Three crypto futures calculators, free and without sign-up.
Use them in order: set risk and position size first, check the distance to liquidation, then make sure the target is worth the risk. Each page shows its formula.
Free, no sign-upCrypto futures position size calculator
Decide what share of the balance you are willing to lose on one trade, then the position size follows the stop distance. Leverage only sets the margin locked, not how much you are risking.
Free, no sign-upCrypto futures liquidation price calculator
Liquidation happens when the position's loss eats the locked margin minus the exchange's maintenance margin. This calculator uses a simplified isolated-margin formula; the exchange figure can differ because of tiered maintenance margin, fees, and funding.
Free, no sign-upRisk-reward ratio and break-even win rate calculator
The risk-reward ratio compares the target distance with the stop distance. From it you can read how often you must be right just to break even, and whether your win rate is enough.
