How the 2026 figures are produced. The share-of-GDP figure is a per-country estimate researched from announced and enacted national defence budgets. The dollar figure is not a per-country forecast — it is the actual SIPRI figure for 2025 raised by a flat 5%, the same rate applied to every country in this group, so it can rise even where the share-of-GDP path falls. Actual SIPRI figures for Belgium run to 2025.
