Funding rates on Polymarket Perps

This calculator fetches actual historical Polymarket Perps funding rates for the selected instrument and sums the exact cost for your holding period, not an estimate. Enter the date you opened your position and the calculator accounts for every funding interval from then to now.
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.

View API & MCP docs →What is a funding rate?
Funding rates are periodic payments between long and short traders to keep perpetual futures prices anchored to the spot market. Paid every 8 hours on most exchanges.
When does funding cost become significant?
Funding accumulates over time. On an hourly schedule, even a tiny per-period rate compounds faster since there are 24 payments a day instead of 3. On a large leveraged position this adds up quickly.
What assumptions and edge cases does this calculator use?
Size, entry price and days must be above zero. The funding rate is a fraction per interval (0.0001 is 0.01 percent) and can be negative, and the interval is 0.25 to 24 hours (default 8). If funding costs more than the whole position is worth you get an error. Not covered: a funding rate that changes during the hold, and price moves.
