Trading Risk Calculators
Size, liquidation and risk — worked out before the trade, with the assumptions behind every number shown rather than hidden.
Liquidation Price Calculator
The mark price where an isolated or cross position gets closed out — with the formula, the assumptions and the reasons it can differ from your exchange.
Open →Position Size Calculator
Decide the most you are willing to lose first, then let that set the size. Fees and slippage come out of the risk budget, and the stop is checked against liquidation.
Open →PnL & Breakeven Calculator
Gross versus net, ROE and ROI, and the exit price you actually break even at once both fee legs and funding are paid.
Open →Leverage Risk Comparison
The same trade at 2x, 5x, 10x and 20x side by side — what leverage changes (margin, room before liquidation, ROE) and what it does not (the PnL of the move itself).
Open →Stop-Loss & Risk/Reward
Whether the stop can execute at all in front of liquidation, then the reward-to-risk ratio net of costs and the win rate it would take just to break even.
Open →Funding Cost Calculator
What a small rate every eight hours really costs to hold — counted at the settlements you actually cross, not prorated by the minute.
Open →Average Entry & Add-Ons
Simulate adding to a position: the new average, the effective leverage, and a re-solved liquidation price — with the better average and the smaller buffer reported as the separate results they are.
Open →Liquidation Screenshot Replay
Load a position screenshot, confirm what it says, and re-price it — then find out why the exchange liquidated where it did, by solving backwards for the rate or the margin that explains the gap. The image is read in your browser and never uploaded.
Open →Maximum Risk Calculator
The quick one: account balance and a risk percentage, and the most a single trade may lose.
Open →Educational tools, not investment advice.
