About the Funding Fee Calculator
This tool estimates the funding you will pay or receive holding a perpetual futures position. Funding per 8-hour interval = position notional × funding rate, and total funding = that figure × the number of intervals (holding hours ÷ 8). Long positions pay when the rate is positive and receive when it is negative; use it to factor funding into the cost of a swing or carry trade.
Frequently Asked Questions
How is the funding fee calculated?
Funding per interval = position notional × funding rate. Total funding = funding per interval × number of intervals, where intervals = holding hours ÷ 8 for the standard 8-hour cycle. This tool also shows the total as a percentage of your notional.
Do I pay or receive funding when I am long?
When the funding rate is positive, longs pay shorts, so a long position is charged. When the rate is negative, shorts pay longs, so a long receives funding instead. The sign of the rate decides who pays.
How often is funding charged on perpetual futures?
Most exchanges such as Binance and Bybit settle funding every 8 hours, three times a day. The funding only applies to positions held at the settlement timestamp, so closing before it means you neither pay nor receive that interval.
