Free Trading Calculators for India: Gain & Loss, CPR, Position Size, Forex Pip, SIP & Loan Tools

How a Trading Calculator Works: A Worked Example

A trading calculator turns a few inputs into numbers you can act on before you place the order. The sequence most Trading Direction students follow is simple: find the levels, set the stop, size the position, check the profit and loss on both sides of the trade, then confirm the net result after charges.

The same logic powers our Stop-Loss, Position Size and Option Selling calculators, adapted for stocks, options and commodities. For currency contracts the logic is identical but the unit changes: the Forex Pip Calculator converts ticks and pips into rupees and lots. Run the numbers first, and the trade you take is one you have already sized for the worst case.

Our Trading Calculator, Position Size and Stop-Loss calculators do this for you, and the worked example above shows the full calculation.

How do I find my net profit or loss after STT, brokerage and other charges?

Net result is the gross result, (sell price − buy price) × quantity, minus brokerage, STT, exchange charges, SEBI fee, stamp duty and GST. The Stock Trading Gain Loss Calculator does this for delivery, intraday, futures and options, and shows the break-even price. Charge rates differ by broker, so confirm them on your contract note.

What is a good Reward to Risk Ratio?

There is no official minimum. Many traders use 1:2 as a teaching guideline, which needs a win rate above about 33% before costs to break even. Test your own strategy to find the ratio that works for you.

Do you have a forex trading calculator?

Resident Indians can deal in forex only through authorised persons for permitted purposes under FEMA, so verify any platform on the RBI website before you open an account.

What is a CPR calculator and how is CPR calculated?

CPR (Central Pivot Range) is calculated from the previous day's High, Low and Close. Pivot = (H + L + C) ÷ 3, BC = (H + L) ÷ 2, and TC = (2 × Pivot) − BC. A narrow CPR is watched as a sign of a possible trending day, while a wide CPR often signals sideways movement.

Which calculator should a beginner start with?

If you're new to trading, start with the CPR Calculator and the CPR & Pivot Point Beginner's Guide. If you're new to investing, start with the SIP Calculator.

What is the difference between a SIP calculator and a lumpsum calculator?

A SIP calculator projects the value of a fixed monthly investment, optionally with an annual step-up. A lumpsum calculator projects the value of a single one-time investment. Use Goal SIP or Goal Lumpsum to work backward from a target amount.

Can I use these calculators for both stocks and NIFTY?

Yes. The Pivot Point Calculator is built for both NIFTY and individual stocks, and the Stop-Loss, Position Size and gain loss calculators cover options, stocks and commodities.

How do I calculate the breakeven and maximum loss of an option I buy?

For a call, breakeven is strike plus premium; for a put it is strike minus premium. Maximum loss is the premium paid times the quantity. Use the Options Buying Payoff Calculator to see both, plus the expiry payoff curve. Confirm the current lot size on NSE.

Brokerage is charged per order, STT applies to the buy and or sell value depending on the segment, and exchange charges and SEBI fee apply to turnover. GST applies to brokerage, exchange charges and SEBI fee, and stamp duty applies to the buy value. The Brokerage & Charges Calculator on this page does this with editable rates and shows the net result and break-even price.
