A public budget you can test-drive
An interactive public-finance calculator for Razvojnik: change a tax or a spending line and watch Slovenia's state budget respond, through 2030.
Visit siteSlovenia's state budget is argued over constantly, yet almost no one outside the Ministry of Finance can see how the numbers fit together. Razvojnik wanted a tool that lets journalists, policymakers and citizens change a single tax or spending line and see the consequences for the whole budget.
We turned the state budget into an interactive model. Every lever — income-tax brackets, social-contribution caps, VAT, corporate tax, spending targets by sector — recalculates the balance in real time. The methodology and assumptions are documented and exportable, so the numbers can be checked, not just trusted.
Anyone can now act as finance minister: adjust the levers, compare pre-built reform scenarios, and download the underlying calculations. Public-finance debate gets a shared, transparent reference instead of competing back-of-envelope claims.

What it does
- Adjust the revenue side — income-tax rates and brackets, general allowances, social-contribution rates and caps, corporate income tax (DDPO), VAT, and employer/employee contributions.
- Adjust the expenditure side — spending targets and growth paths by sector, and deficit or surplus goals.
- See the balance move — the projected state-budget balance through 2030 recalculates as you change any lever.
Built for scrutiny
- Four ready-made scenarios — the current system plus three published reform proposals — as starting points.
- Every scenario is editable; nothing is a black box.
- Full methodology and downloadable calculations, with the linear-model assumptions stated plainly rather than hidden.
Why it matters
A budget is far easier to argue about than to understand. Making the trade-offs tangible — raise this, cut that, watch the balance move — turns an abstract debate into something anyone can actually test.
