Polymarket Perps Fee Calculator
Work out the fee on any Perps position. Perps are charged on notional value and tiered by your trailing 30-day volume — a completely different model from prediction markets.
Perps fees are tiered by trailing 30-day trading volume, re-evaluated every UTC day. New accounts start at the $0 tier. Taker crosses the spread; maker rests on the order book.
Charged per fill on notional value: fee = abs(Price × Quantity) × Rate. Denominated in pUSD.
At 10× leverage this notional represents about 1,000.00 pUSD of posted margin. Leverage widens the notional the fee applies to, and the fee is charged on notional, not on margin.
Maker fees are positive at lower tiers and become a rebate at the top tier — the fee recipient is debited by the same amount.
What this trade costs at every tier
| 30-Day Volume | Taker Fee | Maker Fee |
|---|---|---|
| $0 · You | 4.00 (0.0400%) | 1.25 |
| $1M | 3.70 (0.0370%) | 1.00 |
| $5M | 3.50 (0.0350%) | 0.80 |
| $25M | 3.00 (0.0300%) | 0.50 |
| $100M | 2.70 (0.0270%) | 0.20 |
| $500M | 2.50 (0.0250%) | 0.00 |
| $1B | 2.00 (0.0200%) | +0.50 |
Polymarket Perps uses a different fee model from prediction markets: fee = abs(Price × Quantity) × Rate, tiered on trailing 30-day volume. Base tier: 0.0400% taker, 0.0125% maker. Top tier: 0.0200% taker, -0.0050% maker. Fees are denominated in pUSD and re-evaluated every UTC day.
Prediction-market fees use a different formula (C × feeRate × p × (1 − p), price-dependent). Use the standard fee calculator for those.

How Polymarket Perps Fees Work
Perps fees work differently from prediction market fees. They are charged on the notional value of each trade:
fee = abs(Price × Quantity) × RateBecause the fee is a flat percentage of notional, it scales linearly with position size. That means the effective rate is identical at every price and every size — unlike prediction markets, where the effective rate falls as the share price rises.
The rate itself is set by your account’s trailing 30-day trading volume, and tiers are re-evaluated every UTC day. New accounts start at the base tier.
Fee Tiers
| 30-Day Volume | Taker | Maker |
|---|---|---|
| $0 | 0.0400% | 0.0125% |
| $1M | 0.0370% | 0.0100% |
| $5M | 0.0350% | 0.0080% |
| $25M | 0.0300% | 0.0050% |
| $100M | 0.0270% | 0.0020% |
| $500M | 0.0250% | 0.0000% |
| $1B | 0.0200% | −0.0050% (rebate) |
Fees are denominated in pUSD.
The Maker Rebate
Maker rates start positive and fall as you climb the tiers. From the $500M tier the maker rate reaches zero, and at the $1B tier it turns negative: makers receive 0.0050% of notional rather than paying it. Internally the fee recipient’s ledger is debited by the same amount, so the rebate is genuinely funded rather than a discount.
If you are consistently posting resting liquidity, the top tier is the point where market making on Perps flips from a cost into a small income stream on top of your spread capture.
Leverage, Margin and Why Notional Matters Most
Perps support up to 20x on crypto, the S&P 500, oil, gold and silver, and up to 10x on other real-world assets. Some markets are isolated-margin only and reject cross margin. Maintenance margin is flat per market at 0.5 ÷ max leverage — 2.5% on a 20x market — which means a maximum-leverage position is liquidated after losing roughly half its posted margin.
This matters for fees in a way that catches people out. Fees are charged on notional, not on the margin you post. A $10,000 position at 10x leverage uses $1,000 of margin but still attracts a fee on $10,000 of notional. At the base tier that is $4.00; the same notional at the top tier costs $2.00. If you size purely by the capital you’re willing to commit and then apply leverage, your fee bill scales with the leverage, not the deposit.
Funding Payments
Funding keeps the contract price tethered to the underlying. A premium index is sampled every 5 seconds by walking the book for 1,000 of quote-asset notional on each side, averaged over a one-hour window, then run through an eight-hour formula and capped at ±4% per hour. Settlement happens once per window, and the protocol takes no cut — funding is a transfer between longs and shorts, not a fee.
Where Perps Differs From Prediction Markets
| Prediction markets | Perps | |
|---|---|---|
| Fee basis | C × feeRate × p × (1 − p) | abs(Price × Quantity) × Rate |
| Driven by | Price and category | Notional and 30-day volume |
| Effective rate | Falls as price rises | Constant (equals the tier rate) |
| Maker treatment | Always $0, plus a share of taker fees | Positive at low tiers, rebate at the top |
| Settlement | $1.00 or $0.00 at resolution | Continuous, marked to market |
| Expiry | Resolves on an event | None |
Because the two models are unrelated, the standard Polymarket fee calculator does not apply to Perps — use the calculator above for Perps and the other one for prediction markets.
Geographic Limits
Perps order placement is not permitted from the United States, Canada, Cuba, Iran, North Korea, Syria, Crimea, Donetsk or Luhansk. Read-only market data is unrestricted.
⚠️ This list is different from Polymarket’s prediction-market restrictions. Canada is the clearest example: Perps order placement is blocked nationwide, while prediction markets are only close-only in British Columbia, Ontario, Alberta and Quebec. Check the country availability guide for the prediction-market picture and treat Perps separately.
