Funding Fee Calculator

Funding is the silent cost of holding perps. Project what a position pays (or earns) per interval, per day, and annualized — and see the cumulative cost over your full holding period.

Frequently asked questions

Who pays funding — longs or shorts?

Positive funding rate: longs pay shorts. Negative rate: shorts pay longs. The payment equals position notional × rate, settled every interval (1h on Hyperliquid and Lighter, 8h on most CEXs).

Is 0.01% funding per 8 hours a lot?

It annualizes to roughly 11% per year — usually more than your round-trip trading fees on any position held longer than a day or two. Hot markets can run 5–10x higher.

How do I compare funding across exchanges with different intervals?

Always compare annualized: rate × intervals per day × 365. A +0.002%/1h rate and +0.016%/8h rate look different but cost the same per year. Our live funding page normalizes every venue this way.

Can I earn funding instead of paying it?

Yes — hold the side being paid (e.g., short during positive funding), or run a delta-neutral structure that collects the rate while hedging price risk. Rates flip with sentiment, so it's an income stream with real risks.
