Professional-grade trading calculators for crypto perpetual futures. Calculate position size, liquidation price, profit and loss, risk/reward ratios, funding costs, and more. All tools are free, no signup required.
Blackperp provides 12 free, professional-grade trading calculators built specifically for crypto perpetual futures traders. Whether you trade on Binance, Bybit, or OKX, these tools help you make precise, data-driven decisions before every trade.
Position sizing is where most retail traders fail. Our position size calculator converts your risk tolerance into exact contract amounts, ensuring you never over-expose on any single trade. Pair it with the liquidation price calculator to verify your stop loss sits well above your liquidation level, and the risk/reward calculator to confirm the trade offers positive expected value.
For longer-duration trades, the funding cost calculator projects cumulative funding payments that can erode profits over hours, days, or weeks. The PnL calculator accounts for entry and exit fees, funding costs, and leverage to show true net profit or loss — not just gross price movement.
All calculators work in your browser with no signup, no data collection, and instant results. 173 signals | 25 categories | funding rates
Yes, all calculators are completely free to use with no signup required. They are professional-grade tools designed for perpetual futures traders, covering position sizing, liquidation prices, profit/loss, risk/reward ratios, funding costs, margin requirements, DCA planning, and more.
The liquidation calculations use the standard formulas for isolated and cross margin positions. However, actual liquidation prices on exchanges like Binance, Bybit, and OKX may differ slightly due to additional fees, insurance fund contributions, and tiered maintenance margin rate schedules. Always verify the liquidation price shown on your exchange before trading.
Yes. The calculators support customizable fee rates, leverage limits, and maintenance margin rates for all major exchanges. We provide exchange-specific versions with pre-filled fee tiers and leverage schedules for Binance, Bybit, and OKX perpetual futures.
Use the position size calculator: enter your account balance, the percentage you want to risk (1-2% recommended), your entry price, and your stop loss price. The calculator determines the exact position size in USDT and contracts. This ensures each trade risks a controlled amount regardless of the asset or leverage used.
Gross PnL is the raw profit or loss from price movement alone. Net PnL subtracts all costs: trading fees (typically 0.04-0.05% per trade on Binance), funding rate payments (charged every 8 hours), and any additional exchange fees. For positions held over multiple funding intervals, the net PnL can be significantly lower than gross PnL.
