Core Components of Perpetual Futures Fee Calculation

1. Trading Fees

Maker Fees

A maker adds liquidity by placing a limit order that does not immediately execute. Maker fees are usually lower and sometimes even negative (rebates).

Taker Fees

A taker removes liquidity by executing against an existing order in the book. Taker fees are higher and apply to market orders or aggressive limit orders.

Formula for Trading Fees:

Trading Fee = Trade Size × Fee Rate

Example:

  • Trade Size = $100,000
  • Taker Fee Rate = 0.05%
  • Fee = \(100,000 × 0.0005 = **\)50**

2. Funding Fees

Funding rates ensure that perpetual futures prices stay close to the spot price. Depending on market conditions, funding can be positive or negative.

Formula for Funding Fee:
