Compounding funding income on Polymarket Perps
Polymarket Perps pays or charges funding every hour. Reinvesting that income back into your position (rather than withdrawing it) compounds your capital the same way reinvested interest does, at Polymarket Perps's prevailing rate.
Because Polymarket Perps settles funding 24 times a day, small rate differences compound faster than a daily or weekly funding schedule would. This calculator projects capital growth over your chosen holding period at a given reinvestment rate.
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.

Reinvesting perpetual futures funding income back into the position each interval, so subsequent earnings compound on a larger base instead of being withdrawn.
How is annualized APY calculated?
APY = ((Final Capital + Withdrawn) / Initial Capital)^(365 / Days) − 1, withdrawn funding counted as earned. Example on the common 8h funding schedule: a 0.01% rate with 100% reinvestment over 30 days yields roughly 11.6% APY - an hourly-funding exchange compounds on more, smaller periods per day instead.
What assumptions and edge cases does this calculator use?
Initial capital must be above zero. The funding rate is in percent per interval (0.01 is 0.01 percent), the interval is a whole number of hours that divides 24 (default 8), duration is above zero and at most 3650 days, and the reinvested share is 0 to 100 percent (default 100). The rate is assumed to stay constant. Not covered: a changing rate, fees, taxes and venue capital limits.
