Calculation
The band follows from the bankruptcy probability. 10 more points roughly halve it.
| 75-100 | Excellent | under 0.55% |
| 60-74 | Healthy | 0.55% to 1.5% |
| 45-59 | Fair | 1.5% to 4.2% |
| 25-44 | Weak | 4.2% to 15.0% |
| 0-24 | Critical | over 15.0% |
Where the company stands within its band depends half on the bankruptcy probability and half on how it does against its sector peers (NACE 68, micro). It does better than 55% of them on solvency, 17% on liquidity, 18% on profitability and 22% on growth.
The bankruptcy probability was computed on 09-11-2026 by the bankruptcy model of 2 October 2026, which learns from Belgian bankruptcies and reads the registers, the annual accounts and the Belgian Official Gazette.
The probability rests on the annual accounts with balance sheet date 31-12-2025.
Of the companies with a bankruptcy probability in the very low class on 30-06-2025, 0.1% went bankrupt within twelve months.
Some facts cap the score, however low the probability. With negative or zero equity, a heavy loss, a special status in the KBO, one missing filing or accounts filed more than 90 days late, the score is Fair at most (59). With two missing filings, it is Weak at most (44). During a judicial reorganisation or at the company's end (bankruptcy, dissolution, liquidation), it is Critical at most (24).
Credit verdict
Credit of up to €30,000 on 30-day terms is acceptable
Liquidity is insufficient, with a current ratio of 0.84 (1.43 in 2024), below 1. Short-term debt is 57% and cash 0.4% of total assets. 62.1% of the assets are financed with debt and provisions.

Nearly half (47%) of Belgian companies file late; of those that file 1 to 90 days late, 2.0% are now bankrupt, dissolved or in another special legal status, against 1.66% of all filers.
