Frequently asked questions
Which indexes are in this table? + −
All Statbel health indexes published in 2026 (one per month). The base 2013 = 100 remains applicable for the majority of leases. For leases signed in 2026, the new base 2025 = 100 applies — see our base 2025 index table.
Why see the 2025 indexes too? + −
To calculate an indexation on your 2026 anniversary date, you need both indexes: the one for the month preceding the lease signature (often in the past) and the one for the month preceding the 2026 anniversary date (in this page). The table includes 2025 + 2026 to facilitate comparison.
How to export this data? + −
