Crypto Perpetual Funding Rate Impact Calculator
Calculate 8-hour perpetual funding costs paid or received across long and short crypto futures positions on Binance, Bybit, and OKX.
Understanding Perpetual Swap Funding Rates
Unlike traditional futures contracts that expire quarterly, perpetual futures contracts have no expiration date. To keep perpetual contract prices tethered to underlying spot market prices, crypto exchanges use a Funding Rate mechanism. Payments are exchanged directly between long and short traders every 8 hours.
Positive vs Negative Funding Rate Dynamics
When perpetual contract prices trade at a premium to spot prices (bullish sentiment), the funding rate is positive—longs pay shorts. When perpetual prices trade at a discount (bearish sentiment), funding is negative—shorts pay longs. Holding large positions during high funding periods adds significant fee drag.
How to Use This Funding Rate Calculator
Enter position notional value ($), current predicted funding rate % (e.g. +0.01% or +0.05%), trade direction (Long or Short), and expected holding duration in 8-hour intervals. The calculator computes exact funding fee paid or earned per interval and total over time.
Funding Rate Arbitrage (Delta-Neutral Strategies)
Institutional crypto desks exploit extreme positive funding rates by taking a long spot position and an equivalent short perpetual position. This delta-neutral hedge eliminates market price risk while collecting positive funding yield every 8 hours.
