What is working capital?

Working capital (also called net current assets) is the difference between current assets (what the company has or will receive over the next 12 months) and current liabilities (what the company must pay over the next 12 months).

It is the financial "cushion" that protects a company from treasury crises. Positive working capital means the company can meet its short-term obligations with its short-term assets, without needing emergency financing.

FormulaWorking Capital = Current Assets − Current Liabilities

Current Liquidity Ratio = Current Assets ÷ Current Liabilities

The current liquidity ratio turns this figure into a metric comparable across companies. A ratio of 1.5x means the company has €1.50 of current assets for every €1.00 of current liabilities.

The 3 liquidity ratios you should know

Financial analysts use three progressively stricter ratios to assess a company's liquidity:

RatioFormulaHealthy benchmarkWhat it excludes
Current ratioCA ÷ CL≥ 1.5x
Quick ratio(CA − Inventory) ÷ CL≥ 1.0xInventory (less liquid)
Cash ratioCash ÷ CL≥ 0.2xEverything except cash and equivalents

The quick ratio is especially useful for companies with a lot of stock, because inventory can take weeks or months to convert into cash and should not be counted as immediate liquidity.

When negative working capital can be normal

Negative working capital is generally a warning sign, but there are important exceptions. Companies with upfront-payment business models (supermarkets, online retail, restaurants) get paid by the customer before paying the supplier.

In these cases, current liabilities include supplier debt that is not yet due, but the company already has the cash on hand (from its customers). The ratio looks weak, but the cash cycle is positive.

Rule of thumb: analyse working capital together with the cash conversion cycle (CCC = DSO + DIO − DPO). A negative CCC means the business model generates liquidity on its own, and negative working capital can be healthy in that context.

Warning signs on the balance sheet

These four balance-sheet patterns are often overlooked by SMEs, but they signal serious liquidity problems:

Liquidity ratio below 1.0x

Current liabilities higher than current assets. The company does not have enough assets to cover its short-term obligations. Solution: factoring to turn invoices into immediate cash.

Very high DSO with low DPO

You get paid late but pay early, the worst-case scenario for treasury. Every month that passes increases the working-capital requirement. Optimise your DSO with invoice advances.

Excess stock in current assets

If most of your current assets are idle stock, real liquidity is far lower than the ratio suggests. Review your inventory policy and compare the current ratio against the quick ratio.

Long-term debt maturing in the short term

Bank loans maturing within the next 12 months drastically increase current liabilities. Renegotiate terms or refinance before treasury pressure sets in.

Frequently asked questions

What is working capital?
Working capital is the difference between current assets and current liabilities. It measures a company's short-term liquidity. WC = Current Assets − Current Liabilities. Positive working capital means the company has enough resources to meet its short-term commitments.
Is negative working capital always bad?
Not necessarily. Companies with strong bargaining power (large retail, supermarkets) typically operate with negative working capital because they get paid upfront and pay on terms. However, for most Portuguese SMEs, negative working capital is a liquidity-risk signal that should be monitored.
How do you improve working capital?
The main strategies are: reduce DSO through factoring (get paid faster), increase DPO via confirming (pay later), and manage stock efficiently. Factoring can turn receivables into immediate cash, directly improving current assets.

Improve your working capital with factoring

Turn invoices into cash in 24-48 hours. Factoring is the most direct way to improve working capital without resorting to traditional bank credit.
