Net Working Capital
What is net working capital?
Net working capital is current assets minus current liabilities. It shows whether a firm has enough short-term resources to cover its short-term obligations. For service firms, it is mostly cash and receivables on one side and payables and accrued costs on the other.

How to calculate and read it
- Add cash, receivables, and other current assets
- Subtract payables, accrued expenses, and other current liabilities
- Track the trend monthly, since a falling balance can signal slow collections or growing obligations
A worked example
The figures below are illustrative. A firm has $90,000 in cash and receivables and $60,000 in payables and accrued costs, so its net working capital is $30,000. If receivables slow down while payroll stays the same, the balance shrinks even though revenue looks healthy.
Common mistakes
- Counting receivables that are unlikely to be collected
- Leaving accrued payroll and taxes out of liabilities
- Comparing balances across periods without allowing for seasonality
Why it matters for service firms
Net working capital is a practical cash-health measure. Lenders and buyers look at it, and in a sale a working capital adjustment can change the price. Reading it with days sales outstanding shows why it is moving.
Frequently asked questions
What is the difference between working capital and net working capital?
Working capital often refers to the current assets a firm uses to operate, while net working capital is the number left after subtracting current liabilities. In practice the terms are often used interchangeably.
Is more net working capital always better?
Not necessarily. A large balance can mean cash is sitting idle or receivables are building up. Compare it with revenue and collections to judge whether it is healthy or inefficient.
