Working capital in Belgium: net working capital vs working capital requirement
Tips
The short answer
Belgian analysis uses two working capital figures. Net working capital is stocks (code 3), receivables within a year (40/41), current investments (50/53), cash (54/58) and asset accruals (490/1), minus debts due within a year (42/48) and liability accruals (492/3): the margin long-term funding leaves for the short term. The working capital requirement (behoefte aan bedrijfskapitaal) is what the operating cycle ties up: stocks, receivables and accruals minus the non-financial short-term debts to suppliers, staff, the tax authorities and customers who paid in advance. Net working capital minus the requirement is the net cash position. A retailer paid at the till can run a negative requirement and be healthy; a wholesaler usually cannot.
The definitions come from the National Bank's analysis of Belgian company accounts (Economic Review, December 2014), the codes from the National Bank's standard models and ratio definitions, all read on 1 October 2026. This is general information, not accounting or financial advice.
Net working capital: the National Bank definition
The National Bank defines net working capital as the difference between the current assets that are constantly renewed by the business and the debts due within one year. In balance sheet codes:
Net working capital = 3 + 40/41 + 50/53 + 54/58 + 490/1 minus 42/48 minus 492/3
Code | Balance sheet line | Net working capital | Working capital requirement |
|---|---|---|---|
3 | Stocks and contracts in progress | Added | Added |
40/41 | Receivables within one year (40 trade, 41 other) | Added | Added |
50/53 | Current investments | Added | Left out |
54/58 | Cash at bank and in hand | Added | Left out |
490/1 | Deferred charges and accrued income | Added | Added |
42, 43 | Long-term debts due within the year; financial debts | Subtracted | Left out |
44 | Trade debts (suppliers, bills payable) | Subtracted | Subtracted |
46 | Advance payments received on orders | Subtracted | Subtracted |
45 | Taxes, remuneration and social security | Subtracted | Subtracted |
47/48 | Other debts | Subtracted | Subtracted |
492/3 | Accrued charges and deferred income | Subtracted | Subtracted |
All these lines are on the full, abbreviated and micro models, so both figures work for virtually every Belgian company that files. Receivables over one year (29) stay out. How to read a Belgian balance sheet shows where each line sits.
Seen from the top of the balance sheet, net working capital is equity (10/15), provisions (16) and debts over one year (17) minus formation expenses (20), fixed assets (21/28) and receivables over one year (29). Positive means long-term money funds part of the current assets; negative means short-term creditors fund part of the fixed assets. It is also the current ratio in euros: the National Bank's broad liquidity ratio divides the same assets by the same debts, as explained in liquidity ratios in Belgian annual accounts.
The working capital requirement
A large net working capital is not automatically good. The National Bank notes it can simply mean too much stock, and that it assumes current assets turn into cash exactly when short-term debts fall due, which is rare. What matters is how much the business needs: the operating needs (stocks, receivables) minus the operating resources (credit from suppliers, staff, the tax authorities and customers paying in advance).
Working capital requirement = 3 + 40/41 + 490/1 minus (44 + 45 + 46 + 47/48) minus 492/3
Cash, investments and short-term financial debts drop out: 43 and, by the usual convention, 42, the part of long-term loans repayable within the year. If you treat 42 as an operating debt, say so.
Net cash: where the two meet
Net working capital minus the requirement gives the net cash position: investments plus cash minus short-term financial debts (50/53 + 54/58 minus 42 minus 43). When net working capital exceeds the requirement, the operating cycle is fully funded. When it falls short, overdrafts and straight loans fill the gap.
The National Bank lists the levers. Net working capital improves through a capital increase, retained profit, refinancing short-term debt over the long term or selling assets. The requirement falls by collecting faster, paying suppliers later, holding less stock, or factoring and discounting; see how factoring works in Belgium.
Positive or negative: it depends on the business model
The requirement comes from timing: suppliers and staff are paid before customers pay and stock is sold. The longer that cycle, the larger the requirement. The National Bank's December 2014 analysis of the 2013 accounts shows how far sectors diverge (medians, as a percentage of total assets):
Business model | What drives it | Median requirement, 2013 |
|---|---|---|
Retail | Customers pay at the till, stock turns quickly, suppliers are paid later | -0.7% |
Accommodation and food service | Cash sales, perishable stock, almost no receivables | -24.7% |
Business services | No stock; receivables offset by debts to staff and the tax authorities | -6.1% |
Wholesale | Stock plus customers on invoice terms | 6.0% |
Construction | Contracts in progress and long payment cycles | 4.2% |
The figures are old; the pattern is structural. In a supermarket, a negative requirement means suppliers finance the shelves, and negative net working capital can be normal. A services firm that invoices after the work carries receivables but no stock, and a company billing a year in advance holds deferred income (492/3) that pushes the requirement down. In a wholesaler or contractor, negative net working capital usually means bank lines carry the business. The National Bank also warns that intra-group cash pooling distorts group companies' figures.
The cash conversion cycle in brief
The cash conversion cycle expresses the requirement in days: how long money sits between paying a supplier and being paid.
DSO (days sales outstanding) = trade receivables (40) / turnover (70) x 365. Credit management and DSO explains the VAT trap and how to bring it down.
DIO (days inventory outstanding) = stocks (3) / goods and raw materials consumed (60) x 365.
DPO (days payable outstanding) = trade debts (44) / purchases (60 + 61) x 365.
Cash conversion cycle = DSO + DIO minus DPO.
The National Bank's customer and supplier credit ratios also add VAT (9146, 9145) to the denominators, which only the full model shows. On the abbreviated and micro models, turnover (70) and purchases (60/61) are optional and 60/61 is one line, so small companies usually give you the requirement in euros but not the cycle in days.
A worked example
An illustrative Mechelen distributor files the full model: turnover (70) 4,800,000 euros, goods consumed (60) 3,400,000 euros, services and other goods (61) 420,000 euros. Its balance sheet at 31 December:
Line | Code | Amount |
|---|---|---|
Stocks | 3 | €620,000 |
Trade receivables | 40 | €780,000 |
Other receivables | 41 | €60,000 |
Cash | 54/58 | €140,000 |
Deferred charges and accrued income | 490/1 | €20,000 |
Long-term debts due within the year | 42 | €80,000 |
Financial debts (straight loan) | 43 | €250,000 |
Trade debts | 44 | €510,000 |
Taxes, remuneration and social security | 45 | €150,000 |
Other debts | 47/48 | €30,000 |
Accrued charges and deferred income | 492/3 | €20,000 |
Net working capital: 1,620,000 current assets minus 1,020,000 short-term debts minus 20,000 accruals = 580,000 euros. The current ratio is 1.56.
Working capital requirement: 620,000 + 840,000 + 20,000 minus (510,000 + 150,000 + 30,000) minus 20,000 = 770,000 euros.
Net cash: 580,000 minus 770,000 = minus 190,000 euros, the same as 140,000 cash minus 330,000 short-term financial debt. The bank funds part of the cycle.
Cycle: DSO 59 days, DIO 67 days, DPO 49 days, so 59 + 67 minus 49 = 77 days.
The current ratio looks fine, yet the company leans on its straight loan. One day of DSO is worth about 13,150 euros here (4,800,000 / 365); collecting ten days faster frees roughly 131,500 euros, most of the gap. The cash flow side is in cash flow in Belgian annual accounts.
Working capital for many companies at once
By hand this takes minutes per filing, which does not scale to a customer or prospect list. Bizzy shows, on the Financials tab of each Belgian legal entity, four years of figures from the accounts filed with the National Bank, including Net Working Capital and Net Working Capital Requirement next to cash, cash flow, the current ratio and the quick ratio, with the filed PDF per year to check the source lines.

Frequently asked questions
Is working capital the same as net working capital? Mostly yes: in Belgium "werkkapitaal" or "bedrijfskapitaal" usually means net working capital. The working capital requirement is a different figure that leaves out cash and financial debts.
Is negative working capital always bad? No. Retailers and hospitality businesses paid immediately often have a negative requirement because suppliers finance their stock. Where sales are on invoice terms, negative net working capital usually means short-term creditors fund long-term assets.
Where do I find the figures? In the filed annual accounts, free to consult at the National Bank; the balance sheet holds every line both formulas need.
Can I calculate working capital for a micro company? Yes, every balance sheet line needed is on the micro model. The cash conversion cycle usually is not, because turnover and purchases are optional.
