Frequently asked questions
How is the liquidation price calculated on Polymarket Perps?
Liquidation begins when account equity falls below maintenance margin, which Polymarket sets at notional × (0.5 ÷ the market's max leverage) — 2.5% of notional on a 20x market. For a long, the estimated liquidation price is entry × (1 − 1/leverage + maintenance rate); mirrored for shorts. Accrued fees and funding drain equity too, so real liquidation sits slightly closer than the estimate.
What are Polymarket Perps trading fees?
Base-tier fees are 0.0400% taker and 0.0125% maker, charged on notional per fill, with volume tiers stepping down to 0.02% taker and a maker rebate at $1B+ trailing 30-day volume. Because fees charge on notional, a 20x taker round trip costs about 1.6% of your collateral.
How does funding work on Polymarket Perps?
Funding settles every hour directly between longs and shorts, computed from how far the perp trades from its index price, and is capped at ±4% per hour. A positive rate means longs pay shorts; negative means shorts pay longs. This calculator projects costs from the current live rate — the actual rate recomputes hourly.
What leverage does Polymarket Perps allow?
Up to 20x on major crypto, index and commodity markets and up to 10x on single stocks (as of September 2026). Per-market risk tiers reduce the cap as position size grows — the calculator warns you when a position exceeds its tier's limit.
Can I trade Polymarket Perps from the United States?
No. Polymarket blocks Perps order placement in the United States and Canada per its official documentation. This calculator is informational and works anywhere. Circumventing geo-restrictions violates Polymarket's terms.
Formulas per docs.polymarket.com/perps as of September 2026: maintenance margin = notional × (0.5 ÷ market max leverage, per risk tier); fees charged on notional per fill; funding settles hourly, capped ±4%/hour. Estimates exclude accrued fees, accrued funding, the per-market liquidation fee and execution slippage. Parameters can change — the live app is authoritative.
