About Rijksbegroting Dashboard
An interactive dashboard on the Dutch national budget: move expenditure and revenue and see what happens to the EMU balance, the national debt and the budget norms. The figures come from open data of the Dutch government, Statistics Netherlands (CBS), the CPB and Eurostat; the rules from the fiscal key table, the CPB behavioural rules, Saffier 3.0 and the 2026 budget rules.
Disclaimer
This is not an official assessment by the CPB Netherlands Bureau for Economic Policy Analysis or the Ministry of Finance. The results are indicative: a linear, deterministic approximation on public sources and rules of thumb, without interest feedback on the debt and without the expert judgement the CPB applies in Keuzes in Kaart.
The Freemium mode computes statically (layer 1 and norms). The Pro mode adds first-order behavioural effects (CPB/MinFin, 2026) and macro effects (CPB Saffier 3.0 variants, 2023), scaled linearly per impulse category. Outside a key's validated range the result is explicitly indicative.
How far the engine deviates from the CPB is listed per measure in the public KiK deviation report.
