Using the Optimism Liquidation Price Calculator
Leverage on OP perpetuals turns a modest move into a total loss of margin. This calculator shows the OP price at which your position gets force-closed, given your entry, your leverage and which side you are on. The entry field starts at the live OP price so the distance to liquidation is a real number, not a hypothetical.
The rule of thumb: at N× leverage, roughly a 100/N percent move against you wipes the margin. At 10× that is about 10%; at 25× it is about 4%. OP competes directly with ARB for the same narrative, and the two tend to move together — often on the same rollup news. Compare that number honestly against the distance the calculator gives you before you place the order.
Two adjustments the raw formula does not make. Maintenance margin means liquidation triggers slightly before the theoretical zero — the field above lets you enter your exchange's rate. And on perpetuals you also pay funding, which slowly erodes margin on the crowded side of the trade and can pull the liquidation point closer over a long hold.

Frequently asked questions
- At what price does my OP long get liquidated?
- Approximately your entry price × (1 − 1/leverage), adjusted for maintenance margin. A 10× OP long is liquidated by roughly a 10% drop; a 20× long by roughly 5%. Enter your numbers above for the exact level.
- Does adding margin move the OP liquidation price?
- Yes — adding margin to an isolated position lowers effective leverage and pushes the liquidation price further away. In cross margin your whole balance backs the position, which moves the level further out but puts the rest of your account at risk.
- Why did I get liquidated before the price I calculated?
- Three usual reasons: maintenance margin bites before the theoretical level, accumulated funding payments have eaten into your margin, and exchanges liquidate against the mark price (an index) rather than the last trade on that one venue — a wick on a single exchange can differ.
- How is liquidation price calculated?
- For an isolated long: liq ≈ entry × (1 − 1/leverage + maintenance margin). Higher leverage moves liquidation closer to your entry.
- What is maintenance margin?
- It's the minimum equity the exchange requires to keep a position open. Falling below it triggers liquidation.
