费率很小，
不代表成本很小。
从零理解永续合约资金费率：正负费率的支付方向、按名义价值计算的方法、结算周期、杠杆影响、常见误区与持仓前检查清单。
合约没有平仓、价格也没动，为什么仍可能扣钱？
只要满足平台在结算时刻的持仓条件，就可能支付或收到资金费，它不取决于这笔仓位是否已经盈利。不要把资金费、借贷利息和开平仓手续费混成一笔。核对账单的费用名称、合约、方向和结算时间，再使用情景计算器。
持仓小时数本身不能确定结算次数：持仓1小时可能跨过结算，持仓7小时也可能未跨过。以具体结算时间戳计数；不同期费率变化时应逐期核算，固定费率工具只是估算。

资金费不是平台利息
永续合约没有到期交割日。资金费机制通过多空双方定期互相支付，促使永续价格靠近指数价格。通常费率为正时多头付给空头，为负时空头付给多头；平台一般负责计算和划转，具体组成、上下限与结算规则以当前合约说明为准。
不要只看保证金
单期资金费 = 仓位名义价值 × 资金费率
1 万美元仓位、当期费率 0.01%，单期金额约为 1 美元。正负号和持仓方向决定你支付还是收到。
Funding fee calculator: holding time and settlement
A flat market price does not prevent funding payments. For a linear contract, one hypothetical settlement costs notional × funding rate; 10,000 × 0.01% = 1. With three settlements and an unchanged rate and notional, the total is 3. Long/short direction and the rate sign determine payment or receipt under the venue rules. Count actual settlement timestamps while the position is eligible; one hour can cross a settlement while seven hours might not. Interval-hours in the tool are not actual holding duration. Rates, intervals and notional can change. Excludes trading P&L, trade fees and liquidation.

多期估算 = 单期金额 × 预计结算次数
若费率和仓位都不变，连续 3 期约为 3 美元。但真实费率、标记价格和仓位价值可能每期变化。

相对保证金影响 = 累计资金费 ÷ 保证金
同一笔 3 美元成本，相对 1,000 美元保证金为 0.3%。杠杆越高，名义仓位相对本金越大，持仓成本与强平风险越敏感。

8 小时常见，但不是统一规则
- 部分合约采用 1、2、4 或 8 小时等周期，平台也可能根据市场状况调整
- 预计费率不是最终费率；临近结算仍需查看合约页面的实时数值
- 资金费通常只在结算时刻对仍持仓的账户发生，但应以该平台规则为准
- 资金费、开平仓手续费、滑点和强平损失是不同项目，必须分别计算
- 平台可能设置费率上下限或特殊计算方式，不能直接套用另一平台的数据
五项持仓检查
- 确认合约、持仓方向、名义价值和保证金币种
- 查看当前预计费率、支付方向、结算倒计时与费率上下限
- 计算单期与多期金额，并换算为保证金占比
- 检查标记价格、维持保证金率和强平价格，预留波动缓冲
- 保存结算账单，复核实际资金费，不把“收到资金费”误当作无风险收益
把小数变成真实金额

结算前必须弄清的问题
资金费率为正时谁付钱？
通常由多头向空头支付；为负时通常由空头向多头支付。结算前应以平台合约页面显示的方向和最终费率为准。
所有合约都是每 8 小时结算吗？
不是。8 小时很常见，但平台可按合约采用 1、2、4 或 8 小时等周期，也可能调整周期。请查看当前合约规则和结算倒计时。
平仓后还会收取当期资金费吗？
资金费通常只在结算时刻向仍持仓的账户收付，但不同平台可能有不同处理方式。不要只凭经验卡点，应以实时规则和账单为准。
负资金费率意味着价格一定上涨吗？
不意味着。资金费率只能反映永续市场的一部分多空供需，不能单独预测方向，也不能覆盖基差、波动率、流动性或强平风险。
