The calculation
Trading fee = executed notional × fee rate. For eligible fee sharing, estimated net fee = trading fee × 80%. A $10,000 trade at an illustrative 0.05% costs $5 before sharing and $4 after sharing. This is a worked example, not a published current fee tier.
Maker, taker and volume
An order that adds liquidity can receive a maker rate; an immediately matching order can receive a taker rate. A limit order is not automatically a maker order. Use the rate actually shown for your product and account tier, and add the volume from both legs of a round trip.
Costs outside this calculator
Spread and slippage affect execution prices. Perpetual positions may pay or receive funding. Deposits and withdrawals can involve network or provider charges. Fee sharing is not a discount on these costs and does not apply to Equity Perps.
