Cash flow and self-financing capacity
Accounting profit is not money. Cash flow, or self-financing capacity, comes closer: it is what the year's business actually generated to repay, invest or distribute.

Key points
- Simplified cash flow = result for the year (9904) + depreciation and write-downs (630 + 631/4 + 635/8).
- The NBB uses a complete definition: it also adds financial and non-recurring charges, removes reversals and corrects for deferred taxes.
- Divided by third-party funds (16 + 17 + 42/48 + 492/3), cash flow measures repayment capacity (IBR-IRE, chapter 2).
- Positive cash flow despite an accounting loss often signals heavy depreciation, not a business burning cash.
From profit to cash flow
| 9904 | Profit for the year | 61 930€ | |
| 630/634 | Depreciation and write-downs | 56 470€ | |
| CF | Simplified cash flow | 118 400€ | The business generates cash |
The simplified calculation
Cash flow = result for the year (9904) + depreciation, write-downs and provisions (630 + 631/4 + 635/8)
This is the version that can always be computed from a filing, abridged included: in the abridged and micro formats, 630 does not appear separately but the charges are found in the notes (8079, 8279) and 631/4 and 635/8 appear in the income statement. FinScan uses this version.
The National Bank's definition
The Central Balance Sheet Office applies a more complete definition, which it uses in its ratio no. 10 (cash flow divided by equity). For the full format, cash flow is obtained as follows:
| Operation | Headings |
|---|---|
| Profit (loss) for the year | + 9904 |
| Depreciation, write-down and provision charges, operating, financial and non-recurring | + 630 + 631/4 + 635/8 + 651 + 6501 + 6560 − 6561 + 660 + 661 + 662 |
| Reversals of depreciation, write-downs and provisions | − 760 − 761 − 762 |
| Losses on disposal of fixed assets | + 663 |
| Transfers from deferred taxes | − 780 |
| Transfers to deferred taxes | + 680 |
For the abridged and micro formats, the NBB uses the available headings: + 9904 + 631/4 + 635/8 + 8079 + 8279 + 8475 − 8089 − 8289 − 8485 − 780 + 680.
The idea is the same as in the simplified version, taken all the way: every charge and every income that did not give rise to a cash movement during the year is neutralised.
What it says
Cash flow measures the company's capacity to finance by itself:
- the repayment of its debts;
- its investments for replacement or growth;
- the remuneration of the shareholders.
A company whose cash flow is lastingly negative consumes its cash or has to borrow to operate.
Repayment capacity
This is the use the IBR-IRE makes of it in the chapter devoted to solvency, with two ratios:
Coverage of third-party funds by cash flow = cash flow ÷ (16 + 17 + 42/48 + 492/3)
Coverage of long-term third-party funds by cash flow = cash flow ÷ (16 + 17)
The first says what share of total debt one year of business could repay; the second focuses on long debts. Their inverse gives the number of years of cash flow needed to repay. In the example handled by the IBR-IRE, a company covered 8.1% of its third-party funds and 38.6% of its long-term third-party funds with its annual cash flow; the study stresses that sector ratios are missing for this ratio and that it is therefore read mainly over time.
The situations to recognise
- Positive profit, positive cash flow: the normal case.
- Accounting loss, positive cash flow: heavy depreciation explains the loss; the business still generates cash. Frequent after a large investment.
- Positive profit, weak cash flow: rare; often a reversal of a provision or write-down, which is income without collection.
- Negative cash flow: the business consumes cash. Look at how many months of cash remain and how the working capital requirement evolves.
Cash flow and return on equity
The NBB also divides cash flow by equity (ratio no. 10, next to ratio no. 9 which divides the net result by equity). The gap between the two ratios measures the weight of non-cash charges: a heavily depreciated industrial company will have a ratio 10 well above its ratio 9; a service company, two close ratios.
Monthly figures for comparison
FinScan also shows monthly cash flow (cash flow ÷ 12): compared with cash and amounts payable within one year, it says in how many months the business rebuilds the till. This is a FinScan presentation, not an NBB ratio.
Frequently asked questions
Why add depreciation back to the result?
Depreciation is an accounting charge that does not take money out this year: the machine was paid for when it was bought. Adding it back to the result gives an approximation of the cash produced by the business. The NBB does the same for every non-cash charge: depreciation, write-downs, provisions.
Is cash flow equal to the change in cash?
No. Cash flow ignores the change in working capital requirement and investments: a high cash flow can be absorbed by swelling receivables or by the purchase of a machine. The year-end cash will tell.
Do FinScan and the NBB get the same figure?
Not always. FinScan uses the simplified version (result + depreciation and write-downs), computable in every format. The NBB applies a more complete definition that takes into account financial and non-recurring charges and reversals and deferred taxes. The gap is small for most SMEs, significant in case of an exceptional transaction.
