Liquidation mechanics on Polymarket Perps
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 Polymarket Perps account settings for your current margin mode.
When your equity falls below the maintenance margin requirement, Polymarket Perps'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) / (1 − 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.
Polymarket Perps 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.
Polymarket Perps fee structure
Polymarket Perps charges maker fee 0.0125% and taker fee 0.04% 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 Polymarket Perps, using limit orders for both entry and exit can reduce your total fee cost significantly compared to market orders.

View API & MCP docs →How is liquidation price calculated?
Liquidation price depends on your entry price, leverage and maintenance margin. For a long: liq ≈ entry × (1 − 1/leverage) / (1 − maintenanceMarginRate).
What happens when a position is liquidated?
The exchange forcibly closes your position when losses consume your margin. You lose the full margin used for that position.
What assumptions and edge cases does this calculator use?
Entry price and leverage must be above zero, the maintenance margin rate is a fraction from 0 to 0.2 (default 0.005), and a liquidation fee from 0 to 0.05 can be added. The flat rate is one rate you take from your exchange; for a tiered table give size and 1 to 50 tiers in ascending order, and a table that contradicts itself is refused. Not covered: auto-deleveraging, partial liquidation, mark price versus last price, funding paid while the position is open, and the exchange own engine, which may differ.
