Liquidation mechanics on Deribit
This calculator's formula models isolated margin: the standard way to size a single position's liquidation risk on its own. If your account runs cross margin instead, your real liquidation price also depends on your other positions and total account balance, not just this one. Check your Deribit account settings for your current margin mode.
When your equity falls below the maintenance margin requirement, Deribit's risk engine triggers liquidation, forcibly closing the position to prevent a negative balance.
Maintenance margin rates for major pairs are typically around 0.5% across most exchanges, rising in tiers as position size grows. The formula below simplifies this to a flat 0.5% for readability: for a long position, liquidation price ≈ entryPrice × (1 − 1/leverage + 0.005). At 50× maximum leverage this means even a tiny adverse move can trigger liquidation, which is why most experienced traders use 5–20× rather than the maximum.
Deribit also has an "auto-deleveraging" (ADL) system for extreme scenarios where the insurance fund is insufficient. In practice, staying well above your liquidation price eliminates ADL risk entirely.
Deribit fee structure
Deribit charges maker fee −0.01% (rebate) and taker fee 0.05% on perpetual futures. Maximum available leverage is 50×. This calculator pre-fills these defaults so you get accurate results without needing to look up the fee schedule. If you are on a VIP tier with discounted fees, adjust the fee fields accordingly.
Maker orders (limit orders that add liquidity) cost less than taker orders (market orders that remove liquidity). On Deribit, using limit orders for both entry and exit can reduce your total fee cost significantly compared to market orders.
