after brokerage and STT?

Calculate gross profit first, then subtract brokerage, STT, GST, stamp duty, exchange charges, SEBI fees, and applicable DP charges.

What is the difference between realised and unrealised profit?

Realised profit comes from selling shares. Unrealised profit is the current estimated gain on shares still held.

Is stock market profit taxable in India?

Yes, profits may be taxable. Tax treatment depends on investment or trading classification, holding period, transaction type, and applicable rules.

Is CAGR the same as absolute return?

No. Absolute return measures total percentage gain or loss. CAGR estimates annualized growth. XIRR is useful when cash flows occur on different dates.

Conclusion

Calculating stock market profit and loss is straightforward once you separate gross returns, trading charges, and tax.

Start with purchase and sale values. Calculate gross P&L and percentage return. Then subtract brokerage, STT, GST, stamp duty, exchange fees, and other applicable charges to estimate net trading profit.

Use CAGR for a single initial investment and final value, and XIRR when cash flows occur on different dates.

For Indian traders, reviewing the broker contract note and understanding tax classification are essential. A positive trading P&L does not automatically mean the same amount is your final after-tax profit.
