Your stop and your fees set the size. Leverage only sets the margin.

Enter balance, risk %, entry, stop, both fees and leverage. The calculator returns the units that keep price loss plus fees inside your budget, and shows notional and margin separately from your capital.

Size the position from the loss you accept

Defaults are a labeled hypothetical: $1,000 balance, 1% risk, $100 entry, $98 stop, 0.055% fee on each fill and 1x leverage. Replace them with your own numbers.

Direction

The share of the balance you accept losing if the stop fills.

Changes margin only. It does not change the risk budget or the position size.

Fees are yours to edit; 0.055% is a hypothetical example, not your quote. Published references checked 2026-10-28: Bybit lists 0.055% taker / 0.02% maker per fill for non-VIP derivatives, and actual rates can vary by region and account. OKX shows a regular-user futures example of 0.05% taker / 0.02% maker; verify your account and instrument. No universal Binance rate is assumed here. Use the rate your own account shows.

Position size 4.7418 units, entry notional $474.18, total planned loss $10.00.

Position size at your stop

4.7418 units

Entry notional $474.18 · margin at 1x about $474.18. Notional is the position's size, margin is the collateral locked, and neither is the amount you planned to lose.

FAQ

How is position size calculated with fees?

Units = risk budget ÷ (|entry − stop| + entry × opening fee + stop × closing fee). With a $1,000 balance, 1% risk, a $100 entry, a $98 stop and 0.055% per fill, that is about 4.7418 units: about $9.48 of price loss plus about $0.52 of fees, or $10.00 in total.

Does leverage change how much I can lose?

Not in this calculation. The risk budget and the stop set the position size. Leverage only changes the margin locked for that position. Higher leverage moves the liquidation price closer, which this tool does not model.

Why can my real loss be bigger than the planned loss?

A stop is an order, not a guarantee. Slippage, spread, price gaps, partial fills, funding, liquidation and maintenance-margin rules, mark-price triggers and tax are all outside this estimate.

Which fee should I enter?

The rate your own account shows for that exact product and order type. A stop that executes as a market order is usually charged the taker rate. The 0.055% default is a hypothetical example.
