Funding settles roughly every 8 hours (≈ 3 periods/day) — held over time it compounds. Educational tool only, not financial advice. Verify the rate and schedule with your platform.

How it's calculated
Funding per period = position size × funding rate. With a positive rate a long pays and a short receives (and vice-versa). Total = per-period × periods held — funding settles roughly every 8 hours.
Worked example
Hold a $10,000 long while the funding rate is +0.01% per 8-hour period and you pay $10,000 × 0.0001 = $1 each period. Over three days (nine periods) that's about $9 — paid to the shorts, not to the exchange. If the rate were negative, you'd receive it instead.
FAQ
- Is funding a fee the exchange keeps?
- No. Funding is exchanged between traders — longs pay shorts or shorts pay longs, depending on the sign of the rate. The exchange doesn't collect it; it's the mechanism that keeps a perpetual's price tied to spot.
- How often is funding charged?
- On most venues, every 8 hours — three times a day. The cost compounds across multi-day holds, which is why it matters for anything longer than a quick trade.
