Tax Bracket Calculator

See exactly how much tax each bracket contributes and where you sit within your band.

Please note: A general estimate, not tax advice. Rates, bands, allowances and rules differ by country and change frequently. Enter the figures that apply to you and confirm with a qualified tax professional or your tax authority.

What the Tax Bracket Calculator does

This shows the mechanics of progressive taxation band by band: how much income falls in each, what it costs, and how much room remains before the next threshold. That last figure matters for timing bonuses or deductible contributions.

Formula

Income in band = min(Income, Band top) − Band bottom, floored at zero
Band tax = Income in band × Band rate
Total tax = Sum across all bands

Inputs explained

Input	Unit	Required	Notes
Taxable income	selected currency	Yes	Accepts more than 0.
Bracket thresholds	text	Yes	The income level where each band starts. Always begin with 0. The greyed-out example shows the format only — it is not a current rate table for any country.
Bracket rates (%)	text	Yes	One rate per threshold, in the same order. Use the bands published by your own tax authority for the year you are calculating.
Currency	one of 10 options	Optional	—

How to use it

Worked example

Taxable income of $70,400 across bands at 0/11,000/44,725/95,375 taxed 10/12/22/24%.

Income: 70400
Thresholds: 0, 11000, 44725, 95375
Rates: 10, 12, 22, 24

Top bracket 22%, total tax $10,796, effective rate 15.3%, with $24,975 of room before the 24% band.

Frequently asked questions

Why is my effective rate so much lower than my bracket?

Because only the top slice of your income is taxed at your bracket rate. Everything below is taxed at the lower band rates.

How can I use the headroom figure?

It shows how much more you can earn before the next rate applies — useful when timing a bonus, a sale, or a deductible retirement contribution.

Method and sources

Method. Income is sliced against the band thresholds entered, and each slice taxed at its own rate — the marginal structure most income-tax systems use.

Assumptions

Bands ascend from zero and apply marginally, so only income above a threshold is taxed at that band's rate.
The bands entered are complete; a missing top band silently taxes high income at the wrong rate.

Limitations

Shows one tax on one income. Social contributions, local taxes and surcharges are excluded unless folded into the bands by hand.
Real systems layer phase-outs, cliff edges and separate schedules for different income types that a flat list of bands cannot express.
No rate table ships with this calculator: you supply the rates, so the result follows whichever jurisdiction and year you enter. That means it can never go silently out of date — but it also cannot warn you if the figures you entered are.
