What is Net Working Capital (NWC)?
Net Working Capital (NWC) measures a company’s short-term liquidity and operational efficiency by comparing its current assets to its current liabilities.
It indicates the firm’s ability to meet short‑term obligations, manage day‑to‑day operations, and sustain smooth cash flow. Positive NWC suggests financial stability, while negative NWC may signal liquidity stress.
Definition
Net Working Capital (NWC) is the difference between a company’s current assets and current liabilities, used to assess short‑term financial health.
Key takeaways
- Liquidity indicator: Shows a business’s ability to cover short-term obligations.
- Operational efficiency: Reflects how effectively working capital components are managed.
- Positive vs. negative NWC: Positive means assets exceed liabilities; negative signals potential cash flow issues.
- Critical for cash flow: Influences purchasing, inventory, and credit policies.
- Widely used: Essential in financial analysis, lending, and valuation.
How NWC is calculated
Formula:
NWC = Current Assets – Current Liabilities
Common components:
- Current assets: Cash, receivables, inventory.
- Current liabilities: Payables, short-term debt, accrued expenses.
Example:
If current assets = $500,000 and current liabilities = $350,000:
NWC = $150,000
Why NWC matters
For businesses:
- Ensures smooth day‑to‑day operations.
- Supports inventory purchases and receivables management.
- Helps avoid liquidity shortages.
For investors and lenders:
- Indicates financial stability and operational discipline.
- Used in credit evaluations.
- Influences valuation models and working-capital adjustments.
Factors affecting NWC
- Sales growth or decline
- Inventory turnover
- Payment terms with suppliers
- Customer credit policies
- Seasonality
- Cash management practices
NWC vs. working capital ratio
| Metric | Description |
|---|---|
| NWC | Dollar amount of liquidity (assets minus liabilities) |
| Current Ratio | Liquidity ratio (current assets ÷ current liabilities) |
Both measure liquidity, but NWC shows absolute dollars rather than a ratio.
Strategies to improve NWC

- Reduce excess inventory
- Improve forecasting and cash management
- Refinance short-term debt
