Funding Calculation

More information about the funding rate is available in the Perpetuals Guide.

Interest BaseInterest QuotePremium

I = Interest Rate, B = Interest Base, Q = Interest Quote, T = Funding Times Per Day
P = Premium Rate, F = Funding Rate
The Funding Rate is the rate exchanged between users.
The Premium Rate is used to calculate it, adjusted by the Interest Rate by up to 0.05%.


I = (Q - B) / T
F = P + Clamp(I - P, -0.05%, 0.05%)


I = 0.0100%
I = (0.06% - 0.03%) / 3
F = 0.0100%
F = 0.0100% + Clamp(0.0100% - 0.0100%, -0.05%, 0.05%)
