Formulas used
- Risk amount = balance × risk%
- Quantity = risk amount ÷ |entry − stop|
- Notional = quantity × entry · Margin = notional ÷ leverage
- Net PnL = direction × (exit − entry) × qty − fees(in + out)
- Liq (long) ≈ entry × (1 − 1/lev + maint% + fee%)
- Safe lev = 1 ÷ (stop% + buffer% + maint% + fee%)
- Breakeven win rate = 1 ÷ (1 + R:R)
FAQ
Straight answers, no hedging.
What is a crypto futures calculator?
A tool that computes the numbers you should know before entering a leveraged trade: position size from your risk budget, estimated liquidation price, profit and loss after fees, risk/reward ratio, and a leverage level that keeps liquidation safely beyond your stop loss.
How do I calculate crypto position size?
Decide the dollar amount you are willing to lose (account balance × risk %), then divide it by the distance between entry and stop loss. That gives the quantity; quantity × entry price is your notional position, and notional ÷ leverage is the margin you must post.
How is liquidation price estimated?
For an isolated USDT linear perpetual, the estimate moves the entry price against you by roughly 1/leverage, adjusted for maintenance margin and fees. Long: entry × (1 − 1/leverage + maintenance% + fee%). Exact values differ by exchange and account settings.
Is this exact for Binance, Bybit, OKX, or Bitget?
No calculator outside the exchange can be exact. Liquidation and margin depend on the venue's maintenance-margin tiers, margin mode, funding, fees, and any position changes. These figures are close estimates for isolated USDT linear perpetuals — always confirm on your exchange before trading.
What is a safe leverage level?
One where your estimated liquidation price sits beyond your stop loss with a buffer — so the stop, not the exchange, closes your losers. This calculator solves for that level from your stop distance, maintenance margin, fees, and a configurable buffer.
Does this calculator give trading advice?
No. Every output is general market and risk education — not financial advice, investment advice, or a recommendation to trade. What you do with the numbers is your decision and your responsibility.
