In my experience, net working capital (NWC) is the fastest read on whether a business can keep running day to day, and the formula is simple: current assets minus current liabilities. A positive number means you can cover what's due over the next year with room to spare; a negative one can signal a cash crunch. Below, I'll break down the formula and its components, walk through an example, and show you how I read and improve NWC, including when it makes sense to bridge a gap with financing.
Net Working Capital Formula and Components
The net working capital formula is:
Net working capital =
current assets − current liabilities
Both figures come straight off your balance sheet, one of your core financial statements. Current assets are the liquid assets you can turn into cash within a year, and current liabilities are the short-term obligations due in that same window:
Current assets
Cash and cash equivalents, marketable securities, accounts receivable, inventory (raw materials and finished goods), and prepaid expenses
Current liabilities
Accounts payable, accrued expenses, short-term debts, and other short-term financial obligations due within a year
Analysts sometimes use an operating version that strips out cash and short-term investments on the asset side and debt on the liability side, leaving operating current assets minus operating current liabilities. That variant isolates the working capital tied to running the business, which is why it shows up in valuation (often alongside EBITDA), financial modeling, and financial analysis.
How To Calculate Net Working Capital: An Example
Say a business heads into 2026 with $250,000 in current assets and $150,000 in current liabilities. Its net working capital is $100,000, and its current ratio (current assets divided by current liabilities) is 1.67. That ratio is a quick companion metric: anything above 1.0 means positive NWC, and 1.2 to 2.0 is generally considered a healthy range. Push much past that, and the ratio can cut the other way, since it may mean cash, inventory, or receivables are sitting idle instead of going back into the business.
NWC is a balance-sheet financial metric, so it reflects what you own and owe right now rather than your net income for the year, which lives on the income statement. Tracking the change in net working capital from period to period also matters because a rising NWC ties up cash while a falling one frees it, which flows through to your free cash flow and cash flow statement.
Positive vs. Negative Net Working Capital
Positive net working capital is a sign of financial stability and liquidity: You hold more than enough short-term resources to fund operations and take on growth opportunities. Negative working capital means your short-term liabilities outweigh your current assets, which can point to a cash crunch, though fast-turning businesses like some retailers run lean on purpose.
The distinction matters beyond your own books. Lenders read NWC as a signal of creditworthiness and financial stability, so a persistently negative number can make external financing like short-term loans and lines of credit harder to secure right when you need it most.
How Much Net Working Capital Does Your Business Need?
The right amount depends on your model and how fast cash moves through it. A common rule of thumb is that a business should be able to cover roughly three months of expenses from its current assets. Operational efficiency and industry norms shift the target:
Retailers: Collect cash quickly and pay suppliers on terms, so they operate on lower NWC.
Manufacturers: Carry raw materials and finished goods through long production cycles, so they need more NWC and sharper inventory management.
Service businesses: Hold little inventory, so their needs fall between the two and hinge on how fast clients pay.
Ways To Improve Your Net Working Capital
Most improvements come from speeding up cash in and slowing down cash out, the core of good cash flow management:
Accelerate receivables: Invoice promptly, tighten payment terms, and follow up on overdue accounts receivable.
Manage inventory: Keep enough stock to sell without tying up cash in slow-moving raw materials or finished goods.
Negotiate payables: Ask vendors for longer terms on accounts payable so cash stays in your account longer.
Those take time, though, and a seasonal dip or a big order can open a gap faster than you can close it. That's when external financing earns its place: A working capital loan or a business line of credit covers short-term obligations without draining your reserves, and invoice factoring turns unpaid receivables into cash. For a fast, one-time need, a short-term loan can bridge the gap.

Net Working Capital FAQ
These are answers to a few of the questions I often get from business owners about net working capital.
What Is Net Working Capital?
Net working capital is the difference between a company's current assets and its current liabilities. It measures short-term liquidity, or whether a business has enough resources on hand to cover the obligations coming due within the next year.
How Do You Calculate Net Working Capital?
Subtract current liabilities from current assets. Total your cash, accounts receivable, inventory, and other current assets, total your accounts payable, accrued expenses, and short-term debt, and take the difference. The calculator above does it for you.
What Is the Difference Between Working Capital and Net Working Capital?
In everyday use, they're the same figure: current assets minus current liabilities. When finance professionals draw a line, "net working capital" often refers to the operating version that excludes cash and debt, while "working capital" refers to the straight balance-sheet total.
