How they fit together
A trade plan has four questions in it. The position size calculator answers how much to buy so a stop-loss costs only what you chose to risk. The risk-reward calculator tells you whether the target pays enough for that risk and what win rate you need. If the trade uses leverage, the liquidation price calculator checks the exchange will not close it before your stop does. Afterwards, the futures P&L calculator shows what the trade actually made once fees and funding are taken out.
All four run in your browser with nothing sent to a server. The inputs are stored in the page URL, so Copy link gives you a URL that reopens the same setup.
Calculator FAQ
Are these calculators free?
Yes. Every tool on this page is free to use without an account. They run in your browser, and the inputs are only stored in the page URL so you can copy a link and share a setup.
Which calculator should I use before a trade?
Start with the position size calculator to turn your risk per trade into a number of units. Then check the risk-reward calculator to see whether the target justifies the stop, and the liquidation price calculator if you are using leverage. The futures P&L calculator is for reviewing a trade after the fact, or comparing exchanges' fees before you place it.
Do the calculators work for spot as well as futures?
Position size and risk-reward work for both - set leverage to 1 for spot. Liquidation price and futures P&L are specific to leveraged perpetual futures on exchanges such as Binance, Bybit and OKX.
Are the exchange fees and liquidation figures exact?
They are estimates. Fee presets are the default VIP 0 rates published by each exchange and can be edited; liquidation prices use a simplified maintenance-margin formula. Your exchange's order form shows the figure that actually applies to your account and tier.
