Calculer le délai de préavis en Belgique: licenciement ou démission, en semaines
Estimates only, not financial advice. What you type stays on your device. Checked against sources on 20 Oct 2026.Depuis le statut unique de 2014, ouvriers et employés ont le même délai de préavis, compté en semaines selon l’ancienneté. Un licenciement après 7 ans donne 24 semaines; une démission ne dépasse jamais 13 semaines. Les contrats commencés à partir du 1er juin 2026 sont plafonnés à 52 semaines. Le préavis débute le lundi qui suit la semaine de sa notification, et l’indemnité de rupture vaut la rémunération mensuelle × 3/13 par semaine.

This calculator works out the statutory notice period (délai de préavis, opzegtermijn) for an open-ended Belgian employment contract that began on or after 1 January 2014, from the tables of the SPF Emploi, Travail et Concertation sociale, the federal labour ministry, read on 20 October 2026. The rules may have changed since.
Dismissal by the employer. One week under 3 months, then 3, 4 and 5 weeks, 6 weeks from 6 months, 12 weeks at 2 years, 18 weeks at 5 years, 33 weeks at 10 years, and 3 more weeks for each year up to 60 weeks at 19 years. Two changes in 2026: contracts begun from 1 June 2026 are capped at 52 weeks from 17 years, and contracts begun from 1 August 2026 get 1 week for the whole first six months.
A worked example. Hired on 1 March 2019 and dismissed by a letter that takes effect on Wednesday 14 October 2026: the notice runs from Monday 19 October 2026 for 24 weeks, to Sunday 4 April 2027.
The rest of the article, and all 6 questions about Belgium Notice Period Calculator (Préavis), are on the Belgium Notice Period Calculator (Préavis) page.
For a contract that began from 2014, an employer who dismisses a worker with 5 to 6 years of seniority gives 18 weeks of notice, and 21 weeks from 6 years. A worker who resigns after 5 years gives 9 weeks. Blue- and white-collar workers have had the same notice since the single status of 2014.
A worker who resigns never gives more than 13 weeks of notice, reached after 8 years of seniority. Under 3 months the notice is 1 week, then 2, 3, 4, 5 and 6 weeks as seniority grows. For contracts begun from 1 August 2026, the first six months carry 1 week.
Only for contracts that began on or after 1 June 2026: their dismissal notice stops at 52 weeks from 17 years of seniority. Contracts begun before then keep the full table, which the SPF Emploi shows up to 65 weeks at 23 years. Someone hired in 2014 and dismissed in 2032 gets 57 weeks.
Notice given by the employer is suspended during illness, annual holidays, maternity leave, temporary unemployment and several other absences, so it ends later than the dates shown here. Notice given by the worker is never suspended. This calculator shows the dates when nothing suspends the notice.
