What Is the Calculation Formula for the Funding Payment?

The funding payment is calculated by multiplying the position's notional value by the funding rate. The notional value is the size of the position multiplied by the Mark Price.

The funding rate itself is often calculated using a formula involving the difference between the Mark Price and the Index Price, adjusted by an interest rate component and a time decay factor. This final payment is exchanged directly between traders.
