Progressive tax systems apply higher rates only to the income within each bracket, not your entire income at the top rate. This calculator uses an illustrative bracket structure to show exactly how that adds up.
Important: illustrative brackets, not your actual tax code
Real tax brackets vary by country, change periodically, and depend on filing status and other factors. This calculator uses a simplified, illustrative bracket table to demonstrate how progressive taxation works — it is not a substitute for checking your actual local tax rules or consulting a tax professional.
Effective rate vs. marginal rate
Your marginal rate is what you pay on your last dollar earned. Your effective rate — the number that actually matters for 'how much of my income goes to tax' — is always lower, because earlier income was taxed at lower bracket rates first.
