Cost of living

Rent, groceries, energy, transport — comparison per region and with the Netherlands

Summary

Belgium is on average 10-20% cheaper than the Netherlands in terms of housing costs, but the tax burden is higher. Total costs depend heavily on your region: Brussels is comparable to Amsterdam, while the Ardennes or Belgian Limburg can be 40-50% cheaper. This chapter provides a detailed overview of all costs you can expect, based on current figures from 2025-2026.

What you need to know

Rental prices

The Belgian rental market is less overheated than the Dutch one. There's more supply, and rental prices are regulated through rental law. Rent indexation is linked to the health index (not freely adjustable by the landlord).
