营运资金是衡量公司短期财务健康状况和运营效率的基本商业财务指标。了解如何计算和解释营运资本有助于投资者、债权人和企业管理者评估流动性,并就企业生存能力和运营管理做出明智的决策。
什么是营运资金?
营运资金代表流动资产与流动负债之间的差额。它衡量可用于公司日常运营和短期债务的资金数额。
Working Capital = Current Assets - Current Liabilities
了解组件
流动资产(12个月内可转换为现金):
- 现金及现金等价物
- 应收账款
- 存货
- 短期投资
- 预付费用
流动负债(12 个月内到期):
- 应付账款
- 短期债务
- 应计费用
- 长期债务的当前部分
- 应付工资
基本计算示例
示例 1:健康的营运资金
Current Assets:
Cash: $50,000
Accounts receivable: $75,000
Inventory: $100,000
Total: $225,000
Current Liabilities:
Accounts payable: $50,000
Short-term debt: $30,000
Accrued wages: $20,000
Total: $100,000
Working Capital = $225,000 - $100,000 = $125,000
示例 2:负营运资金
Current Assets: $150,000
Current Liabilities: $180,000
Working Capital = $150,000 - $180,000 = -$30,000
营运资金组成表
| 资产/负债 | 数量 |
|---|---|
| 流动资产 | |
| 现金 | $50,000 |
| 应收账款 | $75,000 |
| 存货 | $100,000 |
| 预付费用 | $10,000 |
| 流动资产总额 | $235,000 |
| 流动负债 | |
| 应付账款 | $60,000 |
| 短期债务 | $40,000 |
| 应计工资 | $25,000 |
| 流动负债总额 | $125,000 |
| 营运资金 | $110,000 |
营运资金比率(流动比率)
流动比率显示每一美元的流动负债对应多少美元的流动资产:
Current Ratio = Current Assets ÷ Current Liabilities
例子:
Current Assets: $200,000
Current Liabilities: $100,000
Current Ratio: $200,000 ÷ $100,000 = 2.0
(For every $1 of liabilities, there are $2 of assets)
理想的电流比率范围
| 比率 | 解释 |
|---|---|
| < 1.0 | 流动资产不足以偿还负债 |
| 1.0 - 1.5 | 流动性可能紧张 |
| 1.5 - 3.0 | 一般健康范围 |
| > 3.0 | 可能表明资产未得到充分利用 |
速动比率(酸性测试)
速动比率比较保守,不包括库存:
Quick Ratio = (Current Assets - Inventory) ÷ Current Liabilities
例子:
Current Assets: $200,000
Inventory: $75,000
Current Liabilities: $100,000
Quick Ratio = ($200,000 - $75,000) ÷ $100,000 = 1.25
销售应收天数 (DSO)
衡量公司收回应收账款的速度:
DSO = (Accounts Receivable ÷ Annual Revenue) × 365
例子:
Accounts Receivable: $100,000
Annual Revenue: $1,000,000
DSO = ($100,000 ÷ $1,000,000) × 365 = 36.5 days
(Takes 36-37 days to collect payment on average)
库存周转率
衡量库存销售速度:
Inventory Turnover = Cost of Goods Sold ÷ Average Inventory
Days Inventory Outstanding = 365 ÷ Inventory Turnover
例子:
COGS: $500,000
Average Inventory: $100,000
Inventory Turnover = $500,000 ÷ $100,000 = 5x per year
Days held = 365 ÷ 5 = 73 days
营运资金管理周期
营运资金周期显示了资金被占用的时间:
Cash Conversion Cycle = DSO + Days Inventory Outstanding - Days Payable Outstanding
例子:
Days to collect from customers: 40 days
Days inventory is held: 75 days
Days to pay suppliers: 30 days
Cash Conversion Cycle = 40 + 75 - 30 = 85 days
按行业划分的营运资金
| 行业 | 典型的卫生间 |
|---|---|
| 零售 | 负向低 |
| 制造业 | 中到高 |
| 技术 | 高(研发密集型) |
| 公用事业 | 缓和 |
| 金融 | 多变的 |
营运资金负面分析
根据行业的不同,负营运资本可能令人担忧或正常:
关于负 WC:
- 公司难以支付债务
- 可能需要外部融资
- 破产风险
正常负WC(某些行业):
- 零售商先收货再付款给供应商
- 示例:沃尔玛的 WC 为负,但现金流强劲
营运资金改善策略
| 战略 | 影响 | 例子 |
|---|---|---|
| 提高收集速度 | 减少DSO | 更快地通过电子邮件发送发票 |
| 提高库存周转率 | 减少DIO | 减少滞销库存 |
| 延长付款期限 | 增加DPO | 协商 45 天条款 |
| 降低库存水平 | 降低资产需求 | 及时库存 |
| 加速收入增长 | 更高的现金流入 | 促销折扣 |
真实业务示例
示例:制造公司
Month 1 WC: $150,000 (healthy)
Month 2 WC: $120,000 (declining)
Month 3 WC: $90,000 (concerning trend)
Actions needed:
- Accelerate customer collections
- Reduce inventory levels
- Negotiate extended payment terms with suppliers
营运资金融资
当营运资金不足时,公司使用:
- 信用额度:短期借款便利
- 保理:以折扣价出售应收账款以获得即时现金
- 贸易信贷:协商延长付款条件
- 存货融资:以存货为抵押借款
目标是保持充足的营运资金以支持运营,同时最大限度地提高效率。
