Was ist Working Capital?

Working Capital ist eine wichtige Finanzkennzahl, die die kurzfristige Liquiditat eines Unternehmens misst.

Formel fur Net Working Capital (NWC)

Die Standardformel lautet:

NWC = Umlaufvermogen - kurzfristige Verbindlichkeiten

Warum ist Working Capital wichtig?

Ein positives Working Capital bedeutet, dass ein Unternehmen seine kurzfristigen Verbindlichkeiten mit seinem Umlaufvermogen decken kann. Ein negatives WC kann auf Liquiditatsprobleme hinweisen.

Working Capital, Explained in Plain English

Working capital (also called net working capital, or NWC) measures a company's short-term liquidity – its ability to cover near-term obligations with the assets it can convert to cash quickly. It's one of the first numbers finance professionals check when assessing whether a business can fund its day-to-day operations without external financing.

Net Working Capital Formula

The standard formula is:

NWC = Current Assets − Current Liabilities

Current assets typically include cash, accounts receivable, and inventory – items expected to convert to cash within 12 months. Current liabilities include accounts payable, short-term debt, and accrued expenses – obligations due within the same period.

Some analysts use a narrower measure, operating working capital, which excludes cash and short-term debt since these are financing items rather than operating items:

Operating NWC = (Accounts Receivable + Inventory) − Accounts Payable

Why Working Capital Matters

Positive working capital means a company can cover its short-term liabilities with its current assets – a sign of healthy liquidity. Negative working capital can signal a looming cash crunch, though some business models (e.g. subscription businesses or grocery retail, where customers pay upfront and suppliers are paid later) run structurally negative working capital by design without it being a red flag.

Working Capital in Financial Modeling and Valuation

In a DCF, the change in net working capital is subtracted from after-tax EBIT plus D&A to arrive at unlevered free cash flow. A rising NWC (a company tying up more cash in receivables and inventory) reduces free cash flow; a falling NWC releases cash. This is a common interview question: be ready to explain why a rising NWC is a cash outflow even though it never appears on the income statement.

How to Improve Working Capital

  • Inventory management: reduce excess stock and improve inventory turnover without risking stockouts
  • Payment terms: negotiate longer payment terms with suppliers and shorter terms with customers
  • Receivables management: tighten collections to reduce days sales outstanding (DSO)

Frequently Asked Questions About Working Capital

What is working capital?

Working capital, or net working capital (NWC), is the difference between a company's current assets and current liabilities. It measures how much cash a business has tied up in (or freed up from) its short-term operating cycle, and is a core indicator of short-term liquidity.

What is a good working capital ratio?

The working capital ratio (also called the current ratio) is current assets divided by current liabilities. A ratio between 1.2 and 2.0 is generally considered healthy: high enough to comfortably cover short-term obligations, but not so high that the company is holding excess idle assets instead of reinvesting or returning cash.

What's the difference between working capital and net working capital?

The two terms are usually used interchangeably. When a distinction is drawn, "working capital" sometimes refers to gross working capital (total current assets alone), while "net working capital" specifically means current assets minus current liabilities – the definition used throughout this article.

Is working capital the same thing as cash?

No, and this is one of the most common points of confusion for candidates new to the concept. Cash is a single line item on the balance sheet, while net working capital is a calculated figure spanning multiple current assets and current liabilities. A company can have very little cash on hand but strongly positive net working capital if it holds substantial receivables and inventory, and conversely a company can be cash-rich while still showing negative net working capital if its current liabilities are unusually large relative to its non-cash current assets. This is exactly why analysts look at both metrics side by side rather than treating either one alone as a complete picture of short-term financial health.

Does more working capital always mean a healthier company?

Not necessarily. While negative working capital can be a red flag, an unusually high working capital ratio isn't automatically a positive sign either — it can indicate the company is sitting on excess, unproductive inventory, or is too slow at collecting from its customers relative to peers. Private equity buyers in particular often view a working-capital-heavy target as an opportunity: tightening receivables collection or renegotiating supplier terms after acquisition can free up meaningful cash without touching the underlying operating business at all, which is one of several operational levers that make a target attractive in the first place.

The Cash Conversion Cycle: Working Capital in Motion

Net working capital is a snapshot at a single point in time, but the underlying dynamics that drive it are best understood through the cash conversion cycle (CCC) — the number of days between when a company pays cash out for inventory and when it collects cash back in from customers. The cycle has three components: Days Sales Outstanding (DSO), which measures how long it takes to collect from customers after a sale; Days Inventory Outstanding (DIO), which measures how long inventory sits before being sold; and Days Payable Outstanding (DPO), which measures how long the company takes to pay its own suppliers. A shorter cash conversion cycle means cash is tied up for less time, which is why companies with strong negotiating leverage over both customers and suppliers — large retailers, for instance — often manage to run a negative cash conversion cycle, collecting from customers before they even have to pay their own suppliers. The full mechanics of calculating and interpreting DSO, DIO, and DPO together are covered in Working Capital Deep Dive.

How Working Capital Feeds Into Free Cash Flow

Working capital doesn't just sit on the balance sheet as an abstract liquidity measure — it directly determines how much cash a business actually generates in a given period, which is why it's a required input into any free cash flow calculation. Starting from EBIT, a financial analyst adds back D&A, subtracts cash taxes, subtracts CapEx, and then subtracts the increase in net working capital (or adds back a decrease) to arrive at unlevered free cash flow. A fast-growing company can show strong accounting profit while actually burning cash, precisely because rapid revenue growth often requires building up receivables and inventory faster than payables grow to offset them — a dynamic that trips up candidates who assume growing profit always means growing cash. The full bridge from net income to free cash flow, including exactly where the working capital adjustment fits, is walked through in Free Cash Flow from the Statements, and the broader distinction between unlevered and levered free cash flow is explained in what free cash flow actually measures.

Working Capital in M&A: The Peg That Protects Both Sides

Working capital takes on a very different role once a company is being bought or sold. In nearly every M&A agreement, the buyer and seller agree on a working capital "peg" — a target level of working capital the seller must leave in the business at closing, based on a historical average. If actual working capital at closing comes in below the peg, the purchase price is reduced dollar-for-dollar; if it comes in above the peg, the seller typically receives an increase. This mechanism exists because a seller has an obvious incentive to strip cash out of the business and delay paying suppliers right before a sale closes, which would leave the buyer with a business that needs an immediate cash injection just to keep operating normally — the working capital peg neutralizes that incentive for both sides. The full negotiation dynamics and a worked example of how a peg dispute gets resolved are covered in What Is a Working Capital Peg in M&A?, with the interview-focused framework for answering peg-related questions available in the companion working capital peg guide.

Answering Working Capital Questions in a Finance Interview

Working capital questions in interviews rarely stop at the definition. Interviewers typically want to see a candidate walk through DSO, DIO, and DPO with actual numbers, explain why an increase in net working capital is a use of cash even though it never touches the income statement, and connect the concept to a broader valuation or M&A context rather than treating it as an isolated balance sheet metric. A step-by-step framework for structuring that kind of answer, including a full worked calculation, is covered in how to calculate working capital in an interview. Candidates who can move fluidly between the balance sheet definition, the cash flow statement impact, and the M&A negotiation angle demonstrate exactly the kind of layered understanding that separates a strong answer from a merely textbook one.

Industry Patterns: Why Working Capital Needs Vary So Much

Working capital intensity differs enormously by business model, and recognizing this pattern is often what separates a candidate who can recite the formula from one who understands what it means. Capital-light software and subscription businesses often collect payment upfront (deferred revenue is technically a current liability, but the cash is already in hand) and carry little to no physical inventory, which pushes their working capital needs toward zero or even negative. Manufacturers and industrial companies sit at the other extreme: they have to buy raw materials, hold them as inventory, convert them into finished goods, and often extend 30-to-90-day payment terms to customers, all of which ties up substantial cash before a single dollar of profit is collected. Grocery and big-box retailers are a notable middle case that behaves like the software model: they collect cash from customers immediately at checkout but often negotiate 60- or 90-day payment terms with suppliers, which lets them effectively run their businesses on their suppliers' money. This pattern matters directly for deal-making — a private equity buyer evaluating an acquisition target will look closely at how working-capital-intensive the business is, because a company with heavy structural working capital needs requires more cash just to fund its own growth, which directly affects how much leverage the deal can support and what the buyer should actually pay.

A Worked Example: Calculating the Change in NWC

Suppose a company's current assets (accounts receivable plus inventory) were $80m at the start of the year and grew to $95m by year-end, while current liabilities (accounts payable) grew from $50m to $54m over the same period.

Net Working Capital at the start of the year = $80m − $50m = $30.0m

Net Working Capital at the end of the year = $95m − $54m = $41.0m

Change in Net Working Capital = $41.0m − $30.0m = $11.0m increase

Because this $11.0m represents cash the company had to tie up in additional receivables and inventory (net of the extra payables it was able to delay paying), this increase in net working capital is subtracted from free cash flow for the period — even though the underlying revenue growth that drove it would show up as a gain on the income statement. This is exactly the kind of scenario interviewers use to test whether a candidate understands that profit and cash flow are not the same thing, and that a growing, profitable company can still be a heavy consumer of cash if its working capital needs are growing even faster than its earnings.
