📐 About This Calculator
Income tax is usually charged in progressive slabs: each band of income is taxed at its own rate. This shows the tax per slab, your effective and marginal rates, and net income.
Variable Definitions:
- • Effective rate = Total tax ÷ gross income
- • Marginal rate = Rate on your next unit of income
✅ Best used for:
- • Estimating annual tax
- • Comparing take-home across incomes
- • Understanding your bracket
⚠️ Limitations:
- • Frontend uses illustrative slabs; the full 175+ country dataset is admin-managed
- • Excludes some allowances, surcharges and local taxes
📖 How Income Tax is Calculated
Slab, flat and zero systems
Slab systems tax income in progressive bands; flat systems apply one rate; some jurisdictions levy no personal income tax at all.
Effective vs marginal rate
Your marginal rate is the rate on your next unit of income; your effective rate is the average across all your income — always lower than the marginal rate under a slab system.
