// What the wire costs over the hold. Negative rate? Flip the sign — funding flows your way.
> Negative numbers in red mean you're paying. Positive numbers in green mean you're collecting (rare on a single venue — that's why funding arb exists).
Per-interval funding rate annualizes by the number of intervals in a year. The total dollar cost is the rate times your position size times the count of intervals you held through.
payments = floor(hold_hours / interval_hours) cost_per_pay = position * (rate_pct / 100) total_cost = payments * cost_per_pay annualized = rate_pct * (8760 / interval_hours)
Typical perp funding intervals: Hyperliquid + Lighter pay hourly, Paradex pays every 8 hours. The shorter the interval, the faster you compound a positive carry — and the faster you bleed if the spread inverts.
