Credit Card Repayment in Belgium: How It Works in 2026

When you use a credit card in Belgium, money isn't debited right away. The question that follows: how and when do you need to repay? There are two very different mechanisms, and mixing them up can be costly. This guide covers how repayment actually works, the real costs by bank, and the Belgian legal framework.

What Are the Two Credit Card Repayment Methods?

In Belgium, credit card repayment follows one of two models: deferred debit or revolving credit (known locally as "ouverture de crédit").

Deferred debit is the most common. Your bank tallies your monthly spending and debits the full amount from your current account on a fixed date, usually between the 1st and 10th of the following month. You pay zero interest. This is the default for Visa and Mastercard cards at ING, BNP Paribas Fortis, KBC, Belfius and Argenta.

Revolving credit works differently. The bank grants you a credit reserve (typically €500 to €5,000) and debits only a minimum amount each month. The remaining balance accrues interest, sometimes for years. You'll find this at Beobank, Cofidis, Cetelem, or through options like KBC's "Flex Budget" and BNP Paribas Fortis's "Optiline."

The test is straightforward: if your card automatically debits 100% of your spending each month, it's deferred debit. If you can "spread" the repayment, it's revolving credit.

What Is the Minimum Monthly Repayment?

For revolving credit facilities, Belgian law sets a minimum monthly repayment of 1/18th of the outstanding balance when the credit line doesn't exceed €5,000 (about 5.6%). Above €5,000, the minimum drops to 1/20th (5%). In all cases, the absolute floor is €25 per instalment (source: Wikifin.be, FSMA).

What this means for you: if you've spent €1,000 on your revolving credit card, the bank debits a minimum of €56 the following month. The remaining €944 starts accruing interest immediately.

How Much Does Minimum Repayment Cost Over a Year?

Take a single €1,000 purchase repaid at the strict minimum, with an APR of 12.50% (ING's rate). After 12 months, you'll have paid about €670, including over €100 in interest, with roughly €430 still outstanding. Over the full repayment period (about 18 months), total interest exceeds €150.

Important detail: this assumes you don't add any new spending during that time. Most users keep spending on their card, which pushes back the repayment timeline and inflates the cost.

What APR Do Belgian Banks Charge in 2026?

Rates vary nearly twofold depending on the issuer. Here are the APRs for the main Belgian banks' revolving credit cards (data: June 2026, sources: official bank websites):

The cap is set by the SPF Economy and revised every six months. Since 1 December 2025, it stands at 14.50% for card-based credit facilities between €1,250 and €5,000.

I simulated a €2,000 instalment plan over 12 months in early 2025 using my ING card at 12.50%. Result: about €140 in interest. The same amount at KBC's 9.35% would have cost roughly €100. A €40 difference on a single purchase, purely down to the rate.

Is There a Legal Interest Rate Cap?

Yes. The maximum authorised APRs apply to all forms of consumer credit in Belgium. For card-based credit facilities, the current caps are: 16.50% for amounts up to €1,250, 14.50% between €1,250 and €5,000, and 13.50% above €5,000. If a bank exceeds these caps, the consumer is exempt from paying any credit costs whatsoever.

How Does the Zero-Reset Rule Work in Belgium?

The "zérotage" (zero-reset) is the legal obligation to fully repay all credit used within a maximum timeframe. For credit lines up to €5,000, the deadline is 60 months (5 years). Above €5,000, it extends to 96 months (8 years). The zero-reset date appears in your contract and starts from the first time you use the credit (source: UPC-BVK).

If you don't hit zero by the deadline, three consequences follow: your card is blocked, the contract can be terminated, and the lender registers a payment default at the Central Individual Credit Register (CCP) of the National Bank of Belgium. A CCP flag makes it very difficult to obtain any new credit, including mortgages, for at least one year after regularisation.

In March 2026, the BNB still counted over 350,000 defaulting credit contracts in Belgium. The zero-reset rule is a safety net against over-indebtedness, but it doesn't protect you from the interest costs accumulated over 5 years of minimum payments.

Should You Repay in Full or in Instalments?

Full monthly repayment is always preferable. At an APR between 9% and 14.5%, every euro left unpaid costs you in interest. A €3,000 purchase spread over 3 years at 12.50% generates over €600 in hidden costs. The same purchase paid off at month's end: €0.

If your budget doesn't always allow full repayment, there's an alternative: neobanks. Revolut, N26 and Wise don't offer credit at all. Money is debited immediately, eliminating any interest risk. I've been using this strategy since late 2024 with a Revolut Standard for everyday spending and an ING credit card reserved solely for car rentals (which often require a credit card as deposit). Result: zero interest paid over 18 months.

If you rarely travel and don't need the deposit guarantee of a credit card, it's worth asking: do you actually need a revolving credit option? If not, a debit card or neobank account will do, with no zero-reset risk or CCP exposure.
