This free stop-loss and take-profit calculator turns one number, the percentage of your account you are willing to lose, into a complete trade plan.
Enter your balance and risk, pull a live price, and you instantly get your exact position size, a volatility-based stop loss, the required isolated margin, and 2R and 3R take-profit targets. It works for Bitcoin, Ethereum, Solana and every other USDT pair, on spot or leveraged futures.
Most blown accounts do not come from bad entries. They come from position sizes that are too big for the stop. Sizing by feel means one normal losing streak can wipe out weeks of gains. Sizing by a fixed percentage of equity keeps every loss small and survivable, so you stay in the game long enough for your edge to play out.

How the position size is calculated
Professional risk management is built on one rule: decide what you can lose before you decide how much to buy. The math behind this tool is simple and fully transparent.
Because the position size is derived from the stop distance, your dollar risk stays the same whether you trade a calm large-cap or a volatile low-cap. The size shrinks automatically when the stop is wider, which keeps your portfolio consistent across very different setups.
Why a 2× ATR stop loss?
ATR (Average True Range) measures how much an asset actually moves on a given timeframe. A stop placed at 2× ATR sits beyond the market's normal noise, so you are far less likely to get wicked out of a good trade by a random spike, while still cutting the position fast when price genuinely turns against you. Tighten or widen the timeframe to match your style: 15m to 1h for intraday, 4h to 1D for swing trades.
How much should you risk per trade?
A common guideline among experienced traders is 1% to 2% of account equity per trade. This calculator lets you set anything from 1% to 100%, but more risk means a single bad run can do real damage. At 1% risk you can lose 20 trades in a row and still keep around 80% of your account. At 10% the same streak nearly empties it.

Frequently Asked Questions
How do I calculate position size from risk percentage?
Multiply your account balance by your risk percentage to get your dollar risk, then divide that by the distance from entry to stop loss. The result is the number of units to buy. This calculator does it for you and adds leverage and take-profit on top.
Is this stop-loss and take-profit calculator free?
Yes. It is completely free, needs no sign-up, and works for any crypto pair. Live prices and ATR are fetched straight from the exchange in your browser.
What is a 2R or 3R take-profit?
R is your initial risk, the amount you lose if the stop hits. A 2R target makes twice that risk and a 3R target three times. Aiming for 2R or more means you can be right less than half the time and still grow your account.
Does it work for leveraged futures?
Yes. Your position size is set by your risk and stop, independent of leverage. Leverage only changes the margin you lock up, shown as Required margin for isolated mode up to 125×.
Can I use it for long and short trades?
Yes. Toggle Long or Short at the top and the stop-loss and take-profit prices flip to the correct side of your entry automatically.
