Determine how large a trade you should take based on your account size, risk tolerance, stop-loss distance and leverage.
Position sizing is the single most important risk-management technique for traders. It tells you how much capital to allocate to a trade so that a single loss cannot significantly damage your account. Consistent position sizing preserves capital and lets you trade another day.
The calculator follows these steps:
1. Enter your total account balance in USD.
2. Choose the percent of your account you are willing to risk on this trade (commonly 0.5%–2%).
3. Enter the entry price and the stop-loss price (where you'll exit if the trade is wrong).
4. Choose leverage (1 = no leverage).
5. Select direction (Long or Short).
6. Click Calculate. The tool shows risk amount, position size (USD), units to buy/sell, and required margin.
Account = $5,000, Risk = 1% → Risk Amount = $50. Entry = $25,000, Stop = $24,000 → Price Risk = $1,000 per BTC (4%).
Position Size = $50 / $1,000 = 0.05 BTC → in USD: 0.05 × 25,000 = $1,250. If leverage = 5x, required margin = $1,250 / 5 = $250.

Many experienced traders risk between 0.5% and 2% of their account per trade. The exact amount depends on your strategy, edge, and psychological comfort. Start conservatively while you refine your system — small, consistent risks preserve capital and let you survive losing streaks.
Leverage increases your exposure for a smaller margin. This calculator gives a position size in USD (the full exposure). Required margin = Position Size ÷ Leverage. Higher leverage narrows the price buffer to liquidation — use it carefully and calculate liquidation risk using the Liquidation Price Calculator.
If market conditions change and your stop-loss is no longer valid, you should reassess the position. A prudent approach is to either adjust your stop-loss with a justified rule or close the position. Position sizing is only one part of risk management and must be paired with disciplined trade review.
The calculator focuses on price risk and position sizing. Fees reduce net profit and can influence stop placement; we recommend adding estimated fees into your risk calculation or increasing the risk percent slightly to cover fees if needed.
Basic logic is the same (risk amount ÷ price risk), but futures often involve leverage and funding costs. Always consider leverage, margin, funding rates, and liquidation rules when sizing futures positions.
