How to use

Enter the income you want to process on the first line of the input area.
Add the scale below it, one line per bracket, each holding a ceiling and its rate.
Run the calculation to see the breakdown bracket by bracket and the total.
Change one value in the scale and run it again to compare two scenarios.

Example

The sample pairs an income with a three-bracket scale. After calculating, walk through the breakdown line by line to see which share of the income falls into each bracket, then compare the total with the estimate you had in mind.

Input

Limits and formats

The tool applies the scale you type and knows nothing about the tax rules or allowances of any particular country.
Bracket lines must stay consistent, with rising ceilings and one rate per line.
The total is an estimate and does not replace official tax information or advice from a professional.
Displayed rounding may differ from that of accounting software.

Where processing happens

The calculation is carried out inside your browser, with no transmission and no storage of the values you enter. You can therefore test several bracket scenarios in a row, compare the totals and leave without a trace on your device.

Frequently asked questions

What do the two numbers on each line mean?

The first is the ceiling of the bracket and the second is the rate applied to the portion of income inside it. Order matters, so keep ceilings rising from the top of the list downwards.

Can I use a scale from another country?

Yes, the tool simply applies the numbers you give it. It is up to you to confirm that the ceilings and rates match the rules of the situation you are studying.

Why does my total differ from the official figure?

Tax authorities usually apply allowances, caps and rounding rules on top of the scale. The tool only processes the brackets you entered, without those extra steps.
