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.

关于资金费率计算器

本工具用于估算持有永续合约仓位时需支付或收取的资金费用。每8小时资金费 = 仓位名义价值 × 资金费率，总资金费 = 该数值 × 结算次数（持仓小时数 ÷ 8）。费率为正时多头支付空头，费率为负时多头收取。可将资金费用纳入波段交易或套息交易的成本核算中。

常见问题

资金费用如何计算？

每期资金费 = 持仓名义价值 × 资金费率。总资金费 = 每期资金费 × 期数，期数 = 持仓小时数 ÷ 8（标准8小时周期）。该工具还显示占名义价值的百分比。

做多时我是支付还是收取资金费？

当资金费率为正时，多头向空头支付，因此多头持仓被收取费用。当费率为负时，空头向多头支付，因此多头反而收取资金费。费率的正负决定了谁来支付。

永续合约的资金费多久收取一次？

Binance和Bybit等大多数交易所每8小时结算一次资金费，每天三次。资金费仅适用于在结算时间点持有的仓位，因此在此之前平仓意味着该期不支付也不收取资金费。
