See what funding costs — or pays — you on a perpetual position over time, and what that rate works out to annualized.

DirectionLong
Funding is paid directly between traders every interval (commonly 8h), not to the exchange. Rates change each interval, so this assumes a constant rate for the whole hold — treat it as an estimate.

FAQ
Straight answers, no hedging.
What is a funding rate?
On perpetual futures, the funding rate is a periodic payment exchanged directly between longs and shorts (not a fee to the exchange) that keeps the perpetual price tethered to spot. When the rate is positive, longs pay shorts; when negative, shorts pay longs. It is usually charged every 8 hours.
How is the funding fee calculated?
Funding per interval is your position's notional size multiplied by the funding rate. Multiply by the number of intervals you hold for the total. Whether you pay or receive depends on your direction and the rate's sign.
How do I annualize a funding rate?
Multiply the per-interval rate by the number of intervals in a year. At an 8-hour interval that is three per day, so APR ≈ rate × 3 × 365. Small per-interval rates compound into large annualized numbers — which is why funding matters for positions held a while.
Is this exact for Binance, Bybit, OKX, or Bitget?
No calculator outside the exchange can be exact. Liquidation and margin depend on the venue's maintenance-margin tiers, margin mode, funding, fees, and any position changes. These figures are close estimates for isolated USDT linear perpetuals — always confirm on your exchange before trading.
Does this calculator give trading advice?
No. Every output is general market and risk education — not financial advice, investment advice, or a recommendation to trade. What you do with the numbers is your decision and your responsibility.
