## Definition
|
||||
现金流预测是通过历史模式分析和季节性因子,对企业未来若干期(通常为 12 期滚动)的现金收支进行量化预测的过程,旨在维持流动性并优化资金使用效率。
|
||||
|
||||
## Core Components
|
||||
- **历史模式分析**:按月聚合 receipts(收款)、payments(付款)、net_cash_flow(净现金流)的均值和标准差
|
||||
- **季节性因子**:针对不同月份应用季节性调整系数,反映周期性波动
|
||||
- **增长因子**:根据业务增长趋势调整预测基准
|
||||
- **置信区间**:通常设置 ±15% 的置信区间(如 net_cash_flow × 0.85 / 1.15)
|
||||
|
||||
## Key Metrics
|
||||
- **累积现金**(cumulative_cash):当前现金余额 + 预测期净现金流之和
|
||||
- **低现金预警**:累积现金 < $50,000 时触发,行动建议为加速收款或延迟付款
|
||||
- **高现金机会**:累积现金 > $200,000 时触发,建议考虑短期投资或预付费用
|
||||
|
||||
## Payment Timing Optimization
|
||||
根据以下公式计算支付优先级分数:
|
||||
```
|
||||
priority_score = early_pay_discount × amount × 365 / payment_terms
|
||||
```
|
||||
优先处理高折扣机会,同时维持现金流健康。
|
||||
|
||||
## Implementation
|
||||
参见 [[support-finance-tracker]] 中 `CashFlowManager` Python 类的实现。
