Risk budget
Choose a percentage of account balance or a fixed maximum loss for this trade.
Turn account risk and stop distance into a fee- and slippage-aware position size, then compare the stop with estimated liquidation.
Fees and the slippage buffer are included in the risk budget. Presets are editable starting rates; actual fees and fills can differ.
Position sizing starts with the account loss you are willing to accept—not the leverage offered by an exchange. Calcoring divides that budget by loss per asset unit, then reserves part of it for fees and adverse stop slippage.
Choose a percentage of account balance or a fixed maximum loss for this trade.
A tighter stop creates a larger position for the same risk budget; a wider stop creates a smaller one.
Leverage changes the collateral required to open the result, not the price loss at the stop.
The calculator models a linear USDT-margined position. It moves the estimated stop fill beyond the trigger by the selected slippage buffer, then includes entry and exit fees in the same risk budget.
Risk budget = Account balance × Risk percentageLoss per unit = |Entry − Estimated stop fill| + Entry fee per unit + Stop fee per unitPosition quantity = Risk budget ÷ Loss per unitRequired margin = Entry notional ÷ LeverageOnce entry, stop, and quantity are fixed, leverage only changes the initial margin required. It does not reduce the loss between entry and stop. Fees are charged on filled position value and can vary by order type and account tier.
A $10,000 account risks $100. With entry at $65,000, stop at $63,700, a 0.10% stop slippage buffer, 0.02% maker entry fee, and 0.05% taker stop fee, the position is about 0.071 BTC or $4,615 notional. At 5x it needs about $923 margin.
The calculator does not prescribe one. Choose a limit that fits your strategy, loss tolerance, portfolio concentration, and the possibility of several losing trades in sequence.
Less loss is expected per asset unit, so more units fit inside the same dollar risk budget. Tight stops can be hit more often and are more sensitive to slippage.
No. Position size comes from risk budget and stop distance. Higher leverage only reduces the margin needed to open that same notional.
If the full risk budget is allocated only to the price move, opening and closing fees push the possible loss above the amount you selected.
No. A stop is an execution instruction, not a guaranteed fill price. Gaps, thin liquidity, slippage, outages, and liquidation can produce a larger loss.
