Methodology and Sources
The United States calculator is an educational model. It combines user-entered tax amounts with broad spending shares so visitors can explore how taxes may connect to public priorities.
How the estimate works
The model maps national, regional, local, and property-related taxes into broad categories such as health, education, infrastructure, public safety, debt, social support, and administration. Exact budget structures differ by country, so the calculator should be read as an approximation.
Source priorities
- Official budgets, public accounts, finance ministry reports, and audit documents should be preferred when available.
- When a more specific government source is available, it should replace broad comparative estimates.
- Corrections should include a source link, date, and category mapping suggestion where possible.
Important limits
Governments pool revenue from many sources. The model cannot identify the exact destination of each tax dollar; it gives a transparent estimate for education and comparison.
