Add each journey you're going to make (outbound, return, or as many as you need), with its date and approximate time. The calculator automatically detects whether peak, off-peak, or weekend/holiday pricing applies, and shows you the total price with and without Train+.
Children under 12 travel completely free (no ticket or Train+ card needed), as long as they're accompanied by an adult with a valid ticket. One adult can bring up to 4 children for free. No need to add them as a separate journey in this calculator — just calculate the adults' tickets.
Standard and Off-peak/Anytime (Train+) ticket prices are taken from official SNCB/NMBS sales for weekday journeys. Weekend/holiday prices are calculated by applying the official discount rules (-30% automatic, -40% extra with Train+, cap per journey). Belgian public holidays are detected automatically. Always check the final price at belgiantrain.be before buying.
