Choose the invalidation first
A calculator cannot decide where the setup becomes invalid. Use market structure for that decision, then check whether the resulting loss fits your budget.

A stop price should connect the chart to your account risk
A chart level tells you where a trade idea is wrong. A loss budget tells you how much the account can afford to lose. This calculator connects the two using your actual position size and execution costs.
Measure the full exit
The price move is only part of the loss. Entry fees, stop fees, and a worse market fill also consume the budget.
Reverse the calculation
If the position size is already known, Calcoring can solve the trigger price that targets a chosen account loss.
Solve from the expected execution—not only the trigger
A stop-market order is triggered at one price and may execute at another. Calcoring first reserves entry and stop fees, models an adverse fill, and then solves the remaining price distance.

Risk budget = Account balance × Risk %02
Long estimated fill = Stop trigger × (1 − Slippage %)03
Short estimated fill = Stop trigger × (1 + Slippage %)04
Net stop loss = Price loss + Entry fee + Stop feeThe stop trigger is not a guaranteed fill price
When a stop triggers a market order, the order consumes available liquidity. In a fast move or thin order book, the average fill can be worse than the trigger. Trigger basis also matters: last price, mark price, and index price may reach the level at different times.
- Use a larger slippage buffer for volatile or less liquid markets.
- Check which reference price triggers the stop on your exchange.
- Keep the protective stop above the liquidation level for a short and below it for a long, with room for trigger differences.
- A stop-limit order controls price but may remain partially or completely unfilled.
A $100 BTC loss budget on a $5,000 position
Assume a $10,000 account, 1% maximum risk, a $68,000 long entry, and $5,000 position notional. With a 0.02% entry fee, 0.05% stop fee, and 0.05% adverse slippage, the stop must be closer than a formula that ignores costs.
Account risk$10,000 × 1% = $100
Position notional$5,000

Entry fee$1.00

Modeled net lossAbout $100
Execution reference: Bybit documents that market orders can slip, stop triggers and execution prices can differ, and the final fill depends on available order-book liquidity. Bybit Help Center
Stop-loss questions
What is a stop-loss calculator?
It estimates either the stop price needed for a chosen loss budget or the expected loss from a stop you already selected. It does not choose the correct technical invalidation level for you.
Should I set risk before position size?
Usually, choose the invalidation level and account risk first, then calculate position size. This reverse tool is useful when the position is already known or when checking an exchange order before submission.
Why is the calculated stop closer after adding fees?
Fees consume part of the same loss budget. Less of the budget remains available for the price move, so the trigger must move closer to entry.
Does leverage change the stop price?
Not directly when entry price, position quantity, and loss budget stay the same. Leverage changes required margin and liquidation risk, so the stop must still be checked against the liquidation level.
Will my stop execute at the trigger price?
Not necessarily. A stop-market exit prioritizes execution, and its average fill can be worse. A stop-limit order adds price control but can fail to fill.
Can a stop prevent every large loss?
No. Gaps, insufficient liquidity, exchange outages, order rejection, and liquidation before the selected trigger can all produce a larger loss.
