The grace period as American cards describe it, a countdown of interest-free days after each purchase, appears on none of the Belgian issuer pages I read. What exists here is a deferred collection. It costs nothing if you pay everything, and it loses its point the moment you carry one euro over.
What is a credit card grace period?
It is a delay during which a purchase generates no interest, provided you settle the statement in full. The term comes from the American market, where each statement states the number of days granted.
In Belgium the word circulates on comparison sites and forums, and rarely in contracts. Contracts speak of deferred debit, statement date, credit used. Confusion is common: people look for a delay in a contract that holds only a date.
Is there an interest-free period on Belgian cards?
Not under that name, and not for a guaranteed number of days. Wikifin, the financial-education site of the FSMA, the Belgian financial services authority, describes two regimes. On a deferred-debit card, everything is collected on a fixed day of the month and "you pay no interest on the sums you pay with your credit card". On a card tied to a credit facility (an "ouverture de crédit"), staggered repayment brings "very high interest" on what remains.
Neither text promises a number of days. I found no such obligation in Book VII of the Code of Economic Law, the part that governs consumer credit in Belgium: a free credit repayable in one go in the short term simply falls outside the consumer credit regime (article VII.3).
The figure to remember: zero guaranteed days, one collection date.
How many interest-free days at KBC and at Beobank?
At KBC, the length is deduced from a calendar. The statement of spending goes out around the 20th, the monthly settlement arrives on the 1st, and the amount is collected that day. A purchase of 5 September is therefore collected on 1 October, 26 days later. A purchase of 21 September waits until 1 November: 41 days. Both durations are my calculation, drawn from the calendar KBC publishes, to be checked against your contract.
At Beobank, the Visa Classic page gives no date. It states a monthly statement and the option of a direct debit. The interest rule sits in the general conditions: no interest is calculated if the total amount due is repaid by the statement deadline.
| Card | Annual fee | APR | Interest-free days | Rate surveyed on |
|---|---|---|---|---|
| KBC credit card | not published (the APR calculation assumes €0) | 9.35 % with the staggered-repayment option (borrowing rate 8.97 %) | 26 to 41 days, from the calendar (my calculation) | 24/10/2026 |
| Beobank Visa Classic | €5 | 14.49 % (variable borrowing rate 13.98 %) | Not published on the page | 24/10/2026 |
| Beobank Extra Mastercard | €20 | 15.99 % (borrowing rate 14.30 %) | Not published, undated document | 24/10/2026 |
In the files I used to handle, the question "how many days do I have" almost always came after a purchase made on the 21st or 22nd of the month. The cardholder had counted thirty days. They had forty-one, or twenty-six, depending on which side of the statement cut-off the purchase fell.
What happens to the grace period when you carry a balance?
It disappears, including for later purchases. The brochure never highlights this.
Beobank's conditions are explicit: as long as the total amount due is not repaid, debit interest is calculated every day on the outstanding balance and on new card transactions. A purchase made while you are carrying €944.44 therefore gets no delay.
A worked example, at the Visa Classic's 13.98 % borrowing rate, rate surveyed on 24 October 2026. You spend €1,000 in a month and pay only the 1/18 minimum, €55.56. That leaves €944.44 carried. Over 30 days, it produces about €10.85 of interest. On day ten you buy €200 of goods: those €200 still cost about €1.53 over the remaining 20 days. Paid in full, the same €200 would have cost nothing. All these amounts are my own calculations, in simple interest, as an order of magnitude.
At KBC, the text reads a little more favourably: under staggered repayment, interest applies only to the deferred period and amount.
Do ATM withdrawals get a delay?
Beobank's document shows no delay of their own: a withdrawal follows the logic of purchases. What sets it apart is its fees, which apply immediately: 2.50 % of the amount withdrawn, with a minimum of €5 and a maximum of €15 per withdrawal. The withdrawal is free if the card account holds a credit balance of at least the amount withdrawn.
For €100, that is €5. Over twelve months, with one €100 withdrawal a month, that makes €60 in fees, before the €5 annual fee.

At KBC, a transfer from the card balance to your current account bears interest from the transfer date. Another, quieter trap: a withdrawal or a transfer turns what was a payment into a loan.
Is Buy Way's zeroing obligation a grace period?
No. It is the opposite of a gift: an imposed deadline. In its explanatory sheet, Buy Way describes "zérotage" (zeroing) as the legal obligation, set by Belgian consumer credit rules, to repay in full the credit used, with fees and interest, before a deadline.
For a contract signed after 31 December 2012, that period is stated in the contract. The issuer warns you 8 months and then 2 months before it ends. The sheet's example: a €2,500 credit with a card gives a 41-month period, which restarts each time the balance reaches zero. The minimums on the statement may not be enough to reach zero in time.
If zeroing does not happen, use of the credit is first suspended. A lasting default is recorded on the negative side of the Central Individual Credit Register (the "Centrale des Crédits aux Particuliers"), run by the National Bank of Belgium. Buy Way publishes neither an APR nor a fee on that sheet, so I do not cite any of its cards with a rate.
Where do you read the exact rule in your contract?
The issuer looks first at the statement date, then at the payment deadline. You should do the same, with four lines:
- the collection date, or the formula that sets it ("the first day of the month", "by the statement deadline");
- the sentence on how interest is calculated when a balance remains: on the balance alone, or on new purchases too;
- the APR of the carried balance, with its worked example;
- the date on which the rate was surveyed at the issuer.
A line is missing? Write to the issuer. A written answer is worth more than a memory of what someone said at a branch counter.
If carrying a balance becomes heavy, an accredited debt mediation service or your commune's CPAS (the public social welfare centre) can help you free of charge. A missed payment has its own consequences, described in the article on late payment. This article gives landmarks, not advice on your situation.
To compare cards on their numbers, the ranking of Belgian credit cards, the comparison tool and the selection guide start from the same surveyed rates. The monthly collection mechanism is detailed in the article on deferred debit, the gap between interest and total cost in the one on APR and borrowing rate, and the floor payment in the one on the minimum payment.

Delphine a passé sept ans au service litiges et rétrofacturation d’un émetteur de cartes belge, à Liège, entre 2015 et 2022 : le bureau où atterrissent les contestations de porteurs, les retraits facturés deux fois et les cautions d’hôtel qui restent bloquées trois semaines. Elle a donc lu, ligne par ligne, plusieurs milliers de relevés de cartes belges, et elle sait où se logent les montants que personne ne regarde avant de signer. Depuis 2023 elle relève chaque trimestre les tarifs publiés des émetteurs belges et tient le tableau de coûts qui sert de base à ce site. Ce qui l’agace : les brochures qui annoncent une carte à 0 € sans mentionner que le premier retrait au distributeur coûte 5 € fixes plus 1,8 % de commission, et que les intérêts courent dès le jour du retrait.
