Why Use Trading Calculators?
Trading in the Indian stock market requires precise calculations for risk management, position sizing, and profitability analysis. Our free trading tools are designed specifically for NSE and BSE traders, with support for equity, F&O, and commodity trading.
Position Sizing & Risk Management
Proper position sizing is the cornerstone of successful trading. Our position size calculators help you determine the optimal number of shares or lots to trade based on your account size and risk tolerance. Whether you're trading Nifty options or Bank Nifty futures, these tools ensure you never risk more than you can afford to lose.
Options Trading Calculators
Options trading in India has grown significantly, especially with weekly expiries on Nifty (NSE) and Sensex (BSE). Bank Nifty has monthly expiries only. Our options calculators help you analyze strategies like iron condors, straddles, strangles, and spreads. Calculate breakeven points, maximum profit/loss, and required margin before entering any trade.
Brokerage & Cost Analysis
Understanding your true trading costs is essential for profitability. Our brokerage calculators support major Indian brokers including Zerodha, Groww, Angel One, and Upstox. Calculate STT, GST, stamp duty, exchange transaction charges, and SEBI fees for any trade.
Tax Calculators for Traders
Navigate India's complex tax rules for trading income with our tax calculators. Whether you're dealing with STCG, LTCG, F&O business income, or speculative income from intraday trading, our tools help you estimate your tax liability and plan accordingly.
Most used trading calculators for F&O traders
With so many calculators on this page, it helps to know where most traders start. These eight cover the questions that come up before, during and after almost every F&O trade:
- Nifty position size calculator: how many lots fit inside the loss you have decided you can accept.
- Risk per trade calculator: turns a percentage of your capital into a rupee loss limit.
- F&O trading cost calculator: adds up brokerage and statutory charges on a trade so you see the cost before you enter.
- STT calculator: works out securities transaction tax for a given trade.
- Options profit calculator: shows the profit or loss of an option position at different prices.
- Options breakeven calculator: finds the price the underlying must reach for the position to cover its cost.
- Risk reward calculator: compares what you stand to lose with what you aim to gain.
- F&O income tax calculator: gives an estimate of tax on F&O income. Check the final figure with a chartered accountant (CA).
Which calculator do I need? A quick guide
Pick by the question you are asking, not by the tool name. This list follows the life of a trade.
Before you enter
Start with risk. Decide the most you are willing to lose on the trade, then use a risk per trade calculator and a stop-loss calculator to turn that into a stop level. Check the risk reward calculator to see if the target is worth the stop. For options, the breakeven calculator shows how far the underlying must move before you are even.
Sizing the trade
Position size follows from the stop distance and your loss limit. The Nifty position size calculator and the stock position size calculator do this arithmetic. Lot sizes are set by the exchange and they change, so confirm the current lot size on the lot size reference table and with your broker. Margin needed is a separate question, and the futures margin calculatoris the place to start. Your broker's own margin figure is the one that counts.
Understanding costs
Costs matter most for small, frequent trades. The total trading cost calculator, F&O trading cost calculator, STT calculator and GST on brokerage calculator break the bill into its parts. For how brokers differ, see our broker comparison.
Options analysis
The options Greeks calculator shows how an option's value may change with price, time and volatility. The options profit calculator and expiry day calculator help with payoffs near expiry.
Tax
Use the F&O income tax calculator and turnover calculator for tax audit to get a rough idea. Tax rules and thresholds change, so use these for planning only and check the final numbers with a CA.
After the trade
A calculator answers one question about one trade. To see patterns across many trades, check the profit factor calculator and the maximum drawdown calculator, or keep a record in your trading journal.
How our calculators handle Indian charges and lot sizes
Charges in India are made of brokerage, exchange transaction charges, securities transaction tax (STT), SEBI turnover fees, stamp duty and GST. Exchange and statutory rates are the same for every broker. Brokerage is what differs. Our dated record of rate changes, with the circular and effective date for each, is in the trading charges log, last checked on 13 October 2026. New STT rates took effect on 1 April 2026.
Lot sizes and expiry days are set by NSE and BSE, and they have changed before. NSE index expiry day is Tuesday and BSE is Thursday, and only Nifty (NSE) and Sensex (BSE) have weekly expiries. The other indices have monthly expiries. If a holiday moves an expiry, the usual weekday rule stays, but that month's actual date shifts. Do not depend on any calculator, ours included, for the final lot size or expiry date of an order. Check the exchange circular or your broker's contract list.
Many calculators on the web replace a blank or zero input with a default value without saying so. If an output looks odd, check that every field has a real number. Also treat sample values in any calculator as examples, not suggestions.
Calculators by market: Nifty, Bank Nifty, stocks, MCX, forex and crypto
The maths of a trade depends on the market. A Nifty option is sized in lots, a share is sized in whole quantities, a forex pair is measured in pips and a crypto position can be liquidated by a margin call. If you already know which market you trade, start with the tools made for it. Check every result against your broker, because lot sizes, margins and charges can change.
Nifty and Bank Nifty
For index options and futures, the Nifty position size calculator, Nifty options premium calculator and Nifty fair value calculator cover sizing, premium and futures pricing. For Bank Nifty there are the Bank Nifty lot size calculator and the Bank Nifty straddle calculator. The GIFT Nifty gap calculator helps you see how far the market may open from the last close. Always confirm the current lot size with NSE before you place a trade.
Stocks and intraday equity
For shares, use the stock position size calculator to turn your risk limit into a quantity and the stock profit calculator to see profit or loss after you enter a buy and sell price. Intraday traders can compare costs with the intraday vs delivery cost comparison and estimate tax with the intraday trading tax calculator. If a company announces a split or bonus, the stock split and bonus calculator shows how your holding changes.
MCX commodities and currency
Commodity and currency trades carry their own charges. The MCX commodity trading cost calculator and the currency trading cost calculator add up brokerage and statutory costs for those segments. Contract sizes and quote units differ by commodity and currency pair, so read the contract specification before relying on any figure.
Forex
For forex, the forex pip calculator, forex position size calculator, forex margin calculator, forex profit calculator and forex swap calculator cover pip value, size, margin, result and overnight cost. The forex compounding calculator shows how returns could build up over time, using the rate you enter, which is not a promise of future results. In India, retail forex rules are restrictive, so check which pairs and routes your broker is allowed to offer before trading.
Crypto
Crypto traders can use the crypto position size calculator, crypto profit calculator, crypto futures PnL calculator, crypto liquidation calculator and crypto funding rate calculator. For longer-term buyers there are the crypto DCA calculator and crypto average calculator. For tax in India, see the crypto tax calculator for India. All of these are grouped on the crypto calculators page. Tax rules change, so confirm with a chartered accountant.
