Crypto Position Size Formula Used by This Tool
Linear Contracts (USDT-Margined)
Price Distance = Entry Price − Stop-Loss Price
Position Size (contracts) = Risk Amount ÷ Price Distance
Inverse Contracts (Coin-Margined)
Price Distance = Entry Price − Stop-Loss Price
Position Size (contracts) = (Risk Amount × Entry Price) ÷ Price Distance
Risk Amount = Account Balance × (Risk% / 100)
Total Exposure = Position Size × Entry Price
Required Margin = Total Exposure ÷ Leverage

Frequently Asked Questions
What is the difference between linear and inverse contracts?
Linear contracts (USDT-margined) use USDT as collateral and have linear PnL. Inverse contracts (Coin-margined) use the cryptocurrency itself as collateral and have inverse PnL.
How is position size calculated for linear contracts?
Position Size = Risk Amount ÷ (Entry Price − Stop-Loss Price). Each contract is worth $1 (or your contract size).
How is position size calculated for inverse contracts?
Position Size = Risk Amount × Entry Price ÷ (Entry Price − Stop-Loss Price). This accounts for the inverse PnL formula.
What is required margin?
Required Margin = Total Exposure ÷ Leverage. This is the minimum amount of collateral required to open the position.
