Stock Profit & Loss Calculator: Net P&L, Returns, and Breakeven Price.
Use this fast and accurate Stock Profit & Loss Calculator to compute net P&L, percentage return, breakeven price, and average cost basis in seconds using standard portfolio math adapted for real trading fees.
Enter buy and sell details, number of shares, and optional fee components to transform gross gains into actual net outcomes that reflect brokerage, taxes, and regulatory charges where applicable.
Designed for clarity, speed, and stability on mobile and desktop, the page aligns with Google’s page experience guidance and Core Web Vitals so interactions feel instant and predictable.
What the calculator does
Computes gross and net P&L with percentage returns, including optional brokerage, exchange/regulatory fees, and taxes.
Finds breakeven sell price and target sell price for a desired profit after costs, reflecting realistic trading scenarios.
Supports average price after multiple buys and FIFO cost-basis context for portfolio tracking where relevant.
Provides examples and notes for common markets (India fees like STT/GST/SEBI/stamp duty; U.S. regulatory fees like FINRA TAF and SEC Section 31) to improve accuracy.
These features match high-intent searches like “stock profit calculator,” “share profit calculator,” “intraday profit calculator,” “brokerage calculator,” “break-even stock price,” and “percentage return calculator.”
How profit and loss are calculated
At its core, the nominal profit or loss per share is sell price minus buy price, multiplied by the number of shares for the total gross amount.
Percentage return uses the cost basis in the denominator: Return%=Sell−BuyBuy×100, with quantity included to convert to total dollar change, enabling like-for-like performance comparisons.
Real-world P&L includes costs and benefits: Net P&L=(Sell−Buy)×Quantity+Dividends−Trading Fees−Taxes, which this tool supports through optional fee and dividend inputs.
This approach aligns with portfolio fundamentals and helps avoid overstating gains by ignoring transaction costs.
Key formulas used
Gross P&L: Gross P&L=(Sell−Buy)×Qty.
Net P&L: Net P&L=Gross P&L+Dividends−∑Fees.
Percentage return: Return%=Sell−BuyBuy×100.
Breakeven sell price (no dividends): SellBE=Buy+∑FeesQty, extended to include separate buy/sell-side fees.
Average price after multiple buys: Avg Buy=∑(Pricei×Qtyi)∑Qtyi for weighted cost basis.
FIFO note: Portfolio providers often compute realized P&L using FIFO, so the first acquired shares are considered sold first.
Each equation reflects mainstream practices for P&L and return calculation and is adaptable with explicit fee inputs for regional accuracy.
Fees and charges supported
Brokerage, exchange charges, taxes, and regulatory fees can materially shift net results, so the calculator allows itemized inputs to model actual costs.
Common components include broker commissions, exchange/transaction charges, government taxes, and market-specific regulatory fees on sales.
India examples (illustrative)
STT/CTT applies to equities and derivatives at product-specific rates, commonly 0.1% on equity delivery and a lower rate on intraday sells per current schedules.
SEBI turnover fee is charged by value traded, historically expressed per crore of turnover and included in broker schedules.
Exchange transaction charges (NSE/BSE) apply as a percentage of turnover and vary by segment and venue.
GST often applies at 18% on the sum of brokerage plus certain charges, as reflected in brokerage calculators and schedules.
Stamp duty is levied by states on the buy side for equities with segment-wise rates, typically small but non-trivial for large trades.
The tool’s itemized inputs mirror brokerage calculators and fee schedules so users can reflect current rates from their broker or exchange.
U.S. examples (illustrative)
FINRA Trading Activity Fee (TAF) applies on equity sales on a per-share basis with a per-transaction cap, passed through by brokers.
SEC Section 31 transaction fee rate for most securities transactions is set periodically and, for FY2025 after May 14, 2025, is $0.00 per million for covered sales until further notice.
Some brokers pass through consolidated audit trail (CAT)–related cost recovery on a per-executed-share basis as disclosed in support articles.
These regulatory pass-throughs are sale-side and small per share but should be captured for precise net P&L, which the calculator supports.
How to use the calculator
Enter buy price, sell price, and share quantity to compute gross P&L and percentage return immediately.
Add optional costs: brokerage/commission, exchange fees, STT/TAF, GST/other taxes, stamp duty, and any dividends received to see Net P&L.
Toggle breakeven to solve for the minimum sell price required to cover costs or set a target profit to find a required sell price.
A clear, mobile-optimized flow with immediate feedback supports fast decision-making and aligns with Core Web Vitals guidance.
Worked example (illustrative)
Consider 100 shares bought at ₹200 and sold at ₹230 with ₹50 total buy-side costs and ₹60 total sell-side costs, no dividends.
Gross P&L: (230−200)×100=₹3,000, Net P&L: ₹3,000−(₹50+₹60)=₹2,890, Return% (nominal): 230−200200×100=15%.
If the goal is to breakeven with the same fee structure, breakeven sell price per share is 200+50+60100=₹201.10.
If a 10% nominal profit is desired, target sell is 200×1.10+50+60100=₹221.10, before considering taxes on gains.
Portfolio context: cost basis and FIFO
Average share price after multiple acquisitions follows weighted averaging to produce an accurate cost basis for return calculation.
Many Indian broker portfolios compute realized P&L with FIFO, meaning earlier lots are assumed sold first, influencing realized gains and tax lots.
The calculator’s average price and lot-aware notes help align ad-hoc computations with portfolio methods used by broker platforms.
FAQs
How is stock profit calculated here?
Gross profit is (Sell−Buy)×Qty and net profit subtracts fees and taxes while adding dividends for a complete picture.
Does the calculator include brokerage and regulatory fees?
Yes, itemized fields capture brokerage, exchange fees, STT/TAF, GST/other taxes, and stamp duty so net P&L reflects actual trading frictions.
What fees are common in India?
Typical components include brokerage, exchange charges, SEBI turnover fees, STT/CTT, GST on charges, and stamp duty, which vary by segment and venue.
What fees apply in the U.S.?
FINRA TAF applies on equity sales per share, and SEC Section 31 fee rates are set by advisory (currently $0.00 per million for most covered sales after May 14, 2025, until further notice).
Can it compute breakeven and target sell price?
Gross profit is (Sell−Buy)×Qty and net profit subtracts fees and taxes while adding dividends for a complete picture.
How is average price handled for multiple buys?
Average cost uses weighted average of prices by quantity, and FIFO notes help align with broker portfolio realizations.
