A general estimator

Real income tax uses progressive brackets, credits, and rules that vary by country and year. This calculator is a fast general estimator: it applies a single average (effective) rate to your taxable income. For an exact figure, use your jurisdiction's official tax tables or a professional.

Frequently Asked Questions

Does this use tax brackets?

No — it applies one average rate you provide, which keeps it simple and country-agnostic. Bracket-based tax requires jurisdiction-specific tables.

What average rate should I enter?

Use your effective (average) tax rate — total tax divided by income — not your top marginal bracket, which only applies to your last dollars earned.

Is this calculator free and private?

Yes. It's completely free with no signup, and every calculation runs locally in your browser, so your numbers never leave your device.
