Perpetual Futures Fee and Funding Calculator
Estimate maker and taker fees, funding payments and a potential weekly volume rebate. Free to use, with no signup.
Estimate the cost of a round trip
Enter position notional, not just margin. Choose the actual fill type for each side: a limit order that executes immediately may be a taker. These are estimates using the published TRUE fee schedule, reviewed 17 September 2026.
What the estimate includes
Opening fee = opening notional × opening fee rate. Closing fee = closing notional × closing fee rate. Estimated funding = opening notional × funding rate per interval × number of intervals, with the sign reversed for a short.
The model holds funding rate and funding notional constant. A negative total represents a modelled net receipt after these costs, not a profit forecast: price profit or loss, spread, slippage, liquidation, network charges and other costs are excluded.
A $1,000 taker example
Opening and closing $1,000 as a taker costs $1 on each fill, or $2 total. A long position held for three intervals at +0.01% funding adds approximately $0.30. Total cost before a rebate is $2.30.
At an eligible 25% volume rebate, the theoretical rebate on the $2 execution fees is $0.50. That would make the estimated cost $1.80 after payment. Funding is excluded from the rebate calculation.
A volume rebate is paid later
The volume ladder uses trailing 30-day perpetual volume: Starter below $250,000, Trader from $250,000, Pro from $1 million and Legend from $5 million. The respective weekly rebate percentages are 0%, 10%, 20% and 25%.
The fee is charged at execution. Rebate eligibility, minimum payout, weekly aggregation and rounding determine the eventual payment. This calculator does not check your account or include promotional rebates. A pending rebate is not money received. Check Fees & Levels in TRUE.
