A positive rate means longs pay shorts if both remain open at the corresponding settlement; a negative rate reverses that cash flow. Funding is calculated on the perpetual leg’s notional value, not its margin. The period forecast can still change before settlement.
The common scale is linear: 8h equivalent = period forecast × 8 ÷ interval hours; nominal annual scale = period forecast × 24 ÷ interval hours × 365. For example, 0.01% per 4 hours is 0.02% per 8 hours and a 21.90% simple annual scale. This does not imply later periods will keep the same rate.
OKX documents fundingRate as the forecast approaching fundingTime, while nextFundingTime is the next estimated settlement; the interval can change dynamically. We checked the official API documentation in September 2026. A contract with an invalid rate, either invalid timestamp, or an API error is excluded rather than shown as zero.
Checks before using the number
- Confirm the latest settlement time on the contract page because the estimated next interval can change.
- Keep a forecast separate from the final settled rate; do not project one reading across several days.
- Calculate funding, trading fees, slippage, margin and liquidation risk separately.
- A large absolute rate describes current funding cash flow; it does not establish that price will reverse.
Estimate an explicit number of settlements with the perpetual funding cash-flow estimator, or compare notional and initial-margin scales with the Annualized Funding Calculator.
